PRIOR to this, no complete, authentic, and authorized record of the work
of Mr. Edison, during an active life, has been given to the world. That life,
if there is anything in heredity, is very far from finished; and while it
continues there will be new achievement.
An insistently expressed desire on the part of the public for a definitive
biography of Edison was the reason for the following pages. The present
authors deem themselves happy in the confidence reposed in them, and in
the constant assistance they have enjoyed from Mr. Edison while preparing
these pages, a great many of which are altogether his own. This co-
operation in no sense relieves the authors of responsibility as to any of the
views or statements of their own that the book contains. They have realized
the extreme reluctance of Mr. Edison to be made the subject of any
biography at all; while he has felt that, if it must be written, it were best
done by the hands of friends and associates of long standing, whose
judgment and discretion he could trust, and whose intimate knowledge of
the facts would save him from misrepresentation.
The authors of the book are profoundly conscious of the fact that the
extraordinary period of electrical development embraced in it has been
prolific of great men. They have named some of them; but there has been
no idea of setting forth various achievements or of ascribing distinctive
merits. This treatment is devoted to one man whom his fellow-citizens have
chosen to regard as in many ways representative of the American at his
finest flowering in the field of invention during the nineteenth century.
It is designed in these pages to bring the reader face to face with Edison;
to glance at an interesting childhood and a youthful period marked by a
capacity for doing things, and by an insatiable thirst for knowledge; then to
accompany him into the great creative stretch of forty years, during which
he has done so much. This book shows him plunged deeply into work for
which he has always had an incredible capacity, reveals the exercise of his
unsurpassed inventive ability, his keen reasoning powers, his tenacious
memory, his fertility of resource; follows him through a series of
innumerable experiments, conducted methodically, reaching out like rays of

search-light into all the regions of science and nature, and finally exhibits
him emerging triumphantly from countless difficulties bearing with him in
new arts the fruits of victorious struggle.
These volumes aim to be a biography rather than a history of electricity,
but they have had to cover so much general ground in defining the relations
and contributions of Edison to the electrical arts, that they serve to present a
picture of the whole development effected in the last fifty years, the most
fruitful that electricity has known. The effort has been made to avoid
technique and abstruse phrases, but some degree of explanation has been
absolutely necessary in regard to each group of inventions. The task of the
authors has consisted largely in summarizing fairly the methods and
processes employed by Edison; and some idea of the difficulties
encountered by them in so doing may be realized from the fact that one
brief chapter, for example,—that on ore milling—covers nine years of most
intense application and activity on the part of the inventor. It is something
like exhibiting the geological eras of the earth in an outline lantern slide, to
reduce an elaborate series of strenuous experiments and a vast variety of
ingenious apparatus to the space of a few hundred words.
A great deal of this narrative is given in Mr. Edison's own language, from
oral or written statements made in reply to questions addressed to him with
the object of securing accuracy. A further large part is based upon the
personal contributions of many loyal associates; and it is desired here to
make grateful acknowledgment to such collaborators as Messrs. Samuel
Insull, E. H. Johnson, F. R. Upton, R. N Dyer, S. B. Eaton, Francis Jehl, W.
S. Andrews, W. J. Jenks, W. J. Hammer, F. J. Sprague, W. S. Mallory, and
C. L. Clarke, and others, without whose aid the issuance of this book would
indeed have been impossible. In particular, it is desired to acknowledge
indebtedness to Mr. W. H. Meadowcroft not only for substantial aid in the
literary part of the work, but for indefatigable effort to group, classify, and
summarize the boundless material embodied in Edison's note-books and
memorabilia of all kinds now kept at the Orange laboratory.
Acknowledgment must also be made of the courtesy and assistance of Mrs.
Edison, and especially of the loan of many interesting and rare photographs
from her private collection.

CHAPTER I
THE AGE OF ELECTRICITY
THE year 1847 marked a period of great territorial acquisition by the
American people, with incalculable additions to their actual and potential
wealth. By the rational compromise with England in the dispute over the
Oregon region, President Polk had secured during 1846, for undisturbed
settlement, three hundred thousand square miles of forest, fertile land, and
fisheries, including the whole fair Columbia Valley. Our active "policy of
the Pacific" dated from that hour. With swift and clinching succession came
the melodramatic Mexican War, and February, 1848, saw another vast
territory south of Oregon and west of the Rocky Mountains added by treaty
to the United States. Thus in about eighteen months there had been pieced
into the national domain for quick development and exploitation a region as
large as the entire Union of Thirteen States at the close of the War of
Independence. Moreover, within its boundaries was embraced all the great
American gold-field, just on the eve of discovery, for Marshall had detected
the shining particles in the mill-race at the foot of the Sierra Nevada nine
days before Mexico signed away her rights in California and in all the
vague, remote hinterland facing Cathayward.
Equally momentous were the times in Europe, where the attempt to
secure opportunities of expansion as well as larger liberty for the individual
took quite different form. The old absolutist system of government was fast
breaking up, and ancient thrones were tottering. The red lava of deep
revolutionary fires oozed up through many glowing cracks in the political
crust, and all the social strata were shaken. That the wild outbursts of
insurrection midway in the fifth decade failed and died away was not
surprising, for the superincumbent deposits of tradition and convention
were thick. But the retrospect indicates that many reforms and political
changes were accomplished, although the process involved the exile of not
a few ardent spirits to America, to become leading statesmen, inventors,
journalists, and financiers. In 1847, too, Russia began her tremendous
march eastward into Central Asia, just as France was solidifying her first

march eastward into Central Asia, just as France was solidifying her first
Page 15
gains on the littoral of northern Africa. In England the fierce fervor of the
Chartist movement, with its violent rhetoric as to the rights of man, was
sobering down and passing pervasively into numerous practical schemes for
social and political amelioration, constituting in their entirety a most
profound change throughout every part of the national life.
Into such times Thomas Alva Edison was born, and his relations to them
and to the events of the past sixty years are the subject of this narrative.
Aside from the personal interest that attaches to the picturesque career, so
typically American, there is a broader aspect in which the work of the
"Franklin of the Nineteenth Century" touches the welfare and progress of
the race. It is difficult at any time to determine the effect of any single
invention, and the investigation becomes more difficult where inventions of
the first class have been crowded upon each other in rapid and bewildering
succession. But it will be admitted that in Edison one deals with a central
figure of the great age that saw the invention and introduction in practical
form of the telegraph, the submarine cable, the telephone, the electric light,
the electric railway, the electric trolley-car, the storage battery, the electric
motor, the phonograph, the wireless telegraph; and that the influence of
these on the world's affairs has not been excelled at any time by that of any
other corresponding advances in the arts and sciences. These pages deal
with Edison's share in the great work of the last half century in abridging
distance, communicating intelligence, lessening toil, improving
illumination, recording forever the human voice; and on behalf of inventive
genius it may be urged that its beneficent results and gifts to mankind
compare with any to be credited to statesman, warrior, or creative writer of
the same period.
Viewed from the standpoint of inventive progress, the first half of the
nineteenth century had passed very profitably when Edison appeared—
every year marked by some notable achievement in the arts and sciences,
with promise of its early and abundant fruition in commerce and industry.
There had been exactly four decades of steam navigation on American
waters. Railways were growing at the rate of nearly one thousand miles
annually. Gas had become familiar as a means of illumination in large
cities. Looms and tools and printing-presses were everywhere being
liberated from the slow toil of man-power. The first photographs had been
taken. Chloroform, nitrous oxide gas, and ether had been placed at the
service of the physician in saving life, and the revolver, guncotton, and

sobering down and passing pervasively into numerous practical schemes for

Page 16
nitroglycerine added to the agencies for slaughter. New metals, chemicals,
and elements had become available in large numbers, gases had been
liquefied and solidified, and the range of useful heat and cold indefinitely
extended. The safety-lamp had been given to the miner, the caisson to the
bridge-builder, the anti-friction metal to the mechanic for bearings. It was
already known how to vulcanize rubber, and how to galvanize iron. The
application of machinery in the harvest-field had begun with the embryonic
reaper, while both the bicycle and the automobile were heralded in
primitive prototypes. The gigantic expansion of the iron and steel industry
was foreshadowed in the change from wood to coal in the smelting
furnaces. The sewing-machine had brought with it, like the friction match,
one of the most profound influences in modifying domestic life, and
making it different from that of all preceding time.
Even in 1847 few of these things had lost their novelty, most of them
were in the earlier stages of development. But it is when we turn to
electricity that the rich virgin condition of an illimitable new kingdom of
discovery is seen. Perhaps the word "utilization" or "application" is better
than discovery, for then, as now, an endless wealth of phenomena noted by
experimenters from Gilbert to Franklin and Faraday awaited the invention
that could alone render them useful to mankind. The eighteenth century,
keenly curious and ceaselessly active in this fascinating field of
investigation, had not, after all, left much of a legacy in either principles or
appliances. The lodestone and the compass; the frictional machine; the
Leyden jar; the nature of conductors and insulators; the identity of
electricity and the thunder-storm flash; the use of lightning-rods; the
physiological effects of an electrical shock—these constituted the bulk of
the bequest to which philosophers were the only heirs. Pregnant with
possibilities were many of the observations that had been recorded. But
these few appliances made up the meagre kit of tools with which the
nineteenth century entered upon its task of acquiring the arts and
conveniences now such an intimate part of "human nature's daily food" that
the average American to-day pays more for his electrical service than he
does for bread.
With the first year of the new century came Volta's invention of the
chemical battery as a means of producing electricity. A well-known Italian
picture represents Volta exhibiting his apparatus before the young
conqueror Napoleon, then ravishing from the Peninsula its treasure of

ancient art and founding an ephemeral empire. At such a moment this gift
of despoiled Italy to the world was a noble revenge, setting in motion
incalculable beneficent forces and agencies. For the first time man had
command of a steady supply of electricity without toil or effort. The useful
results obtainable previously from the current of a frictional machine were
not much greater than those to be derived from the flight of a rocket. While
the frictional appliance is still employed in medicine, it ranks with the flint
axe and the tinder-box in industrial obsolescence. No art or trade could be
founded on it; no diminution of daily work or increase of daily comfort
could be secured with it. But the little battery with its metal plates in a weak
solution proved a perennial reservoir of electrical energy, safe and
controllable, from which supplies could be drawn at will. That which was
wild had become domesticated; regular crops took the place of haphazard
gleanings from brake or prairie; the possibility of electrical starvation was
forever left behind.
Immediately new processes of inestimable value revealed themselves;
new methods were suggested. Almost all the electrical arts now employed
made their beginnings in the next twenty-five years, and while the more
extensive of them depend to-day on the dynamo for electrical energy, some
of the most important still remain in loyal allegiance to the older source.
The battery itself soon underwent modifications, and new types were
evolved—the storage, the double-fluid, and the dry. Various analogies next
pointed to the use of heat, and the thermoelectric cell emerged, embodying
the application of flame to the junction of two different metals. Davy, of the
safety-lamp, threw a volume of current across the gap between two sticks of
charcoal, and the voltaic arc, forerunner of electric lighting, shed its bright
beams upon a dazzled world. The decomposition of water by electrolytic
action was recognized and made the basis of communicating at a distance
even before the days of the electromagnet. The ties that bind electricity and
magnetism in twinship of relation and interaction were detected, and
Faraday's work in induction gave the world at once the dynamo and the
motor. "Hitch your wagon to a star," said Emerson. To all the coal-fields
and all the waterfalls Faraday had directly hitched the wheels of industry.
Not only was it now possible to convert mechanical energy into electricity
cheaply and in illimitable quantities, but electricity at once showed its
ubiquitous availability as a motive power. Boats were propelled by it, cars

Not only was it now possible to convert mechanical energy into electricity

Page 18
were hauled, and even papers printed. Electroplating became an art, and
telegraphy sprang into active being on both sides of the Atlantic.
At the time Edison was born, in 1847, telegraphy, upon which he was to
leave so indelible an imprint, had barely struggled into acceptance by the
public. In England, Wheatstone and Cooke had introduced a ponderous
magnetic needle telegraph. In America, in 1840, Morse had taken out his
first patent on an electromagnetic telegraph, the principle of which is
dominating in the art to this day. Four years later the memorable message
"What hath God wrought!" was sent by young Miss Ellsworth over his
circuits, and incredulous Washington was advised by wire of the action of
the Democratic Convention in Baltimore in nominating Polk. By 1847
circuits had been strung between Washington and New York, under private
enterprise, the Government having declined to buy the Morse system for
$100,000. Everything was crude and primitive. The poles were two hundred
feet apart and could barely hold up a wash-line. The slim, bare, copper wire
snapped on the least provocation, and the circuit was "down" for thirty-six
days in the first six months. The little glass-knob insulators made seductive
targets for ignorant sportsmen. Attempts to insulate the line wire were
limited to coating it with tar or smearing it with wax for the benefit of all
the bees in the neighborhood. The farthest western reach of the telegraph

glass insulators with a little wooden pentroof for protection. In that office,
where Andrew Carnegie was a messenger boy, the magnets in use to receive
the signals sent with the aid of powerful nitric-acid batteries weighed as
much as seventy-five pounds apiece. But the business was fortunately small
at the outset, until the new device, patronized chiefly by lottery-men, had
proved its utility. Then came the great outburst of activity. Within a score of
years telegraph wires covered the whole occupied country with a network,
and the first great electrical industry was a pronounced success, yielding to
its pioneers the first great harvest of electrical fortunes. It had been a sharp
struggle for bare existence, during which such a man as the founder of
Cornell University had been glad to get breakfast in New York with a
quarter-dollar picked up on Broadway.
telegraphy sprang into active being on both sides of the Atlantic.
At the time Edison was born, in 1847, telegraphy, upon which he was to
leave so indelible an imprint, had barely struggled into acceptance by the
public. In England, Wheatstone and Cooke had introduced a ponderous
magnetic needle telegraph. In America, in 1840, Morse had taken out his
first patent on an electromagnetic telegraph, the principle of which is
dominating in the art to this day. Four years later the memorable message
"What hath God wrought!" was sent by young Miss Ellsworth over his
circuits, and incredulous Washington was advised by wire of the action of
the Democratic Convention in Baltimore in nominating Polk. By 1847
circuits had been strung between Washington and New York, under private
enterprise, the Government having declined to buy the Morse system for
$100,000. Everything was crude and primitive. The poles were two hundred
feet apart and could barely hold up a wash-line. The slim, bare, copper wire
snapped on the least provocation, and the circuit was "down" for thirty-six
days in the first six months. The little glass-knob insulators made seductive
targets for ignorant sportsmen. Attempts to insulate the line wire were
limited to coating it with tar or smearing it with wax for the benefit of all
the bees in the neighborhood. The farthest western reach of the telegraph
lines in 1847 was Pittsburg, with three-ply iron wire mounted on square
glass insulators with a little wooden pentroof for protection. In that office,
where Andrew Carnegie was a messenger boy, the magnets in use to receive
the signals sent with the aid of powerful nitric-acid batteries weighed as

CHAPTER II
EDISON'S PEDIGREE
THOMAS ALVA EDISON was born at Milan Ohio, February 11, 1847.
The State that rivals Virginia as a "Mother of Presidents" has evidently
other titles to distinction of the same nature. For picturesque detail it would
not be easy to find any story excelling that of the Edison family before it
reached the Western Reserve. The story epitomizes American idealism,
restlessness, freedom of individual opinion, and ready adjustment to the
surrounding conditions of pioneer life. The ancestral Edisons who came
over from Holland, as nearly as can be determined, in 1730, were
descendants of extensive millers on the Zuyder Zee, and took up patents of
land along the Passaic River, New Jersey, close to the home that Mr. Edison
established in the Orange Mountains a hundred and sixty years later. They
landed at Elizabethport, New Jersey, and first settled near Caldwell in that
State, where some graves of the family may still be found. President
Cleveland was born in that quiet hamlet. It is a curious fact that in the
Edison family the pronunciation of the name has always been with the long
"e" sound, as it would naturally be in the Dutch language. The family
prospered and must have enjoyed public confidence, for we find the name
of Thomas Edison, as a bank official on Manhattan Island, signed to
Continental currency in 1778. According to the family records this Edison,
great-grandfather of Thomas Alva, reached the extreme old age of 104
years. But all was not well, and, as has happened so often before, the
politics of father and son were violently different. The Loyalist movement
that took to Nova Scotia so many Americans after the War of Independence
carried with it John, the son of this stalwart Continental. Thus it came about
that Samuel Edison, son of John, was born at Digby, Nova Scotia, in 1804.
Seven years later John Edison who, as a Loyalist or United Empire
emigrant, had become entitled under the laws of Canada to a grant of six
hundred acres of land, moved westward to take possession of this property.
He made his way through the State of New York in wagons drawn by oxen
to the remote and primitive township of Bayfield, in Upper Canada, on

great-grandfather of Thomas Alva, reached the extreme old age of 104
years. But all was not well, and, as has happened so often before, the
politics of father and son were violently different. The Loyalist movement
that took to Nova Scotia so many Americans after the War of Independence
carried with it John, the son of this stalwart Continental. Thus it came about
that Samuel Edison, son of John, was born at Digby, Nova Scotia, in 1804.
Seven years later John Edison who, as a Loyalist or United Empire
emigrant, had become entitled under the laws of Canada to a grant of six
hundred acres of land, moved westward to take possession of this property.
He made his way through the State of New York in wagons drawn by oxen
to the remote and primitive township of Bayfield, in Upper Canada, on
Page 20
Lake Huron. Although the journey occurred in balmy June, it was
necessarily attended with difficulty and privation; but the new home was
situated in good farming country, and once again this interesting nomadic
family settled down.
John Edison moved from Bayfield to Vienna, Ontario, on the northern
bank of Lake Erie. Mr. Edison supplies an interesting reminiscence of the
old man and his environment in those early Canadian days. "When I was
five years old I was taken by my father and mother on a visit to Vienna. We
were driven by carriage from Milan, Ohio, to a railroad, then to a port on
Lake Erie, thence by a canal-boat in a tow of several to Port Burwell, in
Canada, across the lake, and from there we drove to Vienna, a short distance
away. I remember my grandfather perfectly as he appeared, at 102 years of
age, when he died. In the middle of the day he sat under a large tree in front
of the house facing a well-travelled road. His head was covered completely
with a large quantity of very white hair, and he chewed tobacco incessantly,
nodding to friends as they passed by. He used a very large cane, and walked
from the chair to the house, resenting any assistance. I viewed him from a
distance, and could never get very close to him. I remember some large
pipes, and especially a molasses jug, a trunk, and several other things that
came from Holland."
John Edison was long-lived, like his father, and reached the ripe old age
of 102, leaving his son Samuel charged with the care of the family
destinies, but with no great burden of wealth. Little is known of the early
manhood of this father of T. A. Edison until we find him keeping a hotel at
Vienna, marrying a school-teacher there (Miss Nancy Elliott, in 1828), and
taking a lively share in the troublous politics of the time. He was six feet in
height, of great bodily vigor, and of such personal dominance of character
that he became a captain of the insurgent forces rallying under the banners
of Papineau and Mackenzie. The opening years of Queen Victoria's reign
witnessed a belated effort in Canada to emphasize the principle that there
should not be taxation without representation; and this descendant of those
who had left the United States from disapproval of such a doctrine, flung
himself headlong into its support.
It has been said of Earl Durham, who pacified Canada at this time and
established the present system of government, that he made a country and
marred a career. But the immediate measures of repression enforced before
necessarily attended with difficulty and privation; but the new home was
situated in good farming country, and once again this interesting nomadic

It has been said of Earl Durham, who pacified Canada at this time and

Page 21
a liberal policy was adopted were sharp and severe, and Samuel Edison also
found his own career marred on Canadian soil as one result of the Durham
administration. Exile to Bermuda with other insurgents was not so attractive
as the perils of a flight to the United States. A very hurried departure was
effected in secret from the scene of trouble, and there are romantic
traditions of his thrilling journey of one hundred and eighty-two miles
toward safety, made almost entirely without food or sleep, through a wild
country infested with Indians of unfriendly disposition. Thus was the
Edison family repatriated by a picturesque political episode, and the great
inventor given a birthplace on American soil, just as was Benjamin Franklin
when his father came from England to Boston. Samuel Edison left behind
him, however, in Canada, several brothers, all of whom lived to the age of
ninety or more, and from whom there are descendants in the region.
After some desultory wanderings for a year or two along the shores of
Lake Erie, among the prosperous towns then springing up, the family, with
its Canadian home forfeited, and in quest of another resting-place, came to
Milan, Ohio, in 1842. That pretty little village offered at the moment many
attractions as a possible Chicago. The railroad system of Ohio was still in
the future, but the Western Reserve had already become a vast wheat-field,
and huge quantities of grain from the central and northern counties sought
shipment to Eastern ports. The Huron River, emptying into Lake Erie, was
navigable within a few miles of the village, and provided an admirable
outlet. Large granaries were established, and proved so successful that local
capital was tempted into the project of making a tow-path canal from
Lockwood Landing all the way to Milan itself. The quaint old Moravian
mission and quondam Indian settlement of one hundred inhabitants found
itself of a sudden one of the great grain ports of the world, and bidding fair
to rival Russian Odessa. A number of grain warehouses, or primitive
elevators, were built along the bank of the canal, and the produce of the
region poured in immediately, arriving in wagons drawn by four or six
horses with loads of a hundred bushels. No fewer than six hundred wagons
came clattering in, and as many as twenty sail vessels were loaded with
thirty-five thousand bushels of grain, during a single day. The canal was
capable of being navigated by craft of from two hundred to two hundred
and fifty tons burden, and the demand for such vessels soon led to the
development of a brisk ship-building industry, for which the abundant
forests of the region supplied the necessary lumber. An evidence of the

development of a brisk ship-building industry, for which the abundant
forests of the region supplied the necessary lumber. An evidence of the
Page 22
activity in this direction is furnished by the fact that six revenue cutters
were launched at this port in these brisk days of its prime.
Samuel Edison, versatile, buoyant of temper, and ever optimistic, would
thus appear to have pitched his tent with shrewd judgment. There was
plenty of occupation ready to his hand, and more than one enterprise
received his attention; but he devoted his energies chiefly to the making of
shingles, for which there was a large demand locally and along the lake.
Canadian lumber was used principally in this industry. The wood was
imported in "bolts" or pieces three feet long. A bolt made two shingles; it
was sawn asunder by hand, then split and shaved. None but first-class
timber was used, and such shingles outlasted far those made by machinery
with their cross-grain cut. A house in Milan, on which some of those
shingles were put in 1844, was still in excellent condition forty-two years
later. Samuel Edison did well at this occupation, and employed several men,
but there were other outlets from time to time for his business activity and
speculative disposition.
Edison's mother was an attractive and highly educated woman, whose
influence upon his disposition and intellect has been profound and lasting.
She was born in Chenango County, New York, in 1810, and was the
daughter of the Rev. John Elliott, a Baptist minister and descendant of an
old Revolutionary soldier, Capt. Ebenezer Elliott, of Scotch descent. The
old captain was a fine and picturesque type. He fought all through the long
War of Independence—seven years—and then appears to have settled down
at Stonington, Connecticut. There, at any rate, he found his wife,
"grandmother Elliott," who was Mercy Peckham, daughter of a Scotch
Quaker. Then came the residence in New York State, with final removal to
Vienna, for the old soldier, while drawing his pension at Buffalo, lived in
the little Canadian town, and there died, over 100 years old. The family was
evidently one of considerable culture and deep religious feeling, for two of
Mrs. Edison's uncles and two brothers were also in the same Baptist
ministry. As a young woman she became a teacher in the public high school
at Vienna, and thus met her husband, who was residing there. The family
never consisted of more than three children, two boys and a girl. A trace of
the Canadian environment is seen in the fact that Edison's elder brother was
named William Pitt, after the great English statesman. Both his brother and
the sister exhibited considerable ability. William Pitt Edison as a youth was
so clever with his pencil that it was proposed to send him to Paris as an art

so clever with his pencil that it was proposed to send him to Paris as an art
Page 23
student. In later life he was manager of the local street railway lines at Port
Huron, Michigan, in which he was heavily interested. He also owned a
good farm near that town, and during the ill-health at the close of his life,
when compelled to spend much of the time indoors, he devoted himself
almost entirely to sketching. It has been noted by intimate observers of
Thomas A. Edison that in discussing any project or new idea his first
impulse is to take up any piece of paper available and make drawings of it.
His voluminous note-books are a mass of sketches. Mrs-Tannie Edison
Bailey, the sister, had, on the other hand, a great deal of literary ability, and
spent much of her time in writing.
The great inventor, whose iron endurance and stern will have enabled
him to wear down all his associates by work sustained through arduous
days and sleepless nights, was not at all strong as a child, and was of fragile
appearance. He had an abnormally large but well-shaped head, and it is said
that the local doctors feared he might have brain trouble. In fact, on account
of his assumed delicacy, he was not allowed to go to school for some years,
and even when he did attend for a short time the results were not
encouraging—his mother being hotly indignant upon hearing that the
teacher had spoken of him to an inspector as "addled." The youth was,
indeed, fortunate far beyond the ordinary in having a mother at once loving,
well-informed, and ambitious, capable herself, from her experience as a
teacher, of undertaking and giving him an education better than could be
secured in the local schools of the day. Certain it is that under this simple
regime studious habits were formed and a taste for literature developed that
have lasted to this day. If ever there was a man who tore the heart out of
books it is Edison, and what has once been read by him is never forgotten if
useful or worthy of submission to the test of experiment.
But even thus early the stronger love of mechanical processes and of
probing natural forces manifested itself. Edison has said that he never saw a
statement in any book as to such things that he did not involuntarily
challenge, and wish to demonstrate as either right or wrong. As a mere child
the busy scenes of the canal and the grain warehouses were of consuming
interest, but the work in the ship-building yards had an irresistible
fascination. His questions were so ceaseless and innumerable that the
penetrating curiosity of an unusually strong mind was regarded as
deficiency in powers of comprehension, and the father himself, a man of no
mean ingenuity and ability, reports that the child, although capable of

deficiency in powers of comprehension, and the father himself, a man of no
mean ingenuity and ability, reports that the child, although capable of
Page 24
reducing him to exhaustion by endless inquiries, was often spoken of as
rather wanting in ordinary acumen. This apparent dulness is, however, a
quite common incident to youthful genius.
The constructive tendencies of this child of whom his father said once
that he had never had any boyhood days in the ordinary sense, were early
noted in his fondness for building little plank roads out of the debris of the
yards and mills. His extraordinarily retentive memory was shown in his
easy acquisition of all the songs of the lumber gangs and canal men before
he was five years old. One incident tells how he was found one day in the
village square copying laboriously the signs of the stores. A highly
characteristic event at the age of six is described by his sister. He had noted
a goose sitting on her eggs and the result. One day soon after, he was
missing. By-and-by, after an anxious search, his father found him sitting in
a nest he had made in the barn, filled with goose-eggs and hens' eggs he had
collected, trying to hatch them out.
One of Mr. Edison's most vivid recollections goes back to 1850, when as
a child three of four years old he saw camped in front of his home six
covered wagons, "prairie schooners," and witnessed their departure for
California. The great excitement over the gold discoveries was thus felt in
Milan, and these wagons, laden with all the worldly possessions of their
owners, were watched out of sight on their long journey by this fascinated
urchin, whose own discoveries in later years were to tempt many other
argonauts into the auriferous realms of electricity.
Another vivid memory of this period concerns his first realization of the
grim mystery of death. He went off one day with the son of the wealthiest
man in the town to bathe in the creek. Soon after they entered the water the
other boy disappeared. Young Edison waited around the spot for half an
hour or more, and then, as it was growing dark, went home puzzled and
lonely, but silent as to the occurrence. About two hours afterward, when the
missing boy was being searched for, a man came to the Edison home to
make anxious inquiry of the companion with whom he had last been seen.
Edison told all the circumstances with a painful sense of being in some way
implicated. The creek was at once dragged, and then the body was
recovered.
Edison had himself more than one narrow escape. Of course he fell in the
canal and was nearly drowned; few boys in Milan worth their salt omitted
rather wanting in ordinary acumen. This apparent dulness is, however, a
quite common incident to youthful genius.

Edison had himself more than one narrow escape. Of course he fell in the
canal and was nearly drowned; few boys in Milan worth their salt omitted
Page 25
that performance. On another occasion he encountered a more novel peril
by falling into the pile of wheat in a grain elevator and being almost
smothered. Holding the end of a skate-strap for another lad to shorten with
an axe, he lost the top of a finger. Fire also had its perils. He built a fire in a
barn, but the flames spread so rapidly that, although he escaped himself, the
barn was wholly destroyed, and he was publicly whipped in the village
square as a warning to other youths. Equally well remembered is a
dangerous encounter with a ram that attacked him while he was busily
engaged digging out a bumblebee's nest near an orchard fence. The animal
knocked him against the fence, and was about to butt him again when he
managed to drop over on the safe side and escape. He was badly hurt and
bruised, and no small quantity of arnica was needed for his wounds.
Meantime little Milan had reached the zenith of its prosperity, and all of a
sudden had been deprived of its flourishing grain trade by the new
Columbus, Sandusky & Hocking Railroad; in fact, the short canal was one
of the last efforts of its kind in this country to compete with the new means
of transportation. The bell of the locomotive was everywhere ringing the
death-knell of effective water haulage, with such dire results that, in 1880,
of the 4468 miles of American freight canal, that had cost $214,000,000, no
fewer than 1893 miles had been abandoned, and of the remaining 2575
miles quite a large proportion was not paying expenses. The short Milan
canal suffered with the rest, and to-day lies well-nigh obliterated, hidden in
part by vegetable gardens, a mere grass-grown depression at the foot of the
winding, shallow valley. Other railroads also prevented any further
competition by the canal, for a branch of the Wheeling & Lake Erie now
passes through the village, while the Lake Shore & Michigan Southern runs
a few miles to the south.
The owners of the canal soon had occasion to regret that they had
disdained the overtures of enterprising railroad promoters desirous of
reaching the village, and the consequences of commercial isolation rapidly
made themselves felt. It soon became evident to Samuel Edison and his
wife that the cozy brick home on the bluff must be given up and the
struggle with fortune resumed elsewhere. They were well-to-do, however,
and removing, in 1854, to Port Huron, Michigan, occupied a large colonial
house standing in the middle of an old Government fort reservation of ten
acres overlooking the wide expanse of the St. Clair River just after it leaves
Lake Huron. It was in many ways an ideal homestead, toward which the
by falling into the pile of wheat in a grain elevator and being almost
smothered. Holding the end of a skate-strap for another lad to shorten with
an axe, he lost the top of a finger. Fire also had its perils. He built a fire in a
barn, but the flames spread so rapidly that, although he escaped himself, the
barn was wholly destroyed, and he was publicly whipped in the village
square as a warning to other youths. Equally well remembered is a
dangerous encounter with a ram that attacked him while he was busily
engaged digging out a bumblebee's nest near an orchard fence. The animal
knocked him against the fence, and was about to butt him again when he
managed to drop over on the safe side and escape. He was badly hurt and
bruised, and no small quantity of arnica was needed for his wounds.
Meantime little Milan had reached the zenith of its prosperity, and all of a
sudden had been deprived of its flourishing grain trade by the new
Columbus, Sandusky & Hocking Railroad; in fact, the short canal was one
of the last efforts of its kind in this country to compete with the new means
of transportation. The bell of the locomotive was everywhere ringing the
death-knell of effective water haulage, with such dire results that, in 1880,
of the 4468 miles of American freight canal, that had cost $214,000,000, no
fewer than 1893 miles had been abandoned, and of the remaining 2575
miles quite a large proportion was not paying expenses. The short Milan

house standing in the middle of an old Government fort reservation of ten
acres overlooking the wide expanse of the St. Clair River just after it leaves
Lake Huron. It was in many ways an ideal homestead, toward which the
Page 26
family has always felt the strongest attachment, but the association with
Milan has never wholly ceased. The old house in which Edison was born is
still occupied (in 1910) by Mr. S. O. Edison, a half-brother of Edison's
father, and a man of marked inventive ability. He was once prominent in the
iron-furnace industry of Ohio, and was for a time associated in the iron
trade with the father of the late President McKinley. Among his inventions
may be mentioned a machine for making fuel from wheat straw, and a
smoke-consuming device.
This birthplace of Edison remains the plain, substantial little brick house
it was originally: one-storied, with rooms finished on the attic floor. Being
built on the hillside, its basement opens into the rear yard. It was at first
heated by means of open coal grates, which may not have been altogether
adequate in severe winters, owing to the altitude and the north-eastern
exposure, but a large furnace is one of the more modern changes. Milan
itself is not materially unlike the smaller Ohio towns of its own time or
those of later creation, but the venerable appearance of the big elm-trees
that fringe the trim lawns tells of its age. It is, indeed, an extremely neat,
snug little place, with well-kept homes, mostly of frame construction, and
flagged streets crossing each other at right angles. There are no poor—at
least, everybody is apparently well-to-do. While a leisurely atmosphere
pervades the town, few idlers are seen. Some of the residents are engaged in
local business; some are occupied in farming and grape culture; others are
employed in the iron-works near-by, at Norwalk. The stores and places of
public resort are gathered about the square, where there is plenty of room
for hitching when the Saturday trading is done at that point, at which
periods the fitful bustle recalls the old wheat days when young Edison ran
with curiosity among the six and eight horse teams that had brought in
grain. This square is still covered with fine primeval forest trees, and has at
its centre a handsome soldiers' monument of the Civil War, to which four
paved walks converge. It is an altogether pleasant and unpretentious town,
which cherishes with no small amount of pride its association with the
name of Thomas Alva Edison.
In view of Edison's Dutch descent, it is rather singular to find him with
the name of Alva, for the Spanish Duke of Alva was notoriously the worst
tyrant ever known to the Low Countries, and his evil deeds occupy many
stirring pages in Motley's famous history. As a matter of fact, Edison was
named after Capt. Alva Bradley, an old friend of his father, and a celebrated

CHAPTER III
BOYHOOD AT PORT HURON, MICHIGAN
THE new home found by the Edison family at Port Huron, where Alva
spent his brief boyhood before he became a telegraph operator and roamed
the whole middle West of that period, was unfortunately destroyed by fire
just after the close of the Civil War. A smaller but perhaps more comfortable
home was then built by Edison's father on some property he had bought at
the near-by village of Gratiot, and there his mother spent the remainder of
her life in confirmed invalidism, dying in 1871. Hence the pictures and
postal cards sold largely to souvenir-hunters as the Port Huron home do not
actually show that in or around which the events now referred to took place.
It has been a romance of popular biographers, based upon the fact that
Edison began his career as a newsboy, to assume that these earlier years
were spent in poverty and privation, as indeed they usually are by the
"newsies" who swarm and shout their papers in our large cities. While it
seems a pity to destroy this erroneous idea, suggestive of a heroic climb
from the depths to the heights, nothing could be further from the truth.
Socially the Edison family stood high in Port Huron at a time when there
was relatively more wealth and general activity than to-day. The town in its
pristine prime was a great lumber centre, and hummed with the industry of
numerous sawmills. An incredible quantity of lumber was made there
yearly until the forests near-by vanished and the industry with them. The
wealth of the community, invested largely in this business and in allied
transportation companies, was accumulated rapidly and as freely spent
during those days of prosperity in St. Clair County, bringing with it a high
standard of domestic comfort. In all this the Edisons shared on equal terms.
Thus, contrary to the stories that have been so widely published, the
Edisons, while not rich by any means, were in comfortable circumstances,
with a well-stocked farm and large orchard to draw upon also for
sustenance. Samuel Edison, on moving to Port Huron, became a dealer in
grain and feed, and gave attention to that business for many years. But he
was also active in the lumber industry in the Saginaw district and several

Thus, contrary to the stories that have been so widely published, the

sustenance. Samuel Edison, on moving to Port Huron, became a dealer in
grain and feed, and gave attention to that business for many years. But he
was also active in the lumber industry in the Saginaw district and several
Page 29
other things. It was difficult for a man of such mercurial, restless
temperament to stay constant to any one occupation; in fact, had he been
less visionary he would have been more prosperous, but might not have had
a son so gifted with insight and imagination. One instance of the optimistic
vagaries which led him incessantly to spend time and money on projects
that would not have appealed to a man less sanguine was the construction
on his property of a wooden observation tower over a hundred feet high, the
top of which was reached toilsomely by winding stairs, after the payment of
twenty-five cents. It is true that the tower commanded a pretty view by land
and water, but Colonel Sellers himself might have projected this enterprise
as a possible source of steady income. At first few visitors panted up the
long flights of steps to the breezy platform. During the first two months
Edison's father took in three dollars, and felt extremely blue over the
prospect, and to young Edison and his relatives were left the lonely
pleasures of the lookout and the enjoyment of the telescope with which it
was equipped. But one fine day there came an excursion from an inland
town to see the lake. They picnicked in the grove, and six hundred of them
went up the tower. After that the railroad company began to advertise these
excursions, and the receipts each year paid for the observatory.
It might be thought that, immersed in business and preoccupied with
schemes of this character, Mr. Edison was to blame for the neglect of his
son's education. But that was not the case. The conditions were peculiar. It
was at the Port Huron public school that Edison received all the regular
scholastic instruction he ever enjoyed—just three months. He might have
spent the full term there, but, as already noted, his teacher had found him
"addled." He was always, according to his own recollection, at the foot of
the class, and had come almost to regard himself as a dunce, while his
father entertained vague anxieties as to his stupidity. The truth of the matter
seems to be that Mrs. Edison, a teacher of uncommon ability and force, held
no very high opinion of the average public-school methods and results, and
was both eager to undertake the instruction of her son and ambitious for the
future of a boy whom she knew from pedagogic experience to be receptive
and thoughtful to a very unusual degree. With her he found study easy and
pleasant. The quality of culture in that simple but refined home, as well as
the intellectual character of this youth without schooling, may be inferred
from the fact that before he had reached the age of twelve he had read, with
his mother's help, Gibbon's Decline and Fall of the Roman Empire, Hume's
temperament to stay constant to any one occupation; in fact, had he been
less visionary he would have been more prosperous, but might not have had

Page 30
History of England, Sears' History of the World, Burton's Anatomy of
Melancholy, and the Dictionary of Sciences; and had even attempted to
struggle through Newton's Principia, whose mathematics were decidedly
beyond both teacher and student. Besides, Edison, like Faraday, was never a
mathematician, and has had little personal use for arithmetic beyond that
which is called "mental." He said once to a friend: "I can always hire some
mathematicians, but they can't hire me." His father, by-the-way, always
encouraged these literary tastes, and paid him a small sum for each new
book mastered. It will be noted that fiction makes no showing in the list; but
it was not altogether excluded from the home library, and Edison has all his
life enjoyed it, particularly the works of such writers as Victor Hugo, after
whom, because of his enthusiastic admiration—possibly also because of his
imagination—he was nicknamed by his fellow-operators, "Victor Hugo
Edison."
Electricity at that moment could have no allure for a youthful mind.
Crude telegraphy represented what was known of it practically, and about
that the books read by young Edison were not redundantly informational.
Even had that not been so, the inclinations of the boy barely ten years old
were toward chemistry, and fifty years later there is seen no change of
predilection. It sounds like heresy to say that Edison became an electrician
by chance, but it is the sober fact that to this pre-eminent and brilliant leader
in electrical achievement escape into the chemical domain still has the
aspect of a delightful truant holiday. One of the earliest stories about his
boyhood relates to the incident when he induced a lad employed in the
family to swallow a large quantity of Seidlitz powders in the belief that the
gases generated would enable him to fly. The agonies of the victim attracted
attention, and Edison's mother marked her displeasure by an application of
the switch kept behind the old Seth Thomas "grandfather clock." The
disastrous result of this experiment did not discourage Edison at all, as he
attributed failure to the lad rather than to the motive power. In the cellar of
the Edison homestead young Alva soon accumulated a chemical outfit,
constituting the first in a long series of laboratories. The word "laboratory"
had always been associated with alchemists in the past, but as with
"filament" this untutored stripling applied an iconoclastic practicability to it
long before he realized the significance of the new departure. Goethe, in his
legend of Faust, shows the traditional or conventional philosopher in his
laboratory, an aged, tottering, gray-bearded investigator, who only becomes
Melancholy, and the Dictionary of Sciences; and had even attempted to
struggle through Newton's Principia, whose mathematics were decidedly

Page 31
youthful upon diabolical intervention, and would stay senile without it. In
the Edison laboratory no such weird transformation has been necessary, for
the philosopher had youth, fiery energy, and a grimly practical
determination that would submit to no denial of the goal of something of
real benefit to mankind. Edison and Faust are indeed the extremes of
philosophic thought and accomplishment.
The home at Port Huron thus saw the first Edison laboratory. The boy
began experimenting when he was about ten or eleven years of age. He got
a copy of Parker's School Philosophy, an elementary book on physics, and
about every experiment in it he tried. Young Alva, or "Al," as he was called,
thus early displayed his great passion for chemistry, and in the cellar of the
house he collected no fewer than two hundred bottles, gleaned in baskets
from all parts of the town. These were arranged carefully on shelves and all
labelled "Poison," so that no one else would handle or disturb them. They
contained the chemicals with which he was constantly experimenting. To
others this diversion was both mysterious and meaningless, but he had soon
become familiar with all the chemicals obtainable at the local drug stores,
and had tested to his satisfaction many of the statements encountered in his
scientific reading. Edison has said that sometimes he has wondered how it
was he did not become an analytical chemist instead of concentrating on
electricity, for which he had at first no great inclination.
Deprived of the use of a large part of her cellar, tiring of the "mess"
always to be found there, and somewhat fearful of results, his mother once
told the boy to clear everything out and restore order. The thought of losing
all his possessions was the cause of so much ardent distress that his mother
relented, but insisted that he must get a lock and key, and keep the
embryonic laboratory closed up all the time except when he was there. This
was done. From such work came an early familiarity with the nature of
electrical batteries and the production of current from them. Apparently the
greater part of his spare time was spent in the cellar, for he did not share to
any extent in the sports of the boys of the neighborhood, his chum and chief
companion, Michael Oates, being a lad of Dutch origin, many years older,
who did chores around the house, and who could be recruited as a general
utility Friday for the experiments of this young explorer—such as that with
the Seidlitz powders.

Such pursuits as these consumed the scant pocket-money of the boy very
rapidly. He was not in regular attendance at school, and had read all the
books within reach. It was thus he turned newsboy, overcoming the
reluctance of his parents, particularly that of his mother, by pointing out that
he could by this means earn all he wanted for his experiments and get fresh
reading in the shape of papers and magazines free of charge. Besides, his
leisure hours in Detroit he would be able to spend at the public library. He
applied (in 1859) for the privilege of selling newspapers on the trains of the
Grand Trunk Railroad, between Port Huron and Detroit, and obtained the
concession after a short delay, during which he made an essay in his task of
selling newspapers.
Edison had, as a fact, already had some commercial experience from the
age of eleven. The ten acres of the reservation offered an excellent
opportunity for truck-farming, and the versatile head of the family could not
avoid trying his luck in this branch of work. A large "market garden" was
laid out, in which Edison worked pretty steadily with the help of the Dutch
boy, Michael Oates—he of the flying experiment. These boys had a horse
and small wagon intrusted to them, and every morning in the season they
would load up with onions, lettuce, peas, etc., and go through the town.
As much as $600 was turned over to Mrs. Edison in one year from this
source. The boy was indefatigable but not altogether charmed with
agriculture. "After a while I tired of this work, as hoeing corn in a hot sun is
unattractive, and I did not wonder that it had built up cities. Soon the Grand
Trunk Railroad was extended from Toronto to Port Huron, at the foot of
Lake Huron, and thence to Detroit, at about the same time the War of the
Rebellion broke out. By a great amount of persistence I got permission from
my mother to go on the local train as a newsboy. The local train from Port
Huron to Detroit, a distance of sixty-three miles, left at 7 A.M. and arrived
again at 9.30 P.M. After being on the train for several months, I started two
stores in Port Huron—one for periodicals, and the other for vegetables,
butter, and berries in the season. These were attended by two boys who
shared in the profits. The periodical store I soon closed, as the boy in charge
could not be trusted. The vegetable store I kept up for nearly a year. After
the railroad had been opened a short time, they put on an express which left
Detroit in the morning and returned in the evening. I received permission to
put a newsboy on this train. Connected with this train was a car, one part for
baggage and the other part for U. S. mail, but for a long time it was not
rapidly. He was not in regular attendance at school, and had read all the
books within reach. It was thus he turned newsboy, overcoming the
reluctance of his parents, particularly that of his mother, by pointing out that
he could by this means earn all he wanted for his experiments and get fresh

put a newsboy on this train. Connected with this train was a car, one part for
baggage and the other part for U. S. mail, but for a long time it was not
Page 33
used. Every morning I had two large baskets of vegetables from the Detroit
market loaded in the mail-car and sent to Port Huron, where the boy would
take them to the store. They were much better than those grown locally, and
sold readily. I never was asked to pay freight, and to this day cannot explain
why, except that I was so small and industrious, and the nerve to
appropriate a U. S. mail-car to do a free freight business was so
monumental. However, I kept this up for a long time, and in addition
bought butter from the farmers along the line, and an immense amount of
blackberries in the season. I bought wholesale and at a low price, and
permitted the wives of the engineers and trainmen to have the benefit of the
discount. After a while there was a daily immigrant train put on. This train
generally had from seven to ten coaches filled always with Norwegians, all
bound for Iowa and Minnesota. On these trains I employed a boy who sold
bread, tobacco, and stick candy. As the war progressed the daily newspaper
sales became very profitable, and I gave up the vegetable store."
The hours of this occupation were long, but the work was not particularly
heavy, and Edison soon found opportunity for his favorite avocation—
chemical experimentation. His train left Port Huron at 7 A.M., and made its
southward trip to Detroit in about three hours. This gave a stay in that city
from 10 A.M. until the late afternoon, when the train left, arriving at Port
Huron about 9.30 P.M. The train was made up of three coaches—baggage,
smoking, and ordinary passenger or "ladies." The baggage-car was divided
into three compartments—one for trunks and packages, one for the mail,
and one for smoking. In those days no use was made of the smoking-
compartment, as there was no ventilation, and it was turned over to young
Edison, who not only kept papers there and his stock of goods as a "candy
butcher," but soon had it equipped with an extraordinary variety of
apparatus. There was plenty of leisure on the two daily runs, even for an
industrious boy, and thus he found time to transfer his laboratory from the
cellar and re-establish it on the train.
His earnings were also excellent—so good, in fact, that eight or ten
dollars a day were often taken in, and one dollar went every day to his
mother. Thus supporting himself, he felt entitled to spend any other profit
left over on chemicals and apparatus. And spent it was, for with access to
Detroit and its large stores, where he bought his supplies, and to the public
library, where he could quench his thirst for technical information, Edison
gave up all his spare time and money to chemistry. Surely the country could

Page 34
have presented at that moment no more striking example of the passionate
pursuit of knowledge under difficulties than this newsboy, barely fourteen
years of age, with his jars and test-tubes installed on a railway baggage-car.
Nor did this amazing equipment stop at batteries and bottles. The same
little space a few feet square was soon converted by this precocious youth
into a newspaper office. The outbreak of the Civil War gave a great stimulus
to the demand for all newspapers, noticing which he became ambitious to
publish a local journal of his own, devoted to the news of that section of the
Grand Trunk road. A small printing-press that had been used for hotel bills
of fare was picked up in Detroit, and type was also bought, some of it being
placed on the train so that composition could go on in spells of leisure. To
one so mechanical in his tastes as Edison, it was quite easy to learn the
rudiments of the printing art, and thus the Weekly Herald came into
existence, of which he was compositor, pressman, editor, publisher, and
newsdealer. Only one or two copies of this journal are now discoverable,
but its appearance can be judged from the reduced facsimile here shown.
The thing was indeed well done as the work of a youth shown by the date to
be less than fifteen years old. The literary style is good, there are only a few
trivial slips in spelling, and the appreciation is keen of what would be
interesting news and gossip. The price was three cents a copy, or eight cents
a month for regular subscribers, and the circulation ran up to over four
hundred copies an issue. This was by no means the result of mere public
curiosity, but attested the value of the sheet as a genuine newspaper, to
which many persons in the railroad service along the line were willing
contributors. Indeed, with the aid of the railway telegraph, Edison was often
able to print late news of importance, of local origin, that the distant regular
papers like those of Detroit, which he handled as a newsboy, could not get.
It is no wonder that this clever little sheet received the approval and
patronage of the English engineer Stephenson when inspecting the Grand
Trunk system, and was noted by no less distinguished a contemporary than
the London Times as the first newspaper in the world to be printed on a
train in motion. The youthful proprietor sometimes cleared as much as
twenty to thirty dollars a month from this unique journalistic enterprise.
But all this extra work required attention, and Edison solved the difficulty
of attending also to the newsboy business by the employment of a young
friend, whom he trained and treated liberally as an understudy. There was
often plenty of work for both in the early days of the war, when the news of
pursuit of knowledge under difficulties than this newsboy, barely fourteen

friend, whom he trained and treated liberally as an understudy. There was
often plenty of work for both in the early days of the war, when the news of
Page 35
battle caused intense excitement and large sales of papers. Edison, with
native shrewdness already so strikingly displayed, would telegraph the
station agents and get them to bulletin the event of the day at the front, so
that when each station was reached there were eager purchasers waiting. He
recalls in particular the sensation caused by the great battle of Shiloh, or
Pittsburg Landing, in April, 1862, in which both Grant and Sherman were
engaged, in which Johnston died, and in which there was a ghastly total of
25,000 killed and wounded.
In describing his enterprising action that day, Edison says that when he
reached Detroit the bulletin-boards of the newspaper offices were
surrounded with dense crowds, which read awestricken the news that there
were 60,000 killed and wounded, and that the result was uncertain. "I knew
that if the same excitement was attained at the various small towns along
the road, and especially at Port Huron, the sale of papers would be great. I
then conceived the idea of telegraphing the news ahead, went to the
operator in the depot, and by giving him Harper's Weekly and some other
papers for three months, he agreed to telegraph to all the stations the matter
on the bulletin-board. I hurriedly copied it, and he sent it, requesting the
agents to display it on the blackboards used for stating the arrival and
departure of trains. I decided that instead of the usual one hundred papers I
could sell one thousand; but not having sufficient money to purchase that
number, I determined in my desperation to see the editor himself and get
credit. The great paper at that time was the Detroit Free Press. I walked into
the office marked 'Editorial' and told a young man that I wanted to see the
editor on important business—important to me, anyway, I was taken into an
office where there were two men, and I stated what I had done about
telegraphing, and that I wanted a thousand papers, but only had money for
three hundred, and I wanted credit. One of the men refused it, but the other
told the first spokesman to let me have them. This man, I afterward learned,
was Wilbur F. Storey, who subsequently founded the Chicago Times, and
became celebrated in the newspaper world. By the aid of another boy I
lugged the papers to the train and started folding them. The first station,
called Utica, was a small one where I generally sold two papers. I saw a
crowd ahead on the platform, and thought it some excursion, but the
moment I landed there was a rush for me; then I realized that the telegraph
was a great invention. I sold thirty-five papers there. The next station was
Mount Clemens, now a watering-place, but then a town of about one

Page 36
thousand. I usually sold six to eight papers there. I decided that if I found a
corresponding crowd there, the only thing to do to correct my lack of
judgment in not getting more papers was to raise the price from five cents
to ten. The crowd was there, and I raised the price. At the various towns
there were corresponding crowds. It had been my practice at Port Huron to
jump from the train at a point about one-fourth of a mile from the station,
where the train generally slackened speed. I had drawn several loads of
sand to this point to jump on, and had become quite expert. The little Dutch
boy with the horse met me at this point. When the wagon approached the
outskirts of the town I was met by a large crowd. I then yelled: 'Twenty-five
cents apiece, gentlemen! I haven't enough to go around!' I sold all out, and
made what to me then was an immense sum of money."
Such episodes as this added materially to his income, but did not
necessarily increase his savings, for he was then, as now, an utter
spendthrift so long as some new apparatus or supplies for experiment could
be had. In fact, the laboratory on wheels soon became crowded with such
equipment, most costly chemicals were bought on the instalment plan, and
Fresenius' Qualitative Analysis served as a basis for ceaseless testing and
study. George Pullman, who then had a small shop at Detroit and was
working on his sleeping-car, made Edison a lot of wooden apparatus for his
chemicals, to the boy's delight. Unfortunately a sudden change came,
fraught with disaster. The train, running one day at thirty miles an hour over
a piece of poorly laid track, was thrown suddenly out of the perpendicular
with a violent lurch, and, before Edison could catch it, a stick of phosphorus
was jarred from its shelf, fell to the floor, and burst into flame. The car took
fire, and the boy, in dismay, was still trying to quench the blaze when the
conductor, a quick-tempered Scotchman, who acted also as baggage-master,
hastened to the scene with water and saved his car. On the arrival at Mount
Clemens station, its next stop, Edison and his entire outfit, laboratory,
printing-plant, and all, were promptly ejected by the enraged conductor, and
the train then moved off, leaving him on the platform, tearful and indignant
in the midst of his beloved but ruined possessions. It was lynch law of a
kind; but in view of the responsibility, this action of the conductor lay well
within his rights and duties.
It was through this incident that Edison acquired the deafness that has
persisted all through his life, a severe box on the ears from the scorched and
angry conductor being the direct cause of the infirmity. Although this
corresponding crowd there, the only thing to do to correct my lack of
judgment in not getting more papers was to raise the price from five cents
to ten. The crowd was there, and I raised the price. At the various towns

angry conductor being the direct cause of the infirmity. Although this
Page 37
deafness would be regarded as a great affliction by most people, and has
brought in its train other serious baubles, Mr. Edison has always regarded it
philosophically, and said about it recently: "This deafness has been of great
advantage to me in various ways. When in a telegraph office, I could only
hear the instrument directly on the table at which I sat, and unlike the other
operators, I was not bothered by the other instruments. Again, in
experimenting on the telephone, I had to improve the transmitter so I could
hear it. This made the telephone commercial, as the magneto telephone
receiver of Bell was too weak to be used as a transmitter commercially. It
was the same with the phonograph. The great defect of that instrument was
the rendering of the overtones in music, and the hissing consonants in
speech. I worked over one year, twenty hours a day, Sundays and all, to get
the word 'specie' perfectly recorded and reproduced on the phonograph.
When this was done I knew that everything else could be done which was a
fact. Again, my nerves have been preserved intact. Broadway is as quiet to
me as a country village is to a person with normal hearing."
Saddened but not wholly discouraged, Edison soon reconstituted his
laboratory and printing-office at home, although on the part of the family
there was some fear and objection after this episode, on the score of fire.
But Edison promised not to bring in anything of a dangerous nature. He did
not cease the publication of the Weekly Herald. On the contrary, he
prospered in both his enterprises until persuaded by the "printer's devil" in
the office of the Port Huron Commercial to change the character of his
journal, enlarge it, and issue it under the name of Paul Pry, a happy
designation for this or kindred ventures in the domain of society journalism.
No copies of Paul Pry can now be found, but it is known that its style was
distinctly personal, that gossip was its specialty, and that no small offence
was given to the people whose peculiarities or peccadilloes were discussed
in a frank and breezy style by the two boys. In one instance the resentment
of the victim of such unsought publicity was so intense he laid hands on
Edison and pitched the startled young editor into the St. Clair River. The
name of this violator of the freedom of the press was thereafter excluded
studiously from the columns of Paul Pry, and the incident may have been
one of those which soon caused the abandonment of the paper. Edison had
great zest in this work, and but for the strong influences in other directions
would probably have continued in the newspaper field, in which he was,
beyond question, the youngest publisher and editor of the day.

Before leaving this period of his career, it is to be noted that it gave
Edison many favorable opportunities. In Detroit he could spend frequent
hours in the public library, and it is matter of record that he began his liberal
acquaintance with its contents by grappling bravely with a certain section
and trying to read it through consecutively, shelf by shelf, regardless of
subject. In a way this is curiously suggestive of the earnest, energetic
method of "frontal attack" with which the inventor has since addressed
himself to so many problems in the arts and sciences.
The Grand Trunk Railroad machine-shops at Port Huron were a great
attraction to the boy, who appears to have spent a good deal of his time
there. He who was to have much to do with the evolution of the modern
electric locomotive was fascinated by the mechanism of the steam
locomotive; and whenever he could get the chance Edison rode in the cab
with the engineer of his train. He became thoroughly familiar with the
intricacies of fire-box, boiler, valves, levers, and gears, and liked nothing
better than to handle the locomotive himself during the run. On one trip,
when the engineer lay asleep while his eager substitute piloted the train, the
boiler "primed," and a deluge overwhelmed the young driver, who stuck to
his post till the run and the ordeal were ended. Possibly this helped to spoil
a locomotive engineer, but went to make a great master of the new motive
power. "Steam is half an Englishman," said Emerson. The temptation is
strong to say that workaday electricity is half an American. Edison's own
account of the incident is very laughable: "The engine was one of a number
leased to the Grand Trunk by the Chicago, Burlington & Quincy. It had
bright brass bands all over, the woodwork beautifully painted, and
everything highly polished, which was the custom up to the time old
Commodore Vanderbilt stopped it on his roads. After running about fifteen
miles the fireman couldn't keep his eyes open (this event followed an all-
night dance of the trainmen's fraternal organization), and he agreed to
permit me to run the engine. I took charge, reducing the speed to about
twelve miles an hour, and brought the train of seven cars to her destination
at the Grand Trunk junction safely. But something occurred which was very
much out of the ordinary. I was very much worried about the water, and I
knew that if it got low the boiler was likely to explode. I hadn't gone twenty
miles before black damp mud blew out of the stack and covered every part
of the engine, including myself. I was about to awaken the fireman to find
out the cause of this when it stopped. Then I approached a station where the

Page 39
fireman always went out to the cowcatcher, opened the oil-cup on the
steam-chest, and poured oil in. I started to carry out the procedure when,
upon opening the oil-cup, the steam rushed out with a tremendous noise,
nearly knocking me off the engine. I succeeded in closing the oil-cup and
got back in the cab, and made up my mind that she would pull through
without oil. I learned afterward that the engineer always shut off steam
when the fireman went out to oil. This point I failed to notice. My powers
of observation were very much improved after this occurrence. Just before I
reached the junction another outpour of black mud occurred, and the whole
engine was a sight—so much so that when I pulled into the yard everybody
turned to see it, laughing immoderately. I found the reason of the mud was
that I carried so much water it passed over into the stack, and this washed
out all the accumulated soot."
One afternoon about a week before Christmas Edison's train jumped the
track near Utica, a station on the line. Four old Michigan Central cars with
rotten sills collapsed in the ditch and went all to pieces, distributing figs,
raisins, dates, and candies all over the track and the vicinity. Hating to see
so much waste, Edison tried to save all he could by eating it on the spot, but
as a result "our family doctor had the time of his life with me in this
connection."
An absurd incident described by Edison throws a vivid light on the free-
and-easy condition of early railroad travel and on the Southern
extravagance of the time. "In 1860, just before the war broke out there came
to the train one afternoon, in Detroit, two fine-looking young men
accompanied by a colored servant. They bought tickets for Port Huron, the
terminal point for the train. After leaving the junction just outside of
Detroit, I brought in the evening papers. When I came opposite the two
young men, one of them said: 'Boy, what have you got?' I said: 'Papers.' 'All
right.' He took them and threw them out of the window, and, turning to the
colored man, said: 'Nicodemus, pay this boy.' I told Nicodemus the amount,
and he opened a satchel and paid me. The passengers didn't know what to
make of the transaction. I returned with the illustrated papers and
magazines. These were seized and thrown out of the window, and I was told
to get my money of Nicodemus. I then returned with all the old magazines
and novels I had not been able to sell, thinking perhaps this would be too
much for them. I was small and thin, and the layer reached above my head,
and was all I could possibly carry. I had prepared a list, and knew the
steam-chest, and poured oil in. I started to carry out the procedure when,
upon opening the oil-cup, the steam rushed out with a tremendous noise,
nearly knocking me off the engine. I succeeded in closing the oil-cup and
got back in the cab, and made up my mind that she would pull through
without oil. I learned afterward that the engineer always shut off steam
when the fireman went out to oil. This point I failed to notice. My powers
of observation were very much improved after this occurrence. Just before I
reached the junction another outpour of black mud occurred, and the whole
engine was a sight—so much so that when I pulled into the yard everybody
turned to see it, laughing immoderately. I found the reason of the mud was
that I carried so much water it passed over into the stack, and this washed
out all the accumulated soot."
One afternoon about a week before Christmas Edison's train jumped the
track near Utica, a station on the line. Four old Michigan Central cars with
rotten sills collapsed in the ditch and went all to pieces, distributing figs,
raisins, dates, and candies all over the track and the vicinity. Hating to see
so much waste, Edison tried to save all he could by eating it on the spot, but
as a result "our family doctor had the time of his life with me in this
connection."
An absurd incident described by Edison throws a vivid light on the free-
and-easy condition of early railroad travel and on the Southern
extravagance of the time. "In 1860, just before the war broke out there came
to the train one afternoon, in Detroit, two fine-looking young men
accompanied by a colored servant. They bought tickets for Port Huron, the
terminal point for the train. After leaving the junction just outside of
Detroit, I brought in the evening papers. When I came opposite the two
young men, one of them said: 'Boy, what have you got?' I said: 'Papers.' 'All
right.' He took them and threw them out of the window, and, turning to the
colored man, said: 'Nicodemus, pay this boy.' I told Nicodemus the amount,
and he opened a satchel and paid me. The passengers didn't know what to
make of the transaction. I returned with the illustrated papers and
magazines. These were seized and thrown out of the window, and I was told
to get my money of Nicodemus. I then returned with all the old magazines
and novels I had not been able to sell, thinking perhaps this would be too
much for them. I was small and thin, and the layer reached above my head,
and was all I could possibly carry. I had prepared a list, and knew the
Page 40
amount in case they bit again. When I opened the door, all the passengers
roared with laughter. I walked right up to the young men. One asked me
what I had. I said 'Magazines and novels.' He promptly threw them out of
the window, and Nicodemus settled. Then I came in with cracked hickory
nuts, then pop-corn balls, and, finally, molasses candy. All went out of the
window. I felt like Alexander the Great!—I had no more chance! I had sold
all I had. Finally I put a rope to my trunk, which was about the size of a
carpenter's chest, and started to pull this from the baggage-car to the
passenger-car. It was almost too much for my strength, but at last I got it in
front of those men. I pulled off my coat, shoes, and hat, and laid them on
the chest. Then he asked: 'What have you got, boy?' I said: 'Everything, sir,
that I can spare that is for sale.' The passengers fairly jumped with laughter.
Nicodemus paid me $27 for this last sale, and threw the whole out of the
door in the rear of the car. These men were from the South, and I have
always retained a soft spot in my heart for a Southern gentleman."
While Edison was a newsboy on the train a request came to him one day
to go to the office of E. B. Ward & Company, at that time the largest owners
of steamboats on the Great Lakes. The captain of their largest boat had died
suddenly, and they wanted a message taken to another captain who lived
about fourteen miles from Ridgeway station on the railroad. This captain
had retired, taken up some lumber land, and had cleared part of it. Edison
was offered $15 by Mr. Ward to go and fetch him, but as it was a wild
country and would be dark, Edison stood out for $25, so that he could get
the companionship of another lad. The terms were agreed to. Edison arrived
at Ridgeway at 8.30 P.M., when it was raining and as dark as ink. Getting
another boy with difficulty to volunteer, he launched out on his errand in
the pitch-black night. The two boys carried lanterns, but the road was a
rough path through dense forest. The country was wild, and it was a usual
occurrence to see deer, bear, and coon skins nailed up on the sides of houses
to dry. Edison had read about bears, but couldn't remember whether they
were day or night prowlers. The farther they went the more apprehensive
they became, and every stump in the ravished forest looked like a bear. The
other lad proposed seeking safety up a tree, but Edison demurred on the
plea that bears could climb, and that the message must be delivered that
night to enable the captain to catch the morning train. First one lantern went
out, then the other. "We leaned up against a tree and cried. I thought if I
ever got out of that scrape alive I would know more about the habits of

what I had. I said 'Magazines and novels.' He promptly threw them out of

Page 41
animals and everything else, and be prepared for all kinds of mischance
when I undertook an enterprise. However, the intense darkness dilated the
pupils of our eyes so as to make them very sensitive, and we could just see
at times the outlines of the road. Finally, just as a faint gleam of daylight
arrived, we entered the captain's yard and delivered the message. In my
whole life I never spent such a night of horror as this, but I got a good
lesson."
An amusing incident of this period is told by Edison. "When I was a
boy," he says, "the Prince of Wales, the late King Edward, came to Canada
(1860). Great preparations were made at Sarnia, the Canadian town
opposite Port Huron. About every boy, including myself, went over to see
the affair. The town was draped in flags most profusely, and carpets were
laid on the cross-walks for the prince to walk on. There were arches, etc. A
stand was built raised above the general level, where the prince was to be
received by the mayor. Seeing all these preparations, my idea of a prince
was very high; but when he did arrive I mistook the Duke of Newcastle for
him, the duke being a fine-looking man. I soon saw that I was mistaken:
that the prince was a young stripling, and did not meet expectations. Several
of us expressed our belief that a prince wasn't much, after all, and said that
we were thoroughly disappointed. For this one boy was whipped. Soon the
Canuck boys attacked the Yankee boys, and we were all badly licked. I,
myself, got a black eye. That has always prejudiced me against that kind of
ceremonial and folly." It is certainly interesting to note that in later years the
prince for whom Edison endured the ignominy of a black eye made
generous compensation in a graceful letter accompanying the gold Albert
Medal awarded by the Royal Society of Arts.
Another incident of the period is as follows: "After selling papers in Port
Huron, which was often not reached until about 9.30 at night, I seldom got
home before 11.00 or 11.30. About half-way home from the station and the
town, and within twenty-five feet of the road in a dense wood, was a
soldiers' graveyard where three hundred soldiers were buried, due to a
cholera epidemic which took place at Fort Gratiot, near by, many years
previously. At first we used to shut our eyes and run the horse past this
graveyard, and if the horse stepped on a twig my heart would give a violent
movement, and it is a wonder that I haven't some valvular disease of that
organ. But soon this running of the horse became monotonous, and after a
while all fears of graveyards absolutely disappeared from my system. I was
when I undertook an enterprise. However, the intense darkness dilated the
pupils of our eyes so as to make them very sensitive, and we could just see

Page 42
in the condition of Sam Houston, the pioneer and founder of Texas, who, it
was said, knew no fear. Houston lived some distance from the town and
generally went home late at night, having to pass through a dark cypress
swamp over a corduroy road. One night, to test his alleged fearlessness, a
man stationed himself behind a tree and enveloped himself in a sheet. He
confronted Houston suddenly, and Sam stopped and said: 'If you are a man,
you can't hurt me. If you are a ghost, you don't want to hurt me. And if you
are the devil, come home with me; I married your sister!'"
It is not to be inferred, however, from some of the preceding statements
that the boy was of an exclusively studious bent of mind. He had then, as
now, the keen enjoyment of a joke, and no particular aversion to the
practical form. An incident of the time is in point. "After the breaking out of
the war there was a regiment of volunteer soldiers quartered at Fort Gratiot,
the reservation extending to the boundary line of our house. Nearly every
night we would hear a call, such as 'Corporal of the Guard, No. 1.' This
would be repeated from sentry to sentry until it reached the barracks, when
Corporal of the Guard, No. 1, would come and see what was wanted. I and
the little Dutch boy, after returning from the town after selling our papers,
thought we would take a hand at military affairs. So one night, when it was
very dark, I shouted for Corporal of the Guard, No. 1. The second sentry,
thinking it was the terminal sentry who shouted, repeated it to the third, and
so on. This brought the corporal along the half mile, only to find that he was
fooled. We tried him three nights; but the third night they were watching,
and caught the little Dutch boy, took him to the lock-up at the fort, and shut
him up. They chased me to the house. I rushed for the cellar. In one small
apartment there were two barrels of potatoes and a third one nearly empty. I
poured these remnants into the other barrels, sat down, and pulled the barrel
over my head, bottom up. The soldiers had awakened my father, and they
were searching for me with candles and lanterns. The corporal was
absolutely certain I came into the cellar, and couldn't see how I could have
gotten out, and wanted to know from my father if there was no secret
hiding-place. On assurance of my father, who said that there was not, he
said it was most extraordinary. I was glad when they left, as I was cramped,
and the potatoes were rotten that had been in the barrel and violently
offensive. The next morning I was found in bed, and received a good
switching on the legs from my father, the first and only one I ever received
from him, although my mother kept a switch behind the old Seth Thomas

CHAPTER IV
THE YOUNG TELEGRAPH OPERATOR
"WHILE a newsboy on the railroad," says Edison, "I got very much
interested in electricity, probably from visiting telegraph offices with a
chum who had tastes similar to mine." It will also have been noted that he
used the telegraph to get items for his little journal, and to bulletin his
special news of the Civil War along the line. The next step was natural, and
having with his knowledge of chemistry no trouble about "setting up" his
batteries, the difficulties of securing apparatus were chiefly those connected
with the circuits and the instruments. American youths to-day are given, if
of a mechanical turn of mind, to amateur telegraphy or telephony, but
seldom, if ever, have to make any part of the system constructed. In
Edison's boyish days it was quite different, and telegraphic supplies were
hard to obtain. But he and his "chum" had a line between their homes, built
of common stove-pipe wire. The insulators were bottles set on nails driven
into trees and short poles. The magnet wire was wound with rags for
insulation, and pieces of spring brass were used for keys. With an idea of
securing current cheaply, Edison applied the little that he knew about static
electricity, and actually experimented with cats, which he treated vigorously
as frictional machines until the animals fled in dismay, and Edison had
learned his first great lesson in the relative value of sources of electrical
energy. The line was made to work, however, and additional to the
messages that the boys interchanged, Edison secured practice in an
ingenious manner. His father insisted on 11.30 as proper bedtime, which left
but a short interval after the long day on the train. But each evening, when
the boy went home with a bundle of papers that had not been sold in the
town, his father would sit up reading the "returnables." Edison, therefore,
on some excuse, left the papers with his friend, but suggested that he could
get the news from him by telegraph, bit by bit. The scheme interested his
father, and was put into effect, the messages being written down and handed
over for perusal. This yielded good practice nightly, lasting until 12 and 1
o'clock, and was maintained for some time until Mr. Edison became willing

over for perusal. This yielded good practice nightly, lasting until 12 and 1
o'clock, and was maintained for some time until Mr. Edison became willing
Page 45
that his son should stay up for a reasonable time. The papers were then
brought home again, and the boys amused themselves to their hearts'
content until the line was pulled down by a stray cow wandering through
the orchard. Meantime better instruments had been secured, and the
rudiments of telegraphy had been fairly mastered.
The mixed train on which Edison was employed as newsboy did the way-
freight work and shunting at the Mount Clemens station, about half an hour
being usually spent in the work. One August morning, in 1862, while the
shunting was in progress, and a laden box-car had been pushed out of a
siding, Edison, who was loitering about the platform, saw the little son of
the station agent, Mr. J. U. Mackenzie, playing with the gravel on the main
track along which the car without a brakeman was rapidly approaching.
Edison dropped his papers and his glazed cap, and made a dash for the
child, whom he picked up and lifted to safety without a second to spare, as
the wheel of the car struck his heel; and both were cut about the face and
hands by the gravel ballast on which they fell. The two boys were picked up
by the train-hands and carried to the platform, and the grateful father at
once offered to teach the rescuer, whom he knew and liked, the art of train
telegraphy and to make an operator of him. It is needless to say that the
proposal was eagerly accepted.
Edison found time for his new studies by letting one of his friends look
after the newsboy work on the train for part of the trip, reserving to himself
the run between Port Huron and Mount Clemens. That he was already well
qualified as a beginner is evident from the fact that he had mastered the
Morse code of the telegraphic alphabet, and was able to take to the station a
neat little set of instruments he had just finished with his own hands at a
gun-shop in Detroit. This was probably a unique achievement in itself
among railway operators of that day or of later times. The drill of the
student involved chiefly the acquisition of the special signals employed in
railway work, including the numerals and abbreviations applied to save
time. Some of these have passed into the slang of the day, "73" being well
known as a telegrapher's expression of compliments or good wishes, while
"23" is an accident or death message, and has been given broader popular
significance as a general synonym for "hoodoo." All of this came easily to
Edison, who had, moreover, as his Herald showed, an unusual familiarity
with train movement along that portion of the Grand Trunk road.

Page 46
Three or four months were spent pleasantly and profitably by the youth
in this course of study, and Edison took to it enthusiastically, giving it no
less than eighteen hours a day. He then put up a little telegraph line from the
station to the village, a distance of about a mile, and opened an office in a
drug store; but the business was naturally very small. The telegraph
operator at Port Huron knowing of his proficiency, and wanting to get into
the United States Military Telegraph Corps, where the pay in those days of
the Civil War was high, succeeded in convincing his brother-in-law, Mr. M.
Walker, that young Edison could fill the position. Edison was, of course,
well acquainted with the operators along the road and at the southern
terminal, and took up his new duties very easily. The office was located in a
jewelry store, where newspapers and periodicals were also sold. Edison was
to be found at the office both day and night, sleeping there. "I became quite
valuable to Mr. Walker. After working all day I worked at the office nights
as well, for the reason that 'press report' came over one of the wires until 3
A.M., and I would cut in and copy it as well as I could, to become more
rapidly proficient. The goal of the rural telegraph operator was to be able to
take press. Mr. Walker tried to get my father to apprentice me at $20 per
month, but they could not agree. I then applied for a job on the Grand Trunk
Railroad as a railway operator, and was given a place, nights, at Stratford
Junction, Canada." Apparently his friend Mackenzie helped him in the
matter. The position carried a salary of $25 per month. No serious
objections were raised by his family, for the distance from Port Huron was
not great, and Stratford was near Bayfield, the old home from which the
Edisons had come, so that there were doubtless friends or even relatives in
the vicinity. This was in 1863.
Mr. Walker was an observant man, who has since that time installed a
number of waterworks systems and obtained several patents of his own. He
describes the boy of sixteen as engrossed intensely in his experiments and
scientific reading, and somewhat indifferent, for this reason, to his duties as
operator. This office was not particularly busy, taking from $50 to $75 a
month, but even the messages taken in would remain unsent on the hook
while Edison was in the cellar below trying to solve some chemical
problem. The manager would see him studying sometimes an article in such
a paper as the Scientific American, and then disappearing to buy a few
sundries for experiments. Returning from the drug store with his chemicals,
he would not be seen again until required by his duties, or until he had
in this course of study, and Edison took to it enthusiastically, giving it no
less than eighteen hours a day. He then put up a little telegraph line from the

objections were raised by his family, for the distance from Port Huron was
not great, and Stratford was near Bayfield, the old home from which the
Edisons had come, so that there were doubtless friends or even relatives in
the vicinity. This was in 1863.
Mr. Walker was an observant man, who has since that time installed a
number of waterworks systems and obtained several patents of his own. He
describes the boy of sixteen as engrossed intensely in his experiments and
scientific reading, and somewhat indifferent, for this reason, to his duties as
operator. This office was not particularly busy, taking from $50 to $75 a
month, but even the messages taken in would remain unsent on the hook
while Edison was in the cellar below trying to solve some chemical
problem. The manager would see him studying sometimes an article in such
a paper as the Scientific American, and then disappearing to buy a few
sundries for experiments. Returning from the drug store with his chemicals,
he would not be seen again until required by his duties, or until he had
Page 47
found out for himself, if possible, in this offhand manner, whether what he
had read was correct or not. When he had completed his experiment all
interest in it was lost, and the jars and wires would be left to any fate that
might befall them. In like manner Edison would make free use of the
watchmaker's tools that lay on the little table in the front window, and
would take the wire pliers there without much thought as to their value as
distinguished from a lineman's tools. The one idea was to do quickly what
he wanted to do; and the same swift, almost headlong trial of anything that
comes to hand, while the fervor of a new experiment is felt, has been noted
at all stages of the inventor's career. One is reminded of Palissy's
recklessness, when in his efforts to make the enamel melt on his pottery he
used the very furniture of his home for firewood.
Mr. Edison remarks the fact that there was very little difference between
the telegraph of that time and of to-day, except the general use of the old
Morse register with the dots and dashes recorded by indenting paper strips
that could be read and checked later at leisure if necessary. He says: "The
telegraph men couldn't explain how it worked, and I was always trying to
get them to do so. I think they couldn't. I remember the best explanation I
got was from an old Scotch line repairer employed by the Montreal
Telegraph Company, which operated the railroad wires. He said that if you
had a dog like a dachshund, long enough to reach from Edinburgh to
London, if you pulled his tail in Edinburgh he would bark in London. I
could understand that, but I never could get it through me what went
through the dog or over the wire." To-day Mr. Edison is just as unable to
solve the inner mystery of electrical transmission. Nor is he alone. At the
banquet given to celebrate his jubilee in 1896 as professor at Glasgow
University, Lord Kelvin, the greatest physicist of our time, admitted with
tears in his eyes and the note of tragedy in his voice, that when it came to
explaining the nature of electricity, he knew just as little as when he had
begun as a student, and felt almost as though his life had been wasted while
he tried to grapple with the great mystery of physics.
Another episode of this period is curious in its revelation of the tenacity
with which Edison has always held to some of his oldest possessions with a
sense of personal attachment. "While working at Stratford Junction," he
says, "I was told by one of the freight conductors that in the freight-house at
Goodrich there were several boxes of old broken-up batteries. I went there
and found over eighty cells of the well-known Grove nitric-acid battery.

Page 48
The operator there, who was also agent, when asked by me if I could have
the electrodes of each cell, made of sheet platinum, gave his permission
readily, thinking they were of tin. I removed them all, amounting to several
ounces. Platinum even in those days was very expensive, costing several
dollars an ounce, and I owned only three small strips. I was overjoyed at
this acquisition, and those very strips and the reworked scrap are used to
this day in my laboratory over forty years later."
It was at Stratford that Edison's inventiveness was first displayed. The
hours of work of a night operator are usually from 7 P.M. to 7 A.M., and to
insure attention while on duty it is often provided that the operator every
hour, from 9 P.M. until relieved by the day operator, shall send in the signal
"6" to the train dispatcher's office. Edison revelled in the opportunity for
study and experiment given him by his long hours of freedom in the
daytime, but needed sleep, just as any healthy youth does. Confronted by
the necessity of sending in this watchman's signal as evidence that he was
awake and on duty, he constructed a small wheel with notches on the rim,
and attached it to the clock in such a manner that the night-watchman could
start it when the line was quiet, and at each hour the wheel revolved and
sent in accurately the dots required for "sixing." The invention was a
success, the device being, indeed, similar to that of the modern district
messenger box; but it was soon noticed that, in spite of the regularity of the
report, "Sf" could not be raised even if a train message were sent
immediately after. Detection and a reprimand came in due course, but were
not taken very seriously.
A serious occurrence that might have resulted in accident drove him soon
after from Canada, although the youth could hardly be held to blame for it.
Edison says: "This night job just suited me, as I could have the whole day to
myself. I had the faculty of sleeping in a chair any time for a few minutes at
a time. I taught the night-yardman my call, so I could get half an hour's
sleep now and then between trains, and in case the station was called the
watchman would awaken me. One night I got an order to hold a freight
train, and I replied that I would. I rushed out to find the signalman, but
before I could find him and get the signal set, the train ran past. I ran to the
telegraph office, and reported that I could not hold her. The reply was:
'Hell!' The train dispatcher, on the strength of my message that I would hold
the train, had permitted another to leave the last station in the opposite
direction. There was a lower station near the junction where the day
the electrodes of each cell, made of sheet platinum, gave his permission
readily, thinking they were of tin. I removed them all, amounting to several
ounces. Platinum even in those days was very expensive, costing several
dollars an ounce, and I owned only three small strips. I was overjoyed at

operator slept. I started for it on foot. The night was dark, and I fell into a
culvert and was knocked senseless." Owing to the vigilance of the two
engineers on the locomotives, who saw each other approaching on the
straight single track, nothing more dreadful happened than a summons to
the thoughtless operator to appear before the general manager at Toronto.
On reaching the manager's office, his trial for neglect of duty was
fortunately interrupted by the call of two Englishmen; and while their
conversation proceeded, Edison slipped quietly out of the room, hurried to
the Grand Trunk freight depot, found a conductor he knew taking out a
freight train for Sarnia, and was not happy until the ferry-boat from Sarnia
had landed him once more on the Michigan shore. The Grand Trunk still
owes Mr. Edison the wages due him at the time he thus withdrew from its
service, but the claim has never been pressed.
The same winter of 1863-64, while at Port Huron, Edison had a further
opportunity of displaying his ingenuity. An ice-jam had broken the light
telegraph cable laid in the bed of the river across to Sarnia, and thus
communication was interrupted. The river is three-quarters of a mile wide,
and could not be crossed on foot; nor could the cable be repaired. Edison at
once suggested using the steam whistle of the locomotive, and by
manipulating the valve conversed the short and long outbursts of shrill
sound into the Morse code. An operator on the Sarnia shore was quick
enough to catch the significance of the strange whistling, and messages
were thus sent in wireless fashion across the ice-floes in the river. It is said
that such signals were also interchanged by military telegraphers during the
war, and possibly Edison may have heard of the practice; but be that as it
may, he certainly showed ingenuity and resource in applying such a method
to meet the necessity. It is interesting to note that at this point the Grand
Trunk now has its St. Clair tunnel, through which the trains are hauled
under the river-bed by electric locomotives.
Edison had now begun unconsciously the roaming and drifting that took
him during the next five years all over the Middle States, and that might
well have wrecked the career of any one less persistent and industrious. It
was a period of his life corresponding to the Wanderjahre of the German
artisan, and was an easy way of gratifying a taste for travel without the risk
of privation. To-day there is little temptation to the telegrapher to go to
distant parts of the country on the chance that he may secure a livelihood at
the key. The ranks are well filled everywhere, and of late years the

Page 50
telegraph as an art or industry has shown relatively slight expansion, owing
chiefly to the development of telephony. Hence, if vacancies occur, there
are plenty of operators available, and salaries have remained so low as to
lead to one or two formidable and costly strikes that unfortunately took no
account of the economic conditions of demand and supply. But in the days
of the Civil War there was a great dearth of skilful manipulators of the key.
About fifteen hundred of the best operators in the country were at the front
on the Federal side alone, and several hundred more had enlisted. This
created a serious scarcity, and a nomadic operator going to any telegraphic
centre would be sure to find a place open waiting for him. At the close of
the war a majority of those who had been with the two opposed armies
remained at the key under more peaceful surroundings, but the rapid
development of the commercial and railroad systems fostered a new
demand, and then for a time it seemed almost impossible to train new
operators fast enough. In a few years, however, the telephone sprang into
vigorous existence, dating from 1876, drawing off some of the most
adventurous spirits from the telegraph field; and the deterrent influence of
the telephone on the telegraph had made itself felt by 1890. The expiration
of the leading Bell telephone patents, five years later, accentuated even
more sharply the check that had been put on telegraphy, as hundreds and
thousands of "independent" telephone companies were then organized,
throwing a vast network of toll lines over Ohio, Indiana, Illinois, Iowa, and
other States, and affording cheap, instantaneous means of communication
without any necessity for the intervention of an operator.
It will be seen that the times have changed radically since Edison became
a telegrapher, and that in this respect a chapter of electrical history has been
definitely closed. There was a day when the art offered a distinct career to
all of its practitioners, and young men of ambition and good family were
eager to begin even as messenger boys, and were ready to undergo a severe
ordeal of apprenticeship with the belief that they could ultimately attain
positions of responsibility and profit. At the same time operators have
always been shrewd enough to regard the telegraph as a stepping-stone to
other careers in life. A bright fellow entering the telegraph service to-day
finds the experience he may gain therein valuable, but he soon realizes that
there are not enough good-paying official positions to "go around," so as to
give each worthy man a chance after he has mastered the essentials of the
art. He feels, therefore, that to remain at the key involves either stagnation

or deterioration, and that after, say, twenty-five years of practice he will
have lost ground as compared with friends who started out in other
occupations. The craft of an operator, learned without much difficulty, is
very attractive to a youth, but a position at the key is no place for a man of
mature years. His services, with rare exceptions, grow less valuable as he
advances in age and nervous strain breaks him down. On the contrary, men
engaged in other professions find, as a rule, that they improve and advance
with experience, and that age brings larger rewards and opportunities.
The list of well-known Americans who have been graduates of the key is
indeed an extraordinary one, and there is no department of our national life
in which they have not distinguished themselves. The contrast, in this
respect, between them and their European colleagues is highly significant.
In Europe the telegraph systems are all under government management, the
operators have strictly limited spheres of promotion, and at the best the
transition from one kind of employment to another is not made so easily as
in the New World. But in the United States we have seen Rufus Bullock
become Governor of Georgia, and Ezra Cornell Governor of New York.
Marshall Jewell was Postmaster-General of President Grant's Cabinet, and
Daniel Lamont was Secretary of State in President Cleveland's. Gen. T. T.
Eckert, past-President of the Western Union Telegraph Company, was
Assistant Secretary of War under President Lincoln; and Robert J. Wynne,
afterward a consul-general, served as Assistant Postmaster General. A very
large proportion of the presidents and leading officials of the great railroad
systems are old telegraphers, including Messrs. W. C. Brown, President of
the New York Central Railroad, and Marvin Hughitt, President of the
Chicago & North western Railroad. In industrial and financial life there
have been Theodore N. Vail, President of the Bell telephone system; L. C.
Weir, late President of the Adams Express; A. B. Chandler, President of the
Postal Telegraph and Cable Company; Sir W. Van Home, identified with
Canadian development; Robert C. Clowry, President of the Western Union
Telegraph Company; D. H. Bates, Manager of the Baltimore & Ohio
telegraph for Robert Garrett; and Andrew Carnegie, the greatest ironmaster
the world has ever known, as well as its greatest philanthropist. In
journalism there have been leaders like Edward Rosewater, founder of the
Omaha Bee; W. J. Elverson, of the Philadelphia Press; and Frank A.
Munsey, publisher of half a dozen big magazines. George Kennan has

been successful as dramatists. These are but typical of hundreds of men
who could be named who have risen from work at the key to become
recognized leaders in differing spheres of activity.
But roving has never been favorable to the formation of steady habits.
The young men who thus floated about the country from one telegraph
office to another were often brilliant operators, noted for speed in sending
and receiving, but they were undisciplined, were without the restraining
influences of home life, and were so highly paid for their work that they
could indulge freely in dissipation if inclined that way. Subjected to nervous
tension for hours together at the key, many of them unfortunately took to
drink, and having ended one engagement in a city by a debauch that closed
the doors of the office to them, would drift away to the nearest town, and
there securing work, would repeat the performance. At one time, indeed,
these men were so numerous and so much in evidence as to constitute a
type that the public was disposed to accept as representative of the
telegraphic fraternity; but as the conditions creating him ceased to exist, the
"tramp operator" also passed into history. It was, however, among such
characters that Edison was very largely thrown in these early days of
aimless drifting, to learn something perhaps of their nonchalant philosophy
of life, sharing bed and board with them under all kinds of adverse
conditions, but always maintaining a stoic abstemiousness, and never
feeling other than a keen regret at the waste of so much genuine ability and
kindliness on the part of those knights errant of the key whose inevitable
fate might so easily have been his own.
Such a class or group of men can always be presented by an individual
type, and this is assuredly best embodied in Milton F. Adams, one of
Edison's earliest and closest friends, to whom reference will be made in
later chapters, and whose life has been so full of adventurous episodes that
he might well be regarded as the modern Gil Blas. That career is certainly
well worth the telling as "another story," to use the Kipling phrase. Of him
Edison says: "Adams was one of a class of operators never satisfied to work
at any place for any great length of time. He had the 'wanderlust.' After
enjoying hospitality in Boston in 1868-69, on the floor of my hall-bedroom,
which was a paradise for the entomologist, while the boarding-house itself
was run on the banting system of flesh reduction, he came to me one day
and said: 'Good-bye, Edison; I have got sixty cents, and I am going to San
Francisco.' And he did go. How, I never knew personally. I learned
who could be named who have risen from work at the key to become

Page 53
afterward that he got a job there, and then within a week they had a
telegraphers' strike. He got a big torch and sold patent medicine on the
streets at night to support the strikers. Then he went to Peru as partner of a
man who had a grizzly bear which they proposed entering against a bull in
the bull-ring in that city. The grizzly was killed in five minutes, and so the
scheme died. Then Adams crossed the Andes, and started a market-report
bureau in Buenos Ayres. This didn't pay, so he started a restaurant in
Pernambuco, Brazil. There he did very well, but something went wrong (as
it always does to a nomad), so he went to the Transvaal, and ran a panorama
called 'Paradise Lost' in the Kaffir kraals. This didn't pay, and he became the
editor of a newspaper; then went to England to raise money for a railroad in
Cape Colony. Next I heard of him in New York, having just arrived from
Bogota, United States of Colombia, with a power of attorney and $2000
from a native of that republic, who had applied for a patent for tightening a
belt to prevent it from slipping on a pulley—a device which he thought a
new and great invention, but which was in use ever since machinery was
invented. I gave Adams, then, a position as salesman for electrical
apparatus. This he soon got tired of, and I lost sight of him." Adams, in
speaking of this episode, says that when he asked for transportation
expenses to St. Louis, Edison pulled out of his pocket a ferry ticket to
Hoboken, and said to his associates: "I'll give him that, and he'll get there
all right." This was in the early days of electric lighting; but down to the
present moment the peregrinations of this versatile genius of the key have
never ceased in one hemisphere or the other, so that as Mr. Adams himself
remarked to the authors in April, 1908: "The life has been somewhat
variegated, but never dull."
The fact remains also that throughout this period Edison, while himself a
very Ishmael, never ceased to study, explore, experiment. Referring to this
beginning of his career, he mentions a curious fact that throws light on his
ceaseless application. "After I became a telegraph operator," he says, "I
practiced for a long time to become a rapid reader of print, and got so
expert I could sense the meaning of a whole line at once. This faculty, I
believe, should be taught in schools, as it appears to be easily acquired.
Then one can read two or three books in a day, whereas if each word at a
time only is sensed, reading is laborious."
telegraphers' strike. He got a big torch and sold patent medicine on the
streets at night to support the strikers. Then he went to Peru as partner of a
man who had a grizzly bear which they proposed entering against a bull in
the bull-ring in that city. The grizzly was killed in five minutes, and so the
scheme died. Then Adams crossed the Andes, and started a market-report
bureau in Buenos Ayres. This didn't pay, so he started a restaurant in
Pernambuco, Brazil. There he did very well, but something went wrong (as
it always does to a nomad), so he went to the Transvaal, and ran a panorama
called 'Paradise Lost' in the Kaffir kraals. This didn't pay, and he became the
editor of a newspaper; then went to England to raise money for a railroad in
Cape Colony. Next I heard of him in New York, having just arrived from
Bogota, United States of Colombia, with a power of attorney and $2000
from a native of that republic, who had applied for a patent for tightening a
belt to prevent it from slipping on a pulley—a device which he thought a
new and great invention, but which was in use ever since machinery was
invented. I gave Adams, then, a position as salesman for electrical
apparatus. This he soon got tired of, and I lost sight of him." Adams, in
speaking of this episode, says that when he asked for transportation
expenses to St. Louis, Edison pulled out of his pocket a ferry ticket to
Hoboken, and said to his associates: "I'll give him that, and he'll get there
all right." This was in the early days of electric lighting; but down to the
present moment the peregrinations of this versatile genius of the key have
never ceased in one hemisphere or the other, so that as Mr. Adams himself
remarked to the authors in April, 1908: "The life has been somewhat
variegated, but never dull."

CHAPTER V
ARDUOUS YEARS IN THE CENTRAL WEST
IN 1903, when accepting the position of honorary electrician to the
International Exposition held in St. Louis in 1904, to commemorate the
centenary of the Louisiana Purchase, Mr. Edison spoke in his letter of the
Central West as a "region where as a young telegraph operator I spent many
arduous years before moving East." The term of probation thus referred to
did not end until 1868, and while it lasted Edison's wanderings carried him
from Detroit to New Orleans, and took him, among other cities, to
Indianapolis, Cincinnati, Louisville, and Memphis, some of which he
visited twice in his peregrinations to secure work. From Canada, after the
episodes noted in the last chapter, he went to Adrian, Michigan, and of what
happened there Edison tells a story typical of his wanderings for several
years to come. "After leaving my first job at Stratford Junction, I got a
position as operator on the Lake Shore & Michigan Southern at Adrian,
Michigan, in the division superintendent's office. As usual, I took the 'night
trick,' which most operators disliked, but which I preferred, as it gave me
more leisure to experiment. I had obtained from the station agent a small
room, and had established a little shop of my own. One day the day
operator wanted to get off, and I was on duty. About 9 o'clock the
superintendent handed me a despatch which he said was very important,
and which I must get off at once. The wire at the time was very busy, and I
asked if I should break in. I got orders to do so, and acting under those
orders of the superintendent, I broke in and tried to send the despatch; but
the other operator would not permit it, and the struggle continued for ten
minutes. Finally I got possession of the wire and sent the message. The
superintendent of telegraph, who then lived in Adrian and went to his office
in Toledo every day, happened that day to be in the Western Union office
up-town—and it was the superintendent I was really struggling with! In
about twenty minutes he arrived livid with rage, and I was discharged on
the spot. I informed him that the general superintendent had told me to
break in and send the despatch, but the general superintendent then and

break in and send the despatch, but the general superintendent then and
Page 56
there repudiated the whole thing. Their families were socially close, so I
was sacrificed. My faith in human nature got a slight jar."
Edison then went to Toledo and secured a position at Fort Wayne, on the
Pittsburg, Fort Wayne & Chicago Railroad, now leased to the Pennsylvania
system. This was a "day job," and he did not like it. He drifted two months
later to Indianapolis, arriving there in the fall of 1864, when he was at first
assigned to duty at the Union Station at a salary of $75 a month for the
Western Union Telegraph Company, whose service he now entered, and
with which he has been destined to maintain highly important and close
relationships throughout a large part of his life. Superintendent Wallick
appears to have treated him generously and to have loaned him instruments,
a kindness that was greatly appreciated, for twenty years later the inventor
called on his old employer, and together they visited the scene where the
borrowed apparatus had been mounted on a rough board in the depot.
Edison did not stay long in Indianapolis, however, resigning in February,
1865, and proceeding to Cincinnati. The transfer was possibly due to
trouble caused by one of his early inventions embodying what has been
characterized by an expert as "probably the most simple and ingenious
arrangement of connections for a repeater." His ambition was to take "press
report," but finding, even after considerable practice, that he "broke"
frequently, he adjusted two embossing Morse registers—one to receive the
press matter, and the other to repeat the dots and dashes at a lower speed, so
that the message could be copied leisurely. Hence he could not be rushed or
"broken" in receiving, while he could turn out "copy" that was a marvel of
neatness and clearness. All was well so long as ordinary conditions
prevailed, but when an unusual pressure occurred the little system fell
behind, and the newspapers complained of the slowness with which reports
were delivered to them. It is easy to understand that with matter received at
a rate of forty words per minute and worked off at twenty-five words per
minute a serious congestion or delay would result, and the newspapers were
more anxious for the news than they were for fine penmanship.
Of this device Mr. Edison remarks: "Together we took press for several
nights, my companion keeping the apparatus in adjustment and I copying.
The regular press operator would go to the theatre or take a nap, only
finishing the report after 1 A.M. One of the newspapers complained of bad
copy toward the end of the report—that, is from 1 to 3 A.M., and requested
that the operator taking the report up to 1 A.M.—which was ourselves—
was sacrificed. My faith in human nature got a slight jar."

take it all, as the copy then was perfectly unobjectionable. This led to an
investigation by the manager, and the scheme was forbidden.
"This instrument, many years afterward, was applied by me for
transferring messages from one wire to any other wire simultaneously, or
after any interval of time. It consisted of a disk of paper, the indentations
being formed in a volute spiral, exactly as in the disk phonograph to-day. It
was this instrument which gave me the idea of the phonograph while
working on the telephone."
Arrived in Cincinnati, where he got employment in the Western Union
commercial telegraph department at a wage of $60 per month, Edison made
the acquaintance of Milton F. Adams, already referred to as facile princeps
the typical telegrapher in all his more sociable and brilliant aspects.
Speaking of that time, Mr. Adams says: "I can well recall when Edison
drifted in to take a job. He was a youth of about eighteen years, decidedly
unprepossessing in dress and rather uncouth in manner. I was twenty-one,
and very dudish. He was quite thin in those days, and his nose was very
prominent, giving a Napoleonic look to his face, although the curious
resemblance did not strike me at the time. The boys did not take to him
cheerfully, and he was lonesome. I sympathized with him, and we became
close companions. As an operator he had no superiors and very few equals.
Most of the time he was monkeying with the batteries and circuits, and
devising things to make the work of telegraphy less irksome. He also
relieved the monotony of office-work by fitting up the battery circuits to
play jokes on his fellow-operators, and to deal with the vermin that infested
the premises. He arranged in the cellar what he called his 'rat paralyzer,' a
very simple contrivance consisting of two plates insulated from each other
and connected with the main battery. They were so placed that when a rat
passed over them the fore feet on the one plate and the hind feet on the
other completed the circuit and the rat departed this life, electrocuted."
Shortly after Edison's arrival at Cincinnati came the close of the Civil
War and the assassination of President Lincoln. It was natural that
telegraphers should take an intense interest in the general struggle, for not
only did they handle all the news relating to it, but many of them were at
one time or another personal participants. For example, one of the operators
in the Cincinnati office was George Ellsworth, who was telegrapher for
Morgan, the famous Southern Guerrilla, and was with him when he made
investigation by the manager, and the scheme was forbidden.

in the Cincinnati office was George Ellsworth, who was telegrapher for
Morgan, the famous Southern Guerrilla, and was with him when he made
Page 58
his raid into Ohio and was captured near the Pennsylvania line. Ellsworth
himself made a narrow escape by swimming the Ohio River with the aid of
an army mule. Yet we can well appreciate the unimpressionable way in
which some of the men did their work, from an anecdote that Mr. Edison
tells of that awful night of Friday, April 14, 1865: "I noticed," he says, "an
immense crowd gathering in the street outside a newspaper office. I called
the attention of the other operators to the crowd, and we sent a messenger
boy to find the cause of the excitement. He returned in a few minutes and
shouted 'Lincoln's shot.' Instinctively the operators looked from one face to
another to see which man had received the news. All the faces were blank,
and every man said he had not taken a word about the shooting. 'Look over
your files,' said the boss to the man handling the press stuff. For a few
moments we waited in suspense, and then the man held up a sheet of paper
containing a short account of the shooting of the President. The operator
had worked so mechanically that he had handled the news without the
slightest knowledge of its significance." Mr. Adams says that at the time the
city was en fete on account of the close of the war, the name of the assassin
was received by telegraph, and it was noted with a thrill of horror that it
was that of a brother of Edwin Booth and of Junius Brutus Booth—the
latter of whom was then playing at the old National Theatre. Booth was
hurried away into seclusion, and the next morning the city that had been so
gay over night with bunting was draped with mourning.
Edison's diversions in Cincinnati were chiefly those already observed. He
read a great deal, but spent most of his leisure in experiment. Mr. Adams
remarks: "Edison and I were very fond of tragedy. Forrest and John
McCullough were playing at the National Theatre, and when our capital
was sufficient we would go to see those eminent tragedians alternate in
Othello and Iago. Edison always enjoyed Othello greatly. Aside from an
occasional visit to the Loewen Garden 'over the Rhine,' with a glass of beer
and a few pretzels, consumed while listening to the excellent music of a
German band, the theatre was the sum and substance of our innocent
dissipation."
The Cincinnati office, as a central point, appears to have been attractive
to many of the clever young operators who graduated from it to positions of
larger responsibility. Some of them were conspicuous for their skill and
versatility. Mr. Adams tells this interesting story as an illustration: "L. C.
Weir, or Charlie, as he was known, at that time agent for the Adams Express
himself made a narrow escape by swimming the Ohio River with the aid of
an army mule. Yet we can well appreciate the unimpressionable way in

Weir, or Charlie, as he was known, at that time agent for the Adams Express
Page 59
Company, had the remarkable ability of taking messages and copying them
twenty-five words behind the sender. One day he came into the operating-
room, and passing a table he heard Louisville calling Cincinnati. He
reached over to the key and answered the call. My attention was arrested by
the fact that he walked off after responding, and the sender happened to be a
good one. Weir coolly asked for a pen, and when he sat down the sender
was just one message ahead of him with date, address, and signature.
Charlie started in, and in a beautiful, large, round hand copied that message.
The sender went right along, and when he finished with six messages closed
his key. When Weir had done with the last one the sender began to think
that after all there had been no receiver, as Weir did not 'break,' but simply
gave his O. K. He afterward became president of the Adams Express, and
was certainly a wonderful operator." The operating-room referred to was on
the fifth floor of the building with no elevators.
Those were the early days of trade unionism in telegraphy, and the
movement will probably never quite die out in the craft which has always
shown so much solidarity. While Edison was in Cincinnati a delegation of
five union operators went over from Cleveland to form a local branch, and
the occasion was one of great conviviality. Night came, but the unionists
were conspicuous by their absence, although more circuits than one were
intolerant of delay and clamorous for attention—-eight local unionists being
away. The Cleveland report wire was in special need, and Edison, almost
alone in the office, devoted himself to it all through the night and until 3
o'clock the next morning, when he was relieved.
He had previously been getting $80 a month, and had eked this out by
copying plays for the theatre. His rating was that of a "plug" or inferior
operator; but he was determined to lift himself into the class of first-class
operators, and had kept up the practice of going to the office at night to
"copy press," acting willingly as a substitute for any operator who wanted
to get off for a few hours—which often meant all night. Speaking of this
special ordeal, for which he had thus been unconsciously preparing, Edison
says: "My copy looked fine if viewed as a whole, as I could write a
perfectly straight line across the wide sheet, which was not ruled. There
were no flourishes, but the individual letters would not bear close
inspection. When I missed understanding a word, there was no time to think
what it was, so I made an illegible one to fill in, trusting to the printers to
sense it. I knew they could read anything, although Mr. Bloss, an editor of
twenty-five words behind the sender. One day he came into the operating-
room, and passing a table he heard Louisville calling Cincinnati. He
reached over to the key and answered the call. My attention was arrested by
the fact that he walked off after responding, and the sender happened to be a

Page 60
the Inquirer, made such bad copy that one of his editorials was pasted up on
the notice-board in the telegraph office with an offer of one dollar to any
man who could 'read twenty consecutive words.' Nobody ever did it. When
I got through I was too nervous to go home, so waited the rest of the night
for the day manager, Mr. Stevens, to see what was to be the outcome of this
Union formation and of my efforts. He was an austere man, and I was afraid
of him. I got the morning papers, which came out at 4 A. M., and the press
report read perfectly, which surprised me greatly. I went to work on my
regular day wire to Portsmouth, Ohio, and there was considerable
excitement, but nothing was said to me, neither did Mr. Stevens examine
the copy on the office hook, which I was watching with great interest.
However, about 3 P. M. he went to the hook, grabbed the bunch and looked
at it as a whole without examining it in detail, for which I was thankful.
Then he jabbed it back on the hook, and I knew I was all right. He walked
over to me, and said: 'Young man, I want you to work the Louisville wire
nights; your salary will be $125.' Thus I got from the plug classification to
that of a 'first-class man.'"
But no sooner was this promotion secured than he started again on his
wanderings southward, while his friend Adams went North, neither having
any difficulty in making the trip. "The boys in those days had extraordinary
facilities for travel. As a usual thing it was only necessary for them to board
a train and tell the conductor they were operators. Then they would go as
far as they liked. The number of operators was small, and they were in
demand everywhere." It was in this way Edison made his way south as far
as Memphis, Tennessee, where the telegraph service at that time was under
military law, although the operators received $125 a month. Here again
Edison began to invent and improve on existing apparatus, with the result of
having once more to "move on." The story may be told in his own terse
language: "I was not the inventor of the auto repeater, but while in Memphis
I worked on one. Learning that the chief operator, who was a protege of the
superintendent, was trying in some way to put New York and New Orleans
together for the first time since the close of the war, I redoubled my efforts,
and at 2 o'clock one morning I had them speaking to each other. The office
of the Memphis Avalanche was in the same building. The paper got wind of
it and sent messages. A column came out in the morning about it; but when
I went to the office in the afternoon to report for duty I was discharged with
out explanation. The superintendent would not even give me a pass to
the notice-board in the telegraph office with an offer of one dollar to any

starved at Decatur, Alabama, and had to stay three days before going on
north to Nashville. Arrived in that city, I went to the telegraph office, got
money enough to buy a little solid food, and secured a pass to Louisville. I
had a companion with me who was also out of a job. I arrived at Louisville
on a bitterly cold day, with ice in the gutters. I was wearing a linen duster
and was not much to look at, but got a position at once, working on a press
wire. My travelling companion was less successful on account of his
'record.' They had a limit even in those days when the telegraph service was
so demoralized."
Some reminiscences of Mr. Edison are of interest as bearing not only
upon the "demoralized" telegraph service, but the conditions from which
the New South had to emerge while working out its salvation. "The
telegraph was still under military control, not having been turned over to the
original owners, the Southern Telegraph Company. In addition to the
regular force, there was an extra force of two or three operators, and some
stranded ones, who were a burden to us, for board was high. One of these
derelicts was a great source of worry to me, personally. He would come in
at all hours and either throw ink around or make a lot of noise. One night he
built a fire in the grate and started to throw pistol cartridges into the flames.
These would explode, and I was twice hit by the bullets, which left a black-
and-blue mark. Another night he came in and got from some part of the
building a lot of stationery with 'Confederate States' printed at the head. He
was a fine operator, and wrote a beautiful hand. He would take a sheet of
this paper, write capital 'A', and then take another sheet and make the 'A'
differently; and so on through the alphabet; each time crumpling the paper
up in his hand and throwing it on the floor. He would keep this up until the
room was filled nearly flush with the table. Then he would quit.
"Everything at that time was 'wide open.' Disorganization reigned
supreme. There was no head to anything. At night myself and a companion
would go over to a gorgeously furnished faro-bank and get our midnight
lunch. Everything was free. There were over twenty keno-rooms running.
One of them that I visited was in a Baptist church, the man with the wheel
being in the pulpit, and the gamblers in the pews.
"While there the manager of the telegraph office was arrested for
something I never understood, and incarcerated in a military prison about
starved at Decatur, Alabama, and had to stay three days before going on
north to Nashville. Arrived in that city, I went to the telegraph office, got
money enough to buy a little solid food, and secured a pass to Louisville. I
had a companion with me who was also out of a job. I arrived at Louisville

Page 62
half a mile from the office. The building was in plain sight from the office,
and four stories high. He was kept strictly incommunicado. One day,
thinking he might be confined in a room facing the office, I put my arm out
of the window and kept signalling dots and dashes by the movement of the
arm. I tried this several times for two days. Finally he noticed it, and putting
his arm through the bars of the window he established communication with
me. He thus sent several messages to his friends, and was afterward set
free."
Another curious story told by Edison concerns a fellow-operator on night
duty at Chattanooga Junction, at the time he was at Memphis: "When it was
reported that Hood was marching on Nashville, one night a Jew came into
the office about 11 o'clock in great excitement, having heard the Hood
rumor. He, being a large sutler, wanted to send a message to save his goods.
The operator said it was impossible—that orders had been given to send no
private messages. Then the Jew wanted to bribe my friend, who steadfastly
refused for the reason, as he told the Jew, that he might be court-martialled
and shot. Finally the Jew got up to $800. The operator swore him to secrecy
and sent the message. Now there was no such order about private messages,
and the Jew, finding it out, complained to Captain Van Duzer, chief of
telegraphs, who investigated the matter, and while he would not discharge
the operator, laid him off indefinitely. Van Duzer was so lenient that if an
operator were discharged, all the operator had to do was to wait three days
and then go and sit on the stoop of Van Duzer's office all day, and he would
be taken back. But Van Duzer swore he would never give in in this case. He
said that if the operator had taken $800 and sent the message at the regular
rate, which was twenty-five cents, it would have been all right, as the Jew
would be punished for trying to bribe a military operator; but when the
operator took the $800 and then sent the message deadhead, he couldn't
stand it, and he would never relent."
A third typical story of this period deals with a cipher message for
Thomas. Mr. Edison narrates it as follows: "When I was an operator in
Cincinnati working the Louisville wire nights for a time, one night a man
over on the Pittsburg wire yelled out: 'D. I. cipher,' which meant that there
was a cipher message from the War Department at Washington and that it
was coming—and he yelled out 'Louisville.' I started immediately to call up
that place. It was just at the change of shift in the office. I could not get
Louisville, and the cipher message began to come. It was taken by the
and four stories high. He was kept strictly incommunicado. One day,
thinking he might be confined in a room facing the office, I put my arm out
of the window and kept signalling dots and dashes by the movement of the
arm. I tried this several times for two days. Finally he noticed it, and putting

was a cipher message from the War Department at Washington and that it
was coming—and he yelled out 'Louisville.' I started immediately to call up
that place. It was just at the change of shift in the office. I could not get
Louisville, and the cipher message began to come. It was taken by the
Page 63
operator on the other table direct from the War Department. It was for
General Thomas, at Nashville. I called for about twenty minutes and
notified them that I could not get Louisville. I kept at it for about fifteen
minutes longer, and notified them that there was still no answer from
Louisville. They then notified the War Department that they could not get
Louisville. Then we tried to get it by all kinds of roundabout ways, but in
no case could anybody get them at that office. Soon a message came from
the War Department to send immediately for the manager of the Cincinnati
office. He was brought to the office and several messages were exchanged,
the contents of which, of course, I did not know, but the matter appeared to
be very serious, as they were afraid of General Hood, of the Confederate
Army, who was then attempting to march on Nashville; and it was very
important that this cipher of about twelve hundred words or so should be
got through immediately to General Thomas. I kept on calling up to 12 or 1
o'clock, but no Louisville. About 1 o'clock the operator at the Indianapolis
office got hold of an operator on a wire which ran from Indianapolis to
Louisville along the railroad, who happened to come into his office. He
arranged with this operator to get a relay of horses, and the message was
sent through Indianapolis to this operator who had engaged horses to carry
the despatches to Louisville and find out the trouble, and get the despatches
through without delay to General Thomas. In those days the telegraph
fraternity was rather demoralized, and the discipline was very lax. It was
found out a couple of days afterward that there were three night operators at
Louisville. One of them had gone over to Jeffersonville and had fallen off a
horse and broken his leg, and was in a hospital. By a remarkable
coincidence another of the men had been stabbed in a keno-room, and was
also in hospital while the third operator had gone to Cynthiana to see a man
hanged and had got left by the train."
I think the most important line of
investigation is the production of
Electricity direct from carbon.
Edison
Young Edison remained in Louisville for about two years, quite a long
stay for one with such nomadic instincts. It was there that he perfected the
peculiar vertical style of writing which, beginning with him in telegraphy,
later became so much of a fad with teachers of penmanship and in the
schools. He says of this form of writing, a current example of which is
General Thomas, at Nashville. I called for about twenty minutes and
notified them that I could not get Louisville. I kept at it for about fifteen
minutes longer, and notified them that there was still no answer from

later became so much of a fad with teachers of penmanship and in the
schools. He says of this form of writing, a current example of which is
Page 64
given above: "I developed this style in Louisville while taking press reports.
My wire was connected to the 'blind' side of a repeater at Cincinnati, so that
if I missed a word or sentence, or if the wire worked badly, I could not
break in and get the last words, because the Cincinnati man had no
instrument by which he could hear me. I had to take what came. When I got
the job, the cable across the Ohio River at Covington, connecting with the
line to Louisville, had a variable leak in it, which caused the strength of the
signalling current to make violent fluctuations. I obviated this by using
several relays, each with a different adjustment, working several sounders
all connected with one sounding-plate. The clatter was bad, but I could read
it with fair ease. When, in addition to this infernal leak, the wires north to
Cleveland worked badly, it required a large amount of imagination to get
the sense of what was being sent. An imagination requires an appreciable
time for its exercise, and as the stuff was coming at the rate of thirty-five to
forty words a minute, it was very difficult to write down what was coming
and imagine what wasn't coming. Hence it was necessary to become a very
rapid writer, so I started to find the fastest style. I found that the vertical
style, with each letter separate and without any flourishes, was the most
rapid, and that the smaller the letter the greater the rapidity. As I took on an
average from eight to fifteen columns of news report every day, it did not
take long to perfect this method." Mr. Edison has adhered to this
characteristic style of penmanship down to the present time.
As a matter of fact, the conditions at Louisville at that time were not
much better than they had been at Memphis. The telegraph operating-room
was in a deplorable condition. It was on the second story of a dilapidated
building on the principal street of the city, with the battery-room in the rear;
behind which was the office of the agent of the Associated Press. The
plastering was about one-third gone from the ceiling. A small stove, used
occasionally in the winter, was connected to the chimney by a tortuous pipe.
The office was never cleaned. The switchboard for manipulating the wires
was about thirty-four inches square. The brass connections on it were black
with age and with the arcing effects of lightning, which, to young Edison,
seemed particularly partial to Louisville. "It would strike on the wires," he
says, "with an explosion like a cannon-shot, making that office no place for
an operator with heart-disease." Around the dingy walls were a dozen
tables, the ends next to the wall. They were about the size of those seen in
old-fashioned country hotels for holding the wash-bowl and pitcher. The

tables, the ends next to the wall. They were about the size of those seen in
old-fashioned country hotels for holding the wash-bowl and pitcher. The
Page 65
copper wires connecting the instruments to the switchboard were small,
crystallized, and rotten. The battery-room was filled with old record-books
and message bundles, and one hundred cells of nitric-acid battery, arranged
on a stand in the centre of the room. This stand, as well as the floor, was
almost eaten through by the destructive action of the powerful acid. Grim
and uncompromising as the description reads, it was typical of the
equipment in those remote days of the telegraph at the close of the war.
Illustrative of the length to which telegraphers could go at a time when
they were so much in demand, Edison tells the following story: "When I
took the position there was a great shortage of operators. One night at 2
A.M. another operator and I were on duty. I was taking press report, and the
other man was working the New York wire. We heard a heavy tramp, tramp,
tramp on the rickety stairs. Suddenly the door was thrown open with great
violence, dislodging it from one of the hinges. There appeared in the
doorway one of the best operators we had, who worked daytime, and who
was of a very quiet disposition except when intoxicated. He was a great
friend of the manager of the office. His eyes were bloodshot and wild, and
one sleeve had been torn away from his coat. Without noticing either of us
he went up to the stove and kicked it over. The stove-pipe fell, dislocated at
every joint. It was half full of exceedingly fine soot, which floated out and
filled the room completely. This produced a momentary respite to his
labors. When the atmosphere had cleared sufficiently to see, he went around
and pulled every table away from the wall, piling them on top of the stove
in the middle of the room. Then he proceeded to pull the switchboard away
from the wall. It was held tightly by screws. He succeeded, finally, and
when it gave way he fell with the board, and striking on a table cut himself
so that he soon became covered with blood. He then went to the battery-
room and knocked all the batteries off on the floor. The nitric acid soon
began to combine with the plaster in the room below, which was the public
receiving-room for messengers and bookkeepers. The excess acid poured
through and ate up the account-books. After having finished everything to
his satisfaction, he left. I told the other operator to do nothing. We would
leave things just as they were, and wait until the manager came. In the mean
time, as I knew all the wires coming through to the switchboard, I rigged up
a temporary set of instruments so that the New York business could be
cleared up, and we also got the remainder of the press matter. At 7 o'clock
the day men began to appear. They were told to go down-stairs and wait the
crystallized, and rotten. The battery-room was filled with old record-books
and message bundles, and one hundred cells of nitric-acid battery, arranged

Page 66
coming of the manager. At 8 o'clock he appeared, walked around, went into
the battery-room, and then came to me, saying: 'Edison, who did this?' I told
him that Billy L. had come in full of soda-water and invented the ruin
before him. He walked backward and forward, about a minute, then coming
up to my table put his fist down, and said: 'If Billy L. ever does that again, I
will discharge him.' It was needless to say that there were other operators
who took advantage of that kind of discipline, and I had many calls at night
after that, but none with such destructive effects."
This was one aspect of life as it presented itself to the sensitive and
observant young operator in Louisville. But there was another, more
intellectual side, in the contact afforded with journalism and its leaders, and
the information taken in almost unconsciously as to the political and social
movements of the time. Mr. Edison looks back on this with great
satisfaction. "I remember," he says, "the discussions between the celebrated
poet and journalist George D. Prentice, then editor of the Courier-Journal,
and Mr. Tyler, of the Associated Press. I believe Prentice was the father of
the humorous paragraph of the American newspaper. He was poetic, highly
educated, and a brilliant talker. He was very thin and small. I do not think
he weighed over one hundred and twenty five pounds. Tyler was a graduate
of Harvard, and had a very clear enunciation, and, in sharp contrast to
Prentice, he was a large man. After the paper had gone to press, Prentice
would generally come over to Tyler's office and start talking. Having while
in Tyler's office heard them arguing on the immortality of the soul, etc., I
asked permission of Mr. Tyler if, after finishing the press matter, I might
come in and listen to the conversation, which I did many times after. One
thing I never could comprehend was that Tyler had a sideboard with liquors
and generally crackers. Prentice would pour out half a glass of what they
call corn whiskey, and would dip the crackers in it and eat them. Tyler took
it sans food. One teaspoonful of that stuff would put me to sleep."
Mr. Edison throws also a curious side-light on the origin of the comic
column in the modern American newspaper, the telegraph giving to a new
joke or a good story the ubiquity and instantaneity of an important historical
event. "It was the practice of the press operators all over the country at that
time, when a lull occurred, to start in and send jokes or stories the day men
had collected; and these were copied and pasted up on the bulletin-board.
Cleveland was the originating office for 'press,' which it received from New
York, and sent it out simultaneously to Milwaukee, Chicago, Toledo,
the battery-room, and then came to me, saying: 'Edison, who did this?' I told
him that Billy L. had come in full of soda-water and invented the ruin
before him. He walked backward and forward, about a minute, then coming

Page 67
Detroit, Pittsburg, Columbus, Dayton, Cincinnati, Indianapolis, Vincennes,
Terre Haute, St. Louis, and Louisville. Cleveland would call first on
Milwaukee, if he had anything. If so, he would send it, and Cleveland
would repeat it to all of us. Thus any joke or story originating anywhere in
that area was known the next day all over. The press men would come in
and copy anything which could be published, which was about three per
cent. I collected, too, quite a large scrap-book of it, but unfortunately have
lost it."
Edison tells an amusing story of his own pursuits at this time. Always an
omnivorous reader, he had some difficulty in getting a sufficient quantity of
literature for home consumption, and was in the habit of buying books at
auctions and second-hand stores. One day at an auction-room he secured a
stack of twenty unbound volumes of the North American Review for two
dollars. These he had bound and delivered at the telegraph office. One
morning, when he was free as usual at 3 o'clock, he started off at a rapid
pace with ten volumes on his shoulder. He found himself very soon the
subject of a fusillade. When he stopped, a breathless policeman grabbed
him by the throat and ordered him to drop his parcel and explain matters, as
a suspicious character. He opened the package showing the books,
somewhat to the disgust of the officer, who imagined he had caught a
burglar sneaking away in the dark alley with his booty. Edison explained
that being deaf he had heard no challenge, and therefore had kept moving;
and the policeman remarked apologetically that it was fortunate for Edison
he was not a better shot.
The incident is curiously revelatory of the character of the man, for it
must be admitted that while literary telegraphers are by no means scarce,
there are very few who would spend scant savings on back numbers of a
ponderous review at an age when tragedy, beer, and pretzels are far more
enticing. Through all his travels Edison has preserved those books, and has
them now in his library at Llewellyn Park, on Orange Mountain, New
Jersey.
Drifting after a time from Louisville, Edison made his way as far north as
Detroit, but, like the famous Duke of York, soon made his way back again.
Possibly the severer discipline after the happy-go-lucky regime in the
Southern city had something to do with this restlessness, which again
manifested itself, however, on his return thither. The end of the war had left
Terre Haute, St. Louis, and Louisville. Cleveland would call first on
Milwaukee, if he had anything. If so, he would send it, and Cleveland
would repeat it to all of us. Thus any joke or story originating anywhere in
that area was known the next day all over. The press men would come in
and copy anything which could be published, which was about three per
cent. I collected, too, quite a large scrap-book of it, but unfortunately have
lost it."
Edison tells an amusing story of his own pursuits at this time. Always an
omnivorous reader, he had some difficulty in getting a sufficient quantity of
literature for home consumption, and was in the habit of buying books at
auctions and second-hand stores. One day at an auction-room he secured a
stack of twenty unbound volumes of the North American Review for two
dollars. These he had bound and delivered at the telegraph office. One
morning, when he was free as usual at 3 o'clock, he started off at a rapid
pace with ten volumes on his shoulder. He found himself very soon the
subject of a fusillade. When he stopped, a breathless policeman grabbed
him by the throat and ordered him to drop his parcel and explain matters, as
a suspicious character. He opened the package showing the books,
somewhat to the disgust of the officer, who imagined he had caught a
burglar sneaking away in the dark alley with his booty. Edison explained
that being deaf he had heard no challenge, and therefore had kept moving;
and the policeman remarked apologetically that it was fortunate for Edison
he was not a better shot.
The incident is curiously revelatory of the character of the man, for it
must be admitted that while literary telegraphers are by no means scarce,
there are very few who would spend scant savings on back numbers of a
ponderous review at an age when tragedy, beer, and pretzels are far more
enticing. Through all his travels Edison has preserved those books, and has
them now in his library at Llewellyn Park, on Orange Mountain, New
Jersey.
Drifting after a time from Louisville, Edison made his way as far north as
Detroit, but, like the famous Duke of York, soon made his way back again.
Possibly the severer discipline after the happy-go-lucky regime in the
Southern city had something to do with this restlessness, which again
manifested itself, however, on his return thither. The end of the war had left
Page 68
the South a scene of destruction and desolation, and many men who had
fought bravely and well found it hard to reconcile themselves to the grim
task of reconstruction. To them it seemed better to "let ill alone" and seek
some other clime where conditions would be less onerous. At this moment a
great deal of exaggerated talk was current as to the sunny life and easy
wealth of Latin America, and under its influences many "unreconstructed"
Southerners made their way to Mexico, Brazil, Peru, or the Argentine.
Telegraph operators were naturally in touch with this movement, and
Edison's fertile imagination was readily inflamed by the glowing idea of all
these vague possibilities. Again he threw up his steady work and, with a
couple of sanguine young friends, made his way to New Orleans. They had
the notion of taking positions in the Brazilian Government telegraphs, as an
advertisement had been inserted in some paper stating that operators were
wanted. They had timed their departure from Louisville so as to catch a
specially chartered steamer, which was to leave New Orleans for Brazil on a
certain day, to convey a large number of Confederates and their families,
who were disgusted with the United States and were going to settle in
Brazil, where slavery still prevailed. Edison and his friends arrived in New
Orleans just at the time of the great riot, when several hundred negroes
were killed, and the city was in the hands of a mob. The Government had
seized the steamer chartered for Brazil, in order to bring troops from the
Yazoo River to New Orleans to stop the rioting. The young operators
therefore visited another shipping-office to make inquiries as to vessels for
Brazil, and encountered an old Spaniard who sat in a chair near the steamer
agent's desk, and to whom they explained their intentions. He had lived and
worked in South America, and was very emphatic in his assertion, as he
shook his yellow, bony finger at them, that the worst mistake they could
possibly make would be to leave the United States. He would not leave on
any account, and they as young Americans would always regret it if they
forsook their native land, whose freedom, climate, and opportunities could
not be equalled anywhere on the face of the globe. Such sincere advice as
this could not be disdained, and Edison made his way North again. One
cannot resist speculation as to what might have happened to Edison himself
and to the development of electricity had he made this proposed plunge into
the enervating tropics. It will be remembered that at a somewhat similar
crisis in life young Robert Burns entertained seriously the idea of forsaking
Scotland for the West Indies. That he did not go was certainly better for

Page 69
Scottish verse, to which he contributed later so many immortal lines; and it
was probably better for himself, even if he died a gauger. It is simply
impossible to imagine Edison working out the phonograph, telephone, and
incandescent lamp under the tropical climes he sought. Some years later he
was informed that both his companions had gone to Vera Cruz, Mexico, and
had died there of yellow fever.
Work was soon resumed at Louisville, where the dilapidated old office
occupied at the close of the war had been exchanged for one much more
comfortable and luxurious in its equipment. As before, Edison was allotted
to press report, and remembers very distinctly taking the Presidential
message and veto of the District of Columbia bill by President Johnson. As
the matter was received over the wire he paragraphed it so that each printer
had exactly three lines, thus enabling the matter to be set up very
expeditiously in the newspaper offices. This earned him the gratitude of the
editors, a dinner, and all the newspaper "exchanges" he wanted. Edison's
accounts of the sprees and debauches of other night operators in the loosely
managed offices enable one to understand how even a little steady
application to the work in hand would be appreciated. On one occasion
Edison acted as treasurer for his bibulous companions, holding the stakes,
so to speak, in order that the supply of liquor might last longer. One of the
mildest mannered of the party took umbrage at the parsimony of the
treasurer and knocked him down, whereupon the others in the party set
upon the assailant and mauled him so badly that he had to spend three
weeks in hospital. At another time two of his companions sharing the
temporary hospitality of his room smashed most of the furniture, and went
to bed with their boots on. Then his kindly good-nature rebelled. "I felt that
this was running hospitality into the ground, so I pulled them out and left
them on the floor to cool off from their alcoholic trance."
Edison seems on the whole to have been fairly comfortable and happy in
Louisville, surrounding himself with books and experimental apparatus, and
even inditing a treatise on electricity. But his very thirst for knowledge and
new facts again proved his undoing. The instruments in the handsome new
offices were fastened in their proper places, and operators were strictly
forbidden to remove them, or to use the batteries except on regular work.
This prohibition meant little to Edison, who had access to no other
instruments except those of the company. "I went one night," he says, "into
the battery-room to obtain some sulphuric acid for experimenting. The

carboy tipped over, the acid ran out, went through to the manager's room
below, and ate up his desk and all the carpet. The next morning I was
summoned before him, and told that what the company wanted was
operators, not experimenters. I was at liberty to take my pay and get out."
The fact that Edison is a very studious man, an insatiate lover and reader
of books, is well known to his associates; but surprise is often expressed at
his fund of miscellaneous information. This, it will be seen, is partly
explained by his work for years as a "press" reporter. He says of this: "The
second time I was in Louisville, they had moved into a new office, and the
discipline was now good. I took the press job. In fact, I was a very poor
sender, and therefore made the taking of press report a specialty. The
newspaper men allowed me to come over after going to press at 3 A.M. and
get all the exchanges I wanted. These I would take home and lay at the foot
of my bed. I never slept more than four or five hours' so that I would awake
at nine or ten and read these papers until dinner-time. I thus kept posted,
and knew from their activity every member of Congress, and what
committees they were on; and all about the topical doings, as well as the
prices of breadstuffs in all the primary markets. I was in a much better
position than most operators to call on my imagination to supply missing
words or sentences, which were frequent in those days of old, rotten wires,
badly insulated, especially on stormy nights. Upon such occasions I had to
supply in some cases one-fifth of the whole matter—pure guessing—but I
got caught only once. There had been some kind of convention in Virginia,
in which John Minor Botts was the leading figure. There was great
excitement about it, and two votes had been taken in the convention on the
two days. There was no doubt that the vote the next day would go a certain
way. A very bad storm came up about 10 o'clock, and my wire worked very
badly. Then there was a cessation of all signals; then I made out the words
'Minor Botts.' The next was a New York item. I filled in a paragraph about
the convention and how the vote had gone, as I was sure it would. But next
day I learned that instead of there being a vote the convention had
adjourned without action until the day after." In like manner, it was at
Louisville that Mr. Edison got an insight into the manner in which great
political speeches are more frequently reported than the public suspects.
"The Associated Press had a shorthand man travelling with President
Johnson when he made his celebrated swing around the circle in a private
train delivering hot speeches in defence of his conduct. The man engaged
below, and ate up his desk and all the carpet. The next morning I was
summoned before him, and told that what the company wanted was
operators, not experimenters. I was at liberty to take my pay and get out."

train delivering hot speeches in defence of his conduct. The man engaged
Page 71
me to write out the notes from his reading. He came in loaded and on the
verge of incoherence. We started in, but about every two minutes I would
have to scratch out whole paragraphs and insert the same things said in
another and better way. He would frequently change words, always to the
betterment of the speech. I couldn't understand this, and when he got
through, and I had copied about three columns, I asked him why those
changes, if he read from notes. 'Sonny,' he said, 'if these politicians had their
speeches published as they deliver them, a great many shorthand writers
would be out of a job. The best shorthanders and the holders of good
positions are those who can take a lot of rambling, incoherent stuff and
make a rattling good speech out of it.'"
Going back to Cincinnati and beginning his second term there as an
operator, Edison found the office in new quarters and with greatly improved
management. He was again put on night duty, much to his satisfaction. He
rented a room in the top floor of an office building, bought a cot and an oil-
stove, a foot lathe, and some tools. He cultivated the acquaintance of Mr.
Sommers, superintendent of telegraph of the Cincinnati & Indianapolis
Railroad, who gave him permission to take such scrap apparatus as he
might desire, that was of no use to the company. With Sommers on one
occasion he had an opportunity to indulge his always strong sense of humor.
"Sommers was a very witty man," he says, "and fond of experimenting. We
worked on a self-adjusting telegraph relay, which would have been very
valuable if we could have got it. I soon became the possessor of a second-
hand Ruhmkorff induction coil, which, although it would only give a small
spark, would twist the arms and clutch the hands of a man so that he could
not let go of the apparatus. One day we went down to the round-house of
the Cincinnati & Indianapolis Railroad and connected up the long wash-
tank in the room with the coil, one electrode being connected to earth.
Above this wash-room was a flat roof. We bored a hole through the roof,
and could see the men as they came in. The first man as he entered dipped
his hands in the water. The floor being wet he formed a circuit, and up went
his hands. He tried it the second time, with the same result. He then stood
against the wall with a puzzled expression. We surmised that he was waiting
for somebody else to come in, which occurred shortly after—with the same
result. Then they went out, and the place was soon crowded, and there was
considerable excitement. Various theories were broached to explain the
curious phenomenon. We enjoyed the sport immensely." It must be

remembered that this was over forty years ago, when there was no popular
instruction in electricity, and when its possibilities for practical joking were
known to very few. To-day such a crowd of working-men would be sure to
include at least one student of a night school or correspondence course who
would explain the mystery offhand.
Note has been made of the presence of Ellsworth in the Cincinnati office,
and his service with the Confederate guerrilla Morgan, for whom he tapped
Federal wires, read military messages, sent false ones, and did serious
mischief generally. It is well known that one operator can recognize another
by the way in which he makes his signals—it is his style of handwriting.
Ellsworth possessed in a remarkable degree the skill of imitating these
peculiarities, and thus he deceived the Union operators easily. Edison says
that while apparently a quiet man in bearing, Ellsworth, after the excitement
of fighting, found the tameness of a telegraph office obnoxious, and that he
became a bad "gun man" in the Panhandle of Texas, where he was killed.
"We soon became acquainted," says Edison of this period in Cincinnati,
"and he wanted me to invent a secret method of sending despatches so that
an intermediate operator could not tap the wire and understand it. He said
that if it could be accomplished, he could sell it to the Government for a
large sum of money. This suited me, and I started in and succeeded in
making such an instrument, which had in it the germ of my quadruplex now
used throughout the world, permitting the despatch of four messages over
one wire simultaneously. By the time I had succeeded in getting the
apparatus to work, Ellsworth suddenly disappeared. Many years afterward I
used this little device again for the same purpose. At Menlo Park, New
Jersey, I had my laboratory. There were several Western Union wires cut
into the laboratory, and used by me in experimenting at night. One day I sat
near an instrument which I had left connected during the night. I soon found
it was a private wire between New York and Philadelphia, and I heard
among a lot of stuff a message that surprised me. A week after that I had
occasion to go to New York, and, visiting the office of the lessee of the
wire, I asked him if he hadn't sent such and such a message. The expression
that came over his face was a sight. He asked me how I knew of any
message. I told him the circumstances, and suggested that he had better
cipher such communications, or put on a secret sounder. The result of the
interview was that I installed for him my old Cincinnati apparatus, which
was used thereafter for many years."

Edison did not make a very long stay in Cincinnati this time, but went
home after a while to Port Huron. Soon tiring of idleness and isolation he
sent "a cry from Macedonia" to his old friend "Milt" Adams, who was in
Boston, and whom he wished to rejoin if he could get work promptly in the
East.
Edison himself gives the details of this eventful move, when he went East
to grow up with the new art of electricity. "I had left Louisville the second
time, and went home to see my parents. After stopping at home for some
time, I got restless, and thought I would like to work in the East. Knowing
that a former operator named Adams, who had worked with me in the
Cincinnati office, was in Boston, I wrote him that I wanted a job there. He
wrote back that if I came on immediately he could get me in the Western
Union office. I had helped out the Grand Trunk Railroad telegraph people
by a new device when they lost one of the two submarine cables they had
across the river, making the remaining cable act just as well for their
purpose, as if they had two. I thought I was entitled to a pass, which they
conceded; and I started for Boston. After leaving Toronto a terrific blizzard
came up and the train got snowed under in a cut. After staying there twenty-
four hours, the trainmen made snowshoes of fence-rail splints and started
out to find food, which they did about a half mile away. They found a
roadside inn, and by means of snowshoes all the passengers were taken to
the inn. The train reached Montreal four days late. A number of the
passengers and myself went to the military headquarters to testify in favor
of a soldier who was on furlough, and was two days late, which was a
serious matter with military people, I learned. We willingly did this, for this
soldier was a great story-teller, and made the time pass quickly. I met here a
telegraph operator named Stanton, who took me to his boarding-house, the
most cheerless I have ever been in. Nobody got enough to eat; the
bedclothes were too short and too thin; it was 28 degrees below zero, and
the wash-water was frozen solid. The board was cheap, being only $1.50
per week.
"Stanton said that the usual live-stock accompaniment of operators'
boarding-houses was absent; he thought the intense cold had caused them to
hibernate. Stanton, when I was working in Cincinnati, left his position and
went out on the Union Pacific to work at Julesburg, which was a cattle town
at that time and very tough. I remember seeing him off on the train, never
expecting to see him again. Six months afterward, while working press wire

in Cincinnati, about 2 A.M., there was flung into the middle of the
operating-room a large tin box. It made a report like a pistol, and we all
jumped up startled. In walked Stanton. 'Gentlemen,' he said 'I have just
returned from a pleasure trip to the land beyond the Mississippi. All my
wealth is contained in my metallic travelling case and you are welcome to
it.' The case contained one paper collar. He sat down, and I noticed that he
had a woollen comforter around his neck with his coat buttoned closely.
The night was intensely warm. He then opened his coat and revealed the
fact that he had nothing but the bare skin. 'Gentlemen,' said he, 'you see

from the limit of impecuniosity was Edison himself, as he landed in Boston
in 1868 after this wintry ordeal.

telegraph operators, and says: "Nothing could be more complete than the

CHAPTER VI
WORK AND INVENTION IN BOSTON
MILTON ADAMS was working in the office of the Franklin Telegraph
Company in Boston when he received Edison's appeal from Port Huron,
and with characteristic impetuosity at once made it his business to secure a
position for his friend. There was no opening in the Franklin office, so
Adams went over to the Western Union office, and asked the manager, Mr.
George F. Milliken, if he did not want an operator who, like young
Lochinvar, came out of the West. "What kind of copy does he make?" was
the cautious response. "I passed Edison's letter through the window for his
inspection. Milliken read it, and a look of surprise came over his
countenance as he asked me if he could take it off the line like that. I said he
certainly could, and that there was nobody who could stick him. Milliken
said that if he was that kind of an operator I could send for him, and I wrote
to Edison to come on, as I had a job for him in the main office of the
Western Union." Meantime Edison had secured his pass over the Grand
Trunk Railroad, and spent four days and nights on the journey, suffering
extremes of cold and hunger. Franklin's arrival in Philadelphia finds its
parallel in the very modest debut of Adams's friend in Boston.
It took only five minutes for Edison to get the "job," for Superintendent
Milliken, a fine type of telegraph official, saw quickly through the
superficialities, and realized that it was no ordinary young operator he was
engaging. Edison himself tells the story of what happened. "The manager
asked me when I was ready to go to work. 'Now,' I replied I was then told to
return at 5.30 P.M., and punctually at that hour I entered the main operating-
room and was introduced to the night manager. The weather being cold, and
being clothed poorly, my peculiar appearance caused much mirth, and, as I
afterward learned, the night operators had consulted together how they
might 'put up a job on the jay from the woolly West.' I was given a pen and
assigned to the New York No. 1 wire. After waiting an hour, I was told to
come over to a special table and take a special report for the Boston Herald,

It took only five minutes for Edison to get the "job," for Superintendent
Milliken, a fine type of telegraph official, saw quickly through the

the conspirators having arranged to have one of the fastest senders in New

York send the despatch and 'salt' the new man. I sat down unsuspiciously at
the table, and the New York man started slowly. Soon he increased his
speed, to which I easily adapted my pace. This put my rival on his mettle,
and he put on his best powers, which, however, were soon reached. At this
point I happened to look up, and saw the operators all looking over my
shoulder, with their faces shining with fun and excitement. I knew then that
they were trying to put up a job on me, but kept my own counsel. The New
York man then commenced to slur over his words, running them together
and sticking the signals; but I had been used to this style of telegraphy in
taking report, and was not in the least discomfited. Finally, when I thought
the fun had gone far enough, and having about completed the special, I
quietly opened the key and remarked, telegraphically, to my New York
friend: 'Say, young man, change off and send with your other foot.' This
broke the New York man all up, and he turned the job over to another man
to finish."
Edison had a distaste for taking press report, due to the fact that it was
steady, continuous work, and interfered with the studies and investigations
that could be carried on in the intervals of ordinary commercial telegraphy.
He was not lazy in any sense. While he had no very lively interest in the
mere routine work of a telegraph office, he had the profoundest curiosity as
to the underlying principles of electricity that made telegraphy possible, and
he had an unflagging desire and belief in his own ability to improve the
apparatus he handled daily. The whole intellectual atmosphere of Boston
was favorable to the development of the brooding genius in this shy,
awkward, studious youth, utterly indifferent to clothes and personal
appearance, but ready to spend his last dollar on books and scientific
paraphernalia. It is matter of record that he did once buy a new suit for
thirty dollars in Boston, but the following Sunday, while experimenting
with acids in his little workshop, the suit was spoiled. "That is what I get for
putting so much money in a new suit," was the laconic remark of the youth,
who was more than delighted to pick up a complete set of Faraday's works
about the same time. Adams says that when Edison brought home these
books at 4 A.M. he read steadily until breakfast-time, and then he remarked,
enthusiastically: "Adams, I have got so much to do and life is so short, I am
going to hustle." And thereupon he started on a run for breakfast. Edison
himself says: "It was in Boston I bought Faraday's works. I think I must
have tried about everything in those books. His explanations were simple.

He used no mathematics. He was the Master Experimenter. I don't think
there were many copies of Faraday's works sold in those days. The only
people who did anything in electricity were the telegraphers and the
opticians making simple school apparatus to demonstrate the principles."
One of these firms was Palmer & Hall, whose catalogue of 1850 showed a
miniature electric locomotive made by Mr. Thomas Hall, and exhibited in
operation the following year at the Charitable Mechanics' Fair in Boston. In
1852 Mr. Hall made for a Dr. A. L. Henderson, of Buffalo, New York, a
model line of railroad with electric-motor engine, telegraph line, and
electric railroad signals, together with a figure operating the signals at each
end of the line automatically. This was in reality the first example of
railroad trains moved by telegraph signals, a practice now so common and
universal as to attract no comment. To show how little some fundamental
methods can change in fifty years, it may be noted that Hall conveyed the
current to his tiny car through forty feet of rail, using the rail as conductor,
just as Edison did more than thirty years later in his historic experiments for
Villard at Menlo Park; and just as a large proportion of American trolley
systems do at this present moment.
It was among such practical, investigating folk as these that Edison was
very much at home. Another notable man of this stamp, with whom Edison
was thrown in contact, was the late Mr. Charles Williams, who, beginning
his career in the electrical field in the forties, was at the height of activity as
a maker of apparatus when Edison arrived in the city; and who afterward, as
an associate of Alexander Graham Bell, enjoyed the distinction of being the
first manufacturer in the world of telephones. At his Court Street workshop
Edison was a frequent visitor. Telegraph repairs and experiments were
going on constantly, especially on the early fire-alarm telegraphs [1] of
Farmer and Gamewell, and with the aid of one of the men there—probably
George Anders—Edison worked out into an operative model his first
invention, a vote-recorder, the first Edison patent, for which papers were
executed on October 11, 1868, and which was taken out June 1, 1869, No.
90,646. The purpose of this particular device was to permit a vote in the
National House of Representatives to be taken in a minute or so, complete
lists being furnished of all members voting on the two sides of any question

operator who was the financial backer to the extent of $100. The invention
when completed was taken to Washington. I think it was exhibited before a

committee that had something to do with the Capitol. The chairman of the
committee, after seeing how quickly and perfectly it worked, said: 'Young
man, if there is any invention on earth that we don't want down here, it is
this. One of the greatest weapons in the hands of a minority to prevent bad
legislation is filibustering on votes, and this instrument would prevent it.' I
saw the truth of this, because as press operator I had taken miles of
Congressional proceedings, and to this day an enormous amount of time is
wasted during each session of the House in foolishly calling the members'
names and recording and then adding their votes, when the whole operation
could be done in almost a moment by merely pressing a particular button at
each desk. For filibustering purposes, however, the present methods are
most admirable." Edison determined from that time forth to devote his
inventive faculties only to things for which there was a real, genuine
demand, something that subserved the actual necessities of humanity. This
first patent was taken out for him by the late Hon. Carroll D. Wright,
afterward U. S. Commissioner of Labor, and a well-known publicist, then
practicing patent law in Boston. He describes Edison as uncouth in manner,
a chewer rather than a smoker of tobacco, but full of intelligence and ideas.

system embodies a central office to which notice can be sent
from any number of signal boxes of the outbreak of a fire in
the district covered by the box, the central office in turn
calling out the nearest fire engines, and warning the fire
department in general of the occurrence. Such fire alarms
can be exchanged automatically, or by operators, and are
sometimes associated with a large fire-alarm bell or
whistle. Some boxes can be operated by the passing public;
others need special keys. The box mechanism is usually of
the ratchet, step-by-step movement, familiar in district

Edison's curiously practical, though imaginative, mind demanded
realities to work upon, things that belong to "human nature's daily food,"
and he soon harked back to telegraphy, a domain in which he was destined
to succeed, and over which he was to reign supreme as an inventor. He did
not, however, neglect chemistry, but indulged his tastes in that direction
freely, although we have no record that this work was anything more, at that
time, than the carrying out of experiments outlined in the books. The
foundations were being laid for the remarkable chemical knowledge that
later on grappled successfully with so many knotty problems in the realm of
chemistry; notably with the incandescent lamp and the storage battery. Of

Page 80
one incident in his chemical experiments he tells the following story: "I had
read in a scientific paper the method of making nitroglycerine, and was so
fired by the wonderful properties it was said to possess, that I determined to
make some of the compound. We tested what we considered a very small
quantity, but this produced such terrible and unexpected results that we
became alarmed, the fact dawning upon us that we had a very large white
elephant in our possession. At 6 A.M. I put the explosive into a sarsaparilla
bottle, tied a string to it, wrapped it in a paper, and gently let it down into
the sewer, corner of State and Washington Streets." The associate in this
was a man whom he had found endeavoring to make electrical apparatus for
sleight-of-hand performances.
In the Boston telegraph office at that time, as perhaps at others, there
were operators studying to enter college; possibly some were already in
attendance at Harvard University. This condition was not unusual at one
time; the first electrical engineer graduated from Columbia University, New
York, followed up his studies while a night operator, and came out
brilliantly at the head of his class. Edison says of these scholars that they
paraded their knowledge rather freely, and that it was his delight to go to the
second-hand book stores on Cornhill and study up questions which he could
spring upon them when he got an occasion. With those engaged on night
duty he got midnight lunch from an old Irishman called "the Cake Man,"
who appeared regularly with his wares at 12 midnight. "The office was on
the ground floor, and had been a restaurant previous to its occupation by the
Western Union Telegraph Company. It was literally loaded with
cockroaches, which lived between the wall and the board running around
the room at the floor, and which came after the lunch. These were such a
bother on my table that I pasted two strips of tinfoil on the wall at my desk,
connecting one piece to the positive pole of the big battery supplying
current to the wires and the negative pole to the other strip. The
cockroaches moving up on the wall would pass over the strips. The moment
they got their legs across both strips there was a flash of light and the
cockroaches went into gas. This automatic electrocuting device attracted so
much attention, and got half a column in an evening paper, that the manager
made me stop it." The reader will remember that a similar plan of campaign
against rats was carried out by Edison while in the West.
About this time Edison had a narrow escape from injury that might easily
have shortened his career, and he seems to have provoked the trouble more

About this time Edison had a narrow escape from injury that might easily

Page 81
or less innocently by using a little elementary chemistry. "After being in
Boston several months," he says, "working New York wire No. 1, I was
requested to work the press wire, called the 'milk route,' as there were so
many towns on it taking press simultaneously. New York office had
reported great delays on the wire, due to operators constantly interrupting,
or 'breaking,' as it was called, to have words repeated which they had failed
to get; and New York claimed that Boston was one of the worst offenders. It
was a rather hard position for me, for if I took the report without breaking,
it would prove the previous Boston operator incompetent. The results made
the operator have some hard feelings against me. He was put back on the
wire, and did much better after that. It seems that the office boy was down
on this man. One night he asked me if I could tell him how to fix a key so
that it would not 'break,' even if the circuit-breaker was open, and also so
that it could not be easily detected. I told him to jab a penful of ink on the
platinum points, as there was sugar enough to make it sufficiently thick to
hold up when the operator tried to break—the current still going through the
ink so that he could not break.
"The next night about 1 A.M. this operator, on the press wire, while I was
standing near a House printer studying it, pulled out a glass insulator, then
used upside down as a substitute for an ink-bottle, and threw it with great
violence at me, just missing my head. It would certainly have killed me if it
had not missed. The cause of the trouble was that this operator was doing
the best he could not to break, but being compelled to, opened his key and
found he couldn't. The press matter came right along, and he could not stop
it. The office boy had put the ink in a few minutes before, when the
operator had turned his head during a lull. He blamed me instinctively as
the cause of the trouble. Later on we became good friends. He took his
meals at the same emaciator that I did. His main object in life seemed to be
acquiring the art of throwing up wash-pitchers and catching them without
breaking them. About one-third of his salary was used up in paying for
pitchers."
One day a request reached the Western Union Telegraph office in Boston,
from the principal of a select school for young ladies, to the effect that she
would like some one to be sent up to the school to exhibit and describe the
Morse telegraph to her "children." There has always been a warm interest in

barely a mile from the birthplace of Franklin, and this request for a little
Page 82
lecture on Morse's telegraph was quite natural. Edison, who was always
ready to earn some extra money for his experiments, and was already
known as the best-informed operator in the office, accepted the invitation.
What happened is described by Adams as follows: "We gathered up a
couple of sounders, a battery, and sonic wire, and at the appointed time
called on her to do the stunt. Her school-room was about twenty by twenty
feet, not including a small platform. We rigged up the line between the two
ends of the room, Edison taking the stage while I was at the other end of the
room. All being in readiness, the principal was told to bring in her children.
The door opened and in came about twenty young ladies elegantly gowned,
not one of whom was under seventeen. When Edison saw them I thought he
would faint. He called me on the line and asked me to come to the stage and
explain the mysteries of the Morse system. I replied that I thought he was in
the right place, and told him to get busy with his talk on dots and dashes.
Always modest, Edison was so overcome he could hardly speak, but he
managed to say, finally, that as his friend Mr. Adams was better equipped
with cheek than he was, we would change places, and he would do the
demonstrating while I explained the whole thing. This caused the bevy to
turn to see where the lecturer was. I went on the stage, said something, and
we did some telegraphing over the line. I guess it was satisfactory; we got
the money, which was the main point to us." Edison tells the story in a
similar manner, but insists that it was he who saved the situation. "I
managed to say that I would work the apparatus, and Mr. Adams would
make the explanations. Adams was so embarrassed that he fell over an
ottoman. The girls tittered, and this increased his embarrassment until he
couldn't say a word. The situation was so desperate that for a reason I never
could explain I started in myself and talked and explained better than I ever
did before or since. I can talk to two or three persons; but when there are
more they radiate some unknown form of influence which paralyzes my
vocal cords. However, I got out of this scrape, and many times afterward
when I chanced with other operators to meet some of the young ladies on
their way home from school, they would smile and nod, much to the
mystification of the operators, who were ignorant of this episode."
Another amusing story of this period of impecuniosity and financial
strain is told thus by Edison: "My friend Adams was working in the
Franklin Telegraph Company, which competed with the Western Union.
Adams was laid off, and as his financial resources had reached absolute

known as the best-informed operator in the office, accepted the invitation.

Another amusing story of this period of impecuniosity and financial
strain is told thus by Edison: "My friend Adams was working in the
Franklin Telegraph Company, which competed with the Western Union.
Adams was laid off, and as his financial resources had reached absolute
Page 83
zero centigrade, I undertook to let him sleep in my hall bedroom. I
generally had hall bedrooms, because they were cheap and I needed money
to buy apparatus. I also had the pleasure of his genial company at the
boarding-house about a mile distant, but at the sacrifice of some apparatus.
One morning, as we were hastening to breakfast, we came into Tremont
Row, and saw a large crowd in front of two small 'gents' furnishing goods
stores. We stopped to ascertain the cause of the excitement. One store put
up a paper sign in the display window which said: 'Three-hundred pairs of
stockings received this day, five cents a pair—no connection with the store
next door.' Presently the other store put up a sign stating they had received
three hundred pairs, price three cents per pair, and stated that they had no
connection with the store next door. Nobody went in. The crowd kept
increasing. Finally, when the price had reached three pairs for one cent,
Adams said to me: 'I can't stand this any longer; give me a cent.' I gave him
a nickel, and he elbowed his way in; and throwing the money on the
counter, the store being filled with women clerks, he said: 'Give me three
pairs.' The crowd was breathless, and the girl took down a box and drew out
three pairs of baby socks. 'Oh!' said Adams, 'I want men's size.' 'Well, sir,
we do not permit one to pick sizes for that amount of money.' And the
crowd roared; and this broke up the sales."
It has generally been supposed that Edison did not take up work on the
stock ticker until after his arrival a little later in New York; but he says:
"After the vote-recorder I invented a stock ticker, and started a ticker
service in Boston; had thirty or forty subscribers, and operated from a room
over the Gold Exchange. This was about a year after Callahan started in
New York." To say the least, this evidenced great ability and enterprise on
the part of the youth. The dealings in gold during the Civil War and after its
close had brought gold indicators into use, and these had soon been
followed by "stock tickers," the first of which was introduced in New York
in 1867. The success of this new but still primitively crude class of
apparatus was immediate. Four manufacturers were soon busy trying to
keep pace with the demands for it from brokers; and the Gold & Stock
Telegraph Company formed to exploit the system soon increased its capital
from $200,000 to $300,000, paying 12 per cent. dividends on the latter
amount. Within its first year the capital was again increased to $1,000,000,
and dividends of 10 per cent. were paid easily on that sum also. It is
needless to say that such facts became quickly known among the operators,

needless to say that such facts became quickly known among the operators,
Page 84
from whose ranks, of course, the new employees were enlisted; and it was a
common ambition among the more ingenious to produce a new ticker. From
the beginning, each phase of electrical development—indeed, each step in
mechanics—has been accompanied by the well-known phenomenon of
invention; namely, the attempt of the many to perfect and refine and even
re-invent where one or two daring spirits have led the way. The figures of
capitalization and profit just mentioned were relatively much larger in the
sixties than they are to-day; and to impressionable young operators they
spelled illimitable wealth. Edison was, how ever, about the only one in
Boston of whom history makes record as achieving any tangible result in
this new art; and he soon longed for the larger telegraphic opportunity of
New York. His friend, Milt Adams, went West with quenchless zest for that
kind of roving life and aimless adventure of which the serious minded
Edison had already had more than enough. Realizing that to New York he
must look for further support in his efforts, Edison, deep in debt for his
embryonic inventions, but with high hope and courage, now made the next
momentous step in his career. He was far riper in experience and practice of
his art than any other telegrapher of his age, and had acquired, moreover, no
little knowledge of the practical business of life. Note has been made above
of his invention of a stock ticker in Boston, and of his establishing a stock-
quotation circuit. This was by no means all, and as a fitting close to this
chapter he may be quoted as to some other work and its perils in
experimentation: "I also engaged in putting up private lines, upon which I
used an alphabetical dial instrument for telegraphing between business
establishments, a forerunner of modern telephony. This instrument was very
simple and practical, and any one could work it after a few minutes'
explanation. I had these instruments made at Mr. Hamblet's, who had a little
shop where he was engaged in experimenting with electric clocks. Mr.
Hamblet was the father and introducer in after years of the Western Union
Telegraph system of time distribution. My laboratory was the headquarters
for the men, and also of tools and supplies for those private lines. They
were put up cheaply, as I used the roofs of houses, just as the Western
Union did. It never occurred to me to ask permission from the owners; all
we did was to go to the store, etc., say we were telegraph men, and wanted
to go up to the wires on the roof; and permission was always granted.

break the circuit. I shut my eyes and pulled, but the nitric acid splashed all
over my face and ran down my back. I rushed to a sink, which was only
half big enough, and got in as well as I could and wiggled around for
several minutes to permit the water to dilute the acid and stop the pain. My

CHAPTER VII
THE STOCK TICKER
"THE letters and figures used in the language of the tape," said a well-
known Boston stock speculator, "are very few, but they spell ruin in ninety-
nine million ways." It is not to be inferred, however, that the modern stock
ticker has anything to do with the making or losing of fortunes. There were
regular daily stock-market reports in London newspapers in 1825, and New
York soon followed the example. As far back as 1692, Houghton issued in
London a weekly review of financial and commercial transactions, upon
which Macaulay based the lively narrative of stock speculation in the
seventeenth century, given in his famous history. That which the ubiquitous
stock ticker has done is to give instantaneity to the news of what the stock
market is doing, so that at every minute, thousands of miles apart, brokers,
investors, and gamblers may learn the exact conditions. The existence of
such facilities is to be admired rather than deplored. News is vital to Wall
Street, and there is no living man on whom the doings in Wall Street are
without effect. The financial history of the United States and of the world,
as shown by the prices of government bonds and general securities, has
been told daily for forty years on these narrow strips of paper tape, of which
thousands of miles are run yearly through the "tickers" of New York alone.
It is true that the record of the chattering little machine, made in cabalistic
abbreviations on the tape, can drive a man suddenly to the very verge of
insanity with joy or despair; but if there be blame for that, it attaches to the
American spirit of speculation and not to the ingenious mechanism which
reads and registers the beating of the financial pulse.
Edison came first to New York in 1868, with his early stock printer,
which he tried unsuccessfully to sell. He went back to Boston, and quite
undismayed got up a duplex telegraph. "Toward the end of my stay in
Boston," he says, "I obtained a loan of money, amounting to $800, to build
a peculiar kind of duplex telegraph for sending two messages over a single
wire simultaneously. The apparatus was built, and I left the Western Union
employ and went to Rochester, New York, to test the apparatus on the lines

Edison came first to New York in 1868, with his early stock printer,
which he tried unsuccessfully to sell. He went back to Boston, and quite
undismayed got up a duplex telegraph. "Toward the end of my stay in
Boston," he says, "I obtained a loan of money, amounting to $800, to build
a peculiar kind of duplex telegraph for sending two messages over a single
wire simultaneously. The apparatus was built, and I left the Western Union
employ and went to Rochester, New York, to test the apparatus on the lines
Page 87
of the Atlantic & Pacific Telegraph between that city and New York. But the
assistant at the other end could not be made to understand anything,
notwithstanding I had written out a very minute description of just what to
do. After trying for a week I gave it up and returned to New York with but a
few cents in my pocket." Thus he who has never speculated in a stock in his
life was destined to make the beginnings of his own fortune by providing
for others the apparatus that should bring to the eye, all over a great city, the
momentary fluctuations of stocks and bonds. No one could have been in
direr poverty than he when the steamboat landed him in New York in 1869.
He was in debt, and his few belongings in books and instruments had to be
left behind. He was not far from starving. Mr. W. S. Mallory, an associate of
many years, quotes directly from him on this point: "Some years ago we
had a business negotiation in New York which made it necessary for Mr.
Edison and me to visit the city five or six times within a comparatively
short period. It was our custom to leave Orange about 11 A.M., and on
arrival in New York to get our lunch before keeping the appointments,
which were usually made for two o'clock. Several of these lunches were had
at Delmonico's, Sherry's, and other places of similar character, but one day,
while en route, Mr. Edison said: 'I have been to lunch with you several
times; now to-day I am going to take you to lunch with me, and give you
the finest lunch you ever had.' When we arrived in Hoboken, we took the
downtown ferry across the Hudson, and when we arrived on the Manhattan
side Mr. Edison led the way to Smith & McNell's, opposite Washington
Market, and well known to old New Yorkers. We went inside and as soon as
the waiter appeared Mr. Edison ordered apple dumplings and a cup of
coffee for himself. He consumed his share of the lunch with the greatest
possible pleasure. Then, as soon as he had finished, he went to the cigar
counter and purchased cigars. As we walked to keep the appointment he
gave me the following reminiscence: When he left Boston and decided to
come to New York he had only money enough for the trip. After leaving the
boat his first thought was of breakfast; but he was without money to obtain
it. However, in passing a wholesale tea-house he saw a man tasting tea, so
he went in and asked the 'taster' if he might have some of the tea. This the
man gave him, and thus he obtained his first breakfast in New York. He
knew a telegraph operator here, and on him he depended for a loan to tide
him over until such time as he should secure a position. During the day he
succeeded in locating this operator, but found that he also was out of a job,
assistant at the other end could not be made to understand anything,
notwithstanding I had written out a very minute description of just what to
do. After trying for a week I gave it up and returned to New York with but a
few cents in my pocket." Thus he who has never speculated in a stock in his

succeeded in locating this operator, but found that he also was out of a job,
Page 88
and that the best he could do was to loan him one dollar, which he did. This
small sum of money represented both food and lodging until such time as
work could be obtained. Edison said that as the result of the time consumed
and the exercise in walking while he found his friend, he was extremely
hungry, and that he gave most serious consideration as to what he should
buy in the way of food, and what particular kind of food would be most
satisfying and filling. The result was that at Smith & McNell's he decided
on apple dumplings and a cup of coffee, than which he never ate anything
more appetizing. It was not long before he was at work and was able to live
in a normal manner."
During the Civil War, with its enormous increase in the national debt and
the volume of paper money, gold had gone to a high premium; and, as ever,
by its fluctuations in price the value of all other commodities was
determined. This led to the creation of a "Gold Room" in Wall Street, where
the precious metal could be dealt in; while for dealings in stocks there also
existed the "Regular Board," the "Open Board," and the "Long Room."
Devoted to one, but the leading object of speculation, the "Gold Room" was
the very focus of all the financial and gambling activity of the time, and its
quotations governed trade and commerce. At first notations in chalk on a
blackboard sufficed, but seeing their inadequacy, Dr. S. S. Laws, vice-
president and actual presiding officer of the Gold Exchange, devised and
introduced what was popularly known as the "gold indicator." This
exhibited merely the prevailing price of gold; but as its quotations changed
from instant to instant, it was in a most literal sense "the cynosure of
neighboring eyes." One indicator looked upon the Gold Room; the other
opened toward the street. Within the exchange the face could easily be seen
high up on the west wall of the room, and the machine was operated by Mr.
Mersereau, the official registrar of the Gold Board.
Doctor Laws, who afterward became President of the State University of
Missouri, was an inventor of unusual ability and attainments. In his early
youth he had earned his livelihood in a tool factory; and, apparently with
his savings, he went to Princeton, where he studied electricity under no less
a teacher than the famous Joseph Henry. At the outbreak of the war in 1861
he was president of one of the Presbyterian synodical colleges in the South,
whose buildings passed into the hands of the Government. Going to Europe,
he returned to New York in 1863, and, becoming interested with a relative
in financial matters, his connection with the Gold Exchange soon followed,

he returned to New York in 1863, and, becoming interested with a relative
in financial matters, his connection with the Gold Exchange soon followed,
Page 89
when it was organized. The indicating mechanism he now devised was
electrical, controlled at central by two circuit-closing keys, and was a
prototype of all the later and modern step-by-step printing telegraphs, upon
which the distribution of financial news depends. The "fraction" drum of
the indicator could be driven in either direction, known as the advance and
retrograde movements, and was divided and marked in eighths. It geared
into a "unit" drum, just as do speed-indicators and cyclometers. Four
electrical pulsations were required to move the drum the distance between
the fractions. The general operation was simple, and in normally active
times the mechanism and the registrar were equal to all emergencies. But it
is obvious that the record had to be carried away to the brokers' offices and
other places by messengers; and the delay, confusion, and mistakes soon
suggested to Doctor Laws the desirability of having a number of indicators
at such scattered points, operated by a master transmitter, and dispensing
with the regiments of noisy boys. He secured this privilege of distribution,
and, resigning from the exchange, devoted his exclusive attention to the
"Gold Reporting Telegraph," which he patented, and for which, at the end
of 1866, he had secured fifty subscribers. His indicators were small oblong
boxes, in the front of which was a long slot, allowing the dials as they
travelled past, inside, to show the numerals constituting the quotation; the
dials or wheels being arranged in a row horizontally, overlapping each
other, as in modern fare registers which are now seen on most trolley cars.
It was not long before there were three hundred subscribers; but the very
success of this device brought competition and improvement. Mr. E. A.
Callahan, an ingenious printing-telegraph operator, saw that there were
unexhausted possibilities in the idea, and his foresight and inventiveness
made him the father of the "ticker," in connection with which he was thus,
like Laws, one of the first to grasp and exploit the underlying principle of
the "central station" as a universal source of supply. The genesis of his
invention Mr. Callahan has told in an interesting way: "In 1867, on the site
of the present Mills Building on Broad Street, opposite the Stock Exchange
of today, was an old building which had been cut up to subserve the
necessities of its occupants, all engaged in dealing in gold and stocks. It had
one main entrance from the street to a hallway, from which entrance to the
offices of two prominent broker firms was obtained. Each firm had its own
army of boys, numbering from twelve to fifteen, whose duties were to
ascertain the latest quotations from the different exchanges. Each boy
electrical, controlled at central by two circuit-closing keys, and was a
prototype of all the later and modern step-by-step printing telegraphs, upon
which the distribution of financial news depends. The "fraction" drum of
the indicator could be driven in either direction, known as the advance and
retrograde movements, and was divided and marked in eighths. It geared
into a "unit" drum, just as do speed-indicators and cyclometers. Four
electrical pulsations were required to move the drum the distance between
the fractions. The general operation was simple, and in normally active
times the mechanism and the registrar were equal to all emergencies. But it
is obvious that the record had to be carried away to the brokers' offices and
other places by messengers; and the delay, confusion, and mistakes soon
suggested to Doctor Laws the desirability of having a number of indicators
at such scattered points, operated by a master transmitter, and dispensing
with the regiments of noisy boys. He secured this privilege of distribution,
and, resigning from the exchange, devoted his exclusive attention to the

one main entrance from the street to a hallway, from which entrance to the
offices of two prominent broker firms was obtained. Each firm had its own
army of boys, numbering from twelve to fifteen, whose duties were to
ascertain the latest quotations from the different exchanges. Each boy
Page 90
devoted his attention to some particularly active stock. Pushing each other
to get into these narrow quarters, yelling out the prices at the door, and
pushing back for later ones, the hustle made this doorway to me a most
undesirable refuge from an April shower. I was simply whirled into the
street. I naturally thought that much of this noise and confusion might be
dispensed with, and that the prices might be furnished through some system
of telegraphy which would not require the employment of skilled operators.
The conception of the stock ticker dates from this incident."
Mr. Callahan's first idea was to distribute gold quotations, and to this end
he devised an "indicator." It consisted of two dials mounted separately, each
revolved by an electromagnet, so that the desired figures were brought to an
aperture in the case enclosing the apparatus, as in the Laws system. Each
shaft with its dial was provided with two ratchet wheels, one the reverse of
the other. One was used in connection with the propelling lever, which was
provided with a pawl to fit into the teeth of the reversed ratchet wheel on its
forward movement. It was thus made impossible for either dial to go by
momentum beyond its limit. Learning that Doctor Laws, with the skilful aid
of F. L. Pope, was already active in the same direction, Mr. Callahan, with
ready wit, transformed his indicator into a "ticker" that would make a
printed record. The name of the "ticker" came through the casual remark of
an observer to whom the noise was the most striking feature of the
mechanism. Mr. Callahan removed the two dials, and, substituting type
wheels, turned the movements face to face, so that each type wheel could
imprint its characters upon a paper tape in two lines. Three wires stranded
together ran from the central office to each instrument. Of these one
furnished the current for the alphabet wheel, one for the figure wheel, and
one for the mechanism that took care of the inking and printing on the tape.
Callahan made the further innovation of insulating his circuit wires,
although the cost was then forty times as great as that of bare wire. It will
be understood that electromagnets were the ticker's actuating agency. The
ticker apparatus was placed under a neat glass shade and mounted on a
shelf. Twenty-five instruments were energized from one circuit, and the
quotations were supplied from a "central" at 18 New Street. The Gold &
Stock Telegraph Company was promptly organized to supply to brokers the
system, which was very rapidly adopted throughout the financial district of
New York, at the southern tip of Manhattan Island. Quotations were
transmitted by the Morse telegraph from the floor of the Stock Exchange to

It was at this juncture that Edison reached New York, and according to
his own statement found shelter at night in the battery-room of the Gold
Indicator Company, having meantime applied for a position as operator
with the Western Union. He had to wait a few days, and during this time he
seized the opportunity to study the indicators and the complicated general
transmitter in the office, controlled from the keyboard of the operator on the
floor of the Gold Exchange. What happened next has been the basis of
many inaccurate stories, but is dramatic enough as told in Mr. Edison's own
version: "On the third day of my arrival and while sitting in the office, the
complicated general instrument for sending on all the lines, and which
made a very great noise, suddenly came to a stop with a crash. Within two
minutes over three hundred boys—a boy from every broker in the street—
rushed up-stairs and crowded the long aisle and office, that hardly had room
for one hundred, all yelling that such and such a broker's wire was out of
order and to fix it at once. It was pandemonium, and the man in charge
became so excited that he lost control of all the knowledge he ever had. I
went to the indicator, and, having studied it thoroughly, knew where the
trouble ought to be, and found it. One of the innumerable contact springs
had broken off and had fallen down between the two gear wheels and
stopped the instrument; but it was not very noticeable. As I went out to tell
the man in charge what the matter was, Doctor Laws appeared on the scene,
the most excited person I had seen. He demanded of the man the cause of
the trouble, but the man was speechless. I ventured to say that I knew what
the trouble was, and he said, 'Fix it! Fix it! Be quick!' I removed the spring
and set the contact wheels at zero; and the line, battery, and inspecting men
all scattered through the financial district to set the instruments. In about
two hours things were working again. Doctor Laws came in to ask my name
and what I was doing. I told him, and he asked me to come to his private
office the following day. His office was filled with stacks of books all
relating to metaphysics and kindred matters. He asked me a great many
questions about the instruments and his system, and I showed him how he
could simplify things generally. He then requested that I should call next
day. On arrival, he stated at once that he had decided to put me in charge of
the whole plant, and that my salary would be $300 per month! This was
such a violent jump from anything I had ever seen before, that it rather

determined to try and live up to that salary if twenty hours a day of hard
work would do it. I kept this position, made many improvements, devised
several stock tickers, until the Gold & Stock Telegraph Company
consolidated with the Gold Indicator Company." Certainly few changes in
fortune have been more sudden and dramatic in any notable career than this
which thus placed an ill-clad, unkempt, half-starved, eager lad in a position
of such responsibility in days when the fluctuations in the price of gold at
every instant meant fortune or ruin to thousands.
Edison, barely twenty-one years old, was a keen observer of the stirring
events around him. "Wall Street" is at any time an interesting study, but it
was never at a more agitated and sensational period of its history than at
this time. Edison's arrival in New York coincided with an active speculation
in gold which may, indeed, be said to have provided him with occupation;
and was soon followed by the attempt of Mr. Jay Gould and his associates
to corner the gold market, precipitating the panic of Black Friday,
September 24, 1869. Securing its import duties in the precious metal and
thus assisting to create an artificial stringency in the gold market, the
Government had made it a practice to relieve the situation by selling a
million of gold each month. The metal was thus restored to circulation. In
some manner, President Grant was persuaded that general conditions and
the movement of the crops would be helped if the sale of gold were
suspended for a time; and, this put into effect, he went to visit an old friend
in Pennsylvania remote from railroads and telegraphs. The Gould pool had
acquired control of $10,000,000 in gold, and drove the price upward rapidly
from 144 toward their goal of 200. On Black Friday they purchased another
$28,000,000 at 160, and still the price went up. The financial and
commercial interests of the country were in panic; but the pool persevered
in its effort to corner gold, with a profit of many millions contingent on
success. Yielding to frantic requests, President Grant, who returned to
Washington, caused Secretary Boutwell, of the Treasury, to throw
$4,000,000 of gold into the market. Relief was instantaneous, the corner
was broken, but the harm had been done. Edison's remarks shed a vivid
side-light on this extraordinary episode: "On Black Friday," he says, "we
had a very exciting time with the indicators. The Gould and Fisk crowd had
cornered gold, and had run the quotations up faster than the indicator could
follow. The indicator was composed of several wheels; on the

Page 93
circumference of each wheel were the numerals; and one wheel had
fractions. It worked in the same way as an ordinary counter; one wheel
made ten revolutions, and at the tenth it advanced the adjacent wheel; and
this in its turn having gone ten revolutions, advanced the next wheel, and so
on. On the morning of Black Friday the indicator was quoting 150
premium, whereas the bids by Gould's agents in the Gold Room were 165
for five millions or any part. We had a paper-weight at the transmitter (to
speed it up), and by one o'clock reached the right quotation. The excitement
was prodigious. New Street, as well as Broad Street, was jammed with
excited people. I sat on the top of the Western Union telegraph booth to
watch the surging, crazy crowd. One man came to the booth, grabbed a
pencil, and attempted to write a message to Boston. The first stroke went
clear off the blank; he was so excited that he had the operator write the
message for him. Amid great excitement Speyer, the banker, went crazy and
it took five men to hold him; and everybody lost their head. The Western
Union operator came to me and said: 'Shake, Edison, we are O. K. We
haven't got a cent.' I felt very happy because we were poor. These occasions
are very enjoyable to a poor man; but they occur rarely."
There is a calm sense of detachment about this description that has been
possessed by the narrator even in the most anxious moments of his career.
He was determined to see all that could be seen, and, quitting his perch on
the telegraph booth, sought the more secluded headquarters of the pool
forces. "A friend of mine was an operator who worked in the office of
Belden & Company, 60 Broadway, which were headquarters for Fisk. Mr.
Gould was up-town in the Erie offices in the Grand Opera House. The firm
on Broad Street, Smith, Gould & Martin, was the other branch. All were
connected with wires. Gould seemed to be in charge, Fisk being the
executive down-town. Fisk wore a velvet corduroy coat and a very peculiar
vest. He was very chipper, and seemed to be light-hearted and happy.
Sitting around the room were about a dozen fine-looking men. All had the
complexion of cadavers. There was a basket of champagne. Hundreds of
boys were rushing in paying checks, all checks being payable to Belden &
Company. When James Brown, of Brown Brothers & Company, broke the
corner by selling five million gold, all payments were repudiated by Smith,
Gould & Martin; but they continued to receive checks at Belden &
Company's for some time, until the Street got wind of the game. There was
some kind of conspiracy with the Government people which I could not
fractions. It worked in the same way as an ordinary counter; one wheel
made ten revolutions, and at the tenth it advanced the adjacent wheel; and

make out, but I heard messages that opened my eyes as to the ramifications
of Wall Street. Gold fell to 132, and it took us all night to get the indicator
back to that quotation. All night long the streets were full of people. Every
broker's office was brilliantly lighted all night, and all hands were at work.
The clearing-house for gold had been swamped, and all was mixed up. No
one knew if he was bankrupt or not."
Edison in those days rather liked the modest coffee-shops, and mentions
visiting one. "When on the New York No. 1 wire, that I worked in Boston,
there was an operator named Jerry Borst at the other end. He was a first-
class receiver and rapid sender. We made up a scheme to hold this wire, so
he changed one letter of the alphabet and I soon got used to it; and finally
we changed three letters. If any operator tried to receive from Borst, he
couldn't do it, so Borst and I always worked together. Borst did less talking
than any operator I ever knew. Never having seen him, I went while in New
York to call upon him. I did all the talking. He would listen, stroke his
beard, and say nothing. In the evening I went over to an all-night lunch-
house in Printing House Square in a basement—Oliver's. Night editors,
including Horace Greeley, and Henry Raymond, of the New York Times,
took their midnight lunch there. When I went with Borst and another
operator, they pointed out two or three men who were then celebrated in the
newspaper world. The night was intensely hot and close. After getting our
lunch and upon reaching the sidewalk, Borst opened his mouth, and said:
'That's a great place; a plate of cakes, a cup of coffee, and a Russian bath,
for ten cents.' This was about fifty per cent. of his conversation for two
days."
The work of Edison on the gold-indicator had thrown him into close
relationship with Mr. Franklin L. Pope, the young telegraph engineer then
associated with Doctor Laws, and afterward a distinguished expert and
technical writer, who became President of the American Institute of
Electrical Engineers in 1886. Each recognized the special ability of the
other, and barely a week after the famous events of Black Friday the
announcement of their partnership appeared in the Telegrapher of October
1, 1869. This was the first "professional card," if it may be so described,
ever issued in America by a firm of electrical engineers, and is here
reproduced. It is probable that the advertisement, one of the largest in the
Telegrapher, and appearing frequently, was not paid for at full rates, as the
publisher, Mr. J. N. Ashley, became a partner in the firm, and not altogether
of Wall Street. Gold fell to 132, and it took us all night to get the indicator

Page 95
a "sleeping one" when it came to a division of profits, which at times were
considerable. In order to be nearer his new friend Edison boarded with Pope
at Elizabeth, New Jersey, for some time, living "the strenuous life" in the
performance of his duties. Associated with Pope and Ashley, he followed up
his work on telegraph printers with marked success. "While with them I
devised a printer to print gold quotations instead of indicating them. The
lines were started, and the whole was sold out to the Gold & Stock
Telegraph Company. My experimenting was all done in the small shop of a
Doctor Bradley, located near the station of the Pennsylvania Railroad in
Jersey City. Every night I left for Elizabeth on the 1 A.M. train, then walked
half a mile to Mr. Pope's house and up at 6 A.M. for breakfast to catch the 7
A.M. train. This continued all winter, and many were the occasions when I
was nearly frozen in the Elizabeth walk." This Doctor Bradley appears to
have been the first in this country to make electrical measurements of
precision with the galvanometer, but was an old-school experimenter who
would work for years on an instrument without commercial value. He was
also extremely irascible, and when on one occasion the connecting wire
would not come out of one of the binding posts of a new and costly
galvanometer, he jerked the instrument to the floor and then jumped on it.
He must have been, however, a man of originality, as evidenced by his
attempt to age whiskey by electricity, an attempt that has often since been
made. "The hobby he had at the time I was there," says Edison, "was the
aging of raw whiskey by passing strong electric currents through it. He had
arranged twenty jars with platinum electrodes held in place by hard rubber.
When all was ready, he filled the cells with whiskey, connected the battery,
locked the door of the small room in which they were placed, and gave
positive orders that no one should enter. He then disappeared for three days.
On the second day we noticed a terrible smell in the shop, as if from some
dead animal. The next day the doctor arrived and, noticing the smell, asked
what was dead. We all thought something had got into his whiskey-room
and died. He opened it and was nearly overcome. The hard rubber he used
was, of course, full of sulphur, and this being attacked by the nascent
hydrogen, had produced sulphuretted hydrogen gas in torrents, displacing
all of the air in the room. Sulphuretted hydrogen is, as is well known, the
gas given off by rotten eggs."
Another glimpse of this period of development is afforded by an
interesting article on the stock-reporting telegraph in the Electrical World of
considerable. In order to be nearer his new friend Edison boarded with Pope
at Elizabeth, New Jersey, for some time, living "the strenuous life" in the
performance of his duties. Associated with Pope and Ashley, he followed up
his work on telegraph printers with marked success. "While with them I

Jersey City. Every night I left for Elizabeth on the 1 A.M. train, then walked
half a mile to Mr. Pope's house and up at 6 A.M. for breakfast to catch the 7
A.M. train. This continued all winter, and many were the occasions when I
was nearly frozen in the Elizabeth walk." This Doctor Bradley appears to
have been the first in this country to make electrical measurements of
precision with the galvanometer, but was an old-school experimenter who
would work for years on an instrument without commercial value. He was
also extremely irascible, and when on one occasion the connecting wire
would not come out of one of the binding posts of a new and costly
galvanometer, he jerked the instrument to the floor and then jumped on it.
He must have been, however, a man of originality, as evidenced by his
attempt to age whiskey by electricity, an attempt that has often since been
made. "The hobby he had at the time I was there," says Edison, "was the
aging of raw whiskey by passing strong electric currents through it. He had
arranged twenty jars with platinum electrodes held in place by hard rubber.
When all was ready, he filled the cells with whiskey, connected the battery,
locked the door of the small room in which they were placed, and gave
positive orders that no one should enter. He then disappeared for three days.
On the second day we noticed a terrible smell in the shop, as if from some
dead animal. The next day the doctor arrived and, noticing the smell, asked
what was dead. We all thought something had got into his whiskey-room
and died. He opened it and was nearly overcome. The hard rubber he used
was, of course, full of sulphur, and this being attacked by the nascent
hydrogen, had produced sulphuretted hydrogen gas in torrents, displacing
all of the air in the room. Sulphuretted hydrogen is, as is well known, the
gas given off by rotten eggs."
Another glimpse of this period of development is afforded by an
interesting article on the stock-reporting telegraph in the Electrical World of
Page 96
March 4, 1899, by Mr. Ralph W. Pope, the well-known Secretary of the
American Institute of Electrical Engineers, who had as a youth an active
and intimate connection with that branch of electrical industry. In the course
of his article he mentions the curious fact that Doctor Laws at first, in
receiving quotations from the Exchanges, was so distrustful of the Morse
system that he installed long lines of speaking-tube as a more satisfactory
and safe device than a telegraph wire. As to the relations of that time Mr.
Pope remarks: "The rivalry between the two concerns resulted in
consolidation, Doctor Laws's enterprise being absorbed by the Gold &
Stock Telegraph Company, while the Laws stock printer was relegated to
the scrap-heap and the museum. Competition in the field did not, however,
cease. Messrs. Pope and Edison invented a one-wire printer, and started a
system of 'gold printers' devoted to the recording of gold quotations and
sterling exchange only. It was intended more especially for importers and
exchange brokers, and was furnished at a lower price than the indicator
service.... The building and equipment of private telegraph lines was also
entered upon. This business was also subsequently absorbed by the Gold &
Stock Telegraph Company, which was probably at this time at the height of
its prosperity. The financial organization of the company was peculiar and
worthy of attention. Each subscriber for a machine paid in $100 for the
privilege of securing an instrument. For the service he paid $25 weekly. In
case he retired or failed, he could transfer his 'right,' and employees were
constantly on the alert for purchasable rights, which could be disposed of at
a profit. It was occasionally worth the profit to convince a man that he did
not actually own the machine which had been placed in his office.... The
Western Union Telegraph Company secured a majority of its stock, and
Gen. Marshall Lefferts was elected president. A private-line department was
established, and the business taken over from Pope, Edison, and Ashley was
rapidly enlarged."
At this juncture General Lefferts, as President of the Gold & Stock
Telegraph Company, requested Edison to go to work on improving the stock
ticker, furnishing the money; and the well-known "Universal" ticker, in
wide-spread use in its day, was one result. Mr. Edison gives a graphic
picture of the startling effect on his fortunes: "I made a great many
inventions; one was the special ticker used for many years outside of New
York in the large cities. This was made exceedingly simple, as they did not
have the experts we had in New York to handle anything complicated. The

same ticker was used on the London Stock Exchange. After I had made a
great number of inventions and obtained patents, the General seemed
anxious that the matter should be closed up. One day I exhibited and
worked a successful device whereby if a ticker should get out of unison in a
broker's office and commence to print wild figures, it could be brought to
unison from the central station, which saved the labor of many men and
much trouble to the broker. He called me into his office, and said: 'Now,
young man, I want to close up the matter of your inventions. How much do
you think you should receive?' I had made up my mind that, taking into
consideration the time and killing pace I was working at, I should be
entitled to $5000, but could get along with $3000. When the psychological
moment arrived, I hadn't the nerve to name such a large sum, so I said:
'Well, General, suppose you make me an offer.' Then he said: 'How would
$40,000 strike you?' This caused me to come as near fainting as I ever got. I
was afraid he would hear my heart beat. I managed to say that I thought it
was fair. 'All right, I will have a contract drawn; come around in three days
and sign it, and I will give you the money.' I arrived on time, but had been
doing some considerable thinking on the subject. The sum seemed to be
very large for the amount of work, for at that time I determined the value by
the time and trouble, and not by what the invention was worth to others. I
thought there was something unreal about it. However, the contract was
handed to me. I signed without reading it." Edison was then handed the first
check he had ever received, one for $40,000 drawn on the Bank of New
York, at the corner of William and Wall Streets. On going to the bank and
passing in the check at the wicket of the paying teller, some brief remarks
were made to him, which in his deafness he did not understand. The check
was handed back to him, and Edison, fancying for a moment that in some
way he had been cheated, went outside "to the large steps to let the cold
sweat evaporate." He then went back to the General, who, with his
secretary, had a good laugh over the matter, told him the check must be
endorsed, and sent with him a young man to identify him. The ceremony of
identification performed with the paying teller, who was quite merry over
the incident, Edison was given the amount in bundles of small bills "until
there certainly seemed to be one cubic foot." Unaware that he was the
victim of a practical joke, Edison proceeded gravely to stow away the
money in his overcoat pockets and all his other pockets. He then went to
Newark and sat up all night with the money for fear it might be stolen.

Once more he sought help next morning, when the General laughed
heartily, and, telling the clerk that the joke must not be carried any further,
enabled him to deposit the currency in the bank and open an account.
Thus in an inconceivably brief time had Edison passed from poverty to
independence; made a deep impression as to his originality and ability on
important people, and brought out valuable inventions; lifting himself at
one bound out of the ruck of mediocrity, and away from the deadening
drudgery of the key. Best of all he was enterprising, one of the leaders and
pioneers for whom the world is always looking; and, to use his own
criticism of himself, he had "too sanguine a temperament to keep money in
solitary confinement." With quiet self-possession he seized his opportunity,
began to buy machinery, rented a shop and got work for it. Moving quickly
into a larger shop, Nos. 10 and 12 Ward Street, Newark, New Jersey, he
secured large orders from General Lefferts to build stock tickers, and
employed fifty men. As business increased he put on a night force, and was
his own foreman on both shifts. Half an hour of sleep three or four times in
the twenty-four hours was all he needed in those days, when one invention
succeeded another with dazzling rapidity, and when he worked with the
fierce, eruptive energy of a great volcano, throwing out new ideas
incessantly with spectacular effect on the arts to which they related. It has
always been a theory with Edison that we sleep altogether too much; but on
the other hand he never, until long past fifty, knew or practiced the slightest
moderation in work or in the use of strong coffee and black cigars. He has,
moreover, while of tender and kindly disposition, never hesitated to use
men up as freely as a Napoleon or Grant; seeing only the goal of a complete
invention or perfected device, to attain which all else must become
subsidiary. He gives a graphic picture of his first methods as a
manufacturer: "Nearly all my men were on piece work, and I allowed them
to make good wages, and never cut until the pay became absurdly high as
they got more expert. I kept no books. I had two hooks. All the bills and
accounts I owed I jabbed on one hook; and memoranda of all owed to
myself I put on the other. When some of the bills fell due, and I couldn't
deliver tickers to get a supply of money, I gave a note. When the notes were
due, a messenger came around from the bank with the note and a protest
pinned to it for $1.25. Then I would go to New York and get an advance, or
pay the note if I had the money. This method of giving notes for my
accounts and having all notes protested I kept up over two years, yet my

Page 99
credit was fine. Every store I traded with was always glad to furnish goods,
perhaps in amazed admiration of my system of doing business, which was
certainly new." After a while Edison got a bookkeeper, whose vagaries
made him look back with regret on the earlier, primitive method. "The first
three months I had him go over the books to find out how much we had
made. He reported $3000. I gave a supper to some of my men to celebrate
this, only to be told two days afterward that he had made a mistake, and that
we had lost $500; and then a few days after that he came to me again and
said he was all mixed up, and now found that we had made over $7000."
Edison changed bookkeepers, but never thereafter counted anything real
profit until he had paid all his debts and had the profits in the bank.
The factory work at this time related chiefly to stock tickers, principally
the "Universal," of which at one time twelve hundred were in use. Edison's
connection with this particular device was very close while it lasted. In a
review of the ticker art, Mr. Callahan stated, with rather grudging praise,
that "a ticker at the present time (1901) would be considered as
impracticable and unsalable if it were not provided with a unison device,"
and he goes on to remark: "The first unison on stock tickers was one used
on the Laws printer. [2] It was a crude and unsatisfactory piece of
mechanism and necessitated doubling of the battery in order to bring it into
action. It was short-lived. The Edison unison comprised a lever with a free
end travelling in a spiral or worm on the type-wheel shaft until it met a pin
at the end of the worm, thus obstructing the shaft and leaving the type-
wheels at the zero-point until released by the printing lever. This device is
too well known to require a further description. It is not applicable to any
instrument using two independently moving type-wheels; but on nearly if
not all other instruments will be found in use." The stock ticker has enjoyed
the devotion of many brilliant inventors—G. M. Phelps, H. Van
Hoevenbergh, A. A. Knudson, G. B. Scott, S. D. Field, John Burry—and
remains in extensive use as an appliance for which no substitute or
competitor has been found. In New York the two great stock exchanges
have deemed it necessary to own and operate a stock-ticker service for the
sole benefit of their members; and down to the present moment the process
of improvement has gone on, impelled by the increasing volume of business
to be reported. It is significant of Edison's work, now dimmed and overlaid
by later advances, that at the very outset he recognized the vital importance
of interchangeability in the construction of this delicate and sensitive

by later advances, that at the very outset he recognized the vital importance
of interchangeability in the construction of this delicate and sensitive
Page 100
apparatus. But the difficulties of these early days were almost
insurmountable. Mr. R. W. Pope says of the "Universal" machines that they
were simple and substantial and generally satisfactory, but adds: "These
instruments were supposed to have been made with interchangeable parts;
but as a matter of fact the instances in which these parts would fit were very
few. The instruction-book prepared for the use of inspectors stated that 'The
parts should not be tinkered nor bent, as they are accurately made and
interchangeable.' The difficulties encountered in fitting them properly
doubtless gave rise to a story that Mr. Edison had stated that there were
three degrees of interchangeability. This was interpreted to mean: First, the
parts will fit; second, they will almost fit; third, they do not fit, and can't be
made to fit."
[Footnote 2: This I invented as well.—T. A. E.]
This early shop affords an illustration of the manner in which Edison has
made a deep impression on the personnel of the electrical arts. At a single
bench there worked three men since rich or prominent. One was Sigmund
Bergmann, for a time partner with Edison in his lighting developments in
the United States, and now head and principal owner of electrical works in
Berlin employing ten thousand men. The next man adjacent was John
Kruesi, afterward engineer of the great General Electric Works at
Schenectady. A third was Schuckert, who left the bench to settle up his
father's little estate at Nuremberg, stayed there and founded electrical
factories, which became the third largest in Germany, their proprietor dying
very wealthy. "I gave them a good training as to working hours and
hustling," says their quondam master; and this is equally true as applied to
many scores of others working in companies bearing the Edison name or
organized under Edison patents. It is curiously significant in this connection
that of the twenty-one presidents of the national society, the American
Institute of Electrical Engineers, founded in 1884, eight have been
intimately associated with Edison—namely, Norvin Green and F. L. Pope,
as business colleagues of the days of which we now write; while Messrs.
Frank J. Sprague, T. C. Martin, A. E. Kennelly, S. S. Wheeler, John W. Lieb,
Jr., and Louis A. Ferguson have all been at one time or another in the
Edison employ. The remark was once made that if a famous American

CHAPTER VIII
AUTOMATIC, DUPLEX, AND QUADRUPLEX
TELEGRAPHY
WORK of various kinds poured in upon the young manufacturer, busy
also with his own schemes and inventions, which soon began to follow so
many distinct lines of inquiry that it ceases to be easy or necessary for the
historian to treat them all in chronological sequence. Some notion of his
ceaseless activity may be formed from the fact that he started no fewer than
three shops in Newark during 1870-71, and while directing these was also
engaged by the men who controlled the Automatic Telegraph Company of
New York, which had a circuit to Washington, to help it out of its
difficulties. "Soon after starting the large shop (10 and 12 Ward Street,
Newark), I rented shop-room to the inventor of a new rifle. I think it was
the Berdan. In any event, it was a rifle which was subsequently adopted by
the British Army. The inventor employed a tool-maker who was the finest
and best tool-maker I had ever seen. I noticed that he worked pretty near the
whole of the twenty-four hours. This kind of application I was looking for.
He was getting $21.50 per week, and was also paid for overtime. I asked
him if he could run the shop. 'I don't know; try me!' he said. 'All right, I will
give you $60 per week to run both shifts.' He went at it. His executive
ability was greater than that of any other man I have yet seen. His memory
was prodigious, conversation laconic, and movements rapid. He doubled
the production inside three months, without materially increasing the pay-
roll, by increasing the cutting speeds of tools, and by the use of various
devices. When in need of rest he would lie down on a work-bench, sleep
twenty or thirty minutes, and wake up fresh. As this was just what I could
do, I naturally conceived a great pride in having such a man in charge of my
work. But almost everything has trouble connected with it. He disappeared
one day, and although I sent men everywhere that it was likely he could be
found, he was not discovered. After two weeks he came into the factory in a
terrible condition as to clothes and face. He sat down and, turning to me,
said: 'Edison, it's no use, this is the third time; I can't stand prosperity. Put

Page 103
my salary back and give me a job.' I was very sorry to learn that it was
whiskey that spoiled such a career. I gave him an inferior job and kept him
for a long time."
Edison had now entered definitely upon that career as an inventor which
has left so deep an imprint on the records of the United States Patent Office,
where from his first patent in 1869 up to the summer of 1910 no fewer than
1328 separate patents have been applied for in his name, averaging thirty-
two every year, and one about every eleven days; with a substantially
corresponding number issued. The height of this inventive activity was
attained about 1882, in which year no fewer than 141 patents were applied
for, and seventy-five granted to him, or nearly nine times as many as in
1876, when invention as a profession may be said to have been adopted by
this prolific genius. It will be understood, of course, that even these figures
do not represent the full measure of actual invention, as in every process
and at every step there were many discoveries that were not brought to
patent registration, but remained "trade secrets." And furthermore, that in
practically every case the actual patented invention followed from one to a
dozen or more gradually developing forms of the same idea.
An Englishman named George Little had brought over a system of
automatic telegraphy which worked well on a short line, but was a failure
when put upon the longer circuits for which automatic methods are best
adapted. The general principle involved in automatic or rapid telegraphs,
except the photographic ones, is that of preparing the message in advance,
for dispatch, by perforating narrow strips of paper with holes—work which
can be done either by hand-punches or by typewriter apparatus. A certain
group of perforations corresponds to a Morse group of dots and dashes for a
letter of the alphabet. When the tape thus made ready is run rapidly through
a transmitting machine, electrical contact occurs wherever there is a
perforation, permitting the current from the battery to flow into the line and
thus transmit signals correspondingly. At the distant end these signals are
received sometimes on an ink-writing recorder as dots and dashes, or even
as typewriting letters; but in many of the earlier systems, like that of Bain,
the record at the higher rates of speed was effected by chemical means, a
tell-tale stain being made on the travelling strip of paper by every spurt of
incoming current. Solutions of potassium iodide were frequently used for
this purpose, giving a sharp, blue record, but fading away too rapidly.
whiskey that spoiled such a career. I gave him an inferior job and kept him
for a long time."
Edison had now entered definitely upon that career as an inventor which
has left so deep an imprint on the records of the United States Patent Office,
where from his first patent in 1869 up to the summer of 1910 no fewer than
1328 separate patents have been applied for in his name, averaging thirty-
two every year, and one about every eleven days; with a substantially
corresponding number issued. The height of this inventive activity was

The Little system had perforating apparatus operated by electromagnets;
its transmitting machine was driven by a small electromagnetic motor; and
the record was made by electrochemical decomposition, the writing
member being a minute platinum roller instead of the more familiar iron
stylus. Moreover, a special type of wire had been put up for the single
circuit of two hundred and eighty miles between New York and
Washington. This is believed to have been the first "compound" wire made
for telegraphic or other signalling purposes, the object being to secure
greater lightness with textile strength and high conductivity. It had a steel
core, with a copper ribbon wound spirally around it, and tinned to the core
wire. But the results obtained were poor, and in their necessity the parties in
interest turned to Edison.
Mr. E. H. Johnson tells of the conditions: "Gen. W. J. Palmer and some
New York associates had taken up the Little automatic system and had
expended quite a sum in its development, when, thinking they had reduced
it to practice, they got Tom Scott, of the Pennsylvania Railroad to send his
superintendent of telegraph over to look into and report upon it. Of course
he turned it down. The syndicate was appalled at this report, and in this
extremity General Palmer thought of the man who had impressed him as
knowing it all by the telling of telegraphic tales as a means of whiling away
lonesome hours on the plains of Colorado, where they were associated in
railroad-building. So this man—it was I—was sent for to come to New
York and assuage their grief if possible. My report was that the system was
sound fundamentally, that it contained the germ of a good thing, but needed
working out. Associated with General Palmer was one Col. Josiah C. Reiff,
then Eastern bond agent for the Kansas Pacific Railroad. The Colonel was
always resourceful, and didn't fail in this case. He knew of a young fellow
who was doing some good work for Marshall Lefferts, and who it was said
was a genius at invention, and a very fiend for work. His name was Edison,
and he had a shop out at Newark, New Jersey. He came and was put in my
care for the purpose of a mutual exchange of ideas and for a report by me as
to his competency in the matter. This was my introduction to Edison. He
confirmed my views of the automatic system. He saw its possibilities, as
well as the chief obstacles to be overcome—viz., the sluggishness of the
wire, together with the need of mechanical betterment of the apparatus; and
he agreed to take the job on one condition—namely, that Johnson would
stay and help, as 'he was a man with ideas.' Mr. Johnson was accordingly

given three months' leave from Colorado railroad-building, and has never
seen Colorado since."
Applying himself to the difficulties with wonted energy, Edison devised
new apparatus, and solved the problem to such an extent that he and his
assistants succeeded in transmitting and recording one thousand words per
minute between New York and Washington, and thirty-five hundred words
per minute to Philadelphia. Ordinary manual transmission by key is not in
excess of forty to fifty words a minute. Stated very briefly, Edison's
principal contribution to the commercial development of the automatic was
based on the observation that in a line of considerable length electrical
impulses become enormously extended, or sluggish, due to a phenomenon
known as self-induction, which with ordinary Morse work is in a measure
corrected by condensers. But in the automatic the aim was to deal with
impulses following each other from twenty-five to one hundred times as
rapidly as in Morse lines, and to attempt to receive and record intelligibly
such a lightning-like succession of signals would have seemed impossible.
But Edison discovered that by utilizing a shunt around the receiving
instrument, with a soft iron core, the self-induction would produce a
momentary and instantaneous reversal of the current at the end of each
impulse, and thereby give an absolutely sharp definition to each signal. This
discovery did away entirely with sluggishness, and made it possible to
secure high speeds over lines of comparatively great lengths. But Edison's
work on the automatic did not stop with this basic suggestion, for he took
up and perfected the mechanical construction of the instruments, as well as
the perforators, and also suggested numerous electrosensitive chemicals for
the receivers, so that the automatic telegraph, almost entirely by reason of
his individual work, was placed on a plane of commercial practicability.
The long line of patents secured by him in this art is an interesting exhibit
of the development of a germ to a completed system, not, as is usually the
case, by numerous inventors working over considerable periods of time, but
by one man evolving the successive steps at a white heat of activity.
This system was put in commercial operation, but the company, now
encouraged, was quite willing to allow Edison to work out his idea of an
automatic that would print the message in bold Roman letters instead of in
dots and dashes; with consequent gain in speed in delivery of the message
after its receipt in the operating-room, it being obviously necessary in the
case of any message received in Morse characters to copy it in script before
seen Colorado since."

delivery to the recipient. A large shop was rented in Newark, equipped with
$25,000 worth of machinery, and Edison was given full charge. Here he
built their original type of apparatus, as improved, and also pushed his
experiments on the letter system so far that at a test, between New York and
Philadelphia, three thousand words were sent in one minute and recorded in
Roman type. Mr. D. N. Craig, one of the early organizers of the Associated
Press, became interested in this company, whose president was Mr. George
Harrington, formerly Assistant Secretary of the United States Treasury.
Mr. Craig brought with him at this time—the early seventies—from
Milwaukee a Mr. Sholes, who had a wooden model of a machine to which
had been given the then new and unfamiliar name of "typewriter." Craig
was interested in the machine, and put the model in Edison's hands to
perfect. "This typewriter proved a difficult thing," says Edison, "to make
commercial. The alignment of the letters was awful. One letter would be
one-sixteenth of an inch above the others; and all the letters wanted to
wander out of line. I worked on it till the machine gave fair results. [3]
Some were made and used in the office of the Automatic company. Craig
was very sanguine that some day all business letters would be written on a
typewriter. He died before that took place; but it gradually made its way.
The typewriter I got into commercial shape is now known as the
Remington. About this time I got an idea I could devise an apparatus by
which four messages could simultaneously be sent over a single wire
without interfering with each other. I now had five shops, and with
experimenting on this new scheme I was pretty busy; at least I did not have
ennui."
[Footnote 3: See illustration on opposite page, showing
reproduction of the work done with this machine.]
A very interesting picture of Mr. Edison at this time is furnished by Mr.
Patrick B. Delany, a well-known inventor in the field of automatic and
multiplex telegraphy, who at that time was a chief operator of the Franklin
Telegraph Company at Philadelphia. His remark about Edison that "his
ingenuity inspired confidence, and wavering financiers stiffened up when it
became known that he was to develop the automatic" is a noteworthy
evidence of the manner in which the young inventor had already gained a
firm footing. He continues: "Edward H. Johnson was brought on from the
Denver & Rio Grande Railway to assist in the practical introduction of
$25,000 worth of machinery, and Edison was given full charge. Here he

firm footing. He continues: "Edward H. Johnson was brought on from the
Denver & Rio Grande Railway to assist in the practical introduction of
Page 107
automatic telegraphy on a commercial basis, and about this time, in 1872, I
joined the enterprise. Fairly good results were obtained between New York
and Washington, and Edison, indifferent to theoretical difficulties, set out to
prove high speeds between New York and Charleston, South Carolina, the
compound wire being hitched up to one of the Southern & Atlantic wires
from Washington to Charleston for the purpose of experimentation. Johnson
and I went to the Charleston end to carry out Edison's plans, which were
rapidly unfolded by telegraph every night from a loft on lower Broadway,
New York. We could only get the wire after all business was cleared,
usually about midnight, and for months, in the quiet hours, that wire was
subjected to more electrical acrobatics than any other wire ever
experienced. When the experiments ended, Edison's system was put into
regular commercial operation between New York and Washington; and did
fine work. If the single wire had not broken about every other day, the
venture would have been a financial success; but moisture got in between
the copper ribbon and the steel core, setting up galvanic action which made
short work of the steel. The demonstration was, however, sufficiently
successful to impel Jay Gould to contract to pay about $4,000,000 in stock
for the patents. The contract was never completed so far as the $4,000,000
were concerned, but Gould made good use of it in getting control of the
Western Union."
One of the most important persons connected with the automatic
enterprise was Mr. George Harrington, to whom we have above referred,
and with whom Mr. Edison entered into close confidential relations, so that
the inventions made were held jointly, under a partnership deed covering
"any inventions or improvements that may be useful or desired in automatic
telegraphy." Mr. Harrington was assured at the outset by Edison that while
the Little perforator would give on the average only seven or eight words
per minute, which was not enough for commercial purposes, he could
devise one giving fifty or sixty words, and that while the Little solution for
the receiving tape cost $15 to $17 per gallon, he could furnish a ferric
solution costing only five or six cents per gallon. In every respect Edison
"made good," and in a short time the system was a success, "Mr. Little
having withdrawn his obsolete perforator, his ineffective resistance, his
costly chemical solution, to give place to Edison's perforator, Edison's
resistance and devices, and Edison's solution costing a few cents per gallon.
But," continues Mr. Harrington, in a memorable affidavit, "the inventive

But," continues Mr. Harrington, in a memorable affidavit, "the inventive
Page 108
efforts of Mr. Edison were not confined to automatic telegraphy, nor did
they cease with the opening of that line to Washington." They all led up to
the quadruplex.
Flattered by their success, Messrs. Harrington and Reiff, who owned with
Edison the foreign patents for the new automatic system, entered into an
arrangement with the British postal telegraph authorities for a trial of the
system in England, involving its probable adoption if successful. Edison
was sent to England to make the demonstration, in 1873, reporting there to
Col. George E. Gouraud, who had been an associate in the United States
Treasury with Mr. Harrington, and was now connected with the new
enterprise. With one small satchel of clothes, three large boxes of
instruments, and a bright fellow-telegrapher named Jack Wright, he took
voyage on the Jumping Java, as she was humorously known, of the Cunard
line. The voyage was rough and the little Java justified her reputation by
jumping all over the ocean. "At the table," says Edison, "there were never
more than ten or twelve people. I wondered at the time how it could pay to
run an ocean steamer with so few people; but when we got into calm water
and could see the green fields, I was astounded to see the number of people
who appeared. There were certainly two or three hundred. I learned
afterward that they were mostly going to the Vienna Exposition. Only two
days could I get on deck, and on one of these a gentleman had a bad scalp
wound from being thrown against the iron wall of a small smoking-room
erected over a freight hatch."
Arrived in London, Edison set up his apparatus at the Telegraph Street
headquarters, and sent his companion to Liverpool with the instruments for
that end. The condition of the test was that he was to send from Liverpool
and receive in London, and to record at the rate of one thousand words per
minute, five hundred words to be sent every half hour for six hours. Edison
was given a wire and batteries to operate with, but a preliminary test soon
showed that he was going to fail. Both wire and batteries were poor, and
one of the men detailed by the authorities to watch the test remarked
quietly, in a friendly way: "You are not going to have much show. They are
going to give you an old Bridgewater Canal wire that is so poor we don't
work it, and a lot of 'sand batteries' at Liverpool." [4] The situation was
rather depressing to the young American thus encountering, for the first
time, the stolid conservatism and opposition to change that characterizes so
much of official life and methods in Europe. "I thanked him," says Edison,
they cease with the opening of that line to Washington." They all led up to

much of official life and methods in Europe. "I thanked him," says Edison,
Page 109
"and hoped to reciprocate somehow. I knew I was in a hole. I had been
staying at a little hotel in Covent Garden called the Hummums! and got
nothing but roast beef and flounders, and my imagination was getting into a
coma. What I needed was pastry. That night I found a French pastry shop in
High Holborn Street and filled up. My imagination got all right. Early in the
morning I saw Gouraud, stated my case, and asked if he would stand for the
purchase of a powerful battery to send to Liverpool. He said 'Yes.' I went
immediately to Apps on the Strand and asked if he had a powerful battery.
He said he hadn't; that all that he had was Tyndall's Royal Institution
battery, which he supposed would not serve. I saw it—one hundred cells—
and getting the price—one hundred guineas—hurried to Gouraud. He said
'Go ahead.' I telegraphed to the man in Liverpool. He came on, got the
battery to Liverpool, set up and ready, just two hours before the test
commenced. One of the principal things that made the system a success was
that the line was put to earth at the sending end through a magnet, and the
extra current from this, passed to the line, served to sharpen the recording
waves. This new battery was strong enough to pass a powerful current
through the magnet without materially diminishing the strength of the line
current."
[Footnote 4: The sand battery is now obsolete. In this type,
the cell containing the elements was filled with sand, which
was kept moist with an electrolyte.]
The test under these more favorable circumstances was a success. "The
record was as perfect as copper plate, and not a single remark was made in
the 'time lost' column." Edison was now asked if he thought he could get a
greater speed through submarine cables with this system than with the
regular methods, and replied that he would like a chance to try it. For this
purpose, twenty-two hundred miles of Brazilian cable then stored under
water in tanks at the Greenwich works of the Telegraph Construction &
Maintenance Company, near London, was placed at his disposal from 8
P.M. until 6 A.M. "This just suited me, as I preferred night-work. I got my
apparatus down and set up, and then to get a preliminary idea of what the
distortion of the signal would be, I sent a single dot, which should have
been recorded upon my automatic paper by a mark about one-thirty-second
of an inch long. Instead of that it was twenty-seven feet long! If I ever had
any conceit, it vanished from my boots up. I worked on this cable more than
two weeks, and the best I could do was two words per minute, which was

P.M. until 6 A.M. "This just suited me, as I preferred night-work. I got my
apparatus down and set up, and then to get a preliminary idea of what the
distortion of the signal would be, I sent a single dot, which should have
been recorded upon my automatic paper by a mark about one-thirty-second
of an inch long. Instead of that it was twenty-seven feet long! If I ever had
any conceit, it vanished from my boots up. I worked on this cable more than
two weeks, and the best I could do was two words per minute, which was
Page 110
only one-seventh of what the guaranteed speed of the cable should be when
laid. What I did not know at the time was that a coiled cable, owing to
induction, was infinitely worse than when laid out straight, and that my
speed was as good as, if not better than, with the regular system; but no one
told me this." While he was engaged on these tests Colonel Gouraud came
down one night to visit him at the lonely works, spent a vigil with him, and
toward morning wanted coffee. There was only one little inn near by,
frequented by longshoremen and employees from the soap-works and
cement-factories—a rough lot—and there at daybreak they went as soon as
the other customers had left for work. "The place had a bar and six bare
tables, and was simply infested with roaches. The only things that I ever
could get were coffee made from burnt bread, with brown molasses-cake. I
ordered these for Gouraud. The taste of the coffee, the insects, etc., were too
much. He fainted. I gave him a big dose of gin, and this revived him. He
went back to the works and waited until six when the day men came, and
telegraphed for a carriage. He lost all interest in the experiments after that,
and I was ordered back to America." Edison states, however, that the
automatic was finally adopted in England and used for many years; indeed,
is still in use there. But they took whatever was needed from his system,
and he "has never had a cent from them."
Arduous work was at once resumed at home on duplex and quadruplex
telegraphy, just as though there had been no intermission or discouragement
over dots twenty-seven feet long. A clue to his activity is furnished in the
fact that in 1872 he had applied for thirty-eight patents in the class of
telegraphy, and twenty-five in 1873; several of these being for duplex
methods, on which he had experimented. The earlier apparatus had been
built several years prior to this, as shown by a curious little item of news
that appeared in the Telegrapher of January 30, 1869: "T. A. Edison has
resigned his situation in the Western Union office, Boston, and will devote
his time to bringing out his inventions." Oh, the supreme, splendid
confidence of youth! Six months later, as we have seen, he had already
made his mark, and the same journal, in October, 1869, could say: "Mr.
Edison is a young man of the highest order of mechanical talent, combined
with good scientific electrical knowledge and experience. He has already
invented and patented a number of valuable and useful inventions, among
which may be mentioned the best instrument for double transmission yet
brought out." Not bad for a novice of twenty-two. It is natural, therefore,
laid. What I did not know at the time was that a coiled cable, owing to

Page 111
after his intervening work on indicators, stock tickers, automatic telegraphs,
and typewriters, to find him harking back to duplex telegraphy, if, indeed,
he can be said to have dropped it in the interval. It has always been one of
the characteristic features of Edison's method of inventing that work in
several lines has gone forward at the same time. No one line of
investigation has ever been enough to occupy his thoughts fully; or to
express it otherwise, he has found rest in turning from one field of work to
another, having absolutely no recreations or hobbies, and not needing them.
It may also be said that, once entering it, Mr. Edison has never abandoned
any field of work. He may change the line of attack; he may drop the
subject for a time; but sooner or later the note-books or the Patent Office
will bear testimony to the reminiscent outcropping of latent thought on the
matter. His attention has shifted chronologically, and by process of
evolution, from one problem to another, and some results are found to be
final; but the interest of the man in the thing never dies out. No one sees
more vividly than he the fact that in the interplay of the arts one industry
shapes and helps another, and that no invention lives to itself alone.
The path to the quadruplex lay through work on the duplex, which,
suggested first by Moses G. Farmer in 1852, had been elaborated by many
ingenious inventors, notably in this country by Stearns, before Edison once
again applied his mind to it. The different methods of such multiple
transmission—namely, the simultaneous dispatch of the two
communications in opposite directions over the same wire, or the dispatch
of both at once in the same direction—gave plenty of play to ingenuity.
Prescott's Elements of the Electric Telegraph, a standard work in its day,
described "a method of simultaneous transmission invented by T. A. Edison,
of New Jersey, in 1873," and says of it: "Its peculiarity consists in the fact
that the signals are transmitted in one direction by reversing the polarity of
a constant current, and in the opposite direction by increasing or decreasing
the strength of the same current." Herein lay the germ of the Edison
quadruplex. It is also noted that "In 1874 Edison invented a method of
simultaneous transmission by induced currents, which has given very
satisfactory results in experimental trials." Interest in the duplex as a field
of invention dwindled, however, as the quadruplex loomed up, for while the
one doubled the capacity of a circuit, the latter created three "phantom
wires," and thus quadruplexed the working capacity of any line to which it
was applied. As will have been gathered from the above, the principle
and typewriters, to find him harking back to duplex telegraphy, if, indeed,
he can be said to have dropped it in the interval. It has always been one of

one doubled the capacity of a circuit, the latter created three "phantom
wires," and thus quadruplexed the working capacity of any line to which it
was applied. As will have been gathered from the above, the principle
Page 112
embodied in the quadruplex is that of working over the line with two
currents from each end that differ from each other in strength or nature, so
that they will affect only instruments adapted to respond to just such
currents and no others; and by so arranging the receiving apparatus as not to
be affected by the currents transmitted from its own end of the line. Thus by
combining instruments that respond only to variation in the strength of
current from the distant station, with instruments that respond only to the
change in the direction of current from the distant station, and by grouping
a pair of these at each end of the line, the quadruplex is the result. Four
sending and four receiving operators are kept busy at each end, or eight in
all. Aside from other material advantages, it is estimated that at least from
$15,000,000 to $20,000,000 has been saved by the Edison quadruplex
merely in the cost of line construction in America.
The quadruplex has not as a rule the same working efficiency that four
separate wires have. This is due to the fact that when one of the receiving
operators is compelled to "break" the sending operator for any reason, the
"break" causes the interruption of the work of eight operators, instead of
two, as would be the case on a single wire. The working efficiency of the
quadruplex, therefore, with the apparatus in good working condition,
depends entirely upon the skill of the operators employed to operate it. But
this does not reflect upon or diminish the ingenuity required for its
invention. Speaking of the problem involved, Edison said some years later
to Mr. Upton, his mathematical assistant, that "he always considered he was
only working from one room to another. Thus he was not confused by the
amount of wire and the thought of distance."
The immense difficulties of reducing such a system to practice may be
readily conceived, especially when it is remembered that the "line" itself,
running across hundreds of miles of country, is subject to all manner of
atmospheric conditions, and varies from moment to moment in its ability to
carry current, and also when it is borne in mind that the quadruplex requires
at each end of the line a so-called "artificial line," which must have the
exact resistance of the working line and must be varied with the variations
in resistance of the working line. At this juncture other schemes were
fermenting in his brain; but the quadruplex engrossed him. "This problem
was of most difficult and complicated kind, and I bent all my energies
toward its solution. It required a peculiar effort of the mind, such as the
imagining of eight different things moving simultaneously on a mental
currents from each end that differ from each other in strength or nature, so
that they will affect only instruments adapted to respond to just such
currents and no others; and by so arranging the receiving apparatus as not to
be affected by the currents transmitted from its own end of the line. Thus by
combining instruments that respond only to variation in the strength of

to be wondered at that when notified he would have to pay 12 1/2 per cent.

own name when asked for it suddenly at the City Hall, lost his place in the
line, and, the fatal hour striking, had to pay the surcharge after all!
So important an invention as the quadruplex could not long go begging,
but there were many difficulties connected with its introduction, some of
which are best described in Mr. Edison's own words: "Around 1873 the
owners of the Automatic Telegraph Company commenced negotiations with
Jay Gould for the purchase of the wires between New York and
Washington, and the patents for the system, then in successful operation.
Jay Gould at that time controlled the Atlantic & Pacific Telegraph
Company, and was competing with the Western Union and endeavoring to
depress Western Union stock on the Exchange. About this time I invented
the quadruplex. I wanted to interest the Western Union Telegraph Company
in it, with a view of selling it, but was unsuccessful until I made an
arrangement with the chief electrician of the company, so that he could be
known as a joint inventor and receive a portion of the money. At that time I
was very short of money, and needed it more than glory. This electrician
appeared to want glory more than money, so it was an easy trade. I brought
my apparatus over and was given a separate room with a marble-tiled floor,
which, by-the-way, was a very hard kind of floor to sleep on, and started in
putting on the finishing touches.
"After two months of very hard work, I got a detail at regular times of
eight operators, and we got it working nicely from one room to another over
a wire which ran to Albany and back. Under certain conditions of weather,
one side of the quadruplex would work very shakily, and I had not
succeeded in ascertaining the cause of the trouble. On a certain day, when
there was a board meeting of the company, I was to make an exhibition test.
The day arrived. I had picked the best operators in New York, and they were
familiar with the apparatus. I arranged that if a storm occurred, and the bad
side got shaky, they should do the best they could and draw freely on their
imaginations. They were sending old messages. About 1, o'clock everything
went wrong, as there was a storm somewhere near Albany, and the bad side
got shaky. Mr. Orton, the president, and Wm. H. Vanderbilt and the other
directors came in. I had my heart trying to climb up around my oesophagus.
I was paying a sheriff five dollars a day to withhold judgment which had
to be wondered at that when notified he would have to pay 12 1/2 per cent.

I was paying a sheriff five dollars a day to withhold judgment which had
Page 114
been entered against me in a case which I had paid no attention to; and if
the quadruplex had not worked before the president, I knew I was to have
trouble and might lose my machinery. The New York Times came out next
day with a full account. I was given $5000 as part payment for the
invention, which made me easy, and I expected the whole thing would be
closed up. But Mr. Orton went on an extended tour just about that time. I
had paid for all the experiments on the quadruplex and exhausted the
money, and I was again in straits. In the mean time I had introduced the
apparatus on the lines of the company, where it was very successful.
"At that time the general superintendent of the Western Union was Gen.
T. T. Eckert (who had been Assistant Secretary of War with Stanton). Eckert
was secretly negotiating with Gould to leave the Western Union and take
charge of the Atlantic & Pacific—Gould's company. One day Eckert called
me into his office and made inquiries about money matters. I told him Mr.
Orton had gone off and left me without means, and I was in straits. He told
me I would never get another cent, but that he knew a man who would buy
it. I told him of my arrangement with the electrician, and said I could not
sell it as a whole to anybody; but if I got enough for it, I would sell all my
interest in any SHARE I might have. He seemed to think his party would
agree to this. I had a set of quadruplex over in my shop, 10 and 12 Ward
Street, Newark, and he arranged to bring him over next evening to see the
apparatus. So the next morning Eckert came over with Jay Gould and
introduced him to me. This was the first time I had ever seen him. I
exhibited and explained the apparatus, and they departed. The next day
Eckert sent for me, and I was taken up to Gould's house, which was near the
Windsor Hotel, Fifth Avenue. In the basement he had an office. It was in the
evening, and we went in by the servants' entrance, as Eckert probably
feared that he was watched. Gould started in at once and asked me how
much I wanted. I said: 'Make me an offer.' Then he said: 'I will give you
$30,000.' I said: 'I will sell any interest I may have for that money,' which
was something more than I thought I could get. The next morning I went
with Gould to the office of his lawyers, Sherman & Sterling, and received a
check for $30,000, with a remark by Gould that I had got the steamboat
Plymouth Rock, as he had sold her for $30,000 and had just received the
check. There was a big fight on between Gould's company and the Western
Union, and this caused more litigation. The electrician, on account of the
testimony involved, lost his glory. The judge never decided the case, but
the quadruplex had not worked before the president, I knew I was to have
trouble and might lose my machinery. The New York Times came out next
day with a full account. I was given $5000 as part payment for the

testimony involved, lost his glory. The judge never decided the case, but
Page 115
went crazy a few months afterward." It was obviously a characteristically
shrewd move on the part of Mr. Gould to secure an interest in the
quadruplex, as a factor in his campaign against the Western Union, and as a
decisive step toward his control of that system, by the subsequent merger
that included not only the Atlantic & Pacific Telegraph Company, but the
American Union Telegraph Company.
Nor was Mr. Gould less appreciative of the value of Edison's automatic
system. Referring to matters that will be taken up later in the narrative,
Edison says: "After this Gould wanted me to help install the automatic
system in the Atlantic & Pacific company, of which General Eckert had
been elected president, the company having bought the Automatic
Telegraph Company. I did a lot of work for this company making automatic
apparatus in my shop at Newark. About this time I invented a district
messenger call-box system, and organized a company called the Domestic
Telegraph Company, and started in to install the system in New York. I had
great difficulty in getting subscribers, having tried several canvassers, who,
one after the other, failed to get subscribers. When I was about to give it up,
a test operator named Brown, who was on the Automatic Telegraph wire
between New York and Washington, which passed through my Newark
shop, asked permission to let him try and see if he couldn't get subscribers. I
had very little faith in his ability to get any, but I thought I would give him a
chance, as he felt certain of his ability to succeed. He started in, and the
results were surprising. Within a month he had procured two hundred
subscribers, and the company was a success. I have never quite understood
why six men should fail absolutely, while the seventh man should succeed.
Perhaps hypnotism would account for it. This company was sold out to the
Atlantic & Pacific company." As far back as 1872, Edison had applied for a
patent on district messenger signal boxes, but it was not issued until
January, 1874, another patent being granted in September of the same year.
In this field of telegraph application, as in others, Edison was a very early
comer, his only predecessor being the fertile and ingenious Callahan, of
stock-ticker fame. The first president of the Gold & Stock Telegraph
Company, Elisha W. Andrews, had resigned in 1870 in order to go to
England to introduce the stock ticker in London. He lived in Englewood,
New Jersey, and the very night he had packed his trunk the house was
burglarized. Calling on his nearest friend the next morning for even a pair
of suspenders, Mr. Andrews was met with regrets of inability, because the
shrewd move on the part of Mr. Gould to secure an interest in the
quadruplex, as a factor in his campaign against the Western Union, and as a
decisive step toward his control of that system, by the subsequent merger
that included not only the Atlantic & Pacific Telegraph Company, but the
American Union Telegraph Company.

Page 116
burglars had also been there. A third and fourth friend in the vicinity was
appealed to with the same disheartening reply of a story of wholesale
spoliation. Mr. Callahan began immediately to devise a system of protection
for Englewood; but at that juncture a servant-girl who had been for many
years with a family on the Heights in Brooklyn went mad suddenly and held
an aged widow and her daughter as helpless prisoners for twenty-four hours
without food or water. This incident led to an extension of the protective
idea, and very soon a system was installed in Brooklyn with one hundred
subscribers. Out of this grew in turn the district messenger system, for it
was just as easy to call a messenger as to sound a fire-alarm or summon the
police. To-day no large city in America is without a service of this
character, but its function was sharply limited by the introduction of the
telephone.
Returning to the automatic telegraph it is interesting to note that so long
as Edison was associated with it as a supervising providence it did splendid
work, which renders the later neglect of automatic or "rapid telegraphy" the
more remarkable. Reid's standard Telegraph in America bears astonishing
testimony on this point in 1880, as follows: "The Atlantic & Pacific
Telegraph Company had twenty-two automatic stations. These included the
chief cities on the seaboard, Buffalo, Chicago, and Omaha. The through
business during nearly two years was largely transmitted in this way.
Between New York and Boston two thousand words a minute have been
sent. The perforated paper was prepared at the rate of twenty words per
minute. Whatever its demerits this system enabled the Atlantic & Pacific
company to handle a much larger business during 1875 and 1876 than it
could otherwise have done with its limited number of wires in their then
condition." Mr. Reid also notes as a very thorough test of the perfect
practicability of the system, that it handled the President's message,
December 3, 1876, of 12,600 words with complete success. This long
message was filed at Washington at 1.05 and delivered in New York at 2.07.
The first 9000 words were transmitted in forty-five minutes. The perforated
strips were prepared in thirty minutes by ten persons, and duplicated by
nine copyists. But to-day, nearly thirty-five years later, telegraphy in
America is still practically on a basis of hand transmission!
Of this period and his association with Jay Gould, some very interesting
glimpses are given by Edison. "While engaged in putting in the automatic
system, I saw a great deal of Gould, and frequently went uptown to his
appealed to with the same disheartening reply of a story of wholesale
spoliation. Mr. Callahan began immediately to devise a system of protection
for Englewood; but at that juncture a servant-girl who had been for many
years with a family on the Heights in Brooklyn went mad suddenly and held
an aged widow and her daughter as helpless prisoners for twenty-four hours
without food or water. This incident led to an extension of the protective
idea, and very soon a system was installed in Brooklyn with one hundred
subscribers. Out of this grew in turn the district messenger system, for it
was just as easy to call a messenger as to sound a fire-alarm or summon the
police. To-day no large city in America is without a service of this
character, but its function was sharply limited by the introduction of the
telephone.
Returning to the automatic telegraph it is interesting to note that so long
as Edison was associated with it as a supervising providence it did splendid
work, which renders the later neglect of automatic or "rapid telegraphy" the
more remarkable. Reid's standard Telegraph in America bears astonishing
testimony on this point in 1880, as follows: "The Atlantic & Pacific
Telegraph Company had twenty-two automatic stations. These included the
chief cities on the seaboard, Buffalo, Chicago, and Omaha. The through
business during nearly two years was largely transmitted in this way.

glimpses are given by Edison. "While engaged in putting in the automatic

Page 117
office to give information. Gould had no sense of humor. I tried several
times to get off what seemed to me a funny story, but he failed to see any
humor in them. I was very fond of stories, and had a choice lot, always kept
fresh, with which I could usually throw a man into convulsions. One
afternoon Gould started in to explain the great future of the Union Pacific
Railroad, which he then controlled. He got a map, and had an immense
amount of statistics. He kept at it for over four hours, and got very
enthusiastic. Why he should explain to me, a mere inventor, with no capital
or standing, I couldn't make out. He had a peculiar eye, and I made up my
mind that there was a strain of insanity somewhere. This idea was
strengthened shortly afterward when the Western Union raised the monthly
rental of the stock tickers. Gould had one in his house office, which he
watched constantly. This he had removed, to his great inconvenience,
because the price had been advanced a few dollars! He railed over it. This
struck me as abnormal. I think Gould's success was due to abnormal
development. He certainly had one trait that all men must have who want to
succeed. He collected every kind of information and statistics about his
schemes, and had all the data. His connection with men prominent in
official life, of which I was aware, was surprising to me. His conscience
seemed to be atrophied, but that may be due to the fact that he was
contending with men who never had any to be atrophied. He worked
incessantly until 12 or 1 o'clock at night. He took no pride in building up an
enterprise. He was after money, and money only. Whether the company was
a success or a failure mattered not to him. After he had hammered the
Western Union through his opposition company and had tired out Mr.
Vanderbilt, the latter retired from control, and Gould went in and
consolidated his company and controlled the Western Union. He then
repudiated the contract with the Automatic Telegraph people, and they
never received a cent for their wires or patents, and I lost three years of very
hard labor. But I never had any grudge against him, because he was so able
in his line, and as long as my part was successful the money with me was a
secondary consideration. When Gould got the Western Union I knew no
further progress in telegraphy was possible, and I went into other lines."
The truth is that General Eckert was a conservative—even a reactionary—
and being prejudiced like many other American telegraph managers against
"machine telegraphy," threw out all such improvements.

The course of electrical history has been variegated by some very
remarkable litigation; but none was ever more extraordinary than that
referred to here as arising from the transfer of the Automatic Telegraph
Company to Mr. Jay Gould and the Atlantic & Pacific Telegraph Company.
The terms accepted by Colonel Reiff from Mr. Gould, on December 30,
1874, provided that the purchasing telegraph company should increase its
capital to $15,000,000, of which the Automatic interests were to receive
$4,000,000 for their patents, contracts, etc. The stock was then selling at
about 25, and in the later consolidation with the Western Union "went in" at
about 60; so that the real purchase price was not less than $1,000,000 in
cash. There was a private arrangement in writing with Mr. Gould that he
was to receive one-tenth of the "result" to the Automatic group, and a tenth
of the further results secured at home and abroad. Mr. Gould personally
bought up and gave money and bonds for one or two individual interests on
the above basis, including that of Harrington, who in his representative
capacity executed assignments to Mr. Gould. But payments were then
stopped, and the other owners were left without any compensation,
although all that belonged to them in the shape of property and patents was
taken over bodily into Atlantic & Pacific hands, and never again left them.
Attempts at settlement were made in their behalf, and dragged wearily, due
apparently to the fact that the plans were blocked by General Eckert, who
had in some manner taken offence at a transaction effected without his
active participation in all the details. Edison, who became under the
agreement the electrician of the Atlantic & Pacific Telegraph Company, has
testified to the unfriendly attitude assumed toward him by General Eckert,
as president. In a graphic letter from Menlo Park to Mr. Gould, dated
February 2, 1877, Edison makes a most vigorous and impassioned
complaint of his treatment, "which, acting cumulatively, was a long,
unbroken disappointment to me"; and he reminds Mr. Gould of promises
made to him the day the transfer had been effected of Edison's interest in
the quadruplex. The situation was galling to the busy, high-spirited young
inventor, who, moreover, "had to live"; and it led to his resumption of work
for the Western Union Telegraph Company, which was only too glad to get
him back. Meantime, the saddened and perplexed Automatic group was left
unpaid, and it was not until 1906, on a bill filed nearly thirty years before,
that Judge Hazel, in the United States Circuit Court for the Southern
District of New York, found strongly in favor of the claimants and ordered
remarkable litigation; but none was ever more extraordinary than that
referred to here as arising from the transfer of the Automatic Telegraph

that Judge Hazel, in the United States Circuit Court for the Southern
District of New York, found strongly in favor of the claimants and ordered
Page 119
an accounting. The court held that there had been a most wrongful
appropriation of the patents, including alike those relating to the automatic,
the duplex, and the quadruplex, all being included in the general
arrangement under which Mr. Gould had held put his tempting bait of
$4,000,000. In the end, however, the complainant had nothing to show for
all his struggle, as the master who made the accounting set the damages at
one dollar!
Aside from the great value of the quadruplex, saving millions of dollars,
for a share in which Edison received $30,000, the automatic itself is
described as of considerable utility by Sir William Thomson in his juror
report at the Centennial Exposition of 1876, recommending it for award.
This leading physicist of his age, afterward Lord Kelvin, was an adept in
telegraphy, having made the ocean cable talk, and he saw in Edison's
"American Automatic," as exhibited by the Atlantic & Pacific company, a
most meritorious and useful system. With the aid of Mr. E. H. Johnson he
made exhaustive tests, carrying away with him to Glasgow University the
surprising records that he obtained. His official report closes thus: "The
electromagnetic shunt with soft iron core, invented by Mr. Edison, utilizing
Professor Henry's discovery of electromagnetic induction in a single circuit
to produce a momentary reversal of the line current at the instant when the
battery is thrown off and so cut off the chemical marks sharply at the proper
instant, is the electrical secret of the great speed he has achieved. The main
peculiarities of Mr. Edison's automatic telegraph shortly stated in
conclusion are: (1) the perforator; (2) the contact-maker; (3) the
electromagnetic shunt; and (4) the ferric cyanide of iron solution. It
deserves award as a very important step in land telegraphy." The attitude
thus disclosed toward Mr. Edison's work was never changed, except that
admiration grew as fresh inventions were brought forward. To the day of his
death Lord Kelvin remained on terms of warmest friendship with his
American co-laborer, with whose genius he thus first became acquainted at
Philadelphia in the environment of Franklin.
It is difficult to give any complete idea of the activity maintained at the
Newark shops during these anxious, harassed years, but the statement that
at one time no fewer than forty-five different inventions were being worked
upon, will furnish some notion of the incandescent activity of the inventor
and his assistants. The hours were literally endless; and upon one occasion,
when the order was in hand for a large quantity of stock tickers, Edison

when the order was in hand for a large quantity of stock tickers, Edison
Page 120
locked his men in until the job had been finished of making the machine
perfect, and "all the bugs taken out," which meant sixty hours of
unintermitted struggle with the difficulties. Nor were the problems and
inventions all connected with telegraphy. On the contrary, Edison's mind
welcomed almost any new suggestion as a relief from the regular work in
hand. Thus: "Toward the latter part of 1875, in the Newark shop, I invented
a device for multiplying copies of letters, which I sold to Mr. A. B. Dick, of
Chicago, and in the years since it has been universally introduced
throughout the world. It is called the 'Mimeograph.' I also invented devices
for and introduced paraffin paper, now used universally for wrapping up
candy, etc." The mimeograph employs a pointed stylus, used as in writing
with a lead-pencil, which is moved over a kind of tough prepared paper
placed on a finely grooved steel plate. The writing is thus traced by means
of a series of minute perforations in the sheet, from which, as a stencil,
hundreds of copies can be made. Such stencils can be prepared on
typewriters. Edison elaborated this principle in two other forms—one
pneumatic and one electric—the latter being in essence a reciprocating
motor. Inside the barrel of the electric pen a little plunger, carrying the
stylus, travels to and fro at a very high rate of speed, due to the attraction
and repulsion of the solenoid coils of wire surrounding it; and as the hand
of the writer guides it the pen thus makes its record in a series of very
minute perforations in the paper. The current from a small battery suffices
to energize the pen, and with the stencil thus made hundreds of copies of
the document can be furnished. As a matter of fact, as many as three
thousand copies have been made from a single mimeographic stencil of this

CHAPTER IX
THE TELEPHONE, MOTOGRAPH, AND MICROPHONE
A VERY great invention has its own dramatic history. Episodes full of
human interest attend its development. The periods of weary struggle, the
daring adventure along unknown paths, the clash of rival claimants, are
closely similar to those which mark the revelation and subjugation of a new
continent. At the close of the epoch of discovery it is seen that mankind as a
whole has made one more great advance; but in the earlier stages one
watched chiefly the confused vicissitudes of fortune of the individual
pioneers. The great modern art of telephony has had thus in its beginnings,
its evolution, and its present status as a universal medium of intercourse, all
the elements of surprise, mystery, swift creation of wealth, tragic interludes,
and colossal battle that can appeal to the imagination and hold public
attention. And in this new electrical industry, in laying its essential
foundations, Edison has again been one of the dominant figures.
As far back as 1837, the American, Page, discovered the curious fact that
an iron bar, when magnetized and demagnetized at short intervals of time,
emitted sounds due to the molecular disturbances in the mass. Philipp Reis,
a simple professor in Germany, utilized this principle in the construction of
apparatus for the transmission of sound; but in the grasp of the idea he was
preceded by Charles Bourseul, a young French soldier in Algeria, who in
1854, under the title of "Electrical Telephony," in a Parisian illustrated
paper, gave a brief and lucid description as follows:
"We know that sounds are made by vibrations, and are made sensible to
the ear by the same vibrations, which are reproduced by the intervening
medium. But the intensity of the vibrations diminishes very rapidly with the
distance; so that even with the aid of speaking-tubes and trumpets it is
impossible to exceed somewhat narrow limits. Suppose a man speaks near a
movable disk sufficiently flexible to lose none of the vibrations of the
voice; that this disk alternately makes and breaks the connection with a
battery; you may have at a distance another disk which will simultaneously
execute the same vibrations.... Any one who is not deaf and dumb may use

Page 122
this mode of transmission, which would require no apparatus except an
electric battery, two vibrating disks, and a wire."
This would serve admirably for a portrayal of the Bell telephone, except
that it mentions distinctly the use of the make-and-break method (i. e.,
where the circuit is necessarily opened and closed as in telegraphy,
although, of course, at an enormously higher rate), which has never proved
practical.
So far as is known Bourseul was not practical enough to try his own
suggestion, and never made a telephone. About 1860, Reis built several
forms of electrical telephonic apparatus, all imitating in some degree the
human ear, with its auditory tube, tympanum, etc., and examples of the
apparatus were exhibited in public not only in Germany, but in England.
There is a variety of testimony to the effect that not only musical sounds,
but stray words and phrases, were actually transmitted with mediocre,
casual success. It was impossible, however, to maintain the devices in
adjustment for more than a few seconds, since the invention depended upon
the make-and-break principle, the circuit being made and broken every time
an impulse-creating sound went through it, causing the movement of the
diaphragm on which the sound-waves impinged. Reis himself does not
appear to have been sufficiently interested in the marvellous possibilities of
the idea to follow it up—remarking to the man who bought his telephonic
instruments and tools that he had shown the world the way. In reality it was
not the way, although a monument erected to his memory at Frankfort styles
him the inventor of the telephone. As one of the American judges said, in
deciding an early litigation over the invention of the telephone, a hundred
years of Reis would not have given the world the telephonic art for public
use. Many others after Reis tried to devise practical make-and-break
telephones, and all failed; although their success would have rendered them
very valuable as a means of fighting the Bell patent. But the method was a
good starting-point, even if it did not indicate the real path. If Reis had been
willing to experiment with his apparatus so that it did not make-and-break,
he would probably have been the true father of the telephone, besides
giving it the name by which it is known. It was not necessary to slam the
gate open and shut. All that was required was to keep the gate closed, and
rattle the latch softly. Incidentally it may be noted that Edison in
experimenting with the Reis transmitter recognized at once the defect
caused by the make-and-break action, and sought to keep the gap closed by
electric battery, two vibrating disks, and a wire."

the use, first, of one drop of water, and later of several drops. But the water
decomposed, and the incurable defect was still there.
The Reis telephone was brought to America by Dr. P. H. Van der Weyde,
a well-known physicist in his day, and was exhibited by him before a
technical audience at Cooper Union, New York, in 1868, and described
shortly after in the technical press. The apparatus attracted attention, and a
set was secured by Prof. Joseph Henry for the Smithsonian Institution.
There the famous philosopher showed and explained it to Alexander
Graham Bell, when that young and persevering Scotch genius went to get
help and data as to harmonic telegraphy, upon which he was working, and
as to transmitting vocal sounds. Bell took up immediately and energetically
the idea that his two predecessors had dropped—and reached the goal. In
1875 Bell, who as a student and teacher of vocal physiology had unusual
qualifications for determining feasible methods of speech transmission,
constructed his first pair of magneto telephones for such a purpose. In
February of 1876 his first telephone patent was applied for, and in March it
was issued. The first published account of the modern speaking telephone
was a paper read by Bell before the American Academy of Arts and
Sciences in Boston in May of that year; while at the Centennial Exposition
at Philadelphia the public first gained any familiarity with it. It was greeted
at once with scientific acclaim and enthusiasm as a distinctly new and great
invention, although at first it was regarded more as a scientific toy than as a
commercially valuable device.
By an extraordinary coincidence, the very day that Bell's application for a
patent went into the United States Patent Office, a caveat was filed there by
Elisha Gray, of Chicago, covering the specific idea of transmitting speech
and reproducing it in a telegraphic circuit "through an instrument capable of
vibrating responsively to all the tones of the human voice, and by which
they are rendered audible." Out of this incident arose a struggle and a
controversy whose echoes are yet heard as to the legal and moral rights of
the two inventors, the assertion even being made that one of the most
important claims of Gray, that on a liquid battery transmitter, was
surreptitiously "lifted" into the Bell application, then covering only the
magneto telephone. It was also asserted that the filing of the Gray caveat
antedated by a few hours the filing of the Bell application. All such issues
when brought to the American courts were brushed aside, the Bell patent
being broadly maintained in all its remarkable breadth and fullness,
decomposed, and the incurable defect was still there.
The Reis telephone was brought to America by Dr. P. H. Van der Weyde,
a well-known physicist in his day, and was exhibited by him before a
technical audience at Cooper Union, New York, in 1868, and described
shortly after in the technical press. The apparatus attracted attention, and a
set was secured by Prof. Joseph Henry for the Smithsonian Institution.
There the famous philosopher showed and explained it to Alexander
Graham Bell, when that young and persevering Scotch genius went to get
help and data as to harmonic telegraphy, upon which he was working, and
as to transmitting vocal sounds. Bell took up immediately and energetically
the idea that his two predecessors had dropped—and reached the goal. In
1875 Bell, who as a student and teacher of vocal physiology had unusual
qualifications for determining feasible methods of speech transmission,
constructed his first pair of magneto telephones for such a purpose. In
February of 1876 his first telephone patent was applied for, and in March it
was issued. The first published account of the modern speaking telephone
was a paper read by Bell before the American Academy of Arts and
Sciences in Boston in May of that year; while at the Centennial Exposition
at Philadelphia the public first gained any familiarity with it. It was greeted
at once with scientific acclaim and enthusiasm as a distinctly new and great
invention, although at first it was regarded more as a scientific toy than as a
commercially valuable device.
By an extraordinary coincidence, the very day that Bell's application for a
patent went into the United States Patent Office, a caveat was filed there by
Elisha Gray, of Chicago, covering the specific idea of transmitting speech
and reproducing it in a telegraphic circuit "through an instrument capable of
vibrating responsively to all the tones of the human voice, and by which
they are rendered audible." Out of this incident arose a struggle and a
controversy whose echoes are yet heard as to the legal and moral rights of
the two inventors, the assertion even being made that one of the most
important claims of Gray, that on a liquid battery transmitter, was
surreptitiously "lifted" into the Bell application, then covering only the
magneto telephone. It was also asserted that the filing of the Gray caveat
antedated by a few hours the filing of the Bell application. All such issues
when brought to the American courts were brushed aside, the Bell patent
being broadly maintained in all its remarkable breadth and fullness,
Page 124
embracing an entire art; but Gray was embittered and chagrined, and to the
last expressed his belief that the honor and glory should have been his. The
path of Gray to the telephone was a natural one. A Quaker carpenter who
studied five years at Oberlin College, he took up electrical invention, and
brought out many ingenious devices in rapid succession in the telegraphic
field, including the now universal needle annunciator for hotels, etc., the
useful telautograph, automatic self-adjusting relays, private-line printers—
leading up to his famous "harmonic" system. This was based upon the
principle that a sound produced in the presence of a reed or tuning-fork
responding to the sound, and acting as the armature of a magnet in a closed
circuit, would, by induction, set up electric impulses in the circuit and cause
a distant magnet having a similarly tuned armature to produce the same
tone or note. He also found that over the same wire at the same time another
series of impulses corresponding to another note could be sent through the
agency of a second set of magnets without in any way interfering with the
first series of impulses. Building the principle into apparatus, with a
keyboard and vibrating "reeds" before his magnets, Doctor Gray was able
not only to transmit music by his harmonic telegraph, but went so far as to
send nine different telegraph messages at the same instant, each set of
instruments depending on its selective note, while any intermediate office
could pick up the message for itself by simply tuning its relays to the
keynote required. Theoretically the system could be split up into any
number of notes and semi-tones. Practically it served as the basis of some
real telegraphic work, but is not now in use. Any one can realize, however,
that it did not take so acute and ingenious a mind very long to push forward
to the telephone, as a dangerous competitor with Bell, who had also, like
Edison, been working assiduously in the field of acoustic and multiple
telegraphs. Seen in the retrospect, the struggle for the goal at this moment
was one of the memorable incidents in electrical history.
Among the interesting papers filed at the Orange Laboratory is a
lithograph, the size of an ordinary patent drawing, headed "First Telephone
on Record." The claim thus made goes back to the period when all was war,
and when dispute was hot and rife as to the actual invention of the
telephone. The device shown, made by Edison in 1875, was actually
included in a caveat filed January 14, 1876, a month before Bell or Gray. It
shows a little solenoid arrangement, with one end of the plunger attached to
the diaphragm of a speaking or resonating chamber. Edison states that while

Page 125
the device is crudely capable of use as a magneto telephone, he did not
invent it for transmitting speech, but as an apparatus for analyzing the
complex waves arising from various sounds. It was made in pursuance of
his investigations into the subject of harmonic telegraphs. He did not try the
effect of sound-waves produced by the human voice until Bell came
forward a few months later; but he found then that this device, made in
1875, was capable of use as a telephone. In his testimony and public
utterances Edison has always given Bell credit for the discovery of the
transmission of articulate speech by talking against a diaphragm placed in
front of an electromagnet; but it is only proper here to note, in passing, the
curious fact that he had actually produced a device that COULD talk, prior
to 1876, and was therefore very close to Bell, who took the one great step
further. A strong characterization of the value and importance of the work
done by Edison in the development of the carbon transmitter will be found
in the decision of Judge Brown in the United States Circuit Court of
Appeals, sitting in Boston, on February 27, 1901, declaring void the famous
Berliner patent of the Bell telephone system. [5]
[Footnote 5: See Federal Reporter, vol. 109, p. 976 et seq.]
Bell's patent of 1876 was of an all-embracing character, which only the
make-and-break principle, if practical, could have escaped. It was pointed
out in the patent that Bell discovered the great principle that electrical
undulations induced by the vibrations of a current produced by sound-
waves can be represented graphically by the same sinusoidal curve that
expresses the original sound vibrations themselves; or, in other words, that
a curve representing sound vibrations will correspond precisely to a curve
representing electric impulses produced or generated by those identical
sound vibrations—as, for example, when the latter impinge upon a
diaphragm acting as an armature of an electromagnet, and which by
movement to and fro sets up the electric impulses by induction. To speak
plainly, the electric impulses correspond in form and character to the sound
vibration which they represent. This reduced to a patent "claim" governed
the art as firmly as a papal bull for centuries enabled Spain to hold the
Western world. The language of the claim is: "The method of and apparatus
for transmitting vocal or other sounds telegraphically as herein described,
by causing electrical undulations similar in form to the vibrations of the air
accompanying the said vocal or other sounds substantially as set forth." It

Page 126
was a long time, however, before the inclusive nature of this grant over
every possible telephone was understood or recognized, and litigation for
and against the patent lasted during its entire life. At the outset, the
commercial value of the telephone was little appreciated by the public, and
Bell had the greatest difficulty in securing capital; but among far-sighted
inventors there was an immediate "rush to the gold fields." Bell's first
apparatus was poor, the results being described by himself as
"unsatisfactory and discouraging," which was almost as true of the devices
he exhibited at the Philadelphia Centennial. The new-comers, like Edison,
Berliner, Blake, Hughes, Gray, Dolbear, and others, brought a wealth of
ideas, a fund of mechanical ingenuity, and an inventive ability which soon
made the telephone one of the most notable gains of the century, and one of
the most valuable additions to human resources. The work that Edison did
was, as usual, marked by infinite variety of method as well as by the power
to seize on the one needed element of practical success. Every one of the six
million telephones in use in the United States, and of the other millions in
use through out the world, bears the imprint of his genius, as at one time the
instruments bore his stamped name. For years his name was branded on
every Bell telephone set, and his patents were a mainstay of what has been
popularly called the "Bell monopoly." Speaking of his own efforts in this
field, Mr. Edison says:
"In 1876 I started again to experiment for the Western Union and Mr.
Orton. This time it was the telephone. Bell invented the first telephone,
which consisted of the present receiver, used both as a transmitter and a
receiver (the magneto type). It was attempted to introduce it commercially,
but it failed on account of its faintness and the extraneous sounds which
came in on its wires from various causes. Mr. Orton wanted me to take hold
of it and make it commercial. As I had also been working on a telegraph
system employing tuning-forks, simultaneously with both Bell and Gray, I
was pretty familiar with the subject. I started in, and soon produced the
carbon transmitter, which is now universally used.
"Tests were made between New York and Philadelphia, also between
New York and Washington, using regular Western Union wires. The noises
were so great that not a word could be heard with the Bell receiver when
used as a transmitter between New York and Newark, New Jersey. Mr.
Orton and W. K. Vanderbilt and the board of directors witnessed and took
part in the tests. The Western Union then put them on private lines. Mr.

Page 127
Theodore Puskas, of Budapest, Hungary, was the first man to suggest a
telephone exchange, and soon after exchanges were established. The
telephone department was put in the hands of Hamilton McK. Twombly,
Vanderbilt's ablest son-in-law, who made a success of it. The Bell company,
of Boston, also started an exchange, and the fight was on, the Western
Union pirating the Bell receiver, and the Boston company pirating the
Western Union transmitter. About this time I wanted to be taken care of. I
threw out hints of this desire. Then Mr. Orton sent for me. He had learned
that inventors didn't do business by the regular process, and concluded he
would close it right up. He asked me how much I wanted. I had made up
my mind it was certainly worth $25,000, if it ever amounted to anything for
central-station work, so that was the sum I had in mind to stick to and get—
obstinately. Still it had been an easy job, and only required a few months,
and I felt a little shaky and uncertain. So I asked him to make me an offer.
He promptly said he would give me $100,000. 'All right,' I said. 'It is yours
on one condition, and that is that you do not pay it all at once, but pay me at
the rate of $6000 per year for seventeen years'—the life of the patent. He
seemed only too pleased to do this, and it was closed. My ambition was
about four times too large for my business capacity, and I knew that I would
soon spend this money experimenting if I got it all at once, so I fixed it that
I couldn't. I saved seventeen years of worry by this stroke."
Thus modestly is told the debut of Edison in the telephone art, to which
with his carbon transmitter he gave the valuable principle of varying the
resistance of the transmitting circuit with changes in the pressure, as well as
the vital practice of using the induction coil as a means of increasing the
effective length of the talking circuit. Without these, modern telephony
would not and could not exist. [6] But Edison, in telephonic work, as in
other directions, was remarkably fertile and prolific. His first inventions in
the art, made in 1875-76, continue through many later years, including all
kinds of carbon instruments —the water telephone, electrostatic telephone,
condenser telephone, chemical telephone, various magneto telephones,
inertia telephone, mercury telephone, voltaic pile telephone, musical
transmitter, and the electromotograph. All were actually made and tested.
[Footnote 6: Briefly stated, the essential difference
between Bell's telephone and Edison's is this: With the
former the sound vibrations impinge upon a steel diaphragm
arranged adjacent to the pole of a bar electromagnet,
whereby the diaphragm acts as an armature, and by its
telephone exchange, and soon after exchanges were established. The
telephone department was put in the hands of Hamilton McK. Twombly,

[Footnote 6: Briefly stated, the essential difference
between Bell's telephone and Edison's is this: With the
former the sound vibrations impinge upon a steel diaphragm
arranged adjacent to the pole of a bar electromagnet,
whereby the diaphragm acts as an armature, and by its
Page 128
vibrations induces very weak electric impulses in the
magnetic coil. These impulses, according to Bell's theory,
correspond in form to the sound-waves, and passing over the
line energize the magnet coil at the receiving end, and by
varying the magnetism cause the receiving diaphragm to be
similarly vibrated to reproduce the sounds. A single
apparatus is therefore used at each end, performing the
double function of transmitter and receiver. With Edison's
telephone a closed circuit is used on which is constantly
flowing a battery current, and included in that circuit is a
pair of electrodes, one or both of which is of carbon. These
electrodes are always in contact with a certain initial
pressure, so that current will be always flowing over the
circuit. One of the electrodes is connected with the
diaphragm on which the sound-waves impinge, and the
vibration of this diaphragm causes the pressure between the
electrodes to be correspondingly varied, and thereby effects
a variation in the current, resulting in the production of
impulses which actuate the receiving magnet. In other words,
with Bell's telephone the sound-waves themselves generate
the electric impulses, which are hence extremely faint. With
the Edison telephone, the sound-waves actuate an electric
valve, so to speak, and permit variations in a current of
any desired strength.
A second distinction between the two telephones is this:
With the Bell apparatus the very weak electric impulses
generated by the vibration of the transmitting diaphragm
pass over the entire line to the receiving end, and in
consequence the permissible length of line is limited to a
few miles under ideal conditions. With Edison's telephone
the battery current does not flow on the main line, but
passes through the primary circuit of an induction coil, by
which corresponding impulses of enormously higher potential
are sent out on the main line to the receiving end. In
consequence, the line may be hundreds of miles in length. No
modern telephone system in use to-day lacks these
characteristic features—the varying resistance and the
induction coil.]
The principle of the electromotograph was utilized by Edison in more
ways than one, first of all in telegraphy at this juncture. The well-known
Page patent, which had lingered in the Patent Office for years, had just been
issued, and was considered a formidable weapon. It related to the use of a
retractile spring to withdraw the armature lever from the magnet of a
telegraph or other relay or sounder, and thus controlled the art of telegraphy,
except in simple circuits. "There was no known way," remarks Edison,
"whereby this patent could be evaded, and its possessor would eventually
control the use of what is known as the relay and sounder, and this was vital
to telegraphy. Gould was pounding the Western Union on the Stock
Exchange, disturbing its railroad contracts, and, being advised by his
lawyers that this patent was of great value, bought it. The moment Mr.
Orton heard this he sent for me and explained the situation, and wanted me
magnetic coil. These impulses, according to Bell's theory,
correspond in form to the sound-waves, and passing over the

varying the magnetism cause the receiving diaphragm to be
similarly vibrated to reproduce the sounds. A single

Orton heard this he sent for me and explained the situation, and wanted me
Page 129
to go to work immediately and see if I couldn't evade it or discover some
other means that could be used in case Gould sustained the patent. It
seemed a pretty hard job, because there was no known means of moving a
lever at the other end of a telegraph wire except by the use of a magnet. I
said I would go at it that night. In experimenting some years previously, I
had discovered a very peculiar phenomenon, and that was that if a piece of
metal connected to a battery was rubbed over a moistened piece of chalk
resting on a metal connected to the other pole, when the current passed the
friction was greatly diminished. When the current was reversed the friction
was greatly increased over what it was when no current was passing.
Remembering this, I substituted a piece of chalk rotated by a small electric
motor for the magnet, and connecting a sounder to a metallic finger resting
on the chalk, the combination claim of Page was made worthless. A hitherto
unknown means was introduced in the electric art. Two or three of the
devices were made and tested by the company's expert. Mr. Orton, after he
had me sign the patent application and got it in the Patent Office, wanted to
settle for it at once. He asked my price. Again I said: 'Make me an offer.'
Again he named $100,000. I accepted, providing he would pay it at the rate
of $6000 a year for seventeen years. This was done, and thus, with the
telephone money, I received $12,000 yearly for that period from the
Western Union Telegraph Company."
A year or two later the motograph cropped up again in Edison's work in a
curious manner. The telephone was being developed in England, and Edison
had made arrangements with Colonel Gouraud, his old associate in the
automatic telegraph, to represent his interests. A company was formed, a
large number of instruments were made and sent to Gouraud in London,
and prospects were bright. Then there came a threat of litigation from the
owners of the Bell patent, and Gouraud found he could not push the
enterprise unless he could avoid using what was asserted to be an
infringement of the Bell receiver. He cabled for help to Edison, who sent
back word telling him to hold the fort. "I had recourse again," says Edison,
"to the phenomenon discovered by me years previous, that the friction of a
rubbing electrode passing over a moist chalk surface was varied by
electricity. I devised a telephone receiver which was afterward known as the
'loud-speaking telephone,' or 'chalk receiver.' There was no magnet, simply
a diaphragm and a cylinder of compressed chalk about the size of a thimble.
A thin spring connected to the centre of the diaphragm extended outwardly
other means that could be used in case Gould sustained the patent. It
seemed a pretty hard job, because there was no known means of moving a
lever at the other end of a telegraph wire except by the use of a magnet. I
said I would go at it that night. In experimenting some years previously, I

and prospects were bright. Then there came a threat of litigation from the
owners of the Bell patent, and Gouraud found he could not push the
enterprise unless he could avoid using what was asserted to be an
infringement of the Bell receiver. He cabled for help to Edison, who sent
back word telling him to hold the fort. "I had recourse again," says Edison,
"to the phenomenon discovered by me years previous, that the friction of a
rubbing electrode passing over a moist chalk surface was varied by
electricity. I devised a telephone receiver which was afterward known as the
'loud-speaking telephone,' or 'chalk receiver.' There was no magnet, simply
a diaphragm and a cylinder of compressed chalk about the size of a thimble.
A thin spring connected to the centre of the diaphragm extended outwardly
Page 130
and rested on the chalk cylinder, and was pressed against it with a pressure
equal to that which would be due to a weight of about six pounds. The chalk
was rotated by hand. The volume of sound was very great. A person talking
into the carbon transmitter in New York had his voice so amplified that he
could be heard one thousand feet away in an open field at Menlo Park. This
great excess of power was due to the fact that the latter came from the
person turning the handle. The voice, instead of furnishing all the power as
with the present receiver, merely controlled the power, just as an engineer
working a valve would control a powerful engine.
"I made six of these receivers and sent them in charge of an expert on the
first steamer. They were welcomed and tested, and shortly afterward I
shipped a hundred more. At the same time I was ordered to send twenty
young men, after teaching them to become expert. I set up an exchange,
around the laboratory, of ten instruments. I would then go out and get each
one out of order in every conceivable way, cutting the wires of one, short-
circuiting another, destroying the adjustment of a third, putting dirt between
the electrodes of a fourth, and so on. A man would be sent to each to find
out the trouble. When he could find the trouble ten consecutive times, using
five minutes each, he was sent to London. About sixty men were sifted to
get twenty. Before all had arrived, the Bell company there, seeing we could
not be stopped, entered into negotiations for consolidation. One day I
received a cable from Gouraud offering '30,000' for my interest. I cabled
back I would accept. When the draft came I was astonished to find it was
for L30,000. I had thought it was dollars."
In regard to this singular and happy conclusion, Edison makes some
interesting comments as to the attitude of the courts toward inventors, and
the difference between American and English courts. "The men I sent over
were used to establish telephone exchanges all over the Continent, and
some of them became wealthy. It was among this crowd in London that
Bernard Shaw was employed before he became famous. The chalk
telephone was finally discarded in favor of the Bell receiver—the latter
being more simple and cheaper. Extensive litigation with new-comers
followed. My carbon-transmitter patent was sustained, and preserved the
monopoly of the telephone in England for many years. Bell's patent was not
sustained by the courts. Sir Richard Webster, now Chief-Justice of England,
was my counsel, and sustained all of my patents in England for many years.
Webster has a marvellous capacity for understanding things scientific; and
equal to that which would be due to a weight of about six pounds. The chalk

Webster has a marvellous capacity for understanding things scientific; and
Page 131
his address before the courts was lucidity itself. His brain is highly
organized. My experience with the legal fraternity is that scientific subjects
are distasteful to them, and it is rare in this country, on account of the
system of trying patent suits, for a judge really to reach the meat of the
controversy, and inventors scarcely ever get a decision squarely and entirely
in their favor. The fault rests, in my judgment, almost wholly with the
system under which testimony to the extent of thousands of pages bearing
on all conceivable subjects, many of them having no possible connection
with the invention in dispute, is presented to an over-worked judge in an
hour or two of argument supported by several hundred pages of briefs; and
the judge is supposed to extract some essence of justice from this mass of
conflicting, blind, and misleading statements. It is a human impossibility,
no matter how able and fair-minded the judge may be. In England the case
is different. There the judges are face to face with the experts and other
witnesses. They get the testimony first-hand and only so much as they need,
and there are no long-winded briefs and arguments, and the case is decided
then and there, a few months perhaps after suit is brought, instead of many
years afterward, as in this country. And in England, when a case is once
finally decided it is settled for the whole country, while here it is not so.
Here a patent having once been sustained, say, in Boston, may have to be
litigated all over again in New York, and again in Philadelphia, and so on
for all the Federal circuits. Furthermore, it seems to me that scientific
disputes should be decided by some court containing at least one or two
scientific men—men capable of comprehending the significance of an
invention and the difficulties of its accomplishment—if justice is ever to be
given to an inventor. And I think, also, that this court should have the power
to summon before it and examine any recognized expert in the special art,
who might be able to testify to FACTS for or against the patent, instead of
trying to gather the truth from the tedious essays of hired experts, whose
depositions are really nothing but sworn arguments. The real gist of patent
suits is generally very simple, and I have no doubt that any judge of fair
intelligence, assisted by one or more scientific advisers, could in a couple of
days at the most examine all the necessary witnesses; hear all the necessary
arguments, and actually decide an ordinary patent suit in a way that would
more nearly be just, than can now be done at an expenditure of a hundred
times as much money and months and years of preparation. And I have no
doubt that the time taken by the court would be enormously less, because if
organized. My experience with the legal fraternity is that scientific subjects
are distasteful to them, and it is rare in this country, on account of the

a judge attempts to read the bulky records and briefs, that work alone would
require several days.
"Acting as judges, inventors would not be very apt to correctly decide a
complicated law point; and on the other hand, it is hard to see how a lawyer
can decide a complicated scientific point rightly. Some inventors complain
of our Patent Office, but my own experience with the Patent Office is that
the examiners are fair-minded and intelligent, and when they refuse a patent
they are generally right; but I think the whole trouble lies with the system in
vogue in the Federal courts for trying patent suits, and in the fact, which
cannot be disputed, that the Federal judges, with but few exceptions, do not
comprehend complicated scientific questions. To secure uniformity in the
several Federal circuits and correct errors, it has been proposed to establish
a central court of patent appeals in Washington. This I believe in; but this
court should also contain at least two scientific men, who would not be
blind to the sophistry of paid experts. [7] Men whose inventions would have
created wealth of millions have been ruined and prevented from making any
money whereby they could continue their careers as creators of wealth for
the general good, just because the experts befuddled the judge by their
misleading statements."

expert evidence in patent cases, the reader will probably be
interested in perusing the following extracts from the
opinion of Judge Dayton, in the suit of Bryce Bros. Co. vs.
Seneca Glass Co., tried in the United States Circuit Court,
Northern District of West Virginia, reported in The Federal
Reporter, 140, page 161:
"On this subject of the validity of this patent, a vast
amount of conflicting, technical, perplexing, and almost
hypercritical discussion and opinion has been indulged, both
in the testimony and in the able and exhaustive arguments

setting forth minutely his superior qualifications
mechanical education, and great experience, takes up in
detail the patent claims, and shows to his own entire
satisfaction that none of them are new; that all of them
have been applied, under one form or another, in some
twenty-two previous patents, and in two other machines, not
patented, to-wit, the Central Glass and Kuny Kahbel ones;
that the whole machine is only 'an aggregation of well-known
mechanical elements that any skilled designer would bring to
his use in the construction of such a machine.' This
certainly, under ordinary conditions, would settle the
matter beyond peradventure; for this witness is a very wise
and learned man in these things, and very positive. But
expert Clarke appears for the plaintiff, and after setting
forth just as minutely his superior qualifications,

expert Clarke appears for the plaintiff, and after setting

Page 133
mechanical education, and great experience, which appear
fully equal in all respects to those of expert Osborn,
proceeds to take up in detail the patent claims, and shows
to his entire satisfaction that all, with possibly one
exception, are new, show inventive genius, and distinct
advances upon the prior art. In the most lucid, and even
fascinating, way he discusses all the parts of this machine,
compares it with the others, draws distinctions, points out
the merits of the one in controversy and the defects of all
the others, considers the twenty-odd patents referred to by
Osborn, and in the politest, but neatest, manner imaginable
shows that expert Osborn did not know what he was talking
about, and sums the whole matter up by declaring this
'invention of Mr. Schrader's, as embodied in the patent in
suit, a radical and wide departure, from the Kahbel machine'
(admitted on all sides to be nearest prior approach to it),
'a distinct and important advance in the art of engraving
glassware, and generally a machine for this purpose which
has involved the exercise of the inventive faculty in the
highest degree.'
"Thus a more radical and irreconcilable disagreement between
experts touching the same thing could hardly be found. So it
is with the testimony. If we take that for the defendant,
the Central Glass Company machine, and especially the Kuny
Kahbel machine, built and operated years before this patent
issued, and not patented, are just as good, just as
effective and practical, as this one, and capable of turning
out just as perfect work and as great a variety of it. On
the other hand, if we take that produced by the plaintiff,
we are driven to the conclusion that these prior machines,
the product of the same mind, were only progressive steps
forward from utter darkness, so to speak, into full
inventive sunlight, which made clear to him the solution of
the problem in this patented machine. The shortcomings of
the earlier machines are minutely set forth, and the
witnesses for the plaintiff are clear that they are neither
practical nor profitable.
"But this is not all of the trouble that confronts us in
this case. Counsel of both sides, with an indomitable
courage that must command admiration, a courage that has led
them to a vast amount of study, investigation, and thought,
that in fact has made them all experts, have dissected this
record of 356 closely printed pages, applied all mechanical
principles and laws to the facts as they see them, and,
besides, have ransacked the law-books and cited an enormous
number of cases, more or less in point, as illustration of
their respective contentions. The courts find nothing more
difficult than to apply an abstract principle to all classes
of cases that may arise. The facts in each case so
frequently create an exception to the general rule that such
rule must be honored rather in its breach than in its
observance. Therefore, after a careful examination of these
cases, it is no criticism of the courts to say that both
sides have found abundant and about an equal amount of
authority to sustain their respective contentions, and, as a
result, counsel have submitted, in briefs, a sum total of
225 closely printed pages, in which they have clearly, yet,
almost to a mathematical certainty, demonstrated on the one
side that this Schrader machine is new and patentable, and
fully equal in all respects to those of expert Osborn,
proceeds to take up in detail the patent claims, and shows

Mr. Bernard Shaw, the distinguished English author, has given a most
vivid and amusing picture of this introduction of Edison's telephone into
England, describing the apparatus as "a much too ingenious invention,
being nothing less than a telephone of such stentorian efficiency that it
bellowed your most private communications all over the house, instead of
whispering them with some sort of discretion." Shaw, as a young man, was
employed by the Edison Telephone Company, and was very much alive to
his surroundings, often assisting in public demonstrations of the apparatus
"in a manner which I am persuaded laid the foundation of Mr. Edison's
reputation." The sketch of the men sent over from America is graphic:
"Whilst the Edison Telephone Company lasted it crowded the basement of a
high pile of offices in Queen Victoria Street with American artificers. These
deluded and romantic men gave me a glimpse of the skilled proletariat of
the United States. They sang obsolete sentimental songs with genuine
emotion; and their language was frightful even to an Irishman. They worked
with a ferocious energy which was out of all proportion to the actual result
achieved. Indomitably resolved to assert their republican manhood by
taking no orders from a tall-hatted Englishman whose stiff politeness
covered his conviction that they were relatively to himself inferior and
common persons, they insisted on being slave-driven with genuine
American oaths by a genuine free and equal American foreman. They
utterly despised the artfully slow British workman, who did as little for his
wages as he possibly could; never hurried himself; and had a deep
reverence for one whose pocket could be tapped by respectful behavior.
Need I add that they were contemptuously wondered at by this same British
workman as a parcel of outlandish adult boys who sweated themselves for
their employer's benefit instead of looking after their own interest? They
adored Mr. Edison as the greatest man of all time in every possible
department of science, art, and philosophy, and execrated Mr. Graham Bell,
the inventor of the rival telephone, as his Satanic adversary; but each of
them had (or intended to have) on the brink of completion an improvement
on the telephone, usually a new transmitter. They were free-souled

creatures, excellent company, sensitive, cheerful, and profane; liars,

never left them even when, as often happened, they were wrestling with
difficulties of their own making, or struggling in no-thoroughfares, from
which they had to be retrieved like stray sheep by Englishmen without
imagination enough to go wrong."
Mr. Samuel Insull, who afterward became private secretary to Mr.
Edison, and a leader in the development of American electrical
manufacturing and the central-station art, was also in close touch with the
London situation thus depicted, being at the time private secretary to
Colonel Gouraud, and acting for the first half hour as the amateur telephone
operator in the first experimental exchange erected in Europe. He took
notes of an early meeting where the affairs of the company were discussed
by leading men like Sir John Lubbock (Lord Avebury) and the Right Hon.
E. P. Bouverie (then a cabinet minister), none of whom could see in the
telephone much more than an auxiliary for getting out promptly in the next
morning's papers the midnight debates in Parliament. "I remember another
incident," says Mr. Insull. "It was at some celebration of one of the Royal
Societies at the Burlington House, Piccadilly. We had a telephone line
running across the roofs to the basement of the building. I think it was to
Tyndall's laboratory in Burlington Street. As the ladies and gentlemen came
through, they naturally wanted to look at the great curiosity, the loud-
speaking telephone: in fact, any telephone was a curiosity then. Mr. and
Mrs. Gladstone came through. I was handling the telephone at the
Burlington House end. Mrs. Gladstone asked the man over the telephone
whether he knew if a man or woman was speaking; and the reply came in
quite loud tones that it was a man!"
With Mr. E. H. Johnson, who represented Edison, there went to England
for the furtherance of this telephone enterprise, Mr. Charles Edison, a
nephew of the inventor. He died in Paris, October, 1879, not twenty years of
age. Stimulated by the example of his uncle, this brilliant youth had already
made a mark for himself as a student and inventor, and when only eighteen
he secured in open competition the contract to install a complete fire-alarm
telegraph system for Port Huron. A few months later he was eagerly
welcomed by his uncle at Menlo Park, and after working on the telephone
was sent to London to aid in its introduction. There he made the
acquaintance of Professor Tyndall, exhibited the telephone to the late King
braggarts, and hustlers, with an air of making slow old England hum, which
never left them even when, as often happened, they were wrestling with

acquaintance of Professor Tyndall, exhibited the telephone to the late King
Page 136
of England; and also won the friendship of the late King of the Belgians,
with whom he took up the project of establishing telephonic communication
between Belgium and England. At the time of his premature death he was
engaged in installing the Edison quadruplex between Brussels and Paris,
being one of the very few persons then in Europe familiar with the working
of that invention.
Meantime, the telephonic art in America was undergoing very rapid
development. In March, 1878, addressing "the capitalists of the Electric
Telephone Company" on the future of his invention, Bell outlined with
prophetic foresight and remarkable clearness the coming of the modern
telephone exchange. Comparing with gas and water distribution, he said:
"In a similar manner, it is conceivable that cables of telephone wires could
be laid underground or suspended overhead communicating by branch
wires with private dwellings, country houses, shops, manufactories, etc.,
uniting them through the main cable with a central office, where the wire
could be connected as desired, establishing direct communication between
any two places in the city.... Not only so, but I believe, in the future, wires
will unite the head offices of telephone companies in different cities; and a
man in one part of the country may communicate by word of mouth with
another in a distant place."
All of which has come to pass. Professor Bell also suggested how this
could be done by "the employ of a man in each central office for the
purpose of connecting the wires as directed." He also indicated the two
methods of telephonic tariff—a fixed rental and a toll; and mentioned the
practice, now in use on long-distance lines, of a time charge. As a matter of
fact, this "centralizing" was attempted in May, 1877, in Boston, with the
circuits of the Holmes burglar-alarm system, four banking-houses being
thus interconnected; while in January of 1878 the Bell telephone central-
office system at New Haven, Connecticut, was opened for business, "the
first fully equipped commercial telephone exchange ever established for
public or general service."
All through this formative period Bell had adhered to and introduced the
magneto form of telephone, now used only as a receiver, and very poorly
adapted for the vital function of a speech-transmitter. From August, 1877,
the Western Union Telegraph Company worked along the other line, and in
1878, with its allied Gold & Stock Telegraph Company, it brought into
with whom he took up the project of establishing telephonic communication
between Belgium and England. At the time of his premature death he was
engaged in installing the Edison quadruplex between Brussels and Paris,
being one of the very few persons then in Europe familiar with the working
of that invention.
Meantime, the telephonic art in America was undergoing very rapid
development. In March, 1878, addressing "the capitalists of the Electric
Telephone Company" on the future of his invention, Bell outlined with
prophetic foresight and remarkable clearness the coming of the modern
telephone exchange. Comparing with gas and water distribution, he said:
"In a similar manner, it is conceivable that cables of telephone wires could
be laid underground or suspended overhead communicating by branch
wires with private dwellings, country houses, shops, manufactories, etc.,
uniting them through the main cable with a central office, where the wire
could be connected as desired, establishing direct communication between
any two places in the city.... Not only so, but I believe, in the future, wires

All through this formative period Bell had adhered to and introduced the

adapted for the vital function of a speech-transmitter. From August, 1877,
the Western Union Telegraph Company worked along the other line, and in
1878, with its allied Gold & Stock Telegraph Company, it brought into
Page 137
existence the American Speaking Telephone Company to introduce the
Edison apparatus, and to create telephone exchanges all over the country. In
this warfare, the possession of a good battery transmitter counted very
heavily in favor of the Western Union, for upon that the real expansion of
the whole industry depended; but in a few months the Bell system had its
battery transmitter, too, tending to equalize matters. Late in the same year
patent litigation was begun which brought out clearly the merits of Bell,
through his patent, as the original and first inventor of the electric speaking
telephone; and the Western Union Telegraph Company made terms with its
rival. A famous contract bearing date of November 10, 1879, showed that
under the Edison and other controlling patents the Western Union Company
had already set going some eighty-five exchanges, and was making large
quantities of telephonic apparatus. In return for its voluntary retirement
from the telephonic field, the Western Union Telegraph Company, under
this contract, received a royalty of 20 per cent. of all the telephone earnings
of the Bell system while the Bell patents ran; and thus came to enjoy an
annual income of several hundred thousand dollars for some years, based
chiefly on its modest investment in Edison's work. It was also paid several
thousand dollars in cash for the Edison, Phelps, Gray, and other apparatus
on hand. It secured further 40 per cent. of the stock of the local telephone
systems of New York and Chicago; and last, but by no means least, it
exacted from the Bell interests an agreement to stay out of the telegraph
field.
By March, 1881, there were in the United States only nine cities of more
than ten thousand inhabitants, and only one of more than fifteen thousand,
without a telephone exchange. The industry thrived under competition, and
the absence of it now had a decided effect in checking growth; for when the
Bell patent expired in 1893, the total of telephone sets in operation in the
United States was only 291,253. To quote from an official Bell statement:
"The brief but vigorous Western Union competition was a kind of
blessing in disguise. The very fact that two distinct interests were actively
engaged in the work of organizing and establishing competing telephone
exchanges all over the country, greatly facilitated the spread of the idea and
the growth of the business, and familiarized the people with the use of the
telephone as a business agency; while the keenness of the competition,
extending to the agents and employees of both companies, brought about a
swift but quite unforeseen and unlooked-for expansion in the individual
Edison apparatus, and to create telephone exchanges all over the country. In

exchanges of the larger cities, and a corresponding advance in their
importance, value, and usefulness."
The truth of this was immediately shown in 1894, after the Bell patents
had expired, by the tremendous outburst of new competitive activity, in
"independent" country systems and toll lines through sparsely settled
districts—work for which the Edison apparatus and methods were
peculiarly adapted, yet against which the influence of the Edison patent was
invoked. The data secured by the United States Census Office in 1902
showed that the whole industry had made gigantic leaps in eight years, and
had 2,371,044 telephone stations in service, of which 1,053,866 were
wholly or nominally independent of the Bell. By 1907 an even more notable
increase was shown, and the Census figures for that year included no fewer
than 6,118,578 stations, of which 1,986,575 were "independent." These six
million instruments every single set employing the principle of the carbon
transmitter—were grouped into 15,527 public exchanges, in the very
manner predicted by Bell thirty years before, and they gave service in the
shape of over eleven billions of talks. The outstanding capitalized value of
the plant was $814,616,004, the income for the year was nearly
$185,000,000, and the people employed were 140,000. If Edison had done
nothing else, his share in the creation of such an industry would have
entitled him to a high place among inventors.
This chapter is of necessity brief in its reference to many extremely
interesting points and details; and to some readers it may seem incomplete
in its references to the work of other men than Edison, whose influence on
telephony as an art has also been considerable. In reply to this pertinent
criticism, it may be pointed out that this is a life of Edison, and not of any
one else; and that even the discussion of his achievements alone in these
various fields requires more space than the authors have at their disposal.
The attempt has been made, however, to indicate the course of events and
deal fairly with the facts. The controversy that once waged with great
excitement over the invention of the microphone, but has long since died
away, is suggestive of the difficulties involved in trying to do justice to
everybody. A standard history describes the microphone thus:
"A form of apparatus produced during the early days of the telephone by
Professor Hughes, of England, for the purpose of rendering faint, indistinct
sounds distinctly audible, depended for its operation on the changes that
importance, value, and usefulness."

"A form of apparatus produced during the early days of the telephone by
Professor Hughes, of England, for the purpose of rendering faint, indistinct
sounds distinctly audible, depended for its operation on the changes that
Page 139
result in the resistance of loose contacts. This apparatus was called the
microphone, and was in reality but one of the many forms that it is possible
to give to the telephone transmitter. For example, the Edison granular
transmitter was a variety of microphone, as was also Edison's transmitter, in
which the solid button of carbon was employed. Indeed, even the platinum
point, which in the early form of the Reis transmitter pressed against the
platinum contact cemented to the centre of the diaphragm, was a
microphone."
At a time when most people were amazed at the idea of hearing, with the
aid of a "microphone," a fly walk at a distance of many miles, the priority
of invention of such a device was hotly disputed. Yet without desiring to
take anything from the credit of the brilliant American, Hughes, whose
telegraphic apparatus is still in use all over Europe, it may be pointed out
that this passage gives Edison the attribution of at least two original forms
of which those suggested by Hughes were mere variations and
modifications. With regard to this matter, Mr. Edison himself remarks:
"After I sent one of my men over to London especially, to show Preece the
carbon transmitter, and where Hughes first saw it, and heard it—then within
a month he came out with the microphone, without any acknowledgment
whatever. Published dates will show that Hughes came along after me."
There have been other ways also in which Edison has utilized the
peculiar property that carbon possesses of altering its resistance to the
passage of current, according to the pressure to which it is subjected,
whether at the surface, or through closer union of the mass. A loose road
with a few inches of dust or pebbles on it offers appreciable resistance to
the wheels of vehicles travelling over it; but if the surface is kept hard and
smooth the effect is quite different. In the same way carbon, whether solid
or in the shape of finely divided powder, offers a high resistance to the
passage of electricity; but if the carbon is squeezed together the conditions
change, with less resistance to electricity in the circuit. For his quadruplex
system, Mr. Edison utilized this fact in the construction of a rheostat or
resistance box. It consists of a series of silk disks saturated with a sizing of
plumbago and well dried. The disks are compressed by means of an
adjustable screw; and in this manner the resistance of a circuit can be varied
over a wide range.

In like manner Edison developed a "pressure" or carbon relay, adapted to
the transference of signals of variable strength from one circuit to another.
An ordinary relay consists of an electromagnet inserted in the main line for
telegraphing, which brings a local battery and sounder circuit into play,
reproducing in the local circuit the signals sent over the main line. The relay
is adjusted to the weaker currents likely to be received, but the signals
reproduced on the sounder by the agency of the relay are, of course, all of
equal strength, as they depend upon the local battery, which has only this
steady work to perform. In cases where it is desirable to reproduce the
signals in the local circuit with the same variations in strength as they are
received by the relay, the Edison carbon pressure relay does the work. The
poles of the electromagnet in the local circuit are hollowed out and filled up
with carbon disks or powdered plumbago. The armature and the carbon-
tipped poles of the electromagnet form part of the local circuit; and if the
relay is actuated by a weak current the armature will be attracted but feebly.
The carbon being only slightly compressed will offer considerable
resistance to the flow of current from the local battery, and therefore the
signal on the local sounder will be weak. If, on the contrary, the incoming
current on the main line be strong, the armature will be strongly attracted,
the carbon will be sharply compressed, the resistance in the local circuit
will be proportionately lowered, and the signal heard on the local sounder
will be a loud one. Thus it will be seen, by another clever juggle with the
willing agent, carbon, for which he has found so many duties, Edison is
able to transfer or transmit exactly, to the local circuit, the main-line current
in all its minutest variations.
In his researches to determine the nature of the motograph phenomena,
and to open up other sources of electrical current generation, Edison has
worked out a very ingenious and somewhat perplexing piece of apparatus
known as the "chalk battery." It consists of a series of chalk cylinders
mounted on a shaft revolved by hand. Resting against each of these
cylinders is a palladium-faced spring, and similar springs make contact with
the shaft between each cylinder. By connecting all these springs in circuit
with a galvanometer and revolving the shaft rapidly, a notable deflection is
obtained of the galvanometer needle, indicating the production of electrical
energy. The reason for this does not appear to have been determined.
Last but not least, in this beautiful and ingenious series, comes the
"tasimeter," an instrument of most delicate sensibility in the presence of
the transference of signals of variable strength from one circuit to another.

Page 141
heat. The name is derived from the Greek, the use of the apparatus being
primarily to measure extremely minute differences of pressure. A strip of
hard rubber with pointed ends rests perpendicularly on a platinum plate,
beneath which is a carbon button, under which again lies another platinum
plate. The two plates and the carbon button form part of an electric circuit
containing a battery and a galvanometer. The hard-rubber strip is
exceedingly sensitive to heat. The slightest degree of heat imparted to it
causes it to expand invisibly, thus increasing the pressure contact on the
carbon button and producing a variation in the resistance of the circuit,
registered immediately by the little swinging needle of the galvanometer.
The instrument is so sensitive that with a delicate galvanometer it will show
the impingement of the heat from a person's hand thirty feet away. The
suggestion to employ such an apparatus in astronomical observations occurs
at once, and it may be noted that in one instance the heat of rays of light
from the remote star Arcturus gave results.

CHAPTER X
THE PHONOGRAPH
AT the opening of the Electrical Show in New York City in October,
1908, to celebrate the jubilee of the Atlantic Cable and the first quarter
century of lighting with the Edison service on Manhattan Island, the
exercises were all conducted by means of the Edison phonograph. This
included the dedicatory speech of Governor Hughes, of New York; the
modest remarks of Mr. Edison, as president; the congratulations of the
presidents of several national electric bodies, and a number of vocal and
instrumental selections of operatic nature. All this was heard clearly by a
very large audience, and was repeated on other evenings. The same
speeches were used again phonographically at the Electrical Show in
Chicago in 1909—and now the records are preserved for reproduction a
hundred or a thousand years hence. This tour de force, never attempted
before, was merely an exemplification of the value of the phonograph not
only in establishing at first hand the facts of history, but in preserving the
human voice. What would we not give to listen to the very accents and
tones of the Sermon on the Mount, the orations of Demosthenes, the first
Pitt's appeal for American liberty, the Farewell of Washington, or the
Address at Gettysburg? Until Edison made his wonderful invention in 1877,
the human race was entirely without means for preserving or passing on to
posterity its own linguistic utterances or any other vocal sound. We have
some idea how the ancients looked and felt and wrote; the abundant
evidence takes us back to the cave-dwellers. But all the old languages are
dead, and the literary form is their embalmment. We do not even know
definitely how Shakespeare's and Goldsmith's plays were pronounced on
the stage in the theatres of the time; while it is only a guess that perhaps
Chaucer would sound much more modern than he scans.
The analysis of sound, which owes so much to Helmholtz, was one step
toward recording; and the various means of illustrating the phenomena of
sound to the eye and ear, prior to the phonograph, were all ingenious. One
can watch the dancing little flames of Koenig, and see a voice expressed in

The analysis of sound, which owes so much to Helmholtz, was one step

sound to the eye and ear, prior to the phonograph, were all ingenious. One
can watch the dancing little flames of Koenig, and see a voice expressed in
Page 144
tongues of fire; but the record can only be photographic. In like manner, the
simple phonautograph of Leon Scott, invented about 1858, records on a
revolving cylinder of blackened paper the sound vibrations transmitted
through a membrane to which a tiny stylus is attached; so that a human
mouth uses a pen and inscribes its sign vocal. Yet after all we are just as far
away as ever from enabling the young actors at Harvard to give
Aristophanes with all the true, subtle intonation and inflection of the Athens
of 400 B.C. The instrument is dumb. Ingenuity has been shown also in the
invention of "talking-machines," like Faber's, based on the reed organ pipe.
These automata can be made by dexterous manipulation to jabber a little,
like a doll with its monotonous "ma-ma," or a cuckoo clock; but they lack
even the sterile utility of the imitative art of ventriloquism. The real great
invention lies in creating devices that shall be able to evoke from tinfoil,
wax, or composition at any time to-day or in the future the sound that once
was as evanescent as the vibrations it made on the air.
Contrary to the general notion, very few of the great modern inventions
have been the result of a sudden inspiration by which, Minerva-like, they
have sprung full-fledged from their creators' brain; but, on the contrary, they
have been evolved by slow and gradual steps, so that frequently the final
advance has been often almost imperceptible. The Edison phonograph is an
important exception to the general rule; not, of course, the phonograph of
the present day with all of its mechanical perfection, but as an instrument
capable of recording and reproducing sound. Its invention has been
frequently attributed to the discovery that a point attached to a telephone
diaphragm would, under the effect of sound-waves, vibrate with sufficient
force to prick the finger. The story, though interesting, is not founded on
fact; but, if true, it is difficult to see how the discovery in question could
have contributed materially to the ultimate accomplishment. To a man of
Edison's perception it is absurd to suppose that the effect of the so-called
discovery would not have been made as a matter of deduction long before
the physical sensation was experienced. As a matter of fact, the invention of
the phonograph was the result of pure reason. Some time prior to 1877,
Edison had been experimenting on an automatic telegraph in which the
letters were formed by embossing strips of paper with the proper
arrangement of dots and dashes. By drawing this strip beneath a contact
lever, the latter was actuated so as to control the circuits and send the
desired signals over the line. It was observed that when the strip was moved

revolving cylinder of blackened paper the sound vibrations transmitted
through a membrane to which a tiny stylus is attached; so that a human
mouth uses a pen and inscribes its sign vocal. Yet after all we are just as far

diaphragm would, under the effect of sound-waves, vibrate with sufficient
force to prick the finger. The story, though interesting, is not founded on
fact; but, if true, it is difficult to see how the discovery in question could
have contributed materially to the ultimate accomplishment. To a man of
Edison's perception it is absurd to suppose that the effect of the so-called
discovery would not have been made as a matter of deduction long before
the physical sensation was experienced. As a matter of fact, the invention of
the phonograph was the result of pure reason. Some time prior to 1877,
Edison had been experimenting on an automatic telegraph in which the
letters were formed by embossing strips of paper with the proper
arrangement of dots and dashes. By drawing this strip beneath a contact
lever, the latter was actuated so as to control the circuits and send the
desired signals over the line. It was observed that when the strip was moved
Page 145
very rapidly the vibration of the lever resulted in the production of an
audible note. With these facts before him, Edison reasoned that if the paper
strip could be imprinted with elevations and depressions representative of
sound-waves, they might be caused to actuate a diaphragm so as to
reproduce the corresponding sounds. The next step in the line of
development was to form the necessary undulations on the strip, and it was
then reasoned that original sounds themselves might be utilized to form a
graphic record by actuating a diaphragm and causing a cutting or indenting
point carried thereby to vibrate in contact with a moving surface, so as to
cut or indent the record therein. Strange as it may seem, therefore, and
contrary to the general belief, the phonograph was developed backward, the
production of the sounds being of prior development to the idea of actually
recording them.
Mr. Edison's own account of the invention of the phonograph is intensely
interesting. "I was experimenting," he says, "on an automatic method of
recording telegraph messages on a disk of paper laid on a revolving platen,
exactly the same as the disk talking-machine of to-day. The platen had a
spiral groove on its surface, like the disk. Over this was placed a circular
disk of paper; an electromagnet with the embossing point connected to an
arm travelled over the disk; and any signals given through the magnets were
embossed on the disk of paper. If this disk was removed from the machine
and put on a similar machine provided with a contact point, the embossed
record would cause the signals to be repeated into another wire. The
ordinary speed of telegraphic signals is thirty-five to forty words a minute;
but with this machine several hundred words were possible.
"From my experiments on the telephone I knew of the power of a
diaphragm to take up sound vibrations, as I had made a little toy which,
when you recited loudly in the funnel, would work a pawl connected to the
diaphragm; and this engaging a ratchet-wheel served to give continuous
rotation to a pulley. This pulley was connected by a cord to a little paper toy
representing a man sawing wood. Hence, if one shouted: 'Mary had a little
lamb,' etc., the paper man would start sawing wood. I reached the
conclusion that if I could record the movements of the diaphragm properly,
I could cause such record to reproduce the original movements imparted to
the diaphragm by the voice, and thus succeed in recording and reproducing
the human voice.

"Instead of using a disk I designed a little machine using a cylinder
provided with grooves around the surface. Over this was to be placed
tinfoil, which easily received and recorded the movements of the
diaphragm. A sketch was made, and the piece-work price, $18, was marked
on the sketch. I was in the habit of marking the price I would pay on each
sketch. If the workman lost, I would pay his regular wages; if he made more
than the wages, he kept it. The workman who got the sketch was John
Kruesi. I didn't have much faith that it would work, expecting that I might
possibly hear a word or so that would give hope of a future for the idea.
Kruesi, when he had nearly finished it, asked what it was for. I told him I
was going to record talking, and then have the machine talk back. He
thought it absurd. However, it was finished, the foil was put on; I then
shouted 'Mary had a little lamb,' etc. I adjusted the reproducer, and the
machine reproduced it perfectly. I was never so taken aback in my life.
Everybody was astonished. I was always afraid of things that worked the
first time. Long experience proved that there were great drawbacks found
generally before they could be got commercial; but here was something
there was no doubt of."
No wonder that honest John Kruesi, as he stood and listened to the
marvellous performance of the simple little machine he had himself just
finished, ejaculated in an awe-stricken tone: "Mein Gott im Himmel!" And
yet he had already seen Edison do a few clever things. No wonder they sat
up all night fixing and adjusting it so as to get better and better results—
reciting and singing, trying each other's voices, and then listening with
involuntary awe as the words came back again and again, just as long as
they were willing to revolve the little cylinder with its dotted spiral
indentations in the tinfoil under the vibrating stylus of the reproducing
diaphragm. It took a little time to acquire the knack of turning the crank
steadily while leaning over the recorder to talk into the machine; and there
was some deftness required also in fastening down the tinfoil on the
cylinder where it was held by a pin running in a longitudinal slot. Paraffined
paper appears also to have been experimented with as an impressible
material. It is said that Carman, the foreman of the machine shop, had gone
the length of wagering Edison a box of cigars that the device would not
work. All the world knows that he lost.
The original Edison phonograph thus built by Kruesi is preserved in the
South Kensington Museum, London. That repository can certainly have no
provided with grooves around the surface. Over this was to be placed
tinfoil, which easily received and recorded the movements of the
diaphragm. A sketch was made, and the piece-work price, $18, was marked

greater treasure of its kind. But as to its immediate use, the inventor says:
"That morning I took it over to New York and walked into the office of the
Scientific American, went up to Mr. Beach's desk, and said I had something
to show him. He asked what it was. I told him I had a machine that would
record and reproduce the human voice. I opened the package, set up the
machine and recited, 'Mary had a little lamb,' etc. Then I reproduced it so
that it could be heard all over the room. They kept me at it until the crowd
got so great Mr. Beach was afraid the floor would collapse; and we were
compelled to stop. The papers next morning contained columns. None of
the writers seemed to understand how it was done. I tried to explain, it was
so very simple, but the results were so surprising they made up their minds
probably that they never would understand it—and they didn't.
"I started immediately making several larger and better machines, which
I exhibited at Menlo Park to crowds. The Pennsylvania Railroad ran special
trains. Washington people telegraphed me to come on. I took a phonograph
to Washington and exhibited it in the room of James G. Blaine's niece (Gail
Hamilton); and members of Congress and notable people of that city came
all day long until late in the evening. I made one break. I recited 'Mary,' etc.,
and another ditty:
'There was a little girl, who had a little curl
Right in the middle of her forehead;
And when she was good she was very, very good,
But when she was bad she was horrid.'
"It will be remembered that Senator Roscoe Conkling, then very
prominent, had a curl of hair on his forehead; and all the caricaturists
developed it abnormally. He was very sensitive about the subject. When he
came in he was introduced; but being rather deaf, I didn't catch his name,
but sat down and started the curl ditty. Everybody tittered, and I was told
that Mr. Conkling was displeased. About 11 o'clock at night word was
received from President Hayes that he would be very much pleased if I
would come up to the White House. I was taken there, and found Mr. Hayes
and several others waiting. Among them I remember Carl Schurz, who was
playing the piano when I entered the room. The exhibition continued till
about 12.30 A.M., when Mrs. Hayes and several other ladies, who had been
induced to get up and dress, appeared. I left at 3.30 A.M.

Page 148
phonograph. It was Bishop Vincent, who helped Lewis Miller found the
Chautauqua I exhibited it, and then he asked if he could speak a few words.
I put on a fresh foil and told him to go ahead. He commenced to recite
Biblical names with immense rapidity. On reproducing it he said: 'I am
satisfied, now. There isn't a man in the United States who could recite those
names with the same rapidity.'"
The phonograph was now fairly launched as a world sensation, and a
reference to the newspapers of 1878 will show the extent to which it and
Edison were themes of universal discussion. Some of the press notices of
the period were most amazing—and amusing. As though the real
achievements of this young man, barely thirty, were not tangible and solid
enough to justify admiration of his genius, the "yellow journalists" of the
period began busily to create an "Edison myth," with gross absurdities of
assertion and attribution from which the modest subject of it all has not yet
ceased to suffer with unthinking people. A brilliantly vicious example of
this method of treatment is to be found in the Paris Figaro of that year,
which under the appropriate title of "This Astounding Eddison" lay bare
before the French public the most startling revelations as to the inventor's
life and character. "It should be understood," said this journal, "that Mr.
Eddison does not belong to himself. He is the property of the telegraph
company which lodges him in New York at a superb hotel; keeps him on a
luxurious footing, and pays him a formidable salary so as to be the one to
know of and profit by his discoveries. The company has, in the dwelling of
Eddison, men in its employ who do not quit him for a moment, at the table,
on the street, in the laboratory. So that this wretched man, watched more
closely than ever was any malefactor, cannot even give a moment's thought
to his own private affairs without one of his guards asking him what he is
thinking about." This foolish "blague" was accompanied by a description of
Edison's new "aerophone," a steam machine which carried the voice a
distance of one and a half miles. "You speak to a jet of vapor. A friend
previously advised can answer you by the same method." Nor were
American journals backward in this wild exaggeration.
The furor had its effect in stimulating a desire everywhere on the part of
everybody to see and hear the phonograph. A small commercial
organization was formed to build and exploit the apparatus, and the shops at

Page 149
Mail and Express building now stands, and where, in a general way, under
the auspices of a talented dwarf, C. A. Cheever, the embryonic phonograph
and the crude telephone shared rooms and expenses. Gardiner G. Hubbard,
father-in-law of Alex. Graham Bell, was one of the stockholders in the
Phonograph Company, which paid Edison $10,000 cash and a 20 per cent.
royalty. This curious partnership was maintained for some time, even when
the Bell Telephone offices were removed to Reade Street, New York,
whither the phonograph went also; and was perhaps explained by the fact
that just then the ability of the phonograph as a money-maker was much
more easily demonstrated than was that of the telephone, still in its short
range magneto stage and awaiting development with the aid of the carbon
transmitter.
The earning capacity of the phonograph then, as largely now, lay in its
exhibition qualities. The royalties from Boston, ever intellectually awake
and ready for something new, ran as high as $1800 a week. In New York
there was a ceaseless demand for it, and with the aid of Hilbourne L.
Roosevelt, a famous organ builder, and uncle of ex-President Roosevelt,
concerts were given at which the phonograph was "featured." To manage
this novel show business the services of James Redpath were called into
requisition with great success. Redpath, famous as a friend and biographer
of John Brown, as a Civil War correspondent, and as founder of the
celebrated Redpath Lyceum Bureau in Boston, divided the country into
territories, each section being leased for exhibition purposes on a basis of a
percentage of the "gate money." To 203 Broadway from all over the Union
flocked a swarm of showmen, cranks, and particularly of old operators,
who, the seedier they were in appearance, the more insistent they were that
"Tom" should give them, for the sake of "Auld lang syne," this chance to
make a fortune for him and for themselves. At the top of the building was a
floor on which these novices were graduated in the use and care of the
machine, and then, with an equipment of tinfoil and other supplies, they
were sent out on the road. It was a diverting experience while it lasted. The
excitement over the phonograph was maintained for many months, until a
large proportion of the inhabitants of the country had seen it; and then the
show receipts declined and dwindled away. Many of the old operators,
taken on out of good-nature, were poor exhibitors and worse accountants,
and at last they and the machines with which they had been intrusted faded
from sight. But in the mean time Edison had learned many lessons as to this

Page 150
practical side of development that were not forgotten when the renascence
of the phonograph began a few years later, leading up to the present
enormous and steady demand for both machines and records.
It deserves to be pointed out that the phonograph has changed little in the
intervening years from the first crude instruments of 1877-78. It has simply
been refined and made more perfect in a mechanical sense. Edison was
immensely impressed with its possibilities, and greatly inclined to work
upon it, but the coming of the electric light compelled him to throw all his
energies for a time into the vast new field awaiting conquest. The original
phonograph, as briefly noted above, was rotated by hand, and the cylinder
was fed slowly longitudinally by means of a nut engaging a screw thread on
the cylinder shaft. Wrapped around the cylinder was a sheet of tinfoil, with
which engaged a small chisel-like recording needle, connected adhesively
with the centre of an iron diaphragm. Obviously, as the cylinder was turned,
the needle followed a spiral path whose pitch depended upon that of the
feed screw. Along this path a thread was cut in the cylinder so as to permit
the needle to indent the foil readily as the diaphragm vibrated. By rotating
the cylinder and by causing the diaphragm to vibrate under the effect of
vocal or musical sounds, the needle-like point would form a series of
indentations in the foil corresponding to and characteristic of the sound-
waves. By now engaging the point with the beginning of the grooved record
so formed, and by again rotating the cylinder, the undulations of the record
would cause the needle and its attached diaphragm to vibrate so as to effect
the reproduction. Such an apparatus was necessarily undeveloped, and was
interesting only from a scientific point of view. It had many mechanical
defects which prevented its use as a practical apparatus. Since the cylinder
was rotated by hand, the speed at which the record was formed would vary
considerably, even with the same manipulator, so that it would have been
impossible to record and reproduce music satisfactorily; in doing which
exact uniformity of speed is essential. The formation of the record in tinfoil
was also objectionable from a practical standpoint, since such a record was
faint and would be substantially obliterated after two or three reproductions.
Furthermore, the foil could not be easily removed from and replaced upon
the instrument, and consequently the reproduction had to follow the
recording immediately, and the successive tinfoils were thrown away. The
instrument was also heavy and bulky. Notwithstanding these objections the
original phonograph created, as already remarked, an enormous popular
of the phonograph began a few years later, leading up to the present
enormous and steady demand for both machines and records.

excitement, and the exhibitions were considered by many sceptical persons
as nothing more than clever ventriloquism. The possibilities of the
instrument as a commercial apparatus were recognized from the very first,
and some of the fields in which it was predicted that the phonograph would
be used are now fully occupied. Some have not yet been realized. Writing in
1878 in the North American-Review, Mr. Edison thus summed up his own
ideas as to the future applications of the new invention:
"Among the many uses to which the phonograph will be applied are the
following:
1. Letter writing and all kinds of dictation without the aid of a
stenographer.
2. Phonographic books, which will speak to blind people without effort
on their part.
3. The teaching of elocution.
4. Reproduction of music.
5. The 'Family Record'—a registry of sayings, reminiscences, etc., by
members of a family in their own voices, and of the last words of dying
persons.
6. Music-boxes and toys.
7. Clocks that should announce in articulate speech the time for going
home, going to meals, etc.
8. The preservation of languages by exact reproduction of the manner of
pronouncing.
9. Educational purposes; such as preserving the explanations made by a
teacher, so that the pupil can refer to them at any moment, and spelling or
other lessons placed upon the phonograph for convenience in committing to
memory.
10. Connection with the telephone, so as to make that instrument an
auxiliary in the transmission of permanent and invaluable records, instead
of being the recipient of momentary and fleeting communication."
Of the above fields of usefulness in which it was expected that the
phonograph might be applied, only three have been commercially realized
—namely, the reproduction of musical, including vaudeville or talking
selections, for which purpose a very large proportion of the phonographs
as nothing more than clever ventriloquism. The possibilities of the
instrument as a commercial apparatus were recognized from the very first,

Of the above fields of usefulness in which it was expected that the
phonograph might be applied, only three have been commercially realized
—namely, the reproduction of musical, including vaudeville or talking
selections, for which purpose a very large proportion of the phonographs
Page 152
now made is used; the employment of the machine as a mechanical
stenographer, which field has been taken up actively only within the past
few years; and the utilization of the device for the teaching of languages,
for which purpose it has been successfully employed, for example, by the
International Correspondence Schools of Scranton, Pennsylvania, for
several years. The other uses, however, which were early predicted for the
phonograph have not as yet been worked out practically, although the time
seems not far distant when its general utility will be widely enlarged. Both
dolls and clocks have been made, but thus far the world has not taken them
seriously.
The original phonograph, as invented by Edison, remained in its crude
and immature state for almost ten years—still the object of philosophical
interest, and as a convenient text-book illustration of the effect of sound
vibration. It continued to be a theme of curious interest to the imaginative,
and the subject of much fiction, while its neglected commercial possibilities
were still more or less vaguely referred to. During this period of arrested
development, Edison was continuously working on the invention and
commercial exploitation of the incandescent lamp. In 1887 his time was
comparatively free, and the phonograph was then taken up with renewed
energy, and the effort made to overcome its mechanical defects and to
furnish a commercial instrument, so that its early promise might be realized.
The important changes made from that time up to 1890 converted the
phonograph from a scientific toy into a successful industrial apparatus. The
idea of forming the record on tinfoil had been early abandoned, and in its
stead was substituted a cylinder of wax-like material, in which the record
was cut by a minute chisel-like gouging tool. Such a record or phonogram,
as it was then called, could be removed from the machine or replaced at any
time, many reproductions could be obtained without wearing out the record,
and whenever desired the record could be shaved off by a turning-tool so as
to present a fresh surface on which a new record could be formed,
something like an ancient palimpsest. A wax cylinder having walls less than
one-quarter of an inch in thickness could be used for receiving a large
number of records, since the maximum depth of the record groove is hardly
ever greater than one one-thousandth of an inch. Later on, and as the
crowning achievement in the phonograph field, from a commercial point of
view, came the duplication of records to the extent of many thousands from
a single "master." This work was actively developed between the years

a single "master." This work was actively developed between the years
Page 153
1890 and 1898, and its difficulties may be appreciated when the problem is
stated; the copying from a single master of many millions of excessively
minute sound-waves having a maximum width of one hundredth of an inch,
and a maximum depth of one thousandth of an inch, or less than the
thickness of a sheet of tissue-paper. Among the interesting developments of
this process was the coating of the original or master record with a
homogeneous film of gold so thin that three hundred thousand of these
piled one on top of the other would present a thickness of only one inch!
Another important change was in the nature of a reversal of the original
arrangement, the cylinder or mandrel carrying the record being mounted in
fixed bearings, and the recording or reproducing device being fed
lengthwise, like the cutting-tool of a lathe, as the blank or record was
rotated. It was early recognized that a single needle for forming the record
and the reproduction therefrom was an undesirable arrangement, since the
formation of the record required a very sharp cutting-tool, while satisfactory
and repeated reproduction suggested the use of a stylus which would result
in the minimum wear. After many experiments and the production of a
number of types of machines, the present recorders and reproducers were
evolved, the former consisting of a very small cylindrical gouging tool
having a diameter of about forty thousandths of an inch, and the latter a ball
or button-shaped stylus with a diameter of about thirty-five thousandths of
an inch. By using an incisor of this sort, the record is formed of a series of
connected gouges with rounded sides, varying in depth and width, and with
which the reproducer automatically engages and maintains its engagement.
Another difficulty encountered in the commercial development of the
phonograph was the adjustment of the recording stylus so as to enter the
wax-like surface to a very slight depth, and of the reproducer so as to
engage exactly the record when formed. The earlier types of machines were
provided with separate screws for effecting these adjustments; but
considerable skill was required to obtain good results, and great difficulty
was experienced in meeting the variations in the wax-like cylinders, due to
the warping under atmospheric changes. Consequently, with the early types
of commercial phonographs, it was first necessary to shave off the blank
accurately before a record was formed thereon, in order that an absolutely
true surface might be presented. To overcome these troubles, the very
ingenious suggestion was then made and adopted, of connecting the
recording and reproducing styluses to their respective diaphragms through

the instrumentality of a compensating weight, which acted practically as a
fixed support under the very rapid sound vibrations, but which yielded
readily to distortions or variations in the wax-like cylinders. By reason of
this improvement, it became possible to do away with all adjustments, the
mass of the compensating weight causing the recorder to engage the blank
automatically to the required depth, and to maintain the reproducing stylus
always with the desired pressure on the record when formed. These
automatic adjustments were maintained even though the blank or record
might be so much out of true as an eighth of an inch, equal to more than
two hundred times the maximum depth of the record groove.
Another improvement that followed along the lines adopted by Edison
for the commercial development of the phonograph was making the
recording and reproducing styluses of sapphire, an extremely hard, non-
oxidizable jewel, so that those tiny instruments would always retain their
true form and effectively resist wear. Of course, in this work many other
things were done that may still be found on the perfected phonograph as it
stands to-day, and many other suggestions were made which were
contemporaneously adopted, but which were later abandoned. For the
curious-minded, reference is made to the records in the Patent Office, which
will show that up to 1893 Edison had obtained upward of sixty-five patents
in this art, from which his line of thought can be very closely traced. The
phonograph of to-day, except for the perfection of its mechanical features,
in its beauty of manufacture and design, and in small details, may be
considered identical with the machine of 1889, with the exception that with
the latter the rotation of the record cylinder was effected by an electric
motor.
Its essential use as then contemplated was as a substitute for
stenographers, and the most extravagant fancies were indulged in as to
utility in that field. To exploit the device commercially, the patents were
sold to Philadelphia capitalists, who organized the North American
Phonograph Company, through which leases for limited periods were
granted to local companies doing business in special territories, generally
within the confines of a single State. Under that plan, resembling the
methods of 1878, the machines and blank cylinders were manufactured by
the Edison Phonograph Works, which still retains its factories at Orange,
New Jersey. The marketing enterprise was early doomed to failure,
principally because the instruments were not well understood, and did not

principally because the instruments were not well understood, and did not
Page 155
possess the necessary refinements that would fit them for the special field in
which they were to be used. At first the instruments were leased; but it was
found that the leases were seldom renewed. Efforts were then made to sell
them, but the prices were high—from $100 to $150. In the midst of these
difficulties, the chief promoter of the enterprise, Mr. Lippincott, died; and it
was soon found that the roseate dreams of success entertained by the
sanguine promoters were not to be realized. The North American
Phonograph Company failed, its principal creditor being Mr. Edison, who,
having acquired the assets of the defunct concern, organized the National
Phonograph Company, to which he turned over the patents; and with
characteristic energy he attempted again to build up a business with which
his favorite and, to him, most interesting invention might be successfully
identified. The National Phonograph Company from the very start
determined to retire at least temporarily from the field of stenographic use,
and to exploit the phonograph for musical purposes as a competitor of the
music-box. Hence it was necessary that for such work the relatively heavy
and expensive electric motor should be discarded, and a simple spring
motor constructed with a sufficiently sensitive governor to permit accurate
musical reproduction. Such a motor was designed, and is now used on all
phonographs except on such special instruments as may be made with
electric motors, as well as on the successful apparatus that has more
recently been designed and introduced for stenographic use. Improved
factory facilities were introduced; new tools were made, and various types
of machines were designed so that phonographs can now be bought at
prices ranging from $10 to $200. Even with the changes which were thus
made in the two machines, the work of developing the business was slow,
as a demand had to be created; and the early prejudice of the public against
the phonograph, due to its failure as a stenographic apparatus, had to be
overcome. The story of the phonograph as an industrial enterprise, from this
point of departure, is itself full of interest, but embraces so many details that
it is necessarily given in a separate later chapter. We must return to the days
of 1878, when Edison, with at least three first-class inventions to his credit
—the quadruplex, the carbon telephone, and the phonograph—had become
a man of mark and a "world character."
The invention of the phonograph was immediately followed, as usual, by
the appearance of several other incidental and auxiliary devices, some
patented, and others remaining simply the application of the principles of
which they were to be used. At first the instruments were leased; but it was

The invention of the phonograph was immediately followed, as usual, by
the appearance of several other incidental and auxiliary devices, some
patented, and others remaining simply the application of the principles of

apparatus that had been worked out. One of these was the telephonograph, a
combination of a telephone at a distant station with a phonograph. The
diaphragm of the phonograph mouthpiece is actuated by an electromagnet
in the same way as that of an ordinary telephone receiver, and in this
manner a record of the message spoken from a distance can be obtained and
turned into sound at will. Evidently such a process is reversible, and the
phonograph can send a message to the distant receiver.
This idea was brilliantly demonstrated in practice in February, 1889, by
Mr. W. J. Hammer, one of Edison's earliest and most capable associates,
who carried on telephonographic communication between New York and an
audience in Philadelphia. The record made in New York on the Edison
phonograph was repeated into an Edison carbon transmitter, sent over one
hundred and three miles of circuit, including six miles of underground
cable; received by an Edison motograph; repeated by that on to a
phonograph; transferred from the phonograph to an Edison carbon
transmitter, and by that delivered to the Edison motograph receiver in the
enthusiastic lecture-hall, where every one could hear each sound and
syllable distinctly. In real practice this spectacular playing with sound
vibrations, as if they were lacrosse balls to toss around between the goals,
could be materially simplified.
The modern megaphone, now used universally in making announcements
to large crowds, particularly at sporting events, is also due to this period as
a perfection by Edison of many antecedent devices going back, perhaps,
much further than the legendary funnels through which Alexander the Great
is said to have sent commands to his outlying forces. The improved Edison
megaphone for long-distance work comprised two horns of wood or metal
about six feet long, tapering from a diameter of two feet six inches at the
mouth to a small aperture provided with ear-tubes. These converging horns
or funnels, with a large speaking-trumpet in between them, are mounted on
a tripod, and the megaphone is complete. Conversation can be carried on
with this megaphone at a distance of over two miles, as with a ship or the
balloon. The modern megaphone now employs the receiver form thus
introduced as its very effective transmitter, with which the old-fashioned
speaking-trumpet cannot possibly compete; and the word "megaphone" is
universally applied to the single, side-flaring horn.

A further step in this line brought Edison to the "aerophone," around
which the Figaro weaved its fanciful description. In the construction of the
aerophone the same kind of tympanum is used as in the phonograph, but the
imitation of the human voice, or the transmission of sound, is effected by
the quick opening and closing of valves placed within a steam-whistle or an
organ-pipe. The vibrations of the diaphragm communicated to the valves
cause them to operate in synchronism, so that the vibrations are thrown
upon the escaping air or steam; and the result is an instrument with a
capacity of magnifying the sounds two hundred times, and of hurling them
to great distances intelligibly, like a huge fog-siren, but with immense
clearness and penetration. All this study of sound transmission over long
distances without wires led up to the consideration and invention of pioneer
apparatus for wireless telegraphy—but that also is another chapter.
Yet one more ingenious device of this period must be noted—Edison's
vocal engine, the patent application for which was executed in August,
1878, the patent being granted the following December. Reference to this
by Edison himself has already been quoted. The "voice-engine," or
"phonomotor," converts the vibrations of the voice or of music, acting on
the diaphragm, into motion which is utilized to drive some secondary
appliance, whether as a toy or for some useful purpose. Thus a man can
actually talk a hole through a board.
Somewhat weary of all this work and excitement, and not having enjoyed
any cessation from toil, or period of rest, for ten years, Edison jumped
eagerly at the opportunity afforded him in the summer of 1878 of making a
westward trip. Just thirty years later, on a similar trip over the same ground,
he jotted down for this volume some of his reminiscences. The lure of 1878
was the opportunity to try the ability of his delicate tasimeter during the
total eclipse of the sun, July 29. His admiring friend, Prof. George F.
Barker, of the University of Pennsylvania, with whom he had now been on
terms of intimacy for some years, suggested the holiday, and was himself a
member of the excursion party that made its rendezvous at Rawlins,
Wyoming Territory. Edison had tested his tasimeter, and was satisfied that it
would measure down to the millionth part of a degree Fahrenheit. It was
just ten years since he had left the West in poverty and obscurity, a
penniless operator in search of a job; but now he was a great inventor and
famous, a welcome addition to the band of astronomers and physicists
assembled to observe the eclipse and the corona.

"There were astronomers from nearly every nation," says Mr. Edison.
"We had a special car. The country at that time was rather new; game was in
great abundance, and could be seen all day long from the car window,
especially antelope. We arrived at Rawlins about 4 P.M. It had a small
machine shop, and was the point where locomotives were changed for the
next section. The hotel was a very small one, and by doubling up we were
barely accommodated. My room-mate was Fox, the correspondent of the
New York Herald. After we retired and were asleep a thundering knock on
the door awakened us. Upon opening the door a tall, handsome man with
flowing hair dressed in western style entered the room. His eyes were
bloodshot, and he was somewhat inebriated. He introduced himself as
'Texas Jack'—Joe Chromondo—and said he wanted to see Edison, as he had
read about me in the newspapers. Both Fox and I were rather scared, and
didn't know what was to be the result of the interview. The landlord
requested him not to make so much noise, and was thrown out into the hall.
Jack explained that he had just come in with a party which had been
hunting, and that he felt fine. He explained, also, that he was the boss
pistol-shot of the West; that it was he who taught the celebrated Doctor
Carver how to shoot. Then suddenly pointing to a weather-vane on the
freight depot, he pulled out a Colt revolver and fired through the window,
hitting the vane. The shot awakened all the people, and they rushed in to see
who was killed. It was only after I told him I was tired and would see him
in the morning that he left. Both Fox and I were so nervous we didn't sleep
any that night.
"We were told in the morning that Jack was a pretty good fellow, and was
not one of the 'bad men,' of whom they had a good supply. They had one in
the jail, and Fox and I went over to see him. A few days before he had held
up a Union Pacific train and robbed all the passengers. In the jail also was a
half-breed horse-thief. We interviewed the bad man through bars as big as
railroad rails. He looked like a 'bad man.' The rim of his ear all around came
to a sharp edge and was serrated. His eyes were nearly white, and appeared
as if made of glass and set in wrong, like the life-size figures of Indians in
the Smithsonian Institution. His face was also extremely irregular. He
wouldn't answer a single question. I learned afterward that he got seven
years in prison, while the horse-thief was hanged. As horses ran wild, and
there was no protection, it meant death to steal one."

hunting, and that he felt fine. He explained, also, that he was the boss
pistol-shot of the West; that it was he who taught the celebrated Doctor
Carver how to shoot. Then suddenly pointing to a weather-vane on the
freight depot, he pulled out a Colt revolver and fired through the window,
hitting the vane. The shot awakened all the people, and they rushed in to see
who was killed. It was only after I told him I was tired and would see him
in the morning that he left. Both Fox and I were so nervous we didn't sleep
any that night.
"We were told in the morning that Jack was a pretty good fellow, and was
not one of the 'bad men,' of whom they had a good supply. They had one in
the jail, and Fox and I went over to see him. A few days before he had held
up a Union Pacific train and robbed all the passengers. In the jail also was a
half-breed horse-thief. We interviewed the bad man through bars as big as
railroad rails. He looked like a 'bad man.' The rim of his ear all around came
to a sharp edge and was serrated. His eyes were nearly white, and appeared
as if made of glass and set in wrong, like the life-size figures of Indians in
the Smithsonian Institution. His face was also extremely irregular. He
wouldn't answer a single question. I learned afterward that he got seven
years in prison, while the horse-thief was hanged. As horses ran wild, and
there was no protection, it meant death to steal one."

This was one interlude among others. "The first thing the astronomers did
was to determine with precision their exact locality upon the earth. A
number of observations were made, and Watson, of Michigan University,
with two others, worked all night computing, until they agreed. They said
they were not in error more than one hundred feet, and that the station was
twelve miles out of the position given on the maps. It seemed to take an
immense amount of mathematics. I preserved one of the sheets, which
looked like the time-table of a Chinese railroad. The instruments of the
various parties were then set up in different parts of the little town, and got
ready for the eclipse which was to occur in three or four days. Two days
before the event we all got together, and obtaining an engine and car, went
twelve miles farther west to visit the United States Government
astronomers at a place called Separation, the apex of the Great Divide,
where the waters run east to the Mississippi and west to the Pacific. Fox and
I took our Winchester rifles with an idea of doing a little shooting. After
calling on the Government people we started to interview the telegraph
operator at this most lonely and desolate spot. After talking over old
acquaintances I asked him if there was any game around. He said, 'Plenty of
jack-rabbits.' These jack-rabbits are a very peculiar species. They have ears
about six inches long and very slender legs, about three times as long as
those of an ordinary rabbit, and travel at a great speed by a series of jumps,
each about thirty feet long, as near as I could judge. The local people called
them 'narrow-gauge mules.' Asking the operator the best direction, he
pointed west, and noticing a rabbit in a clear space in the sage bushes, I
said, 'There is one now.' I advanced cautiously to within one hundred feet
and shot. The rabbit paid no attention. I then advanced to within ten feet and
shot again—the rabbit was still immovable. On looking around, the whole
crowd at the station were watching—and then I knew the rabbit was
stuffed! However, we did shoot a number of live ones until Fox ran out of
cartridges. On returning to the station I passed away the time shooting at
cans set on a pile of tins. Finally the operator said to Fox: 'I have a fine
Springfield musket, suppose you try it!' So Fox took the musket and fired. It
knocked him nearly over. It seems that the musket had been run over by a
handcar, which slightly bent the long barrel, but not sufficiently for an
amateur like Fox to notice. After Fox had his shoulder treated with arnica at
the Government hospital tent, we returned to Rawlins."

The eclipse was, however, the prime consideration, and Edison followed
the example of his colleagues in making ready. The place which he secured
for setting up his tasimeter was an enclosure hardly suitable for the purpose,
and he describes the results as follows:
"I had my apparatus in a small yard enclosed by a board fence six feet
high, at one end there was a house for hens. I noticed that they all went to
roost just before totality. At the same time a slight wind arose, and at the
moment of totality the atmosphere was filled with thistle-down and other
light articles. I noticed one feather, whose weight was at least one hundred
and fifty milligrams, rise perpendicularly to the top of the fence, where it
floated away on the wind. My apparatus was entirely too sensitive, and I got
no results." It was found that the heat from the corona of the sun was ten
times the index capacity of the instrument; but this result did not leave the
value of the device in doubt. The Scientific American remarked;
"Seeing that the tasimeter is affected by a wider range of etheric
undulations than the eye can take cognizance of, and is withal far more
acutely sensitive, the probabilities are that it will open up hitherto
inaccessible regions of space, and possibly extend the range of aerial
knowledge as far beyond the limit obtained by the telescope as that is
beyond the narrow reach of unaided vision."
The eclipse over, Edison, with Professor Barker, Major Thornberg,
several soldiers, and a number of railroad officials, went hunting about one
hundred miles south of the railroad in the Ute country. A few months later
the Major and thirty soldiers were ambushed near the spot at which the
hunting-party had camped, and all were killed. Through an introduction
from Mr. Jay Gould, who then controlled the Union Pacific, Edison was
allowed to ride on the cow-catchers of the locomotives. "The different
engineers gave me a small cushion, and every day I rode in this manner,
from Omaha to the Sacramento Valley, except through the snow-shed on the
summit of the Sierras, without dust or anything else to obstruct the view.
Only once was I in danger when the locomotive struck an animal about the
size of a small cub bear—which I think was a badger. This animal struck
the front of the locomotive just under the headlight with great violence, and
was then thrown off by the rebound. I was sitting to one side grasping the
angle brace, so no harm was done."

This welcome vacation lasted nearly two months; but Edison was back in
his laboratory and hard at work before the end of August, gathering up
many loose ends, and trying out many thoughts and ideas that had
accumulated on the trip. One hot afternoon—August 30th, as shown by the
document in the case—Mr. Edison was found by one of the authors of this
biography employed most busily in making a mysterious series of tests on
paper, using for ink acids that corrugated and blistered the paper where
written upon. When interrogated as to his object, he stated that the plan was
to afford blind people the means of writing directly to each other, especially
if they were also deaf and could not hear a message on the phonograph. The
characters which he was thus forming on the paper were high enough in
relief to be legible to the delicate touch of a blind man's fingers, and with
simple apparatus letters could be thus written, sent, and read. There was
certainly no question as to the result obtained at the moment, which was all
that was asked; but the Edison autograph thus and then written now shows
the paper eaten out by the acid used, although covered with glass for many
years. Mr. Edison does not remember that he ever recurred to this very
interesting test.
He was, however, ready for anything new or novel, and no record can
ever be made or presented that would do justice to a tithe of the thoughts
and fancies daily and hourly put upon the rack. The famous note-books, to
which reference will be made later, were not begun as a regular series, as it
was only the profusion of these ideas that suggested the vital value of such
systematic registration. Then as now, the propositions brought to Edison
ranged over every conceivable subject, but the years have taught him
caution in grappling with them. He tells an amusing story of one dilemma
into which his good-nature led him at this period: "At Menlo Park one day,
a farmer came in and asked if I knew any way to kill potato-bugs. He had
twenty acres of potatoes, and the vines were being destroyed. I sent men out
and culled two quarts of bugs, and tried every chemical I had to destroy
them. Bisulphide of carbon was found to do it instantly. I got a drum and
went over to the potato farm and sprinkled it on the vines with a pot. Every
bug dropped dead. The next morning the farmer came in very excited and
reported that the stuff had killed the vines as well. I had to pay $300 for not
experimenting properly."
During this year, 1878, the phonograph made its way also to Europe, and
various sums of money were paid there to secure the rights to its

many loose ends, and trying out many thoughts and ideas that had

manufacture and exploitation. In England, for example, the Microscopic
Company paid $7500 down and agreed to a royalty, while arrangements
were effected also in France, Russia, and other countries. In every instance,
as in this country, the commercial development had to wait several years,
for in the mean time another great art had been brought into existence,
demanding exclusive attention and exhaustive toil. And when the work was
done the reward was a new heaven and a new earth—in the art of
illumination.

CHAPTER XI
THE INVENTION OF THE INCANDESCENT LAMP
IT is possible to imagine a time to come when the hours of work and rest
will once more be regulated by the sun. But the course of civilization has
been marked by an artificial lengthening of the day, and by a constant
striving after more perfect means of illumination. Why mankind should
sleep through several hours of sunlight in the morning, and stay awake
through a needless time in the evening, can probably only be attributed to
total depravity. It is certainly a most stupid, expensive, and harmful habit.
In no one thing has man shown greater fertility of invention than in lighting;
to nothing does he cling more tenaciously than to his devices for furnishing
light. Electricity to-day reigns supreme in the field of illumination, but
every other kind of artificial light that has ever been known is still in use
somewhere. Toward its light-bringers the race has assumed an attitude of
veneration, though it has forgotten, if it ever heard, the names of those who
first brightened its gloom and dissipated its darkness. If the tallow candle,
hitherto unknown, were now invented, its creator would be hailed as one of
the greatest benefactors of the present age.
Up to the close of the eighteenth century, the means of house and street
illumination were of two generic kinds—grease and oil; but then came a
swift and revolutionary change in the adoption of gas. The ideas and
methods of Murdoch and Lebon soon took definite shape, and "coal smoke"
was piped from its place of origin to distant points of consumption. As early
as 1804, the first company ever organized for gas lighting was formed in
London, one side of Pall Mall being lit up by the enthusiastic pioneer,
Winsor, in 1807. Equal activity was shown in America, and Baltimore
began the practice of gas lighting in 1816. It is true that there were
explosions, and distinguished men like Davy and Watt opined that the
illuminant was too dangerous; but the "spirit of coal" had demonstrated its
usefulness convincingly, and a commercial development began, which, for
extent and rapidity, was not inferior to that marking the concurrent adoption
of steam in industry and transportation.

Meantime the wax candle and the Argand oil lamp held their own
bravely. The whaling fleets, long after gas came into use, were one of the
greatest sources of our national wealth. To New Bedford, Massachusetts,
alone, some three or four hundred ships brought their whale and sperm oil,
spermaceti, and whalebone; and at one time that port was accounted the
richest city in the United States in proportion to its population. The ship-
owners and refiners of that whaling metropolis were slow to believe that
their monopoly could ever be threatened by newer sources of illumination;
but gas had become available in the cities, and coal-oil and petroleum were
now added to the list of illuminating materials. The American whaling fleet,
which at the time of Edison's birth mustered over seven hundred sail, had
dwindled probably to a bare tenth when he took up the problem of
illumination; and the competition of oil from the ground with oil from the
sea, and with coal-gas, had made the artificial production of light cheaper
than ever before, when up to the middle of the century it had remained one
of the heaviest items of domestic expense. Moreover, just about the time
that Edison took up incandescent lighting, water-gas was being introduced
on a large scale as a commercial illuminant that could be produced at a
much lower cost than coal-gas.
Throughout the first half of the nineteenth century the search for a
practical electric light was almost wholly in the direction of employing
methods analogous to those already familiar; in other words, obtaining the
illumination from the actual consumption of the light-giving material. In the
third quarter of the century these methods were brought to practicality, but
all may be referred back to the brilliant demonstrations of Sir Humphry
Davy at the Royal Institution, circa 1809-10, when, with the current from a
battery of two thousand cells, he produced an intense voltaic arc between
the points of consuming sticks of charcoal. For more than thirty years the
arc light remained an expensive laboratory experiment; but the coming of
the dynamo placed that illuminant on a commercial basis. The mere fact
that electrical energy from the least expensive chemical battery using up
zinc and acids costs twenty times as much as that from a dynamo—driven
by steam-engine—is in itself enough to explain why so many of the electric
arts lingered in embryo after their fundamental principles had been
discovered. Here is seen also further proof of the great truth that one
invention often waits for another.

Page 165
From 1850 onward the improvements in both the arc lamp and the
dynamo were rapid; and under the superintendence of the great Faraday, in
1858, protecting beams of intense electric light from the voltaic arc were
shed over the waters of the Straits of Dover from the beacons of South
Foreland and Dungeness. By 1878 the arc-lighting industry had sprung into
existence in so promising a manner as to engender an extraordinary fever
and furor of speculation. At the Philadelphia Centennial Exposition of 1876,
Wallace-Farmer dynamos built at Ansonia, Connecticut, were shown, with
the current from which arc lamps were there put in actual service. A year or
two later the work of Charles F. Brush and Edward Weston laid the deep
foundation of modern arc lighting in America, securing as well substantial
recognition abroad.
Thus the new era had been ushered in, but it was based altogether on the
consumption of some material—carbon—in a lamp open to the air. Every
lamp the world had ever known did this, in one way or another. Edison
himself began at that point, and his note-books show that he made various
experiments with this type of lamp at a very early stage. Indeed, his
experiments had led him so far as to anticipate in 1875 what are now known
as "flaming arcs," the exceedingly bright and generally orange or rose-
colored lights which have been introduced within the last few years, and are
now so frequently seen in streets and public places. While the arcs with
plain carbons are bluish-white, those with carbons containing calcium
fluoride have a notable golden glow.
He was convinced, however, that the greatest field of lighting lay in the
illumination of houses and other comparatively enclosed areas, to replace
the ordinary gas light, rather than in the illumination of streets and other
outdoor places by lights of great volume and brilliancy. Dismissing from his
mind quickly the commercial impossibility of using arc lights for general
indoor illumination, he arrived at the conclusion that an electric lamp giving
light by incandescence was the solution of the problem.
Edison was familiar with the numerous but impracticable and
commercially unsuccessful efforts that had been previously made by other
inventors and investigators to produce electric light by incandescence, and
at the time that he began his experiments, in 1877, almost the whole
scientific world had pronounced such an idea as impossible of fulfilment.

The leading electricians, physicists, and experts of the period had been
Page 166
studying the subject for more than a quarter of a century, and with but one
known exception had proven mathematically and by close reasoning that
the "Subdivision of the Electric Light," as it was then termed, was
practically beyond attainment. Opinions of this nature have ever been but a
stimulus to Edison when he has given deep thought to a subject, and has
become impressed with strong convictions of possibility, and in this
particular case he was satisfied that the subdivision of the electric light—or,
more correctly, the subdivision of the electric current—was not only
possible but entirely practicable.
It will have been perceived from the foregoing chapters that from the
time of boyhood, when he first began to rub against the world, his
commercial instincts were alert and predominated in almost all of the
enterprises that he set in motion. This characteristic trait had grown stronger
as he matured, having received, as it did, fresh impetus and strength from
his one lapse in the case of his first patented invention, the vote-recorder.
The lesson he then learned was to devote his inventive faculties only to
things for which there was a real, genuine demand, and that would subserve
the actual necessities of humanity; and it was probably a fortunate
circumstance that this lesson was learned at the outset of his career as an
inventor. He has never assumed to be a philosopher or "pure scientist."
In order that the reader may grasp an adequate idea of the magnitude and
importance of Edison's invention of the incandescent lamp, it will be
necessary to review briefly the "state of the art" at the time he began his
experiments on that line. After the invention of the voltaic battery, early in
the last century, experiments were made which determined that heat could
be produced by the passage of the electric current through wires of platinum
and other metals, and through pieces of carbon, as noted already, and it was,
of course, also observed that if sufficient current were passed through these
conductors they could be brought from the lower stage of redness up to the
brilliant white heat of incandescence. As early as 1845 the results of these
experiments were taken advantage of when Starr, a talented American who
died at the early age of twenty-five, suggested, in his English patent of that
year, two forms of small incandescent electric lamps, one having a burner
made from platinum foil placed under a glass cover without excluding the
air; and the other composed of a thin plate or pencil of carbon enclosed in a
Torricellian vacuum. These suggestions of young Starr were followed by
many other experimenters, whose improvements consisted principally in
known exception had proven mathematically and by close reasoning that
the "Subdivision of the Electric Light," as it was then termed, was
practically beyond attainment. Opinions of this nature have ever been but a
stimulus to Edison when he has given deep thought to a subject, and has
become impressed with strong convictions of possibility, and in this
particular case he was satisfied that the subdivision of the electric light—or,
more correctly, the subdivision of the electric current—was not only
possible but entirely practicable.
It will have been perceived from the foregoing chapters that from the
time of boyhood, when he first began to rub against the world, his
commercial instincts were alert and predominated in almost all of the
enterprises that he set in motion. This characteristic trait had grown stronger
as he matured, having received, as it did, fresh impetus and strength from
his one lapse in the case of his first patented invention, the vote-recorder.
The lesson he then learned was to devote his inventive faculties only to
things for which there was a real, genuine demand, and that would subserve
the actual necessities of humanity; and it was probably a fortunate
circumstance that this lesson was learned at the outset of his career as an
inventor. He has never assumed to be a philosopher or "pure scientist."
In order that the reader may grasp an adequate idea of the magnitude and
importance of Edison's invention of the incandescent lamp, it will be
necessary to review briefly the "state of the art" at the time he began his
experiments on that line. After the invention of the voltaic battery, early in
the last century, experiments were made which determined that heat could
be produced by the passage of the electric current through wires of platinum
and other metals, and through pieces of carbon, as noted already, and it was,
of course, also observed that if sufficient current were passed through these
conductors they could be brought from the lower stage of redness up to the
brilliant white heat of incandescence. As early as 1845 the results of these
experiments were taken advantage of when Starr, a talented American who
died at the early age of twenty-five, suggested, in his English patent of that
year, two forms of small incandescent electric lamps, one having a burner
made from platinum foil placed under a glass cover without excluding the
air; and the other composed of a thin plate or pencil of carbon enclosed in a
Torricellian vacuum. These suggestions of young Starr were followed by
many other experimenters, whose improvements consisted principally in
Page 167
devices to increase the compactness and portability of the lamp, in the
sealing of the lamp chamber to prevent the admission of air, and in means
for renewing the carbon burner when it had been consumed. Thus Roberts,
in 1852, proposed to cement the neck of the glass globe into a metallic cup,
and to provide it with a tube or stop-cock for exhaustion by means of a
hand-pump. Lodyguine, Konn, Kosloff, and Khotinsky, between 1872 and
1877, proposed various ingenious devices for perfecting the joint between
the metal base and the glass globe, and also provided their lamps with
several short carbon pencils, which were automatically brought into circuit
successively as the pencils were consumed. In 1876 or 1877, Bouliguine
proposed the employment of a long carbon pencil, a short section only of
which was in circuit at any one time and formed the burner, the lamp being
provided with a mechanism for automatically pushing other sections of the
pencil into position between the contacts to renew the burner. Sawyer and
Man proposed, in 1878, to make the bottom plate of glass instead of metal,
and provided ingenious arrangements for charging the lamp chamber with
an atmosphere of pure nitrogen gas which does not support combustion.
These lamps and many others of similar character, ingenious as they
were, failed to become of any commercial value, due, among other things,
to the brief life of the carbon burner. Even under the best conditions it was
found that the carbon members were subject to a rapid disintegration or
evaporation, which experimenters assumed was due to the disrupting action
of the electric current; and hence the conclusion that carbon contained in
itself the elements of its own destruction, and was not a suitable material for
the burner of an incandescent lamp. On the other hand, platinum, although
found to be the best of all materials for the purpose, aside from its great
expense, and not combining with oxygen at high temperatures as does
carbon, required to be brought so near the melting-point in order to give
light, that a very slight increase in the temperature resulted in its
destruction. It was assumed that the difficulty lay in the material of the
burner itself, and not in its environment.
It was not realized up to such a comparatively recent date as 1879 that
the solution of the great problem of subdivision of the electric current
would not, however, be found merely in the production of a durable
incandescent electric lamp—even if any of the lamps above referred to had
fulfilled that requirement. The other principal features necessary to
subdivide the electric current successfully were: the burning of an indefinite
sealing of the lamp chamber to prevent the admission of air, and in means
for renewing the carbon burner when it had been consumed. Thus Roberts,

Page 168
number of lights on the same circuit; each light to give a useful and
economical degree of illumination; and each light to be independent of all
the others in regard to its operation and extinguishment.
The opinions of scientific men of the period on the subject are well
represented by the two following extracts—the first, from a lecture at the
Royal United Service Institution, about February, 1879, by Mr. (Sir) W. H.
Preece, one of the most eminent electricians in England, who, after
discussing the question mathematically, said: "Hence the sub-division of the
light is an absolute ignis fatuus." The other extract is from a book written by
Paget Higgs, LL.D., D.Sc., published in London in 1879, in which he says:
"Much nonsense has been talked in relation to this subject. Some inventors
have claimed the power to 'indefinitely divide' the electric current, not
knowing or forgetting that such a statement is incompatible with the well-
proven law of conservation of energy."
"Some inventors," in the last sentence just quoted, probably—indeed, we
think undoubtedly—refers to Edison, whose earlier work in electric lighting
(1878) had been announced in this country and abroad, and who had then
stated boldly his conviction of the practicability of the subdivision of the
electrical current. The above extracts are good illustrations, however, of
scientific opinions up to the end of 1879, when Mr. Edison's epoch-making
invention rendered them entirely untenable. The eminent scientist, John
Tyndall, while not sharing these precise views, at least as late as January 17,
1879, delivered a lecture before the Royal Institution on "The Electric
Light," when, after pointing out the development of the art up to Edison's
work, and showing the apparent hopelessness of the problem, he said:
"Knowing something of the intricacy of the practical problem, I should
certainly prefer seeing it in Edison's hands to having it in mine."
The reader may have deemed this sketch of the state of the art to be a
considerable digression; but it is certainly due to the subject to present the
facts in such a manner as to show that this great invention was neither the
result of improving some process or device that was known or existing at
the time, nor due to any unforeseen lucky chance, nor the accidental result
of other experiments. On the contrary, it was the legitimate outcome of a
series of exhaustive experiments founded upon logical and original
reasoning in a mind that had the courage and hardihood to set at naught the
confirmed opinions of the world, voiced by those generally acknowledged
economical degree of illumination; and each light to be independent of all
the others in regard to its operation and extinguishment.

Page 169
to be the best exponents of the art—experiments carried on amid a storm of
jeers and derision, almost as contemptuous as if the search were for the
discovery of perpetual motion. In this we see the man foreshadowed by the
boy who, when he obtained his books on chemistry or physics, did not
accept any statement of fact or experiment therein, but worked out every
one of them himself to ascertain whether or not they were true.
Although this brings the reader up to the year 1879, one must turn back
two years and accompany Edison in his first attack on the electric-light
problem. In 1877 he sold his telephone invention (the carbon transmitter) to
the Western Union Telegraph Company, which had previously come into
possession also of his quadruplex inventions, as already related. He was still
busily engaged on the telephone, on acoustic electrical transmission,
sextuplex telegraphs, duplex telegraphs, miscellaneous carbon articles, and
other inventions of a minor nature. During the whole of the previous year
and until late in the summer of 1877, he had been working with
characteristic energy and enthusiasm on the telephone; and, in developing
this invention to a successful issue, had preferred the use of carbon and had
employed it in numerous forms, especially in the form of carbonized paper.
Eighteen hundred and seventy-seven in Edison's laboratory was a
veritable carbon year, for it was carbon in some shape or form for
interpolation in electric circuits of various kinds that occupied the thoughts
of the whole force from morning to night. It is not surprising, therefore, that
in September of that year, when Edison turned his thoughts actively toward
electric lighting by incandescence, his early experiments should be in the
line of carbon as an illuminant. His originality of method was displayed at
the very outset, for one of the first experiments was the bringing to
incandescence of a strip of carbon in the open air to ascertain merely how
much current was required. This conductor was a strip of carbonized paper
about an inch long, one-sixteenth of an inch broad, and six or seven one-
thousandths of an inch thick, the ends of which were secured to clamps that
formed the poles of a battery. The carbon was lighted up to incandescence,
and, of course, oxidized and disintegrated immediately. Within a few days
this was followed by experiments with the same kind of carbon, but in
vacuo by means of a hand-worked air-pump. This time the carbon strip
burned at incandescence for about eight minutes. Various expedients to
prevent oxidization were tried, such, for instance, as coating the carbon
jeers and derision, almost as contemptuous as if the search were for the
discovery of perpetual motion. In this we see the man foreshadowed by the
boy who, when he obtained his books on chemistry or physics, did not

Page 170
with powdered glass, which in melting would protect the carbon from the
atmosphere, but without successful results.
Edison was inclined to concur in the prevailing opinion as to the easy
destructibility of carbon, but, without actually settling the point in his mind,
he laid aside temporarily this line of experiment and entered a new field. He
had made previously some trials of platinum wire as an incandescent burner
for a lamp, but left it for a time in favor of carbon. He now turned to the use
of almost infusible metals—such as boron, ruthenium, chromium, etc.—as
separators or tiny bridges between two carbon points, the current acting so
as to bring these separators to a high degree of incandescence, at which
point they would emit a brilliant light. He also placed some of these
refractory metals directly in the circuit, bringing them to incandescence,
and used silicon in powdered form in glass tubes placed in the electric
circuit. His notes include the use of powdered silicon mixed with lime or
other very infusible non-conductors or semi-conductors. Edison's
conclusions on these substances were that, while in some respects they were
within the bounds of possibility for the subdivision of the electric current,
they did not reach the ideal that he had in mind for commercial results.
Edison's systematized attacks on the problem were two in number, the
first of which we have just related, which began in September, 1877, and
continued until about January, 1878. Contemporaneously, he and his force
of men were very busily engaged day and night on other important
enterprises and inventions. Among the latter, the phonograph may be
specially mentioned, as it was invented in the late fall of 1877. From that
time until July, 1878, his time and attention day and night were almost
completely absorbed by the excitement caused by the invention and
exhibition of the machine. In July, feeling entitled to a brief vacation after
several years of continuous labor, Edison went with the expedition to
Wyoming to observe an eclipse of the sun, and incidentally to test his
tasimeter, a delicate instrument devised by him for measuring heat
transmitted through immense distances of space. His trip has been already
described. He was absent about two months. Coming home rested and
refreshed, Mr. Edison says: "After my return from the trip to observe the
eclipse of the sun, I went with Professor Barker, Professor of Physics in the
University of Pennsylvania, and Doctor Chandler, Professor of Chemistry
in Columbia College, to see Mr. Wallace, a large manufacturer of brass in
Ansonia, Connecticut. Wallace at this time was experimenting on series arc
atmosphere, but without successful results.

Page 171
lighting. Just at that time I wanted to take up something new, and Professor
Barker suggested that I go to work and see if I could subdivide the electric
light so it could be got in small units like gas. This was not a new
suggestion, because I had made a number of experiments on electric
lighting a year before this. They had been laid aside for the phonograph. I
determined to take up the search again and continue it. On my return home I
started my usual course of collecting every kind of data about gas; bought
all the transactions of the gas-engineering societies, etc., all the back
volumes of gas journals, etc. Having obtained all the data, and investigated
gas-jet distribution in New York by actual observations, I made up my mind
that the problem of the subdivision of the electric current could be solved
and made commercial." About the end of August, 1878, he began his
second organized attack on the subdivision of the current, which was
steadily maintained until he achieved signal victory a year and two months
later.
The date of this interesting visit to Ansonia is fixed by an inscription
made by Edison on a glass goblet which he used. The legend in diamond
scratches runs: "Thomas A. Edison, September 8, 1878, made under the
electric light." Other members of the party left similar memorials, which
under the circumstances have come to be greatly prized. A number of
experiments were witnessed in arc lighting, and Edison secured a small
Wallace-Farmer dynamo for his own work, as well as a set of Wallace arc
lamps for lighting the Menlo Park laboratory. Before leaving Ansonia,
Edison remarked, significantly: "Wallace, I believe I can beat you making
electric lights. I don't think you are working in the right direction." Another
date which shows how promptly the work was resumed is October 14,
1878, when Edison filed an application for his first lighting patent:
"Improvement in Electric Lights." In after years, discussing the work of
Wallace, who was not only a great pioneer electrical manufacturer, but one
of the founders of the wire-drawing and brass-working industry, Edison
said: "Wallace was one of the earliest pioneers in electrical matters in this
country. He has done a great deal of good work, for which others have
received the credit; and the work which he did in the early days of electric
lighting others have benefited by largely, and he has been crowded to one
side and forgotten." Associated in all this work with Wallace at Ansonia was
Prof. Moses G. Farmer, famous for the introduction of the fire-alarm
system; as the discoverer of the self-exciting principle of the modern

Page 172
dynamo; as a pioneer experimenter in the electric-railway field; as a
telegraph engineer, and as a lecturer on mines and explosives to naval
classes at Newport. During 1858, Farmer, who, like Edison, was a ceaseless
investigator, had made a series of studies upon the production of light by
electricity, and had even invented an automatic regulator by which a
number of platinum lamps in multiple arc could be kept at uniform voltage
for any length of time. In July, 1859, he lit up one of the rooms of his house
at Salem, Massachusetts, every evening with such lamps, using in them
small pieces of platinum and iridium wire, which were made to incandesce
by means of current from primary batteries. Farmer was not one of the party
that memorable day in September, but his work was known through his
intimate connection with Wallace, and there is no doubt that reference was
made to it. Such work had not led very far, the "lamps" were hopelessly
short-lived, and everything was obviously experimental; but it was all
helpful and suggestive to one whose open mind refused no hint from any
quarter.
At the commencement of his new attempts, Edison returned to his
experiments with carbon as an incandescent burner for a lamp, and made a
very large number of trials, all in vacuo. Not only were the ordinary strip
paper carbons tried again, but tissue-paper coated with tar and lampblack
was rolled into thin sticks, like knitting-needles, carbonized and raised to
incandescence in vacuo. Edison also tried hard carbon, wood carbons, and
almost every conceivable variety of paper carbon in like manner. With the
best vacuum that he could then get by means of the ordinary air-pump, the
carbons would last, at the most, only from ten to fifteen minutes in a state of
incandescence. Such results were evidently not of commercial value.
Edison then turned his attention in other directions. In his earliest
consideration of the problem of subdividing the electric current, he had
decided that the only possible solution lay in the employment of a lamp
whose incandescing body should have a high resistance combined with a
small radiating surface, and be capable of being used in what is called
"multiple arc," so that each unit, or lamp, could be turned on or off without
interfering with any other unit or lamp. No other arrangement could
possibly be considered as commercially practicable.
The full significance of the three last preceding sentences will not be
obvious to laymen, as undoubtedly many of the readers of this book may

The full significance of the three last preceding sentences will not be
obvious to laymen, as undoubtedly many of the readers of this book may
Page 173
be; and now being on the threshold of the series of Edison's experiments
that led up to the basic invention, we interpolate a brief explanation, in
order that the reader may comprehend the logical reasoning and work that
in this case produced such far-reaching results.
If we consider a simple circuit in which a current is flowing, and include
in the circuit a carbon horseshoe-like conductor which it is desired to bring
to incandescence by the heat generated by the current passing through it, it
is first evident that the resistance offered to the current by the wires
themselves must be less than that offered by the burner, because, otherwise
current would be wasted as heat in the conducting wires. At the very
foundation of the electric-lighting art is the essentially commercial
consideration that one cannot spend very much for conductors, and Edison
determined that, in order to use wires of a practicable size, the voltage of
the current (i.e., its pressure or the characteristic that overcomes resistance
to its flow) should be one hundred and ten volts, which since its adoption
has been the standard. To use a lower voltage or pressure, while making the
solution of the lighting problem a simple one as we shall see, would make it
necessary to increase the size of the conducting wires to a prohibitive
extent. To increase the voltage or pressure materially, while permitting
some saving in the cost of conductors, would enormously increase the
difficulties of making a sufficiently high resistance conductor to secure light
by incandescence. This apparently remote consideration —weight of copper
used—was really the commercial key to the problem, just as the
incandescent burner was the scientific key to that problem. Before Edison's
invention incandescent lamps had been suggested as a possibility, but they
were provided with carbon rods or strips of relatively low resistance, and to
bring these to incandescence required a current of low pressure, because a
current of high voltage would pass through them so readily as not to
generate heat; and to carry a current of low pressure through wires without
loss would require wires of enormous size. [8] Having a current of
relatively high pressure to contend with, it was necessary to provide a
carbon burner which, as compared with what had previously been
suggested, should have a very great resistance. Carbon as a material,
determined after patient search, apparently offered the greatest hope, but
even with this substance the necessary high resistance could be obtained
only by making the burner of extremely small cross-section, thereby also
reducing its radiating surface. Therefore, the crucial point was the
that led up to the basic invention, we interpolate a brief explanation, in
order that the reader may comprehend the logical reasoning and work that
in this case produced such far-reaching results.
If we consider a simple circuit in which a current is flowing, and include
in the circuit a carbon horseshoe-like conductor which it is desired to bring
to incandescence by the heat generated by the current passing through it, it
is first evident that the resistance offered to the current by the wires
themselves must be less than that offered by the burner, because, otherwise
current would be wasted as heat in the conducting wires. At the very
foundation of the electric-lighting art is the essentially commercial
consideration that one cannot spend very much for conductors, and Edison
determined that, in order to use wires of a practicable size, the voltage of
the current (i.e., its pressure or the characteristic that overcomes resistance
to its flow) should be one hundred and ten volts, which since its adoption
has been the standard. To use a lower voltage or pressure, while making the
solution of the lighting problem a simple one as we shall see, would make it
necessary to increase the size of the conducting wires to a prohibitive
extent. To increase the voltage or pressure materially, while permitting
some saving in the cost of conductors, would enormously increase the
difficulties of making a sufficiently high resistance conductor to secure light
by incandescence. This apparently remote consideration —weight of copper
used—was really the commercial key to the problem, just as the
incandescent burner was the scientific key to that problem. Before Edison's
invention incandescent lamps had been suggested as a possibility, but they
were provided with carbon rods or strips of relatively low resistance, and to
bring these to incandescence required a current of low pressure, because a
current of high voltage would pass through them so readily as not to
generate heat; and to carry a current of low pressure through wires without
loss would require wires of enormous size. [8] Having a current of
relatively high pressure to contend with, it was necessary to provide a
carbon burner which, as compared with what had previously been
suggested, should have a very great resistance. Carbon as a material,
determined after patient search, apparently offered the greatest hope, but
even with this substance the necessary high resistance could be obtained
only by making the burner of extremely small cross-section, thereby also
reducing its radiating surface. Therefore, the crucial point was the
Page 174
production of a hair-like carbon filament, with a relatively great resistance
and small radiating surface, capable of withstanding mechanical shock, and
susceptible of being maintained at a temperature of over two thousand
degrees for a thousand hours or more before breaking. And this filamentary
conductor required to be supported in a vacuum chamber so perfectly
formed and constructed that during all those hours, and subjected as it is to
varying temperatures, not a particle of air should enter to disintegrate the
filament. And not only so, but the lamp after its design must not be a mere
laboratory possibility, but a practical commercial article capable of being
manufactured at low cost and in large quantities. A statement of what had to
be done in those days of actual as well as scientific electrical darkness is
quite sufficient to explain Tyndall's attitude of mind in preferring that the
problem should be in Edison's hands rather than in his own. To say that the
solution of the problem lay merely in reducing the size of the carbon burner
to a mere hair, is to state a half-truth only; but who, we ask, would have had
the temerity even to suggest that such an attenuated body could be
maintained at a white heat, without disintegration, for a thousand hours?
The solution consisted not only in that, but in the enormous mass of
patiently worked-out details—the manufacture of the filaments, their
uniform carbonization, making the globes, producing a perfect vacuum, and
countless other factors, the omission of any one of which would probably
have resulted eventually in failure.
[Footnote 8: As a practical illustration of these facts it
was calculated by Professor Barker, of the University of
Pennsylvania (after Edison had invented the incandescent
lamp), that if it should cost $100,000 for copper conductors
to supply current to Edison lamps in a given area, it would
cost about $200,000,000 for copper conductors for lighting
the same area by lamps of the earlier experimenters—such,
for instance, as the lamp invented by Konn in 1875. This
enormous difference would be accounted for by the fact that
Edison's lamp was one having a high resistance and
relatively small radiating surface, while Konn's lamp was
one having a very low resistance and large radiating
surface.]
Continuing the digression one step farther in order to explain the term
"multiple arc," it may be stated that there are two principal systems of
distributing electric current, one termed "series," and the other "multiple
arc." The two are illustrated, diagrammatically, side by side, the arrows
indicating flow of current. The series system, it will be seen, presents one
continuous path for the current. The current for the last lamp must pass
and small radiating surface, capable of withstanding mechanical shock, and
susceptible of being maintained at a temperature of over two thousand
degrees for a thousand hours or more before breaking. And this filamentary
conductor required to be supported in a vacuum chamber so perfectly
formed and constructed that during all those hours, and subjected as it is to

"multiple arc," it may be stated that there are two principal systems of
distributing electric current, one termed "series," and the other "multiple
arc." The two are illustrated, diagrammatically, side by side, the arrows
indicating flow of current. The series system, it will be seen, presents one
continuous path for the current. The current for the last lamp must pass
Page 175
through the first and all the intermediate lamps. Hence, if any one light goes
out, the continuity of the path is broken, current cannot flow, and all the
lamps are extinguished unless a loop or by-path is provided. It is quite
obvious that such a system would be commercially impracticable where
small units, similar to gas jets, were employed. On the other hand, in the
multiple-arc system, current may be considered as flowing in two parallel
conductors like the vertical sides of a ladder, the ends of which never come
together. Each lamp is placed in a separate circuit across these two
conductors, like a rung in the ladder, thus making a separate and
independent path for the current in each case. Hence, if a lamp goes out,
only that individual subdivision, or ladder step, is affected; just that one
particular path for the current is interrupted, but none of the other lamps is
interfered with. They remain lighted, each one independent of the other. The
reader will quite readily understand, therefore, that a multiple-arc system is
the only one practically commercial where electric light is to be used in
small units like those of gas or oil.
Such was the nature of the problem that confronted Edison at the outset.
There was nothing in the whole world that in any way approximated a
solution, although the most brilliant minds in the electrical art had been
assiduously working on the subject for a quarter of a century preceding. As
already seen, he came early to the conclusion that the only solution lay in
the use of a lamp of high resistance and small radiating surface, and, with
characteristic fervor and energy, he attacked the problem from this
standpoint, having absolute faith in a successful outcome. The mere fact
that even with the successful production of the electric lamp the assault on
the complete problem of commercial lighting would hardly be begun did
not deter him in the slightest. To one of Edison's enthusiastic self-
confidence the long vista of difficulties ahead—we say it in all sincerity—
must have been alluring.
After having devoted several months to experimental trials of carbon, at
the end of 1878, as already detailed, he turned his attention to the platinum
group of metals and began a series of experiments in which he used chiefly
platinum wire and iridium wire, and alloys of refractory metals in the form
of wire burners for incandescent lamps. These metals have very high
fusing-points, and were found to last longer than the carbon strips
previously used when heated up to incandescence by the electric current,
although under such conditions as were then possible they were melted by
out, the continuity of the path is broken, current cannot flow, and all the
lamps are extinguished unless a loop or by-path is provided. It is quite
obvious that such a system would be commercially impracticable where
small units, similar to gas jets, were employed. On the other hand, in the

previously used when heated up to incandescence by the electric current,
although under such conditions as were then possible they were melted by
Page 176
excess of current after they had been lighted a comparatively short time,
either in the open air or in such a vacuum as could be obtained by means of
the ordinary air-pump.
Nevertheless, Edison continued along this line of experiment with
unremitting vigor, making improvement after improvement, until about
April, 1879, he devised a means whereby platinum wire of a given length,
which would melt in the open air when giving a light equal to four candles,
would emit a light of twenty-five candle-power without fusion. This was
accomplished by introducing the platinum wire into an all-glass globe,
completely sealed and highly exhausted of air, and passing a current
through the platinum wire while the vacuum was being made. In this, which
was a new and radical invention, we see the first step toward the modern
incandescent lamp. The knowledge thus obtained that current passing
through the platinum during exhaustion would drive out occluded gases
(i.e., gases mechanically held in or upon the metal), and increase the
infusibility of the platinum, led him to aim at securing greater perfection in
the vacuum, on the theory that the higher the vacuum obtained, the higher
would be the infusibility of the platinum burner. And this fact also was of
the greatest importance in making successful the final use of carbon,
because without the subjection of the carbon to the heating effect of current
during the formation of the vacuum, the presence of occluded gases would
have been a fatal obstacle.
Continuing these experiments with most fervent zeal, taking no account
of the passage of time, with an utter disregard for meals, and but scanty
hours of sleep snatched reluctantly at odd periods of the day or night,
Edison kept his laboratory going without cessation. A great variety of lamps
was made of the platinum-iridium type, mostly with thermal devices to
regulate the temperature of the burner and prevent its being melted by an
excess of current. The study of apparatus for obtaining more perfect vacua
was unceasingly carried on, for Edison realized that in this there lay a
potent factor of ultimate success. About August he had obtained a pump that
would produce a vacuum up to about the one-hundred-thousandth part of an
atmosphere, and some time during the next month, or beginning of October,
had obtained one that would produce a vacuum up to the one-millionth part
of an atmosphere. It must be remembered that the conditions necessary for
MAINTAINING this high vacuum were only made possible by his
invention of the one-piece all-glass globe, in which all the joints were
either in the open air or in such a vacuum as could be obtained by means of
the ordinary air-pump.

invention of the one-piece all-glass globe, in which all the joints were
Page 177
hermetically sealed during its manufacture into a lamp, whereby a high
vacuum could be retained continuously for any length of time.
In obtaining this perfection of vacuum apparatus, Edison realized that he
was approaching much nearer to a solution of the problem. In his
experiments with the platinum-iridium lamps, he had been working all the
time toward the proposition of high resistance and small radiating surface,
until he had made a lamp having thirty feet of fine platinum wire wound
upon a small bobbin of infusible material; but the desired economy,
simplicity, and durability were not obtained in this manner, although at all
times the burner was maintained at a critically high temperature. After
attaining a high degree of perfection with these lamps, he recognized their
impracticable character, and his mind reverted to the opinion he had formed
in his early experiments two years before—viz., that carbon had the
requisite resistance to permit a very simple conductor to accomplish the
object if it could be used in the form of a hair-like "filament," provided the
filament itself could be made sufficiently homogeneous. As we have
already seen, he could not use carbon successfully in his earlier
experiments, for the strips of carbon he then employed, although they were
much larger than "filaments," would not stand, but were consumed in a few
minutes under the imperfect conditions then at his command.
Now, however, that he had found means for obtaining and maintaining
high vacua, Edison immediately went back to carbon, which from the first
he had conceived of as the ideal substance for a burner. His next step
proved conclusively the correctness of his old deductions. On October 21,
1879, after many patient trials, he carbonized a piece of cotton sewing-
thread bent into a loop or horseshoe form, and had it sealed into a glass
globe from which he exhausted the air until a vacuum up to one-millionth
of an atmosphere was produced. This lamp, when put on the circuit, lighted
up brightly to incandescence and maintained its integrity for over forty
hours, and lo! the practical incandescent lamp was born. The impossible, so
called, had been attained; subdivision of the electric-light current was made
practicable; the goal had been reached; and one of the greatest inventions of
the century was completed. Up to this time Edison had spent over $40,000
in his electric-light experiments, but the results far more than justified the
expenditure, for with this lamp he made the discovery that the FILAMENT
of carbon, under the conditions of high vacuum, was commercially stable
and would stand high temperatures without the disintegration and oxidation
vacuum could be retained continuously for any length of time.

that took place in all previous attempts that he knew of for making an
incandescent burner out of carbon. Besides, this lamp possessed the
characteristics of high resistance and small radiating surface, permitting
economy in the outlay for conductors, and requiring only a small current for
each unit of light—conditions that were absolutely necessary of fulfilment
in order to accomplish commercially the subdivision of the electric-light
current.
This slender, fragile, tenuous thread of brittle carbon, glowing steadily
and continuously with a soft light agreeable to the eyes, was the tiny key
that opened the door to a world revolutionized in its interior illumination. It
was a triumphant vindication of Edison's reasoning powers, his clear
perceptions, his insight into possibilities, and his inventive faculty, all of
which had already been productive of so many startling, practical, and
epoch-making inventions. And now he had stepped over the threshold of a
new art which has since become so world-wide in its application as to be an
integral part of modern human experience. [9]
[Footnote 9: The following extract from Walker on Patents
(4th edition) will probably be of interest to the reader:
"Sec. 31a. A meritorious exception, to the rule of the last
section, is involved in the adjudicated validity of the
Edison incandescent-light patent. The carbon filament, which
constitutes the only new part of the combination of the
second claim of that patent, differs from the earlier carbon
burners of Sawyer and Man, only in having a diameter of one-
sixty-fourth of an inch or less, whereas the burners of
Sawyer and Man had a diameter of one-thirty-second of an
inch or more. But that reduction of one-half in diameter
increased the resistance of the burner FOURFOLD, and reduced
its radiating surface TWOFOLD, and thus increased eightfold,
its ratio of resistance to radiating surface. That eightfold
increase of proportion enabled the resistance of the
conductor of electricity from the generator to the burner to
be increased eightfold, without any increase of percentage
of loss of energy in that conductor, or decrease of
percentage of development of heat in the burner; and thus
enabled the area of the cross-section of that conductor to
be reduced eightfold, and thus to be made with one-eighth of
the amount of copper or other metal, which would be required
if the reduction of diameter of the burner from one-thirty-
second to one-sixty-fourth of an inch had not been made. And
that great reduction in the size and cost of conductors,
involved also a great difference in the composition of the
electric energy employed in the system; that difference
consisting in generating the necessary amount of electrical

comparatively low current, instead of contrariwise. For this

No sooner had the truth of this new principle been established than the
work to establish it firmly and commercially was carried on more
assiduously than ever. The next immediate step was a further investigation
of the possibilities of improving the quality of the carbon filament. Edison
had previously made a vast number of experiments with carbonized paper
for various electrical purposes, with such good results that he once more
turned to it and now made fine filament-like loops of this material which
were put into other lamps. These proved even more successful
(commercially considered) than the carbonized thread—so much so that
after a number of such lamps had been made and put through severe tests,
the manufacture of lamps from these paper carbons was begun and carried
on continuously. This necessitated first the devising and making of a large
number of special tools for cutting the carbon filaments and for making and
putting together the various parts of the lamps. Meantime, great excitement
had been caused in this country and in Europe by the announcement of
Edison's success. In the Old World, scientists generally still declared the
impossibility of subdividing the electric-light current, and in the public
press Mr. Edison was denounced as a dreamer. Other names of a less
complimentary nature were applied to him, even though his lamp were
actually in use, and the principle of commercial incandescent lighting had
been established.
Between October 21, 1879, and December 21, 1879, some hundreds of
these paper-carbon lamps had been made and put into actual use, not only in
the laboratory, but in the streets and several residences at Menlo Park, New
Jersey, causing great excitement and bringing many visitors from far and
near. On the latter date a full-page article appeared in the New York Herald
which so intensified the excited feeling that Mr. Edison deemed it advisable
to make a public exhibition. On New Year's Eve, 1879, special trains were
run to Menlo Park by the Pennsylvania Railroad, and over three thousand
persons took advantage of the opportunity to go out there and witness this
demonstration for themselves. In this great crowd were many public

officials and men of prominence in all walks of life, who were enthusiastic
in their praises.
In the mean time, the mind that conceived and made practical this
invention could not rest content with anything less than perfection, so far as
it could be realized. Edison was not satisfied with paper carbons. They were
not fully up to the ideal that he had in mind. What he sought was a perfectly
uniform and homogeneous carbon, one like the "One-Hoss Shay," that had
no weak spots to break down at inopportune times. He began to carbonize
everything in nature that he could lay hands on. In his laboratory note-
books are innumerable jottings of the things that were carbonized and tried,
such as tissue-paper, soft paper, all kinds of cardboards, drawing-paper of
all grades, paper saturated with tar, all kinds of threads, fish-line, threads
rubbed with tarred lampblack, fine threads plaited together in strands,
cotton soaked in boiling tar, lamp-wick, twine, tar and lampblack mixed
with a proportion of lime, vulcanized fibre, celluloid, boxwood, cocoanut
hair and shell, spruce, hickory, baywood, cedar and maple shavings,
rosewood, punk, cork, bagging, flax, and a host of other things. He also
extended his searches far into the realms of nature in the line of grasses,
plants, canes, and similar products, and in these experiments at that time
and later he carbonized, made into lamps, and tested no fewer than six
thousand different species of vegetable growths.
The reasons for such prodigious research are not apparent on the face of
the subject, nor is this the occasion to enter into an explanation, as that
alone would be sufficient to fill a fair-sized book. Suffice it to say that
Edison's omnivorous reading, keen observation, power of assimilating facts
and natural phenomena, and skill in applying the knowledge thus attained to
whatever was in hand, now came into full play in determining that the
results he desired could only be obtained in certain directions.
At this time he was investigating everything with a microscope, and one
day in the early part of 1880 he noticed upon a table in the laboratory an
ordinary palm-leaf fan. He picked it up and, looking it over, observed that it
had a binding rim made of bamboo, cut from the outer edge of the cane; a
very long strip. He examined this, and then gave it to one of his assistants,
telling him to cut it up and get out of it all the filaments he could, carbonize
them, put them into lamps, and try them. The results of this trial were
exceedingly successful, far better than with anything else thus far used;
in their praises.

invention could not rest content with anything less than perfection, so far as
it could be realized. Edison was not satisfied with paper carbons. They were

Page 181
indeed, so much so, that after further experiments and microscopic
examinations Edison was convinced that he was now on the right track for
making a thoroughly stable, commercial lamp; and shortly afterward he sent
a man to Japan to procure further supplies of bamboo. The fascinating story
of the bamboo hunt will be told later; but even this bamboo lamp was only
one item of a complete system to be devised—a system that has since
completely revolutionized the art of interior illumination.
Reference has been made in this chapter to the preliminary study that
Edison brought to bear on the development of the gas art and industry. This
study was so exhaustive that one can only compare it to the careful
investigation made in advance by any competent war staff of the elements
of strength and weakness, on both sides, in a possible campaign. A popular
idea of Edison that dies hard, pictures a breezy, slap-dash, energetic
inventor arriving at new results by luck and intuition, making boastful
assertions and then winning out by mere chance. The native simplicity of
the man, the absence of pose and ceremony, do much to strengthen this
notion; but the real truth is that while gifted with unusual imagination,
Edison's march to the goal of a new invention is positively humdrum and
monotonous in its steady progress. No one ever saw Edison in a hurry; no
one ever saw him lazy; and that which he did with slow, careful scrutiny six
months ago, he will be doing with just as much calm deliberation of
research six months hence—and six years hence if necessary. If, for
instance, he were asked to find the most perfect pebble on the Atlantic shore
of New Jersey, instead of hunting here, there, and everywhere for the
desired object, we would no doubt find him patiently screening the entire
beach, sifting out the most perfect stones and eventually, by gradual
exclusion, reaching the long-sought-for pebble; and the mere fact that in
this search years might be taken, would not lessen his enthusiasm to the
slightest extent.
In the "prospectus book" among the series of famous note-books, all the
references and data apply to gas. The book is numbered 184, falls into the
period now dealt with, and runs along casually with items spread out over
two or three years. All these notes refer specifically to "Electricity vs. Gas
as General Illuminants," and cover an astounding range of inquiry and
comment. One of the very first notes tells the whole story: "Object, Edison
to effect exact imitation of all done by gas, so as to replace lighting by gas

A large programme, but fully executed! The notes, it will be understood, are
all in Edison's handwriting. They go on to observe that "a general system of
distribution is the only possible means of economical illumination," and
they dismiss isolated-plant lighting as in mills and factories as of so little
importance to the public—"we shall leave the consideration of this out of
this book." The shrewd prophecy is made that gas will be manufactured less
for lighting, as the result of electrical competition, and more and more for
heating, etc., thus enlarging its market and increasing its income. Comment
is made on kerosene and its cost, and all kinds of general statistics are jotted

city—the effect of this on investment."
It is pointed out that "Previous inventions failed—necessities for

not to make a large light or a blinding light, but a small light having the
mildness of gas." Curves are then called for of iron and copper investment

curves on motors; graphic representation of the consumption of gas January

increased economy by larger engine, higher power, etc. There is not much
that is dilettante about all this. Note is made of an article in April, 1879,
putting the total amount of gas investment in the whole world at that time at
$1,500,000,000; which is now (1910) about the amount of the electric-
lighting investment in the United States. Incidentally a note remarks: "So

CHAPTER XII
MEMORIES OF MENLO PARK
FROM the spring of 1876 to 1886 Edison lived and did his work at
Menlo Park; and at this stage of the narrative, midway in that interesting
and eventful period, it is appropriate to offer a few notes and jottings on the
place itself, around which tradition is already weaving its fancies, just as at
the time the outpouring of new inventions from it invested the name with
sudden prominence and with the glamour of romance. "In 1876 I moved,"
says Edison, "to Menlo Park, New Jersey, on the Pennsylvania Railroad,
several miles below Elizabeth. The move was due to trouble I had about
rent. I had rented a small shop in Newark, on the top floor of a padlock
factory, by the month. I gave notice that I would give it up at the end of the
month, paid the rent, moved out, and delivered the keys. Shortly afterward I
was served with a paper, probably a judgment, wherein I was to pay nine
months' rent. There was some law, it seems, that made a monthly renter
liable for a year. This seemed so unjust that I determined to get out of a
place that permitted such injustice." For several Sundays he walked through
different parts of New Jersey with two of his assistants before he decided on
Menlo Park. The change was a fortunate one, for the inventor had married
Miss Mary E. Stillwell, and was now able to establish himself comfortably
with his wife and family while enjoying immediate access to the new
laboratory. Every moment thus saved was valuable.
To-day the place and region have gone back to the insignificance from
which Edison's genius lifted them so startlingly. A glance from the car
windows reveals only a gently rolling landscape dotted with modest
residences and unpretentious barns; and there is nothing in sight by way of
memorial to suggest that for nearly a decade this spot was the scene of the
most concentrated and fruitful inventive activity the world has ever known.
Close to the Menlo Park railway station is a group of gaunt and deserted
buildings, shelter of the casual tramp, and slowly crumbling away when not
destroyed by the carelessness of some ragged smoker. This silent group of
buildings comprises the famous old laboratory and workshops of Mr.

To-day the place and region have gone back to the insignificance from

Close to the Menlo Park railway station is a group of gaunt and deserted
buildings, shelter of the casual tramp, and slowly crumbling away when not
destroyed by the carelessness of some ragged smoker. This silent group of
buildings comprises the famous old laboratory and workshops of Mr.
Page 185
Edison, historic as being the birthplace of the carbon transmitter, the
phonograph, the incandescent lamp, and the spot where Edison also worked
out his systems of electrical distribution, his commercial dynamo, his
electric railway, his megaphone, his tasimeter, and many other inventions of
greater or lesser degree. Here he continued, moreover, his earlier work on
the quadruplex, sextuplex, multiplex, and automatic telegraphs, and did his
notable pioneer work in wireless telegraphy. As the reader knows, it had
been a master passion with Edison from boyhood up to possess a laboratory,
in which with free use of his own time and powers, and with command of
abundant material resources, he could wrestle with Nature and probe her
closest secrets. Thus, from the little cellar at Port Huron, from the scant
shelves in a baggage car, from the nooks and corners of dingy telegraph
offices, and the grimy little shops in New York and Newark, he had now
come to the proud ownership of an establishment to which his favorite word
"laboratory" might justly be applied. Here he could experiment to his heart's
content and invent on a larger, bolder scale than ever—and he did!
Menlo Park was the merest hamlet. Omitting the laboratory structures, it
had only about seven houses, the best looking of which Edison lived in, a
place that had a windmill pumping water into a reservoir. One of the stories
of the day was that Edison had his front gate so connected with the
pumping plant that every visitor as he opened or closed the gate added
involuntarily to the supply in the reservoir. Two or three of the houses were
occupied by the families of members of the staff; in the others boarders
were taken, the laboratory, of course, furnishing all the patrons. Near the
railway station was a small saloon kept by an old Scotchman named Davis,
where billiards were played in idle moments, and where in the long winter
evenings the hot stove was a centre of attraction to loungers and story-
tellers. The truth is that there was very little social life of any kind possible
under the strenuous conditions prevailing at the laboratory, where, if
anywhere, relaxation was enjoyed at odd intervals of fatigue and waiting.
The main laboratory was a spacious wooden building of two floors. The
office was in this building at first, until removed to the brick library when
that was finished. There S. L. Griffin, an old telegraph friend of Edison,
acted as his secretary and had charge of a voluminous and amazing
correspondence. The office employees were the Carman brothers and the
late John F. Randolph, afterwards secretary. According to Mr. Francis Jehl,
of Budapest, then one of the staff, to whom the writers are indebted for a
phonograph, the incandescent lamp, and the spot where Edison also worked

of Budapest, then one of the staff, to whom the writers are indebted for a
Page 186
great deal of valuable data on this period: "It was on the upper story of this
laboratory that the most important experiments were executed, and where
the incandescent lamp was born. This floor consisted of a large hall
containing several long tables, upon which could be found all the various
instruments, scientific and chemical apparatus that the arts at that time
could produce. Books lay promiscuously about, while here and there long
lines of bichromate-of-potash cells could be seen, together with
experimental models of ideas that Edison or his assistants were engaged
upon. The side walls of this hall were lined with shelves filled with bottles,
phials, and other receptacles containing every imaginable chemical and
other material that could be obtained, while at the end of this hall, and near
the organ which stood in the rear, was a large glass case containing the
world's most precious metals in sheet and wire form, together with very rare
and costly chemicals. When evening came on, and the last rays of the
setting sun penetrated through the side windows, this hall looked like a
veritable Faust laboratory.
"On the ground floor we had our testing-table, which stood on two large
pillars of brick built deep into the earth in order to get rid of all vibrations
on account of the sensitive instruments that were upon it. There was the
Thomson reflecting mirror galvanometer and electrometer, while nearby
were the standard cells by which the galvanometers were adjusted and
standardized. This testing-table was connected by means of wires with all
parts of the laboratory and machine-shop, so that measurements could be
conveniently made from a distance, as in those days we had no portable and
direct-reading instruments, such as now exist. Opposite this table we
installed, later on, our photometrical chamber, which was constructed on the
Bunsen principle. A little way from this table, and separated by a partition,
we had the chemical laboratory with its furnaces and stink-chambers. Later
on another chemical laboratory was installed near the photometer-room, and
this Dr. A. Haid had charge of."
Next to the laboratory in importance was the machine-shop, a large and
well-lighted building of brick, at one end of which there was the boiler and
engine-room. This shop contained light and heavy lathes, boring and
drilling machines, all kinds of planing machines; in fact, tools of all
descriptions, so that any apparatus, however delicate or heavy, could be
made and built as might be required by Edison in experimenting. Mr. John

Kruesi had charge of this shop, and was assisted by a number of skilled
Page 187
mechanics, notably John Ott, whose deft fingers and quick intuitive grasp of
the master's ideas are still in demand under the more recent conditions at the
Llewellyn Park laboratory in Orange.
Between the machine-shop and the laboratory was a small building of
wood used as a carpenter-shop, where Tom Logan plied his art. Nearby was
the gasoline plant. Before the incandescent lamp was perfected, the only
illumination was from gasoline gas; and that was used later for
incandescent-lamp glass-blowing, which was done in another small
building on one side of the laboratory. Apparently little or no lighting
service was obtained from the Wallace-Farmer arc lamps secured from
Ansonia, Connecticut. The dynamo was probably needed for Edison's own
experiments.
On the outskirts of the property was a small building in which lampblack
was crudely but carefully manufactured and pressed into very small cakes,
for use in the Edison carbon transmitters of that time. The night-watchman,
Alfred Swanson, took care of this curious plant, which consisted of a
battery of petroleum lamps that were forced to burn to the sooting point.
During his rounds in the night Swanson would find time to collect from the
chimneys the soot that the lamps gave. It was then weighed out into very
small portions, which were pressed into cakes or buttons by means of a
hand-press. These little cakes were delicately packed away between layers
of cotton in small, light boxes and shipped to Bergmann in New York, by
whom the telephone transmitters were being made. A little later the Edison
electric railway was built on the confines of the property out through the
woods, at first only a third of a mile in length, but reaching ultimately to
Pumptown, almost three miles away.
Mr. Edison's own words may be quoted as to the men with whom he
surrounded himself here and upon whose services he depended principally
for help in the accomplishment of his aims. In an autobiographical article in
the Electrical World of March 5, 1904, he says: "It is interesting to note that
in addition to those mentioned above (Charles Batchelor and Frank Upton),
I had around me other men who ever since have remained active in the
field, such as Messrs. Francis Jehl, William J. Hammer, Martin Force,
Ludwig K. Boehm, not forgetting that good friend and co-worker, the late
John Kruesi. They found plenty to do in the various developments of the
art, and as I now look back I sometimes wonder how we did so much in so
the master's ideas are still in demand under the more recent conditions at the
Llewellyn Park laboratory in Orange.

chimneys the soot that the lamps gave. It was then weighed out into very
small portions, which were pressed into cakes or buttons by means of a
hand-press. These little cakes were delicately packed away between layers
of cotton in small, light boxes and shipped to Bergmann in New York, by
whom the telephone transmitters were being made. A little later the Edison
electric railway was built on the confines of the property out through the
woods, at first only a third of a mile in length, but reaching ultimately to
Pumptown, almost three miles away.
Mr. Edison's own words may be quoted as to the men with whom he
surrounded himself here and upon whose services he depended principally
for help in the accomplishment of his aims. In an autobiographical article in
the Electrical World of March 5, 1904, he says: "It is interesting to note that
in addition to those mentioned above (Charles Batchelor and Frank Upton),
I had around me other men who ever since have remained active in the
field, such as Messrs. Francis Jehl, William J. Hammer, Martin Force,
Ludwig K. Boehm, not forgetting that good friend and co-worker, the late
John Kruesi. They found plenty to do in the various developments of the
art, and as I now look back I sometimes wonder how we did so much in so
Page 188
short a time." Mr. Jehl in his reminiscences adds another name to the above
—namely, that of John W. Lawson, and then goes on to say: "These are the
names of the pioneers of incandescent lighting, who were continuously at
the side of Edison day and night for some years, and who, under his
guidance, worked upon the carbon-filament lamp from its birth to ripe
maturity. These men all had complete faith in his ability and stood by him
as on a rock, guarding their work with the secretiveness of a burglar-proof
safe. Whenever it leaked out in the world that Edison was succeeding in his
work on the electric light, spies and others came to the Park; so it was of the
utmost importance that the experiments and their results should be kept a
secret until Edison had secured the protection of the Patent Office." With
this staff was associated from the first Mr. E. H. Johnson, whose work with
Mr. Edison lay chiefly, however, outside the laboratory, taking him to all
parts of the country and to Europe. There were also to be regarded as
detached members of it the Bergmann brothers, manufacturing for Mr.
Edison in New York, and incessantly experimenting for him. In addition
there must be included Mr. Samuel Insull, whose activities for many years
as private secretary and financial manager were devoted solely to Mr.
Edison's interests, with Menlo Park as a centre and main source of anxiety
as to pay-rolls and other constantly recurring obligations. The names of yet
other associates occur from time to time in this narrative—"Edison men"
who have been very proud of their close relationship to the inventor and his
work at old Menlo. "There was also Mr. Charles L. Clarke, who devoted
himself mainly to engineering matters, and later on acted as chief engineer
of the Edison Electric Light Company for some years. Then there were
William Holzer and James Hipple, both of whom took an active part in the
practical development of the glass-blowing department of the laboratory,
and, subsequently, at the first Edison lamp factory at Menlo Park. Later on
Messrs. Jehl, Hipple, and Force assisted Mr. Batchelor to install the lamp-
works of the French Edison Company at Ivry-sur-Seine. Then there were
Messrs. Charles T. Hughes, Samuel D. Mott, and Charles T. Mott, who
devoted their time chiefly to commercial affairs. Mr. Hughes conducted
most of this work, and later on took a prominent part in Edison's electric-
railway experiments. His business ability was on a high level, while his
personal character endeared him to us all."
Among other now well-known men who came to us and assisted in
various kinds of work were Messrs. Acheson, Worth, Crosby, Herrick, and
—namely, that of John W. Lawson, and then goes on to say: "These are the

Among other now well-known men who came to us and assisted in
various kinds of work were Messrs. Acheson, Worth, Crosby, Herrick, and
Page 189
Hill, while Doctor Haid was placed by Mr. Edison in charge of a special
chemical laboratory. Dr. E. L. Nichols was also with us for a short time
conducting a special series of experiments. There was also Mr. Isaacs, who
did a great deal of photographic work, and to whom we must be thankful
for the pictures of Menlo Park in connection with Edison's work.
"Among others who were added to Mr. Kruesi's staff in the machine-shop
were Messrs. J. H. Vail and W. S. Andrews. Mr. Vail had charge of the
dynamo-room. He had a good general knowledge of machinery, and very
soon acquired such familiarity with the dynamos that he could skip about
among them with astonishing agility to regulate their brushes or to throw
rosin on the belts when they began to squeal. Later on he took an active part
in the affairs and installations of the Edison Light Company. Mr. Andrews
stayed on Mr. Kruesi's staff as long as the laboratory machine-shop was
kept open, after which he went into the employ of the Edison Electric Light
Company and became actively engaged in the commercial and technical
exploitation of the system. Another man who was with us at Menlo Park
was Mr. Herman Claudius, an Austrian, who at one time was employed in
connection with the State Telegraphs of his country. To him Mr. Edison
assigned the task of making a complete model of the network of conductors
for the contemplated first station in New York."
Mr. Francis R. Upton, who was early employed by Mr. Edison as his
mathematician, furnishes a pleasant, vivid picture of his chief associates
engaged on the memorable work at Menlo Park. He says: "Mr. Charles
Batchelor was Mr. Edison's principal assistant at that time. He was an
Englishman, and came to this country to set up the thread-weaving
machinery for the Clark thread-works. He was a most intelligent, patient,
competent, and loyal assistant to Mr. Edison. I remember distinctly seeing
him work many hours to mount a small filament; and his hand would be as
steady and his patience as unyielding at the end of those many hours as it
was at the beginning, in spite of repeated failures. He was a wonderful
mechanic; the control that he had of his fingers was marvellous, and his
eyesight was sharp. Mr. Batchelor's judgment and good sense were always
in evidence.
"Mr. Kruesi was the superintendent, a Swiss trained in the best Swiss
ideas of accuracy. He was a splendid mechanic with a vigorous temper, and
wonderful ability to work continuously and to get work out of men. It was
chemical laboratory. Dr. E. L. Nichols was also with us for a short time
conducting a special series of experiments. There was also Mr. Isaacs, who
did a great deal of photographic work, and to whom we must be thankful

"Mr. Kruesi was the superintendent, a Swiss trained in the best Swiss
ideas of accuracy. He was a splendid mechanic with a vigorous temper, and
wonderful ability to work continuously and to get work out of men. It was
Page 190
an ideal combination, that of Edison, Batchelor, and Kruesi. Mr. Edison
with his wonderful flow of ideas which were sharply defined in his mind, as
can be seen by any of the sketches that he made, as he evidently always
thinks in three dimensions; Mr. Kruesi, willing to take the ideas, and
capable of comprehending them, would distribute the work so as to get it
done with marvellous quickness and great accuracy. Mr. Batchelor was
always ready for any special fine experimenting or observation, and could
hold to whatever he was at as long as Mr. Edison wished; and always
brought to bear on what he was at the greatest skill."
While Edison depended upon Upton for his mathematical work, he was
wont to check it up in a very practical manner, as evidenced by the
following incident described by Mr. Jehl: "I was once with Mr. Upton
calculating some tables which he had put me on, when Mr. Edison appeared
with a glass bulb having a pear-shaped appearance in his hand. It was the
kind that we were going to use for our lamp experiments; and Mr. Edison
asked Mr. Upton to please calculate for him its cubic contents in
centimetres. Now Mr. Upton was a very able mathematician, who, after he
finished his studies at Princeton, went to Germany and got his final gloss
under that great master, Helmholtz. Whatever he did and worked on was
executed in a pure mathematical manner, and any wrangler at Oxford would
have been delighted to see him juggle with integral and differential
equations, with a dexterity that was surprising. He drew the shape of the
bulb exactly on paper, and got the equation of its lines with which he was
going to calculate its contents, when Mr. Edison again appeared and asked
him what it was. He showed Edison the work he had already done on the
subject, and told him that he would very soon finish calculating it. 'Why,'
said Edison, 'I would simply take that bulb and fill it with mercury and
weigh it; and from the weight of the mercury and its specific gravity I'll get
it in five minutes, and use less mental energy than is necessary in such a
fatiguing operation.'"
Menlo Park became ultimately the centre of Edison's business life as it
was of his inventing. After the short distasteful period during the
introduction of his lighting system, when he spent a large part of his time at
the offices at 65 Fifth Avenue, New York, or on the actual work connected
with the New York Edison installation, he settled back again in Menlo Park
altogether. Mr. Samuel Insull describes the business methods which
prevailed throughout the earlier Menlo Park days of "storm and stress," and

with the New York Edison installation, he settled back again in Menlo Park
altogether. Mr. Samuel Insull describes the business methods which
prevailed throughout the earlier Menlo Park days of "storm and stress," and
Page 191
the curious conditions with which he had to deal as private secretary: "I
never attempted to systematize Edison's business life. Edison's whole
method of work would upset the system of any office. He was just as likely
to be at work in his laboratory at midnight as midday. He cared not for the
hours of the day or the days of the week. If he was exhausted he might more
likely be asleep in the middle of the day than in the middle of the night, as
most of his work in the way of inventions was done at night. I used to run
his office on as close business methods as my experience admitted; and I
would get at him whenever it suited his convenience. Sometimes he would
not go over his mail for days at a time; but other times he would go
regularly to his office in the morning. At other times my engagements used
to be with him to go over his business affairs at Menlo Park at night, if I
was occupied in New York during the day. In fact, as a matter of
convenience I used more often to get at him at night, as it left my days free
to transact his affairs, and enabled me, probably at a midnight luncheon, to
get a few minutes of his time to look over his correspondence and get his
directions as to what I should do in some particular negotiation or matter of
finance. While it was a matter of suiting Edison's convenience as to when I
should transact business with him, it also suited my own ideas, as it enabled
me after getting through my business with him to enjoy the privilege of
watching him at his work, and to learn something about the technical side
of matters. Whatever knowledge I may have of the electric light and power
industry I feel I owe it to the tuition of Edison. He was about the most
willing tutor, and I must confess that he had to be a patient one."
Here again occurs the reference to the incessant night-work at Menlo
Park, a note that is struck in every reminiscence and in every record of the
time. But it is not to be inferred that the atmosphere of grim determination
and persistent pursuit of the new invention characteristic of this period
made life a burden to the small family of laborers associated with Edison.
Many a time during the long, weary nights of experimenting Edison would
call a halt for refreshments, which he had ordered always to be sent in when
night-work was in progress. Everything would be dropped, all present
would join in the meal, and the last good story or joke would pass around.
In his notes Mr. Jehl says: "Our lunch always ended with a cigar, and I may
mention here that although Edison was never fastidious in eating, he always
relished a good cigar, and seemed to find in it consolation and solace.... It
often happened that while we were enjoying the cigars after our midnight
never attempted to systematize Edison's business life. Edison's whole
method of work would upset the system of any office. He was just as likely

often happened that while we were enjoying the cigars after our midnight
Page 192
repast, one of the boys would start up a tune on the organ and we would all
sing together, or one of the others would give a solo. Another of the boys
had a voice that sounded like something between the ring of an old tomato
can and a pewter jug. He had one song that he would sing while we roared
with laughter. He was also great in imitating the tin-foil phonograph....
When Boehm was in good-humor he would play his zither now and then,
and amuse us by singing pretty German songs. On many of these occasions
the laboratory was the rendezvous of jolly and convivial visitors, mostly old
friends and acquaintances of Mr. Edison. Some of the office employees
would also drop in once in a while, and as everybody present was always
welcome to partake of the midnight meal, we all enjoyed these gatherings.
After a while, when we were ready to resume work, our visitors would
intimate that they were going home to bed, but we fellows could stay up
and work, and they would depart, generally singing some song like Good-
night, ladies! . . . It often happened that when Edison had been working up
to three or four o'clock in the morning, he would lie down on one of the
laboratory tables, and with nothing but a couple of books for a pillow,
would fall into a sound sleep. He said it did him more good than being in a
soft bed, which spoils a man. Some of the laboratory assistants could be
seen now and then sleeping on a table in the early morning hours. If their
snoring became objectionable to those still at work, the 'calmer' was
applied. This machine consisted of a Babbitt's soap box without a cover.
Upon it was mounted a broad ratchet-wheel with a crank, while into the
teeth of the wheel there played a stout, elastic slab of wood. The box would
be placed on the table where the snorer was sleeping and the crank turned
rapidly. The racket thus produced was something terrible, and the sleeper
would jump up as though a typhoon had struck the laboratory. The
irrepressible spirit of humor in the old days, although somewhat strenuous
at times, caused many a moment of hilarity which seemed to refresh the
boys, and enabled them to work with renewed vigor after its manifestation."
Mr. Upton remarks that often during the period of the invention of the
incandescent lamp, when under great strain and fatigue, Edison would go to
the organ and play tunes in a primitive way, and come back to crack jokes
with the staff. "But I have often felt that Mr. Edison never could
comprehend the limitations of the strength of other men, as his own
physical and mental strength have always seemed to be without limit. He
could work continuously as long as he wished, and had sleep at his
sing together, or one of the others would give a solo. Another of the boys

could work continuously as long as he wished, and had sleep at his
Page 193
command. His sleep was always instant, profound, and restful. He has told
me that he never dreamed. I have known Mr. Edison now for thirty-one
years, and feel that he has always kept his mind direct and simple, going
straight to the root of troubles. One of the peculiarities I have noticed is that
I have never known him to break into a conversation going on around him,
and ask what people were talking about. The nearest he would ever come to
it was when there had evidently been some story told, and his face would
express a desire to join in the laugh, which would immediately invite telling
the story to him."
Next to those who worked with Edison at the laboratory and were with
him constantly at Menlo Park were the visitors, some of whom were his
business associates, some of them scientific men, and some of them hero-
worshippers and curiosity-hunters. Foremost in the first category was Mr. E.
H. Johnson, who was in reality Edison's most intimate friend, and was
required for constant consultation; but whose intense activity, remarkable
grasp of electrical principles, and unusual powers of exposition, led to his
frequent detachment for long trips, including those which resulted in the
introduction of the telephone, phonograph, and electric light in England and
on the Continent. A less frequent visitor was Mr. S. Bergmann, who had all
he needed to occupy his time in experimenting and manufacturing, and
whose contemporaneous Wooster Street letter-heads advertised Edison's
inventions as being made there, Among the scientists were Prof. George F.
Barker, of Philadelphia, a big, good-natured philosopher, whose valuable
advice Edison esteemed highly. In sharp contrast to him was the earnest,
serious Rowland, of Johns Hopkins University, afterward the leading
American physicist of his day. Profs. C. F. Brackett and C. F. Young, of
Princeton University, were often received, always interested in what Edison
was doing, and proud that one of their own students, Mr. Upton, was taking
such a prominent part in the development of the work.
Soon after the success of the lighting experiments and the installation at
Menlo Park became known, Edison was besieged by persons from all parts
of the world anxious to secure rights and concessions for their respective
countries. Among these was Mr. Louis Rau, of Paris, who organized the
French Edison Company, the pioneer Edison lighting corporation in Europe,
and who, with the aid of Mr. Batchelor, established lamp-works and a
machine-shop at Ivry sur-Seine, near Paris, in 1882. It was there that Mr.
Nikola Tesla made his entree into the field of light and power, and began his
me that he never dreamed. I have known Mr. Edison now for thirty-one

Nikola Tesla made his entree into the field of light and power, and began his
Page 194
own career as an inventor; and there also Mr. Etienne Fodor, general
manager of the Hungarian General Electric Company at Budapest, received
his early training. It was he who erected at Athens the first European Edison
station on the now universal three-wire system. Another visitor from
Europe, a little later, was Mr. Emil Rathenau, the present director of the
great Allgemeine Elektricitaets Gesellschaft of Germany. He secured the
rights for the empire, and organized the Berlin Edison system, now one of
the largest in the world. Through his extraordinary energy and enterprise the
business made enormous strides, and Mr. Rathenau has become one of the
most conspicuous industrial figures in his native country. From Italy came
Professor Colombo, later a cabinet minister, with his friend Signor Buzzi, of
Milan. The rights were secured for the peninsula; Colombo and his friends
organized the Italian Edison Company, and erected at Milan the first central
station in that country. Mr. John W. Lieb, Jr., now a vice-president of the
New York Edison Company, was sent over by Mr. Edison to steer the
enterprise technically, and spent ten years in building it up, with such
brilliant success that he was later decorated as Commander of the Order of
the Crown of Italy by King Victor. Another young American enlisted into
European service was Mr. E. G. Acheson, the inventor of carborundum,
who built a number of plants in Italy and France before he returned home.
Mr. Lieb has since become President of the American Institute of Electrical

Doctor Acheson has been President of the American Electrochemical
Society.
Switzerland sent Messrs. Turrettini, Biedermann, and Thury, all
distinguished engineers, to negotiate for rights in the republic; and so it
went with regard to all the other countries of Europe, as well as those of
South America. It was a question of keeping such visitors away rather than
of inviting them to take up the exploitation of the Edison system; for what
time was not spent in personal interviews was required for the masses of
letters from every country under the sun, all making inquiries, offering
suggestions, proposing terms. Nor were the visitors merely those on
business bent. There were the lion-hunters and celebrities, of whom Sarah
Bernhardt may serve as a type. One visit of note was that paid by Lieut. G.
W. De Long, who had an earnest and protracted conversation with Edison
over the Arctic expedition he was undertaking with the aid of Mr. James
Gordon Bennett, of the New York Herald. The Jeannette was being fitted
manager of the Hungarian General Electric Company at Budapest, received
his early training. It was he who erected at Athens the first European Edison
station on the now universal three-wire system. Another visitor from
Europe, a little later, was Mr. Emil Rathenau, the present director of the
great Allgemeine Elektricitaets Gesellschaft of Germany. He secured the
rights for the empire, and organized the Berlin Edison system, now one of
the largest in the world. Through his extraordinary energy and enterprise the
business made enormous strides, and Mr. Rathenau has become one of the
most conspicuous industrial figures in his native country. From Italy came
Professor Colombo, later a cabinet minister, with his friend Signor Buzzi, of
Milan. The rights were secured for the peninsula; Colombo and his friends
organized the Italian Edison Company, and erected at Milan the first central
station in that country. Mr. John W. Lieb, Jr., now a vice-president of the
New York Edison Company, was sent over by Mr. Edison to steer the
enterprise technically, and spent ten years in building it up, with such
brilliant success that he was later decorated as Commander of the Order of
the Crown of Italy by King Victor. Another young American enlisted into
European service was Mr. E. G. Acheson, the inventor of carborundum,
who built a number of plants in Italy and France before he returned home.
Mr. Lieb has since become President of the American Institute of Electrical
Engineers and the Association of Edison Illuminating Companies, while
Doctor Acheson has been President of the American Electrochemical
Society.

over the Arctic expedition he was undertaking with the aid of Mr. James
Gordon Bennett, of the New York Herald. The Jeannette was being fitted
Page 195
out, and Edison told De Long that he would make and present him with a
small dynamo machine, some incandescent lamps, and an arc lamp. While
the little dynamo was being built all the men in the laboratory wrote their
names on the paper insulation that was wound upon the iron core of the
armature. As the Jeannette had no steam-engine on board that could be used
for the purpose, Edison designed the dynamo so that it could be worked by
man power and told Lieutenant De Long "it would keep the boys warm up
in the Arctic," when they generated current with it. The ill-fated ship never
returned from her voyage, but went down in the icy waters of the North,
there to remain until some future cataclysm of nature, ten thousand years
hence, shall reveal the ship and the first marine dynamo as curious relics of
a remote civilization.
Edison also furnished De Long with a set of telephones provided with
extensible circuits, so that parties on the ice-floes could go long distances
from the ship and still keep in communication with her. So far as the writers
can ascertain this is the first example of "field telephony." Another nautical
experiment that he made at this time, suggested probably by the
requirements of the Arctic expedition, was a buoy that was floated in New
York harbor, and which contained a small Edison dynamo and two or three
incandescent lamps. The dynamo was driven by the wave or tide motion
through intermediate mechanism, and thus the lamps were lit up from time
to time, serving as signals. These were the prototypes of the lighted buoys
which have since become familiar, as in the channel off Sandy Hook.
One notable afternoon was that on which the New York board of
aldermen took a special train out to Menlo Park to see the lighting system
with its conductors underground in operation. The Edison Electric
Illuminating Company was applying for a franchise, and the aldermen, for
lack of scientific training and specific practical information, were very
sceptical on the subject—as indeed they might well be. "Mr. Edison
demonstrated personally the details and merits of the system to them. The
voltage was increased to a higher pressure than usual, and all the
incandescent lamps at Menlo Park did their best to win the approbation of
the New York City fathers. After Edison had finished exhibiting all the good
points of his system, he conducted his guests upstairs in the laboratory,
where a long table was spread with the best things that one of the most
prominent New York caterers could furnish. The laboratory witnessed high
times that night, for all were in the best of humor, and many a bottle was

drained in toasting the health of Edison and the aldermen." This was one of
the extremely rare occasions on which Edison has addressed an audience;
but the stake was worth the effort. The representatives of New York could
with justice drink the health of the young inventor, whose system is one of
the greatest boons the city has ever had conferred upon it.
Among other frequent visitors was Mr, Edison's father, "one of those
amiable, patriarchal characters with a Horace Greeley beard, typical
Americans of the old school," who would sometimes come into the
laboratory with his two grandchildren, a little boy and girl called "Dash"
and "Dot." He preferred to sit and watch his brilliant son at work "with an
expression of satisfaction on his face that indicated a sense of happiness and
content that his boy, born in that distant, humble home in Ohio, had risen to
fame and brought such honor upon the name. It was, indeed, a pathetic sight
to see a father venerate his son as the elder Edison did." Not less at home
was Mr. Mackenzie, the Mt. Clemens station agent, the life of whose child
Edison had saved when a train newsboy. The old Scotchman was one of the
innocent, chartered libertines of the place, with an unlimited stock of good
jokes and stories, but seldom of any practical use. On one occasion,
however, when everything possible and impossible under the sun was being
carbonized for lamp filaments, he allowed a handful of his bushy red beard
to be taken for the purpose; and his laugh was the loudest when the Edison-
Mackenzie hair lamps were brought up to incandescence—their richness in
red rays being slyly attributed to the nature of the filamentary material!
Oddly enough, a few years later, some inventor actually took out a patent
for making incandescent lamps with carbonized hair for filaments!
Yet other visitors again haunted the place, and with the following
reminiscence of one of them, from Mr. Edison himself, this part of the
chapter must close: "At Menlo Park one cold winter night there came into
the laboratory a strange man in a most pitiful condition. He was nearly
frozen, and he asked if he might sit by the stove. In a few moments he
asked for the head man, and I was brought forward. He had a head of
abnormal size, with highly intellectual features and a very small and
emaciated body. He said he was suffering very much, and asked if I had any
morphine. As I had about everything in chemistry that could be bought, I
told him I had. He requested that I give him some, so I got the morphine
sulphate. He poured out enough to kill two men, when I told him that we
didn't keep a hotel for suicides, and he had better cut the quantity down. He

Page 197
then bared his legs and arms, and they were literally pitted with scars, due
to the use of hypodermic syringes. He said he had taken it for years, and it
required a big dose to have any effect. I let him go ahead. In a short while
he seemed like another man and began to tell stories, and there were about
fifty of us who sat around listening until morning. He was a man of great
intelligence and education. He said he was a Jew, but there was no
distinctive feature to verify this assertion. He continued to stay around until
he finished every combination of morphine with an acid that I had, probably
ten ounces all told. Then he asked if he could have strychnine. I had an
ounce of the sulphate. He took enough to kill a horse, and asserted it had as
good an effect as morphine. When this was gone, the only thing I had left
was a chunk of crude opium, perhaps two or three pounds. He chewed this
up and disappeared. I was greatly disappointed, because I would have laid
in another stock of morphine to keep him at the laboratory. About a week
afterward he was found dead in a barn at Perth Amboy."
Returning to the work itself, note of which has already been made in this
and preceding chapters, we find an interesting and unique reminiscence in
Mr. Jehl's notes of the reversion to carbon as a filament in the lamps,
following an exhibition of metallic-filament lamps given in the spring of
1879 to the men in the syndicate advancing the funds for these experiments:
"They came to Menlo Park on a late afternoon train from New York. It was
already dark when they were conducted into the machine-shop, where we
had several platinum lamps installed in series. When Edison had finished
explaining the principles and details of the lamp, he asked Kruesi to let the
dynamo machine run. It was of the Gramme type, as our first dynamo of the
Edison design was not yet finished. Edison then ordered the 'juice' to be
turned on slowly. To-day I can see those lamps rising to a cherry red, like
glowbugs, and hear Mr. Edison saying 'a little more juice,' and the lamps
began to glow. 'A little more' is the command again, and then one of the
lamps emits for an instant a light like a star in the distance, after which
there is an eruption and a puff; and the machine-shop is in total darkness.
We knew instantly which lamp had failed, and Batchelor replaced that by a
good one, having a few in reserve near by. The operation was repeated two
or three times with about the same results, after which the party went into
the library until it was time to catch the train for New York."
Such an exhibition was decidedly discouraging, and it was not a jubilant
party that returned to New York, but: "That night Edison remained in the

the library until it was time to catch the train for New York."
Such an exhibition was decidedly discouraging, and it was not a jubilant
party that returned to New York, but: "That night Edison remained in the
Page 198
laboratory meditating upon the results that the platinum lamp had given so
far. I was engaged reading a book near a table in the front, while Edison
was seated in a chair by a table near the organ. With his head turned
downward, and that conspicuous lock of hair hanging loosely on one side,
he looked like Napoleon in the celebrated picture, On the Eve of a Great
Battle. Those days were heroic ones, for he then battled against mighty
odds, and the prospects were dim and not very encouraging. In cases of
emergency Edison always possessed a keen faculty of deciding immediately
and correctly what to do; and the decision he then arrived at was
predestined to be the turning-point that led him on to ultimate success....
After that exhibition we had a house-cleaning at the laboratory, and the
metallic-filament lamps were stored away, while preparations were made
for our experiments on carbon lamps."
Thus the work went on. Menlo Park has hitherto been associated in the
public thought with the telephone, phonograph, and incandescent lamp; but
it was there, equally, that the Edison dynamo and system of distribution
were created and applied to their specific purposes. While all this study of a
possible lamp was going on, Mr. Upton was busy calculating the economy
of the "multiple arc" system, and making a great many tables to determine
what resistance a lamp should have for the best results, and at what point
the proposed general system would fall off in economy when the lamps
were of the lower resistance that was then generally assumed to be
necessary. The world at that time had not the shadow of an idea as to what
the principles of a multiple arc system should be, enabling millions of
lamps to be lighted off distributing circuits, each lamp independent of every
other; but at Menlo Park at that remote period in the seventies Mr. Edison's
mathematician was formulating the inventor's conception in clear,
instructive figures; "and the work then executed has held its own ever
since." From the beginning of his experiments on electric light, Mr. Edison
had a well-defined idea of producing not only a practicable lamp, but also a
SYSTEM of commercial electric lighting. Such a scheme involved the
creation of an entirely new art, for there was nothing on the face of the earth
from which to draw assistance or precedent, unless we except the
elementary forms of dynamos then in existence. It is true, there were
several types of machines in use for the then very limited field of arc
lighting, but they were regarded as valueless as a part of a great
comprehensive scheme which could supply everybody with light. Such
far. I was engaged reading a book near a table in the front, while Edison

Page 199
machines were confessedly inefficient, although representing the farthest
reach of a young art. A commission appointed at that time by the Franklin
Institute, and including Prof. Elihu Thomson, investigated the merits of
existing dynamos and reported as to the best of them: "The Gramme
machine is the most economical as a means of converting motive force into
electricity; it utilizes in the arc from 38 to 41 per cent. of the motive work
produced, after deduction is made for friction and the resistance of the air."
They reported also that the Brush arc lighting machine "produces in the
luminous arc useful work equivalent to 31 per cent. of the motive power
employed, or to 38 1/2 per cent. after the friction has been deducted."
Commercial possibilities could not exist in the face of such low economy as
this, and Mr. Edison realized that he would have to improve the dynamo
himself if he wanted a better machine. The scientific world at that time was
engaged in a controversy regarding the external and internal resistance of a
circuit in which a generator was situated. Discussing the subject Mr. Jehl, in
his biographical notes, says: "While this controversy raged in the scientific
papers, and criticism and confusion seemed at its height, Edison and Upton
discussed this question very thoroughly, and Edison declared he did not
intend to build up a system of distribution in which the external resistance
would be equal to the internal resistance. He said he was just about going to
do the opposite; he wanted a large external resistance and a low internal
one. He said he wanted to sell the energy outside of the station and not
waste it in the dynamo and conductors, where it brought no profits.... In
these later days, when these ideas of Edison are used as common property,
and are applied in every modern system of distribution, it is astonishing to
remember that when they were propounded they met with most vehement
antagonism from the world at large." Edison, familiar with batteries in
telegraphy, could not bring himself to believe that any substitute generator
of electrical energy could be efficient that used up half its own possible
output before doing an equal amount of outside work.
Undaunted by the dicta of contemporaneous science, Mr. Edison attacked
the dynamo problem with his accustomed vigor and thoroughness. He chose
the drum form for his armature, and experimented with different kinds of
iron. Cores were made of cast iron, others of forged iron; and still others of
sheets of iron of various thicknesses separated from each other by paper or
paint. These cores were then allowed to run in an excited field, and after a
given time their temperature was measured and noted. By such practical

given time their temperature was measured and noted. By such practical
Page 200
methods Edison found that the thin, laminated cores of sheet iron gave the
least heat, and had the least amount of wasteful eddy currents. His
experiments and ideas on magnetism at that period were far in advance of
the time. His work and tests regarding magnetism were repeated later on by
Hopkinson and Kapp, who then elucidated the whole theory mathematically
by means of formulae and constants. Before this, however, Edison had
attained these results by pioneer work, founded on his original reasoning,
and utilized them in the construction of his dynamo, thus revolutionizing
the art of building such machines.
After thorough investigation of the magnetic qualities of different kinds
of iron, Edison began to make a study of winding the cores, first
determining the electromotive force generated per turn of wire at various
speeds in fields of different intensities. He also considered various forms
and shapes for the armature, and by methodical and systematic research
obtained the data and best conditions upon which he could build his
generator. In the field magnets of his dynamo he constructed the cores and
yoke of forged iron having a very large cross-section, which was a new
thing in those days. Great attention was also paid to all the joints, which
were smoothed down so as to make a perfect magnetic contact. The Edison
dynamo, with its large masses of iron, was a vivid contrast to the then
existing types with their meagre quantities of the ferric element. Edison also
made tests on his field magnets by slowly raising the strength of the
exciting current, so that he obtained figures similar to those shown by a
magnetic curve, and in this way found where saturation commenced, and
where it was useless to expend more current on the field. If he had asked
Upton at the time to formulate the results of his work in this direction, for
publication, he would have anticipated the historic work on magnetism that
was executed by the two other investigators; Hopkinson and Kapp, later on.
The laboratory note-books of the period bear abundant evidence of the
systematic and searching nature of these experiments and investigations, in
the hundreds of pages of notes, sketches, calculations, and tables made at
the time by Edison, Upton, Batchelor, Jehl, and by others who from time to
time were intrusted with special experiments to elucidate some particular
point. Mr. Jehl says: "The experiments on armature-winding were also very
interesting. Edison had a number of small wooden cores made, at both ends
of which we inserted little brass nails, and we wound the wooden cores with
twine as if it were wire on an armature. In this way we studied armature-
least heat, and had the least amount of wasteful eddy currents. His

kind of winding. Care had to be taken that the wound core corresponded to
the direction of the current, supposing it were placed in a field and
revolved. After Edison had decided this question, Upton made drawings and
tables from which the real armatures were wound and connected to the
commutator. To a student of to-day all this seems simple, but in those days
the art of constructing dynamos was about as dark as air navigation is at
present.... Edison also improved the armature by dividing it and the
commutator into a far greater number of sections than up to that time had
been the practice. He was also the first to use mica in insulating the
commutator sections from each other."
In the mean time, during the progress of the investigations on the
dynamo, word had gone out to the world that Edison expected to invent a
generator of greater efficiency than any that existed at the time. Again he
was assailed and ridiculed by the technical press, for had not the foremost
electricians and physicists of Europe and America worked for years on the
production of dynamos and arc lamps as they then existed? Even though
this young man at Menlo Park had done some wonderful things for
telegraphy and telephony; even if he had recorded and reproduced human
speech, he had his limitations, and could not upset the settled dictum of
science that the internal resistance must equal the external resistance.
Such was the trend of public opinion at the time, but "after Mr. Kruesi
had finished the first practical dynamo, and after Mr. Upton had tested it
thoroughly and verified his figures and results several times—for he also
was surprised—Edison was able to tell the world that he had made a
generator giving an efficiency of 90 per cent." Ninety per cent. as against 40
per cent. was a mighty hit, and the world would not believe it. Criticism and
argument were again at their height, while Upton, as Edison's duellist, was
kept busy replying to private and public challenges of the fact.... "The
tremendous progress of the world in the last quarter of a century, owing to
the revolution caused by the all-conquering march of 'Heavy Current
Engineering,' is the outcome of Edison's work at Menlo Park that raised the
efficiency of the dynamo from 40 per cent. to 90 per cent."
Mr. Upton sums it all up very precisely in his remarks upon this period:
"What has now been made clear by accurate nomenclature was then very
made as to who would be the first to finish properly and correctly a certain
kind of winding. Care had to be taken that the wound core corresponded to
the direction of the current, supposing it were placed in a field and
revolved. After Edison had decided this question, Upton made drawings and

efficiency of the dynamo from 40 per cent. to 90 per cent."
Mr. Upton sums it all up very precisely in his remarks upon this period:
"What has now been made clear by accurate nomenclature was then very
Page 202
foggy in the text-books. Mr. Edison had completely grasped the effect of
subdivision of circuits, and the influence of wires leading to such
subdivisions, when it was most difficult to express what he knew in
technical language. I remember distinctly when Mr. Edison gave me the
problem of placing a motor in circuit in multiple arc with a fixed resistance;
and I had to work out the problem entirely, as I could find no prior solution.
There was nothing I could find bearing upon the counter electromotive
force of the armature, and the effect of the resistance of the armature on the
work given out by the armature. It was a wonderful experience to have
problems given me out of the intuitions of a great mind, based on enormous
experience in practical work, and applying to new lines of progress. One of
the main impressions left upon me after knowing Mr. Edison for many
years is the marvellous accuracy of his guesses. He will see the general
nature of a result long before it can be reached by mathematical calculation.
His greatness was always to be clearly seen when difficulties arose. They
always made him cheerful, and started him thinking; and very soon would
come a line of suggestions which would not end until the difficulty was met
and overcome, or found insurmountable. I have often felt that Mr. Edison
got himself purposely into trouble by premature publications and otherwise,
so that he would have a full incentive to get himself out of the trouble."
This chapter may well end with a statement from Mr. Jehl, shrewd and
observant, as a participator in all the early work of the development of the
Edison lighting system: "Those who were gathered around him in the old
Menlo Park laboratory enjoyed his confidence, and he theirs. Nor was this
confidence ever abused. He was respected with a respect which only great
men can obtain, and he never showed by any word or act that he was their
employer in a sense that would hurt the feelings, as is often the case in the
ordinary course of business life. He conversed, argued, and disputed with us
all as if he were a colleague on the same footing. It was his winning ways
and manners that attached us all so loyally to his side, and made us ever
ready with a boundless devotion to execute any request or desire." Thus
does a great magnet, run through a heap of sand and filings, exert its lines
of force and attract irresistibly to itself the iron and steel particles that are
its affinity, and having sifted them out, leaving the useless dust behind, hold
them to itself with responsive tenacity.

CHAPTER XIII
A WORLD-HUNT FOR FILAMENT MATERIAL
IN writing about the old experimenting days at Menlo Park, Mr. F. R.
Upton says: "Edison's day is twenty-four hours long, for he has always
worked whenever there was anything to do, whether day or night, and
carried a force of night workers, so that his experiments could go on
continually. If he wanted material, he always made it a principle to have it
at once, and never hesitated to use special messengers to get it. I remember
in the early days of the electric light he wanted a mercury pump for
exhausting the lamps. He sent me to Princeton to get it. I got back to
Metuchen late in the day, and had to carry the pump over to the laboratory
on my back that evening, set it up, and work all night and the next day
getting results."
This characteristic principle of obtaining desired material in the quickest
and most positive way manifested itself in the search that Edison instituted
for the best kind of bamboo for lamp filaments, immediately after the
discovery related in a preceding chapter. It is doubtful whether, in the
annals of scientific research and experiment, there is anything quite
analogous to the story of this search and the various expeditions that went
out from the Edison laboratory in 1880 and subsequent years, to scour the
earth for a material so apparently simple as a homogeneous strip of
bamboo, or other similar fibre. Prolonged and exhaustive experiment,
microscopic examination, and an intimate knowledge of the nature of wood
and plant fibres, however, had led Edison to the conclusion that bamboo or
similar fibrous filaments were more suitable than anything else then known
for commercial incandescent lamps, and he wanted the most perfect for that
purpose. Hence, the quickest way was to search the tropics until the proper
material was found.
The first emissary chosen for this purpose was the late William H.
Moore, of Rahway, New Jersey, who left New York in the summer of 1880,
bound for China and Japan, these being the countries preeminently noted
for the production of abundant species of bamboo. On arrival in the East he

Moore, of Rahway, New Jersey, who left New York in the summer of 1880,
bound for China and Japan, these being the countries preeminently noted
for the production of abundant species of bamboo. On arrival in the East he
Page 205
quickly left the cities behind and proceeded into the interior, extending his
search far into the more remote country districts, collecting specimens on
his way, and devoting much time to the study of the bamboo, and in roughly
testing the relative value of its fibre in canes of one, two, three, four, and
five year growths. Great bales of samples were sent to Edison, and after
careful tests a certain variety and growth of Japanese bamboo was
determined to be the most satisfactory material for filaments that had been
found. Mr. Moore, who was continuing his searches in that country, was
instructed to arrange for the cultivation and shipment of regular supplies of
this particular species. Arrangements to this end were accordingly made
with a Japanese farmer, who began to make immediate shipments, and who
subsequently displayed so much ingenuity in fertilizing and cross-fertilizing
that the homogeneity of the product was constantly improved. The use of
this bamboo for Edison lamp filaments was continued for many years.
Although Mr. Moore did not meet with the exciting adventures of some
subsequent explorers, he encountered numerous difficulties and novel
experiences in his many months of travel through the hinterland of Japan
and China. The attitude toward foreigners thirty years ago was not as
friendly as it has since become, but Edison, as usual, had made a happy
choice of messengers, as Mr. Moore's good nature and diplomacy attested.
These qualities, together with his persistence and perseverance and faculty
of intelligent discrimination in the matter of fibres, helped to make his
mission successful, and gave to him the honor of being the one who found
the bamboo which was adopted for use as filaments in commercial Edison
lamps.
Although Edison had satisfied himself that bamboo furnished the most
desirable material thus far discovered for incandescent-lamp filaments, he
felt that in some part of the world there might be found a natural product of
the same general character that would furnish a still more perfect and
homogeneous material. In his study of this subject, and during the
prosecution of vigorous and searching inquiries in various directions, he
learned that Mr. John C. Brauner, then residing in Brooklyn, New York, had
an expert knowledge of indigenous plants of the particular kind desired.
During the course of a geological survey which he had made for the
Brazilian Government, Mr. Brauner had examined closely the various
species of palms which grow plentifully in that country, and of them there
was one whose fibres he thought would be just what Edison wanted.

Brazilian Government, Mr. Brauner had examined closely the various
species of palms which grow plentifully in that country, and of them there
was one whose fibres he thought would be just what Edison wanted.
Page 206
Accordingly, Mr. Brauner was sent for and dispatched to Brazil in
December, 1880, to search for and send samples of this and such other
palms, fibres, grasses, and canes as, in his judgment, would be suitable for
the experiments then being carried on at Menlo Park. Landing at Para, he
crossed over into the Amazonian province, and thence proceeded through
the heart of the country, making his way by canoe on the rivers and their
tributaries, and by foot into the forests and marshes of a vast and almost
untrodden wilderness. In this manner Mr. Brauner traversed about two
thousand miles of the comparatively unknown interior of Southern Brazil,
and procured a large variety of fibrous specimens, which he shipped to
Edison a few months later. When these fibres arrived in the United States
they were carefully tested and a few of them found suitable but not superior
to the Japanese bamboo, which was then being exclusively used in the
manufacture of commercial Edison lamps.
Later on Edison sent out an expedition to explore the wilds of Cuba and
Jamaica. A two months' investigation of the latter island revealed a variety
of bamboo growths, of which a great number of specimens were obtained
and shipped to Menlo Park; but on careful test they were found inferior to
the Japanese bamboo, and hence rejected. The exploration of the glades and
swamps of Florida by three men extended over a period of five months in a
minute search for fibrous woods of the palmetto species. A great variety
was found, and over five hundred boxes of specimens were shipped to the
laboratory from time to time, but none of them tested out with entirely
satisfactory results.
The use of Japanese bamboo for carbon filaments was therefore
continued in the manufacture of lamps, although an incessant search was
maintained for a still more perfect material. The spirit of progress, so
pervasive in Edison's character, led him, however, to renew his
investigations further afield by sending out two other men to examine the
bamboo and similar growths of those parts of South America not covered
by Mr. Brauner. These two men were Frank McGowan and C. F. Hanington,
both of whom had been for nearly seven years in the employ of the Edison
Electric Light Company in New York. The former was a stocky, rugged
Irishman, possessing the native shrewdness and buoyancy of his race,
coupled with undaunted courage and determination; and the latter was a
veteran of the Civil War, with some knowledge of forest and field, acquired
as a sportsman. They left New York in September, 1887, arriving in due

Page 207
time at Para, proceeding thence twenty-three hundred miles up the Amazon
River to Iquitos. Nothing of an eventful nature occurred during this trip, but
on arrival at Iquitos the two men separated; Mr. McGowan to explore on
foot and by canoe in Peru, Ecuador, and Colombia, while Mr. Hanington
returned by the Amazon River to Para. Thence Hanington went by steamer
to Montevideo, and by similar conveyance up the River de la Plata and
through Uruguay, Argentine, and Paraguay to the southernmost part of
Brazil, collecting a large number of specimens of palms and grasses.
The adventures of Mr. McGowan, after leaving Iquitos, would fill a book
if related in detail. The object of the present narrative and the space at the
authors' disposal, however, do not permit of more than a brief mention of
his experiences. His first objective point was Quito, about five hundred
miles away, which he proposed to reach on foot and by means of canoeing
on the Napo River through a wild and comparatively unknown country
teeming with tribes of hostile natives. The dangers of the expedition were
pictured to him in glowing colors, but spurning prophecies of dire disaster,
he engaged some native Indians and a canoe and started on his explorations,
reaching Quito in eighty-seven days, after a thorough search of the country
on both sides of the Napo River. From Quito he went to Guayaquil, from
there by steamer to Buenaventura, and thence by rail, twelve miles, to
Cordova. From this point he set out on foot to explore the Cauca Valley and
the Cordilleras.
Mr. McGowan found in these regions a great variety of bamboo, small
and large, some species growing seventy-five to one hundred feet in height,
and from six to nine inches in diameter. He collected a large number of
specimens, which were subsequently sent to Orange for Edison's
examination. After about fifteen months of exploration attended by much
hardship and privation, deserted sometimes by treacherous guides, twice
laid low by fevers, occasionally in peril from Indian attacks, wild animals
and poisonous serpents, tormented by insect pests, endangered by floods,
one hundred and nineteen days without meat, ninety-eight days without
taking off his clothes, Mr. McGowan returned to America, broken in health
but having faithfully fulfilled the commission intrusted to him. The Evening
Sun, New York, obtained an interview with him at that time, and in its issue
of May 2, 1889, gave more than a page to a brief story of his interesting
adventures, and then commented editorially upon them, as follows:

"A ROMANCE OF SCIENCE"
"The narrative given elsewhere in the Evening Sun of the wanderings of
Edison's missionary of science, Mr. Frank McGowan, furnishes a new proof
that the romances of real life surpass any that the imagination can frame.
"In pursuit of a substance that should meet the requirements of the
Edison incandescent lamp, Mr. McGowan penetrated the wilderness of the
Amazon, and for a year defied its fevers, beasts, reptiles, and deadly insects
in his quest of a material so precious that jealous Nature has hidden it in her
most secret fastnesses.
"No hero of mythology or fable ever dared such dragons to rescue some
captive goddess as did this dauntless champion of civilization. Theseus, or
Siegfried, or any knight of the fairy books might envy the victories of
Edison's irresistible lieutenant.
"As a sample story of adventure, Mr. McGowan's narrative is a marvel fit
to be classed with the historic journeyings of the greatest travellers. But it
gains immensely in interest when we consider that it succeeded in its
scientific purpose. The mysterious bamboo was discovered, and large
quantities of it were procured and brought to the Wizard's laboratory, there
to suffer another wondrous change and then to light up our pleasure-haunts
and our homes with a gentle radiance."
A further, though rather sad, interest attaches to the McGowan story, for
only a short time had elapsed after his return to America when he
disappeared suddenly and mysteriously, and in spite of long-continued and
strenuous efforts to obtain some light on the subject, no clew or trace of him
was ever found. He was a favorite among the Edison "oldtimers," and his
memory is still cherished, for when some of the "boys" happen to get
together, as they occasionally do, some one is almost sure to "wonder what
became of poor 'Mac.'" He was last seen at Mouquin's famous old French
restaurant on Fulton Street, New York, where he lunched with one of the
authors of this book and the late Luther Stieringer. He sat with them for two
or three hours discussing his wonderful trip, and telling some fascinating
stories of adventure. Then the party separated at the Ann Street door of the
restaurant, after making plans to secure the narrative in more detailed form
for subsequent use—and McGowan has not been seen from that hour to
this. The trail of the explorer was more instantly lost in New York than in
the vast recesses of the Amazon swamps.

The next and last explorer whom Edison sent out in search of natural
fibres was Mr. James Ricalton, of Maplewood, New Jersey, a school-
principal, a well-known traveller, and an ardent student of natural science.
Mr. Ricalton's own story of his memorable expedition is so interesting as to
be worthy of repetition here:
"A village schoolmaster is not unaccustomed to door-rappings; for the
steps of belligerent mothers are often thitherward bent seeking redress for
conjured wrongs to their darling boobies.
"It was a bewildering moment, therefore, to the Maplewood teacher
when, in answering a rap at the door one afternoon, he found, instead of an
irate mother, a messenger from the laboratory of the world's greatest
inventor bearing a letter requesting an audience a few hours later.
"Being the teacher to whom reference is made, I am now quite willing to
confess that for the remainder of that afternoon, less than a problem in
Euclid would have been sufficient to disqualify me for the remaining
scholastic duties of the hour. I felt it, of course, to be no small honor for a
humble teacher to be called to the sanctum of Thomas A. Edison. The letter,
however, gave no intimation of the nature of the object for which I had been
invited to appear before Mr. Edison....
"When I was presented to Mr. Edison his way of setting forth the mission
he had designated for me was characteristic of how a great mind conceives
vast undertakings and commands great things in few words. At this time
Mr. Edison had discovered that the fibre of a certain bamboo afforded a
very desirable carbon for the electric lamp, and the variety of bamboo used
was a product of Japan. It was his belief that in other parts of the world
other and superior varieties might be found, and to that end he had
dispatched explorers to bamboo regions in the valleys of the great South
American rivers, where specimens were found of extraordinary quality; but
the locality in which these specimens were found was lost in the limitless
reaches of those great river-bottoms. The great necessity for more durable
carbons became a desideratum so urgent that the tireless inventor decided to
commission another explorer to search the tropical jungles of the Orient.
"This brings me then to the first meeting of Edison, when he set forth
substantially as follows, as I remember it twenty years ago, the purpose for
which he had called me from my scholastic duties. With a quizzical gleam
in his eye, he said: 'I want a man to ransack all the tropical jungles of the

principal, a well-known traveller, and an ardent student of natural science.
Mr. Ricalton's own story of his memorable expedition is so interesting as to
be worthy of repetition here:
"A village schoolmaster is not unaccustomed to door-rappings; for the
steps of belligerent mothers are often thitherward bent seeking redress for
conjured wrongs to their darling boobies.
"It was a bewildering moment, therefore, to the Maplewood teacher
when, in answering a rap at the door one afternoon, he found, instead of an
irate mother, a messenger from the laboratory of the world's greatest
inventor bearing a letter requesting an audience a few hours later.
"Being the teacher to whom reference is made, I am now quite willing to
confess that for the remainder of that afternoon, less than a problem in
Euclid would have been sufficient to disqualify me for the remaining
scholastic duties of the hour. I felt it, of course, to be no small honor for a
humble teacher to be called to the sanctum of Thomas A. Edison. The letter,

Page 210
East to find a better fibre for my lamp; I expect it to be found in the palm or
bamboo family. How would you like that job?' Suiting my reply to his love
of brevity and dispatch, I said, 'That would suit me.' 'Can you go to-
morrow?' was his next question. 'Well, Mr. Edison, I must first of all get a
leave of absence from my Board of Education, and assist the board to
secure a substitute for the time of my absence. How long will it take, Mr.
Edison?' 'How can I tell? Maybe six months, and maybe five years; no
matter how long, find it.' He continued: 'I sent a man to South America to
find what I want; he found it; but lost the place where he found it, so he
might as well never have found it at all.' Hereat I was enjoined to proceed
forthwith to court the Board of Education for a leave of absence, which I
did successfully, the board considering that a call so important and honorary
was entitled to their unqualified favor, which they generously granted.
"I reported to Mr. Edison on the following day, when he instructed me to
come to the laboratory at once to learn all the details of drawing and
carbonizing fibres, which it would be necessary to do in the Oriental
jungles. This I did, and, in the mean time, a set of suitable tools for this
purpose had been ordered to be made in the laboratory. As soon as I learned
my new trade, which I accomplished in a few days, Mr. Edison directed me
to the library of the laboratory to occupy a few days in studying the
geography of the Orient and, particularly, in drawing maps of the tributaries
of the Ganges, the Irrawaddy, and the Brahmaputra rivers, and other regions
which I expected to explore.
"It was while thus engaged that Mr. Edison came to me one day and said:
'If you will go up to the house' (his palatial home not far away) 'and look
behind the sofa in the library you will find a joint of bamboo, a specimen of
that found in South America; bring it down and make a study of it; if you
find something equal to that I will be satisfied.' At the home I was guided to
the library by an Irish servant-woman, to whom I communicated my
knowledge of the definite locality of the sample joint. She plunged her arm,
bare and herculean, behind the aforementioned sofa, and holding aloft a
section of wood, called out in a mood of discovery: 'Is that it?' Replying in
the affirmative, she added, under an impulse of innocent divination that

reviewed, I come to the point when matters of immediate departure are
discussed; and when I took occasion to mention to my chief that, on the
subject of life insurance, underwriters refuse to take any risks on an
enterprise so hazardous, Mr. Edison said that, if I did not place too high a
valuation on my person, he would take the risk himself. I replied that I was
born and bred in New York State, but now that I had become a Jersey man I
did not value myself at above fifteen hundred dollars. Edison laughed and
said that he would assume the risk, and another point was settled. The next
matter was the financing of the trip, about which Mr. Edison asked in a
tentative way about the rates to the East. I told him the expense of such a
trip could not be determined beforehand in detail, but that I had established
somewhat of a reputation for economic travel, and that I did not believe any
traveller could surpass me in that respect. He desired no further assurance in
that direction, and thereupon ordered a letter of credit made out with
authorization to order a second when the first was exhausted. Herein then
are set forth in briefest space the preliminaries of a circuit of the globe in

line across the station platform near the school at Maplewood, and from this
line I would start eastward around the world, and if good-fortune should
bring me back I would meet them from the westward at the same line. As I
had often made them 'toe the scratch,' for once they were only too well
pleased to have me toe the line for them.
"This was done, and I sailed via England and the Suez Canal to Ceylon,
that fair isle to which Sindbad the Sailor made his sixth voyage,
picturesquely referred to in history as the 'brightest gem in the British
Colonial Crown.' I knew Ceylon to be eminently tropical; I knew it to be
rich in many varieties of the bamboo family, which has been called the king
of the grasses; and in this family had I most hope of finding the desired
fibre. Weeks were spent in this paradisiacal isle. Every part was visited.
Native wood craftsmen were offered a premium on every new species
brought in, and in this way nearly a hundred species were tested, a greater

gigantic tree-grass or reed growing in clumps of from one to two hundred,
often twelve inches in diameter, and one hundred and fifty feet high, and
known as the giant bamboo (Bambusa gigantia). This giant grass stood the
highest test as a carbon, and on account of its extraordinary size and
qualities I extend it this special mention. With others who have given much
attention to this remarkable reed, I believe that in its manifold uses the
bamboo is the world's greatest dendral benefactor.
"From Ceylon I proceeded to India, touching the great peninsula first at
Cape Comorin, and continuing northward by way of Pondicherry, Madura,
and Madras; and thence to the tableland of Bangalore and the Western
Ghauts, testing many kinds of wood at every point, but particularly the
palm and bamboo families. From the range of the Western Ghauts I went to
Bombay and then north by the way of Delhi to Simla, the summer capital of
the Himalayas; thence again northward to the headwaters of the Sutlej
River, testing everywhere on my way everything likely to afford the desired
carbon.
"On returning from the mountains I followed the valleys of the Jumna
and the Ganges to Calcutta, whence I again ascended the Sub-Himalayas to
Darjeeling, where the numerous river-bottoms were sprinkled plentifully
with many varieties of bamboo, from the larger sizes to dwarfed species
covering the mountain slopes, and not longer than the grass of meadows.
Again descending to the plains I passed eastward to the Brahmaputra River,
which I ascended to the foot-hills in Assam; but finding nothing of superior
quality in all this northern region I returned to Calcutta and sailed thence to
Rangoon, in Burmah; and there, finding no samples giving more excellent
tests in the lower reaches of the Irrawaddy, I ascended that river to
Mandalay, where, through Burmese bamboo wiseacres, I gathered in from
round about and tested all that the unusually rich Burmese flora could
furnish. In Burmah the giant bamboo, as already mentioned, is found
indigenous; but beside it no superior varieties were found. Samples tested at
several points on the Malay Peninsula showed no new species, except at a
point north of Singapore, where I found a species large and heavy which
gave a test nearly equal to that of the giant bamboo in Ceylon.

that in use at the lamp factory, I decided it was unnecessary to visit these
countries or New Guinea, as my 'Eureka' had already been established, and
that I would therefore set forth over the return hemisphere, searching China
and Japan on the way. The rivers in Southern China brought down to
Canton bamboos of many species, where this wondrously utilitarian reed
enters very largely into the industrial life of that people, and not merely into
the industrial life, but even into the culinary arts, for bamboo sprouts are a
universal vegetable in China; but among all the bamboos of China I found
none of superexcellence in carbonizing qualities. Japan came next in the
succession of countries to be explored, but there the work was much
simplified, from the fact that the Tokio Museum contains a complete
classified collection of all the different species in the empire, and there
samples could be obtained and tested.
"Now the last of the important bamboo-producing countries in the globe
circuit had been done, and the 'home-lap' was in order; the broad Pacific
was spanned in fourteen days; my natal continent in six; and on the 22d of
February, on the same day, at the same hour, at the same minute, one year to
a second, 'little Maude,' a sweet maid of the school, led me across the line
which completed the circuit of the globe, and where I was greeted by the
cheers of my boys and girls. I at once reported to Mr. Edison, whose
manner of greeting my return was as characteristic of the man as his
summary and matter-of-fact manner of my dispatch. His little catechism of
curious inquiry was embraced in four small and intensely Anglo-Saxon
words—with his usual pleasant smile he extended his hand and said: 'Did
you get it?' This was surely a summing of a year's exploration not less
laconic than Caesar's review of his Gallic campaign. When I replied that I
had, but that he must be the final judge of what I had found, he said that
during my absence he had succeeded in making an artificial carbon which
was meeting the requirements satisfactorily; so well, indeed, that I believe
no practical use was ever made of the bamboo fibres thereafter.
"I have herein given a very brief resume of my search for fibre through

"Thinking persons know that blatant men never accomplish much, and
Edison's marvellous brevity of speech along with his miraculous
achievements should do much to put bores and garrulity out of fashion."
Although Edison had instituted such a costly and exhaustive search
throughout the world for the most perfect of natural fibres, he did not
necessarily feel committed for all time to the exclusive use of that material
for his lamp filaments. While these explorations were in progress, as indeed
long before, he had given much thought to the production of some artificial
compound that would embrace not only the required homogeneity, but also
many other qualifications necessary for the manufacture of an improved
type of lamp which had become desirable by reason of the rapid adoption of
his lighting system.
At the very time Mr. McGowan was making his explorations deep in
South America, and Mr. Ricalton his swift trip around the world, Edison,
after much investigation and experiment, had produced a compound which
promised better results than bamboo fibres. After some changes dictated by
experience, this artificial filament was adopted in the manufacture of lamps.
No radical change was immediately made, however, but the product of the
lamp factory was gradually changed over, during the course of a few years,
from the use of bamboo to the "squirted" filament, as the new material was
called. An artificial compound of one kind or another has indeed been
universally adopted for the purpose by all manufacturers; hence the
incandescing conductors in all carbon-filament lamps of the present day are
made in that way. The fact remains, however, that for nearly nine years all
Edison lamps (many millions in the aggregate) were made with bamboo
filaments, and many of them for several years after that, until bamboo was
finally abandoned in the early nineties, except for use in a few special types
which were so made until about the end of 1908. The last few years have
witnessed a remarkable advance in the manufacture of incandescent lamps
in the substitution of metallic filaments for those of carbon. It will be
remembered that many of the earlier experiments were based on the use of
strips of platinum; while other rare metals were the subject of casual trial.
No real success was attained in that direction, and for many years the
carbon-filament lamp reigned supreme. During the last four or five years
lamps with filaments made from tantalum and tungsten have been produced
and placed on the market with great success, and are now largely used.
Their price is still very high, however, as compared with that of the carbon

ended the historic world-hunt for natural fibres. From start to finish the
investigations and searches made by Edison himself, and carried on by
others under his direction, are remarkable not only from the fact that they
entailed a total expenditure of about $100,000, (disbursed under his
supervision by Mr. Upton), but also because of their unique inception and
thoroughness they illustrate one of the strongest traits of his character—an
invincible determination to leave no stone unturned to acquire that which he
believes to be in existence, and which, when found, will answer the purpose
that he has in mind.

CHAPTER XIV
INVENTING A COMPLETE SYSTEM OF LIGHTING
IN Berlin, on December 11, 1908, with notable eclat, the seventieth
birthday was celebrated of Emil Rathenau, the founder of the great
Allgemein Elektricitaets Gesellschaft. This distinguished German, creator
of a splendid industry, then received the congratulations of his fellow-
countrymen, headed by Emperor William, who spoke enthusiastically of his
services to electro-technics and to Germany. In his interesting
acknowledgment, Mr. Rathenau told how he went to Paris in 1881, and at
the electrical exhibition there saw the display of Edison's inventions in
electric lighting "which have met with as little proper appreciation as his
countless innovations in connection with telegraphy, telephony, and the
entire electrical industry." He saw the Edison dynamo, and he saw the
incandescent lamp, "of which millions have been manufactured since that
day without the great master being paid the tribute to his invention." But
what impressed the observant, thoroughgoing German was the breadth with
which the whole lighting art had been elaborated and perfected, even at that
early day. "The Edison system of lighting was as beautifully conceived
down to the very details, and as thoroughly worked out as if it had been
tested for decades in various towns. Neither sockets, switches, fuses, lamp-
holders, nor any of the other accessories necessary to complete the
installation were wanting; and the generating of the current, the regulation,
the wiring with distributing boxes, house connections, meters, etc., all
showed signs of astonishing skill and incomparable genius."
Such praise on such an occasion from the man who introduced
incandescent electric lighting into Germany is significant as to the
continued appreciation abroad of Mr. Edison's work. If there is one thing
modern Germany is proud and jealous of, it is her leadership in electrical
engineering and investigation. But with characteristic insight, Mr. Rathenau
here placed his finger on the great merit that has often been forgotten.
Edison was not simply the inventor of a new lamp and a new dynamo. They
were invaluable elements, but far from all that was necessary. His was the

the wiring with distributing boxes, house connections, meters, etc., all
showed signs of astonishing skill and incomparable genius."
Such praise on such an occasion from the man who introduced
incandescent electric lighting into Germany is significant as to the
continued appreciation abroad of Mr. Edison's work. If there is one thing
modern Germany is proud and jealous of, it is her leadership in electrical
engineering and investigation. But with characteristic insight, Mr. Rathenau
here placed his finger on the great merit that has often been forgotten.
Edison was not simply the inventor of a new lamp and a new dynamo. They
were invaluable elements, but far from all that was necessary. His was the
Page 217
mighty achievement of conceiving and executing in all its details an art and
an industry absolutely new to the world. Within two years this man
completed and made that art available in its essential, fundamental facts,
which remain unchanged after thirty years of rapid improvement and
widening application.
Such a stupendous feat, whose equal is far to seek anywhere in the
history of invention, is worth studying, especially as the task will take us
over much new ground and over very little of the territory already covered.
Notwithstanding the enormous amount of thought and labor expended on
the incandescent lamp problem from the autumn of 1878 to the winter of
1879, it must not be supposed for one moment that Edison's whole
endeavor and entire inventive skill had been given to the lamp alone, or the
dynamo alone. We have sat through the long watches of the night while
Edison brooded on the real solution of the swarming problems. We have
gazed anxiously at the steady fingers of the deft and cautious Batchelor, as
one fragile filament after another refused to stay intact until it could be
sealed into its crystal prison and there glow with light that never was before
on land or sea. We have calculated armatures and field coils for the new
dynamo with Upton, and held the stakes for Jehl and his fellows at their
winding bees. We have seen the mineral and vegetable kingdoms rifled and
ransacked for substances that would yield the best "filament." We have had
the vague consciousness of assisting at a great development whose
evidences to-day on every hand attest its magnitude. We have felt the fierce
play of volcanic effort, lifting new continents of opportunity from the
infertile sea, without any devastation of pre-existing fields of human toil
and harvest. But it still remains to elucidate the actual thing done; to reduce
it to concrete data, and in reducing, to unfold its colossal dimensions.
The lighting system that Edison contemplated in this entirely new
departure from antecedent methods included the generation of electrical
energy, or current, on a very large scale; its distribution throughout
extended areas, and its division and subdivision into small units converted
into light at innumerable points in every direction from the source of
supply, each unit to be independent of every other and susceptible to
immediate control by the user.
This was truly an altogether prodigious undertaking. We need not wonder
that Professor Tyndall, in words implying grave doubt as to the possibility
an industry absolutely new to the world. Within two years this man
completed and made that art available in its essential, fundamental facts,
which remain unchanged after thirty years of rapid improvement and
widening application.

This was truly an altogether prodigious undertaking. We need not wonder
that Professor Tyndall, in words implying grave doubt as to the possibility
Page 218
of any solution of the various problems, said publicly that he would much
rather have the matter in Edison's hands than in his own. There were no
precedents, nothing upon which to build or improve. The problems could
only be answered by the creation of new devices and methods expressly
worked out for their solution. An electric lamp answering certain specific
requirements would, indeed, be the key to the situation, but its commercial
adaptation required a multifarious variety of apparatus and devices. The
word "system" is much abused in invention, and during the early days of
electric lighting its use applied to a mere freakish lamp or dynamo was
often ludicrous. But, after all, nothing short of a complete system could give
real value to the lamp as an invention; nothing short of a system could body
forth the new art to the public. Let us therefore set down briefly a few of the
leading items needed for perfect illumination by electricity, all of which
were part of the Edison programme:
First—To conceive a broad and fundamentally correct method of
distributing the current, satisfactory in a scientific sense and practical
commercially in its efficiency and economy. This meant, ready made, a
comprehensive plan analogous to illumination by gas, with a network of
conductors all connected together, so that in any given city area the lights
could be fed with electricity from several directions, thus eliminating any
interruption due to the disturbance on any particular section.
Second—To devise an electric lamp that would give about the same
amount of light as a gas jet, which custom had proven to be a suitable and
useful unit. This lamp must possess the quality of requiring only a small
investment in the copper conductors reaching it. Each lamp must be
independent of every other lamp. Each and all the lights must be produced
and operated with sufficient economy to compete on a commercial basis
with gas. The lamp must be durable, capable of being easily and safely
handled by the public, and one that would remain capable of burning at full
incandescence and candle-power a great length of time.
Third—To devise means whereby the amount of electrical energy
furnished to each and every customer could be determined, as in the case of
gas, and so that this could be done cheaply and reliably by a meter at the
customer's premises.
Fourth—To elaborate a system or network of conductors capable of being
placed underground or overhead, which would allow of being tapped at any
rather have the matter in Edison's hands than in his own. There were no
precedents, nothing upon which to build or improve. The problems could
only be answered by the creation of new devices and methods expressly
worked out for their solution. An electric lamp answering certain specific
requirements would, indeed, be the key to the situation, but its commercial
adaptation required a multifarious variety of apparatus and devices. The

customer's premises.
Fourth—To elaborate a system or network of conductors capable of being
placed underground or overhead, which would allow of being tapped at any
Page 219
intervals, so that service wires could be run from the main conductors in the
street into each building. Where these mains went below the surface of the
thoroughfare, as in large cities, there must be protective conduit or pipe for
the copper conductors, and these pipes must allow of being tapped
wherever necessary. With these conductors and pipes must also be furnished
manholes, junction-boxes, connections, and a host of varied paraphernalia
insuring perfect general distribution.
Fifth—To devise means for maintaining at all points in an extended area
of distribution a practically even pressure of current, so that all the lamps,
wherever located, near or far away from the central station, should give an
equal light at all times, independent of the number that might be turned on;
and safeguarding the lamps against rupture by sudden and violent
fluctuations of current. There must also be means for thus regulating at the
point where the current was generated the quality or pressure of the current
throughout the whole lighting area, with devices for indicating what such
pressure might actually be at various points in the area.
Sixth—To design efficient dynamos, such not being in existence at the
time, that would convert economically the steam-power of high-speed
engines into electrical energy, together with means for connecting and
disconnecting them with the exterior consumption circuits; means for
regulating, equalizing their loads, and adjusting the number of dynamos to
be used according to the fluctuating demands on the central station. Also the
arrangement of complete stations with steam and electric apparatus and
auxiliary devices for insuring their efficient and continuous operation.
Seventh—To invent devices that would prevent the current from
becoming excessive upon any conductors, causing fire or other injury; also
switches for turning the current on and off; lamp-holders, fixtures, and the
like; also means and methods for establishing the interior circuits that were
to carry current to chandeliers and fixtures in buildings.
Here was the outline of the programme laid down in the autumn of 1878,
and pursued through all its difficulties to definite accomplishment in about
eighteen months, some of the steps being made immediately, others being
taken as the art evolved. It is not to be imagined for one moment that
Edison performed all the experiments with his own hands. The method of
working at Menlo Park has already been described in these pages by those
who participated. It would not only have been physically impossible for one
street into each building. Where these mains went below the surface of the
thoroughfare, as in large cities, there must be protective conduit or pipe for
the copper conductors, and these pipes must allow of being tapped
wherever necessary. With these conductors and pipes must also be furnished
manholes, junction-boxes, connections, and a host of varied paraphernalia

Edison performed all the experiments with his own hands. The method of
working at Menlo Park has already been described in these pages by those
who participated. It would not only have been physically impossible for one
Page 220
man to have done all this work himself, in view of the time and labor
required, and the endless detail; but most of the apparatus and devices
invented or suggested by him as the art took shape required the handiwork
of skilled mechanics and artisans of a high order of ability. Toward the end
of 1879 the laboratory force thus numbered at least one hundred earnest
men. In this respect of collaboration, Edison has always adopted a policy
that must in part be taken to explain his many successes. Some inventors of
the greatest ability, dealing with ideas and conceptions of importance, have
found it impossible to organize or even to tolerate a staff of co-workers,
preferring solitary and secret toil, incapable of team work, or jealous of any
intrusion that could possibly bar them from a full and complete claim to the
result when obtained. Edison always stood shoulder to shoulder with his
associates, but no one ever questioned the leadership, nor was it ever in
doubt where the inspiration originated. The real truth is that Edison has
always been so ceaselessly fertile of ideas himself, he has had more than his
whole staff could ever do to try them all out; he has sought co-operation,
but no exterior suggestion. As a matter of fact a great many of the "Edison
men" have made notable inventions of their own, with which their names
are imperishably associated; but while they were with Edison it was with
his work that they were and must be busied.
It was during this period of "inventing a system" that so much systematic
and continuous work with good results was done by Edison in the design
and perfection of dynamos. The value of his contributions to the art of
lighting comprised in this work has never been fully understood or
appreciated, having been so greatly overshadowed by his invention of the
incandescent lamp, and of a complete system of distribution. It is a fact,
however, that the principal improvements he made in dynamo-electric
generators were of a radical nature and remain in the art. Thirty years bring
about great changes, especially in a field so notably progressive as that of
the generation of electricity; but different as are the dynamos of to-day from
those of the earlier period, they embody essential principles and elements
that Edison then marked out and elaborated as the conditions of success.
There was indeed prompt appreciation in some well-informed quarters of
what Edison was doing, evidenced by the sensation caused in the summer
of 1881, when he designed, built, and shipped to Paris for the first Electrical
Exposition ever held, the largest dynamo that had been built up to that time.
It was capable of lighting twelve hundred incandescent lamps, and weighed
required, and the endless detail; but most of the apparatus and devices
invented or suggested by him as the art took shape required the handiwork
of skilled mechanics and artisans of a high order of ability. Toward the end

of 1881, when he designed, built, and shipped to Paris for the first Electrical
Exposition ever held, the largest dynamo that had been built up to that time.
It was capable of lighting twelve hundred incandescent lamps, and weighed
Page 221
with its engine twenty-seven tons, the armature alone weighing six tons. It
was then, and for a long time after, the eighth wonder of the scientific
world, and its arrival and installation in Paris were eagerly watched by the
most famous physicists and electricians of Europe.
Edison's amusing description of his experience in shipping the dynamo to
Paris when built may appropriately be given here: "I built a very large
dynamo with the engine directly connected, which I intended for the Paris
Exposition of 1881. It was one or two sizes larger than those I had
previously built. I had only a very short period in which to get it ready and
put it on a steamer to reach the Exposition in time. After the machine was
completed we found the voltage was too low. I had to devise a way of
raising the voltage without changing the machine, which I did by adding
extra magnets. After this was done, we tested the machine, and the crank-
shaft of the engine broke and flew clear across the shop. By working night
and day a new crank-shaft was put in, and we only had three days left from
that time to get it on board the steamer; and had also to run a test. So we
made arrangements with the Tammany leader, and through him with the
police, to clear the street—one of the New York crosstown streets—and line
it with policemen, as we proposed to make a quick passage, and didn't know
how much time it would take. About four hours before the steamer had to
get it, the machine was shut down after the test, and a schedule was made
out in advance of what each man had to do. Sixty men were put on top of
the dynamo to get it ready, and each man had written orders as to what he
was to perform. We got it all taken apart and put on trucks and started off.
They drove the horses with a fire-bell in front of them to the French pier,
the policemen lining the streets. Fifty men were ready to help the stevedores
get it on the steamer—and we were one hour ahead of time."
This Exposition brings us, indeed, to a dramatic and rather pathetic
parting of the ways. The hour had come for the old laboratory force that had
done such brilliant and memorable work to disband, never again to
assemble under like conditions for like effort, although its members all
remained active in the field, and many have ever since been associated
prominently with some department of electrical enterprise. The fact was
they had done their work so well they must now disperse to show the world
what it was, and assist in its industrial exploitation. In reality, they were too
few for the demands that reached Edison from all parts of the world for the
introduction of his system; and in the emergency the men nearest to him
was then, and for a long time after, the eighth wonder of the scientific
world, and its arrival and installation in Paris were eagerly watched by the
most famous physicists and electricians of Europe.

Page 222
and most trusted were those upon whom he could best depend for such
missionary work as was now required. The disciples full of fire and
enthusiasm, as well as of knowledge and experience, were soon scattered to
the four winds, and the rapidity with which the Edison system was
everywhere successfully introduced is testimony to the good judgment with
which their leader had originally selected them as his colleagues. No one
can say exactly just how this process of disintegration began, but Mr. E. H.
Johnson had already been sent to England in the Edison interests, and now
the question arose as to what should be done with the French demands and
the Paris Electrical Exposition, whose importance as a point of new
departure in electrical industry was speedily recognized on both sides of the
Atlantic. It is very interesting to note that as the earlier staff broke up,
Edison became the centre of another large body, equally devoted, but more
particularly concerned with the commercial development of his ideas. Mr.
E. G. Acheson mentions in his personal notes on work at the laboratory, that
in December of 1880, while on some experimental work, he was called to
the new lamp factory started recently at Menlo Park, and there found
Edison, Johnson, Batchelor, and Upton in conference, and "Edison
informed me that Mr. Batchelor, who was in charge of the construction,
development, and operation of the lamp factory, was soon to sail for Europe
to prepare for the exhibit to be made at the Electrical Exposition to be held
in Paris during the coming summer." These preparations overlap the
reinforcement of the staff with some notable additions, chief among them
being Mr. Samuel Insull, whose interesting narrative of events fits
admirably into the story at this stage, and gives a vivid idea of the intense
activity and excitement with which the whole atmosphere around Edison
was then surcharged: "I first met Edison on March 1, 1881. I arrived in New
York on the City of Chester about five or six in the evening, and went direct
to 65 Fifth Avenue. I had come over to act as Edison's private secretary, the
position having been obtained for me through the good offices of Mr. E. H.
Johnson, whom I had known in London, and who wrote to Mr. U. H.
Painter, of Washington, about me in the fall of 1880. Mr. Painter sent the
letter on to Mr. Batchelor, who turned it over to Edison. Johnson returned to
America late in the fall of 1880, and in January, 1881, cabled to me to come
to this country. At the time he cabled for me Edison was still at Menlo Park,
but when I arrived in New York the famous offices of the Edison Electric
Light Company had been opened at '65' Fifth Avenue, and Edison had
missionary work as was now required. The disciples full of fire and
enthusiasm, as well as of knowledge and experience, were soon scattered to
the four winds, and the rapidity with which the Edison system was

but when I arrived in New York the famous offices of the Edison Electric
Light Company had been opened at '65' Fifth Avenue, and Edison had
Page 223
moved into New York with the idea of assisting in the exploitation of the
Light Company's business.
"I was taken by Johnson direct from the Inman Steamship pier to 65 Fifth
Avenue, and met Edison for the first time. There were three rooms on the
ground floor at that time. The front one was used as a kind of reception-
room; the room immediately behind it was used as the office of the
president of the Edison Electric Light Company, Major S. B. Eaton. The
rear room, which was directly back of the front entrance hall, was Edison's
office, and there I first saw him. There was very little in the room except a
couple of walnut roller-top desks—which were very generally used in
American offices at that time. Edison received me with great cordiality. I
think he was possibly disappointed at my being so young a man; I had only
just turned twenty-one, and had a very boyish appearance. The picture of
Edison is as vivid to me now as if the incident occurred yesterday, although
it is now more than twenty-nine years since that first meeting. I had been
connected with Edison's affairs in England as private secretary to his
London agent for about two years; and had been taught by Johnson to look
on Edison as the greatest electrical inventor of the day—a view of him, by-
the-way, which has been greatly strengthened as the years have rolled by.
Owing to this, and to the fact that I felt highly flattered at the appointment
as his private secretary, I was naturally prepared to accept him as a hero.
With my strict English ideas as to the class of clothes to be worn by a
prominent man, there was nothing in Edison's dress to impress me. He wore
a rather seedy black diagonal Prince Albert coat and waistcoat, with
trousers of a dark material, and a white silk handkerchief around his neck,
tied in a careless knot falling over the stiff bosom of a white shirt somewhat
the worse for wear. He had a large wide-awake hat of the sombrero pattern
then generally used in this country, and a rough, brown overcoat, cut
somewhat similarly to his Prince Albert coat. His hair was worn quite long,
and hanging carelessly over his fine forehead. His face was at that time, as
it is now, clean shaven. He was full in face and figure, although by no
means as stout as he has grown in recent years. What struck me above
everything else was the wonderful intelligence and magnetism of his
expression, and the extreme brightness of his eyes. He was far more modest
than in my youthful picture of him. I had expected to find a man of
distinction. His appearance, as a whole, was not what you would call
'slovenly,' it is best expressed by the word 'careless.'"

Owing to this, and to the fact that I felt highly flattered at the appointment
as his private secretary, I was naturally prepared to accept him as a hero.
With my strict English ideas as to the class of clothes to be worn by a
prominent man, there was nothing in Edison's dress to impress me. He wore
a rather seedy black diagonal Prince Albert coat and waistcoat, with
trousers of a dark material, and a white silk handkerchief around his neck,
tied in a careless knot falling over the stiff bosom of a white shirt somewhat
the worse for wear. He had a large wide-awake hat of the sombrero pattern
then generally used in this country, and a rough, brown overcoat, cut
somewhat similarly to his Prince Albert coat. His hair was worn quite long,
and hanging carelessly over his fine forehead. His face was at that time, as
it is now, clean shaven. He was full in face and figure, although by no
means as stout as he has grown in recent years. What struck me above
everything else was the wonderful intelligence and magnetism of his
expression, and the extreme brightness of his eyes. He was far more modest
than in my youthful picture of him. I had expected to find a man of
distinction. His appearance, as a whole, was not what you would call
'slovenly,' it is best expressed by the word 'careless.'"

Mr. Insull supplements this pen-picture by another, bearing upon the
hustle and bustle of the moment: "After a short conversation Johnson
hurried me off to meet his family, and later in the evening, about eight
o'clock, he and I returned to Edison's office; and I found myself launched
without further ceremony into Edison's business affairs. Johnson had
already explained to me that he was sailing the next morning, March 2d, on
the S.S. Arizona, and that Mr. Edison wanted to spend the evening
discussing matters in connection with his European affairs. It was assumed,
inasmuch as I had just arrived from London, that I would be able to give
more or less information on this subject. As Johnson was to sail the next
morning at five o'clock, Edison explained that it would be necessary for him
to have an understanding of European matters. Edison started out by
drawing from his desk a check-book and stating how much money he had in
the bank; and he wanted to know what European telephone securities were
most salable, as he wished to raise the necessary funds to put on their feet
the incandescent lamp factory, the Electric Tube works, and the necessary
shops to build dynamos. All through the interview I was tremendously
impressed with Edison's wonderful resourcefulness and grasp, and his
immediate appreciation of any suggestion of consequence bearing on the
subject under discussion.
"He spoke with very great enthusiasm of the work before him—namely,
the development of his electric-lighting system; and his one idea seemed to
be to raise all the money he could with the object of pouring it into the
manufacturing side of the lighting business. I remember how
extraordinarily I was impressed with him on this account, as I had just come
from a circle of people in London who not only questioned the possibility
of the success of Edison's invention, but often expressed doubt as to
whether the work he had done could be called an invention at all. After
discussing affairs with Johnson—who was receiving his final instructions
from Edison—far into the night, and going down to the steamer to see
Johnson aboard, I finished my first night's business with Edison somewhere
between four and five in the morning, feeling thoroughly imbued with the
idea that I had met one of the great master minds of the world. You must
allow for my youthful enthusiasm, but you must also bear in mind Edison's
peculiar gift of magnetism, which has enabled him during his career to
attach so many men to him. I fell a victim to the spell at the first interview."

Events moved rapidly in those days. The next morning, Tuesday, Edison
took his new fidus Achates with him to a conference with John Roach, the
famous old ship-builder, and at it agreed to take the AEtna Iron works,
where Roach had laid the foundations of his fame and fortune. These works
were not in use at the time. They were situated on Goerck Street, New York,
north of Grand Street, on the east side of the city, and there, very soon after,
was established the first Edison dynamo-manufacturing establishment,
known for many years as the Edison Machine Works. The same night Insull
made his first visit to Menlo Park. Up to that time he had seen very little
incandescent lighting, for the simple reason that there was very little to see.
Johnson had had a few Edison lamps in London, lit up from primary
batteries, as a demonstration; and in the summer of 1880 Swan had had a
few series lamps burning in London. In New York a small gas-engine plant
was being started at the Edison offices on Fifth Avenue. But out at Menlo
Park there was the first actual electric-lighting central station, supplying
distributed incandescent lamps and some electric motors by means of
underground conductors imbedded in asphaltum and surrounded by a
wooden box. Mr. Insull says: "The system employed was naturally the two-
wire, as at that time the three-wire had not been thought of. The lamps were
partly of the horseshoe filament paper-carbon type, and partly bamboo-
filament lamps, and were of an efficiency of 95 to 100 watts per 16 c.p. I
can never forget the impression that this first view of the electric-lighting
industry produced on me. Menlo Park must always be looked upon as the
birthplace of the electric light and power industry. At that time it was the
only place where could be seen an electric light and power multiple arc
distribution system, the operation of which seemed as successful to my
youthful mind as the operation of one of the large metropolitan systems to-
day. I well remember about ten o'clock that night going down to the Menlo
Park depot and getting the station agent, who was also the telegraph
operator, to send some cable messages for me to my London friends,
announcing that I had seen Edison's incandescent lighting system in actual
operation, and that so far as I could tell it was an accomplished fact. A few
weeks afterward I received a letter from one of my London friends, who
was a doubting Thomas, upbraiding me for coming so soon under the spell
of the 'Yankee inventor.'"
It was to confront and deal with just this element of doubt in London and
in Europe generally, that the dispatch of Johnson to England and of
took his new fidus Achates with him to a conference with John Roach, the
famous old ship-builder, and at it agreed to take the AEtna Iron works,
where Roach had laid the foundations of his fame and fortune. These works

It was to confront and deal with just this element of doubt in London and
in Europe generally, that the dispatch of Johnson to England and of
Page 226
Batchelor to France was intended. Throughout the Edison staff there was a
mingled feeling of pride in the work, resentment at the doubts expressed
about it, and keen desire to show how excellent it was. Batchelor left for
Paris in July, 1881—on his second trip to Europe that year—and the exhibit
was made which brought such an instantaneous recognition of the
incalculable value of Edison's lighting inventions, as evidenced by the
awards and rewards immediately bestowed upon him. He was made an
officer of the Legion of Honor, and Prof. George F. Barker cabled as
follows from Paris, announcing the decision of the expert jury which passed
upon the exhibits: "Accept my congratulations. You have distanced all
competitors and obtained a diploma of honor, the highest award given in the
Exposition. No person in any class in which you were an exhibitor received
a like reward."
Nor was this all. Eminent men in science who had previously expressed
their disbelief in the statements made as to the Edison system were now
foremost in generous praise of his notable achievements, and accorded him
full credit for its completion. A typical instance was M. Du Moncel, a
distinguished electrician, who had written cynically about Edison's work
and denied its practicability. He now recanted publicly in this language,
which in itself shows the state of the art when Edison came to the front:
"All these experiments achieved but moderate success, and when, in 1879,
the new Edison incandescent carbon lamp was announced, many of the
scientists, and I, particularly, doubted the accuracy of the reports which
came from America. This horseshoe of carbonized paper seemed incapable
to resist mechanical shocks and to maintain incandescence for any
considerable length of time. Nevertheless, Mr. Edison was not discouraged,
and despite the active opposition made to his lamp, despite the polemic
acerbity of which he was the object, he did not cease to perfect it; and he
succeeded in producing the lamps which we now behold exhibited at the
Exposition, and are admired by all for their perfect steadiness."
The competitive lamps exhibited and tested at this time comprised those
of Edison, Maxim, Swan, and Lane-Fox. The demonstration of Edison's
success stimulated the faith of his French supporters, and rendered easier
the completion of plans for the Societe Edison Continental, of Paris, formed
to operate the Edison patents on the Continent of Europe. Mr. Batchelor,
with Messrs. Acheson and Hipple, and one or two other assistants, at the
close of the Exposition transferred their energies to the construction and

Page 227
equipment of machine-shops and lamp factories at Ivry-sur-Seine for the
company, and in a very short time the installation of plants began in various
countries—France, Italy, Holland, Belgium, etc.
All through 1881 Johnson was very busy, for his part, in England. The
first "Jumbo" Edison dynamo had gone to Paris; the second and third went
to London, where they were installed in 1881 by Mr. Johnson and his
assistant, Mr. W. J. Hammer, in the three-thousand-light central station on
Holborn Viaduct, the plant going into operation on January 12, 1882.
Outside of Menlo Park this was the first regular station for incandescent
lighting in the world, as the Pearl Street station in New York did not go into
operation until September of the same year. This historic plant was
hurriedly thrown together on Crown land, and would doubtless have been
the nucleus of a great system but for the passage of the English electric
lighting act of 1882, which at once throttled the industry by its absurd
restrictive provisions, and which, though greatly modified, has left England
ever since in a condition of serious inferiority as to development in electric
light and power. The streets and bridges of Holborn Viaduct were lighted by
lamps turned on and off from the station, as well as the famous City Temple
of Dr. Joseph Parker, the first church in the world to be lighted by
incandescent lamps—indeed, so far as can be ascertained, the first church to
be illuminated by electricity in any form. Mr. W. J. Hammer, who supplies
some very interesting notes on the installation, says: "I well remember the
astonishment of Doctor Parker and his associates when they noted the
difference of temperature as compared with gas. I was informed that the
people would not go in the gallery in warm weather, owing to the great heat
caused by the many gas jets, whereas on the introduction of the
incandescent lamp there was no complaint." The telegraph operating-room
of the General Post-Office, at St. Martin's-Le Grand and Newgate Street
nearby, was supplied with four hundred lamps through the instrumentality
of Mr. (Sir) W. H. Preece, who, having been seriously sceptical as to Mr.
Edison's results, became one of his most ardent advocates, and did much to
facilitate the introduction of the light. This station supplied its customers by
a network of feeders and mains of the standard underground two-wire
Edison tubing-conductors in sections of iron pipe—such as was used
subsequently in New York, Milan, and other cities. It also had a measuring
system for the current, employing the Edison electrolytic meter. Arc lamps
were operated from its circuits, and one of the first sets of practicable
company, and in a very short time the installation of plants began in various
countries—France, Italy, Holland, Belgium, etc.

system for the current, employing the Edison electrolytic meter. Arc lamps
were operated from its circuits, and one of the first sets of practicable
Page 228
storage batteries was used experimentally at the station. In connection with
these batteries Mr. Hammer tells a characteristic anecdote of Edison: "A
careless boy passing through the station whistling a tune and swinging
carelessly a hammer in his hand, rapped a carboy of sulphuric acid which
happened to be on the floor above a 'Jumbo' dynamo. The blow broke the
glass carboy, and the acid ran down upon the field magnets of the dynamo,
destroying the windings of one of the twelve magnets. This accident
happened while I was taking a vacation in Germany, and a prominent
scientific man connected with the company cabled Mr. Edison to know
whether the machine would work if the coil was cut out. Mr. Edison sent
the laconic reply: 'Why doesn't he try it and see?' Mr. E. H. Johnson was
kept busy not only with the cares and responsibilities of this pioneer
English plant, but by negotiations as to company formations, hearings
before Parliamentary committees, and particularly by distinguished visitors,
including all the foremost scientific men in England, and a great many well-
known members of the peerage. Edison was fortunate in being represented
by a man with so much address, intimate knowledge of the subject, and
powers of explanation. As one of the leading English papers said at the
time, with equal humor and truth: 'There is but one Edison, and Johnson is
his prophet.'"
As the plant continued in operation, various details and ideas of
improvement emerged, and Mr. Hammer says: "Up to the time of the
construction of this plant it had been customary to place a single-pole
switch on one wire and a safety fuse on the other; and the practice of
putting fuses on both sides of a lighting circuit was first used here. Some of
the first, if not the very first, of the insulated fixtures were used in this
plant, and many of the fixtures were equipped with ball insulating joints,
enabling the chandeliers—or 'electroliers'—to be turned around, as was
common with the gas chandeliers. This particular device was invented by
Mr. John B. Verity, whose firm built many of the fixtures for the Edison
Company, and constructed the notable electroliers shown at the Crystal
Palace Exposition of 1882."
We have made a swift survey of developments from the time when the
system of lighting was ready for use, and when the staff scattered to
introduce it. It will be readily understood that Edison did not sit with folded
hands or drop into complacent satisfaction the moment he had reached the
practical stage of commercial exploitation. He was not willing to say "Let

hands or drop into complacent satisfaction the moment he had reached the
practical stage of commercial exploitation. He was not willing to say "Let
Page 229
us rest and be thankful," as was one of England's great Liberal leaders after
a long period of reform. On the contrary, he was never more active than
immediately after the work we have summed up at the beginning of this
chapter. While he had been pursuing his investigations of the generator in
conjunction with the experiments on the incandescent lamp, he gave much
thought to the question of distribution of the current over large areas,
revolving in his mind various plans for the accomplishment of this purpose,
and keeping his mathematicians very busy working on the various schemes
that suggested themselves from time to time. The idea of a complete system
had been in his mind in broad outline for a long time, but did not crystallize
into commercial form until the incandescent lamp was an accomplished
fact. Thus in January, 1880, his first patent application for a "System of
Electrical Distribution" was signed. It was filed in the Patent Office a few
days later, but was not issued as a patent until August 30, 1887. It covered,
fundamentally, multiple arc distribution, how broadly will be understood
from the following extracts from the New York Electrical Review of
September 10, 1887: "It would appear as if the entire field of multiple
distribution were now in the hands of the owners of this patent.... The patent
is about as broad as a patent can be, being regardless of specific devices,
and laying a powerful grasp on the fundamental idea of multiple
distribution from a number of generators throughout a metallic circuit."
Mr. Edison made a number of other applications for patents on electrical
distribution during the year 1880. Among these was the one covering the
celebrated "Feeder" invention, which has been of very great commercial
importance in the art, its object being to obviate the "drop" in pressure,
rendering lights dim in those portions of an electric-light system that were
remote from the central station. [10]
[Footnote 10: For further explanation of "Feeder" patent,
see Appendix.]
From these two patents alone, which were absolutely basic and
fundamental in effect, and both of which were, and still are, put into actual
use wherever central-station lighting is practiced, the reader will see that
Mr. Edison's patient and thorough study, aided by his keen foresight and
unerring judgment, had enabled him to grasp in advance with a master hand
the chief and underlying principles of a true system—that system which has
a long period of reform. On the contrary, he was never more active than

the chief and underlying principles of a true system—that system which has
Page 230
since been put into practical use all over the world, and whose elements do
not need the touch or change of more modern scientific knowledge.
These patents were not by any means all that he applied for in the year
1880, which it will be remembered was the year in which he was perfecting
the incandescent electric lamp and methods, to put into the market for
competition with gas. It was an extraordinarily busy year for Mr. Edison
and his whole force, which from time to time was increased in number.
Improvement upon improvement was the order of the day. That which was
considered good to-day was superseded by something better and more
serviceable to-morrow. Device after device, relating to some part of the
entire system, was designed, built, and tried, only to be rejected ruthlessly
as being unsuitable; but the pursuit was not abandoned. It was renewed over
and over again in innumerable ways until success had been attained.
During the year 1880 Edison had made application for sixty patents, of
which thirty-two were in relation to incandescent lamps; seven covered
inventions relating to distributing systems (including the two above
particularized); five had reference to inventions of parts, such as motors,
sockets, etc.; six covered inventions relating to dynamo-electric machines;
three related to electric railways, and seven to miscellaneous apparatus,
such as telegraph relays, magnetic ore separators, magneto signalling
apparatus, etc.
The list of Mr. Edison's patents (see Appendices) is not only a monument
to his life's work, but serves to show what subjects he has worked on from
year to year since 1868. The reader will see from an examination of this list
that the years 1880, 1881, 1882, and 1883 were the most prolific periods of
invention. It is worth while to scrutinize this list closely to appreciate the
wide range of his activities. Not that his patents cover his entire range of
work by any means, for his note-books reveal a great number of major and
minor inventions for which he has not seen fit to take out patents.
Moreover, at the period now described Edison was the victim of a dishonest
patent solicitor, who deprived him of a number of patents in the following
manner:
"Around 1881-82 I had several solicitors attending to different classes of
work. One of these did me a most serious injury. It was during the time that
I was developing my electric-lighting system, and I was working and
thinking very hard in order to cover all the numerous parts, in order that it
not need the touch or change of more modern scientific knowledge.
These patents were not by any means all that he applied for in the year
1880, which it will be remembered was the year in which he was perfecting
the incandescent electric lamp and methods, to put into the market for
competition with gas. It was an extraordinarily busy year for Mr. Edison
and his whole force, which from time to time was increased in number.
Improvement upon improvement was the order of the day. That which was
considered good to-day was superseded by something better and more
serviceable to-morrow. Device after device, relating to some part of the
entire system, was designed, built, and tried, only to be rejected ruthlessly
as being unsuitable; but the pursuit was not abandoned. It was renewed over
and over again in innumerable ways until success had been attained.
During the year 1880 Edison had made application for sixty patents, of
which thirty-two were in relation to incandescent lamps; seven covered
inventions relating to distributing systems (including the two above
particularized); five had reference to inventions of parts, such as motors,
sockets, etc.; six covered inventions relating to dynamo-electric machines;
three related to electric railways, and seven to miscellaneous apparatus,
such as telegraph relays, magnetic ore separators, magneto signalling
apparatus, etc.
The list of Mr. Edison's patents (see Appendices) is not only a monument
to his life's work, but serves to show what subjects he has worked on from
year to year since 1868. The reader will see from an examination of this list
that the years 1880, 1881, 1882, and 1883 were the most prolific periods of
invention. It is worth while to scrutinize this list closely to appreciate the
wide range of his activities. Not that his patents cover his entire range of
work by any means, for his note-books reveal a great number of major and
minor inventions for which he has not seen fit to take out patents.
Moreover, at the period now described Edison was the victim of a dishonest
patent solicitor, who deprived him of a number of patents in the following
manner:
"Around 1881-82 I had several solicitors attending to different classes of
work. One of these did me a most serious injury. It was during the time that
I was developing my electric-lighting system, and I was working and
thinking very hard in order to cover all the numerous parts, in order that it
Page 231
would be complete in every detail. I filed a great many applications for
patents at that time, but there were seventy-eight of the inventions I made in
that period that were entirely lost to me and my company by reason of the
dishonesty of this patent solicitor. Specifications had been drawn, and I had
signed and sworn to the application for patents for these seventy-eight
inventions, and naturally I supposed they had been filed in the regular way.
"As time passed I was looking for some action of the Patent Office, as
usual, but none came. I thought it very strange, but had no suspicions until I
began to see my inventions recorded in the Patent Office Gazette as being
patented by others. Of course I ordered an investigation, and found that the
patent solicitor had drawn from the company the fees for filing all these
applications, but had never filed them. All the papers had disappeared,
however, and what he had evidently done was to sell them to others, who
had signed new applications and proceeded to take out patents themselves
on my inventions. I afterward found that he had been previously mixed up
with a somewhat similar crooked job in connection with telephone patents.
"I am free to confess that the loss of these seventy-eight inventions has
left a sore spot in me that has never healed. They were important, useful,
and valuable, and represented a whole lot of tremendous work and mental
effort, and I had had a feeling of pride in having overcome through them a
great many serious obstacles, One of these inventions covered the
multipolar dynamo. It was an elaborated form of the type covered by my
patent No. 219,393 which had a ring armature. I modified and improved on
this form and had a number of pole pieces placed all around the ring, with a
modified form of armature winding. I built one of these machines and ran it
successfully in our early days at the Goerck Street shop.
"It is of no practical use to mention the man's name. I believe he is dead,
but he may have left a family. The occurrence is a matter of the old Edison
Company's records."
It will be seen from an examination of the list of patents in the Appendix
that Mr. Edison has continued year after year adding to his contributions to
the art of electric lighting, and in the last twenty-eight years—1880-1908—
has taken out no fewer than three hundred and seventy-five patents in this
branch of industry alone. These patents may be roughly tabulated as
follows:

Dynamo-electric machines and accessories....................106
Minor parts, such as sockets, switches, safety catches,
meters, underground conductors and parts, etc............... 43
Quite naturally most of these patents cover inventions that are in the
nature of improvements or based upon devices which he had already
created; but there are a number that relate to inventions absolutely
fundamental and original in their nature. Some of these have already been
alluded to; but among the others there is one which is worthy of special
mention in connection with the present consideration of a complete system.
This is patent No. 274,290, applied for November 27, 1882, and is known
as the "Three-wire" patent. It is described more fully in the Appendix.
The great importance of the "Feeder" and "Three-wire" inventions will be
apparent when it is realized that without them it is a question whether
electric light could be sold to compete with low-priced gas, on account of
the large investment in conductors that would be necessary. If a large city
area were to be lighted from a central station by means of copper
conductors running directly therefrom to all parts of the district, it would be
necessary to install large conductors, or suffer such a drop of pressure at the
ends most remote from the station as to cause the lights there to burn with a
noticeable diminution of candle-power. The Feeder invention overcame this
trouble, and made it possible to use conductors ONLY ONE-EIGHTH THE
SIZE that would otherwise have been necessary to produce the same
results.
A still further economy in cost of conductors was effected by the "Three-
wire" invention, by the use of which the already diminished conductors
could be still further reduced TO ONE-THIRD of this smaller size, and at
the same time allow of the successful operation of the station with far better
results than if it were operated exactly as at first conceived. The Feeder and
Three-wire systems are at this day used in all parts of the world, not only in
central-station work, but in the installation and operation of isolated
electric-light plants in large buildings. No sensible or efficient station
manager or electric contractor would ever think of an installation made
upon any other plan. Thus Mr. Edison's early conceptions of the necessities
of a complete system, one of them made even in advance of practice, have
stood firm, unimproved, and unchanged during the past twenty-eight years,

electrical science and art than has been known during any similar art or
period of time since the world began.
It must be remembered that the complete system in all its parts is not
comprised in the few of Mr. Edison's patents, of which specific mention is
here made. In order to comprehend the magnitude and extent of his work
and the quality of his genius, it is necessary to examine minutely the list of
patents issued for the various elements which go to make up such a system.
To attempt any relation in detail of the conception and working-out of each
part or element; to enter into any description of the almost innumerable
experiments and investigations that were made would entail the writing of
several volumes, for Mr. Edison's close-written note-books covering these
subjects number nearly two hundred.
It is believed that enough evidence has been given in this chapter to lead
to an appreciation of the assiduous work and practical skill involved in
"inventing a system" of lighting that would surpass, and to a great extent, in
one single quarter of a century, supersede all the other methods of
illumination developed during long centuries. But it will be appropriate
before passing on to note that on January 17, 1908, while this biography
was being written, Mr. Edison became the fourth recipient of the John Fritz
gold medal for achievement in industrial progress. This medal was founded
in 1902 by the professional friends and associates of the veteran American
ironmaster and metallurgical inventor, in honor of his eightieth birthday.
Awards are made by a board of sixteen engineers appointed in equal
numbers from the four great national engineering societies—the American
Society of Civil Engineers, the American Institute of Mining Engineers, the
American Society of Mechanical Engineers, and the American Institute of
Electrical Engineers, whose membership embraces the very pick and flower
of professional engineering talent in America. Up to the time of the Edison
award, three others had been made. The first was to Lord Kelvin, the Nestor
of physics in Europe, for his work in submarine-cable telegraphy and other
scientific achievement. The second was to George Westinghouse for the air-
brake. The third was to Alexander Graham Bell for the invention and
introduction of the telephone. The award to Edison was not only for his
inventions in duplex and quadruplex telegraphy, and for the phonograph,
but for the development of a commercially practical incandescent lamp, and
the development of a complete system of electric lighting, including
electrical science and art than has been known during any similar art or

CHAPTER XV
INTRODUCTION OF THE EDISON ELECTRIC LIGHT
IN the previous chapter on the invention of a system, the narrative has
been carried along for several years of activity up to the verge of the
successful and commercial application of Edison's ideas and devices for
incandescent electric lighting. The story of any one year in this period, if
treated chronologically, would branch off in a great many different
directions, some going back to earlier work, others forward to arts not yet
within the general survey; and the effect of such treatment would be
confusing. In like manner the development of the Edison lighting system
followed several concurrent, simultaneous lines of advance; and an effort
was therefore made in the last chapter to give a rapid glance over the whole
movement, embracing a term of nearly five years, and including in its scope
both the Old World and the New. What is necessary to the completeness of
the story at this stage is not to recapitulate, but to take up some of the loose
ends of threads woven in and follow them through until the clear and
comprehensive picture of events can be seen.
Some things it would be difficult to reproduce in any picture of the art
and the times. One of the greatest delusions of the public in regard to any
notable invention is the belief that the world is waiting for it with open arms
and an eager welcome. The exact contrary is the truth. There is not a single
new art or device the world has ever enjoyed of which it can be said that it
was given an immediate and enthusiastic reception. The way of the inventor
is hard. He can sometimes raise capital to help him in working out his crude
conceptions, but even then it is frequently done at a distressful cost of
personal surrender. When the result is achieved the invention makes its
appeal on the score of economy of material or of effort; and then "labor"
often awaits with crushing and tyrannical spirit to smash the apparatus or
forbid its very use. Where both capital and labor are agreed that the object
is worthy of encouragement, there is the supreme indifference of the public
to overcome, and the stubborn resistance of pre-existing devices to combat.

INTRODUCTION OF THE EDISON ELECTRIC LIGHT
IN the previous chapter on the invention of a system, the narrative has
been carried along for several years of activity up to the verge of the

incandescent electric lighting. The story of any one year in this period, if

the story at this stage is not to recapitulate, but to take up some of the loose
ends of threads woven in and follow them through until the clear and
comprehensive picture of events can be seen.
Some things it would be difficult to reproduce in any picture of the art
and the times. One of the greatest delusions of the public in regard to any
notable invention is the belief that the world is waiting for it with open arms
and an eager welcome. The exact contrary is the truth. There is not a single
new art or device the world has ever enjoyed of which it can be said that it
was given an immediate and enthusiastic reception. The way of the inventor
is hard. He can sometimes raise capital to help him in working out his crude
conceptions, but even then it is frequently done at a distressful cost of

appeal on the score of economy of material or of effort; and then "labor"
often awaits with crushing and tyrannical spirit to smash the apparatus or

is worthy of encouragement, there is the supreme indifference of the public
to overcome, and the stubborn resistance of pre-existing devices to combat.
The years of hardship and struggle are thus prolonged, the chagrin of
Page 236
poverty and neglect too frequently embitters the inventor's scanty bread;
and one great spirit after another has succumbed to the defeat beyond which
lay the procrastinated triumph so dearly earned. Even in America, where the
adoption of improvements and innovations is regarded as so prompt and
sure, and where the huge tolls of the Patent Office and the courts bear
witness to the ceaseless efforts of the inventor, it is impossible to deny the
sad truth that unconsciously society discourages invention rather than
invites it. Possibly our national optimism as revealed in invention—the
seeking a higher good—needs some check. Possibly the leaders would
travel too fast and too far on the road to perfection if conservatism did not
also play its salutary part in insisting that the procession move forward as a
whole.
Edison and his electric light were happily more fortunate than other men
and inventions, in the relative cordiality of the reception given them. The
merit was too obvious to remain unrecognized. Nevertheless, it was through
intense hostility and opposition that the young art made its way, pushed
forward by Edison's own strong personality and by his unbounded,
unwavering faith in the ultimate success of his system. It may seem strange
that great effort was required to introduce a light so manifestly convenient,
safe, agreeable, and advantageous, but the facts are matter of record; and to-
day the recollection of some of the episodes brings a fierce glitter into the
eye and keen indignation into the voice of the man who has come so
victoriously through it all.
It was not a fact at any time that the public was opposed to the idea of the
electric light. On the contrary, the conditions for its acceptance had been
ripening fast. Yet the very vogue of the electric arc light made harder the
arrival of the incandescent. As a new illuminant for the streets, the arc had
become familiar, either as a direct substitute for the low gas lamp along the
sidewalk curb, or as a novel form of moonlight, raised in groups at the top
of lofty towers often a hundred and fifty feet high. Some of these lights
were already in use for large indoor spaces, although the size of the unit, the
deadly pressure of the current, and the sputtering sparks from the carbons
made them highly objectionable for such purposes. A number of parent arc-
lighting companies were in existence, and a great many local companies
had been called into being under franchises for commercial business and to
execute regular city contracts for street lighting. In this manner a good deal
of capital and the energies of many prominent men in politics and business
and one great spirit after another has succumbed to the defeat beyond which
lay the procrastinated triumph so dearly earned. Even in America, where the
adoption of improvements and innovations is regarded as so prompt and

of capital and the energies of many prominent men in politics and business
Page 237
had been rallied distinctively to the support of arc lighting. Under the
inventive leadership of such brilliant men as Brush, Thomson, Weston, and
Van Depoele—there were scores of others—the industry had made
considerable progress and the art had been firmly established. Here lurked,
however, very vigorous elements of opposition, for Edison predicted from
the start the superiority of the small electric unit of light, and devoted
himself exclusively to its perfection and introduction. It can be readily seen
that this situation made it all the more difficult for the Edison system to
secure the large sums of money needed for its exploitation, and to obtain
new franchises or city ordinances as a public utility. Thus in a curious
manner the modern art of electric lighting was in a very true sense divided
against itself, with intense rivalries and jealousies which were none the less
real because they were but temporary and occurred in a field where ultimate
union of forces was inevitable. For a long period the arc was dominant and
supreme in the lighting branch of the electrical industries, in all respects,
whether as to investment, employees, income, and profits, or in respect to
the manufacturing side. When the great National Electric Light Association
was formed in 1885, its organizers were the captains of arc lighting, and not
a single Edison company or licensee could be found in its ranks, or dared to
solicit membership. The Edison companies, soon numbering about three
hundred, formed their own association—still maintained as a separate and
useful body—and the lines were tensely drawn in a way that made it none
too easy for the Edison service to advance, or for an impartial man to
remain friendly with both sides. But the growing popularity of incandescent
lighting, the flexibility and safety of the system, the ease with which other
electric devices for heat, power, etc., could be put indiscriminately on the
same circuits with the lamps, in due course rendered the old attitude of
opposition obviously foolish and untenable. The United States Census
Office statistics of 1902 show that the income from incandescent lighting
by central stations had by that time become over 52 per cent. of the total,
while that from arc lighting was less than 29; and electric-power service
due to the ease with which motors could be introduced on incandescent
circuits brought in 15 per cent. more. Hence twenty years after the first
Edison stations were established the methods they involved could be fairly
credited with no less than 67 per cent. of all central-station income in the
country, and the proportion has grown since then. It will be readily
understood that under these conditions the modern lighting company

Van Depoele—there were scores of others—the industry had made

country, and the proportion has grown since then. It will be readily
understood that under these conditions the modern lighting company
Page 238
supplies to its customers both incandescent and arc lighting, frequently
from the same dynamo-electric machinery as a source of current; and that
the old feud as between the rival systems has died out. In fact, for some
years past the presidents of the National Electric Light Association have
been chosen almost exclusively from among the managers of the great
Edison lighting companies in the leading cities.
The other strong opposition to the incandescent light came from the gas
industry. There also the most bitter feeling was shown. The gas manager did
not like the arc light, but it interfered only with his street service, which was
not his largest source of income by any means. What did arouse his ire and
indignation was to find this new opponent, the little incandescent lamp,
pushing boldly into the field of interior lighting, claiming it on a great
variety of grounds of superiority, and calmly ignoring the question of price,
because it was so much better. Newspaper records and the pages of the
technical papers of the day show to what an extent prejudice and passion
were stirred up and the astounding degree to which the opposition to the
new light was carried.
Here again was given a most convincing demonstration of the truth that
such an addition to the resources of mankind always carries with it
unsuspected benefits even for its enemies. In two distinct directions the gas
art was immediately helped by Edison's work. The competition was most
salutary in the stimulus it gave to improvements in processes for making,
distributing, and using gas, so that while vast economies have been effected
at the gas works, the customer has had an infinitely better light for less
money. In the second place, the coming of the incandescent light raised the
standard of illumination in such a manner that more gas than ever was
wanted in order to satisfy the popular demand for brightness and brilliancy
both indoors and on the street. The result of the operation of these two
forces acting upon it wholly from without, and from a rival it was desired to
crush, has been to increase enormously the production and use of gas in the
last twenty-five years. It is true that the income of the central stations is
now over $300,000,000 a year, and that isolated-plant lighting represents
also a large amount of diverted business; but as just shown, it would
obviously be unfair to regard all this as a loss from the standpoint of gas. It
is in great measure due to new sources of income developed by electricity
for itself.

not his largest source of income by any means. What did arouse his ire and
indignation was to find this new opponent, the little incandescent lamp,
pushing boldly into the field of interior lighting, claiming it on a great
variety of grounds of superiority, and calmly ignoring the question of price,
because it was so much better. Newspaper records and the pages of the
technical papers of the day show to what an extent prejudice and passion
were stirred up and the astounding degree to which the opposition to the
new light was carried.
Here again was given a most convincing demonstration of the truth that
such an addition to the resources of mankind always carries with it
unsuspected benefits even for its enemies. In two distinct directions the gas
art was immediately helped by Edison's work. The competition was most
salutary in the stimulus it gave to improvements in processes for making,
distributing, and using gas, so that while vast economies have been effected
at the gas works, the customer has had an infinitely better light for less
money. In the second place, the coming of the incandescent light raised the
standard of illumination in such a manner that more gas than ever was
wanted in order to satisfy the popular demand for brightness and brilliancy
both indoors and on the street. The result of the operation of these two
forces acting upon it wholly from without, and from a rival it was desired to
crush, has been to increase enormously the production and use of gas in the
last twenty-five years. It is true that the income of the central stations is
now over $300,000,000 a year, and that isolated-plant lighting represents
also a large amount of diverted business; but as just shown, it would
obviously be unfair to regard all this as a loss from the standpoint of gas. It
is in great measure due to new sources of income developed by electricity
for itself.

A retrospective survey shows that had the men in control of the American
gas-lighting art, in 1880, been sufficiently far-sighted, and had they taken a
broader view of the situation, they might easily have remained dominant in
the whole field of artificial lighting by securing the ownership of the patents
and devices of the new industry. Apparently not a single step of that kind
was undertaken, nor probably was there a gas manager who would have
agreed with Edison in the opinion written down by him at the time in little
note-book No. 184, that gas properties were having conferred on them an
enhanced earning capacity. It was doubtless fortunate and providential for
the electric-lighting art that in its state of immature development it did not
fall into the hands of men who were opposed to its growth, and would not
have sought its technical perfection. It was allowed to carve out its own
career, and thus escaped the fate that is supposed to have attended other
great inventions—of being bought up merely for purposes of suppression.
There is a vague popular notion that this happens to the public loss; but the
truth is that no discovery of any real value is ever entirely lost. It may be
retarded; but that is all. In the case of the gas companies and the
incandescent light, many of them to whom it was in the early days as great
an irritant as a red flag to a bull, emulated the performance of that animal
and spent a great deal of money and energy in bellowing and throwing up
dirt in the effort to destroy the hated enemy. This was not long nor
universally the spirit shown; and to-day in hundreds of cities the electric
and gas properties are united under the one management, which does not
find it impossible to push in a friendly and progressive way the use of both
illuminants. The most conspicuous example of this identity of interest is
given in New York itself.
So much for the early opposition, of which there was plenty. But it may
be questioned whether inertia is not equally to be dreaded with active ill-
will. Nothing is more difficult in the world than to get a good many
hundreds of thousands or millions of people to do something they have
never done before. A very real difficulty in the introduction of his lamp and
lighting system by Edison lay in the absolute ignorance of the public at
large, not only as to its merits, but as to the very appearance of the light,
Some few thousand people had gone out to Menlo Park, and had there seen
the lamps in operation at the laboratory or on the hillsides, but they were an
insignificant proportion of the inhabitants of the United States. Of course, a
great many accounts were written and read, but while genuine interest was

great many accounts were written and read, but while genuine interest was
Page 240
aroused it was necessarily apathetic. A newspaper description or a magazine
article may be admirably complete in itself, with illustrations, but until
some personal experience is had of the thing described it does not convey a
perfect mental picture, nor can it always make the desire active and
insistent. Generally, people wait to have the new thing brought to them; and
hence, as in the case of the Edison light, an educational campaign of a
practical nature is a fundamental condition of success.
Another serious difficulty confronting Edison and his associates was that
nowhere in the world were there to be purchased any of the appliances
necessary for the use of the lighting system. Edison had resolved from the
very first that the initial central station embodying his various ideas should
be installed in New York City, where he could superintend the installation
personally, and then watch the operation. Plans to that end were now
rapidly maturing; but there would be needed among many other things—
every one of them new and novel—dynamos, switchboards, regulators,
pressure and current indicators, fixtures in great variety, incandescent
lamps, meters, sockets, small switches, underground conductors, junction-
boxes, service-boxes, manhole-boxes, connectors, and even specially made
wire. Now, not one of these miscellaneous things was in existence; not an
outsider was sufficiently informed about such devices to make them on
order, except perhaps the special wire. Edison therefore started first of all a
lamp factory in one of the buildings at Menlo Park, equipped it with novel
machinery and apparatus, and began to instruct men, boys, and girls, as they
could be enlisted, in the absolutely new art, putting Mr. Upton in charge.
With regard to the conditions attendant upon the manufacture of the
lamps, Edison says: "When we first started the electric light we had to have
a factory for manufacturing lamps. As the Edison Light Company did not
seem disposed to go into manufacturing, we started a small lamp factory at
Menlo Park with what money I could raise from my other inventions and
royalties, and some assistance. The lamps at that time were costing about
$1.25 each to make, so I said to the company: 'If you will give me a
contract during the life of the patents, I will make all the lamps required by
the company and deliver them for forty cents.' The company jumped at the
chance of this offer, and a contract was drawn up. We then bought at a
receiver's sale at Harrison, New Jersey, a very large brick factory building
which had been used as an oil-cloth works. We got it at a great bargain, and
only paid a small sum down, and the balance on mortgage. We moved the

Page 241
lamp works from Menlo Park to Harrison. The first year the lamps cost us
about $1.10 each. We sold them for forty cents; but there were only about
twenty or thirty thousand of them. The next year they cost us about seventy
cents, and we sold them for forty. There were a good many, and we lost
more money the second year than the first. The third year I succeeded in
getting up machinery and in changing the processes, until it got down so
that they cost somewhere around fifty cents. I still sold them for forty cents,
and lost more money that year than any other, because the sales were
increasing rapidly. The fourth year I got it down to thirty-seven cents, and I
made all the money up in one year that I had lost previously. I finally got it
down to twenty-two cents, and sold them for forty cents; and they were
made by the million. Whereupon the Wall Street people thought it was a
very lucrative business, so they concluded they would like to have it, and
bought us out.
"One of the incidents which caused a very great cheapening was that,
when we started, one of the important processes had to be done by experts.
This was the sealing on of the part carrying the filament into the globe,
which was rather a delicate operation in those days, and required several
months of training before any one could seal in a fair number of parts in a
day. When we got to the point where we employed eighty of these experts
they formed a union; and knowing it was impossible to manufacture lamps
without them, they became very insolent. One instance was that the son of
one of these experts was employed in the office, and when he was told to do
anything would not do it, or would give an insolent reply. He was
discharged, whereupon the union notified us that unless the boy was taken
back the whole body would go out. It got so bad that the manager came to
me and said he could not stand it any longer; something had got to be done.
They were not only more surly; they were diminishing the output, and it
became impossible to manage the works. He got me enthused on the
subject, so I started in to see if it were not possible to do that operation by
machinery. After feeling around for some days I got a clew how to do it. I
then put men on it I could trust, and made the preliminary machinery. That
seemed to work pretty well. I then made another machine which did the
work nicely. I then made a third machine, and would bring in yard men,
ordinary laborers, etc., and when I could get these men to put the parts
together as well as the trained experts, in an hour, I considered the machine
complete. I then went secretly to work and made thirty of the machines. Up
about $1.10 each. We sold them for forty cents; but there were only about
twenty or thirty thousand of them. The next year they cost us about seventy

Page 242
in the top loft of the factory we stored those machines, and at night we put
up the benches and got everything all ready. Then we discharged the office-
boy. Then the union went out. It has been out ever since.
"When we formed the works at Harrison we divided the interests into one
hundred shares or parts at $100 par. One of the boys was hard up after a
time, and sold two shares to Bob Cutting. Up to that time we had never paid
anything; but we got around to the point where the board declared a
dividend every Saturday night. We had never declared a dividend when
Cutting bought his shares, and after getting his dividends for three weeks in
succession, he called up on the telephone and wanted to know what kind of
a concern this was that paid a weekly dividend. The works sold for
$1,085,000."
Incidentally it may be noted, as illustrative of the problems brought to
Edison, that while he had the factory at Harrison an importer in the Chinese
trade went to him and wanted a dynamo to be run by hand power. The
importer explained that in China human labor was cheaper than steam
power. Edison devised a machine to answer the purpose, and put long
spokes on it, fitted it up, and shipped it to China. He has not, however,
heard of it since.
For making the dynamos Edison secured, as noted in the preceding
chapter, the Roach Iron Works on Goerck Street, New York, and this was
also equipped. A building was rented on Washington Street, where
machinery and tools were put in specially designed for making the
underground tube conductors and their various paraphernalia; and the
faithful John Kruesi was given charge of that branch of production. To
Sigmund Bergmann, who had worked previously with Edison on telephone
apparatus and phonographs, and was already making Edison specialties in a
small way in a loft on Wooster Street, New York, was assigned the task of
constructing sockets, fixtures, meters, safety fuses, and numerous other
details.
Thus, broadly, the manufacturing end of the problem of introduction was
cared for. In the early part of 1881 the Edison Electric Light Company
leased the old Bishop mansion at 65 Fifth Avenue, close to Fourteenth
Street, for its headquarters and show-rooms. This was one of the finest
homes in the city of that period, and its acquisition was a premonitory sign
of the surrender of the famous residential avenue to commerce. The

Page 243
company needed not only offices, but, even more, such an interior as would
display to advantage the new light in everyday use; and this house with its
liberal lines, spacious halls, lofty ceilings, wide parlors, and graceful,
winding stairway was ideal for the purpose. In fact, in undergoing this
violent change, it did not cease to be a home in the real sense, for to this day
many an Edison veteran's pulse is quickened by some chance reference to
"65," where through many years the work of development by a loyal and
devoted band of workers was centred. Here Edison and a few of his
assistants from Menlo Park installed immediately in the basement a small
generating plant, at first with a gas-engine which was not successful, and
then with a Hampson high-speed engine and boiler, constituting a complete
isolated plant. The building was wired from top to bottom, and equipped
with all the appliances of the art. The experience with the little gas-engine
was rather startling. "At an early period at '65' we decided," says Edison, "to
light it up with the Edison system, and put a gas-engine in the cellar, using
city gas. One day it was not going very well, and I went down to the man in
charge and got exploring around. Finally I opened the pedestal—a
storehouse for tools, etc. We had an open lamp, and when we opened the
pedestal, it blew the doors off, and blew out the windows, and knocked me
down, and the other man."
For the next four or five years "65" was a veritable beehive, day and
night. The routine was very much the same as that at the laboratory, in its
utter neglect of the clock. The evenings were not only devoted to the
continuance of regular business, but the house was thrown open to the
public until late at night, never closing before ten o'clock, so as to give
everybody who wished an opportunity to see that great novelty of the time
—the incandescent light—whose fame had meanwhile been spreading all
over the globe. The first year, 1881, was naturally that which witnessed the
greatest rush of visitors; and the building hardly ever closed its doors till
midnight. During the day business was carried on under great stress, and
Mr. Insull has described how Edison was to be found there trying to lead the
life of a man of affairs in the conventional garb of polite society, instead of
pursuing inventions and researches in his laboratory. But the disagreeable
ordeal could not be dodged. After the experience Edison could never again
be tempted to quit his laboratory and work for any length of time; but in this
instance there were some advantages attached to the sacrifice, for the
crowds of lion-hunters and people seeking business arrangements would
display to advantage the new light in everyday use; and this house with its

Page 244
only have gone out to Menlo Park; while, on the other hand, the great plans
for lighting New York demanded very close personal attention on the spot.
As it was, not only Edison, but all the company's directors, officers, and
employees, were kept busy exhibiting and explaining the light. To the
public of that day, when the highest known form of house illuminant was
gas, the incandescent lamp, with its ability to burn in any position, its lack
of heat so that you could put your hand on the brilliant glass globe; the
absence of any vitiating effect on the atmosphere, the obvious safety from
fire; the curious fact that you needed no matches to light it, and that it was
under absolute control from a distance—these and many other features
came as a distinct revelation and marvel, while promising so much
additional comfort, convenience, and beauty in the home, that inspection
was almost invariably followed by a request for installation.
The camaraderie that existed at this time was very democratic, for all
were workers in a common cause; all were enthusiastic believers in the
doctrine they proclaimed, and hoped to profit by the opening up of the new
art. Often at night, in the small hours, all would adjourn for refreshments to
a famous resort nearby, to discuss the events of to-day and to-morrow, full
of incident and excitement. The easy relationship of the time is neatly
sketched by Edison in a humorous complaint as to his inability to keep his
own cigars: "When at '65' I used to have in my desk a box of cigars. I would
go to the box four or five times to get a cigar, but after it got circulated
about the building, everybody would come to get my cigars, so that the box
would only last about a day and a half. I was telling a gentleman one day
that I could not keep a cigar. Even if I locked them up in my desk they
would break it open. He suggested to me that he had a friend over on Eighth
Avenue who made a superior grade of cigars, and who would show them a
trick. He said he would have some of them made up with hair and old paper,
and I could put them in without a word and see the result. I thought no more
about the matter. He came in two or three months after, and said: 'How did
that cigar business work?' I didn't remember anything about it. On coming
to investigate, it appeared that the box of cigars had been delivered and had
been put in my desk, and I had smoked them all! I was too busy on other
things to notice."
It was no uncommon sight to see in the parlors in the evening John
Pierpont Morgan, Norvin Green, Grosvenor P. Lowrey, Henry Villard,
for lighting New York demanded very close personal attention on the spot.

Page 245
Robert L. Cutting, Edward D. Adams, J. Hood Wright, E. G. Fabbri, R. M.
Galloway, and other men prominent in city life, many of them stock-holders
and directors; all interested in doing this educational work. Thousands of
persons thus came—bankers, brokers, lawyers, editors, and reporters,
prominent business men, electricians, insurance experts, under whose
searching and intelligent inquiries the facts were elicited, and general
admiration was soon won for the system, which in advance had solved so
many new problems. Edison himself was in universal request and the
subject of much adulation, but altogether too busy and modest to be spoiled
by it. Once in a while he felt it his duty to go over the ground with scientific
visitors, many of whom were from abroad, and discuss questions which
were not simply those of technique, but related to newer phenomena, such
as the action of carbon, the nature and effects of high vacua; the principles
of electrical subdivision; the value of insulation, and many others which,
unfortunate to say, remain as esoteric now as they were then, ever fruitful
themes of controversy.
Speaking of those days or nights, Edison says: "Years ago one of the
great violinists was Remenyi. After his performances were over he used to
come down to '65' and talk economics, philosophy, moral science, and
everything else. He was highly educated and had great mental capacity. He
would talk with me, but I never asked him to bring his violin. One night he
came with his violin, about twelve o'clock. I had a library at the top of the
house, and Remenyi came up there. He was in a genial humor, and played
the violin for me for about two hours—$2000 worth. The front doors were
closed, and he walked up and down the room as he played. After that, every
time he came to New York he used to call at '65' late at night with his violin.
If we were not there, he could come down to the slums at Goerck Street,
and would play for an hour or two and talk philosophy. I would talk for the
benefit of his music. Henry E. Dixey, then at the height of his 'Adonis'
popularity, would come in in those days, after theatre hours, and would
entertain us with stories—1882-84. Another visitor who used to give us a
good deal of amusement and pleasure was Captain Shaw, the head of the
London Fire Brigade. He was good company. He would go out among the
fire-laddies and have a great time. One time Robert Lincoln and Anson
Stager, of the Western Union, interested in the electric light, came on to
make some arrangement with Major Eaton, President of the Edison Electric
Light Company. They came to '65' in the afternoon, and Lincoln
Galloway, and other men prominent in city life, many of them stock-holders
and directors; all interested in doing this educational work. Thousands of
persons thus came—bankers, brokers, lawyers, editors, and reporters,
prominent business men, electricians, insurance experts, under whose
searching and intelligent inquiries the facts were elicited, and general
admiration was soon won for the system, which in advance had solved so
many new problems. Edison himself was in universal request and the
subject of much adulation, but altogether too busy and modest to be spoiled
by it. Once in a while he felt it his duty to go over the ground with scientific
visitors, many of whom were from abroad, and discuss questions which
were not simply those of technique, but related to newer phenomena, such
as the action of carbon, the nature and effects of high vacua; the principles
of electrical subdivision; the value of insulation, and many others which,
unfortunate to say, remain as esoteric now as they were then, ever fruitful
themes of controversy.
Speaking of those days or nights, Edison says: "Years ago one of the
great violinists was Remenyi. After his performances were over he used to
come down to '65' and talk economics, philosophy, moral science, and
everything else. He was highly educated and had great mental capacity. He
would talk with me, but I never asked him to bring his violin. One night he
came with his violin, about twelve o'clock. I had a library at the top of the

commenced telling stories—like his father. They told stories all the
afternoon, and that night they left for Chicago. When they got to Cleveland,
it dawned upon them that they had not done any business, so they had to
come back on the next train to New York to transact it. They were interested
in the Chicago Edison Company, now one of the largest of the systems in
the world. Speaking of telling stories, I once got telling a man stories at the
Harrison lamp factory, in the yard, as he was leaving. It was winter, and he
was all in furs. I had nothing on to protect me against the cold. I told him
one story after the other—six of them. Then I got pleurisy, and had to be
shipped to Florida for cure."
The organization of the Edison Electric Light Company went back to
1878; but up to the time of leasing 65 Fifth Avenue it had not been engaged
in actual business. It had merely enjoyed the delights of anxious
anticipation, and the perilous pleasure of backing Edison's experiments.
Now active exploitation was required. Dr. Norvin Green, the well-known
President of the Western Union Telegraph Company, was president also of
the Edison Company, but the pressing nature of his regular duties left him
no leisure for such close responsible management as was now required.
Early in 1881 Mr. Grosvenor P. Lowrey, after consultation with Mr. Edison,
prevailed upon Major S. B. Eaton, the leading member of a very prominent
law firm in New York, to accept the position of vice-president and general
manager of the company, in which, as also in some of the subsidiary Edison
companies, and as president, he continued actively and energetically for
nearly four years, a critical, formative period in which the solidity of the
foundation laid is attested by the magnitude and splendor of the
superstructure.
The fact that Edison conferred at this point with Mr. Lowrey should,
perhaps, be explained in justice to the distinguished lawyer, who for so
many years was the close friend of the inventor, and the chief counsel in all
the tremendous litigation that followed the effort to enforce and validate the
Edison patents. As in England Mr. Edison was fortunate in securing the
legal assistance of Sir Richard Webster, afterward Lord Chief Justice of
England, so in America it counted greatly in his favor to enjoy the advocacy
of such a man as Lowrey, prominent among the famous leaders of the New
York bar. Born in Massachusetts, Mr. Lowrey, in his earlier days of
straitened circumstances, was accustomed to defray some portion of his
educational expenses by teaching music in the Berkshire villages, and by a
afternoon, and that night they left for Chicago. When they got to Cleveland,
it dawned upon them that they had not done any business, so they had to

Page 247
curious coincidence one of his pupils was F. L. Pope, later Edison's partner
for a time. Lowrey went West to "Bleeding Kansas" with the first Governor,
Reeder, and both were active participants in the exciting scenes of the "Free
State" war until driven away in 1856, like many other free-soilers, by the
acts of the "Border Ruffian" legislature. Returning East, Mr. Lowrey took
up practice in New York, soon becoming eminent in his profession, and
upon the accession of William Orton to the presidency of the Western
Union Telegraph Company in 1866, he was appointed its general counsel,
the duties of which post he discharged for fifteen years. One of the great
cases in which he thus took a leading and distinguished part was that of the
quadruplex telegraph; and later he acted as legal adviser to Henry Villard in
his numerous grandiose enterprises. Lowrey thus came to know Edison, to
conceive an intense admiration for him, and to believe in his ability at a
time when others could not detect the fire of genius smouldering beneath
the modest exterior of a gaunt young operator slowly "finding himself." It
will be seen that Mr Lowrey was in a peculiarly advantageous position to
make his convictions about Edison felt, so that it was he and his friends
who rallied quickly to the new banner of discovery, and lent to the inventor
the aid that came at a critical period. In this connection it may be well to
quote an article that appeared at the time of Mr. Lowrey's death, in 1893:
"One of the most important services which Mr. Lowrey has ever performed
was in furnishing and procuring the necessary financial backing for Thomas
A. Edison in bringing out and perfecting his system of incandescent
lighting. With characteristic pertinacity, Mr. Lowrey stood by the inventor
through thick and thin, in spite of doubt, discouragement, and ridicule, until
at last success crowned his efforts. In all the litigation which has resulted
from the wide-spread infringements of the Edison patents, Mr. Lowrey has
ever borne the burden and heat of the day, and perhaps in no other field has
he so personally distinguished himself as in the successful advocacy of the
claims of Edison to the invention of the incandescent lamp and everything
'hereunto pertaining.'"
This was the man of whom Edison had necessarily to make a confidant
and adviser, and who supplied other things besides the legal direction and
financial alliance, by his knowledge of the world and of affairs. There were
many vital things to be done in the exploitation of the system that Edison
simply could not and would not do; but in Lowrey's savoir faire, ready wit
and humor, chivalry of devotion, graceful eloquence, and admirable
for a time. Lowrey went West to "Bleeding Kansas" with the first Governor,

that met the exigencies.
We are indebted to Mr. Insull for a graphic sketch of Edison at this
period, and of the conditions under which work was done and progress was
made: "I do not think I had any understanding with Edison when I first went
with him as to my duties. I did whatever he told me, and looked after all
kinds of affairs, from buying his clothes to financing his business. I used to
open the correspondence and answer it all, sometimes signing Edison's
name with my initial, and sometimes signing my own name. If the latter
course was pursued, and I was addressing a stranger, I would sign as
Edison's private secretary. I held his power of attorney, and signed his
checks. It was seldom that Edison signed a letter or check at this time. If he
wanted personally to send a communication to anybody, if it was one of his
close associates, it would probably be a pencil memorandum signed
'Edison.' I was a shorthand writer, but seldom took down from Edison's
dictation, unless it was on some technical subject that I did not understand. I
would go over the correspondence with Edison, sometimes making a
marginal note in shorthand, and sometimes Edison would make his own
notes on letters, and I would be expected to clean up the correspondence
with Edison's laconic comments as a guide as to the character of answer to
make. It was a very common thing for Edison to write the words 'Yes' or
'No,' and this would be all I had on which to base my answer. Edison
marginalized documents extensively. He had a wonderful ability in pointing
out the weak points of an agreement or a balance-sheet, all the while
protesting he was no lawyer or accountant; and his views were expressed in
very few words, but in a characteristic and emphatic manner.
"The first few months I was with Edison he spent most of the time in the
office at 65 Fifth Avenue. Then there was a great deal of trouble with the
life of the lamps there, and he disappeared from the office and spent his
time largely at Menlo Park. At another time there was a great deal of trouble
with some of the details of construction of the dynamos, and Edison spent a
lot of time at Goerck Street, which had been rapidly equipped with the idea
of turning out bi-polar dynamo-electric machines, direct-connected to the
engine, the first of which went to Paris and London, while the next were
installed in the old Pearl Street station of the Edison Electric Illuminating
Company of New York, just south of Fulton Street, on the west side of the
street. Edison devoted a great deal of his time to the engineering work in
that met the exigencies.

Page 249
connection with the laying out of the first incandescent electric-lighting
system in New York. Apparently at that time—between the end of 1881 and
spring of 1882—the most serious work was the manufacture and
installation of underground conductors in this territory. These conductors
were manufactured by the Electric Tube Company, which Edison controlled
in a shop at 65 Washington Street, run by John Kruesi. Half-round copper
conductors were used, kept in place relatively to each other and in the tube,
first of all by a heavy piece of cardboard, and later on by a rope; and then
put in a twenty-foot iron pipe; and a combination of asphaltum and linseed
oil was forced into the pipe for the insulation. I remember as a coincidence
that the building was only twenty feet wide. These lengths of conductors
were twenty feet six inches long, as the half-round coppers extended three
inches beyond the drag-ends of the lengths of pipe; and in one of the
operations we used to take the length of tubing out of the window in order
to turn it around. I was elected secretary of the Electric Tube Company, and
was expected to look after its finance; and it was in this position that my
long intimacy with John Kruesi started."
At this juncture a large part of the correspondence referred very naturally
to electric lighting, embodying requests for all kinds of information,
catalogues, prices, terms, etc.; and all these letters were turned over to the
lighting company by Edison for attention. The company was soon swamped
with propositions for sale of territorial rights and with other negotiations,
and some of these were accompanied by the offer of very large sums of
money. It was the beginning of the electric-light furor which soon rose to
sensational heights. Had the company accepted the cash offers from various
localities, it could have gathered several millions of dollars at once into its
treasury; but this was not at all in accord with Mr. Edison's idea, which was
to prove by actual experience the commercial value of the system, and then
to license central-station companies in large cities and towns, the parent
company taking a percentage of their capital for the license under the
Edison patents, and contracting also for the supply of apparatus, lamps, etc.
This left the remainder of the country open for the cash sale of plants
wherever requested. His counsels prevailed, and the wisdom of the policy
adopted was seen in the swift establishment of Edison companies in centres
of population both great and small, whose business has ever been a constant
and growing source of income for the parent manufacturing interests.

From first to last Edison has been an exponent and advocate of the
central-station idea of distribution now so familiar to the public mind, but
still very far from being carried out to its logical conclusion. In this
instance, demands for isolated plants for lighting factories, mills, mines,
hotels, etc., began to pour in, and something had to be done with them. This
was a class of plant which the inquirers desired to purchase outright and
operate themselves, usually because of remoteness from any possible
source of general supply of current. It had not been Edison's intention to
cater to this class of customer until his broad central-station plan had been
worked out, and he has always discouraged the isolated plant within the
limits of urban circuits; but this demand was so insistent it could not be
denied, and it was deemed desirable to comply with it at once, especially as
it was seen that the steady call for supplies and renewals would benefit the
new Edison manufacturing plants. After a very short trial, it was found
necessary to create a separate organization for this branch of the industry,
leaving the Edison Electric Light Company to continue under the original
plan of operation as a parent, patent-holding and licensing company.
Accordingly a new and distinct corporation was formed called the Edison
Company for Isolated Lighting, to which was issued a special license to sell
and operate plants of a self-contained character. As a matter of fact such
work began in advance of almost every other kind. A small plant using the
paper-carbon filament lamps was furnished by Edison at the earnest
solicitation of Mr. Henry Villard for the steamship Columbia, in 1879, and
it is amusing to note that Mr. Upton carried the lamps himself to the ship,
very tenderly and jealously, like fresh eggs, in a market-garden basket. The
installation was most successful. Another pioneer plant was that equipped
and started in January, 1881, for Hinds & Ketcham, a New York firm of
lithographers and color printers, who had previously been able to work only
by day, owing to difficulties in color-printing by artificial light. A year later
they said: "It is the best substitute for daylight we have ever known, and
almost as cheap."
Mr. Edison himself describes various instances in which the demand for
isolated plants had to be met: "One night at '65,'" he says, "James Gordon
Bennett came in. We were very anxious to get into a printing establishment.
I had caused a printer's composing case to be set up with the idea that if we
could get editors and publishers in to see it, we should show them the
advantages of the electric light. So ultimately Mr. Bennett came, and after

advantages of the electric light. So ultimately Mr. Bennett came, and after
Page 251
seeing the whole operation of everything, he ordered Mr. Howland, general
manager of the Herald, to light the newspaper offices up at once with
electricity."
Another instance of the same kind deals with the introduction of the light
for purely social purposes: "While at 65 Fifth Avenue," remarks Mr. Edison,
"I got to know Christian Herter, then the largest decorator in the United
States. He was a highly intellectual man, and I loved to talk to him. He was
always railing against the rich people, for whom he did work, for their poor
taste. One day Mr. W. H. Vanderbilt came to '65,' saw the light, and decided
that he would have his new house lighted with it. This was one of the big
'box houses' on upper Fifth Avenue. He put the whole matter in the hands of
his son-in-law, Mr. H. McK. Twombly, who was then in charge of the
telephone department of the Western Union. Twombly closed the contract
with us for a plant. Mr. Herter was doing the decoration, and it was
extraordinarily fine. After a while we got the engines and boilers and wires
all done, and the lights in position, before the house was quite finished, and
thought we would have an exhibit of the light. About eight o'clock in the
evening we lit up, and it was very good. Mr. Vanderbilt and his wife and
some of his daughters came in, and were there a few minutes when a fire
occurred. The large picture-gallery was lined with silk cloth interwoven
with fine metallic thread. In some manner two wires had got crossed with
this tinsel, which became red-hot, and the whole mass was soon afire. I
knew what was the matter, and ordered them to run down and shut off. It
had not burst into flame, and died out immediately. Mrs. Vanderbilt became
hysterical, and wanted to know where it came from. We told her we had the
plant in the cellar, and when she learned we had a boiler there she said she
would not occupy the house. She would not live over a boiler. We had to
take the whole installation out. The houses afterward went onto the New
York Edison system."
The art was, however, very crude and raw, and as there were no artisans
in existence as mechanics or electricians who had any knowledge of the
practice, there was inconceivable difficulty in getting such isolated plants
installed, as well as wiring the buildings in the district to be covered by the
first central station in New York. A night school was, therefore, founded at
Fifth Avenue, and was put in charge of Mr. E. H. Johnson, fresh from his
successes in England. The most available men for the purpose were, of
course, those who had been accustomed to wiring for the simpler electrical
manager of the Herald, to light the newspaper offices up at once with
electricity."

knew what was the matter, and ordered them to run down and shut off. It
had not burst into flame, and died out immediately. Mrs. Vanderbilt became
hysterical, and wanted to know where it came from. We told her we had the
plant in the cellar, and when she learned we had a boiler there she said she
would not occupy the house. She would not live over a boiler. We had to
take the whole installation out. The houses afterward went onto the New
York Edison system."
The art was, however, very crude and raw, and as there were no artisans
in existence as mechanics or electricians who had any knowledge of the
practice, there was inconceivable difficulty in getting such isolated plants
installed, as well as wiring the buildings in the district to be covered by the
first central station in New York. A night school was, therefore, founded at
Fifth Avenue, and was put in charge of Mr. E. H. Johnson, fresh from his
successes in England. The most available men for the purpose were, of
course, those who had been accustomed to wiring for the simpler electrical
Page 252
systems then in vogue—telephones, district-messenger calls, burglar
alarms, house annunciators, etc., and a number of these "wiremen" were
engaged and instructed patiently in the rudiments of the new art by means
of a blackboard and oral lessons. Students from the technical schools and
colleges were also eager recruits, for here was something that promised a
career, and one that was especially alluring to youth because of its novelty.
These beginners were also instructed in general engineering problems under
the guidance of Mr. C. L. Clarke, who was brought in from the Menlo Park
laboratory to assume charge of the engineering part of the company's
affairs. Many of these pioneer students and workmen became afterward
large and successful contractors, or have filled positions of distinction as
managers and superintendents of central stations. Possibly the electrical
industry may not now attract as much adventurous genius as it did then, for
automobiles, aeronautics, and other new arts have come to the front in a
quarter of a century to enlist the enthusiasm of a younger generation of
mercurial spirits; but it is certain that at the period of which we write,
Edison himself, still under thirty-five, was the centre of an extraordinary
group of men, full of effervescing and aspiring talent, to which he gave
glorious opportunity.
A very novel literary feature of the work was the issuance of a bulletin
devoted entirely to the Edison lighting propaganda. Nowadays the "house
organ," as it is called, has become a very hackneyed feature of industrial
development, confusing in its variety and volume, and a somewhat doubtful
adjunct to a highly perfected, widely circulating periodical technical press.
But at that time, 1882, the Bulletin of the Edison Electric Light Company,
published in ordinary 12mo form, was distinctly new in advertising and
possibly unique, as it is difficult to find anything that compared with it. The
Bulletin was carried on for some years, until its necessity was removed by
the development of other opportunities for reaching the public; and its
pages serve now as a vivid and lively picture of the period to which its
record applies. The first issue, of January 12, 1882, was only four pages, but
it dealt with the question of insurance; plants at Santiago, Chili, and Rio de
Janeiro; the European Company with 3,500,000 francs subscribed; the work
in Paris, London, Strasburg, and Moscow; the laying of over six miles of
street mains in New York; a patent decision in favor of Edison; and the size
of safety catch wire. By April of 1882, the Bulletin had attained the
respectable size of sixteen pages; and in December it was a portly magazine

respectable size of sixteen pages; and in December it was a portly magazine
Page 253
of forty-eight. Every item bears testimony to the rapid progress being made;
and by the end of 1882 it is seen that no fewer than 153 isolated Edison
plants had been installed in the United States alone, with a capacity of
29,192 lamps. Moreover, the New York central station had gone into
operation, starting at 3 P.M. on September 4, and at the close of 1882 it was
lighting 225 houses wired for about 5000 lamps. This epochal story will be
told in the next chapter. Most interesting are the Bulletin notes from
England, especially in regard to the brilliant exhibition given by Mr. E. H.
Johnson at the Crystal Palace, Sydenham, visited by the Duke and Duchess
of Edinburgh, twice by the Dukes of Westminster and Sutherland, by three
hundred members of the Gas Institute, and by innumerable delegations from
cities, boroughs, etc. Describing this before the Royal Society of Arts, Sir
W. H. Preece, F.R.S., remarked: "Many unkind things have been said of Mr.
Edison and his promises; perhaps no one has been severer in this direction
than myself. It is some gratification for me to announce my belief that he
has at last solved the problem he set himself to solve, and to be able to
describe to the Society the way in which he has solved it." Before the
exhibition closed it was visited by the Prince and Princess of Wales—now
the deceased Edward VII. and the Dowager Queen Alexandra—and the
Princess received from Mr. Johnson as a souvenir a tiny electric chandelier
fashioned like a bouquet of fern leaves and flowers, the buds being some of
the first miniature incandescent lamps ever made.
The first item in the first Bulletin dealt with the "Fire Question," and all
through the successive issues runs a series of significant items on the same
subject. Many of them are aimed at gas, and there are several grim
summaries of death and fires due to gas-leaks or explosions. A tendency
existed at the time to assume that electricity was altogether safe, while its
opponents, predicating their attacks on arc-lighting casualties, insisted it
was most dangerous. Edison's problem in educating the public was rather
difficult, for while his low-pressure, direct-current system has always been
absolutely without danger to life, there has also been the undeniable fact
that escaping electricity might cause a fire just as a leaky water-pipe can
flood a house. The important question had arisen, therefore, of satisfying
the fire underwriters as to the safety of the system. He had foreseen that
there would be an absolute necessity for special devices to prevent fires
from occurring by reason of any excess of current flowing in any circuit;
and several of his earliest detail lighting inventions deal with this subject.

The insurance underwriters of New York and other parts of the country gave
a great deal of time and study to the question through their most expert
representatives, with the aid of Edison and his associates, other electric-
light companies cooperating; and the knowledge thus gained was embodied
in insurance rules to govern wiring for electric lights, formulated during the
latter part of 1881, adopted by the New York Board of Fire Underwriters,
January 12, 1882, and subsequently endorsed by other boards in the various
insurance districts. Under temporary rulings, however, a vast amount of
work had already been done, but it was obvious that as the industry grew
there would be less and less possibility of supervision except through such
regulations, insisting upon the use of the best devices and methods. Indeed,
the direct superintendence soon became unnecessary, owing to the
increasing knowledge and greater skill acquired by the installing staff; and
this system of education was notably improved by a manual written by Mr.
Edison himself. Copies of this brochure are as scarce to-day as First Folio
Shakespeares, and command prices equal to those of other American first
editions. The little book is the only known incursion of its author into
literature, if we except the brief articles he has written for technical papers
and for the magazines. It contained what was at once a full, elaborate, and
terse explanation of a complete isolated plant, with diagrams of various
methods of connection and operation, and a carefully detailed description of
every individual part, its functions and its characteristics. The remarkable
success of those early years was indeed only achieved by following up with
Chinese exactness the minute and intimate methods insisted upon by Edison
as to the use of the apparatus and devices employed. It was a curious
example of establishing standard practice while changing with
kaleidoscopic rapidity all the elements involved. He was true to an ideal as
to the pole-star, but was incessantly making improvements in every
direction. With an iconoclasm that has often seemed ruthless and brutal he
did not hesitate to sacrifice older devices the moment a new one came in
sight that embodied a real advance in securing effective results. The process
is heroic but costly. Nobody ever had a bigger scrap-heap than Edison; but
who dare proclaim the process intrinsically wasteful if the losses occur in
the initial stages, and the economies in all the later ones?

With Edison in this introduction of his lighting system the method was
ruthless, but not reckless. At an early stage of the commercial development
a standardizing committee was formed, consisting of the heads of all the
Page 255
departments, and to this body was intrusted the task of testing and
criticising all existing and proposed devices, as well as of considering the
suggestions and complaints of workmen offered from time to time. This
procedure was fruitful in two principal results—the education of the whole
executive force in the technical details of the system; and a constant
improvement in the quality of the Edison installations; both contributing to
the rapid growth of the industry.
For many years Goerck Street played an important part in Edison's
affairs, being the centre of all his manufacture of heavy machinery. But it
was not in a desirable neighborhood, and owing to the rapid growth of the
business soon became disadvantageous for other reasons. Edison tells of his
frequent visits to the shops at night, with the escort of "Jim" Russell, a well-
known detective, who knew all the denizens of the place: "We used to go
out at night to a little, low place, an all-night house—eight feet wide and
twenty-two feet long—where we got a lunch at two or three o'clock in the
morning. It was the toughest kind of restaurant ever seen. For the clam
chowder they used the same four clams during the whole season, and the
average number of flies per pie was seven. This was by actual count."
As to the shops and the locality: "The street was lined with rather old
buildings and poor tenements. We had not much frontage. As our business
increased enormously, our quarters became too small, so we saw the district
Tammany leader and asked him if we could not store castings and other
things on the sidewalk. He gave us permission—told us to go ahead, and he
would see it was all right. The only thing he required for this was that when
a man was sent with a note from him asking us to give him a job, he was to
be put on. We had a hand-laborer foreman—'Big Jim'—a very powerful
Irishman, who could lift above half a ton. When one of the Tammany
aspirants appeared, he was told to go right to work at $1.50 per day. The
next day he was told off to lift a certain piece, and if the man could not lift
it he was discharged. That made the Tammany man all safe. Jim could pick
the piece up easily. The other man could not, and so we let him out. Finally
the Tammany leader called a halt, as we were running big engine lathes out
on the sidewalk, and he was afraid we were carrying it a little too far. The
lathes were worked right out in the street, and belted through the windows
of the shop."

At last it became necessary to move from Goerck Street, and Mr. Edison
gives a very interesting account of the incidents in connection with the
transfer of the plant to Schenectady, New York: "After our works at Goerck
Street got too small, we had labor troubles also. It seems I had rather a
socialistic strain in me, and I raised the pay of the workmen twenty-five
cents an hour above the prevailing rate of wages, whereupon Hoe &
Company, our near neighbors, complained at our doing this. I said I thought
it was all right. But the men, having got a little more wages, thought they
would try coercion and get a little more, as we were considered soft marks.
Whereupon they struck at a time that was critical. However, we were short
of money for pay-rolls; and we concluded it might not be so bad after all, as
it would give us a couple of weeks to catch up. So when the men went out
they appointed a committee to meet us; but for two weeks they could not
find us, so they became somewhat more anxious than we were. Finally they
said they would like to go back. We said all right, and back they went. It
was quite a novelty to the men not to be able to find us when they wanted
to; and they didn't relish it at all.
"What with these troubles and the lack of room, we decided to find a
factory elsewhere, and decided to try the locomotive works up at
Schenectady. It seems that the people there had had a falling out among
themselves, and one of the directors had started opposition works; but
before he had completed all the buildings and put in machinery some
compromise was made, and the works were for sale. We bought them very
reasonably and moved everything there. These works were owned by me
and my assistants until sold to the Edison General Electric Company. At one
time we employed several thousand men; and since then the works have
been greatly expanded.
"At these new works our orders were far in excess of our capital to
handle the business, and both Mr. Insull and I were afraid we might get into
trouble for lack of money. Mr. Insull was then my business manager,
running the whole thing; and, therefore, when Mr. Henry Villard and his
syndicate offered to buy us out, we concluded it was better to be sure than
be sorry; so we sold out for a large sum. Villard was a very aggressive man
with big ideas, but I could never quite understand him. He had no sense of
humor. I remember one time we were going up on the Hudson River boat to
inspect the works, and with us was Mr. Henderson, our chief engineer, who
was certainly the best raconteur of funny stories I ever knew. We sat at the

disconcerted he had to give it up. It was the same way with Gould. In the

situations; but Gould never smiled once."

consolidation of the immediate Edison manufacturing interests in electric
light and power, with a capitalization of $12,000,000, now a relatively
modest sum; but in those days the amount was large, and the combination
caused a great deal of newspaper comment as to such a coinage of brain
power. The next step came with the creation of the great General Electric

from twenty to twenty-five thousand people.

CHAPTER XVI
THE FIRST EDISON CENTRAL STATION
A NOTED inventor once said at the end of a lifetime of fighting to
defend his rights, that he found there were three stages in all great
inventions: the first, in which people said the thing could not be done; the
second, in which they said anybody could do it; and the third, in which they
said it had always been done by everybody. In his central-station work
Edison has had very much this kind of experience; for while many of his
opponents came to acknowledge the novelty and utility of his plans, and
gave him unstinted praise, there are doubtless others who to this day profess
to look upon him merely as an adapter. How different the view of so
eminent a scientist as Lord Kelvin was, may be appreciated from his remark
when in later years, in reply to the question why some one else did not
invent so obvious and simple a thing as the Feeder System, he said: "The
only answer I can think of is that no one else was Edison."
Undaunted by the attitude of doubt and the predictions of impossibility,
Edison had pushed on until he was now able to realize all his ideas as to the
establishment of a central station in the work that culminated in New York
City in 1882. After he had conceived the broad plan, his ambition was to
create the initial plant on Manhattan Island, where it would be convenient
of access for watching its operation, and where the demonstration of its
practicability would have influence in financial circles. The first intention
was to cover a district extending from Canal Street on the north to Wall
Street on the south; but Edison soon realized that this territory was too
extensive for the initial experiment, and he decided finally upon the district
included between Wall, Nassau, Spruce, and Ferry streets, Peck Slip and the
East River, an area nearly a square mile in extent. One of the preliminary
steps taken to enable him to figure on such a station and system was to have
men go through this district on various days and note the number of gas jets
burning at each hour up to two or three o'clock in the morning. The next
step was to divide the region into a number of sub-districts and institute a
house-to-house canvass to ascertain precisely the data and conditions

burning at each hour up to two or three o'clock in the morning. The next
step was to divide the region into a number of sub-districts and institute a
house-to-house canvass to ascertain precisely the data and conditions
Page 259
pertinent to the project. When the canvass was over, Edison knew exactly
how many gas jets there were in every building in the entire district, the
average hours of burning, and the cost of light; also every consumer of
power, and the quantity used; every hoistway to which an electric motor
could be applied; and other details too numerous to mention, such as related
to the gas itself, the satisfaction of the customers, and the limitations of day
and night demand. All this information was embodied graphically in large
maps of the district, by annotations in colored inks; and Edison thus could
study the question with every detail before him. Such a reconnaissance, like
that of a coming field of battle, was invaluable, and may help give a further
idea of the man's inveterate care for the minutiae of things.
The laboratory note-books of this period—1878-80, more particularly—
show an immense amount of calculation by Edison and his chief
mathematician, Mr. Upton, on conductors for the distribution of current
over large areas, and then later in the district described. With the results of
this canvass before them, the sizes of the main conductors to be laid
throughout the streets of this entire territory were figured, block by block;
and the results were then placed on the map. These data revealed the fact
that the quantity of copper required for the main conductors would be
exceedingly large and costly; and, if ever, Edison was somewhat dismayed.
But as usual this apparently insurmountable difficulty only spurred him on
to further effort. It was but a short time thereafter that he solved the knotty
problem by an invention mentioned in a previous chapter. This is known as
the "feeder and main" system, for which he signed the application for a
patent on August 4, 1880. As this invention effected a saving of seven-
eighths of the cost of the chief conductors in a straight multiple arc system,
the mains for the first district were refigured, and enormous new maps were
made, which became the final basis of actual installation, as they were
subsequently enlarged by the addition of every proposed junction-box,
bridge safety-catch box, and street-intersection box in the whole area.
When this patent, after protracted fighting, was sustained by Judge Green
in 1893, the Electrical Engineer remarked that the General Electric
Company "must certainly feel elated" because of its importance; and the
journal expressed its fear that although the specifications and claims related
only to the maintenance of uniform pressure of current on lighting circuits,
the owners might naturally seek to apply it also to feeders used in the
electric-railway work already so extensive. At this time, however, the patent
how many gas jets there were in every building in the entire district, the
average hours of burning, and the cost of light; also every consumer of
power, and the quantity used; every hoistway to which an electric motor
could be applied; and other details too numerous to mention, such as related
to the gas itself, the satisfaction of the customers, and the limitations of day
and night demand. All this information was embodied graphically in large
maps of the district, by annotations in colored inks; and Edison thus could
study the question with every detail before him. Such a reconnaissance, like
that of a coming field of battle, was invaluable, and may help give a further
idea of the man's inveterate care for the minutiae of things.

Page 260
had only about a year of life left, owing to the expiration of the
corresponding English patent. The fact that thirteen years had elapsed gives
a vivid idea of the ordeal involved in sustaining a patent and the injustice to
the inventor, while there is obviously hardship to those who cannot tell
from any decision of the court whether they are infringing or not. It is
interesting to note that the preparation for hearing this case in New Jersey
was accompanied by models to show the court exactly the method and its
economy, as worked out in comparison with what is known as the "tree
system" of circuits—the older alternative way of doing it. As a basis of
comparison, a district of thirty-six city blocks in the form of a square was
assumed. The power station was placed at the centre of the square; each
block had sixteen consumers using fifteen lights each. Conductors were run
from the station to supply each of the four quarters of the district with light.
In one example the "feeder" system was used; in the other the "tree." With
these models were shown two cubes which represented one one-hundredth
of the actual quantity of copper required for each quarter of the district by
the two-wire tree system as compared with the feeder system under like
conditions. The total weight of copper for the four quarter districts by the
tree system was 803,250 pounds, but when the feeder system was used it
was only 128,739 pounds! This was a reduction from $23.24 per lamp for
copper to $3.72 per lamp. Other models emphasized this extraordinary
contrast. At the time Edison was doing this work on economizing in
conductors, much of the criticism against him was based on the assumed
extravagant use of copper implied in the obvious "tree" system, and it was
very naturally said that there was not enough copper in the world to supply
his demands. It is true that the modern electrical arts have been a great
stimulator of copper production, now taking a quarter of all made; yet
evidently but for such inventions as this such arts could not have come into
existence at all, or else in growing up they would have forced copper to
starvation prices. [11]
[Footnote 11: For description of feeder patent see
Appendix.]
It should be borne in mind that from the outset Edison had determined
upon installing underground conductors as the only permanent and
satisfactory method for the distribution of current from central stations in
cities; and that at Menlo Park he laid out and operated such a system with
corresponding English patent. The fact that thirteen years had elapsed gives

It should be borne in mind that from the outset Edison had determined
upon installing underground conductors as the only permanent and
satisfactory method for the distribution of current from central stations in
cities; and that at Menlo Park he laid out and operated such a system with
Page 261
about four hundred and twenty-five lamps. The underground system there
was limited to the immediate vicinity of the laboratory and was somewhat
crude, as well as much less complicated than would be the network of over
eighty thousand lineal feet, which he calculated to be required for the
underground circuits in the first district of New York City. At Menlo Park
no effort was made for permanency; no provision was needed in regard to
occasional openings of the street for various purposes; no new customers
were to be connected from time to time to the mains, and no repairs were
within contemplation. In New York the question of permanency was of
paramount importance, and the other contingencies were sure to arise as
well as conditions more easy to imagine than to forestall. These problems
were all attacked in a resolute, thoroughgoing manner, and one by one
solved by the invention of new and unprecedented devices that were
adequate for the purposes of the time, and which are embodied in apparatus
of slight modification in use up to the present day.
Just what all this means it is hard for the present generation to imagine.
New York and all the other great cities in 1882, and for some years
thereafter, were burdened and darkened by hideous masses of overhead
wires carried on ugly wooden poles along all the main thoroughfares. One
after another rival telegraph and telephone, stock ticker, burglar-alarm, and
other companies had strung their circuits without any supervision or
restriction; and these wires in all conditions of sag or decay ramified and
crisscrossed in every direction, often hanging broken and loose-ended for
months, there being no official compulsion to remove any dead wire. None
of these circuits carried dangerous currents; but the introduction of the arc
light brought an entirely new menace in the use of pressures that were even
worse than the bully of the West who "kills on sight," because this kindred
peril was invisible, and might lurk anywhere. New poles were put up, and
the lighting circuits on them, with but a slight insulation of cotton
impregnated with some "weather-proof" compound, straggled all over the
city exposed to wind and rain and accidental contact with other wires, or
with the metal of buildings. So many fatalities occurred that the insulated
wire used, called "underwriters," because approved by the insurance bodies,
became jocularly known as "undertakers," and efforts were made to
improve its protective qualities. Then came the overhead circuits for

proportionately larger. There were no wires underground. Morse had tried
that at the very beginning of electrical application, in telegraphy, and all
agreed that renewals of the experiment were at once costly and foolish. At
last, in cities like New York, what may be styled generically the "overhead
system" of wires broke down under its own weight; and various methods of
underground conductors were tried, hastened in many places by the
chopping down of poles and wires as the result of some accident that stirred
the public indignation. One typical tragic scene was that in New York,
where, within sight of the City Hall, a lineman was killed at his work on the
arc light pole, and his body slowly roasted before the gaze of the excited
populace, which for days afterward dropped its silver and copper coin into
the alms-box nailed to the fatal pole for the benefit of his family. Out of all
this in New York came a board of electrical control, a conduit system, and
in the final analysis the Public Service Commission, that is credited to
Governor Hughes as the furthest development of utility corporation control.
The "road to yesterday" back to Edison and his insistence on
underground wires is a long one, but the preceding paragraph traces it. Even
admitting that the size and weight of his low-tension conductors
necessitated putting them underground, this argues nothing against the
propriety and sanity of his methods. He believed deeply and firmly in the
analogy between electrical supply and that for water and gas, and pointed to
the trite fact that nobody hoisted the water and gas mains into the air on
stilts, and that none of the pressures were inimical to human safety. The arc-
lighting methods were unconsciously and unwittingly prophetic of the
latter-day long-distance transmissions at high pressure that, electrically,
have placed the energy of Niagara at the command of Syracuse and Utica,
and have put the power of the falling waters of the Sierras at the disposal of
San Francisco, two hundred miles away. But within city limits overhead
wires, with such space-consuming potentials, are as fraught with
mischievous peril to the public as the dynamite stored by a nonchalant
contractor in the cellar of a schoolhouse. As an offset, then, to any tendency
to depreciate the intrinsic value of Edison's lighting work, let the claim be
here set forth modestly and subject to interference, that he was the father of
underground wires in America, and by his example outlined the policy now
dominant in every city of the first rank. Even the comment of a cynic in
regard to electrical development may be accepted: "Some electrical

companies wanted all the air; others apparently had use for all the water;
Edison only asked for the earth."
The late Jacob Hess, a famous New York Republican politician, was a
member of the commission appointed to put the wires underground in New
York City, in the "eighties." He stated that when the commission was
struggling with the problem, and examining all kinds of devices and plans,
patented and unpatented, for which fabulous sums were often asked, the
body turned to Edison in its perplexity and asked for advice. Edison said:
"All you have to do, gentlemen, is to insulate your wires, draw them
through the cheapest thing on earth—iron pipe—run your pipes through
channels or galleries under the street, and you've got the whole thing done."
This was practically the system adopted and in use to this day. What
puzzled the old politician was that Edison would accept nothing for his
advice.
Another story may also be interpolated here as to the underground work
done in New York for the first Edison station. It refers to the "man higher
up," although the phrase had not been coined in those days of lower public
morality. That a corporation should be "held up" was accepted
philosophically by the corporation as one of the unavoidable incidents of its
business; and if the corporation "got back" by securing some privilege
without paying for it, the public was ready to condone if not applaud. Public
utilities were in the making, and no one in particular had a keen sense of
what was right or what was wrong, in the hard, practical details of their
development. Edison tells this illuminating story: "When I was laying tubes
in the streets of New York, the office received notice from the
Commissioner of Public Works to appear at his office at a certain hour. I
went up there with a gentleman to see the Commissioner, H. O. Thompson.
On arrival he said to me: 'You are putting down these tubes. The
Department of Public Works requires that you should have five inspectors
to look after this work, and that their salary shall be $5 per day, payable at
the end of each week. Good-morning.' I went out very much crestfallen,
thinking I would be delayed and harassed in the work which I was anxious
to finish, and was doing night and day. We watched patiently for those
inspectors to appear. The only appearance they made was to draw their pay
Saturday afternoon."
Edison only asked for the earth."

Just before Christmas in 1880—December 17—as an item for the silk
stocking of Father Knickerbocker—the Edison Electric Illuminating
Company of New York was organized. In pursuance of the policy adhered
to by Edison, a license was issued to it for the exclusive use of the system in
that territory—Manhattan Island—in consideration of a certain sum of
money and a fixed percentage of its capital in stock for the patent rights.
Early in 1881 it was altogether a paper enterprise, but events moved swiftly
as narrated already, and on June 25, 1881, the first "Jumbo" prototype of the
dynamo-electric machines to generate current at the Pearl Street station was
put through its paces before being shipped to Paris to furnish new
sensations to the flaneur of the boulevards. A number of the Edison officers
and employees assembled at Goerck Street to see this "gigantic" machine
go into action, and watched its performance with due reverence all through
the night until five o'clock on Sunday morning, when it respected the
conventionalities by breaking a shaft and suspending further tests. After this
dynamo was shipped to France, and its successors to England for the
Holborn Viaduct plant, Edison made still further improvements in design,
increasing capacity and economy, and then proceeded vigorously with six
machines for Pearl Street.
An ideal location for any central station is at the very centre of the
district served. It may be questioned whether it often goes there. In the New
York first district the nearest property available was a double building at
Nos. 255 and 257 Pearl Street, occupying a lot so by 100 feet. It was four
stories high, with a fire-wall dividing it into two equal parts. One of these
parts was converted for the uses of the station proper, and the other was
used as a tube-shop by the underground construction department, as well as
for repair-shops, storage, etc. Those were the days when no one built a new
edifice for station purposes; that would have been deemed a fantastic
extravagance. One early station in New York for arc lighting was an old
soap-works whose well-soaked floors did not need much additional grease
to render them choice fuel for the inevitable flames. In this Pearl Street
instance, the building, erected originally for commercial uses, was quite
incapable of sustaining the weight of the heavy dynamos and steam-engines
to be installed on the second floor; so the old flooring was torn out and a
new one of heavy girders supported by stiff columns was substituted. This
heavy construction, more familiar nowadays, and not unlike the supporting
metal structure of the Manhattan Elevated road, was erected independent of
stocking of Father Knickerbocker—the Edison Electric Illuminating
Company of New York was organized. In pursuance of the policy adhered
to by Edison, a license was issued to it for the exclusive use of the system in

the enclosing walls, and occupied the full width of 257 Pearl Street, and
about three-quarters of its depth. This change in the internal arrangements
did not at all affect the ugly external appearance, which did little to suggest
the stately and ornate stations since put up by the New York Edison
Company, the latest occupying whole city blocks.
Of this episode Edison gives the following account: "While planning for
my first New York station—Pearl Street—of course, I had no real estate,
and from lack of experience had very little knowledge of its cost in New
York; so I assumed a rather large, liberal amount of it to plan my station on.
It occurred to me one day that before I went too far with my plans I had
better find out what real estate was worth. In my original plan I had 200 by
200 feet. I thought that by going down on a slum street near the water-front
I would get some pretty cheap property. So I picked out the worst
dilapidated street there was, and found I could only get two buildings, each
25 feet front, one 100 feet deep and the other 85 feet deep. I thought about
$10,000 each would cover it; but when I got the price I found that they
wanted $75,000 for one and $80,000 for the other. Then I was compelled to
change my plans and go upward in the air where real estate was cheap. I
cleared out the building entirely to the walls and built my station of
structural ironwork, running it up high."
Into this converted structure was put the most complete steam plant
obtainable, together with all the mechanical and engineering adjuncts
bearing upon economical and successful operation. Being in a narrow street
and a congested district, the plant needed special facilities for the handling
of coal and ashes, as well as for ventilation and forced draught. All of these
details received Mr. Edison's personal care and consideration on the spot, in
addition to the multitude of other affairs demanding his thought. Although
not a steam or mechanical engineer, his quick grasp of principles and
omnivorous reading had soon supplied the lack of training; nor had he
forgotten the practical experience picked up as a boy on the locomotives of
the Grand Trunk road. It is to be noticed as a feature of the plant, in
common with many of later construction, that it was placed well away from
the water's edge, and equipped with non-condensing engines; whereas the
modern plant invariably seeks the bank of a river or lake for the purpose of
a generous supply of water for its condensing engines or steam-turbines.
These are among the refinements of practice coincidental with the advance
of the art.

At the award of the John Fritz gold medal in April, 1909, to Charles T.
Porter for his work in advancing the knowledge of steam-engineering, and
for improvements in engine construction, Mr. Frank J. Sprague spoke on
behalf of the American Institute of Electrical Engineers of the debt of
electricity to the high-speed steam-engine. He recalled the fact that at the
French Exposition of 1867 Mr. Porter installed two Porter-Allen engines to
drive electric alternating-current generators for supplying current to
primitive lighthouse apparatus. While the engines were not directly coupled
to the dynamos, it was a curious fact that the piston speeds and number of
revolutions were what is common to-day in isolated direct-coupled plants.
In the dozen years following Mr. Porter built many engines with certain
common characteristics—i.e., high piston speed and revolutions, solid
engine bed, and babbitt-metal bearings; but there was no electric driving
until 1880, when Mr. Porter installed a high-speed engine for Edison at his
laboratory in Menlo Park. Shortly after this he was invited to construct for
the Edison Pearl Street station the first of a series of engines for so-called
"steam-dynamos," each independently driven by a direct-coupled engine.
Mr. Sprague compared the relations thus established between electricity and
the high-speed engine not to those of debtor and creditor, but rather to those
of partners—an industrial marriage—one of the most important in the
engineering world. Here were two machines destined to be joined together,
economizing space, enhancing economy, augmenting capacity, reducing
investment, and increasing dividends.
While rapid progress was being made in this and other directions, the
wheels of industry were humming merrily at the Edison Tube Works, for
over fifteen miles of tube conductors were required for the district, besides
the boxes to connect the network at the street intersections, and the
hundreds of junction boxes for taking the service conductors into each of
the hundreds of buildings. In addition to the immense amount of money
involved, this specialized industry required an enormous amount of
experiment, as it called for the development of an entirely new art. But with
Edison's inventive fertility—if ever there was a cross-fertilizer of
mechanical ideas it is he—and with Mr. Kruesi's never-failing patience and
perseverance applied to experiment and evolution, rapid progress was
made. A franchise having been obtained from the city, the work of laying
the underground conductors began in the late fall of 1881, and was pushed
with almost frantic energy. It is not to be supposed, however, that the

Edison tube system had then reached a finality of perfection in the eyes of
its inventor. In his correspondence with Kruesi, as late as 1887, we find
Edison bewailing the inadequacy of the insulation of the conductors under
twelve hundred volts pressure, as for example: "Dear Kruesi,—There is
nothing wrong with your present compound. It is splendid. The whole
trouble is air-bubbles. The hotter it is poured the greater the amount of air-
bubbles. At 212 it can be put on rods and there is no bubble. I have a man
experimenting and testing all the time. Until I get at the proper method of
pouring and getting rid of the air-bubbles, it will be waste of time to
experiment with other asphalts. Resin oil distils off easily. It may answer,
but paraffine or other similar substances must be put in to prevent
brittleness, One thing is certain, and that is, everything must be poured in
layers, not only the boxes, but the tubes. The tube itself should have a thin
coating. The rope should also have a coating. The rods also. The whole lot,
rods and rope, when ready for tube, should have another coat, and then be
placed in tube and filled. This will do the business." Broad and large as a
continent in his ideas, if ever there was a man of finical fussiness in
attention to detail, it is Edison. A letter of seven pages of about the same
date in 1887 expatiates on the vicious troubles caused by the air-bubble, and
remarks with fine insight into the problems of insulation and the idea of
layers of it: "Thus you have three separate coatings, and it is impossible an
air-hole in one should match the other."
To a man less thorough and empirical in method than Edison, it would
have been sufficient to have made his plans clear to associates or
subordinates and hold them responsible for accurate results. No such
vicarious treatment would suit him, ready as he has always been to share
the work where he could give his trust. In fact he realized, as no one else
did at this stage, the tremendous import of this novel and comprehensive
scheme for giving the world light; and he would not let go, even if busy to
the breaking-point. Though plunged in a veritable maelstrom of new and
important business interests, and though applying for no fewer than eighty-
nine patents in 1881, all of which were granted, he superintended on the
spot all this laying of underground conductors for the first district. Nor did
he merely stand around and give orders. Day and night he actually worked
in the trenches with the laborers, amid the dirt and paving-stones and hurry-
burly of traffic, helping to lay the tubes, filling up junction-boxes, and
taking part in all the infinite detail. He wanted to know for himself how

things went, why for some occult reason a little change was necessary, what
improvement could be made in the material. His hours of work were not
regulated by the clock, but lasted until he felt the need of a little rest. Then
he would go off to the station building in Pearl Street, throw an overcoat on
a pile of tubes, lie down and sleep for a few hours, rising to resume work
with the first gang. There was a small bedroom on the third floor of the
station available for him, but going to bed meant delay and consumed time.
It is no wonder that such impatience, such an enthusiasm, drove the work
forward at a headlong pace.
Edison says of this period: "When we put down the tubes in the lower
part of New York, in the streets, we kept a big stock of them in the cellar of
the station at Pearl Street. As I was on all the time, I would take a nap of an
hour or so in the daytime—any time—and I used to sleep on those tubes in
the cellar. I had two Germans who were testing there, and both of them died
of diphtheria, caught in the cellar, which was cold and damp. It never
affected me."
It is worth pausing just a moment to glance at this man taking a fitful rest
on a pile of iron pipe in a dingy building. His name is on the tip of the
world's tongue. Distinguished scientists from every part of Europe seek him
eagerly. He has just been decorated and awarded high honors by the French
Government. He is the inventor of wonderful new apparatus, and the
exploiter of novel and successful arts. The magic of his achievements and
the rumors of what is being done have caused a wild drop in gas securities,
and a sensational rise in his own electric-light stock from $100 to $3500 a
share. Yet these things do not at all affect his slumber or his democratic
simplicity, for in that, as in everything else, he is attending strictly to
business, "doing the thing that is next to him."
Part of the rush and feverish haste was due to the approach of frost,
which, as usual in New York, suspended operations in the earth; but the
laying of the conductors was resumed promptly in the spring of 1882; and
meantime other work had been advanced. During the fall and winter months
two more "Jumbo" dynamos were built and sent to London, after which the
construction of six for New York was swiftly taken in hand. In the month of
May three of these machines, each with a capacity of twelve hundred
incandescent lamps, were delivered at Pearl Street and assembled on the
second floor. On July 5th—owing to the better opportunity for ceaseless toil
improvement could be made in the material. His hours of work were not

Page 269
given by a public holiday—the construction of the operative part of the
station was so far completed that the first of the dynamos was operated
under steam; so that three days later the satisfactory experiment was made
of throwing its flood of electrical energy into a bank of one thousand lamps
on an upper floor. Other tests followed in due course. All was excitement.
The field-regulating apparatus and the electrical-pressure indicator—first of
its kind—were also tested, and in turn found satisfactory. Another vital test
was made at this time—namely, of the strength of the iron structure itself on
which the plant was erected. This was done by two structural experts; and
not till he got their report as to ample factors of safety was Edison reassured
as to this detail.
A remark of Edison, familiar to all who have worked with him, when it is
reported to him that something new goes all right and is satisfactory from
all points of view, is: "Well, boys, now let's find the bugs," and the hunt for
the phylloxera begins with fiendish, remorseless zest. Before starting the
plant for regular commercial service, he began personally a series of
practical experiments and tests to ascertain in advance what difficulties
would actually arise in practice, so that he could provide remedies or
preventives. He had several cots placed in the adjoining building, and he
and a few of his most strenuous assistants worked day and night, leaving
the work only for hurried meals and a snatch of sleep. These crucial tests,
aiming virtually to break the plant down if possible within predetermined
conditions, lasted several weeks, and while most valuable in the
information they afforded, did not hinder anything, for meantime customers'
premises throughout the district were being wired and supplied with lamps
and meters.
On Monday, September 4, 1882, at 3 o'clock, P.M., Edison realized the
consummation of his broad and original scheme. The Pearl Street station
was officially started by admitting steam to the engine of one of the
"Jumbos," current was generated, turned into the network of underground
conductors, and was transformed into light by the incandescent lamps that
had thus far been installed. This date and event may properly be regarded as
historical, for they mark the practical beginning of a new art, which in the
intervening years has grown prodigiously, and is still increasing by leaps
and bounds.

Everything worked satisfactorily in the main. There were a few
mechanical and engineering annoyances that might naturally be expected to
arise in a new and unprecedented enterprise; but nothing of sufficient
moment to interfere with the steady and continuous supply of current to
customers at all hours of the day and night. Indeed, once started, this station
was operated uninterruptedly for eight years with only insignificant
stoppage.
It will have been noted by the reader that there was nothing to indicate
rashness in starting up the station, as only one dynamo was put in operation.
Within a short time, however, it was deemed desirable to supply the
underground network with more current, as many additional customers had
been connected and the demand for the new light was increasing very
rapidly. Although Edison had successfully operated several dynamos in
multiple arc two years before—i.e., all feeding current together into the
same circuits—there was not, at this early period of experience, any
absolute certainty as to what particular results might occur upon the
throwing of the current from two or more such massive dynamos into a
great distributing system. The sequel showed the value of Edison's cautious
method in starting the station by operating only a single unit at first.
He decided that it would be wise to make the trial operation of a second
"Jumbo" on a Sunday, when business houses were closed in the district,
thus obviating any danger of false impressions in the public mind in the
event of any extraordinary manifestations. The circumstances attending the
adding of a second dynamo are thus humorously described by Edison: "My
heart was in my mouth at first, but everything worked all right.... Then we
started another engine and threw them in parallel. Of all the circuses since
Adam was born, we had the worst then! One engine would stop, and the
other would run up to about a thousand revolutions, and then they would
see-saw. The trouble was with the governors. When the circus commenced,
the gang that was standing around ran out precipitately, and I guess some of
them kept running for a block or two. I grabbed the throttle of one engine,
and E. H. Johnson, who was the only one present to keep his wits, caught
hold of the other, and we shut them off." One of the "gang" that ran, but, in
this case, only to the end of the room, afterward said: "At the time it was a
terrifying experience, as I didn't know what was going to happen. The
engines and dynamos made a horrible racket, from loud and deep groans to
a hideous shriek, and the place seemed to be filled with sparks and flames

Page 271
of all colors. It was as if the gates of the infernal regions had been suddenly
opened."
This trouble was at once attacked by Edison in his characteristic and
strenuous way. The above experiment took place between three and four
o'clock on a Sunday afternoon, and within a few hours he had gathered his
superintendent and men of the machine-works and had them at work on a
shafting device that he thought would remedy the trouble. He says: "Of
course, I discovered that what had happened was that one set was running
the other as a motor. I then put up a long shaft, connecting all the governors
together, and thought this would certainly cure the trouble; but it didn't. The
torsion of the shaft was so great that one governor still managed to get
ahead of the others. Well, it was a serious state of things, and I worried over
it a lot. Finally I went down to Goerck Street and got a piece of shafting and
a tube in which it fitted. I twisted the shafting one way and the tube the
other as far as I could, and pinned them together. In this way, by straining
the whole outfit up to its elastic limit in opposite directions, the torsion was
practically eliminated, and after that the governors ran together all right."
Edison realized, however, that in commercial practice this was only a
temporary expedient, and that a satisfactory permanence of results could
only be attained with more perfect engines that could be depended upon for
close and simple regulation. The engines that were made part of the first
three "Jumbos" placed in the station were the very best that could be
obtained at the time, and even then had been specially designed and built
for the purpose. Once more quoting Edison on this subject: "About that
time" (when he was trying to run several dynamos in parallel in the Pearl
Street station) "I got hold of Gardiner C. Sims, and he undertook to build an
engine to run at three hundred and fifty revolutions and give one hundred
and seventy-five horse-power. He went back to Providence and set to work,
and brought the engine back with him to the shop. It worked only a few
minutes when it busted. That man sat around that shop and slept in it for
three weeks, until he got his engine right and made it work the way he
wanted it to. When he reached this period I gave orders for the engine-
works to run night and day until we got enough engines, and when all was
ready we started the engines. Then everything worked all right.... One of
these engines that Sims built ran twenty-four hours a day, three hundred and
sixty-five days in the year, for over a year before it stopped." [12]

[Footnote 12: We quote the following interesting notes of
Mr. Charles L. Clarke on the question of see-sawing, or
"hunting," as it was afterward termed:
"In the Holborn Viaduct station the difficulty of 'hunting' was not
experienced. At the time the 'Jumbos' were first operated in multiple arc,
April 8, 1882, one machine was driven by a Porter-Allen engine, and the
other by an Armington & Sims engine, and both machines were on a solid
foundation. At the station at Milan, Italy, the first 'Jumbos' operated in
multiple arc were driven by Porter-Allen engines, and dash-pots were
applied to the governors. These machines were also upon a solid
foundation, and no trouble was experienced.
"At the Pearl Street station, however, the machines were supported upon
long iron floor-beams, and at the high speed of 350 revolutions per minute,
considerable vertical vibration was given to the engines. And the writer is
inclined to the opinion that this vibration, acting in the same direction as the
action of gravitation, which was one of the two controlling forces in the
operation of the Porter-Allen governor, was the primary cause of the
'hunting.' In the Armington & Sims engine the controlling forces in the
operation of the governor were the centrifugal force of revolving weights,
and the opposing force of compressed springs, and neither the action of
gravitation nor the vertical vibrations of the engine could have any sensible
effect upon the governor."]
The Pearl Street station, as this first large plant was called, made rapid
and continuous growth in its output of electric current. It started, as we have
said, on September 4, 1882, supplying about four hundred lights to a
comparatively small number of customers. Among those first supplied was
the banking firm of Drexel, Morgan & Company, corner of Broad and Wall
streets, at the outermost limits of the system. Before the end of December of
the same year the light had so grown in favor that it was being supplied to
over two hundred and forty customers whose buildings were wired for over
five thousand lamps. By this time three more "Jumbos" had been added to
the plant. The output from this time forward increased steadily up to the
spring of 1884, when the demands of the station necessitated the installation
of two additional "Jumbos" in the adjoining building, which, with the
venous improvements that had been made in the mean time, gave the station
a capacity of over eleven thousand lamps actually in service at any one
time.

operation of the Porter-Allen governor, was the primary cause of the
'hunting.' In the Armington & Sims engine the controlling forces in the
operation of the governor were the centrifugal force of revolving weights,
and the opposing force of compressed springs, and neither the action of
gravitation nor the vertical vibrations of the engine could have any sensible
effect upon the governor."]
The Pearl Street station, as this first large plant was called, made rapid
and continuous growth in its output of electric current. It started, as we have
said, on September 4, 1882, supplying about four hundred lights to a
comparatively small number of customers. Among those first supplied was
the banking firm of Drexel, Morgan & Company, corner of Broad and Wall
streets, at the outermost limits of the system. Before the end of December of
the same year the light had so grown in favor that it was being supplied to
over two hundred and forty customers whose buildings were wired for over
five thousand lamps. By this time three more "Jumbos" had been added to
the plant. The output from this time forward increased steadily up to the
spring of 1884, when the demands of the station necessitated the installation
of two additional "Jumbos" in the adjoining building, which, with the
venous improvements that had been made in the mean time, gave the station
a capacity of over eleven thousand lamps actually in service at any one
time.

During the first three months of operating the Pearl Street station light
was supplied to customers without charge. Edison had perfect confidence in
his meters, and also in the ultimate judgment of the public as to the
superiority of the incandescent electric light as against other illuminants. He
realized, however, that in the beginning of the operation of an entirely novel
plant there was ample opportunity for unexpected contingencies, although
the greatest care had been exercised to make everything as perfect as
possible. Mechanical defects or other unforeseen troubles in any part of the
plant or underground system might arise and cause temporary stoppages of
operation, thus giving grounds for uncertainty which would create a feeling
of public distrust in the permanence of the supply of light.
As to the kind of mishap that was wont to occur, Edison tells the
following story: "One afternoon, after our Pearl Street station started, a
policeman rushed in and told us to send an electrician at once up to the
corner of Ann and Nassau streets—some trouble. Another man and I went
up. We found an immense crowd of men and boys there and in the adjoining
streets—a perfect jam. There was a leak in one of our junction-boxes, and
on account of the cellars extending under the street, the top soil had become
insulated. Hence, by means of this leak powerful currents were passing
through this thin layer of moist earth. When a horse went to pass over it he
would get a very severe shock. When I arrived I saw coming along the
street a ragman with a dilapidated old horse, and one of the boys told him to
go over on the other side of the road—which was the place where the
current leaked. When the ragman heard this he took that side at once. The
moment the horse struck the electrified soil he stood straight up in the air,
and then reared again; and the crowd yelled, the policeman yelled; and the
horse started to run away. This continued until the crowd got so serious that
the policeman had to clear it out; and we were notified to cut the current off.
We got a gang of men, cut the current off for several junction-boxes, and
fixed the leak. One man who had seen it came to me next day and wanted
me to put in apparatus for him at a place where they sold horses. He said he
could make a fortune with it, because he could get old nags in there and
make them act like thoroughbreds."
So well had the work been planned and executed, however, that nothing
happened to hinder the continuous working of the station and the supply of
light to customers. Hence it was decided in December, 1882, to begin
charging a price for the service, and, accordingly, Edison electrolytic meters
was supplied to customers without charge. Edison had perfect confidence in

light to customers. Hence it was decided in December, 1882, to begin
charging a price for the service, and, accordingly, Edison electrolytic meters
Page 274
were installed on the premises of each customer then connected. The first
bill for lighting, based upon the reading of one of these meters, amounted to
$50.40, and was collected on January 18, 1883, from the Ansonia Brass and
Copper Company, 17 and 19 Cliff Street. Generally speaking, customers
found that their bills compared fairly with gas bills for corresponding
months where the same amount of light was used, and they paid promptly
and cheerfully, with emphatic encomiums of the new light. During
November, 1883, a little over one year after the station was started, bills for
lighting amounting to over $9000 were collected.
An interesting story of meter experience in the first few months of
operation of the Pearl Street station is told by one of the "boys" who was
then in position to know the facts; "Mr. J. P. Morgan, whose firm was one of
the first customers, expressed to Mr. Edison some doubt as to the accuracy
of the meter. The latter, firmly convinced of its correctness, suggested a
strict test by having some cards printed and hung on each fixture at Mr.
Morgan's place. On these cards was to be noted the number of lamps in the
fixture, and the time they were turned on and off each day for a month. At
the end of that time the lamp-hours were to be added together by one of the
clerks and figured on a basis of a definite amount per lamp-hour, and
compared with the bill that would be rendered by the station for the
corresponding period. The results of the first month's test showed an
apparent overcharge by the Edison company. Mr. Morgan was exultant,
while Mr. Edison was still confident and suggested a continuation of the
test. Another month's trial showed somewhat similar results. Mr. Edison
was a little disturbed, but insisted that there was a mistake somewhere. He
went down to Drexel, Morgan & Company's office to investigate, and, after
looking around, asked when the office was cleaned out. He was told it was
done at night by the janitor, who was sent for, and upon being interrogated
as to what light he used, said that he turned on a central fixture containing
about ten lights. It came out that he had made no record of the time these
lights were in use. He was told to do so in future, and another month's test
was made. On comparison with the company's bill, rendered on the meter-
reading, the meter came within a few cents of the amount computed from
the card records, and Mr. Morgan was completely satisfied of the accuracy
of the meter."
It is a strange but not extraordinary commentary on the perversity of
human nature and the lack of correct observation, to note that even after the
bill for lighting, based upon the reading of one of these meters, amounted to
$50.40, and was collected on January 18, 1883, from the Ansonia Brass and

human nature and the lack of correct observation, to note that even after the
Page 275
Pearl Street station had been in actual operation twenty-four hours a day for
nearly three months, there should still remain an attitude of "can't be done."
That such a scepticism still obtained is evidenced by the public prints of the
period. Edison's electric-light system and his broad claims were freely
discussed and animadverted upon at the very time he was demonstrating
their successful application. To show some of the feeling at the time, we
reproduce the following letter, which appeared November 29, 1882:
"To the Editor of the Sun:
"SIR,—In reading the discussions relative to the Pearl Street station of
the Edison light, I have noted that while it is claimed that there is scarcely
any loss from leakage of current, nothing is said about the loss due to the
resistance of the long circuits. I am informed that this is the secret of the
failure to produce with the power in position a sufficient amount of current
to run all the lamps that have been put up, and that while six, and even
seven, lights to the horse-power may be produced from an isolated plant,
the resistance of the long underground wires reduces this result in the above
case to less than three lights to the horse-power, thus making the cost of
production greatly in excess of gas. Can the Edison company explain this?
'INVESTIGATOR'."
This was one of the many anonymous letters that had been written to the
newspapers on the subject, and the following reply by the Edison company
was printed December 3, 1882:
"To the Editor of the Sun:
"SIR,—'Investigator' in Wednesday's Sun, says that the Edison company
is troubled at its Pearl Street station with a 'loss of current, due to the
resistance of the long circuits'; also that, whereas Edison gets 'six or even
seven lights to the horse-power in isolated plants, the resistance of the long
underground wires reduces that result in the Pearl Street station to less than
three lights to the horse-power.' Both of these statements are false. As
regards loss due to resistance, there is a well-known law for determining it,
based on Ohm's law. By use of that law we knew in advance, that is to say,
when the original plans for the station were drawn, just what this loss would
be, precisely the same as a mechanical engineer when constructing a mill
with long lines of shafting can forecast the loss of power due to friction.
The practical result in the Pearl Street station has fully demonstrated the
correctness of our estimate thus made in advance. As regards our getting
nearly three months, there should still remain an attitude of "can't be done."

The practical result in the Pearl Street station has fully demonstrated the

only three lights per horse-power, our station has now been running three
months, without stopping a moment, day or night, and we invariably get
over six lamps per horse-power, or substantially the same as we do in our
isolated plants. We are now lighting one hundred and ninety-three
buildings, wired for forty-four hundred lamps, of which about two-thirds
are in constant use, and we are adding additional houses and lamps daily.
These figures can be verified at the office of the Board of Underwriters,
where certificates with full details permitting the use of our light are filed
by their own inspector. To light these lamps we run from one to three
dynamos, according to the lamps in use at any given time, and we shall start
additional dynamos as fast as we can connect more buildings. Neither as
regards the loss due to resistance, nor as regards the number of lamps per
horse-power, is there the slightest trouble or disappointment on the part of
our company, and your correspondent is entirely in error is assuming that
there is. Let me suggest that if 'Investigator' really wishes to investigate, and
is competent and willing to learn the exact facts, he can do so at this office,
where there is no mystery of concealment, but, on the contrary, a strong
desire to communicate facts to intelligent inquirers. Such a method of
investigating must certainly be more satisfactory to one honestly seeking
knowledge than that of first assuming an error as the basis of a question,
and then demanding an explanation.

Viewed from the standpoint of over twenty-seven years later, the wisdom
and necessity of answering anonymous newspaper letters of this kind might
be deemed questionable, but it must be remembered that, although the Pearl
Street station was working successfully, and Edison's comprehensive plans
were abundantly vindicated, the enterprise was absolutely new and only just
stepping on the very threshold of commercial exploitation. To enter in and
possess the land required the confidence of capital and the general public.
Hence it was necessary to maintain a constant vigilance to defeat the
insidious attacks of carping critics and others who would attempt to injure

was not a single electrical instrument in the whole station—not a voltmeter
Page 277
or an ammeter! Nor was there a central switchboard! Each dynamo had its
own individual control switch. The feeder connections were all at the front
of the building, and the general voltage control apparatus was on the floor
above. An automatic pressure indicator had been devised and put in
connection with the main circuits. It consisted, generally speaking, of an
electromagnet with relays connecting with a red and a blue lamp. When the
electrical pressure was normal, neither lamp was lighted; but if the
electromotive force rose above a predetermined amount by one or two
volts, the red lamp lighted up, and the attendant at the hand-wheel of the
field regulator inserted resistance in the field circuit, whereas, if the blue
lamp lighted, resistance was cut out until the pressure was raised to normal.
Later on this primitive indicator was supplanted by the "Bradley Bridge," a
crude form of the "Howell" pressure indicators, which were subsequently
used for many years in the Edison stations.

persons. We cannot close this chapter, however, without mention of the fate
of the Pearl Street station, which continued in successful commercial
operation until January 2, 1890, when it was partially destroyed by fire. All
the "Jumbos" were ruined, excepting No. 9, which is still a venerated relic
in the possession of the New York Edison Company. Luckily, the boilers
were unharmed. Belt-driven generators and engines were speedily installed,
and the station was again in operation in a few days. The uninjured
"Jumbo," No. 9, again continued to perform its duty. But in the words of
Mr. Charles L. Clarke, "the glory of the old Pearl Street station, unique in
bearing the impress of Mr. Edison's personality, and, as it were, constructed
with his own hands, disappeared in the flame and smoke of that Thursday
morning fire."
The few days' interruption of the service was the only serious one that
has taken place in the history of the New York Edison Company from
September 4, 1882, to the present date. The Pearl Street station was
operated for some time subsequent to the fire, but increasing demands in the
mean time having led to the construction of other stations, the mains of the

The prophetic insight into the magnitude of central-station lighting that
Edison had when he was still experimenting on the incandescent lamp over
thirty years ago is a little less than astounding, when it is so amply verified
in the operations of the New York Edison Company (the successor of the
Edison Electric Illuminating Company of New York) and many others. At
the end of 1909 the New York Edison Company alone was operating
twenty-eight stations and substations, having a total capacity of 159,500
kilowatts. Connected with its lines were approximately 85,000 customers
wired for 3,813,899 incandescent lamps and nearly 225,000 horse-power
through industrial electric motors connected with the underground service.
A large quantity of electrical energy is also supplied for heating and
cooking, charging automobiles, chemical and plating work, and various
other uses.

CHAPTER XVII
OTHER EARLY STATIONS—THE METER
WE have now seen the Edison lighting system given a complete,
convincing demonstration in Paris, London, and New York; and have noted
steps taken for its introduction elsewhere on both sides of the Atlantic. The
Paris plant, like that at the Crystal Palace, was a temporary exhibit. The
London plant was less temporary, but not permanent, supplying before it
was torn out no fewer than three thousand lamps in hotels, churches, stores,
and dwellings in the vicinity of Holborn Viaduct. There Messrs. Johnson
and Hammer put into practice many of the ideas now standard in the art,
and secured much useful data for the work in New York, of which the story
has just been told.
As a matter of fact the first Edison commercial station to be operated in
this country was that at Appleton, Wisconsin, but its only serious claim to
notice is that it was the initial one of the system driven by water-power. It
went into service August 15, 1882, about three weeks before the Pearl
Street station. It consisted of one small dynamo of a capacity of two
hundred and eighty lights of 10 c.p. each, and was housed in an
unpretentious wooden shed. The dynamo-electric machine, though small,
was robust, for under all the varying speeds of water-power, and the
vicissitudes of the plant to which it, belonged, it continued in active use
until 1899—seventeen years.
Edison was from the first deeply impressed with the possibilities of
water-power, and, as this incident shows, was prompt to seize such a very
early opportunity. But his attention was in reality concentrated closely on
the supply of great centres of population, a task which he then felt might
well occupy his lifetime; and except in regard to furnishing isolated plants
he did not pursue further the development of hydro-electric stations. That
was left to others, and to the application of the alternating current, which
has enabled engineers to harness remote powers, and, within thoroughly
economical limits, transmit thousands of horse-power as much as two
hundred miles at pressures of 80,000 and 100,000 volts. Owing to his

economical limits, transmit thousands of horse-power as much as two
hundred miles at pressures of 80,000 and 100,000 volts. Owing to his
Page 281
insistence on low pressure, direct current for use in densely populated
districts, as the only safe and truly universal, profitable way of delivering
electrical energy to the consumers, Edison has been frequently spoken of as
an opponent of the alternating current. This does him an injustice. At the
time a measure was before the Virginia legislature, in 1890, to limit the
permissible pressures of current so as to render it safe, he said: "You want
to allow high pressure wherever the conditions are such that by no possible
accident could that pressure get into the houses of the consumers; you want
to give them all the latitude you can." In explaining this he added: "Suppose
you want to take the falls down at Richmond, and want to put up a water-
power? Why, if we erect a station at the falls, it is a great economy to get it
up to the city. By digging a cheap trench and putting in an insulated cable,
and connecting such station with the central part of Richmond, having the
end of the cable come up into the station from the earth and there connected
with motors, the power of the falls would be transmitted to these motors. If
now the motors were made to run dynamos conveying low-pressure
currents to the public, there is no possible way whereby this high-pressure
current could get to the public." In other words, Edison made the sharp
fundamental distinction between high pressure alternating current for
transmission and low pressure direct current for distribution; and this is
exactly the practice that has been adopted in all the great cities of the
country to-day. There seems no good reason for believing that it will
change. It might perhaps have been altogether better for Edison, from the
financial standpoint, if he had not identified himself so completely with one
kind of current, but that made no difference to him, as it was a matter of
conviction; and Edison's convictions are granitic. Moreover, this
controversy over the two currents, alternating and direct, which has become
historical in the field of electricity—and is something like the "irrepressible
conflict" we heard of years ago in national affairs—illustrates another
aspect of Edison's character. Broad as the prairies and free in thought as the
winds that sweep them, he is idiosyncratically opposed to loose and
wasteful methods, to plans of empire that neglect the poor at the gate.
Everything he has done has been aimed at the conservation of energy, the
contraction of space, the intensification of culture. Burbank and his tribe
represent in the vegetable world, Edison in the mechanical. Not only has he
developed distinctly new species, but he has elucidated the intensive art of
getting $1200 out of an electrical acre instead of $12—a manured market-
districts, as the only safe and truly universal, profitable way of delivering
electrical energy to the consumers, Edison has been frequently spoken of as
an opponent of the alternating current. This does him an injustice. At the
time a measure was before the Virginia legislature, in 1890, to limit the
permissible pressures of current so as to render it safe, he said: "You want
to allow high pressure wherever the conditions are such that by no possible
accident could that pressure get into the houses of the consumers; you want
to give them all the latitude you can." In explaining this he added: "Suppose
you want to take the falls down at Richmond, and want to put up a water-
power? Why, if we erect a station at the falls, it is a great economy to get it
up to the city. By digging a cheap trench and putting in an insulated cable,
and connecting such station with the central part of Richmond, having the
end of the cable come up into the station from the earth and there connected
with motors, the power of the falls would be transmitted to these motors. If
now the motors were made to run dynamos conveying low-pressure
currents to the public, there is no possible way whereby this high-pressure
current could get to the public." In other words, Edison made the sharp
fundamental distinction between high pressure alternating current for
transmission and low pressure direct current for distribution; and this is
exactly the practice that has been adopted in all the great cities of the
country to-day. There seems no good reason for believing that it will
change. It might perhaps have been altogether better for Edison, from the
financial standpoint, if he had not identified himself so completely with one
kind of current, but that made no difference to him, as it was a matter of
conviction; and Edison's convictions are granitic. Moreover, this

garden inside London and a ten-bushel exhausted wheat farm outside
Lawrence, Kansas, being the antipodes of productivity—yet very far short
of exemplifying the difference of electrical yield between an acre of
territory in Edison's "first New York district" and an acre in some small
town.
Edison's lighting work furnished an excellent basis—in fact, the only one
—for the development of the alternating current now so generally employed
in central-station work in America; and in the McGraw Electrical Directory
of April, 1909, no fewer than 4164 stations out of 5780 reported its use.
When the alternating current was introduced for practical purposes it was
not needed for arc lighting, the circuit for which, from a single dynamo,
would often be twenty or thirty miles in length, its current having a pressure
of not less than five or six thousand volts. For some years it was not found
feasible to operate motors on alternating-current circuits, and that reason
was often urged against it seriously. It could not be used for electroplating
or deposition, nor could it charge storage batteries, all of which are easily
within the ability of the direct current. But when it came to be a question of
lighting a scattered suburb, a group of dwellings on the outskirts, a remote
country residence or a farm-house, the alternating current, in all elements
save its danger, was and is ideal. Its thin wires can be carried cheaply over
vast areas, and at each local point of consumption the transformer of size
exactly proportioned to its local task takes the high-voltage transmission
current and lowers its potential at a ratio of 20 or 40 to 1, for use in
distribution and consumption circuits. This evolution has been quite
distinct, with its own inventors like Gaulard and Gibbs and Stanley, but
came subsequent to the work of supplying small, dense areas of population;
the art thus growing from within, and using each new gain as a means for
further achievement.
Nor was the effect of such great advances as those made by Edison
limited to the electrical field. Every department of mechanics was
stimulated and benefited to an extraordinary degree. Copper for the circuits
was more highly refined than ever before to secure the best conductivity,
and purity was insisted on in every kind of insulation. Edison was intolerant
of sham and shoddy, and nothing would satisfy him that could not stand
cross-examination by microscope, test-tube, and galvanometer. It was,
perhaps, the steam-engine on which the deepest imprint for good was made,
referred to already in the remarks of Mr. F. J. Sprague in the preceding
Lawrence, Kansas, being the antipodes of productivity—yet very far short
of exemplifying the difference of electrical yield between an acre of
territory in Edison's "first New York district" and an acre in some small

chapter, but best illustrated in the perfection of the modern high-speed
engine of the Armington & Sims type. Unless he could secure an engine of
smoother running and more exactly governed and regulated than those
available for his dynamo and lamp, Edison realized that he would find it
almost impossible to give a steady light. He did not want his customers to
count the heart-beats of the engine in the flicker of the lamp. Not a single
engine was even within gunshot of the standard thus set up, but the
emergency called forth its man in Gardiner C. Sims, a talented draughtsman
and designer who had been engaged in locomotive construction and in the
engineering department of the United States Navy. He may be quoted as to
what happened: "The deep interest, financial and moral, and friendly
backing I received from Mr. Edison, together with valuable suggestions,
enabled me to bring out the engine; as I was quite alone in the world—poor
—I had found a friend who knew what he wanted and explained it clearly.
Mr. Edison was a leader far ahead of the time. He compelled the design of
the successful engine.
"Our first engine compelled the inventing and making of a suitable
engine indicator to indicate it—the Tabor. He obtained the desired speed
and load with a friction brake; also regulator of speed; but waited for an
indicator to verify it. Then again there was no known way to lubricate an
engine for continuous running, and Mr. Edison informed me that as a
marine engine started before the ship left New York and continued running
until it reached its home port, so an engine for his purposes must produce
light at all times. That was a poser to me, for a five-hours' run was about all
that had been required up to that time.
"A day or two later Mr. Edison inquired: 'How far is it from here to
Lawrence; it is a long walk, isn't it?' 'Yes, rather.' He said: 'Of course you
will understand I meant without oil.' To say I was deeply perplexed does not
express my feelings. We were at the machine works, Goerck Street. I started
for the oil-room, when, about entering, I saw a small funnel lying on the
floor. It had been stepped on and flattened. I took it up, and it had solved the
engine-oiling problem—and my walk to Lawrence like a tramp actor's was
off! The eccentric strap had a round glass oil-cup with a brass base that
screwed into the strap. I took it off, and making a sketch, went to Dave
Cunningham, having the funnel in my hand to illustrate what I wanted
made. I requested him to make a sheet-brass oil-cup and solder it to the base
I had. He did so. I then had a standard made to hold another oil-cup, so as to
engine of the Armington & Sims type. Unless he could secure an engine of

which is now universally used."
It is needless to say that in due course the engine builders of the United
States developed a variety of excellent prime movers for electric-light and
power plants, and were grateful to the art from which such a stimulus came
to their industry; but for many years one never saw an Edison installation
without expecting to find one or more Armington & Sims high-speed
engines part of it. Though the type has gone out of existence, like so many
other things that are useful in their day and generation, it was once a very
vital part of the art, and one more illustration of that intimate manner in
which the advances in different fields of progress interact and co-operate.
Edison had installed his historic first great central-station system in New
York on the multiple arc system covered by his feeder and main invention,
which resulted in a notable saving in the cost of conductors as against a
straight two-wire system throughout of the "tree" kind. He soon foresaw
that still greater economy would be necessary for commercial success not
alone for the larger territory opening, but for the compact districts of large
cities. Being firmly convinced that there was a way out, he pushed aside a
mass of other work, and settled down to this problem, with the result that on
November 20, 1882, only two months after current had been sent out from
Pearl Street, he executed an application for a patent covering what is now
known as the "three-wire system." It has been universally recognized as one
of the most valuable inventions in the history of the lighting art. [13] Its use
resulted in a saving of over 60 per cent. of copper in conductors, figured on
the most favorable basis previously known, inclusive of those calculated
under his own feeder and main system. Such economy of outlay being
effected in one of the heaviest items of expense in central-station
construction, it was now made possible to establish plants in towns where
the large investment would otherwise have been quite prohibitive. The
invention is in universal use today, alike for direct and for alternating
current, and as well in the equipment of large buildings as in the distribution
system of the most extensive central-station networks. One cannot imagine
the art without it.

The strong position held by the Edison system, under the strenuous
competition that was already springing up, was enormously improved by
the introduction of the three-wire system; and it gave an immediate impetus
to incandescent lighting. Desiring to put this new system into practical use
promptly, and receiving applications for licenses from all over the country,
Edison selected Brockton, Massachusetts, and Sunbury, Pennsylvania, as
the two towns for the trial. Of these two Brockton required the larger plant,
but with the conductors placed underground. It was the first to complete its
arrangements and close its contract. Mr. Henry Villard, it will be
remembered, had married the daughter of Garrison, the famous abolitionist,
and it was through his relationship with the Garrison family that Brockton
came to have the honor of exemplifying so soon the principles of an entirely
new art. Sunbury, however, was a much smaller installation, employed
overhead conductors, and hence was the first to "cross the tape." It was
specially suited for a trial plant also, in the early days when a yield of six or
eight lamps to the horse-power was considered subject for congratulation.
The town being situated in the coal region of Pennsylvania, good coal could
then be obtained there at seventy-five cents a ton.
The Sunbury generating plant consisted of an Armington & Sims engine
driving two small Edison dynamos having a total capacity of about four
hundred lamps of 16 c.p. The indicating instruments were of the crudest
construction, consisting of two voltmeters connected by "pressure wires" to
the centre of electrical distribution. One ammeter, for measuring the
quantity of current output, was interpolated in the "neutral bus" or third-
wire return circuit to indicate when the load on the two machines was out of
balance. The circuits were opened and closed by means of about half a
dozen roughly made plug-switches. [14] The "bus-bars" to receive the
current from the dynamos were made of No. 000 copper line wire,
straightened out and fastened to the wooden sheathing of the station by iron
staples without any presence to insulation. Commenting upon this Mr. W. S.
Andrews, detailed from the central staff, says: "The interior winding of the
Sunbury station, including the running of two three-wire feeders the entire
length of the building from back to front, the wiring up of the dynamos and
switchboard and all instruments, together with bus-bars, etc.—in fact, all
labor and material used in the electrical wiring installation—amounted to
the sum of $90. I received a rather sharp letter from the New York office
expostulating for this EXTRAVAGANT EXPENDITURE, and stating that

the introduction of the three-wire system; and it gave an immediate impetus

great economy must be observed in future!" The street conductors were of
the overhead pole-line construction, and were installed by the construction
company that had been organized by Edison to build and equip central
stations. A special type of street pole had been devised by him for the three-
wire system.
[Footnote 14: By reason of the experience gained at this
station through the use of these crude plug-switches, Mr.
Edison started a competition among a few of his assistants
to devise something better. The result was the invention of
a "breakdown" switch by Mr. W. S. Andrews, which was
accepted by Mr. Edison as the best of the devices suggested,
and was developed and used for a great many years
afterward.]
Supplementing the story of Mr. Andrews is that of Lieut. F. J. Sprague,
who also gives a curious glimpse of the glorious uncertainties and
vicissitudes of that formative period. Mr. Sprague served on the jury at the
Crystal Palace Exhibition with Darwin's son—the present Sir Horace—and
after the tests were ended left the Navy and entered Edison's service at the
suggestion of Mr. E. H. Johnson, who was Edison's shrewd recruiting
sergeant in those days: "I resigned sooner than Johnson expected, and he
had me on his hands. Meanwhile he had called upon me to make a report of
the three-wire system, known in England as the Hopkinson, both Dr. John
Hopkinson and Mr. Edison being independent inventors at practically the
same time. I reported on that, left London, and landed in New York on the
day of the opening of the Brooklyn Bridge in 1883—May 24—with a year's
leave of absence.
"I reported at the office of Mr. Edison on Fifth Avenue and told him I had
seen Johnson. He looked me over and said: 'What did he promise you?' I
replied: 'Twenty-five hundred dollars a year.' He did not say much, but
looked it. About that time Mr. Andrews and I came together. On July 2d of
that year we were ordered to Sunbury, and to be ready to start the station on
the fourth. The electrical work had to be done in forty-eight hours! Having
travelled around the world, I had cultivated an indifference to any special
difficulties of that kind. Mr. Andrews and I worked in collaboration until the
night of the third. I think he was perhaps more appreciative than I was of
the discipline of the Edison Construction Department, and thought it would
be well for us to wait until the morning of the fourth before we started up. I
said we were sent over to get going, and insisted on starting up on the night

of the third. We had an Armington & Sims engine with sight-feed oiler. I
had never seen one, and did not know how it worked, with the result that we
soon burned up the babbitt metal in the bearings and spent a good part of
the night getting them in order. The next day Mr. Edison, Mr. Insull, and the
chief engineer of the construction department appeared on the scene and
wanted to know what had happened. They found an engine somewhat loose
in the bearings, and there followed remarks which would not look well in
print. Andrews skipped from under; he obeyed orders; I did not. But the
plant ran, and it was the first three-wire station in this country."
Seen from yet another angle, the worries of this early work were not
merely those of the men on the "firing line." Mr. Insull, in speaking of this
period, says: "When it was found difficult to push the central-station
business owing to the lack of confidence in its financial success, Edison
decided to go into the business of promoting and constructing central-
station plants, and he formed what was known as the Thomas A. Edison
Construction Department, which he put me in charge of. The organization
was crude, the steam-engineering talent poor, and owing to the
impossibility of getting any considerable capital subscribed, the plants were
put in as cheaply as possible. I believe that this construction department was
unkindly named the 'Destruction Department.' It served its purpose; never
made any money; and I had the unpleasant task of presiding at its
obsequies."
On July 4th the Sunbury plant was put into commercial operation by
Edison, and he remained a week studying its conditions and watching for
any unforeseen difficulty that might arise. Nothing happened, however, to
interfere with the successful running of the station, and for twenty years
thereafter the same two dynamos continued to furnish light in Sunbury.
They were later used as reserve machines, and finally, with the engine,
retired from service as part of the "Collection of Edisonia"; but they remain
in practically as good condition as when installed in 1883.
Sunbury was also provided with the first electro-chemical meters used in
the United States outside New York City, so that it served also to accentuate
electrical practice in a most vital respect—namely, the measurement of the
electrical energy supplied to customers. At this time and long after, all arc
lighting was done on a "flat rate" basis. The arc lamp installed outside a
customer's premises, or in a circuit for public street lighting, burned so
had never seen one, and did not know how it worked, with the result that we
soon burned up the babbitt metal in the bearings and spent a good part of
the night getting them in order. The next day Mr. Edison, Mr. Insull, and the

many hours nightly, so many nights in the month; and was paid for at that
rate, subject to rebate for hours when the lamp might be out through
accident. The early arc lamps were rated to require 9 to 10 amperes of
current, at 45 volts pressure each, receiving which they were estimated to
give 2000 c.p., which was arrived at by adding together the light found at
four different positions, so that in reality the actual light was about 500 c.p.
Few of these data were ever actually used, however; and it was all more or
less a matter of guesswork, although the central-station manager, aiming to
give good service, would naturally see that the dynamos were so operated
as to maintain as steadily as possible the normal potential and current. The
same loose methods applied to the early attempts to use electric motors on
arc-lighting circuits, and contracts were made based on the size of the
motor, the width of the connecting belt, or the amount of power the
customer thought he used—never on the measurement of the electrical
energy furnished him.
Here again Edison laid the foundation of standard practice. It is true that
even down to the present time the flat rate is applied to a great deal of
incandescent lighting, each lamp being charged for individually according
to its probable consumption during each month. This may answer, perhaps,
in a small place where the manager can gauge pretty closely from actual
observation what each customer does; but even then there are elements of
risk and waste; and obviously in a large city such a method would soon be
likely to result in financial disaster to the plant. Edison held that the
electricity sold must be measured just like gas or water, and he proceeded to
develop a meter. There was infinite scepticism around him on the subject,
and while other inventors were also giving the subject their thought, the
public took it for granted that anything so utterly intangible as electricity,
that could not be seen or weighed, and only gave secondary evidence of
itself at the exact point of use, could not be brought to accurate registration.
The general attitude of doubt was exemplified by the incident in Mr. J. P.
Morgan's office, noted in the last chapter. Edison, however, had satisfied
himself that there were various ways of accomplishing the task, and had
determined that the current should be measured on the premises of every
consumer. His electrolytic meter was very successful, and was of
widespread use in America and in Europe until the perfection of mechanical
meters by Elihu Thomson and others brought that type into general
acceptance. Hence the Edison electrolytic meter is no longer used, despite
rate, subject to rebate for hours when the lamp might be out through

Page 289
its excellent qualities. Houston & Kennelly in their Electricity in Everyday
Life sum the matter up as follows: "The Edison chemical meter is capable
of giving fair measurements of the amount of current passing. By reason,
however, of dissatisfaction caused from the inability of customers to read
the indications of the meter, it has in later years, to a great extent, been
replaced by registering meters that can be read by the customer."
The principle employed in the Edison electrolytic meter is that which
exemplifies the power of electricity to decompose a chemical substance. In
other words it is a deposition bath, consisting of a glass cell in which two
plates of chemically pure zinc are dipped in a solution of zinc sulphate.
When the lights or motors in the circuit are turned on, and a certain definite
small portion of the current is diverted to flow through the meter, from the
positive plate to the negative plate, the latter increases in weight by
receiving a deposit of metallic zinc; the positive plate meantime losing in
weight by the metal thus carried away from it. This difference in weight is a
very exact measure of the quantity of electricity, or number of ampere-
hours, that have, so to speak, passed through the cell, and hence of the
whole consumption in the circuit. The amount thus due from the customer
is ascertained by removing the cell, washing and drying the plates, and
weighing them in a chemical balance. Associated with this simple form of
apparatus were various ingenious details and refinements to secure
regularity of operation, freedom from inaccuracy, and immunity from such
tampering as would permit theft of current or damage. As the freezing of
the zinc sulphate solution in cold weather would check its operation, Edison
introduced, for example, into the meter an incandescent lamp and a
thermostat so arranged that when the temperature fell to a certain point, or
rose above another point, it was cut in or out; and in this manner the meter
could be kept from freezing. The standard Edison meter practice was to
remove the cells once a month to the meter-room of the central-station
company for examination, another set being substituted. The meter was
cheap to manufacture and install, and not at all liable to get out of order.
In December, 1888, Mr. W. J. Jenks read an interesting paper before the
American Institute of Electrical Engineers on the six years of practical
experience had up to that time with the meter, then more generally in use
than any other. It appears from the paper that twenty-three Edison stations
were then equipped with 5187 meters, which were relied upon for billing
the monthly current consumption of 87,856 lamps and 350 motors of 1000

horse-power total. This represented about 75 per cent. of the entire lamp
capacity of the stations. There was an average cost per lamp for meter
operation of twenty-two cents a year, and each meter took care of an
average of seventeen lamps. It is worthy of note, as to the promptness with
which the Edison stations became paying properties, that four of the
metered stations were earning upward of 15 per cent. on their capital stock;
three others between 8 and 10 per cent.; eight between 5 and 8 per cent.; the
others having been in operation too short a time to show definite results,
although they also went quickly to a dividend basis. Reports made in the
discussion at the meeting by engineers showed the simplicity and success of
the meter. Mr. C. L. Edgar, of the Boston Edison system, stated that he had
800 of the meters in service cared for by two men and three boys, the latter
employed in collecting the meter cells; the total cost being perhaps $2500 a
year. Mr. J. W. Lieb wrote from Milan, Italy, that he had in use on the
Edison system there 360 meters ranging from 350 ampere-hours per month
up to 30,000.
In this connection it should be mentioned that the Association of Edison
Illuminating Companies in the same year adopted resolutions unanimously
to the effect that the Edison meter was accurate, and that its use was not
expensive for stations above one thousand lights; and that the best financial
results were invariably secured in a station selling current by meter. Before
the same association, at its meeting in September, 1898, at Sault Ste. Marie,
Mr. C. S. Shepard read a paper on the meter practice of the New York
Edison Company, giving data as to the large number of Edison meters in
use and the transition to other types, of which to-day the company has
several on its circuits: "Until October, 1896, the New York Edison
Company metered its current in consumer's premises exclusively by the
old-style chemical meters, of which there were connected on that date 8109.
It was then determined to purchase no more." Mr. Shepard went on to state
that the chemical meters were gradually displaced, and that on September 1,
1898, there were on the system 5619 mechanical and 4874 chemical. The
meter continued in general service during 1899, and probably up to the
close of the century.
Mr. Andrews relates a rather humorous meter story of those early days:
"The meter man at Sunbury was a firm and enthusiastic believer in the
correctness of the Edison meter, having personally verified its reading many
times by actual comparison of lamp-hours. One day, on making out a

"The meter man at Sunbury was a firm and enthusiastic believer in the
correctness of the Edison meter, having personally verified its reading many
times by actual comparison of lamp-hours. One day, on making out a
Page 291
customer's bill, his confidence received a severe shock, for the meter
reading showed a consumption calling for a charge of over $200, whereas
he knew that the light actually used should not cost more than one-quarter
of that amount. He weighed and reweighed the meter plates, and pursued
every line of investigation imaginable, but all in vain. He felt he was up
against it, and that perhaps another kind of a job would suit him better.
Once again he went to the customer's meter to look around, when a small
piece of thick wire on the floor caught his eye. The problem was solved. He
suddenly remembered that after weighing the plates he went and put them
in the customer's meter; but the wire attached to one of the plates was too
long to go in the meter, and he had cut it off. He picked up the piece of
wire, took it to the station, weighed it carefully, and found that it accounted
for about $150 worth of electricity, which was the amount of the
difference."
Edison himself is, however, the best repertory of stories when it comes to
the difficulties of that early period, in connection with metering the current
and charging for it. He may be quoted at length as follows: "When we
started the station at Pearl Street, in September, 1882, we were not very
commercial. We put many customers on, but did not make out many bills.
We were more interested in the technical condition of the station than in the
commercial part. We had meters in which there were two bottles of liquid.
To prevent these electrolytes from freezing we had in each meter a strip of
metal. When it got very cold the metal would contract and close a circuit,
and throw a lamp into circuit inside the meter. The heat from this lamp
would prevent the liquid from freezing, so that the meter could go on doing
its duty. The first cold day after starting the station, people began to come in
from their offices, especially down in Front Street and Water Street, saying
the meter was on fire. We received numerous telephone messages about it.
Some had poured water on it, and others said: 'Send a man right up to put it
out.'
"After the station had been running several months and was technically a
success, we began to look after the financial part. We started to collect some
bills; but we found that our books were kept badly, and that the person in
charge, who was no business man, had neglected that part of it. In fact, he
did not know anything about the station, anyway. So I got the directors to
permit me to hire a man to run the station. This was Mr. Chinnock, who was
then superintendent of the Metropolitan Telephone Company of New York.

Page 292
I knew Chinnock to be square and of good business ability, and induced
him to leave his job. I made him a personal guarantee, that if he would take
hold of the station and put it on a commercial basis, and pay 5 per cent. on
$600,000, I would give him $10,000 out of my own pocket. He took hold,
performed the feat, and I paid him the $10,000. I might remark in this
connection that years afterward I applied to the Edison Electric Light
Company asking them if they would not like to pay me this money, as it
was spent when I was very hard up and made the company a success, and
was the foundation of their present prosperity. They said they 'were sorry'—
that is, 'Wall Street sorry'—and refused to pay it. This shows what a nice,
genial, generous lot of people they have over in Wall Street.
"Chinnock had a great deal of trouble getting the customers straightened
out. I remember one man who had a saloon on Nassau Street. He had had
his lights burning for two or three months. It was in June, and Chinnock put
in a bill for $20; July for $20; August about $28; September about $35. Of
course the nights were getting longer. October about $40; November about
$45. Then the man called Chinnock up. He said: 'I want to see you about
my electric-light bill.' Chinnock went up to see him. He said: 'Are you the
manager of this electric-light plant?' Chinnock said: 'I have the honor.'
'Well,' he said, my bill has gone from $20 up to $28, $35, $45. I want you to
understand, young fellow, that my limit is $60.'
"After Chinnock had had all this trouble due to the incompetency of the
previous superintendent, a man came in and said to him: 'Did Mr. Blank
have charge of this station?' 'Yes.' 'Did he know anything about running a
station like this?' Chinnock said: 'Does he KNOW anything about running a
station like this? No, sir. He doesn't even suspect anything.'
"One day Chinnock came to me and said: 'I have a new customer.' I said:
'What is it?' He said: 'I have a fellow who is going to take two hundred and
fifty lights.' I said: 'What for?' 'He has a place down here in a top loft, and
has got two hundred and fifty barrels of "rotgut" whiskey. He puts a light
down in the barrel and lights it up, and it ages the whiskey.' I met Chinnock
several weeks after, and said: 'How is the whiskey man getting along?' 'It's
all right; he is paying his bill. It fixes the whiskey and takes the shudder
right out of it.' Somebody went and took out a patent on this idea later.
"In the second year we put the Stock Exchange on the circuits of the
station, but were very fearful that there would be a combination of heavy
him to leave his job. I made him a personal guarantee, that if he would take

"In the second year we put the Stock Exchange on the circuits of the
station, but were very fearful that there would be a combination of heavy
Page 293
demand and a dark day, and that there would be an overloaded station. We
had an index like a steam-gauge, called an ampere-meter, to indicate the
amount of current going out. I was up at 65 Fifth Avenue one afternoon. A
sudden black cloud came up, and I telephoned to Chinnock and asked him
about the load. He said: 'We are up to the muzzle, and everything is running
all right.' By-and-by it became so thick we could not see across the street. I
telephoned again, and felt something would happen, but fortunately it did
not. I said to Chinnock: 'How is it now?' He replied: 'Everything is red-hot,
and the ampere-meter has made seventeen revolutions.'"
In 1883 no such fittings as "fixture insulators" were known. It was the
common practice to twine the electric wires around the disused gas-fixtures,
fasten them with tape or string, and connect them to lamp-sockets screwed
into attachments under the gas-burners—elaborated later into what was
known as the "combination fixture." As a result it was no uncommon thing
to see bright sparks snapping between the chandelier and the lighting wires
during a sharp thunder-storm. A startling manifestation of this kind
happened at Sunbury, when the vivid display drove nervous guests of the
hotel out into the street, and the providential storm led Mr. Luther Stieringer
to invent the "insulating joint." This separated the two lighting systems
thoroughly, went into immediate service, and is universally used to-day.
Returning to the more specific subject of pioneer plants of importance,
that at Brockton must be considered for a moment, chiefly for the reason
that the city was the first in the world to possess an Edison station
distributing current through an underground three-wire network of
conductors—the essentially modern contemporaneous practice, standard
twenty-five years later. It was proposed to employ pole-line construction
with overhead wires, and a party of Edison engineers drove about the town
in an open barouche with a blue-print of the circuits and streets spread out
on their knees, to determine how much tree-trimming would be necessary.
When they came to some heavily shaded spots, the fine trees were marked
"T" to indicate that the work in getting through them would be "tough."
Where the trees were sparse and the foliage was thin, the same cheerful
band of vandals marked the spots "E" to indicate that there it would be
"easy" to run the wires. In those days public opinion was not so alive as
now to the desirability of preserving shade-trees, and of enhancing the
beauty of a city instead of destroying it. Brockton had a good deal of pride
in its fine trees, and a strong sentiment was very soon aroused against the

in its fine trees, and a strong sentiment was very soon aroused against the
Page 294
mutilation proposed so thoughtlessly. The investors in the enterprise were
ready and anxious to meet the extra cost of putting the wires underground.
Edison's own wishes were altogether for the use of the methods he had so
carefully devised; and hence that bustling home of shoe manufacture was
spared this infliction of more overhead wires.
The station equipment at Brockton consisted at first of three dynamos,
one of which was so arranged as to supply both sides of the system during
light loads by a breakdown switch connection. This arrangement interfered
with correct meter registration, as the meters on one side of the system
registered backward during the hours in which the combination was
employed. Hence, after supplying an all-night customer whose lamps were
on one side of the circuits, the company might be found to owe him some
thing substantial in the morning. Soon after the station went into operation
this ingenious plan was changed, and the third dynamo was replaced by two
others. The Edison construction department took entire charge of the
installation of the plant, and the formal opening was attended on October 1,
1883, by Mr. Edison, who then remained a week in ceaseless study and
consultation over the conditions developed by this initial three-wire
underground plant. Some idea of the confidence inspired by the fame of
Edison at this period is shown by the fact that the first theatre ever lighted
from a central station by incandescent lamps was designed this year, and
opened in 1884 at Brockton with an equipment of three hundred lamps. The
theatre was never piped for gas! It was also from the Brockton central
station that current was first supplied to a fire-engine house—another
display of remarkably early belief in the trustworthiness of the service,
under conditions where continuity of lighting was vital. The building was
equipped in such a manner that the striking of the fire-alarm would light
every lamp in the house automatically and liberate the horses. It was at this
central station that Lieutenant Sprague began his historic work on the
electric motor; and here that another distinguished engineer and inventor,
Mr. H. Ward Leonard, installed the meters and became meter man, in order
that he might study in every intimate detail the improvements and
refinements necessary in that branch of the industry.
The authors are indebted for these facts and some other data embodied in
this book to Mr. W. J. Jenks, who as manager of this plant here made his
debut in the Edison ranks. He had been connected with local telephone
interests, but resigned to take active charge of this plant, imbibing quickly
ready and anxious to meet the extra cost of putting the wires underground.
Edison's own wishes were altogether for the use of the methods he had so
carefully devised; and hence that bustling home of shoe manufacture was
spared this infliction of more overhead wires.
The station equipment at Brockton consisted at first of three dynamos,
one of which was so arranged as to supply both sides of the system during
light loads by a breakdown switch connection. This arrangement interfered
with correct meter registration, as the meters on one side of the system
registered backward during the hours in which the combination was
employed. Hence, after supplying an all-night customer whose lamps were
on one side of the circuits, the company might be found to owe him some
thing substantial in the morning. Soon after the station went into operation
this ingenious plan was changed, and the third dynamo was replaced by two
others. The Edison construction department took entire charge of the
installation of the plant, and the formal opening was attended on October 1,
1883, by Mr. Edison, who then remained a week in ceaseless study and
consultation over the conditions developed by this initial three-wire
underground plant. Some idea of the confidence inspired by the fame of
Edison at this period is shown by the fact that the first theatre ever lighted
from a central station by incandescent lamps was designed this year, and
opened in 1884 at Brockton with an equipment of three hundred lamps. The
theatre was never piped for gas! It was also from the Brockton central
station that current was first supplied to a fire-engine house—another
display of remarkably early belief in the trustworthiness of the service,
under conditions where continuity of lighting was vital. The building was
equipped in such a manner that the striking of the fire-alarm would light
every lamp in the house automatically and liberate the horses. It was at this

debut in the Edison ranks. He had been connected with local telephone
interests, but resigned to take active charge of this plant, imbibing quickly
Page 295
the traditional Edison spirit, working hard all day and sleeping in the station
at night on a cot brought there for that purpose. It was a time of
uninterrupted watchfulness. The difficulty of obtaining engineers in those
days to run the high-speed engines (three hundred and fifty revolutions per
minute) is well illustrated by an amusing incident in the very early history
of the station. A locomotive engineer had been engaged, as it was supposed
he would not be afraid of anything. One evening there came a sudden flash
of fire and a spluttering, sizzling noise. There had been a short-circuit on
the copper mains in the station. The fireman hid behind the boiler and the
engineer jumped out of the window. Mr. Sprague realized the trouble,
quickly threw off the current and stopped the engine.
Mr. Jenks relates another humorous incident in connection with this
plant: "One night I heard a knock at the office door, and on opening it saw
two well-dressed ladies, who asked if they might be shown through. I
invited them in, taking them first to the boiler-room, where I showed them
the coal-pile, explaining that this was used to generate steam in the boiler.
We then went to the dynamo-room, where I pointed out the machines
converting the steam-power into electricity, appearing later in the form of
light in the lamps. After that they were shown the meters by which the
consumption of current was measured. They appeared to be interested, and I
proceeded to enter upon a comparison of coal made into gas or burned
under a boiler to be converted into electricity. The ladies thanked me
effusively and brought their visit to a close. As they were about to go
through the door, one of them turned to me and said: 'We have enjoyed this
visit very much, but there is one question we would like to ask: What is it
that you make here?'"
The Brockton station was for a long time a show plant of the Edison
company, and had many distinguished visitors, among them being Prof.
Elihu Thomson, who was present at the opening, and Sir W. H. Preece, of
London. The engineering methods pursued formed the basis of similar
installations in Lawrence, Massachusetts, in November, 1883; in Fall River,
Massachusetts, in December, 1883; and in Newburgh, New York, the
following spring.
Another important plant of this period deserves special mention, as it was
the pioneer in the lighting of large spaces by incandescent lamps. This
installation of five thousand lamps on the three-wire system was made to
at night on a cot brought there for that purpose. It was a time of
uninterrupted watchfulness. The difficulty of obtaining engineers in those

Another important plant of this period deserves special mention, as it was
the pioneer in the lighting of large spaces by incandescent lamps. This
installation of five thousand lamps on the three-wire system was made to
Page 296
illuminate the buildings at the Louisville, Kentucky, Exposition in 1883,
and, owing to the careful surveys, calculations, and preparations of H. M.
Byllesby and the late Luther Stieringer, was completed and in operation
within six weeks after the placing of the order. The Jury of Awards, in
presenting four medals to the Edison company, took occasion to pay a high
compliment to the efficiency of the system. It has been thought by many
that the magnificent success of this plant did more to stimulate the growth
of the incandescent lighting business than any other event in the history of
the Edison company. It was literally the beginning of the electrical
illumination of American Expositions, carried later to such splendid
displays as those of the Chicago World's Fair in 1893, Buffalo in 1901, and
St. Louis in 1904.
Thus the art was set going in the United States under many difficulties,
but with every sign of coming triumph. Reference has already been made to
the work abroad in Paris and London. The first permanent Edison station in
Europe was that at Milan, Italy, for which the order was given as early as
May, 1882, by an enterprising syndicate. Less than a year later, March 3,
1883, the installation was ready and was put in operation, the Theatre Santa
Radegonda having been pulled down and a new central-station building
erected in its place—probably the first edifice constructed in Europe for the
specific purpose of incandescent lighting. Here "Jumbos" were installed
from time to time, until at last there were no fewer than ten of them; and
current was furnished to customers with a total of nearly ten thousand
lamps connected to the mains. This pioneer system was operated
continuously until February 9, 1900, or for a period of about seventeen
years, when the sturdy old machines, still in excellent condition, were put
out of service, so that a larger plant could be installed to meet the demand.
This new plant takes high-tension polyphase current from a water-power
thirty or forty miles away at Paderno, on the river Adda, flowing from the
Apennines; but delivers low-tension direct current for distribution to the
regular Edison three-wire system throughout Milan.
About the same time that southern Europe was thus opened up to the new
system, South America came into line, and the first Edison central station
there was installed at Santiago, Chile, in the summer of 1883, under the
supervision of Mr. W. N. Stewart. This was the result of the success
obtained with small isolated plants, leading to the formation of an Edison
company. It can readily be conceived that at such an extreme distance from
and, owing to the careful surveys, calculations, and preparations of H. M.
Byllesby and the late Luther Stieringer, was completed and in operation

Page 297
the source of supply of apparatus the plant was subject to many peculiar
difficulties from the outset, of which Mr. Stewart speaks as follows: "I
made an exhibition of the 'Jumbo' in the theatre at Santiago, and on the first
evening, when it was filled with the aristocracy of the city, I discovered to
my horror that the binding wire around the armature was slowly stripping
off and going to pieces. We had no means of boring out the field magnets,
and we cut grooves in them. I think the machine is still running (1907). The
station went into operation soon after with an equipment of eight Edison 'K'
dynamos with certain conditions inimical to efficiency, but which have not
hindered the splendid expansion of the local system. With those eight
dynamos we had four belts between each engine and the dynamo. The
steam pressure was limited to seventy-five pounds per square inch. We had
two-wire underground feeders, sent without any plans or specifications for
their installation. The station had neither voltmeter nor ammeter. The
current pressure was regulated by a galvanometer. We were using coal
costing $12 a ton, and were paid for our light in currency worth fifty cents
on the dollar. The only thing I can be proud of in connection with the plant
is the fact that I did not design it, that once in a while we made out to pay
its operating expenses, and that occasionally we could run it for three
months without a total breakdown."
It was not until 1885 that the first Edison station in Germany was
established; but the art was still very young, and the plant represented
pioneer lighting practice in the Empire. The station at Berlin comprised five
boilers, and six vertical steam-engines driving by belts twelve Edison
dynamos, each of about fifty-five horse-power capacity. A model of this
station is preserved in the Deutschen Museum at Munich. In the bulletin of
the Berlin Electricity Works for May, 1908, it is said with regard to the
events that led up to the creation of the system, as noted already at the
Rathenau celebration: "The year 1881 was a mile-stone in the history of the
Allgemeine Elektricitaets Gesellschaft. The International Electrical
Exposition at Paris was intended to place before the eyes of the civilized
world the achievements of the century. Among the exhibits of that
Exposition was the Edison system of incandescent lighting. IT BECAME
THE BASIS OF MODERN HEAVY CURRENT TECHNICS." The last
phrase is italicized as being a happy and authoritative description, as well as
a tribute.

This chapter would not be complete if it failed to include some reference
to a few of the earlier isolated plants of a historic character. Note has
already been made of the first Edison plants afloat on the Jeannette and
Columbia, and the first commercial plant in the New York lithographic
establishment. The first mill plant was placed in the woollen factory of
James Harrison at Newburgh, New York, about September 15, 1881. A year
later, Mr. Harrison wrote with some pride: "I believe my mill was the first
lighted with your electric light, and therefore may be called No. 1. Besides
being job No. 1 it is a No. 1 job, and a No. 1 light, being better and cheaper
than gas and absolutely safe as to fire." The first steam-yacht lighted by
incandescent lamps was James Gordon Bennett's Namouna, equipped early
in 1882 with a plant for one hundred and twenty lamps of eight
candlepower, which remained in use there many years afterward.
The first Edison plant in a hotel was started in October, 1881, at the Blue
Mountain House in the Adirondacks, and consisted of two "Z" dynamos
with a complement of eight and sixteen candle lamps. The hotel is situated
at an elevation of thirty-five hundred feet above the sea, and was at that
time forty miles from the railroad. The machinery was taken up in pieces on
the backs of mules from the foot of the mountain. The boilers were fired by
wood, as the economical transportation of coal was a physical impossibility.
For a six-hour run of the plant one-quarter of a cord of wood was required,
at a cost of twenty-five cents per cord.
The first theatre in the United States to be lighted by an Edison isolated
plant was the Bijou Theatre, Boston. The installation of boilers, engines,
dynamos, wiring, switches, fixtures, three stage regulators, and six hundred
and fifty lamps, was completed in eleven days after receipt of the order, and
the plant was successfully operated at the opening of the theatre, on
December 12, 1882.
The first plant to be placed on a United States steamship was the one
consisting of an Edison "Z" dynamo and one hundred and twenty eight-
candle lamps installed on the Fish Commission's steamer Albatross in 1883.
The most interesting feature of this installation was the employment of
special deep-sea lamps, supplied with current through a cable nine hundred
and forty feet in length, for the purpose of alluring fish. By means of the
brilliancy of the lamps marine animals in the lower depths were attracted
and then easily ensnared.

CHAPTER XVIII
THE ELECTRIC RAILWAY
EDISON had no sooner designed his dynamo in 1879 than he adopted
the same form of machine for use as a motor. The two are shown in the
Scientific American of October 18, 1879, and are alike, except that the
dynamo is vertical and the motor lies in a horizontal position, the article
remarking: "Its construction differs but slightly from the electric generator."
This was but an evidence of his early appreciation of the importance of
electricity as a motive power; but it will probably surprise many people to
know that he was the inventor of an electric motor before he perfected his
incandescent lamp. His interest in the subject went back to his connection
with General Lefferts in the days of the evolution of the stock ticker. While
Edison was carrying on his shop at Newark, New Jersey, there was
considerable excitement in electrical circles over the Payne motor, in regard
to the alleged performance of which Governor Cornell of New York and
other wealthy capitalists were quite enthusiastic. Payne had a shop in
Newark, and in one small room was the motor, weighing perhaps six
hundred pounds. It was of circular form, incased in iron, with the ends of
several small magnets sticking through the floor. A pulley and belt,
connected to a circular saw larger than the motor, permitted large logs of
oak timber to be sawed with ease with the use of two small cells of battery.
Edison's friend, General Lefferts, had become excited and was determined
to invest a large sum of money in the motor company, but knowing Edison's
intimate familiarity with all electrical subjects he was wise enough to ask
his young expert to go and see the motor with him. At an appointed hour
Edison went to the office of the motor company and found there the
venerable Professor Morse, Governor Cornell, General Lefferts, and many
others who had been invited to witness a performance of the motor. They all
proceeded to the room where the motor was at work. Payne put a wire in
the binding-post of the battery, the motor started, and an assistant began
sawing a heavy oak log. It worked beautifully, and so great was the power
developed, apparently, from the small battery, that Morse exclaimed: "I am

Page 301
thankful that I have lived to see this day." But Edison kept a close watch on
the motor. The results were so foreign to his experience that he knew there
was a trick in it. He soon discovered it. While holding his hand on the frame
of the motor he noticed a tremble coincident with the exhaust of an engine
across the alleyway, and he then knew that the power came from the engine
by a belt under the floor, shifted on and off by a magnet, the other magnets
being a blind. He whispered to the General to put his hand on the frame of
the motor, watch the exhaust, and note the coincident tremor. The General
did so, and in about fifteen seconds he said: "Well, Edison, I must go now.
This thing is a fraud." And thus he saved his money, although others not so
shrewdly advised were easily persuaded to invest by such a demonstration.
A few years later, in 1878, Edison went to Wyoming with a group of
astronomers, to test his tasimeter during an eclipse of the sun, and saw the
land white to harvest. He noticed the long hauls to market or elevator that
the farmers had to make with their loads of grain at great expense, and
conceived the idea that as ordinary steam-railroad service was too costly,
light electric railways might be constructed that could be operated
automatically over simple tracks, the propelling motors being controlled at
various points. Cheap to build and cheap to maintain, such roads would be a
great boon to the newer farming regions of the West, where the highways
were still of the crudest character, and where transportation was the gravest
difficulty with which the settlers had to contend. The plan seems to have
haunted him, and he had no sooner worked out a generator and motor that
owing to their low internal resistance could be operated efficiently, than he
turned his hand to the practical trial of such a railroad, applicable to both
the haulage of freight and the transportation of passengers. Early in 1880,
when the tremendous rush of work involved in the invention of the
incandescent lamp intermitted a little, he began the construction of a stretch
of track close to the Menlo Park laboratory, and at the same time built an
electric locomotive to operate over it.
This is a fitting stage at which to review briefly what had been done in
electric traction up to that date. There was absolutely no art, but there had
been a number of sporadic and very interesting experiments made. The
honor of the first attempt of any kind appears to rest with this country and
with Thomas Davenport, a self-trained blacksmith, of Brandon, Vermont,
who made a small model of a circular electric railway and cars in 1834, and
exhibited it the following year in Springfield, Boston, and other cities. Of

course he depended upon batteries for current, but the fundamental idea was
embodied of using the track for the circuit, one rail being positive and the
other negative, and the motor being placed across or between them in
multiple arc to receive the current. Such are also practically the methods of
to-day. The little model was in good preservation up to the year 1900, when,
being shipped to the Paris Exposition, it was lost, the steamer that carried it
foundering in mid-ocean. The very broad patent taken out by this simple
mechanic, so far ahead of his times, was the first one issued in America for
an electric motor. Davenport was also the first man to apply electric power
to the printing-press, in 1840. In his traction work he had a close second in
Robert Davidson, of Aberdeen, Scotland, who in 1839 operated both a lathe
and a small locomotive with the motor he had invented. His was the credit
of first actually carrying passengers—two at a time, over a rough plank road
—while it is said that his was the first motor to be tried on real tracks, those
of the Edinburgh-Glasgow road, making a speed of four miles an hour.
The curse of this work and of all that succeeded it for a score of years
was the necessity of depending upon chemical batteries for current, the
machine usually being self-contained and hauling the batteries along with
itself, as in the case of the famous Page experiments in April, 1851, when a
speed of nineteen miles an hour was attained on the line of the Washington
& Baltimore road. To this unfruitful period belonged, however, the crude
idea of taking the current from a stationary source of power by means of an
overhead contact, which has found its practical evolution in the modern
ubiquitous trolley; although the patent for this, based on his caveat of 1879,
was granted several years later than that to Stephen D. Field, for the
combination of an electric motor operated by means of a current from a
stationary dynamo or source of electricity conducted through the rails. As a
matter of fact, in 1856 and again in 1875, George F. Green, a jobbing
machinist, of Kalamazoo, Michigan, built small cars and tracks to which
current was fed from a distant battery, enough energy being utilized to haul
one hundred pounds of freight or one passenger up and down a "road" two
hundred feet long. All the work prior to the development of the dynamo as a
source of current was sporadic and spasmodic, and cannot be said to have
left any trace on the art, though it offered many suggestions as to operative
methods.
The close of the same decade of the nineteenth century that saw the
electric light brought to perfection, saw also the realization in practice of all
embodied of using the track for the circuit, one rail being positive and the
other negative, and the motor being placed across or between them in
multiple arc to receive the current. Such are also practically the methods of
to-day. The little model was in good preservation up to the year 1900, when,
being shipped to the Paris Exposition, it was lost, the steamer that carried it
foundering in mid-ocean. The very broad patent taken out by this simple
mechanic, so far ahead of his times, was the first one issued in America for
an electric motor. Davenport was also the first man to apply electric power
to the printing-press, in 1840. In his traction work he had a close second in
Robert Davidson, of Aberdeen, Scotland, who in 1839 operated both a lathe
and a small locomotive with the motor he had invented. His was the credit
of first actually carrying passengers—two at a time, over a rough plank road
—while it is said that his was the first motor to be tried on real tracks, those
of the Edinburgh-Glasgow road, making a speed of four miles an hour.

The close of the same decade of the nineteenth century that saw the
electric light brought to perfection, saw also the realization in practice of all
Page 303
the hopes of fifty years as to electric traction. Both utilizations depended
upon the supply of current now cheaply obtainable from the dynamo. These
arts were indeed twins, feeding at inexhaustible breasts. In 1879, at the
Berlin Exhibition, the distinguished firm of Siemens, to whose ingenuity
and enterprise electrical development owes so much, installed a road about
one-third of a mile in length, over which the locomotive hauled a train of
three small cars at a speed of about eight miles an hour, carrying some
twenty persons every trip. Current was fed from a dynamo to the motor
through a central third rail, the two outer rails being joined together as the
negative or return circuit. Primitive but essentially successful, this little
road made a profound impression on the minds of many inventors and
engineers, and marked the real beginning of the great new era, which has
already seen electricity applied to the operation of main lines of trunk
railways. But it is not to be supposed that on the part of the public there was
any great amount of faith then discernible; and for some years the pioneers
had great difficulty, especially in this country, in raising money for their
early modest experiments. Of the general conditions at this moment Frank
J. Sprague says in an article in the Century Magazine of July, 1905, on the
creation of the new art: "Edison was perhaps nearer the verge of great
electric-railway possibilities than any other American. In the face of much
adverse criticism he had developed the essentials of the low-internal-
resistance dynamo with high-resistance field, and many of the essential
features of multiple-arc distribution, and in 1880 he built a small road at his
laboratory at Menlo Park."
On May 13th of the year named this interesting road went into operation
as the result of hard and hurried work of preparation during the spring
months. The first track was about a third of a mile in length, starting from
the shops, following a country road, passing around a hill at the rear and
curving home, in the general form of the letter "U." The rails were very
light. Charles T. Hughes, who went with Edison in 1879, and was in charge
of much of the work, states that they were "second" street-car rails,
insulated with tar canvas paper and things of that sort—"asphalt." They
were spiked down on ordinary sleepers laid upon the natural grade, and the
gauge was about three feet six inches. At one point the grade dropped some
sixty feet in a distance of three hundred, and the curves were of recklessly
short radius. The dynamos supplying current to the road were originally two
of the standard size "Z" machines then being made at the laboratory,
upon the supply of current now cheaply obtainable from the dynamo. These

of the standard size "Z" machines then being made at the laboratory,
Page 304
popularly known throughout the Edison ranks as "Longwaisted Mary
Anns," and the circuits from these were carried out to the rails by
underground conductors. They were not large—about twelve horse-power
each—generating seventy-five amperes of current at one hundred and ten
volts, so that not quite twenty-five horse-power of electrical energy was
available for propulsion.
The locomotive built while the roadbed was getting ready was a four-
wheeled iron truck, an ordinary flat dump-car about six feet long and four
feet wide, upon which was mounted a "Z" dynamo used as a motor, so that
it had a capacity of about twelve horsepower. This machine was laid on its
side, with the armature end coming out at the front of the locomotive, and
the motive power was applied to the driving-axle by a cumbersome series
of friction pulleys. Each wheel of the locomotive had a metal rim and a
centre web of wood or papier-mache, and the current picked up by one set
of wheels was carried through contact brushes and a brass hub to the motor;
the circuit back to the track, or other rail, being closed through the other
wheels in a similar manner. The motor had its field-magnet circuit in
permanent connection as a shunt across the rails, protected by a crude bare
copper-wire safety-catch. A switch in the armature circuit enabled the
motorman to reverse the direction of travel by reversing the current flow
through the armature coils.
Things went fairly well for a time on that memorable Thursday
afternoon, when all the laboratory force made high holiday and scrambled
for foothold on the locomotive for a trip; but the friction gearing was not
equal to the sudden strain put upon it during one run and went to pieces.
Some years later, also, Daft again tried friction gear in his historical
experiments on the Manhattan Elevated road, but the results were attended
with no greater success. The next resort of Edison was to belts, the armature
shafting belted to a countershaft on the locomotive frame, and the
countershaft belted to a pulley on the car-axle. The lever which threw the
former friction gear into adjustment was made to operate an idler pulley for
tightening the axle-belt. When the motor was started, the armature was
brought up to full revolution and then the belt was tightened on the car-axle,
compelling motion of the locomotive. But the belts were liable to slip a
great deal in the process, and the chafing of the belts charred them badly. If
that did not happen, and if the belt was made taut suddenly, the armature
burned out—which it did with disconcerting frequency. The next step was

Page 305
to use a number of resistance-boxes in series with the armature, so that the
locomotive could start with those in circuit, and then the motorman could
bring it up to speed gradually by cutting one box out after the other. To stop
the locomotive, the armature circuit was opened by the main switch,
stopping the flow of current, and then brakes were applied by long levers.
Matters generally and the motors in particular went much better, even if the
locomotive was so freely festooned with resistance-boxes all of perceptible
weight and occupying much of the limited space. These details show
forcibly and typically the painful steps of advance that every inventor in
this new field had to make in the effort to reach not alone commercial
practicability, but mechanical feasibility. It was all empirical enough; but
that was the only way open even to the highest talent.
Smugglers landing laces and silks have been known to wind them around
their bodies, as being less ostentatious than carrying them in a trunk. Edison
thought his resistance-boxes an equally superfluous display, and therefore
ingeniously wound some copper resistance wire around one of the legs of
the motor field magnet, where it was out of the way, served as a useful extra
field coil in starting up the motor, and dismissed most of the boxes back to
the laboratory—a few being retained under the seat for chance emergencies.
Like the boxes, this coil was in series with the armature, and subject to
plugging in and out at will by the motorman. Thus equipped, the locomotive
was found quite satisfactory, and long did yeoman service. It was given
three cars to pull, one an open awning-car with two park benches placed
back to back; one a flat freight-car, and one box-car dubbed the "Pullman,"
with which Edison illustrated a system of electric braking. Although work
had been begun so early in the year, and the road had been operating since
May, it was not until July that Edison executed any application for patents
on his "electromagnetic railway engine," or his ingenious braking system.
Every inventor knows how largely his fate lies in the hands of a competent
and alert patent attorney, in both the preparation and the prosecution of his
case; and Mr. Sprague is justified in observing in his Century article: "The
paucity of controlling claims obtained in these early patents is remarkable."
It is notorious that Edison did not then enjoy the skilful aid in safeguarding
his ideas that he commanded later.
The daily newspapers and technical journals lost no time in bringing the
road to public attention, and the New York Herald of June 25th was swift to
suggest that here was the locomotive that would be "most pleasing to the

suggest that here was the locomotive that would be "most pleasing to the
Page 306
average New Yorker, whose head has ached with noise, whose eyes have
been filled with dust, or whose clothes have been ruined with oil." A couple
of days later, the Daily Graphic illustrated and described the road and
published a sketch of a one-hundred-horse-power electric locomotive for
the use of the Pennsylvania Railroad between Perth Amboy and Rahway.
Visitors, of course, were numerous, including many curious, sceptical
railroad managers, few if any of whom except Villard could see the slightest
use for the new motive power. There is, perhaps, some excuse for such
indifference. No men in the world have more new inventions brought to
them than railroad managers, and this was the rankest kind of novelty. It
was not, indeed, until a year later, in May, 1881, that the first regular road
collecting fares was put in operation—a little stretch of one and a half miles
from Berlin to Lichterfelde, with one miniature motorcar. Edison was in
reality doing some heavy electric-railway engineering, his apparatus full of
ideas, suggestions, prophecies; but to the operators of long trunk lines it
must have seemed utterly insignificant and "excellent fooling."
Speaking of this situation, Mr. Edison says: "One day Frank Thomson,
the President of the Pennsylvania Railroad, came out to see the electric light
and the electric railway in operation. The latter was then about a mile long.
He rode on it. At that time I was getting out plans to make an electric
locomotive of three hundred horse-power with six-foot drivers, with the
idea of showing people that they could dispense with their steam
locomotives. Mr. Thomson made the objection that it was impracticable,
and that it would be impossible to supplant steam. His great experience and
standing threw a wet blanket on my hopes. But I thought he might perhaps
be mistaken, as there had been many such instances on record. I continued
to work on the plans, and about three years later I started to build the
locomotive at the works at Goerck Street, and had it about finished when I
was switched off on some other work. One of the reasons why I felt the
electric railway to be eminently practical was that Henry Villard, the
President of the Northern Pacific, said that one of the greatest things that
could be done would be to build right-angle feeders into the wheat-fields of
Dakota and bring in the wheat to the main lines, as the farmers then had to
draw it from forty to eighty miles. There was a point where it would not pay
to raise it at all; and large areas of the country were thus of no value. I
conceived the idea of building a very light railroad of narrow gauge, and
had got all the data as to the winds on the plains, and found that it would be
been filled with dust, or whose clothes have been ruined with oil." A couple

Page 307
possible with very large windmills to supply enough power to drive those
wheat trains."
Among others who visited the little road at this juncture were persons
interested in the Manhattan Elevated system of New York, on which
experiments were repeatedly tried later, but which was not destined to adopt
a method so obviously well suited to all the conditions until after many
successful demonstrations had been made on elevated roads elsewhere. It
must be admitted that Mr. Edison was not very profoundly impressed with
the desire entertained in that quarter to utilize any improvement, for he
remarks: "When the Elevated Railroad in New York, up Sixth Avenue, was
started there was a great clamor about the noise, and injunctions were
threatened. The management engaged me to make a report on the cause of
the noise. I constructed an instrument that would record the sound, and set
out to make a preliminary report, but I found that they never intended to do
anything but let the people complain."
It was upon the co-operation of Villard that Edison fell back, and an
agreement was entered into between them on September 14, 1881, which
provided that the latter would "build two and a half miles of electric railway
at Menlo Park, equipped with three cars, two locomotives, one for freight,
and one for passengers, capacity of latter sixty miles an hour. Capacity
freight engine, ten tons net freight; cost of handling a ton of freight per mile
per horse-power to be less than ordinary locomotive.... If experiments are
successful, Villard to pay actual outlay in experiments, and to treat with the
Light Company for the installation of at least fifty miles of electric railroad
in the wheat regions." Mr. Edison is authority for the statement that Mr.
Villard advanced between $35,000 and $40,000, and that the work done
was very satisfactory; but it did not end at that time in any practical results,
as the Northern Pacific went into the hands of a receiver, and Mr. Villard's
ability to help was hopelessly crippled. The directors of the Edison Electric
Light Company could not be induced to have anything to do with the
electric railway, and Mr. Insull states that the money advanced was treated
by Mr. Edison as a personal loan and repaid to Mr. Villard, for whom he had
a high admiration and a strong feeling of attachment. Mr. Insull says:
"Among the financial men whose close personal friendship Edison enjoyed,
I would mention Henry Villard, who, I think, had a higher appreciation of
the possibilities of the Edison system than probably any other man of his
time in Wall Street. He dropped out of the business at the time of the
wheat trains."

I would mention Henry Villard, who, I think, had a higher appreciation of
the possibilities of the Edison system than probably any other man of his
time in Wall Street. He dropped out of the business at the time of the
Page 308
consolidation of the Thomson-Houston Company with the Edison General
Electric Company; but from the earliest days of the business, when it was in
its experimental period, when the Edison light and power system was but an
idea, down to the day of his death, Henry Villard continued a strong
supporter not only with his influence, but with his money. He was the first
capitalist to back individually Edison's experiments in electric railways."
In speaking of his relationships with Mr. Villard at this time, Edison says:
"When Villard was all broken down, and in a stupor caused by his disasters
in connection with the Northern Pacific, Mrs. Villard sent for me to come
and cheer him up. It was very difficult to rouse him from his despair and
apathy, but I talked about the electric light to him, and its development, and
told him that it would help him win it all back and put him in his former
position. Villard made his great rally; he made money out of the electric
light; and he got back control of the Northern Pacific. Under no
circumstances can a hustler be kept down. If he is only square, he is bound
to get back on his feet. Villard has often been blamed and severely
criticised, but he was not the only one to blame. His engineers had spent
$20,000,000 too much in building the road, and it was not his fault if he
found himself short of money, and at that time unable to raise any more."
Villard maintained his intelligent interest in electric-railway
development, with regard to which Edison remarks: "At one time Mr.
Villard got the idea that he would run the mountain division of the Northern
Pacific Railroad by electricity. He asked me if it could be done. I said:
'Certainly, it is too easy for me to undertake; let some one else do it.' He
said: 'I want you to tackle the problem,' and he insisted on it. So I got up a
scheme of a third rail and shoe and erected it in my yard here in Orange.
When I got it all ready, he had all his division engineers come on to New
York, and they came over here. I showed them my plans, and the
unanimous decision of the engineers was that it was absolutely and utterly
impracticable. That system is on the New York Central now, and was also
used on the New Haven road in its first work with electricity."
At this point it may be well to cite some other statements of Edison as to
kindred work, with which he has not usually been associated in the public
mind. "In the same manner I had worked out for the Manhattan Elevated
Railroad a system of electric trains, and had the control of each car centred
at one place—multiple control. This was afterward worked out and made
Electric Company; but from the earliest days of the business, when it was in
its experimental period, when the Edison light and power system was but an
idea, down to the day of his death, Henry Villard continued a strong
supporter not only with his influence, but with his money. He was the first
capitalist to back individually Edison's experiments in electric railways."

Villard maintained his intelligent interest in electric-railway
development, with regard to which Edison remarks: "At one time Mr.
Villard got the idea that he would run the mountain division of the Northern
Pacific Railroad by electricity. He asked me if it could be done. I said:
'Certainly, it is too easy for me to undertake; let some one else do it.' He
said: 'I want you to tackle the problem,' and he insisted on it. So I got up a
scheme of a third rail and shoe and erected it in my yard here in Orange.
When I got it all ready, he had all his division engineers come on to New
York, and they came over here. I showed them my plans, and the
unanimous decision of the engineers was that it was absolutely and utterly
impracticable. That system is on the New York Central now, and was also
used on the New Haven road in its first work with electricity."
At this point it may be well to cite some other statements of Edison as to
kindred work, with which he has not usually been associated in the public
mind. "In the same manner I had worked out for the Manhattan Elevated
Railroad a system of electric trains, and had the control of each car centred
at one place—multiple control. This was afterward worked out and made
Page 309
practical by Frank Sprague. I got up a slot contact for street railways, and
have a patent on it—a sliding contact in a slot. Edward Lauterbach was
connected with the Third Avenue Railroad in New York—as counsel—and I
told him he was making a horrible mistake putting in the cable. I told him to
let the cable stand still and send electricity through it, and he would not
have to move hundreds of tons of metal all the time. He would rue the day
when he put the cable in." It cannot be denied that the prophecy was
fulfilled, for the cable was the beginning of the frightful financial collapse
of the system, and was torn out in a few years to make way for the
triumphant "trolley in the slot."
Incidental glimpses of this work are both amusing and interesting.
Hughes, who was working on the experimental road with Mr. Edison, tells
the following story: "Villard sent J. C. Henderson, one of his mechanical
engineers, to see the road when it was in operation, and we went down one
day—Edison, Henderson, and I—and went on the locomotive. Edison ran
it, and just after we started there was a trestle sixty feet long and seven feet
deep, and Edison put on all the power. When we went over it we must have
been going forty miles an hour, and I could see the perspiration come out on
Henderson. After we got over the trestle and started on down the track,
Henderson said: 'When we go back I will walk. If there is any more of that
kind of running I won't be in it myself.'" To the correspondence of
Grosvenor P. Lowrey we are indebted for a similar reminiscence, under date
of June 5, 1880: "Goddard and I have spent a part of the day at Menlo, and
all is glorious. I have ridden at forty miles an hour on Mr. Edison's electric
railway—and we ran off the track. I protested at the rate of speed over the
sharp curves, designed to show the power of the engine, but Edison said
they had done it often. Finally, when the last trip was to be taken, I said I
did not like it, but would go along. The train jumped the track on a short
curve, throwing Kruesi, who was driving the engine, with his face down in
the dirt, and another man in a comical somersault through some underbrush.
Edison was off in a minute, jumping and laughing, and declaring it a most
beautiful accident. Kruesi got up, his face bleeding and a good deal shaken;
and I shall never forget the expression of voice and face in which he said,
with some foreign accent: 'Oh! yes, pairfeckly safe.' Fortunately no other
hurts were suffered, and in a few minutes we had the train on the track and
running again."

All this rough-and-ready dealing with grades and curves was not mere
horse-play, but had a serious purpose underlying it, every trip having its
record as to some feature of defect or improvement. One particular set of
experiments relating to such work was made on behalf of visitors from
South America, and were doubtless the first tests of the kind made for that
continent, where now many fine electric street and interurban railway
systems are in operation. Mr. Edison himself supplies the following data:
"During the electric-railway experiments at Menlo Park, we had a short
spur of track up one of the steep gullies. The experiment came about in this
way. Bogota, the capital of Columbia, is reached on muleback—or was—
from Honda on the headwaters of the Magdalena River. There were parties
who wanted to know if transportation over the mule route could not be done
by electricity. They said the grades were excessive, and it would cost too
much to do it with steam locomotives, even if they could climb the grades. I
said: 'Well, it can't be much more than 45 per cent.; we will try that first. If
it will do that it will do anything else.' I started at 45 per cent. I got up an
electric locomotive with a grip on the rail by which it went up the 45 per
cent. grade. Then they said the curves were very short. I put the curves in.
We started the locomotive with nobody on it, and got up to twenty miles an
hour, taking those curves of very short radius; but it was weeks before we
could prevent it from running off. We had to bank the tracks up to an angle
of thirty degrees before we could turn the curve and stay on. These Spanish
parties were perfectly satisfied we could put in an electric railway from
Honda to Bogota successfully, and then they disappeared. I have never seen
them since. As usual, I paid for the experiment."
In the spring of 1883 the Electric Railway Company of America was
incorporated in the State of New York with a capital of $2,000,000 to
develop the patents and inventions of Edison and Stephen D. Field, to the
latter of whom the practical work of active development was confided, and
in June of the same year an exhibit was made at the Chicago Railway
Exposition, which attracted attention throughout the country, and did much
to stimulate the growing interest in electric-railway work. With the aid of
Messrs. F. B. Rae, C. L. Healy, and C. O. Mailloux a track and locomotive
were constructed for the company by Mr. Field and put in service in the
gallery of the main exhibition building. The track curved sharply at either
end on a radius of fifty-six feet, and the length was about one-third of a
mile. The locomotive named "The Judge," after Justice Field, an uncle of
horse-play, but had a serious purpose underlying it, every trip having its
record as to some feature of defect or improvement. One particular set of

Page 311
Stephen D. Field, took current from a central rail between the two outer
rails, that were the return circuit, the contact being a rubbing wire brush on
each side of the "third rail," answering the same purpose as the contact shoe
of later date. The locomotive weighed three tons, was twelve feet long, five
feet wide, and made a speed of nine miles an hour with a trailer car for
passengers. Starting on June 5th, when the exhibition closed on June 23d
this tiny but typical road had operated for over 118 hours, had made over
446 miles, and had carried 26,805 passengers. After the exposition closed
the outfit was taken during the same year to the exposition at Louisville,
Kentucky, where it was also successful, carrying a large number of
passengers. It deserves note that at Chicago regular railway tickets were
issued to paying passengers, the first ever employed on American electric
railways.
With this modest but brilliant demonstration, to which the illustrious
names of Edison and Field were attached, began the outburst of excitement
over electric railways, very much like the eras of speculation and
exploitation that attended only a few years earlier the introduction of the
telephone and the electric light, but with such significant results that the
capitalization of electric roads in America is now over $4,000,000,000, or
twice as much as that of the other two arts combined. There was a
tremendous rush into the electric-railway field after 1883, and an outburst
of inventive activity that has rarely, if ever, been equalled. It is remarkable
that, except Siemens, no European achieved fame in this early work, while
from America the ideas and appliances of Edison, Van Depoele, Sprague,
Field, Daft, and Short have been carried and adopted all over the world.
Mr. Edison was consulting electrician for the Electric Railway Company,
but neither a director nor an executive officer. Just what the trouble was as
to the internal management of the corporation it is hard to determine a
quarter of a century later; but it was equipped with all essential elements to
dominate an art in which after its first efforts it remained practically supine
and useless, while other interests forged ahead and reaped both the profit
and the glory. Dissensions arose between the representatives of the Field
and Edison interests, and in April, 1890, the Railway Company assigned its
rights to the Edison patents to the Edison General Electric Company,
recently formed by the consolidation of all the branches of the Edison light,
power, and manufacturing industry under one management. The only patent
rights remaining to the Railway Company were those under three Field
rails, that were the return circuit, the contact being a rubbing wire brush on
each side of the "third rail," answering the same purpose as the contact shoe
of later date. The locomotive weighed three tons, was twelve feet long, five

rights remaining to the Railway Company were those under three Field
Page 312
patents, one of which, with controlling claims, was put in suit June, 1890,
against the Jamaica & Brooklyn Road Company, a customer of the Edison
General Electric Company. This was, to say the least, a curious and
anomalous situation. Voluminous records were made by both parties to the
suit, and in the spring of 1894 the case was argued before the late Judge
Townsend, who wrote a long opinion dismissing the bill of complaint. [15]
The student will find therein a very complete and careful study of the early
electric-railway art. After this decision was rendered, the Electric Railway
Company remained for several years in a moribund condition, and on the
last day of 1896 its property was placed in the hands of a receiver. In
February of 1897 the receiver sold the three Field patents to their original
owner, and he in turn sold them to the Westinghouse Electric and
Manufacturing Company. The Railway Company then went into voluntary
dissolution, a sad example of failure to seize the opportunity at the
psychological moment, and on the part of the inventor to secure any
adequate return for years of effort and struggle in founding one of the great
arts. Neither of these men was squelched by such a calamitous result, but if
there were not something of bitterness in their feelings as they survey what
has come of their work, they would not be human.
As a matter of fact, Edison retained a very lively interest in electric-
railway progress long after the pregnant days at Menlo Park, one of the best
evidences of which is an article in the New York Electrical Engineer of
November 18, 1891, which describes some important and original
experiments in the direction of adapting electrical conditions to the larger
cities. The overhead trolley had by that time begun its victorious career, but
there was intense hostility displayed toward it in many places because of
the inevitable increase in the number of overhead wires, which, carrying, as
they did, a current of high voltage and large quantity, were regarded as a
menace to life and property. Edison has always manifested a strong
objection to overhead wires in cities, and urged placing them underground;
and the outcry against the overhead "deadly" trolley met with his instant
sympathy. His study of the problem brought him to the development of the
modern "substation," although the twists that later evolutions have given the
idea have left it scarcely recognizable.

Mr. Villard, as President of the Edison General Electric Company,
requested Mr. Edison, as electrician of the company, to devise a street-
railway system which should be applicable to the largest cities where the
use of the trolley would not be permitted, where the slot conduit system
would not be used, and where, in general, the details of construction should
be reduced to the simplest form. The limits imposed practically were such
as to require that the system should not cost more than a cable road to
install. Edison reverted to his ingenious lighting plan of years earlier, and
thus settled on a method by which current should be conveyed from the
power plant at high potential to motor-generators placed below the ground
in close proximity to the rails. These substations would convert the current
received at a pressure of, say, one thousand volts to one of twenty volts
available between rail and rail, with a corresponding increase in the volume
of the current. With the utilization of heavy currents at low voltage it
became necessary, of course, to devise apparatus which should be able to
pick up with absolute certainty one thousand amperes of current at this
pressure through two inches of mud, if necessary. With his wonted activity
and fertility Edison set about devising such a contact, and experimented
with metal wheels under all conditions of speed and track conditions. It was
several months before he could convey one hundred amperes by means of
such contacts, but he worked out at last a satisfactory device which was
equal to the task. The next point was to secure a joint between contiguous
rails such as would permit of the passage of several thousand amperes
without introducing undue resistance. This was also accomplished.
Objections were naturally made to rails out in the open on the street
surface carrying large currents at a potential of twenty volts. It was said that
vehicles with iron wheels passing over the tracks and spanning the two rails
would short-circuit the current, "chew" themselves up, and destroy the
dynamos generating the current by choking all that tremendous amount of
energy back into them. Edison tackled the objection squarely and short-
circuited his track with such a vehicle, but succeeded in getting only about
two hundred amperes through the wheels, the low voltage and the insulating
properties of the axle-grease being sufficient to account for such a result.
An iron bar was also used, polished, and with a man standing on it to insure
solid contact; but only one thousand amperes passed through it—i.e., the
amount required by a single car, and, of course, much less than the capacity
of the generators able to operate a system of several hundred cars.

Page 314
Further interesting experiments showed that the expected large leakage of
current from the rails in wet weather did not materialize. Edison found that
under the worst conditions with a wet and salted track, at a potential
difference of twenty volts between the two rails, the extreme loss was only
two and one-half horse-power. In this respect the phenomenon followed the
same rule as that to which telegraph wires are subject—namely, that the loss
of insulation is greater in damp, murky weather when the insulators are
covered with wet dust than during heavy rains when the insulators are
thoroughly washed by the action of the water. In like manner a heavy rain-
storm cleaned the tracks from the accumulations due chiefly to the
droppings of the horses, which otherwise served largely to increase the
conductivity. Of course, in dry weather the loss of current was practically
nothing, and, under ordinary conditions, Edison held, his system was in
respect to leakage and the problems of electrolytic attack of the current on
adjacent pipes, etc., as fully insulated as the standard trolley network of the
day. The cost of his system Mr. Edison placed at from $30,000 to $100,000
per mile of double track, in accordance with local conditions, and in this
respect comparing very favorably with the cable systems then so much in
favor for heavy traffic. All the arguments that could be urged in support of
this ingenious system are tenable and logical at the present moment; but the
trolley had its way except on a few lines where the conduit-and-shoe
method was adopted; and in the intervening years the volume of traffic
created and handled by electricity in centres of dense population has
brought into existence the modern subway.
But down to the moment of the preparation of this biography, Edison has
retained an active interest in transportation problems, and his latest work
has been that of reviving the use of the storage battery for street-car
purposes. At one time there were a number of storage-battery lines and cars
in operation in such cities as Washington, New York, Chicago, and Boston;
but the costs of operation and maintenance were found to be inordinately
high as compared with those of the direct-supply methods, and the battery
cars all disappeared. The need for them under many conditions remained,
as, for example, in places in Greater New York where the overhead trolley
wires are forbidden as objectionable, and where the ground is too wet or too
often submerged to permit of the conduit with the slot. Some of the roads in
Greater New York have been anxious to secure such cars, and, as usual, the
most resourceful electrical engineer and inventor of his times has made the

CHAPTER XIX
MAGNETIC ORE MILLING WORK
DURING the Hudson-Fulton celebration of October, 1909, Burgomaster
Van Leeuwen, of Amsterdam, member of the delegation sent officially from
Holland to escort the Half Moon and participate in the functions of the
anniversary, paid a visit to the Edison laboratory at Orange to see the
inventor, who may be regarded as pre-eminent among those of Dutch
descent in this country. Found, as usual, hard at work—this time on his

to remark that if he had achieved anything worth while, it was due to the
obstinacy and pertinacity he had inherited from his forefathers. To which it
may be added that not less equally have the nature of inheritance and the
quality of atavism been exhibited in his extraordinary predilection for the
miller's art. While those Batavian ancestors on the low shores of the Zuyder
Zee devoted their energies to grinding grain, he has been not less assiduous
than they in reducing the rocks of the earth itself to flour.
Although this phase of Mr. Edison's diverse activities is not as generally
known to the world as many others of a more popular character, the milling
of low-grade auriferous ores and the magnetic separation of iron ores have
been subjects of engrossing interest and study to him for many years.
Indeed, his comparatively unknown enterprise of separating magnetically
and putting into commercial form low-grade iron ore, as carried on at
Edison, New Jersey, proved to be the most colossal experiment that he has
ever made.
If a person qualified to judge were asked to answer categorically as to
whether or not that enterprise was a failure, he could truthfully answer both
yes and no. Yes, in that circumstances over which Mr. Edison had no
control compelled the shutting down of the plant at the very moment of
success; and no, in that the mechanically successful and commercially
practical results obtained, after the exercise of stupendous efforts and the
expenditure of a fortune, are so conclusive that they must inevitably be the

MAGNETIC ORE MILLING WORK
DURING the Hudson-Fulton celebration of October, 1909, Burgomaster
Van Leeuwen, of Amsterdam, member of the delegation sent officially from
Holland to escort the Half Moon and participate in the functions of the
anniversary, paid a visit to the Edison laboratory at Orange to see the
inventor, who may be regarded as pre-eminent among those of Dutch
descent in this country. Found, as usual, hard at work—this time on his
cement house, of which he showed the iron molds—Edison took occasion
to remark that if he had achieved anything worth while, it was due to the
obstinacy and pertinacity he had inherited from his forefathers. To which it
may be added that not less equally have the nature of inheritance and the

least a quarter of a century ahead of the times in the work now to be
considered.
Before proceeding to a specific description of this remarkable enterprise,
however, let us glance at an early experiment in separating magnetic iron
sands on the Atlantic sea-shore: "Some years ago I heard one day that down
at Quogue, Long Island, there were immense deposits of black magnetic
sand. This would be very valuable if the iron could be separated from the
sand. So I went down to Quogue with one of my assistants and saw there
for miles large beds of black sand on the beach in layers from one to six
inches thick—hundreds of thousands of tons. My first thought was that it
would be a very easy matter to concentrate this, and I found I could sell the
stuff at a good price. I put up a small plant, but just as I got it started a
tremendous storm came up, and every bit of that black sand went out to sea.
During the twenty-eight years that have intervened it has never come back."
This incident was really the prelude to the development set forth in this
chapter.
In the early eighties Edison became familiar with the fact that the Eastern
steel trade was suffering a disastrous change, and that business was slowly
drifting westward, chiefly by reason of the discovery and opening up of
enormous deposits of high-grade iron ore in the upper peninsula of
Michigan. This ore could be excavated very cheaply by means of improved
mining facilities, and transported at low cost to lake ports. Hence the iron
and steel mills east of the Alleghanies—compelled to rely on limited local
deposits of Bessemer ore, and upon foreign ores which were constantly
rising in value—began to sustain a serious competition with Western mills,
even in Eastern markets.
Long before this situation arose, it had been recognized by Eastern iron-
masters that sooner or later the deposits of high-grade ore would be
exhausted, and, in consequence, there would ensue a compelling necessity
to fall back on the low-grade magnetic ores. For many years it had been a
much-discussed question how to make these ores available for
transportation to distant furnaces. To pay railroad charges on ores carrying
perhaps 80 to 90 per cent. of useless material would be prohibitive. Hence
the elimination of the worthless "gangue" by concentration of the iron
particles associated with it, seemed to be the only solution of the problem.

Many attempts had been made in by-gone days to concentrate the iron in
such ores by water processes, but with only a partial degree of success. The
impossibility of obtaining a uniform concentrate was a most serious
objection, had there not indeed been other difficulties which rendered this
method commercially impracticable. It is quite natural, therefore, that the
idea of magnetic separation should have occurred to many inventors. Thus
we find numerous instances throughout the last century of experiments
along this line; and particularly in the last forty or fifty years, during which
various attempts have been made by others than Edison to perfect magnetic
separation and bring it up to something like commercial practice. At the
time he took up the matter, however, no one seems to have realized the full
meaning of the tremendous problems involved.
From 1880 to 1885, while still very busy in the development of his
electric-light system, Edison found opportunity to plan crushing and
separating machinery. His first patent on the subject was applied for and
issued early in 1880. He decided, after mature deliberation, that the
magnetic separation of low-grade ores on a colossal scale at a low cost was
the only practical way of supplying the furnace-man with a high quality of
iron ore. It was his opinion that it was cheaper to quarry and concentrate
lean ore in a big way than to attempt to mine, under adverse circumstances,
limited bodies of high-grade ore. He appreciated fully the serious nature of
the gigantic questions involved; and his plans were laid with a view to
exercising the utmost economy in the design and operation of the plant in
which he contemplated the automatic handling of many thousands of tons
of material daily. It may be stated as broadly true that Edison engineered to
handle immense masses of stuff automatically, while his predecessors
aimed chiefly at close separation.
Reduced to its barest, crudest terms, the proposition of magnetic
separation is simplicity itself. A piece of the ore (magnetite) may be reduced
to powder and the ore particles separated therefrom by the help of a simple
hand magnet. To elucidate the basic principle of Edison's method, let the
crushed ore fall in a thin stream past such a magnet. The magnetic particles
are attracted out of the straight line of the falling stream, and being heavy,
gravitate inwardly and fall to one side of a partition placed below. The non-
magnetic gangue descends in a straight line to the other side of the partition.

Simple though the principle appears, it was in its application to vast
masses of material and in the solving of great engineering problems
connected therewith that Edison's originality made itself manifest in the
concentrating works that he established in New Jersey, early in the nineties.
Not only did he develop thoroughly the refining of the crushed ore, so that
after it had passed the four hundred and eighty magnets in the mill, the
concentrates came out finally containing 91 to 93 per cent. of iron oxide,
but he also devised collateral machinery, methods and processes all
fundamental in their nature. These are too numerous to specify in detail, as
they extended throughout the various ramifications of the plant, but the
principal ones are worthy of mention, such as:
The giant rolls (for crushing).
Intermediate rolls.
Three-high rolls.
Giant cranes (215 feet long span).
Vertical dryer.
Belt conveyors.
Air separation.
Mechanical separation of phosphorus.
Briquetting.
That Mr. Edison's work was appreciated at the time is made evident by
the following extract from an article describing the Edison plant, published
in The Iron Age of October 28, 1897; in which, after mentioning his
struggle with adverse conditions, it says: "There is very little that is showy,
from the popular point of view, in the gigantic work which Mr. Edison has
done during these years, but to those who are capable of grasping the
difficulties encountered, Mr. Edison appears in the new light of a brilliant
constructing engineer grappling with technical and commercial problems of
the highest order. His genius as an inventor is revealed in many details of
the great concentrating plant.... But to our mind, originality of the highest
type as a constructor and designer appears in the bold way in which he
sweeps aside accepted practice in this particular field and attains results not
hitherto approached. He pursues methods in ore-dressing at which those
who are trained in the usual practice may well stand aghast. But considering
the special features of the problems to be solved, his methods will be
accepted as those economically wise and expedient."
A cursory glance at these problems will reveal their import. Mountains
must be reduced to dust; all this dust must be handled in detail, so to speak,
and from it must be separated the fine particles of iron constituting only
masses of material and in the solving of great engineering problems
connected therewith that Edison's originality made itself manifest in the

A cursory glance at these problems will reveal their import. Mountains
must be reduced to dust; all this dust must be handled in detail, so to speak,
and from it must be separated the fine particles of iron constituting only
Page 320
one-fourth or one-fifth of its mass; and then this iron-ore dust must be put
into such shape that it could be commercially shipped and used. One of the
most interesting and striking investigations made by Edison in this
connection is worthy of note, and may be related in his own words: "I felt
certain that there must be large bodies of magnetite in the East, which if
crushed and concentrated would satisfy the wants of the Eastern furnaces
for steel-making. Having determined to investigate the mountain regions of
New Jersey, I constructed a very sensitive magnetic needle, which would
dip toward the earth if brought over any considerable body of magnetic iron
ore. One of my laboratory assistants went out with me and we visited many
of the mines of New Jersey, but did not find deposits of any magnitude. One
day, however, as we drove over a mountain range, not known as iron-
bearing land, I was astonished to find that the needle was strongly attracted
and remained so; thus indicating that the whole mountain was underlaid
with vast bodies of magnetic ore.
"I knew it was a commercial problem to produce high-grade Bessemer
ore from these deposits, and took steps to acquire a large amount of the
property. I also planned a great magnetic survey of the East, and I believe it
remains the most comprehensive of its kind yet performed. I had a number
of men survey a strip reaching from Lower Canada to North Carolina. The
only instrument we used was the special magnetic needle. We started in
Lower Canada and travelled across the line of march twenty-five miles;
then advanced south one thousand feet; then back across the line of march
again twenty-five miles; then south another thousand feet, across again, and
so on. Thus we advanced all the way to North Carolina, varying our cross-
country march from two to twenty-five miles, according to geological
formation. Our magnetic needle indicated the presence and richness of the
invisible deposits of magnetic ore. We kept minute records of these
indications, and when the survey was finished we had exact information of
the deposits in every part of each State we had passed through. We also
knew the width, length, and approximate depth of every one of these
deposits, which were enormous.
"The amount of ore disclosed by this survey was simply fabulous. How
much so may be judged from the fact that in the three thousand acres
immediately surrounding the mills that I afterward established at Edison
there were over 200,000,000 tons of low-grade ore. I also secured sixteen
thousand acres in which the deposit was proportionately as large. These few

Page 321
acres alone contained sufficient ore to supply the whole United States iron
trade, including exports, for seventy years."
Given a mountain of rock containing only one-fifth to one-fourth
magnetic iron, the broad problem confronting Edison resolved itself into
three distinct parts—first, to tear down the mountain bodily and grind it to
powder; second, to extract from this powder the particles of iron mingled in
its mass; and, third, to accomplish these results at a cost sufficiently low to
give the product a commercial value.
Edison realized from the start that the true solution of this problem lay in
the continuous treatment of the material, with the maximum employment of
natural forces and the minimum of manual labor and generated power.
Hence, all his conceptions followed this general principle so faithfully and
completely that we find in the plant embodying his ideas the forces of
momentum and gravity steadily in harness and keeping the traces taut;
while there was no touch of the human hand upon the material from the
beginning of the treatment to its finish—the staff being employed mainly to
keep watch on the correct working of the various processes.
It is hardly necessary to devote space to the beginnings of the enterprise,
although they are full of interest. They served, however, to convince Edison
that if he ever expected to carry out his scheme on the extensive scale
planned, he could not depend upon the market to supply suitable machinery
for important operations, but would be obliged to devise and build it
himself. Thus, outside the steam-shovel and such staple items as engines,
boilers, dynamos, and motors, all of the diverse and complex machinery of
the entire concentrating plant, as subsequently completed, was devised by
him especially for the purpose. The necessity for this was due to the many
radical variations made from accepted methods.
No such departure was as radical as that of the method of crushing the
ore. Existing machinery for this purpose had been designed on the basis of
mining methods then in vogue, by which the rock was thoroughly shattered
by means of high explosives and reduced to pieces of one hundred pounds
or less. These pieces were then crushed by power directly applied. If a
concentrating mill, planned to treat five or six thousand tons per day, were
to be operated on this basis the investment in crushers and the supply of
power would be enormous, to say nothing of the risk of frequent
breakdowns by reason of multiplicity of machinery and parts. From a

Page 322
consideration of these facts, and with his usual tendency to upset traditional
observances, Edison conceived the bold idea of constructing gigantic rolls
which, by the force of momentum, would be capable of crushing individual
rocks of vastly greater size than ever before attempted. He reasoned that the
advantages thus obtained would be fourfold: a minimum of machinery and
parts; greater compactness; a saving of power; and greater economy in
mining. As this last-named operation precedes the crushing, let us first
consider it as it was projected and carried on by him.
Perhaps quarrying would be a better term than mining in this case, as
Edison's plan was to approach the rock and tear it down bodily. The faith
that "moves mountains" had a new opportunity. In work of this nature it had
been customary, as above stated, to depend upon a high explosive, such as
dynamite, to shatter and break the ore to lumps of one hundred pounds or
less. This, however, he deemed to be a most uneconomical process, for
energy stored as heat units in dynamite at $260 per ton was much more
expensive than that of calories in a ton of coal at $3 per ton. Hence, he
believed that only the minimum of work should be done with the costly
explosive; and, therefore, planned to use dynamite merely to dislodge great
masses of rock, and depended upon the steam-shovel, operated by coal
under the boiler, to displace, handle, and remove the rock in detail. This was
the plan that was subsequently put into practice in the great works at
Edison, New Jersey. A series of three-inch holes twenty feet deep were
drilled eight feet apart, about twelve feet back of the ore-bank, and into
these were inserted dynamite cartridges. The blast would dislodge thirty to
thirty-five thousand tons of rock, which was scooped up by great steam-
shovels and loaded on to skips carried by a line of cars on a narrow-gauge
railroad running to and from the crushing mill. Here the material was
automatically delivered to the giant rolls. The problem included handling
and crushing the "run of the mine," without selection. The steam-shovel did
not discriminate, but picked up handily single pieces weighing five or six
tons and loaded them on the skips with quantities of smaller lumps. When
the skips arrived at the giant rolls, their contents were dumped
automatically into a superimposed hopper. The rolls were well named, for
with ear-splitting noise they broke up in a few seconds the great pieces of
rock tossed in from the skips.

It is not easy to appreciate to the full the daring exemplified in these great
crushing rolls, or rather "rock-crackers," without having watched them in
Page 323
operation delivering their "solar-plexus" blows. It was only as one might
stand in their vicinity and hear the thunderous roar accompanying the
smashing and rending of the massive rocks as they disappeared from view
that the mind was overwhelmed with a sense of the magnificent proportions
of this operation. The enormous force exerted during this process may be
illustrated from the fact that during its development, in running one of the
early forms of rolls, pieces of rock weighing more than half a ton would be
shot up in the air to a height of twenty or twenty-five feet.
The giant rolls were two solid cylinders, six feet in diameter and five feet
long, made of cast iron. To the faces of these rolls were bolted a series of
heavy, chilled-iron plates containing a number of projecting knobs two
inches high. Each roll had also two rows of four-inch knobs, intended to
strike a series of hammer-like blows. The rolls were set face to face
fourteen inches apart, in a heavy frame, and the total weight was one
hundred and thirty tons, of which seventy tons were in moving parts. The
space between these two rolls allowed pieces of rock measuring less than
fourteen inches to descend to other smaller rolls placed below. The giant
rolls were belt-driven, in opposite directions, through friction clutches,
although the belt was not depended upon for the actual crushing. Previous
to the dumping of a skip, the rolls were speeded up to a circumferential
velocity of nearly a mile a minute, thus imparting to them the terrific
momentum that would break up easily in a few seconds boulders weighing
five or six tons each. It was as though a rock of this size had got in the way
of two express trains travelling in opposite directions at nearly sixty miles
an hour. In other words, it was the kinetic energy of the rolls that crumbled
up the rocks with pile-driver effect. This sudden strain might have tended to
stop the engine driving the rolls; but by an ingenious clutch arrangement the
belt was released at the moment of resistance in the rolls by reason of the
rocks falling between them. The act of breaking and crushing would
naturally decrease the tremendous momentum, but after the rock was
reduced and the pieces had passed through, the belt would again come into
play, and once more speed up the rolls for a repetition of their regular prize-
fighter duty.
On leaving the giant rolls the rocks, having been reduced to pieces not
larger than fourteen inches, passed into the series of "Intermediate Rolls" of
similar construction and operation, by which they were still further reduced,
and again passed on to three other sets of rolls of smaller dimensions. These
stand in their vicinity and hear the thunderous roar accompanying the
smashing and rending of the massive rocks as they disappeared from view
that the mind was overwhelmed with a sense of the magnificent proportions
of this operation. The enormous force exerted during this process may be
illustrated from the fact that during its development, in running one of the
early forms of rolls, pieces of rock weighing more than half a ton would be
shot up in the air to a height of twenty or twenty-five feet.
The giant rolls were two solid cylinders, six feet in diameter and five feet
long, made of cast iron. To the faces of these rolls were bolted a series of
heavy, chilled-iron plates containing a number of projecting knobs two
inches high. Each roll had also two rows of four-inch knobs, intended to
strike a series of hammer-like blows. The rolls were set face to face
fourteen inches apart, in a heavy frame, and the total weight was one
hundred and thirty tons, of which seventy tons were in moving parts. The
space between these two rolls allowed pieces of rock measuring less than
fourteen inches to descend to other smaller rolls placed below. The giant
rolls were belt-driven, in opposite directions, through friction clutches,
although the belt was not depended upon for the actual crushing. Previous
to the dumping of a skip, the rolls were speeded up to a circumferential
velocity of nearly a mile a minute, thus imparting to them the terrific
momentum that would break up easily in a few seconds boulders weighing
five or six tons each. It was as though a rock of this size had got in the way
of two express trains travelling in opposite directions at nearly sixty miles
an hour. In other words, it was the kinetic energy of the rolls that crumbled
up the rocks with pile-driver effect. This sudden strain might have tended to
stop the engine driving the rolls; but by an ingenious clutch arrangement the
belt was released at the moment of resistance in the rolls by reason of the
rocks falling between them. The act of breaking and crushing would
naturally decrease the tremendous momentum, but after the rock was
reduced and the pieces had passed through, the belt would again come into
play, and once more speed up the rolls for a repetition of their regular prize-
fighter duty.
On leaving the giant rolls the rocks, having been reduced to pieces not
larger than fourteen inches, passed into the series of "Intermediate Rolls" of
similar construction and operation, by which they were still further reduced,
and again passed on to three other sets of rolls of smaller dimensions. These
Page 324
latter rolls were also face-lined with chilled-iron plates; but, unlike the
larger ones, were positively driven, reducing the rock to pieces of about
one-half-inch size, or smaller. The whole crushing operation of reduction
from massive boulders to small pebbly pieces having been done in less time
than the telling has occupied, the product was conveyed to the "Dryer," a
tower nine feet square and fifty feet high, heated from below by great open
furnace fires. All down the inside walls of this tower were placed cast-iron
plates, nine feet long and seven inches wide, arranged alternately in "fish-
ladder" fashion. The crushed rock, being delivered at the top, would fall
down from plate to plate, constantly exposing different surfaces to the heat,
until it landed completely dried in the lower portion of the tower, where it
fell into conveyors which took it up to the stock-house.
This method of drying was original with Edison. At the time this adjunct
to the plant was required, the best dryer on the market was of a rotary type,
which had a capacity of only twenty tons per hour, with the expenditure of
considerable power. As Edison had determined upon treating two hundred
and fifty tons or more per hour, he decided to devise an entirely new type of
great capacity, requiring a minimum of power (for elevating the material),
and depending upon the force of gravity for handling it during the drying
process. A long series of experiments resulted in the invention of the tower
dryer with a capacity of three hundred tons per hour.
The rock, broken up into pieces about the size of marbles, having been
dried and conveyed to the stock-house, the surplusage was automatically
carried out from the other end of the stock-house by conveyors, to pass
through the next process, by which it was reduced to a powder. The
machinery for accomplishing this result represents another interesting and
radical departure of Edison from accepted usage. He had investigated all the
crushing-machines on the market, and tried all he could get. He found them
all greatly lacking in economy of operation; indeed, the highest results
obtainable from the best were 18 per cent. of actual work, involving a loss
of 82 per cent. by friction. His nature revolted at such an immense loss of
power, especially as he proposed the crushing of vast quantities of ore.
Thus, he was obliged to begin again at the foundation, and he devised a
crushing-machine which was subsequently named the "Three-High Rolls,"
and which practically reversed the above figures, as it developed 84 per
cent. of work done with only 16 per cent. loss in friction.

A brief description of this remarkable machine will probably interest the
reader. In the two end pieces of a heavy iron frame were set three rolls, or
cylinders—one in the centre, another below, and the other above—all three
being in a vertical line. These rolls were of cast iron three feet in diameter,
having chilled-iron smooth face-plates of considerable thickness. The
lowest roll was set in a fixed bearing at the bottom of the frame, and,
therefore, could only turn around on its axis. The middle and top rolls were
free to move up or down from and toward the lower roll, and the shafts of
the middle and upper rolls were set in a loose bearing which could slip up
and down in the iron frame. It will be apparent, therefore, that any material
which passed in between the top and the middle rolls, and the middle and
bottom rolls, could be ground as fine as might be desired, depending
entirely upon the amount of pressure applied to the loose rolls. In operation
the material passed first through the upper and middle rolls, and then
between the middle and lowest rolls.
This pressure was applied in a most ingenious manner. On the ends of the
shafts of the bottom and top rolls there were cylindrical sleeves, or
bearings, having seven sheaves, in which was run a half-inch endless wire
rope. This rope was wound seven times over the sheaves as above, and led
upward and over a single-groove sheave which was operated by the piston
of an air cylinder, and in this manner the pressure was applied to the rolls. It
will be seen, therefore, that the system consisted in a single rope passed
over sheaves and so arranged that it could be varied in length, thus
providing for elasticity in exerting pressure and regulating it as desired. The
efficiency of this system was incomparably greater than that of any other
known crusher or grinder, for while a pressure of one hundred and twenty-
five thousand pounds could be exerted by these rolls, friction was almost
entirely eliminated because the upper and lower roll bearings turned with
the rolls and revolved in the wire rope, which constituted the bearing
proper.
The same cautious foresight exercised by Edison in providing a safety
device—the fuse—to prevent fires in his electric-light system, was again
displayed in this concentrating plant, where, to save possible injury to its
expensive operating parts, he devised an analogous factor, providing all the
crushing machinery with closely calculated "safety pins," which, on being
overloaded, would shear off and thus stop the machine at once.

The rocks having thus been reduced to fine powder, the mass was ready
for screening on its way to the magnetic separators. Here again Edison
reversed prior practice by discarding rotary screens and devising a form of
tower screen, which, besides having a very large working capacity by
gravity, eliminated all power except that required to elevate the material.
The screening process allowed the finest part of the crushed rock to pass on,
by conveyor belts, to the magnetic separators, while the coarser particles
were in like manner automatically returned to the rolls for further reduction.
In a narrative not intended to be strictly technical, it would probably tire
the reader to follow this material in detail through the numerous steps
attending the magnetic separation. These may be seen in a diagram
reproduced from the above-named article in the Iron Age, and
supplemented by the following extract from the Electrical Engineer, New
York, October 28, 1897: "At the start the weakest magnet at the top frees
the purest particles, and the second takes care of others; but the third
catches those to which rock adheres, and will extract particles of which only
one-eighth is iron. This batch of material goes back for another crushing, so
that everything is subjected to an equality of refining. We are now in sight
of the real 'concentrates,' which are conveyed to dryer No. 2 for drying
again, and are then delivered to the fifty-mesh screens. Whatever is fine
enough goes through to the eight-inch magnets, and the remainder goes
back for recrushing. Below the eight-inch magnets the dust is blown out of
the particles mechanically, and they then go to the four-inch magnets for
final cleansing and separation.... Obviously, at each step the percentage of
felspar and phosphorus is less and less until in the final concentrates the
percentage of iron oxide is 91 to 93 per cent. As intimated at the outset, the
tailings will be 75 per cent. of the rock taken from the veins of ore, so that
every four tons of crude, raw, low-grade ore will have yielded roughly one
ton of high-grade concentrate and three tons of sand, the latter also having
its value in various ways."
This sand was transported automatically by belt conveyors to the rear of
the works to be stored and sold. Being sharp, crystalline, and even in
quality, it was a valuable by-product, finding a ready sale for building
purposes, railway sand-boxes, and various industrial uses. The concentrate,
in fine powdery form, was delivered in similar manner to a stock-house.

As to the next step in the process, we may now quote again from the
article in the Iron Age: "While Mr. Edison and his associates were working
on the problem of cheap concentration of iron ore, an added difficulty faced
them in the preparation of the concentrates for the market. Furnacemen
object to more than a very small proportion of fine ore in their mixtures,
particularly when the ore is magnetic, not easily reduced. The problem to be
solved was to market an agglomerated material so as to avoid the
drawbacks of fine ore. The agglomerated product must be porous so as to
afford access of the furnace-reducing gases to the ore. It must be hard
enough to bear transportation, and to carry the furnace burden without
crumbling to pieces. It must be waterproof, to a certain extent, because
considerations connected with securing low rates of freight make it
necessary to be able to ship the concentrates to market in open coal cars,
exposed to snow and rain. In many respects the attainment of these
somewhat conflicting ends was the most perplexing of the problems which
confronted Mr. Edison. The agglomeration of the concentrates having been
decided upon, two other considerations, not mentioned above, were of
primary importance—first, to find a suitable cheap binding material; and,
second, its nature must be such that very little would be necessary per ton of
concentrates. These severe requirements were staggering, but Mr. Edison's
courage did not falter. Although it seemed a well-nigh hopeless task, he
entered upon the investigation with his usual optimism and vim. After many
months of unremitting toil and research, and the trial of thousands of
experiments, the goal was reached in the completion of a successful
formula for agglomerating the fine ore and pressing it into briquettes by
special machinery."
This was the final process requisite for the making of a completed
commercial product. Its practice, of course, necessitated the addition of an
entirely new department of the works, which was carried into effect by the
construction and installation of the novel mixing and briquetting machinery,
together with extensions of the conveyors, with which the plant had already
been liberally provided.
Briefly described, the process consisted in mixing the concentrates with
the special binding material in machines of an entirely new type, and in
passing the resultant pasty mass into the briquetting machines, where it was
pressed into cylindrical cakes three inches in diameter and one and a half
inches thick, under successive pressures of 7800, 14,000, and 60,000

pounds. Each machine made these briquettes at the rate of sixty per minute,
and dropped them into bucket conveyors by which they were carried into
drying furnaces, through which they made five loops, and were then
delivered to cross-conveyors which carried them into the stock-house. At
the end of this process the briquettes were so hard that they would not break
or crumble in loading on the cars or in transportation by rail, while they
were so porous as to be capable of absorbing 26 per cent. of their own
volume in alcohol, but repelling water absolutely—perfect "old soaks."
Thus, with never-failing persistence and patience, coupled with intense
thought and hard work, Edison met and conquered, one by one, the complex
difficulties that confronted him. He succeeded in what he had set out to do,
and it is now to be noted that the product he had striven so sedulously to
obtain was a highly commercial one, for not only did the briquettes of
concentrated ore fulfil the purpose of their creation, but in use actually
tended to increase the working capacity of the furnace, as the following test,
quoted from the Iron Age, October 28, 1897, will attest: "The only trial of
any magnitude of the briquettes in the blast-furnace was carried through
early this year at the Crane Iron Works, Catasauqua, Pennsylvania, by
Leonard Peckitt.
"The furnace at which the test was made produces from one hundred to
one hundred and ten tons per day when running on the ordinary mixture.
The charging of briquettes was begun with a percentage of 25 per cent., and
was carried up to 100 per cent. The following is the record of the results:

"These figures prove that the yield of the furnace is considerably
increased. The Crane trial was too short to settle the question to what extent
the increase in product may be carried. This increase in output, of course,
means a reduction in the cost of labor and of general expenses.

consumption. In the case of the Crane trial there was a reduction from 30
per cent. to 12 per cent. of the ore charge.
"Finally, the fuel consumption is reduced, which in the case of the
Eastern plants, with their relatively costly coke, is a very important
consideration. It is regarded as possible that Eastern furnaces will be able to
use a smaller proportion of the costlier coke and correspondingly increase
in anthracite coal, which is a cheaper fuel in that section. So far as foundry
iron is concerned, the experience at Catasauqua, Pennsylvania, brief as it
has been, shows that a stronger and tougher metal is made."
Edison himself tells an interesting little story in this connection, when he
enjoyed the active help of that noble character, John Fritz, the distinguished
inventor and pioneer of the modern steel industry in America. He says:
"When I was struggling along with the iron-ore concentration, I went to see
several blast-furnace men to sell the ore at the market price. They saw I was
very anxious to sell it, and they would take advantage of my necessity. But I
happened to go to Mr. John Fritz, of the Bethlehem Steel Company, and
told him what I was doing. 'Well,' he said to me, 'Edison, you are doing a
good thing for the Eastern furnaces. They ought to help you, for it will help
us out. I am willing to help you. I mix a little sentiment with business, and I
will give you an order for one hundred thousand tons.' And he sat right
down and gave me the order."
The Edison concentrating plant has been sketched in the briefest outline
with a view of affording merely a bare idea of the great work of its
projector. To tell the whole story in detail and show its logical sequence,
step by step, would take little less than a volume in itself, for Edison's
methods, always iconoclastic when progress is in sight, were particularly so
at the period in question. It has been said that "Edison's scrap-heap contains
the elements of a liberal education," and this was essentially true of the
"discard" during the ore-milling experience. Interesting as it might be to
follow at length the numerous phases of ingenious and resourceful
development that took place during those busy years, the limit of present

space forbids their relation. It would, however, be denying the justice that is
Edison's due to omit all mention of two hitherto unnamed items in
particular that have added to the world's store of useful devices. We refer
first to the great travelling hoisting-crane having a span of two hundred and
fifteen feet, and used for hoisting loads equal to ten tons, this being the
largest of the kind made up to that time, and afterward used as a model by
many others. The second item was the ingenious and varied forms of
conveyor belt, devised and used by Edison at the concentrating works, and
subsequently developed into a separate and extensive business by an
engineer to whom he gave permission to use his plans and patterns.
Edison's native shrewdness and knowledge of human nature was put to
practical use in the busy days of plant construction. It was found impossible
to keep mechanics on account of indifferent residential accommodations
afforded by the tiny village, remote from civilization, among the central
mountains of New Jersey. This puzzling question was much discussed
between him and his associate, Mr. W. S. Mallory, until finally he said to
the latter: "If we want to keep the men here we must make it attractive for
the women—so let us build some houses that will have running water and
electric lights, and rent at a low rate." He set to work, and in a day finished
a design for a type of house. Fifty were quickly built and fully described in
advertising for mechanics. Three days' advertisements brought in over six
hundred and fifty applications, and afterward Edison had no trouble in
obtaining all the first-class men he required, as settlers in the artificial
Yosemite he was creating.
We owe to Mr. Mallory a characteristic story of this period as to an
incidental unbending from toil, which in itself illustrates the ever-present
determination to conquer what is undertaken: "Along in the latter part of the
nineties, when the work on the problem of concentrating iron ore was in
progress, it became necessary when leaving the plant at Edison to wait over
at Lake Hopatcong one hour for a connecting train. During some of these
waits Mr. Edison had seen me play billiards. At the particular time this
incident happened, Mrs. Edison and her family were away for the summer,
and I was staying at the Glenmont home on the Orange Mountains.
"One hot Saturday night, after Mr. Edison had looked over the evening
papers, he said to me: 'Do you want to play a game of billiards?' Naturally
this astonished me very much, as he is a man who cares little or nothing for
Edison's due to omit all mention of two hitherto unnamed items in
particular that have added to the world's store of useful devices. We refer
first to the great travelling hoisting-crane having a span of two hundred and
fifteen feet, and used for hoisting loads equal to ten tons, this being the
largest of the kind made up to that time, and afterward used as a model by
many others. The second item was the ingenious and varied forms of
conveyor belt, devised and used by Edison at the concentrating works, and
subsequently developed into a separate and extensive business by an
engineer to whom he gave permission to use his plans and patterns.

Page 331
the ordinary games, with the single exception of parcheesi, of which he is
very fond. I said I would like to play, so we went up into the billiard-room
of the house. I took off the cloth, got out the balls, picked out a cue for Mr.
Edison, and when we banked for the first shot I won and started the game.
After making two or three shots I missed, and a long carom shot was left for
Mr. Edison, the cue ball and object ball being within about twelve inches of
each other, and the other ball a distance of nearly the length of the table. Mr.
Edison attempted to make the shot, but missed it and said 'Put the balls
back.' So I put them back in the same position and he missed it the second
time. I continued at his request to put the balls back in the same position for
the next fifteen minutes, until he could make the shot every time—then he
said: 'I don't want to play any more.'"
Having taken a somewhat superficial survey of the great enterprise under
consideration; having had a cursory glance at the technical development of
the plant up to the point of its successful culmination in the making of a
marketable, commercial product as exemplified in the test at the Crane
Furnace, let us revert to that demonstration and note the events that
followed. The facts of this actual test are far more eloquent than volumes of
argument would be as a justification of Edison's assiduous labors for over
eight years, and of the expenditure of a fortune in bringing his broad
conception to a concrete possibility. In the patient solving of tremendous
problems he had toiled up the mountain-side of success—scaling its
topmost peak and obtaining a view of the boundless prospect. But, alas!
"The best laid plans o' mice and men gang aft agley." The discovery of great
deposits of rich Bessemer ore in the Mesaba range of mountains in
Minnesota a year or two previous to the completion of his work had been
followed by the opening up of those deposits and the marketing of the ore.
It was of such rich character that, being cheaply mined by greatly improved
and inexpensive methods, the market price of crude ore of like iron units
fell from about $6.50 to $3.50 per ton at the time when Edison was ready to
supply his concentrated product. At the former price he could have supplied
the market and earned a liberal profit on his investment, but at $3.50 per ton
he was left without a reasonable chance of competition. Thus was swept
away the possibility of reaping the reward so richly earned by years of
incessant thought, labor, and care. This great and notable plant, representing
a very large outlay of money, brought to completion, ready for business,
and embracing some of the most brilliant and remarkable of Edison's
very fond. I said I would like to play, so we went up into the billiard-room

inventions and methods, must be abandoned by force of circumstances over
which he had no control, and with it must die the high hopes that his
progressive, conquering march to success had legitimately engendered.
The financial aspect of these enterprises is often overlooked and
forgotten. In this instance it was of more than usual import and seriousness,
as Edison was virtually his own "backer," putting into the company almost
the whole of all the fortune his inventions had brought him. There is a
tendency to deny to the capital that thus takes desperate chances its full
reward if things go right, and to insist that it shall have barely the legal rate
of interest and far less than the return of over-the-counter retail trade. It is
an absolute fact that the great electrical inventors and the men who stood
behind them have had little return for their foresight and courage. In this
instance, when the inventor was largely his own financier, the difficulties
and perils were redoubled. Let Mr. Mallory give an instance: "During the
latter part of the panic of 1893 there came a period when we were very hard
up for ready cash, due largely to the panicky conditions; and a large pay-roll
had been raised with considerable difficulty. A short time before pay-day
our treasurer called me up by telephone, and said: 'I have just received the
paid checks from the bank, and I am fearful that my assistant, who has
forged my name to some of the checks, has absconded with about $3000.' I
went immediately to Mr. Edison and told him of the forgery and the amount
of money taken, and in what an embarrassing position we were for the next
pay-roll. When I had finished he said: 'It is too bad the money is gone, but I
will tell you what to do. Go and see the president of the bank which paid the
forged checks. Get him to admit the bank's liability, and then say to him that
Mr. Edison does not think the bank should suffer because he happened to
have a dishonest clerk in his employ. Also say to him that I shall not ask
them to make the amount good.' This was done; the bank admitting its
liability and being much pleased with this action. When I reported to Mr.
Edison he said: 'That's all right. We have made a friend of the bank, and we
may need friends later on.' And so it happened that some time afterward,
when we greatly needed help in the way of loans, the bank willingly gave
us the accommodations we required to tide us over a critical period."
This iron-ore concentrating project had lain close to Edison's heart and
ambition—indeed, it had permeated his whole being to the exclusion of
almost all other investigations or inventions for a while. For five years he
had lived and worked steadily at Edison, leaving there only on Saturday
which he had no control, and with it must die the high hopes that his
progressive, conquering march to success had legitimately engendered.

This iron-ore concentrating project had lain close to Edison's heart and
ambition—indeed, it had permeated his whole being to the exclusion of
almost all other investigations or inventions for a while. For five years he
had lived and worked steadily at Edison, leaving there only on Saturday
Page 333
night to spend Sunday at his home in Orange, and returning to the plant by
an early train on Monday morning. Life at Edison was of the simple kind—
work, meals, and a few hours' sleep—day by day. The little village, called
into existence by the concentrating works, was of the most primitive nature
and offered nothing in the way of frivolity or amusement. Even the scenery
is austere. Hence Edison was enabled to follow his natural bent in being
surrounded day and night by his responsible chosen associates, with whom
he worked uninterrupted by outsiders from early morning away into the late
hours of the evening. Those who were laboring with him, inspired by his
unflagging enthusiasm, followed his example and devoted all their long
waking hours to the furtherance of his plans with a zeal that ultimately bore
fruit in the practical success here recorded.
In view of its present status, this colossal enterprise at Edison may well
be likened to the prologue of a play that is to be subsequently enacted for
the benefit of future generations, but before ringing down the curtain it is
desirable to preserve the unities by quoting the words of one of the principal
actors, Mr. Mallory, who says: "The Concentrating Works had been in
operation, and we had produced a considerable quantity of the briquettes,
and had been able to sell only a portion of them, the iron market being in
such condition that blast-furnaces were not making any new purchases of
iron ore, and were having difficulty to receive and consume the ores which
had been previously contracted for, so what sales we were able to make
were at extremely low prices, my recollection being that they were between
$3.50 and $3.80 per ton, whereas when the works had started we had hoped
to obtain $6.00 to $6.50 per ton for the briquettes. We had also thoroughly
investigated the wonderful deposit at Mesaba, and it was with the greatest
possible reluctance that Mr. Edison was able to come finally to the
conclusion that, under existing conditions, the concentrating plant could not
then be made a commercial success. This decision was reached only after
the most careful investigations and calculations, as Mr. Edison was just as
full of fight and ambition to make it a success as when he first started.
"When this decision was reached Mr. Edison and I took the Jersey
Central train from Edison, bound for Orange, and I did not look forward to
the immediate future with any degree of confidence, as the concentrating
plant was heavily in debt, without any early prospect of being able to pay
off its indebtedness. On the train the matter of the future was discussed, and
Mr. Edison said that, inasmuch as we had the knowledge gained from our
an early train on Monday morning. Life at Edison was of the simple kind—
work, meals, and a few hours' sleep—day by day. The little village, called

plant was heavily in debt, without any early prospect of being able to pay
off its indebtedness. On the train the matter of the future was discussed, and
Mr. Edison said that, inasmuch as we had the knowledge gained from our
Page 334
experience in the concentrating problem, we must, if possible, apply it to
some practical use, and at the same time we must work out some other
plans by which we could make enough money to pay off the Concentrating
Company's indebtedness, Mr. Edison stating most positively that no
company with which he had personally been actively connected had ever
failed to pay its debts, and he did not propose to have the Concentrating
Company any exception.
"In the discussion that followed he suggested several kinds of work
which he had in his mind, and which might prove profitable. We figured
carefully over the probabilities of financial returns from the Phonograph
Works and other enterprises, and after discussing many plans, it was finally
decided that we would apply the knowledge we had gained in the
concentrating plant by building a plant for manufacturing Portland cement,
and that Mr. Edison would devote his attention to the developing of a
storage battery which did not use lead and sulphuric acid. So these two lines
of work were taken up by Mr. Edison with just as much enthusiasm and
energy as is usual with him, the commercial failure of the concentrating
plant seeming not to affect his spirits in any way. In fact, I have often been
impressed strongly with the fact that, during the dark days of the
concentrating problem, Mr. Edison's desire was very strong that the
creditors of the Concentrating Works should be paid in full; and only once
did I hear him make any reference to the financial loss which he himself
made, and he then said: 'As far as I am concerned, I can any time get a job
at $75 per month as a telegrapher, and that will amply take care of all my
personal requirements.' As already stated, however, he started in with the
maximum amount of enthusiasm and ambition, and in the course of about
three years we succeeded in paying off all the indebtedness of the
Concentrating Works, which amounted to several hundred thousand dollars.
"As to the state of Mr. Edison's mind when the final decision was reached
to close down, if he was specially disappointed, there was nothing in his
manner to indicate it, his every thought being for the future, and as to what
could be done to pull us out of the financial situation in which we found
ourselves, and to take advantage of the knowledge which we had acquired
at so great a cost."
It will have been gathered that the funds for this great experiment were
furnished largely by Edison. In fact, over two million dollars were spent in
some practical use, and at the same time we must work out some other
plans by which we could make enough money to pay off the Concentrating
Company's indebtedness, Mr. Edison stating most positively that no
company with which he had personally been actively connected had ever

Page 335
the attempt. Edison's philosophic view of affairs is given in the following
anecdote from Mr. Mallory: "During the boom times of 1902, when the old
General Electric stock sold at its high-water mark of about $330, Mr.
Edison and I were on our way from the cement plant at New Village, New
Jersey, to his home at Orange. When we arrived at Dover, New Jersey, we
got a New York newspaper, and I called his attention to the quotation of that
day on General Electric. Mr. Edison then asked: 'If I hadn't sold any of
mine, what would it be worth to-day?' and after some figuring I replied:
'Over four million dollars.' When Mr. Edison is thinking seriously over a
problem he is in the habit of pulling his right eyebrow, which he did now
for fifteen or twenty seconds. Then his face lighted up, and he said: 'Well,
it's all gone, but we had a hell of a good time spending it.'" With which
revelation of an attitude worthy of Mark Tapley himself, this chapter may
well conclude.

CHAPTER XX
EDISON PORTLAND CEMENT
NEW developments in recent years have been more striking than the
general adoption of cement for structural purposes of all kinds in the United
States; or than the increase in its manufacture here. As a material for the
construction of office buildings, factories, and dwellings, it has lately
enjoyed an extraordinary vogue; yet every indication is confirmatory of the
belief that such use has barely begun. Various reasons may be cited, such as
the growing scarcity of wood, once the favorite building material in many
parts of the country, and the increasing dearness of brick and stone. The fact
remains, indisputable, and demonstrated flatly by the statistics of
production. In 1902 the American output of cement was placed at about
21,000,000 barrels, valued at over $17,000,000. In 1907 the production is
given as nearly 49,000,000 barrels. Here then is an industry that doubled in
five years. The average rate of industrial growth in the United States is 10
per cent. a year, or doubling every ten years. It is a singular fact that
electricity also so far exceeds the normal rate as to double in value and
quantity of output and investment every five years. There is perhaps more
than ordinary coincidence in the association of Edison with two such active
departments of progress.
As a purely manufacturing business the general cement industry is one of
even remote antiquity, and if Edison had entered into it merely as a
commercial enterprise by following paths already so well trodden, the fact
would hardly have been worthy of even passing notice. It is not in his
nature, however, to follow a beaten track except in regard to the recognition
of basic principles; so that while the manufacture of Edison Portland
cement embraces the main essentials and familiar processes of cement-
making, such as crushing, drying, mixing, roasting, and grinding, his
versatility and originality, as exemplified in the conception and introduction
of some bold and revolutionary methods and devices, have resulted in
raising his plant from the position of an outsider to the rank of the fifth

departments of progress.
As a purely manufacturing business the general cement industry is one of
even remote antiquity, and if Edison had entered into it merely as a
commercial enterprise by following paths already so well trodden, the fact
would hardly have been worthy of even passing notice. It is not in his
nature, however, to follow a beaten track except in regard to the recognition
of basic principles; so that while the manufacture of Edison Portland
cement embraces the main essentials and familiar processes of cement-
making, such as crushing, drying, mixing, roasting, and grinding, his
versatility and originality, as exemplified in the conception and introduction
of some bold and revolutionary methods and devices, have resulted in
raising his plant from the position of an outsider to the rank of the fifth
Page 338
largest producer in the United States, in the short space of five years after
starting to manufacture.
Long before his advent in cement production, Edison had held very
pronounced views on the value of that material as the one which would
obtain largely for future building purposes on account of its stability. More
than twenty-five years ago one of the writers of this narrative heard him
remark during a discussion on ancient buildings: "Wood will rot, stone will
chip and crumble, bricks disintegrate, but a cement and iron structure is
apparently indestructible. Look at some of the old Roman baths. They are as
solid as when they were built." With such convictions, and the vast fund of
practical knowledge and experience he had gained at Edison in the crushing
and manipulation of large masses of magnetic iron ore during the preceding
nine years, it is not surprising that on that homeward railway journey,
mentioned at the close of the preceding chapter, he should have decided to
go into the manufacture of cement, especially in view of the enormous
growth of its use for structural purposes during recent times.
The field being a new one to him, Edison followed his usual course of
reading up every page of authoritative literature on the subject, and seeking
information from all quarters. In the mean time, while he was busy also
with his new storage battery, Mr. Mallory, who had been hard at work on
the cement plan, announced that he had completed arrangements for
organizing a company with sufficient financial backing to carry on the
business; concluding with the remark that it was now time to engage
engineers to lay out the plant. Edison replied that he intended to do that
himself, and invited Mr. Mallory to go with him to one of the draughting-
rooms on an upper floor of the laboratory.
Here he placed a large sheet of paper on a draughting-table, and
immediately began to draw out a plan of the proposed works, continuing all
day and away into the evening, when he finished; thus completing within
the twenty-four hours the full lay-out of the entire plant as it was
subsequently installed, and as it has substantially remained in practical use
to this time. It will be granted that this was a remarkable engineering feat,
especially in view of the fact that Edison was then a new-comer in the
cement business, and also that if the plant were to be rebuilt to-day, no vital
change would be desirable or necessary. In that one day's planning every
part was considered and provided for, from the crusher to the packing-
starting to manufacture.

apparently indestructible. Look at some of the old Roman baths. They are as
solid as when they were built." With such convictions, and the vast fund of
practical knowledge and experience he had gained at Edison in the crushing
and manipulation of large masses of magnetic iron ore during the preceding
nine years, it is not surprising that on that homeward railway journey,
mentioned at the close of the preceding chapter, he should have decided to
go into the manufacture of cement, especially in view of the enormous
growth of its use for structural purposes during recent times.
The field being a new one to him, Edison followed his usual course of
reading up every page of authoritative literature on the subject, and seeking
information from all quarters. In the mean time, while he was busy also
with his new storage battery, Mr. Mallory, who had been hard at work on
the cement plan, announced that he had completed arrangements for
organizing a company with sufficient financial backing to carry on the
business; concluding with the remark that it was now time to engage
engineers to lay out the plant. Edison replied that he intended to do that
himself, and invited Mr. Mallory to go with him to one of the draughting-
rooms on an upper floor of the laboratory.
Here he placed a large sheet of paper on a draughting-table, and
immediately began to draw out a plan of the proposed works, continuing all
day and away into the evening, when he finished; thus completing within
the twenty-four hours the full lay-out of the entire plant as it was
subsequently installed, and as it has substantially remained in practical use
to this time. It will be granted that this was a remarkable engineering feat,
especially in view of the fact that Edison was then a new-comer in the
cement business, and also that if the plant were to be rebuilt to-day, no vital
change would be desirable or necessary. In that one day's planning every
part was considered and provided for, from the crusher to the packing-
Page 339
house. From one end to the other, the distance over which the plant
stretches in length is about half a mile, and through the various buildings
spread over this space there passes, automatically, in course of treatment, a
vast quantity of material resulting in the production of upward of two and a
quarter million pounds of finished cement every twenty-four hours, seven
days in the week.
In that one day's designing provision was made not only for all important
parts, but minor details, such, for instance, as the carrying of all steam,
water, and air pipes, and electrical conductors in a large subway running
from one end of the plant to the other; and, an oiling system for the entire
works. This latter deserves special mention, not only because of its
arrangement for thorough lubrication, but also on account of the resultant
economy affecting the cost of manufacture.
Edison has strong convictions on the liberal use of lubricants, but argued
that in the ordinary oiling of machinery there is great waste, while much
dirt is conveyed into the bearings. He therefore planned a system by which
the ten thousand bearings in the plant are oiled automatically; requiring the
services of only two men for the entire work. This is accomplished by a
central pumping and filtering plant and the return of the oil from all parts of
the works by gravity. Every bearing is made dust-proof, and is provided
with two interior pipes. One is above and the other below the bearing. The
oil flows in through the upper pipe, and, after lubricating the shaft, flows
out through the lower pipe back to the pumping station, where any dirt is
filtered out and the oil returned to circulation. While this system of oiling is
not unique, it was the first instance of its adaptation on so large and
complete a scale, and illustrates the far-sightedness of his plans.
In connection with the adoption of this lubricating system there occurred
another instance of his knowledge of materials and intuitive insight into the
nature of things. He thought that too frequent circulation of a comparatively
small quantity of oil would, to some extent, impair its lubricating qualities,
and requested his assistants to verify this opinion by consultation with
competent authorities. On making inquiry of the engineers of the Standard
Oil Company, his theory was fully sustained. Hence, provision was made
for carrying a large stock of oil, and for giving a certain period of rest to
that already used.

A keen appreciation of ultimate success in the production of a fine
quality of cement led Edison to provide very carefully in his original
scheme for those details that he foresaw would become requisite—such, for
instance, as ample stock capacity for raw materials and their automatic
delivery in the various stages of manufacture, as well as mixing, weighing,
and frequent sampling and analyzing during the progress through the mills.
This provision even included the details of the packing-house, and his
perspicacity in this case is well sustained from the fact that nine years
afterward, in anticipation of building an additional packing-house, the
company sent a representative to different parts of the country to examine
the systems used by manufacturers in the packing of large quantities of
various staple commodities involving somewhat similar problems, and
found that there was none better than that devised before the cement plant
was started. Hence, the order was given to build the new packing-house on
lines similar to those of the old one.
Among the many innovations appearing in this plant are two that stand
out in bold relief as indicating the large scale by which Edison measures his
ideas. One of these consists of the crushing and grinding machinery, and the
other of the long kilns. In the preceding chapter there has been given a
description of the giant rolls, by means of which great masses of rock, of
which individual pieces may weigh eight or more tons, are broken and
reduced to about a fourteen-inch size. The economy of this is apparent
when it is considered that in other cement plants the limit of crushing ability
is "one-man size"—that is, pieces not too large for one man to lift.
The story of the kiln, as told by Mr. Mallory, is illustrative of Edison's
tendency to upset tradition and make a radical departure from generally
accepted ideas. "When Mr. Edison first decided to go into the cement
business, it was on the basis of his crushing-rolls and air separation, and he
had every expectation of installing duplicates of the kilns which were then
in common use for burning cement. These kilns were usually made of boiler
iron, riveted, and were about sixty feet long and six feet in diameter, and
had a capacity of about two hundred barrels of cement clinker in twenty-
four hours.
"When the detail plans for our plant were being drawn, Mr. Edison and I
figured over the coal capacity and coal economy of the sixty-foot kiln, and
each time thought that both could he materially bettered. After having gone

each time thought that both could he materially bettered. After having gone
Page 341
over this matter several times, he said: 'I believe I can make a kiln which
will give an output of one thousand barrels in twenty-four hours.' Although
I had then been closely associated with him for ten years and was
accustomed to see him accomplish great things, I could not help feeling the
improbability of his being able to jump into an old-established industry—as
a novice—and start by improving the 'heart' of the production so as to
increase its capacity 400 per cent. When I pressed him for an explanation,
he was unable to give any definite reasons, except that he felt positive it
could be done. In this connection let me say that very many times I have
heard Mr. Edison make predictions as to what a certain mechanical device
ought to do in the way of output and costs, when his statements did not
seem to be even among the possibilities. Subsequently, after more or less
experience, these predictions have been verified, and I cannot help coming
to the conclusion that he has a faculty, not possessed by the average mortal,
of intuitively and correctly sizing up mechanical and commercial
possibilities.
"But, returning to the kiln, Mr. Edison went to work immediately and
very soon completed the design of a new type which was to be one hundred
and fifty feet long and nine feet in diameter, made up in ten-foot sections of
cast iron bolted together and arranged to be revolved on fifteen bearings. He
had a wooden model made and studied it very carefully, through a series of
experiments. These resulted so satisfactorily that this form was finally
decided upon, and ultimately installed as part of the plant.
"Well, for a year or so the kiln problem was a nightmare to me. When we
started up the plant experimentally, and the long kiln was first put in
operation, an output of about four hundred barrels in twenty-four hours was
obtained. Mr. Edison was more than disappointed at this result. His terse
comment on my report was: 'Rotten. Try it again.' When we became a little
more familiar with the operation of the kiln we were able to get the output
up to about five hundred and fifty barrels, and a little later to six hundred
and fifty barrels per day. I would go down to Orange and report with a great
deal of satisfaction the increase in output, but Mr. Edison would apparently
be very much disappointed, and often said to me that the trouble was not
with the kiln, but with our method of operating it; and he would reiterate his
first statement that it would make one thousand barrels in twenty-four

"Each time I would return to the plant with the determination to increase
the output if possible, and we did increase it to seven hundred and fifty,
then to eight hundred and fifty barrels. Every time I reported these increases
Mr. Edison would still be disappointed. I said to him several times that if he
was so sure the kiln could turn out one thousand barrels in twenty-four
hours we would be very glad to have him tell us how to do it, and that we
would run it in any way he directed. He replied that he did not know what it
was that kept the output down, but he was just as confident as ever that the
kiln would make one thousand barrels per day, and that if he had time to
work with and watch the kiln it would not take him long to find out the
reasons why. He had made a number of suggestions throughout these
various trials, however, and, as we continued to operate, we learned
additional points in handling, and were able to get the output up to nine
hundred barrels, then one thousand, and finally to over eleven hundred
barrels per day, thus more than realizing the prediction made by Mr. Edison
before even the plans were drawn. It is only fair to say, however, that
prolonged experience has led us to the conclusion that the maximum
economy in continuous operation of these kilns is obtained by working
them at a little less than their maximum capacity.
"It is interesting to note, in connection with the Edison type of kiln, that
when the older cement manufacturers first learned of it, they ridiculed the
idea universally, and were not slow to predict our early 'finish' as cement
manufacturers. The ultimate success of the kiln, however, proved their
criticisms to be unwarranted. Once aware of its possibility, some of the
cement manufacturers proceeded to avail themselves of the innovation (at
first without Mr. Edison's consent), and to-day more than one-half of the
Portland cement produced in this country is made in kilns of the Edison
type. Old plants are lengthening their kilns wherever practicable, and no
wide-awake manufacturer building a modern plant could afford to install
other than these long kilns. This invention of Mr. Edison has been
recognized by the larger cement manufacturers, and there is every prospect
now that the entire trade will take licenses under his kiln patents."
When he decided to go into the cement business, Edison was thoroughly
awake to the fact that he was proposing to "butt into" an old-established
industry, in which the principal manufacturers were concerns of long
standing. He appreciated fully its inherent difficulties, not only in
manufacture, but also in the marketing of the product. These considerations,

manufacture, but also in the marketing of the product. These considerations,
Page 343
together with his long-settled principle of striving always to make the best,
induced him at the outset to study methods of producing the highest quality
of product. Thus he was led to originate innovations in processes, some of
which have been preserved as trade secrets; but of the others there are two
deserving special notice—namely, the accuracy of mixing and the fineness
of grinding.
In cement-making, generally speaking, cement rock and limestone in the
rough are mixed together in such relative quantities as may be determined
upon in advance by chemical analysis. In many plants this mixture is made
by barrow or load units, and may be more or less accurate. Rule-of-thumb
methods are never acceptable to Edison, and he devised therefore a system
of weighing each part of the mixture, so that it would be correct to a pound,
and, even at that, made the device "fool-proof," for as he observed to one of
his associates: "The man at the scales might get to thinking of the other
fellow's best girl, so fifty or a hundred pounds of rock, more or less,
wouldn't make much difference to him." The Edison checking plan
embraces two hoppers suspended above two platform scales whose beams
are electrically connected with a hopper-closing device by means of needles
dipping into mercury cups. The scales are set according to the chemist's
weighing orders, and the material is fed into the scales from the hoppers.
The instant the beam tips, the connection is broken and the feed stops
instantly, thus rendering it impossible to introduce any more material until
the charge has been unloaded.
The fine grinding of cement clinker is distinctively Edisonian in both
origin and application. As has been already intimated, its author followed a
thorough course of reading on the subject long before reaching the actual
projection or installation of a plant, and he had found all authorities to agree
on one important point—namely, that the value of cement depends upon the
fineness to which it is ground. [16] He also ascertained that in the trade the
standard of fineness was that 75 per cent. of the whole mass would pass
through a 200-mesh screen. Having made some improvements in his
grinding and screening apparatus, and believing that in the future engineers,
builders, and contractors would eventually require a higher degree of
fineness, he determined, in advance of manufacturing, to raise the standard
ten points, so that at least 85 per cent. of his product should pass through a
200-mesh screen. This was a bold step to be taken by a new-comer, but his
judgment, backed by a full confidence in ability to live up to this standard,
induced him at the outset to study methods of producing the highest quality
of product. Thus he was led to originate innovations in processes, some of
which have been preserved as trade secrets; but of the others there are two

has been fully justified in its continued maintenance, despite the early
incredulity of older manufacturers as to the possibility of attaining such a
high degree of fineness.
[Footnote 16: For a proper understanding and full
appreciation of the importance of fine grinding, it may be
explained that Portland cement (as manufactured in the
Lehigh Valley) is made from what is commonly spoken of as
"cement rock," with the addition of sufficient limestone to
give the necessary amount of lime. The rock is broken down
and then ground to a fineness of 80 to 90 per cent. through
a 200-mesh screen. This ground material passes through kilns
and comes out in "clinker." This is ground and that part of
this finely ground clinker that will pass a 200-mesh screen
is cement; the residue is still clinker. These coarse
particles, or clinkers, absorb water very slowly, are
practically inert, and have very feeble cementing
properties. The residue on a 200-mesh screen is useless.]
If Edison measured his happiness, as men often do, by merely
commercial or pecuniary rewards of success, it would seem almost
redundant to state that he has continued to manifest an intense interest in the
cement plant. Ordinarily, his interest as an inventor wanes in proportion to
the approach to mere commercialism—in other words, the keenness of his
pleasure is in overcoming difficulties rather than the mere piling up of a
bank account. He is entirely sensible of the advantages arising from a good
balance at the banker's, but that has not been the goal of his ambition.
Hence, although his cement enterprise reached the commercial stage a long
time ago, he has been firmly convinced of his own ability to devise still
further improvements and economical processes of greater or less
fundamental importance, and has, therefore, made a constant study of the
problem as a whole and in all its parts. By means of frequent reports, aided
by his remarkable memory, he keeps in as close touch with the plant as if he
were there in person every day, and is thus enabled to suggest improvement
in any particular detail. The engineering force has a great respect for the
accuracy of his knowledge of every part of the plant, for he remembers the
dimensions and details of each item of machinery, sometimes to the
discomfiture of those who are around it every day.
A noteworthy instance of Edison's memory occurred in connection with
this cement plant. Some years ago, as its installation was nearing
completion, he went up to look it over and satisfy himself as to what needed
to be done. On the arrival of the train at 10.40 in the morning, he went to
the mill, and, with Mr. Mason, the general superintendent, started at the
incredulity of older manufacturers as to the possibility of attaining such a
high degree of fineness.

to be done. On the arrival of the train at 10.40 in the morning, he went to
the mill, and, with Mr. Mason, the general superintendent, started at the
Page 345
crusher at one end, and examined every detail all the way through to the
packing-house at the other end. He made neither notes nor memoranda, but
the examination required all the day, which happened to be a Saturday. He
took a train for home at 5.30 in the afternoon, and on arriving at his
residence at Orange, got out some note-books and began to write entirely
from memory each item consecutively. He continued at this task all through
Saturday night, and worked steadily on until Sunday afternoon, when he
completed a list of nearly six hundred items. The nature of this feat is more
appreciable from the fact that a large number of changes included all the
figures of new dimensions he had decided upon for some of the machinery
throughout the plant.
As the reader may have a natural curiosity to learn whether or not the list
so made was practical, it may be stated that it was copied and sent up to the
general superintendent with instructions to make the modifications
suggested, and report by numbers as they were attended to. This was
faithfully done, all the changes being made before the plant was put into
operation. Subsequent experience has amply proven the value of Edison's
prescience at this time.
Although Edison's achievements in the way of improved processes and
machinery have already made a deep impression in the cement industry, it is
probable that this impression will become still more profoundly stamped
upon it in the near future with the exploitation of his "Poured Cement
House." The broad problem which he set himself was to provide handsome
and practically indestructible detached houses, which could be taken by
wage-earners at very moderate monthly rentals. He turned this question
over in his mind for several years, and arrived at the conclusion that a house
cast in one piece would be the answer. To produce such a house involved
the overcoming of many engineering and other technical difficulties. These
he attacked vigorously and disposed of patiently one by one.
In this connection a short anecdote may be quoted from Edison as
indicative of one of the influences turning his thoughts in this direction. In
the story of the ore-milling work, it has been noted that the plant was shut
down owing to the competition of the cheap ore from the Mesaba Range.
Edison says: "When I shut down, the insurance companies cancelled my
insurance. I asked the reason why. 'Oh,' they said, 'this thing is a failure. The

packing-house at the other end. He made neither notes nor memoranda, but
the examination required all the day, which happened to be a Saturday. He
took a train for home at 5.30 in the afternoon, and on arriving at his
residence at Orange, got out some note-books and began to write entirely
from memory each item consecutively. He continued at this task all through
Saturday night, and worked steadily on until Sunday afternoon, when he
completed a list of nearly six hundred items. The nature of this feat is more
appreciable from the fact that a large number of changes included all the
figures of new dimensions he had decided upon for some of the machinery
throughout the plant.
As the reader may have a natural curiosity to learn whether or not the list
so made was practical, it may be stated that it was copied and sent up to the
general superintendent with instructions to make the modifications
suggested, and report by numbers as they were attended to. This was
faithfully done, all the changes being made before the plant was put into
operation. Subsequent experience has amply proven the value of Edison's
prescience at this time.
Although Edison's achievements in the way of improved processes and
machinery have already made a deep impression in the cement industry, it is
probable that this impression will become still more profoundly stamped
upon it in the near future with the exploitation of his "Poured Cement
House." The broad problem which he set himself was to provide handsome
and practically indestructible detached houses, which could be taken by
wage-earners at very moderate monthly rentals. He turned this question
over in his mind for several years, and arrived at the conclusion that a house
cast in one piece would be the answer. To produce such a house involved
the overcoming of many engineering and other technical difficulties. These
he attacked vigorously and disposed of patiently one by one.
In this connection a short anecdote may be quoted from Edison as
indicative of one of the influences turning his thoughts in this direction. In
the story of the ore-milling work, it has been noted that the plant was shut
down owing to the competition of the cheap ore from the Mesaba Range.
Edison says: "When I shut down, the insurance companies cancelled my
insurance. I asked the reason why. 'Oh,' they said, 'this thing is a failure. The
moral risk is too great.' 'All right; I am glad to hear it. I will now construct
Page 346
buildings that won't have any moral risk.' I determined to go into the
Portland cement business. I organized a company and started cement-works
which have now been running successfully for several years. I had so
perfected the machinery in trying to get my ore costs down that the making
of cheap cement was an easy matter to me. I built these works entirely of
concrete and steel, so that there is not a wagon-load of lumber in them; and
so that the insurance companies would not have any possibility of having
any 'moral risk.' Since that time I have put up numerous factory buildings
all of steel and concrete, without any combustible whatever about them—to
avoid this 'moral risk.' I am carrying further the application of this idea in
building private houses for poor people, in which there will be no 'moral
risk' at all—nothing whatever to burn, not even by lightning."
As a casting necessitates a mold, together with a mixture sufficiently
fluid in its nature to fill all the interstices completely, Edison devoted much
attention to an extensive series of experiments for producing a free-flowing
combination of necessary materials. His proposition was against all
precedent. All expert testimony pointed to the fact that a mixture of
concrete (cement, sand, crushed stone, and water) could not be made to
flow freely to the smallest parts of an intricate set of molds; that the heavy
parts of the mixture could not be held in suspension, but would separate out
by gravity and make an unevenly balanced structure; that the surface would
be full of imperfections, etc.
Undeterred by the unanimity of adverse opinions, however, he pursued
his investigations with the thorough minuteness that characterizes all his
laboratory work, and in due time produced a mixture which on elaborate
test overcame all objections and answered the complex requirements
perfectly, including the making of a surface smooth, even, and entirely
waterproof. All the other engineering problems have received study in like
manner, and have been overcome, until at the present writing the whole
question is practically solved and has been reduced to actual practice. The
Edison poured or cast cement house may be reckoned as a reality.
The general scheme, briefly outlined, is to prepare a model and plans of
the house to be cast, and then to design a set of molds in sections of
convenient size. When all is ready, these molds, which are of cast iron with
smooth interior surfaces, are taken to the place where the house is to be
erected. Here there has been provided a solid concrete cellar floor,

smooth interior surfaces, are taken to the place where the house is to be

Page 347
technically called "footing." The molds are then locked together so that they
rest on this footing. Hundreds of pieces are necessary for the complete set.
When they have been completely assembled, there will be a hollow space in
the interior, representing the shape of the house. Reinforcing rods are also
placed in the molds, to be left behind in the finished house.
Next comes the pouring of the concrete mixture into this form. Large
mechanical mixers are used, and, as it is made, the mixture is dumped into
tanks, from which it is conveyed to a distributing tank on the top, or roof, of
the form. From this tank a large number of open troughs or pipes lead the
mixture to various openings in the roof, whence it flows down and fills all
parts of the mold from the footing in the basement until it overflows at the
tip of the roof.
The pouring of the entire house is accomplished in about six hours, and
then the molds are left undisturbed for six days, in order that the concrete
may set and harden. After that time the work of taking away the molds is
begun. This requires three or four days. When the molds are taken away an
entire house is disclosed, cast in one piece, from cellar to tip of roof,
complete with floors, interior walls, stairways, bath and laundry tubs,
electric-wire conduits, gas, water, and heating pipes. No plaster is used
anywhere; but the exterior and interior walls are smooth and may be painted
or tinted, if desired. All that is now necessary is to put in the windows,
doors, heater, and lighting fixtures, and to connect up the plumbing and
heating arrangements, thus making the house ready for occupancy.
As these iron molds are not ephemeral like the wooden framing now used
in cement construction, but of practically illimitable life, it is obvious that
they can be used a great number of times. A complete set of molds will cost
approximately $25,000, while the necessary plant will cost about $15,000
more. It is proposed to work as a unit plant for successful operation at least
six sets of molds, to keep the men busy and the machinery going. Any one,
with a sheet of paper, can ascertain the yearly interest on the investment as a
fixed charge to be assessed against each house, on the basis that one
hundred and forty-four houses can be built in a year with the battery of six
sets of molds. Putting the sum at $175,000, and the interest at 6 per cent. on
the cost of the molds and 4 per cent. for breakage, together with 6 per cent.
interest and 15 per cent. depreciation on machinery, the plant charge is
approximately $140 per house. It does not require a particularly acute
rest on this footing. Hundreds of pieces are necessary for the complete set.

prophetic vision to see "Flower Towns" of "Poured Houses" going up in
whole suburbs outside all our chief centres of population.
Edison's conception of the workingman's ideal house has been a broad
one from the very start. He was not content merely to provide a roomy,
moderately priced house that should be fireproof, waterproof, and vermin-
proof, and practically indestructible, but has been solicitous to get away
from the idea of a plain "packing-box" type. He has also provided for
ornamentation of a high class in designing the details of the structure. As he
expressed it: "We will give the workingman and his family ornamentation
in their house. They deserve it, and besides, it costs no more after the
pattern is made to give decorative effects than it would to make everything
plain." The plans have provided for a type of house that would cost not far
from $30,000 if built of cut stone. He gave to Messrs. Mann & McNaillie,
architects, New York, his idea of the type of house he wanted. On receiving
these plans he changed them considerably, and built a model. After making
many more changes in this while in the pattern shop, he produced a house
satisfactory to himself.
This one-family house has a floor plan twenty-five by thirty feet, and is
three stories high. The first floor is divided off into two large rooms—parlor
and living-room—and the upper floors contain four large bedrooms, a
roomy bath-room, and wide halls. The front porch extends eight feet, and
the back porch three feet. A cellar seven and a half feet high extends under
the whole house, and will contain the boiler, wash-tubs, and coal-bunker. It
is intended that the house shall be built on lots forty by sixty feet, giving a
lawn and a small garden.
It is contemplated that these houses shall be built in industrial
communities, where they can be put up in groups of several hundred. If
erected in this manner, and by an operator buying his materials in large
quantities, Edison believes that these houses can be erected complete,
including heating apparatus and plumbing, for $1200 each. This figure
would also rest on the basis of using in the mixture the gravel excavated on
the site. Comment has been made by persons of artistic taste on the
monotony of a cluster of houses exactly alike in appearance, but this
criticism has been anticipated, and the molds are so made as to be capable
of permutations of arrangement. Thus it will be possible to introduce almost
endless changes in the style of house by variation of the same set of molds.

For more than forty years Edison was avowedly an inventor for purely
commercial purposes; but within the last two years he decided to retire from
that field so far as new inventions were concerned, and to devote himself to
scientific research and experiment in the leisure hours that might remain
after continuing to improve his existing devices. But although the poured
cement house was planned during the commercial period, the spirit in
which it was conceived arose out of an earnest desire to place within the
reach of the wage-earner an opportunity to better his physical, pecuniary,
and mental conditions in so far as that could be done through the medium of
hygienic and beautiful homes at moderate rentals. From the first Edison has
declared that it was not his intention to benefit pecuniarily through the
exploitation of this project. Having actually demonstrated the practicability
and feasibility of his plans, he will allow responsible concerns to carry them
into practice under such limitations as may be necessary to sustain the basic
object, but without any payment to him except for the actual expense
incurred. The hypercritical may cavil and say that, as a manufacturer of
cement, Edison will be benefited. True, but as ANY good Portland cement
can be used, and no restrictions as to source of supply are enforced, he, or
rather his company, will be merely one of many possible purveyors.
This invention is practically a gift to the workingmen of the world and
their families. The net result will be that those who care to avail themselves
of the privilege may, sooner or later, forsake the crowded apartment or
tenement and be comfortably housed in sanitary, substantial, and roomy
homes fitted with modern conveniences, and beautified by artistic
decorations, with no outlay for insurance or repairs; no dread of fire, and all
at a rental which Edison believes will be not more, but probably less than,
$10 per month in any city of the United States. While his achievement in its
present status will bring about substantial and immediate benefits to wage-
earners, his thoughts have already travelled some years ahead in the
formulation of a still further beneficial project looking toward the
individual ownership of these houses on a basis startling in its practical
possibilities.

CHAPTER XXI
MOTION PICTURES
THE preceding chapters have treated of Edison in various aspects as an
inventor, some of which are familiar to the public, others of which are
believed to be in the nature of a novel revelation, simply because no one
had taken the trouble before to put the facts together. To those who have
perhaps grown weary of seeing Edison's name in articles of a sensational
character, it may sound strange to say that, after all, justice has not been
done to his versatile and many-sided nature; and that the mere prosaic facts
of his actual achievement outrun the wildest flights of irrelevant journalistic
imagination. Edison hates nothing more than to be dubbed a genius or
played up as a "wizard"; but this fate has dogged him until he has come at
last to resign himself to it with a resentful indignation only to be
appreciated when watching him read the latest full-page Sunday "spread"
that develops a casual conversation into oracular verbosity, and gives to his
shrewd surmise the cast of inspired prophecy.
In other words, Edison's real work has seldom been seriously discussed.
Rather has it been taken as a point of departure into a realm of fancy and
romance, where as a relief from drudgery he is sometimes quite willing to
play the pipe if some one will dance to it. Indeed, the stories woven around
his casual suggestions are tame and vapid alongside his own essays in
fiction, probably never to be published, but which show what a real
inventor can do when he cuts loose to create a new heaven and a new earth,
unrestrained by any formal respect for existing conditions of servitude to
three dimensions and the standard elements.
The present chapter, essentially technical in its subject-matter, is perhaps
as significant as any in this biography, because it presents Edison as the
Master Impresario of his age, and maybe of many following ages also. His
phonographs and his motion pictures have more audiences in a week than
all the theatres in America in a year. The "Nickelodeon" is the central fact in
modern amusement, and Edison founded it. All that millions know of music
and drama he furnishes; and the whole study of the theatrical managers thus

Master Impresario of his age, and maybe of many following ages also. His
phonographs and his motion pictures have more audiences in a week than

modern amusement, and Edison founded it. All that millions know of music
and drama he furnishes; and the whole study of the theatrical managers thus

reaching the masses is not to ascertain the limitations of the new art, but to
discover its boundless possibilities. None of the exuberant versions of
things Edison has not done could endure for a moment with the simple
narrative of what he has really done as the world's new Purveyor of
Pleasure. And yet it all depends on the toilful conquest of a subtle and
intricate art. The story of the invention of the phonograph has been told.
That of the evolution of motion pictures follows. It is all one piece of sober,
careful analysis, and stubborn, successful attack on the problem.
The possibility of making a record of animate movement, and
subsequently reproducing it, was predicted long before the actual
accomplishment. This, as we have seen, was also the case with the
phonograph, the telephone, and the electric light. As to the phonograph, the
prediction went only so far as the RESULT; the apparent intricacy of the
problem being so great that the MEANS for accomplishing the desired end
were seemingly beyond the grasp of the imagination or the mastery of
invention.
With the electric light and the telephone the prediction included not only
the result to be accomplished, but, in a rough and general way, the
mechanism itself; that is to say, long before a single sound was intelligibly
transmitted it was recognized that such a thing might be done by causing a
diaphragm, vibrated by original sounds, to communicate its movements to a
distant diaphragm by a suitably controlled electric current. In the case of the
electric light, the heating of a conductor to incandescence in a highly
rarefied atmosphere was suggested as a scheme of illumination long before
its actual accomplishment, and in fact before the production of a suitable
generator for delivering electric current in a satisfactory and economical
manner.
It is a curious fact that while the modern art of motion pictures depends
essentially on the development of instantaneous photography, the
suggestion of the possibility of securing a reproduction of animate motion,
as well as, in a general way, of the mechanism for accomplishing the result,
was made many years before the instantaneous photograph became
possible. While the first motion picture was not actually produced until the
summer of 1889, its real birth was almost a century earlier, when Plateau, in
France, constructed an optical toy, to which the impressive name of
"Phenakistoscope" was applied, for producing an illusion of motion. This

France, constructed an optical toy, to which the impressive name of
"Phenakistoscope" was applied, for producing an illusion of motion. This
Page 352
toy in turn was the forerunner of the Zoetrope, or so-called "Wheel of Life,"
which was introduced into this country about the year 1845. These devices
were essentially toys, depending for their successful operation (as is the
case with motion pictures) upon a physiological phenomenon known as
persistence of vision. If, for instance, a bright light is moved rapidly in front
of the eye in a dark room, it appears not as an illuminated spark, but as a
line of fire; a so-called shooting star, or a flash of lightning produces the
same effect. This result is purely physiological, and is due to the fact that
the retina of the eye may be considered as practically a sensitized plate of
relatively slow speed, and an image impressed upon it remains, before
being effaced, for a period of from one-tenth to one-seventh of a second,
varying according to the idiosyncrasies of the individual and the intensity of
the light. When, therefore, it is said that we should only believe things we
actually see, we ought to remember that in almost every instance we never
see things as they are.
Bearing in mind the fact that when an image is impressed on the human
retina it persists for an appreciable period, varying as stated, with the
individual, and depending also upon the intensity of the illumination, it will
be seen that, if a number of pictures or photographs are successively
presented to the eye, they will appear as a single, continuous photograph,
provided the periods between them are short enough to prevent one of the
photographs from being effaced before its successor is presented. If, for
instance, a series of identical portraits were rapidly presented to the eye, a
single picture would apparently be viewed, or if we presented to the eye the
series of photographs of a moving object, each one representing a minute
successive phase of the movement, the movements themselves would
apparently again take place.
With the Zoetrope and similar toys rough drawings were used for
depicting a few broadly outlined successive phases of movement, because
in their day instantaneous photography was unknown, and in addition there
were certain crudities of construction that seriously interfered with the
illumination of the pictures, rendering it necessary to make them practically
as silhouettes on a very conspicuous background. Hence it will be obvious
that these toys produced merely an ILLUSION of THEORETICAL motion.
But with the knowledge of even an illusion of motion, and with the
philosophy of persistence of vision fully understood, it would seem that,

were essentially toys, depending for their successful operation (as is the

instance, a series of identical portraits were rapidly presented to the eye, a
single picture would apparently be viewed, or if we presented to the eye the
series of photographs of a moving object, each one representing a minute
successive phase of the movement, the movements themselves would
apparently again take place.
With the Zoetrope and similar toys rough drawings were used for
depicting a few broadly outlined successive phases of movement, because
in their day instantaneous photography was unknown, and in addition there
were certain crudities of construction that seriously interfered with the
illumination of the pictures, rendering it necessary to make them practically
as silhouettes on a very conspicuous background. Hence it will be obvious
that these toys produced merely an ILLUSION of THEORETICAL motion.
But with the knowledge of even an illusion of motion, and with the
philosophy of persistence of vision fully understood, it would seem that,
Page 353
upon the development of instantaneous photography, the reproduction of
ACTUAL motion by means of pictures would have followed, almost as a
necessary consequence. Yet such was not the case, and success was
ultimately accomplished by Edison only after persistent experimenting
along lines that could not have been predicted, including the construction of
apparatus for the purpose, which, if it had not been made, would
undoubtedly be considered impossible. In fact, if it were not for Edison's
peculiar mentality, that refuses to recognize anything as impossible until
indubitably demonstrated to be so, the production of motion pictures would
certainly have been delayed for years, if not for all time.
One of the earliest suggestions of the possibility of utilizing photography
for exhibiting the illusion of actual movement was made by Ducos, who, as
early as 1864, obtained a patent in France, in which he said: "My invention
consists in substituting rapidly and without confusion to the eye not only of
an individual, but when so desired of a whole assemblage, the enlarged
images of a great number of pictures when taken instantaneously and
successively at very short intervals.... The observer will believe that he sees
only one image, which changes gradually by reason of the successive
changes of form and position of the objects which occur from one picture to
the other. Even supposing that there be a slight interval of time during
which the same object was not shown, the persistence of the luminous
impression upon the eye will fill this gap. There will be as it were a living
representation of nature and . . . the same scene will be reproduced upon the
screen with the same degree of animation.... By means of my apparatus I
am enabled especially to reproduce the passing of a procession, a review of
military manoeuvres, the movements of a battle, a public fete, a theatrical
scene, the evolution or the dances of one or of several persons, the changing
expression of countenance, or, if one desires, the grimaces of a human face;
a marine view, the motion of waves, the passage of clouds in a stormy sky,
particularly in a mountainous country, the eruption of a volcano," etc.
Other dreamers, contemporaries of Ducos, made similar suggestions;
they recognized the scientific possibility of the problem, but they were
irretrievably handicapped by the shortcomings of photography. Even when
substantially instantaneous photographs were evolved at a somewhat later
date they were limited to the use of wet plates, which have to be prepared
by the photographer and used immediately, and were therefore quite out of
the question for any practical commercial scheme. Besides this, the use of
ACTUAL motion by means of pictures would have followed, almost as a
necessary consequence. Yet such was not the case, and success was

Page 354
plates would have been impracticable, because the limitations of their
weight and size would have prevented the taking of a large number of
pictures at a high rate of speed, even if the sensitized surface had been
sufficiently rapid.
Nothing ever came of Ducos' suggestions and those of the early dreamers
in this essentially practical and commercial art, and their ideas have made
no greater impress upon the final result than Jules Verne's Nautilus of our
boyhood days has developed the modern submarine. From time to time
further suggestions were made, some in patents, and others in photographic
and scientific publications, all dealing with the fascinating thought of
preserving and representing actual scenes and events. The first serious
attempt to secure an illusion of motion by photography was made in 1878
by Edward Muybridge as a result of a wager with the late Senator Leland
Stanford, the California pioneer and horse-lover, who had asserted, contrary
to the usual belief, that a trotting-horse at one point in its gait left the
ground entirely. At this time wet plates of very great rapidity were known,
and by arranging a series of cameras along the line of a track and causing
the horse in trotting past them, by striking wires or strings attached to the
shutters, to actuate the cameras at the right instant, a series of very clear
instantaneous photographs was obtained. From these negatives, when
developed, positive prints were made, which were later mounted on a
modified form of Zoetrope and projected upon a screen.
One of these early exhibitions is described in the Scientific American of
June 5, 1880: "While the separate photographs had shown the successive
positions of a trotting or running horse in making a single stride, the
Zoogyroscope threw upon the screen apparently the living animal. Nothing
was wanting but the clatter of hoofs upon the turf, and an occasional breath
of steam from the nostrils, to make the spectator believe that he had before
him genuine flesh-and-blood steeds. In the views of hurdle-leaping, the
simulation was still more admirable, even to the motion of the tail as the
animal gathered for the jump, the raising of his head, all were there. Views
of an ox trotting, a wild bull on the charge, greyhounds and deer running
and birds flying in mid-air were shown, also athletes in various positions."
It must not be assumed from this statement that even as late as the work of
Muybridge anything like a true illusion of movement had been obtained,
because such was not the case. Muybridge secured only one cycle of
movement, because a separate camera had to be used for each photograph
weight and size would have prevented the taking of a large number of
pictures at a high rate of speed, even if the sensitized surface had been
sufficiently rapid.

Muybridge anything like a true illusion of movement had been obtained,
because such was not the case. Muybridge secured only one cycle of
movement, because a separate camera had to be used for each photograph
Page 355
and consequently each cycle was reproduced over and over again. To have
made photographs of a trotting-horse for one minute at the moderate rate of
twelve per second would have required, under the Muybridge scheme,
seven hundred and twenty separate cameras, whereas with the modern art
only a single camera is used. A further defect with the Muybridge pictures
was that since each photograph was secured when the moving object was in
the centre of the plate, the reproduction showed the object always centrally
on the screen with its arms or legs in violent movement, but not making any
progress, and with the scenery rushing wildly across the field of view!
In the early 80's the dry plate was first introduced into general use, and
from that time onward its rapidity and quality were gradually improved; so
much so that after 1882 Prof. E. J. Marey, of the French Academy, who in
1874 had published a well-known treatise on "Animal Movement," was
able by the use of dry plates to carry forward the experiments of Muybridge
on a greatly refined scale. Marey was, however, handicapped by reason of
the fact that glass plates were still used, although he was able with a single
camera to obtain twelve photographs on successive plates in the space of
one second. Marey, like Muybridge, photographed only one cycle of the
movements of a single object, which was subsequently reproduced over and
over again, and the camera was in the form of a gun, which could follow the
object so that the successive pictures would be always located in the centre
of the plates.
The review above given, as briefly as possible, comprises substantially
the sum of the world's knowledge at the time the problem of recording and
reproducing animate movement was first undertaken by Edison. The most
that could be said of the condition of the art when Edison entered the field
was that it had been recognized that if a series of instantaneous photographs
of a moving object could be secured at an enormously high rate many times
per second—they might be passed before the eye either directly or by
projection upon a screen, and thereby result in a reproduction of the
movements. Two very serious difficulties lay in the way of actual
accomplishment, however—first, the production of a sensitive surface in
such form and weight as to be capable of being successively brought into
position and exposed, at the necessarily high rate; and, second, the
production of a camera capable of so taking the pictures. There were
numerous other workers in the field, but they added nothing to what had
already been proposed. Edison himself knew nothing of Ducos, or that the
made photographs of a trotting-horse for one minute at the moderate rate of
twelve per second would have required, under the Muybridge scheme,
seven hundred and twenty separate cameras, whereas with the modern art
only a single camera is used. A further defect with the Muybridge pictures

suggestions had advanced beyond the single centrally located photographs
of Muybridge and Marey. As a matter of public policy, the law presumes
that an inventor must be familiar with all that has gone before in the field
within which he is working, and if a suggestion is limited to a patent
granted in New South Wales, or is described in a single publication in
Brazil, an inventor in America, engaged in the same field of thought, is by
legal fiction presumed to have knowledge not only of the existence of that
patent or publication, but of its contents. We say this not in the way of an
apology for the extent of Edison's contribution to the motion-picture art,
because there can be no question that he was as much the creator of that art
as he was of the phonographic art; but to show that in a practical sense the
suggestion of the art itself was original with him. He himself says: "In the
year 1887 the idea occurred to me that it was possible to devise an
instrument which should do for the eye what the phonograph does for the
ear, and that by a combination of the two, all motion and sound could be
recorded and reproduced simultaneously. This idea, the germ of which came
from the little toy called the Zoetrope and the work of Muybridge, Marey,
and others, has now been accomplished, so that every change of facial
expression can be recorded and reproduced life-size. The kinetoscope is
only a small model illustrating the present stage of the progress, but with
each succeeding month new possibilities are brought into view. I believe
that in coming years, by my own work and that of Dickson, Muybridge,
Marey, and others who will doubtless enter the field, grand opera can be
given at the Metropolitan Opera House at New York without any material
change from the original, and with artists and musicians long since dead."
In the earliest experiments attempts were made to secure the
photographs, reduced microscopically, arranged spirally on a cylinder about
the size of a phonograph record, and coated with a highly sensitized
surface, the cylinder being given an intermittent movement, so as to be at
rest during each exposure. Reproductions were obtained in the same way,
positive prints being observed through a magnifying glass. Various forms of
apparatus following this general type were made, but they were all open to
the serious objection that the very rapid emulsions employed were
relatively coarse-grained and prevented the securing of sharp pictures of
microscopic size. On the other hand, the enlarging of the apparatus to
permit larger pictures to be obtained would present too much weight to be
stopped and started with the requisite rapidity. In these early experiments,

however, it was recognized that, to secure proper results, a single camera
should be used, so that the objects might move across its field just as they
move across the field of the human eye; and the important fact was also
observed that the rate at which persistence of vision took place represented
the minimum speed at which the pictures should be obtained. If, for
instance, five pictures per second were taken (half of the time being
occupied in exposure and the other half in moving the exposed portion of
the film out of the field of the lens and bringing a new portion into its
place), and the same ratio is observed in exhibiting the pictures, the interval
of time between successive pictures would be one-tenth of a second; and for
a normal eye such an exhibition would present a substantially continuous
photograph. If the angular movement of the object across the field is very
slow, as, for instance, a distant vessel, the successive positions of the object
are so nearly coincident that when reproduced before the eye an impression
of smooth, continuous movement is secured. If, however, the object is
moving rapidly across the field of view, one picture will be separated from
its successor to a marked extent, and the resulting impression will be jerky
and unnatural. Recognizing this fact, Edison always sought for a very high
speed, so as to give smooth and natural reproductions, and even with his
experimental apparatus obtained upward of forty-eight pictures per second,
whereas, in practice, at the present time, the accepted rate varies between
twenty and thirty per second. In the efforts of the present day to economize
space by using a minimum length of film, pictures are frequently taken at
too slow a rate, and the reproductions are therefore often objectionable, by
reason of more or less jerkiness.
During the experimental period and up to the early part of 1889, the
kodak film was being slowly developed by the Eastman Kodak Company.
Edison perceived in this product the solution of the problem on which he
had been working, because the film presented a very light body of tough
material on which relatively large photographs could be taken at rapid
intervals. The surface, however, was not at first sufficiently sensitive to
admit of sharply defined pictures being secured at the necessarily high
rates. It seemed apparent, therefore, that in order to obtain the desired speed
there would have to be sacrificed that fineness of emulsion necessary for
the securing of sharp pictures. But as was subsequently seen, this sacrifice
was in time rendered unnecessary. Much credit is due the Eastman experts
—stimulated and encouraged by Edison, but independently of him—for the

move across the field of the human eye; and the important fact was also
observed that the rate at which persistence of vision took place represented

Page 358
production at last of a highly sensitized, fine-grained emulsion presenting
the highly sensitized surface that Edison sought.
Having at last obtained apparently the proper material upon which to
secure the photographs, the problem then remained to devise an apparatus
by means of which from twenty to forty pictures per second could be taken;
the film being stationary during the exposure and, upon the closing of the
shutter, being moved to present a fresh surface. In connection with this
problem it is interesting to note that this question of high speed was
apparently regarded by all Edison's predecessors as the crucial point.
Ducos, for example, expended a great deal of useless ingenuity in devising
a camera by means of which a tape-line film could receive the photographs
while being in continuous movement, necessitating the use of a series of
moving lenses. Another experimenter, Dumont, made use of a single large
plate and a great number of lenses which were successively exposed.
Muybridge, as we have seen, used a series of cameras, one for each plate.
Marey was limited to a very few photographs, because the entire surface
had to be stopped and started in connection with each exposure.
After the accomplishment of the fact, it would seem to be the obvious
thing to use a single lens and move the sensitized film with respect to it,
intermittently bringing the surface to rest, then exposing it, then cutting off
the light and moving the surface to a fresh position; but who, other than
Edison, would assume that such a device could be made to repeat these
movements over and over again at the rate of twenty to forty per second?
Users of kodaks and other forms of film cameras will appreciate perhaps
better than others the difficulties of the problem, because in their work, after
an exposure, they have to advance the film forward painfully to the extent
of the next picture before another exposure can take place, these operations
permitting of speeds of but a few pictures per minute at best. Edison's
solution of the problem involved the production of a kodak in which from
twenty to forty pictures should be taken IN EACH SECOND, and with such
fineness of adjustment that each should exactly coincide with its
predecessors even when subjected to the test of enlargement by projection.
This, however, was finally accomplished, and in the summer of 1889 the
first modern motion-picture camera was made. More than this, the
mechanism for operating the film was so constructed that the movement of
the film took place in one-tenth of the time required for the exposure,
giving the film an opportunity to come to rest prior to the opening of the
the highly sensitized surface that Edison sought.

standard for securing pictures of objects in motion, and such changes as
have been made in it have been purely in the nature of detail mechanical
refinements.
The earliest form of exhibiting apparatus, known as the Kinetoscope, was
a machine in which a positive print from the negative obtained in the
camera was exhibited directly to the eye through a peep-hole; but in 1895
the films were applied to modified forms of magic lanterns, by which the
images are projected upon a screen. Since that date the industry has
developed very rapidly, and at the present time (1910) all of the principal
American manufacturers of motion pictures are paying a royalty to Edison
under his basic patents.
From the early days of pictures representing simple movements, such as
a man sneezing, or a skirt-dance, there has been a gradual evolution, until
now the pictures represent not only actual events in all their palpitating
instantaneity, but highly developed dramas and scenarios enacted in large,
well-equipped glass studios, and the result of infinite pains and expense of
production. These pictures are exhibited in upward of eight thousand places
of amusement in the United States, and are witnessed by millions of people
each year. They constitute a cheap, clean form of amusement for many
persons who cannot spare the money to go to the ordinary theatres, or they
may be exhibited in towns that are too small to support a theatre. More than
this, they offer to the poor man an effective substitute for the saloon.
Probably no invention ever made has afforded more pleasure and
entertainment than the motion picture.
Aside from the development of the motion picture as a spectacle, there
has gone on an evolution in its use for educational purposes of wide range,
which must not be overlooked. In fact, this form of utilization has been
carried further in Europe than in this country as a means of demonstration
in the arts and sciences. One may study animal life, watch a surgical
operation, follow the movement of machinery, take lessons in facial
expression or in calisthenics. It seems a pity that in motion pictures should
at last have been found the only competition that the ancient marionettes
cannot withstand. But aside from the disappearance of those entertaining
puppets, all else is gain in the creation of this new art.

may be exhibited in towns that are too small to support a theatre. More than
this, they offer to the poor man an effective substitute for the saloon.
Probably no invention ever made has afforded more pleasure and
entertainment than the motion picture.
Aside from the development of the motion picture as a spectacle, there
has gone on an evolution in its use for educational purposes of wide range,
which must not be overlooked. In fact, this form of utilization has been
carried further in Europe than in this country as a means of demonstration
in the arts and sciences. One may study animal life, watch a surgical
operation, follow the movement of machinery, take lessons in facial
expression or in calisthenics. It seems a pity that in motion pictures should
at last have been found the only competition that the ancient marionettes
cannot withstand. But aside from the disappearance of those entertaining
puppets, all else is gain in the creation of this new art.

The work at the Edison laboratory in the development of the motion
picture was as usual intense and concentrated, and, as might be expected,
many of the early experiments were quite primitive in their character until
command had been secured of relatively perfect apparatus. The subjects
registered jerkily by the films were crude and amusing, such as of Fred Ott's
sneeze, Carmencita dancing, Italians and their performing bears, fencing,
trapeze stunts, horsemanship, blacksmithing—just simple movements
without any attempt to portray the silent drama. One curious incident of this
early study occurred when "Jim" Corbett was asked to box a few rounds in
front of the camera, with a "dark un" to be selected locally. This was agreed
to, and a celebrated bruiser was brought over from Newark. When this
"sparring partner" came to face Corbett in the imitation ring he was so
paralyzed with terror he could hardly move. It was just after Corbett had
won one of his big battles as a prize-fighter, and the dismay of his opponent
was excusable. The "boys" at the laboratory still laugh consumedly when
they tell about it.
The first motion-picture studio was dubbed by the staff the "Black
Maria." It was an unpretentious oblong wooden structure erected in the
laboratory yard, and had a movable roof in the central part. This roof could
be raised or lowered at will. The building was covered with black roofing
paper, and was also painted black inside. There was no scenery to render
gay this lugubrious environment, but the black interior served as the
common background for the performers, throwing all their actions into high
relief. The whole structure was set on a pivot so that it could be swung
around with the sun; and the movable roof was opened so that the
accentuating sunlight could stream in upon the actor whose gesticulations
were being caught by the camera. These beginnings and crudities are very
remote from the elaborate and expensive paraphernalia and machinery with
which the art is furnished to-day.
At the present time the studios in which motion pictures are taken are
expensive and pretentious affairs. An immense building of glass, with all
the properties and stage-settings of a regular theatre, is required. The Bronx
Park studio of the Edison company cost at least one hundred thousand
dollars, while the well-known house of Pathe Freres in France—one of
Edison's licensees—makes use of no fewer than seven of these glass
theatres. All of the larger producers of pictures in this country and abroad
employ regular stock companies of actors, men and women selected

employ regular stock companies of actors, men and women selected
Page 361
especially for their skill in pantomime, although, as most observers have
perhaps suspected, in the actual taking of the pictures the performers are
required to carry on an animated and prepared dialogue with the same spirit
and animation as on the regular stage. Before setting out on the preparation
of a picture, the book is first written—known in the business as a scenario
—giving a complete statement as to the scenery, drops and background, and
the sequence of events, divided into scenes as in an ordinary play. These are
placed in the hands of a "producer," corresponding to a stage-director,
generally an actor or theatrical man of experience, with a highly developed
dramatic instinct. The various actors are selected, parts are assigned, and the
scene-painters are set to work on the production of the desired scenery.
Before the photographing of a scene, a long series of rehearsals takes place,
the incidents being gone over and over again until the actors are "letter
perfect." So persistent are the producers in the matter of rehearsals and the
refining and elaboration of details, that frequently a picture that may be
actually photographed and reproduced in fifteen minutes, may require two
or three weeks for its production. After the rehearsal of a scene has
advanced sufficiently to suit the critical requirements of the producer, the
camera man is in requisition, and he is consulted as to lighting so as to
produce the required photographic effect. Preferably, of course, sunlight is
used whenever possible, hence the glass studios; but on dark days, and
when night-work is necessary, artificial light of enormous candle-power is
used, either mercury arcs or ordinary arc lights of great size and number.
Under all conditions the light is properly screened and diffused to suit the
critical eye of the camera man. All being in readiness, the actual picture is
taken, the actors going through their rehearsed parts, the producer standing
out of the range of the camera, and with a megaphone to his lips yelling out
his instructions, imprecations, and approval, and the camera man grinding
at the crank of the camera and securing the pictures at the rate of twenty or
more per second, making a faithful and permanent record of every
movement and every change of facial expression. At the end of the scene
the negative is developed in the ordinary way, and is then ready for use in
the printing of the positives for sale. When a further scene in the play takes
place in the same setting, and without regard to its position in the plot, it is
taken up, rehearsed, and photographed in the same way, and afterward all
the scenes are cemented together in the proper sequence, and form the
complete negative. Frequently, therefore, in the production of a motion-

Page 362
picture play, the first and the last scene may be taken successively, the only
thing necessary being, of course, that after all is done the various scenes
should be arranged in their proper order. The frames, having served their
purpose, now go back to the scene-painter for further use. All pictures are
not taken in studios, because when light and weather permit and proper
surroundings can be secured outside, scenes can best be obtained with
natural scenery—city streets, woods, and fields. The great drawback to the
taking of pictures out-of-doors, however, is the inevitable crowd, attracted
by the novelty of the proceedings, which makes the camera man's life a
torment by getting into the field of his instrument. The crowds are patient,
however, and in one Edison picture involving the blowing up of a bridge by
the villain of the piece and the substitution of a pontoon bridge by a
company of engineers just in time to allow the heroine to pass over in her
automobile, more than a thousand people stood around for almost an entire
day waiting for the tedious rehearsals to end and the actual performance to
begin. Frequently large bodies of men are used in pictures, such as troops of
soldiers, and it is an open secret that for weeks during the Boer War
regularly equipped British and Boer armies confronted each other on the
peaceful hills of Orange, New Jersey, ready to enact before the camera the
stirring events told by the cable from the seat of hostilities. These conflicts
were essentially harmless, except in one case during the battle of Spion
Kopje, when "General Cronje," in his efforts to fire a wooden cannon,
inadvertently dropped his fuse into a large glass bottle containing
gunpowder. The effect was certainly most dramatic, and created great
enthusiasm among the many audiences which viewed the completed
production; but the unfortunate general, who is still an employee, was taken
to the hospital, and even now, twelve years afterward, he says with a grin
that whenever he has a moment of leisure he takes the time to pick a few
pieces of glass from his person!
Edison's great contribution to the regular stage was the incandescent
electric lamp, which enabled the production of scenic effects never before
even dreamed of, but which we accept now with so much complacency. Yet
with the motion picture, effects are secured that could not be reproduced to
the slightest extent on the real stage. The villain, overcome by a remorseful
conscience, sees on the wall of the room the very crime which he
committed, with HIMSELF as the principal actor; one of the easy effects of
double exposure. The substantial and ofttimes corpulent ghost or spirit of

the real stage has been succeeded by an intangible wraith, as transparent
and unsubstantial as may be demanded in the best book of fairy tales—
more double exposure. A man emerges from the water with a splash,
ascends feet foremost ten yards or more, makes a graceful curve and lands
on a spring-board, runs down it to the bank, and his clothes fly gently up
from the ground and enclose his person—all unthinkable in real life, but
readily possible by running the motion-picture film backward! The fairy
prince commands the princess to appear, consigns the bad brothers to
instant annihilation, turns the witch into a cat, confers life on inanimate
things; and many more startling and apparently incomprehensible effects
are carried out with actual reality, by stop-work photography. In one case,
when the command for the heroine to come forth is given, the camera is
stopped, the young woman walks to the desired spot, and the camera is
again started; the effect to the eye—not knowing of this little by-play—is as
if she had instantly appeared from space. The other effects are perhaps
obvious, and the field and opportunities are absolutely unlimited. Other
curious effects are secured by taking the pictures at a different speed from
that at which they are exhibited. If, for example, a scene occupying thirty
seconds is reproduced in ten seconds, the movements will be three times as
fast, and vice versa. Many scenes familiar to the reader, showing
automobiles tearing along the road and rounding corners at an apparently
reckless speed, are really pictures of slow and dignified movements
reproduced at a high speed.
Brief reference has been made to motion pictures of educational subjects,
and in this field there are very great opportunities for development. The
study of geography, scenes and incidents in foreign countries, showing the
lives and customs and surroundings of other peoples, is obviously more
entertaining to the child when actively depicted on the screen than when
merely described in words. The lives of great men, the enacting of
important historical events, the reproduction of great works of literature, if
visually presented to the child must necessarily impress his mind with
greater force than if shown by mere words. We predict that the time is not
far distant when, in many of our public schools, two or three hours a week
will be devoted to this rational and effective form of education.
By applying microphotography to motion pictures an additional field is
opened up, one phase of which may be the study of germ life and bacteria,
and unsubstantial as may be demanded in the best book of fairy tales—
more double exposure. A man emerges from the water with a splash,

that in the motion picture, perhaps more than with any other invention,
Edison has created an art that must always make a special appeal to the
mind and emotions of men, and although so far it has not advanced much
beyond the field of amusement, it contains enormous possibilities for
serious development in the future. Let us not think too lightly of the humble

CHAPTER XXII
THE DEVELOPMENT OF THE EDISON STORAGE
BATTERY
IT is more than a hundred years since the elementary principle of the
storage battery or "accumulator" was detected by a Frenchman named
Gautherot; it is just fifty years since another Frenchman, named Plante,
discovered that on taking two thin plates of sheet lead, immersing them in
dilute sulphuric acid, and passing an electric current through the cell, the
combination exhibited the ability to give back part of the original charging
current, owing to the chemical changes and reactions set up. Plante coiled
up his sheets into a very handy cell like a little roll of carpet or pastry; but
the trouble was that the battery took a long time to "form." One sheet
becoming coated with lead peroxide and the other with finely divided or
spongy metallic lead, they would receive current, and then, even after a
long period of inaction, furnish or return an electromotive force of from
1.85 to 2.2 volts. This ability to store up electrical energy produced by
dynamos in hours otherwise idle, whether driven by steam, wind, or water,
was a distinct advance in the art; but the sensational step was taken about
1880, when Faure in France and Brush in America broke away from the
slow and weary process of "forming" the plates, and hit on clever methods
of furnishing them "ready made," so to speak, by dabbing red lead onto
lead-grid plates, just as butter is spread on a slice of home-made bread. This
brought the storage battery at once into use as a practical, manufactured
piece of apparatus; and the world was captivated with the idea. The great
English scientist, Sir William Thomson, went wild with enthusiasm when a
Faure "box of electricity" was brought over from Paris to him in 1881
containing a million foot-pounds of stored energy. His biographer, Dr.
Sylvanus P. Thompson, describes him as lying ill in bed with a wounded
leg, and watching results with an incandescent lamp fastened to his bed
curtain by a safety-pin, and lit up by current from the little Faure cell. Said
Sir William: "It is going to be a most valuable, practical affair—as valuable

Sylvanus P. Thompson, describes him as lying ill in bed with a wounded
leg, and watching results with an incandescent lamp fastened to his bed
curtain by a safety-pin, and lit up by current from the little Faure cell. Said
Sir William: "It is going to be a most valuable, practical affair—as valuable
as water-cisterns to people whether they had or had not systems of water-
Page 366
pipes and water-supply." Indeed, in one outburst of panegyric the shrewd
physicist remarked that he saw in it "a realization of the most ardently and
increasingly felt scientific aspiration of his life—an aspiration which he
hardly dared to expect or to see realized." A little later, however, Sir
William, always cautious and canny, began to discover the inherent defects
of the primitive battery, as to disintegration, inefficiency, costliness, etc.,
and though offered tempting inducements, declined to lend his name to its
financial introduction. Nevertheless, he accepted the principle as valuable,
and put the battery to actual use.
For many years after this episode, the modern lead-lead type of battery
thus brought forward with so great a flourish of trumpets had a hard time of
it. Edison's attitude toward it, even as a useful supplement to his lighting
system, was always one of scepticism, and he remarked contemptuously
that the best storage battery he knew was a ton of coal. The financial
fortunes of the battery, on both sides of the Atlantic, were as varied and as
disastrous as its industrial; but it did at last emerge, and "made good." By
1905, the production of lead-lead storage batteries in the United States
alone had reached a value for the year of nearly $3,000,000, and it has
increased greatly since that time. The storage battery is now regarded as an
important and indispensable adjunct in nearly all modern electric-lighting
and electric-railway systems of any magnitude; and in 1909, in spite of its
weight, it had found adoption in over ten thousand automobiles of the truck,
delivery wagon, pleasure carriage, and runabout types in America.
Edison watched closely all this earlier development for about fifteen
years, not changing his mind as to what he regarded as the incurable defects
of the lead-lead type, but coming gradually to the conclusion that if a
storage battery of some other and better type could be brought forward, it
would fulfil all the early hopes, however extravagant, of such men as
Kelvin (Sir William Thomson), and would become as necessary and as
universal as the incandescent lamp or the electric motor. The beginning of
the present century found him at his point of new departure.
Generally speaking, non-technical and uninitiated persons have a
tendency to regard an invention as being more or less the ultimate result of
some happy inspiration. And, indeed, there is no doubt that such may be the
fact in some instances; but in most cases the inventor has intentionally set
out to accomplish a definite and desired result—mostly through the

fact in some instances; but in most cases the inventor has intentionally set
out to accomplish a definite and desired result—mostly through the
Page 367
application of the known laws of the art in which he happens to be working.
It is rarely, however, that a man will start out deliberately, as Edison did, to
evolve a radically new type of such an intricate device as the storage
battery, with only a meagre clew and a vague starting-point.
In view of the successful outcome of the problem which, in 1900, he
undertook to solve, it will be interesting to review his mental attitude at that
period. It has already been noted at the end of a previous chapter that on
closing the magnetic iron-ore concentrating plant at Edison, New Jersey, he
resolved to work on a new type of storage battery. It was about this time
that, in the course of a conversation with Mr. R. H. Beach, then of the
street-railway department of the General Electric Company, he said:
"Beach, I don't think Nature would be so unkind as to withhold the secret of
a GOOD storage battery if a real earnest hunt for it is made. I'm going to
hunt."
Frequently Edison has been asked what he considers the secret of
achievement. To this query he has invariably replied: "Hard work, based on
hard thinking." The laboratory records bear the fullest witness that he has
consistently followed out this prescription to the utmost. The perfection of
all his great inventions has been signalized by patient, persistent, and
incessant effort which, recognizing nothing short of success, has resulted in
the ultimate accomplishment of his ideas. Optimistic and hopeful to a high
degree, Edison has the happy faculty of beginning the day as open-minded
as a child—yesterday's disappointments and failures discarded and
discounted by the alluring possibilities of to-morrow.
Of all his inventions, it is doubtful whether any one of them has called
forth more original thought, work, perseverance, ingenuity, and
monumental patience than the one we are now dealing with. One of his
associates who has been through the many years of the storage-battery
drudgery with him said: "If Edison's experiments, investigations, and work
on this storage battery were all that he had ever done, I should say that he
was not only a notable inventor, but also a great man. It is almost
impossible to appreciate the enormous difficulties that have been
overcome."
From a beginning which was made practically in the dark, it was not until
he had completed more than ten thousand experiments that he obtained any
positive preliminary results whatever. Through all this vast amount of
It is rarely, however, that a man will start out deliberately, as Edison did, to
evolve a radically new type of such an intricate device as the storage
battery, with only a meagre clew and a vague starting-point.
In view of the successful outcome of the problem which, in 1900, he
undertook to solve, it will be interesting to review his mental attitude at that
period. It has already been noted at the end of a previous chapter that on
closing the magnetic iron-ore concentrating plant at Edison, New Jersey, he
resolved to work on a new type of storage battery. It was about this time
that, in the course of a conversation with Mr. R. H. Beach, then of the
street-railway department of the General Electric Company, he said:
"Beach, I don't think Nature would be so unkind as to withhold the secret of
a GOOD storage battery if a real earnest hunt for it is made. I'm going to
hunt."
Frequently Edison has been asked what he considers the secret of
achievement. To this query he has invariably replied: "Hard work, based on
hard thinking." The laboratory records bear the fullest witness that he has
consistently followed out this prescription to the utmost. The perfection of
all his great inventions has been signalized by patient, persistent, and
incessant effort which, recognizing nothing short of success, has resulted in
the ultimate accomplishment of his ideas. Optimistic and hopeful to a high
degree, Edison has the happy faculty of beginning the day as open-minded
as a child—yesterday's disappointments and failures discarded and
discounted by the alluring possibilities of to-morrow.
Of all his inventions, it is doubtful whether any one of them has called
forth more original thought, work, perseverance, ingenuity, and
monumental patience than the one we are now dealing with. One of his
associates who has been through the many years of the storage-battery
drudgery with him said: "If Edison's experiments, investigations, and work
on this storage battery were all that he had ever done, I should say that he
was not only a notable inventor, but also a great man. It is almost
impossible to appreciate the enormous difficulties that have been
overcome."
From a beginning which was made practically in the dark, it was not until
he had completed more than ten thousand experiments that he obtained any
positive preliminary results whatever. Through all this vast amount of
Page 368
research there had been no previous signs of the electrical action he was
looking for. These experiments had extended over many months of constant
work by day and night, but there was no breakdown of Edison's faith in
ultimate success—no diminution of his sanguine and confident
expectations. The failure of an experiment simply meant to him that he had
found something else that would not work, thus bringing the possible goal a
little nearer by a process of painstaking elimination.
Now, however, after these many months of arduous toil, in which he had
examined and tested practically all the known elements in numerous
chemical combinations, the electric action he sought for had been obtained,
thus affording him the first inkling of the secret that he had industriously
tried to wrest from Nature. It should be borne in mind that from the very
outset Edison had disdained any intention of following in the only tracks
then known by employing lead and sulphuric acid as the components of a
successful storage battery. Impressed with what he considered the serious
inherent defects of batteries made of these materials, and the tremendously
complex nature of the chemical reactions taking place in all types of such
cells, he determined boldly at the start that he would devise a battery
without lead, and one in which an alkaline solution could be used—a form
which would, he firmly believed, be inherently less subject to decay and
dissolution than the standard type, which after many setbacks had finally
won its way to an annual production of many thousands of cells, worth
millions of dollars.
Two or three thousand of the first experiments followed the line of his
well-known primary battery in the attempted employment of copper oxide
as an element in a new type of storage cell; but its use offered no
advantages, and the hunt was continued in other directions and pursued
until Edison satisfied himself by a vast number of experiments that nickel
and iron possessed the desirable qualifications he was in search of.
This immense amount of investigation which had consumed so many
months of time, and which had culminated in the discovery of a series of
reactions between nickel and iron that bore great promise, brought Edison
merely within sight of a strange and hitherto unexplored country. Slowly
but surely the results of the last few thousands of his preliminary
experiments had pointed inevitably to a new and fruitful region ahead. He
had discovered the hidden passage and held the clew which he had so
looking for. These experiments had extended over many months of constant
work by day and night, but there was no breakdown of Edison's faith in
ultimate success—no diminution of his sanguine and confident
expectations. The failure of an experiment simply meant to him that he had

had discovered the hidden passage and held the clew which he had so
Page 369
industriously sought. And now, having outlined a definite path, Edison was
all afire to push ahead vigorously in order that he might enter in and possess
the land.
It is a trite saying that "history repeats itself," and certainly no axiom
carries more truth than this when applied to the history of each of Edison's
important inventions. The development of the storage battery has been no
exception; indeed, far from otherwise, for in the ten years that have elapsed
since the time he set himself and his mechanics, chemists, machinists, and
experimenters at work to develop a practical commercial cell, the old story
of incessant and persistent efforts so manifest in the working out of other
inventions was fully repeated.
Very soon after he had decided upon the use of nickel and iron as the
elemental metals for his storage battery, Edison established a chemical plant
at Silver Lake, New Jersey, a few miles from the Orange laboratory, on land
purchased some time previously. This place was the scene of the further
experiments to develop the various chemical forms of nickel and iron, and
to determine by tests what would be best adapted for use in cells
manufactured on a commercial scale. With a little handful of selected
experimenters gathered about him, Edison settled down to one of his
characteristic struggles for supremacy. To some extent it was a revival of
the old Menlo Park days (or, rather, nights). Some of these who had worked
on the preliminary experiments, with the addition of a few new-comers,
toiled together regardless of passing time and often under most
discouraging circumstances, but with that remarkable esprit de corps that
has ever marked Edison's relations with his co-workers, and that has
contributed so largely to the successful carrying out of his ideas.
The group that took part in these early years of Edison's arduous labors
included his old-time assistant, Fred Ott, together with his chemist, J. W.
Aylsworth, as well as E. J. Ross, Jr., W. E. Holland, and Ralph Arbogast,
and a little later W. G. Bee, all of whom have grown up with the battery and
still devote their energies to its commercial development. One of these
workers, relating the strenuous experiences of these few years, says: "It was
hard work and long hours, but still there were some things that made life
pleasant. One of them was the supper-hour we enjoyed when we worked
nights. Mr. Edison would have supper sent in about midnight, and we all sat
down together, including himself. Work was forgotten for the time, and all
all afire to push ahead vigorously in order that he might enter in and possess
the land.

Page 370
hands were ready for fun. I have very pleasant recollections of Mr. Edison
at these times. He would always relax and help to make a good time, and on
some occasions I have seen him fairly overflow with animal spirits, just like
a boy let out from school. After the supper-hour was over, however, he
again became the serious, energetic inventor, deeply immersed in the work
at hand.
"He was very fond of telling and hearing stories, and always appreciated
a joke. I remember one that he liked to get off on us once in a while. Our
lighting plant was in duplicate, and about 12.30 or 1 o'clock in the morning,
at the close of the supper-hour, a change would be made from one plant to
the other, involving the gradual extinction of the electric lights and their
slowly coming up to candle-power again, the whole change requiring
probably about thirty seconds. Sometimes, as this was taking place, Edison
would fold his hands, compose himself as if he were in sound sleep, and
when the lights were full again would apparently wake up, with the remark,
'Well, boys, we've had a fine rest; now let's pitch into work again.'"
Another interesting and amusing reminiscence of this period of activity
has been gathered from another of the family of experimenters:
"Sometimes, when Mr. Edison had been working long hours, he would want
to have a short sleep. It was one of the funniest things I ever witnessed to
see him crawl into an ordinary roll-top desk and curl up and take a nap. If
there was a sight that was still more funny, it was to see him turn over on
his other side, all the time remaining in the desk. He would use several
volumes of Watts's Dictionary of Chemistry for a pillow, and we fellows
used to say that he absorbed the contents during his sleep, judging from the
flow of new ideas he had on waking."
Such incidents as these serve merely to illustrate the lighter moments that
stand out in relief against the more sombre background of the strenuous
years, for, of all the absorbingly busy periods of Edison's inventive life, the
first five years of the storage-battery era was one of the very busiest of them
all. It was not that there remained any basic principle to be discovered or
simplified, for that had already been done; but it was in the effort to carry
these principles into practice that there arose the numerous difficulties that
at times seemed insurmountable. But, according to another co-worker,
"Edison seemed pleased when he used to run up against a serious difficulty.
It would seem to stiffen his backbone and make him more prolific of new
at these times. He would always relax and help to make a good time, and on
some occasions I have seen him fairly overflow with animal spirits, just like

ideas. For a time I thought I was foolish to imagine such a thing, but I could
never get away from the impression that he really appeared happy when he
ran up against a serious snag. That was in my green days, and I soon
learned that the failure of an experiment never discourages him unless it is
by reason of the carelessness of the man making it. Then Edison gets
disgusted. If it fails on its merits, he doesn't worry or fret about it, but, on
the contrary, regards it as a useful fact learned; remains cheerful and tries
something else. I have known him to reverse an unsuccessful experiment
and come out all right."
To follow Edison's trail in detail through the innumerable twists and turns
of his experimentation and research on the storage battery, during the past
ten years, would not be in keeping with the scope of this narrative, nor
would it serve any useful purpose. Besides, such details would fill a big
volume. The narrative, however, would not be complete without some
mention of the general outline of his work, and reference may be made
briefly to a few of the chief items. And lest the reader think that the word
"innumerable" may have been carelessly or hastily used above, we would
quote the reply of one of the laboratory assistants when asked how many
experiments had been made on the Edison storage battery since the year
1900: "Goodness only knows! We used to number our experiments
consecutively from 1 to 10,000, and when we got up to 10,000 we turned
back to 1 and ran up to 10,000 again, and so on. We ran through several
series—I don't know how many, and have lost track of them now, but it was
not far from fifty thousand."
From the very first, Edison's broad idea of his storage battery was to
make perforated metallic containers having the active materials packed
therein; nickel hydrate for the positive and iron oxide for the negative plate.
This plan has been adhered to throughout, and has found its consummation
in the present form of the completed commercial cell, but in the middle
ground which stands between the early crude beginnings and the perfected
type of to-day there lies a world of original thought, patient plodding, and
achievement.
The first necessity was naturally to obtain the best and purest compounds
for active materials. Edison found that comparatively little was known by
manufacturing chemists about nickel and iron oxides of the high grade and
purity he required. Hence it became necessary for him to establish his own

for active materials. Edison found that comparatively little was known by
manufacturing chemists about nickel and iron oxides of the high grade and
purity he required. Hence it became necessary for him to establish his own
Page 372
chemical works and put them in charge of men specially trained by himself,
with whom he worked. This was the plant at Silver Lake, above referred to.
Here, for several years, there was ceaseless activity in the preparation of
these chemical compounds by every imaginable process and subsequent
testing. Edison's chief chemist says: "We left no stone unturned to find a
way of making those chemicals so that they would give the highest results.
We carried on the experiments with the two chemicals together. Sometimes
the nickel would be ahead in the tests, and then again it would fall behind.
To stimulate us to greater improvement, Edison hung up a card which
showed the results of tests in milliampere-hours given by the experimental
elements as we tried them with the various grades of nickel and iron we had
made. This stirred up a great deal of ambition among the boys to push the
figures up. Some of our earliest tests showed around 300, but as we
improved the material, they gradually crept up to over 500. Just about that
time Edison made a trip to Canada, and when he came back we had made
such good progress that the figures had crept up to about 1000. I well
remember how greatly he was pleased."
In speaking of the development of the negative element of the battery,
Mr. Aylsworth said: "In like manner the iron element had to be developed
and improved; and finally the iron, which had generally enjoyed superiority
in capacity over its companion, the nickel element, had to go in training in
order to retain its lead, which was imperative, in order to produce a uniform
and constant voltage curve. In talking with me one day about the difficulties
under which we were working and contrasting them with the phonograph
experimentation, Edison said: 'In phonographic work we can use our ears
and our eyes, aided with powerful microscopes; but in the battery our
difficulties cannot be seen or heard, but must be observed by our mind's
eye!' And by reason of the employment of such vision in the past, Edison is
now able to see quite clearly through the forest of difficulties after
eliminating them one by one."
The size and shape of the containing pockets in the battery plates or
elements and the degree of their perforation were matters that received
many years of close study and experiment; indeed, there is still to-day
constant work expended on their perfection, although their present general
form was decided upon several years ago. The mechanical construction of
the battery, as a whole, in its present form, compels instant admiration on
account of its beauty and completeness. Mr. Edison has spared neither
with whom he worked. This was the plant at Silver Lake, above referred to.

Page 373
thought, ingenuity, labor, nor money in the effort to make it the most
complete and efficient storage cell obtainable, and the results show that his
skill, judgment, and foresight have lost nothing of the power that laid the
foundation of, and built up, other great arts at each earlier stage of his
career.
Among the complex and numerous problems that presented themselves
in the evolution of the battery was the one concerning the internal
conductivity of the positive unit. The nickel hydrate was a poor electrical
conductor, and although a metallic nickel pocket might be filled with it,
there would not be the desired electrical action unless a conducting
substance were mixed with it, and so incorporated and packed that there
would be good electrical contact throughout. This proved to be a most
knotty and intricate puzzle—tricky and evasive—always leading on and
promising something, and at the last slipping away leaving the work
undone. Edison's remarkable patience and persistence in dealing with this
trying problem and in finally solving it successfully won for him more than
ordinary admiration from his associates. One of them, in speaking of the
seemingly interminable experiments to overcome this trouble, said: "I guess
that question of conductivity of the positive pocket brought lots of gray
hairs to his head. I never dreamed a man could have such patience and
perseverance. Any other man than Edison would have given the whole thing
up a thousand times, but not he! Things looked awfully blue to the whole
bunch of us many a time, but he was always hopeful. I remember one time
things looked so dark to me that I had just about made up my mind to throw
up my job, but some good turn came just then and I didn't. Now I'm glad I
held on, for we've got a great future."
The difficulty of obtaining good electrical contact in the positive element
was indeed Edison's chief trouble for many years. After a great amount of
work and experimentation he decided upon a certain form of graphite,
which seemed to be suitable for the purpose, and then proceeded to the
commercial manufacture of the battery at a special factory in Glen Ridge,
New Jersey, installed for the purpose. There was no lack of buyers, but, on
the contrary, the factory was unable to turn out batteries enough. The
newspapers had previously published articles showing the unusual capacity
and performance of the battery, and public interest had thus been greatly
awakened.

and performance of the battery, and public interest had thus been greatly

Page 374
Notwithstanding the establishment of a regular routine of manufacture
and sale, Edison did not cease to experiment for improvement. Although the
graphite apparently did the work desired of it, he was not altogether
satisfied with its performance and made extended trials of other substances,
but at that time found nothing that on the whole served the purpose better.
Continuous tests of the commercial cells were carried on at the laboratory,
as well as more practical and heavy tests in automobiles, which were
constantly kept running around the adjoining country over all kinds of
roads. All these tests were very closely watched by Edison, who demanded
rigorously that the various trials of the battery should be carried on with all
strenuousness so as to get the utmost results and develop any possible
weakness. So insistent was he on this, that if any automobile should run
several days without bursting a tire or breaking some part of the machine,
he would accuse the chauffeur of picking out easy roads.
After these tests had been going on for some time, and some thousands of
cells had been sold and were giving satisfactory results to the purchasers,
the test sheets and experience gathered from various sources pointed to the
fact that occasionally a cell here and there would show up as being short in
capacity. Inasmuch as the factory processes were very exact and carefully
guarded, and every cell was made as uniform as human skill and care could
provide, there thus arose a serious problem. Edison concentrated his powers
on the investigation of this trouble, and found that the chief cause lay in the
graphite. Some other minor matters also attracted his attention. What to do,
was the important question that confronted him. To shut down the factory
meant great loss and apparent failure. He realized this fully, but he also
knew that to go on would simply be to increase the number of defective
batteries in circulation, which would ultimately result in a permanent
closure and real failure. Hence he took the course which one would expect
of Edison's common sense and directness of action. He was not satisfied
that the battery was a complete success, so he shut down and went to
experimenting once more.
"And then," says one of the laboratory men, "we started on another series
of record-breaking experiments that lasted over five years. I might almost
say heart-breaking, too, for of all the elusive, disappointing things one ever
hunted for that was the worst. But secrets have to be long-winded and roost
high if they want to get away when the 'Old Man' goes hunting for them. He
doesn't get mad when he misses them, but just keeps on smiling and firing,

strenuousness so as to get the utmost results and develop any possible
weakness. So insistent was he on this, that if any automobile should run
several days without bursting a tire or breaking some part of the machine,
he would accuse the chauffeur of picking out easy roads.
After these tests had been going on for some time, and some thousands of
cells had been sold and were giving satisfactory results to the purchasers,
the test sheets and experience gathered from various sources pointed to the
fact that occasionally a cell here and there would show up as being short in
capacity. Inasmuch as the factory processes were very exact and carefully
guarded, and every cell was made as uniform as human skill and care could
provide, there thus arose a serious problem. Edison concentrated his powers
on the investigation of this trouble, and found that the chief cause lay in the
graphite. Some other minor matters also attracted his attention. What to do,
was the important question that confronted him. To shut down the factory
meant great loss and apparent failure. He realized this fully, but he also
knew that to go on would simply be to increase the number of defective
batteries in circulation, which would ultimately result in a permanent
closure and real failure. Hence he took the course which one would expect
of Edison's common sense and directness of action. He was not satisfied
that the battery was a complete success, so he shut down and went to
experimenting once more.
"And then," says one of the laboratory men, "we started on another series
of record-breaking experiments that lasted over five years. I might almost
say heart-breaking, too, for of all the elusive, disappointing things one ever
hunted for that was the worst. But secrets have to be long-winded and roost
high if they want to get away when the 'Old Man' goes hunting for them. He
doesn't get mad when he misses them, but just keeps on smiling and firing,
Page 375
and usually brings them into camp. That's what he did on the battery, for
after a whole lot of work he perfected the nickel-flake idea and process,
besides making the great improvement of using tubes instead of flat pockets
for the positive. He also added a minor improvement here and there, and
now we have a finer battery than we ever expected."
In the interim, while the experimentation of these last five years was in
progress, many customers who had purchased batteries of the original type
came knocking at the door with orders in their hands for additional outfits
wherewith to equip more wagons and trucks. Edison expressed his regrets,
but said he was not satisfied with the old cells and was engaged in
improving them. To which the customers replied that THEY were entirely
satisfied and ready and willing to pay for more batteries of the same kind;
but Edison could not be moved from his determination, although
considerable pressure was at times brought to bear to sway his decision.
Experiment was continued beyond the point of peradventure, and after
some new machinery had been built, the manufacture of the new type of
cell was begun in the early summer of 1909, and at the present writing is
being extended as fast as the necessary additional machinery can be made.
The product is shipped out as soon as it is completed.
The nickel flake, which is Edison's ingenious solution of the conductivity
problem, is of itself a most interesting product, intensely practical in its
application and fascinating in its manufacture. The flake of nickel is
obtained by electroplating upon a metallic cylinder alternate layers of
copper and nickel, one hundred of each, after which the combined sheet is
stripped from the cylinder. So thin are the layers that this sheet is only about
the thickness of a visiting-card, and yet it is composed of two hundred
layers of metal. The sheet is cut into tiny squares, each about one-sixteenth
of an inch, and these squares are put into a bath where the copper is
dissolved out. This releases the layers of nickel, so that each of these small
squares becomes one hundred tiny sheets, or flakes, of pure metallic nickel,
so thin that when they are dried they will float in the air, like thistle-down.
In their application to the manufacture of batteries, the flakes are used
through the medium of a special machine, so arranged that small charges of
nickel hydrate and nickel flake are alternately fed into the pockets intended
for positives, and tamped down with a pressure equal to about four tons per
after a whole lot of work he perfected the nickel-flake idea and process,

square inch. This insures complete and perfect contact and consequent
electrical conductivity throughout the entire unit.
The development of the nickel flake contains in itself a history of patient
investigation, labor, and achievement, but we have not space for it, nor for
tracing the great work that has been done in developing and perfecting the
numerous other parts and adjuncts of this remarkable battery. Suffice it to
say that when Edison went boldly out into new territory, after something
entirely unknown, he was quite prepared for hard work and exploration. He
encountered both in unstinted measure, but kept on going forward until,
after long travel, he had found all that he expected and accomplished
something more beside. Nature DID respond to his whole-hearted appeal,
and, by the time the hunt was ended, revealed a good storage battery of
entirely new type. Edison not only recognized and took advantage of the
principles he had discovered, but in adapting them for commercial use
developed most ingenious processes and mechanical appliances for carrying
his discoveries into practical effect. Indeed, it may be said that the invention
of an enormous variety of new machines and mechanical appliances
rendered necessary by each change during the various stages of
development of the battery, from first to last, stands as a lasting tribute to
the range and versatility of his powers.
It is not within the scope of this narrative to enter into any description of
the relative merits of the Edison storage battery, that being the province of a
commercial catalogue. It does, however, seem entirely allowable to say that
while at the present writing the tests that have been made extend over a few
years only, their results and the intrinsic value of this characteristic Edison
invention are of such a substantial nature as to point to the inevitable
growth of another great industry arising from its manufacture, and to its
wide-spread application to many uses.
The principal use that Edison has had in mind for his battery is
transportation of freight and passengers by truck, automobile, and street-car.
The greatly increased capacity in proportion to weight of the Edison cell
makes it particularly adaptable for this class of work on account of the
much greater radius of travel that is possible by its use. The latter point of
advantage is the one that appeals most to the automobilist, as he is thus
enabled to travel, it is asserted, more than three times farther than ever
before on a single charge of the battery.

Edison believes that there are important advantages possible in the
employment of his storage battery for street-car propulsion. Under the
present system of operation, a plant furnishing the electric power for street
railways must be large enough to supply current for the maximum load
during "rush hours," although much of the machinery may be lying idle and
unproductive in the hours of minimum load. By the use of storage-battery
cars, this immense and uneconomical maximum investment in plant can be
cut down to proportions of true commercial economy, as the charging of the
batteries can be conducted at a uniform rate with a reasonable expenditure
for generating machinery. Not only this, but each car becomes an
independently moving unit, not subject to delay by reason of a general
breakdown of the power plant or of the line. In addition to these advantages,
the streets would be freed from their burden of trolley wires or conduits. To
put his ideas into practice, Edison built a short railway line at the Orange
works in the winter of 1909-10, and, in co-operation with Mr. R. H. Beach,
constructed a special type of street-car, and equipped it with motor, storage
battery, and other necessary operating devices. This car was subsequently
put upon the street-car lines in New York City, and demonstrated its
efficiency so completely that it was purchased by one of the street-car
companies, which has since ordered additional cars for its lines. The
demonstration of this initial car has been watched with interest by many
railroad officials, and its performance has been of so successful a nature
that at the present writing (the summer of 1910) it has been necessary to
organize and equip a preliminary factory in which to construct many other
cars of a similar type that have been ordered by other street-railway
companies. This enterprise will be conducted by a corporation which has
been specially organized for the purpose. Thus, there has been initiated the
development of a new and important industry whose possible ultimate
proportions are beyond the range of present calculation. Extensive as this
industry may become, however, Edison is firmly convinced that the greatest
field for his storage battery lies in its adaptation to commercial trucking and
hauling, and to pleasure vehicles, in comparison with which the street-car
business even with its great possibilities—will not amount to more than 1
per cent.
Edison has pithily summed up his work and his views in an article on
"The To-Morrows of Electricity and Invention" in Popular Electricity for
June, 1910, in which he says: "For years past I have been trying to perfect a

storage battery, and have now rendered it entirely suitable to automobile
and other work. There is absolutely no reason why horses should be

and the horse is still more undesirable. A higher public ideal of health and
cleanliness is working toward such banishment very swiftly; and then we
shall have decent streets, instead of stables made out of strips of
cobblestones bordered by sidewalks. The worst use of money is to make a
fine thoroughfare, and then turn it over to horses. Besides that, the change
will put the humane societies out of business. Many people now charge
their own batteries because of lack of facilities; but I believe central stations
will find in this work very soon the largest part of their load. The New York

CHAPTER XXIII
MISCELLANEOUS INVENTIONS
IT has been the endeavor in this narrative to group Edison's inventions
and patents so that his work in the different fields can be studied
independently and separately. The history of his career has therefore fallen
naturally into a series of chapters, each aiming to describe some particular
development or art; and, in a way, the plan has been helpful to the writers
while probably useful to the readers. It happens, however, that the process
has left a vast mass of discovery and invention wholly untouched, and
relegates to a concluding brief chapter some of the most interesting
episodes of a fruitful life. Any one who will turn to the list of Edison
patents at the end of the book will find a large number of things of which
not even casual mention has been made, but which at the time occupied no
small amount of the inventor's time and attention, and many of which are
now part and parcel of modern civilization. Edison has, indeed, touched
nothing that he did not in some way improve. As Thoreau said: "The laws
of the Universe are not indifferent, but are forever on the side of the most
sensitive," and there never was any one more sensitive to the defects of
every art and appliance, nor any one more active in applying the law of
evolution. It is perhaps this many-sidedness of Edison that has impressed
the multitude, and that in the "popular vote" taken a couple of years ago by
the New York Herald placed his name at the head of the list of ten greatest
living Americans. It is curious and pertinent to note that a similar plebiscite
taken by a technical journal among its expert readers had exactly the same
result. Evidently the public does not agree with the opinion expressed by
the eccentric artist Blake in his "Marriage of Heaven and Hell," when he
said: "Improvement makes strange roads; but the crooked roads without
improvements are roads of Genius."
The product of Edison's brain may be divided into three classes. The first
embraces such arts and industries, or such apparatus, as have already been
treated. The second includes devices like the tasimeter, phonomotor,
odoroscope, etc., and others now to be noted. The third embraces a number

The product of Edison's brain may be divided into three classes. The first
embraces such arts and industries, or such apparatus, as have already been
treated. The second includes devices like the tasimeter, phonomotor,
odoroscope, etc., and others now to be noted. The third embraces a number
Page 380
of projected inventions, partially completed investigations, inventions in
use but not patented, and a great many caveats filed in the Patent Office at
various times during the last forty years for the purpose of protecting his
ideas pending their contemplated realization in practice. These caveats
served their purpose thoroughly in many instances, but there have remained
a great variety of projects upon which no definite action was ever taken.
One ought to add the contents of an unfinished piece of extraordinary
fiction based wholly on new inventions and devices utterly unknown to
mankind. Some day the novel may be finished, but Edison has no
inclination to go back to it, and says he cannot understand how any man is
able to make a speech or write a book, for he simply can't do it.
After what has been said in previous chapters, it will not seem so strange
that Edison should have hundreds of dormant inventions on his hands.
There are human limitations even for such a tireless worker as he is. While
the preparation of data for this chapter was going on, one of the writers in
discussing with him the vast array of unexploited things said: "Don't you
feel a sense of regret in being obliged to leave so many things
uncompleted?" To which he replied: "What's the use? One lifetime is too
short, and I am busy every day improving essential parts of my established
industries." It must suffice to speak briefly of a few leading inventions that
have been worked out, and to dismiss with scant mention all the rest, taking
just a few items, as typical and suggestive, especially when Edison can
himself be quoted as to them. Incidentally it may be noted that things, not
words, are referred to; for Edison, in addition to inventing the apparatus,
has often had to coin the word to describe it. A large number of the words
and phrases in modern electrical parlance owe their origin to him. Even the
"call-word" of the telephone, "Hello!" sent tingling over the wire a few
million times daily was taken from Menlo Park by men installing
telephones in different parts of the world, men who had just learned it at the
laboratory, and thus made it a universal sesame for telephonic conversation.
It is hard to determine where to begin with Edison's miscellaneous
inventions, but perhaps telegraphy has the "right of line," and Edison's work
in that field puts him abreast of the latest wireless developments that fill the
world with wonder. "I perfected a system of train telegraphy between
stations and trains in motion whereby messages could be sent from the
moving train to the central office; and this was the forerunner of wireless
telegraphy. This system was used for a number of years on the Lehigh
use but not patented, and a great many caveats filed in the Patent Office at

telegraphy. This system was used for a number of years on the Lehigh
Page 381
Valley Railroad on their construction trains. The electric wave passed from
a piece of metal on top of the car across the air to the telegraph wires; and
then proceeded to the despatcher's office. In my first experiments with this
system I tried it on the Staten Island Railroad, and employed an operator
named King to do the experimenting. He reported results every day, and
received instructions by mail; but for some reason he could send messages
all right when the train went in one direction, but could not make it go in
the contrary direction. I made suggestions of every kind to get around this
phenomenon. Finally I telegraphed King to find out if he had any
suggestions himself; and I received a reply that the only way he could
propose to get around the difficulty was to put the island on a pivot so it
could be turned around! I found the trouble finally, and the practical
introduction on the Lehigh Valley road was the result. The system was sold
to a very wealthy man, and he would never sell any rights or answer letters.
He became a spiritualist subsequently, which probably explains it." It is
interesting to note that Edison became greatly interested in the later
developments by Marconi, and is an admiring friend and adviser of that
well-known inventor.
The earlier experiments with wireless telegraphy at Menlo Park were
made at a time when Edison was greatly occupied with his electric-light
interests, and it was not until the beginning of 1886 that he was able to
spare the time to make a public demonstration of the system as applied to
moving trains. Ezra T. Gilliland, of Boston, had become associated with
him in his experiments, and they took out several joint patents subsequently.
The first practical use of the system took place on a thirteen-mile stretch of
the Staten Island Railroad with the results mentioned by Edison above.
A little later, Edison and Gilliland joined forces with Lucius J. Phelps,
another investigator, who had been experimenting along the same lines and
had taken out several patents. The various interests were combined in a
corporation under whose auspices the system was installed on the Lehigh
Valley Railroad, where it was used for several years. The official
demonstration trip on this road took place on October 6, 1887, on a six-car
train running to Easton, Pennsylvania, a distance of fifty-four miles. A great

[Footnote 17: Broadly described in outline, the system
consisted of an induction circuit obtained by laying strips
of tin along the top or roof of a railway car, and the
installation of a special telegraph line running parallel
with the track and strung on poles of only medium height.
The train and also each signalling station were equipped
with regulation telegraphic apparatus, such as battery, key,
relay, and sounder, together with induction-coil and
condenser. In addition, there was a transmitting device in
the shape of a musical reed, or buzzer. In practice, this
buzzer was continuously operated at high speed by a battery.
Its vibrations were broken by means of a key into long and
short periods, representing Morse characters, which were
transmitted inductively from the train circuit to the pole
line, or vice versa, and received by the operator at the
other end through a high-resistance telephone receiver
inserted in the secondary circuit of the induction-coil.]
Although the space between the cars and the pole line was probably not
more than about fifty feet, it is interesting to note that in Edison's early
experiments at Menlo Park he succeeded in transmitting messages through
the air at a distance of 580 feet. Speaking of this and of his other
experiments with induction telegraphy by means of kites, communicating
from one to the other and thus from the kites to instruments on the earth,
Edison said recently: "We only transmitted about two and one-half miles
through the kites. What has always puzzled me since is that I did not think
of using the results of my experiments on 'etheric force' that I made in 1875.
I have never been able to understand how I came to overlook them. If I had
made use of my own work I should have had long-distance wireless
telegraphy."
In one of the appendices to this book is given a brief technical account of
Edison's investigations of the phenomena which lie at the root of modern
wireless or "space" telegraphy, and the attention of the reader is directed
particularly to the description and quotations there from the famous note-
books of Edison's experiments in regard to what he called "etheric force." It
will be seen that as early as 1875 Edison detected and studied certain
phenomena—i.e., the production of electrical effects in non-closed circuits,
which for a time made him think he was on the trail of a new force, as there
was no plausible explanation for them by the then known laws of electricity
and magnetism. Later came the magnificent work of Hertz identifying the
phenomena as "electromagnetic waves" in the ether, and developing a new
world of theory and science based upon them and their production by
disruptive discharges.
consisted of an induction circuit obtained by laying strips
of tin along the top or roof of a railway car, and the
installation of a special telegraph line running parallel
with the track and strung on poles of only medium height.
The train and also each signalling station were equipped
with regulation telegraphic apparatus, such as battery, key,
relay, and sounder, together with induction-coil and
condenser. In addition, there was a transmitting device in
the shape of a musical reed, or buzzer. In practice, this
buzzer was continuously operated at high speed by a battery.
Its vibrations were broken by means of a key into long and
short periods, representing Morse characters, which were
transmitted inductively from the train circuit to the pole
line, or vice versa, and received by the operator at the
other end through a high-resistance telephone receiver
inserted in the secondary circuit of the induction-coil.]
Although the space between the cars and the pole line was probably not
more than about fifty feet, it is interesting to note that in Edison's early
experiments at Menlo Park he succeeded in transmitting messages through
the air at a distance of 580 feet. Speaking of this and of his other
experiments with induction telegraphy by means of kites, communicating
from one to the other and thus from the kites to instruments on the earth,
Edison said recently: "We only transmitted about two and one-half miles
through the kites. What has always puzzled me since is that I did not think
of using the results of my experiments on 'etheric force' that I made in 1875.
I have never been able to understand how I came to overlook them. If I had
made use of my own work I should have had long-distance wireless
telegraphy."

Edison's assertions were treated with scepticism by the scientific world,
which was not then ready for the discovery and not sufficiently furnished
with corroborative data. It is singular, to say the least, to note how Edison's
experiments paralleled and proved in advance those that came later; and
even his apparatus such as the "dark box" for making the tiny sparks visible
(as the waves impinged on the receiver) bears close analogy with similar
apparatus employed by Hertz. Indeed, as Edison sent the dark-box
apparatus to the Paris Exposition in 1881, and let Batchelor repeat there the
puzzling experiments, it seems by no means unlikely that, either directly or
on the report of some friend, Hertz may thus have received from Edison a
most valuable suggestion, the inventor aiding the physicist in opening up a
wonderful new realm. In this connection, indeed, it is very interesting to
quote two great authorities. In May, 1889, at a meeting of the Institution of
Electrical Engineers in London, Dr. (now Sir) Oliver Lodge remarked in a
discussion on a paper of his own on lightning conductors, embracing the
Hertzian waves in its treatment: "Many of the effects I have shown—sparks
in unsuspected places and other things—have been observed before. Henry
observed things of the kind and Edison noticed some curious phenomena,
and said it was not electricity but 'etheric force' that caused these sparks;
and the matter was rather pooh-poohed. It was a small part of THIS VERY
THING; only the time was not ripe; theoretical knowledge was not ready
for it." Again in his "Signalling without Wires," in giving the history of the
coherer principle, Lodge remarks: "Sparks identical in all respects with
those discovered by Hertz had been seen in recent times both by Edison and
by Sylvanus Thompson, being styled 'etheric force' by the former; but their
theoretic significance had not been perceived, and they were somewhat
sceptically regarded." During the same discussion in London, in 1889, Sir
William Thomson (Lord Kelvin), after citing some experiments by Faraday
with his insulated cage at the Royal Institution, said: "His (Faraday's)
attention was not directed to look for Hertz sparks, or probably he might
have found them in the interior. Edison seems to have noticed something of
the kind in what he called 'etheric force.' His name 'etheric' may thirteen
years ago have seemed to many people absurd. But now we are all
beginning to call these inductive phenomena 'etheric.'" With which
testimony from the great Kelvin as to his priority in determining the vital
fact, and with the evidence that as early as 1875 he built apparatus that
demonstrated the fact, Edison is probably quite content.

It should perhaps be noted at this point that a curious effect observed at
the laboratory was shown in connection with Edison lamps at the
Philadelphia Exhibition of 1884. It became known in scientific parlance as
the "Edison effect," showing a curious current condition or discharge in the
vacuum of the bulb. It has since been employed by Fleming in England and
De Forest in this country, and others, as the basis for wireless-telegraph
apparatus. It is in reality a minute rectifier of alternating current, and
analogous to those which have since been made on a large scale.
When Roentgen came forward with his discovery of the new "X"-ray in
1895, Edison was ready for it, and took up experimentation with it on a
large scale; some of his work being recorded in an article in the Century
Magazine of May, 1896, where a great deal of data may be found. Edison
says with regard to this work: "When the X-ray came up, I made the first
fluoroscope, using tungstate of calcium. I also found that this tungstate
could be put into a vacuum chamber of glass and fused to the inner walls of
the chamber; and if the X-ray electrodes were let into the glass chamber and
a proper vacuum was attained, you could get a fluorescent lamp of several
candle-power. I started in to make a number of these lamps, but I soon
found that the X-ray had affected poisonously my assistant, Mr. Dally, so
that his hair came out and his flesh commenced to ulcerate. I then
concluded it would not do, and that it would not be a very popular kind of
light; so I dropped it.
"At the time I selected tungstate of calcium because it was so fluorescent,
I set four men to making all kinds of chemical combinations, and thus
collected upward of 8000 different crystals of various chemical
combinations, discovering several hundred different substances which
would fluoresce to the X-ray. So far little had come of X-ray work, but it
added another letter to the scientific alphabet. I don't know any thing about
radium, and I have lots of company." The Electrical Engineer of June 3,
1896, contains a photograph of Mr. Edison taken by the light of one of his
fluorescent lamps. The same journal in its issue of April 1, 1896, shows an
Edison fluoroscope in use by an observer, in the now familiar and universal
form somewhat like a stereoscope. This apparatus as invented by Edison
consists of a flaring box, curved at one end to fit closely over the forehead
and eyes, while the other end of the box is closed by a paste-board cover.
On the inside of this is spread a layer of tungstate of calcium. By placing

the fluorescent screen, the "shadow" is formed on the screen and can be
observed at leisure. The apparatus has proved invaluable in surgery and has
become an accepted part of the equipment of modern surgery. In 1896, at
the Electrical Exhibition in the Grand Central Palace, New York City, given
under the auspices of the National Electric Light Association, thousands and
thousands of persons with the use of this apparatus in Edison's personal
exhibit were enabled to see their own bones; and the resultant public
sensation was great. Mr. Mallory tells a characteristic story of Edison's own
share in the memorable exhibit: "The exhibit was announced for opening on
Monday. On the preceding Friday all the apparatus, which included a large
induction-coil, was shipped from Orange to New York, and on Saturday
afternoon Edison, accompanied by Fred Ott, one of his assistants, and
myself, went over to install it so as to have it ready for Monday morning.
Had everything been normal, a few hours would have sufficed for
completion of the work, but on coming to test the big coil, it was found to
be absolutely out of commission, having been so seriously injured as to
necessitate its entire rewinding. It being summer-time, all the machine
shops were closed until Monday morning, and there were several miles of
wire to be wound on the coil. Edison would not consider a postponement of
the exhibition, so there was nothing to do but go to work and wind it by
hand. We managed to find a lathe, but there was no power; so each of us,
including Edison, took turns revolving the lathe by pulling on the belt,
while the other two attended to the winding of the wire. We worked
continuously all through that Saturday night and all day Sunday until
evening, when we finished the job. I don't remember ever being conscious
of more muscles in my life. I guess Edison was tired also, but he took it
very philosophically." This was apparently the first public demonstration of
the X-ray to the American public.
Edison's ore-separation work has been already fully described, but the
story would hardly be complete without a reference to similar work in gold
extraction, dating back to the Menlo Park days: "I got up a method," says
Edison, "of separating placer gold by a dry process, in which I could work
economically ore as lean as five cents of gold to the cubic yard. I had
several car-loads of different placer sands sent to me and proved I could do
it. Some parties hearing I had succeeded in doing such a thing went to work
and got hold of what was known as the Ortiz mine grant, twelve miles from
Santa Fe, New Mexico. This mine, according to the reports of several
observed at leisure. The apparatus has proved invaluable in surgery and has

and got hold of what was known as the Ortiz mine grant, twelve miles from
Santa Fe, New Mexico. This mine, according to the reports of several
Page 386
mining engineers made in the last forty years, was considered one of the
richest placer deposits in the United States, and various schemes had been
put forward to bring water from the mountains forty miles away to work
those immense beds. The reports stated that the Mexicans had been panning
gold for a hundred years out of these deposits.
"These parties now made arrangements with the stockholders or owners
of the grant, and with me, to work the deposits by my process. As I had had
some previous experience with the statements of mining men, I concluded I
would just send down a small plant and prospect the field before putting up
a large one. This I did, and I sent two of my assistants, whom I could trust,
down to this place to erect the plant; and started to sink shafts fifty feet deep
all over the area. We soon learned that the rich gravel, instead of being
spread over an area of three by seven miles, and rich from the grass roots
down, was spread over a space of about twenty-five acres, and that even
this did not average more than ten cents to the cubic yard. The whole placer
would not give more than one and one-quarter cents per cubic yard. As my
business arrangements had not been very perfectly made, I lost the usual
amount."
Going to another extreme, we find Edison grappling with one of the
biggest problems known to the authorities of New York—the disposal of its
heavy snows. It is needless to say that witnessing the ordinary slow and
costly procedure would put Edison on his mettle. "One time when they had
a snow blockade in New York I started to build a machine with Batchelor—
a big truck with a steam-engine and compressor on it. We would run along
the street, gather all the snow up in front of us, pass it into the compressor,
and deliver little blocks of ice behind us in the gutter, taking one-tenth the
room of the snow, and not inconveniencing anybody. We could thus take
care of a snow-storm by diminishing the bulk of material to be handled. The
preliminary experiment we made was dropped because we went into other
things. The machine would go as fast as a horse could walk."
Edison has always taken a keen interest in aerial flight, and has also
experimented with aeroplanes, his preference inclining to the helicopter
type, as noted in the newspapers and periodicals from time to time. The
following statement from him refers to a type of aeroplane of great novelty
and ingenuity: "James Gordon Bennett came to me and asked that I try
some primary experiments to see if aerial navigation was feasible with
richest placer deposits in the United States, and various schemes had been
put forward to bring water from the mountains forty miles away to work

Page 387
'heavier-than-air' machines. I got up a motor and put it on the scales and
tried a large number of different things and contrivances connected to the
motor, to see how it would lighten itself on the scales. I got some data and
made up my mind that what was needed was a very powerful engine for its
weight, in small compass. So I conceived of an engine employing
guncotton. I took a lot of ticker paper tape, turned it into guncotton and got
up an engine with an arrangement whereby I could feed this gun-cotton
strip into the cylinder and explode it inside electrically. The feed took place
between two copper rolls. The copper kept the temperature down, so that it
could only explode up to the point where it was in contact with the feed
rolls. It worked pretty well; but once the feed roll didn't save it, and the
flame went through and exploded the whole roll and kicked up such a bad
explosion I abandoned it. But the idea might be made to work."
Turning from the air to the earth, it is interesting to note that the
introduction of the underground Edison system in New York made an
appeal to inventive ingenuity and that one of the difficulties was met as
follows: "When we first put the Pearl Street station in operation, in New
York, we had cast-iron junction-boxes at the intersections of all the streets.
One night, or about two o'clock in the morning, a policeman came in and
said that something had exploded at the corner of William and Nassau
streets. I happened to be in the station, and went out to see what it was. I
found that the cover of the manhole, weighing about 200 pounds, had
entirely disappeared, but everything inside was intact. It had even stripped
some of the threads of the bolts, and we could never find that cover. I
concluded it was either leakage of gas into the manhole, or else the acid
used in pickling the casting had given off hydrogen, and air had leaked in,
making an explosive mixture. As this was a pretty serious problem, and as
we had a good many of the manholes, it worried me very much for fear that
it would be repeated and the company might have to pay a lot of damages,
especially in districts like that around William and Nassau, where there are
a good many people about. If an explosion took place in the daytime it
might lift a few of them up. However, I got around the difficulty by putting
a little bottle of chloroform in each box, corked up, with a slight hole in the
cork. The chloroform being volatile and very heavy, settled in the box and
displaced all the air. I have never heard of an explosion in a manhole where
this chloroform had been used. Carbon tetrachloride, now made electrically
at Niagara Falls, is very cheap and would be ideal for the purpose."

Edison has never paid much attention to warfare, and has in general
disdained to develop inventions for the destruction of life and property.
Some years ago, however, he became the joint inventor of the Edison-Sims
torpedo, with Mr. W. Scott Sims, who sought his co-operation. This is a
dirigible submarine torpedo operated by electricity. In the torpedo proper,
which is suspended from a long float so as to be submerged a few feet
under water, are placed the small electric motor for propulsion and steering,
and the explosive charge. The torpedo is controlled from the shore or ship
through an electric cable which it pays out as it goes along, and all
operations of varying the speed, reversing, and steering are performed at the
will of the distant operator by means of currents sent through the cable.
During the Spanish-American War of 1898 Edison suggested to the Navy
Department the adoption of a compound of calcium carbide and calcium
phosphite, which when placed in a shell and fired from a gun would
explode as soon as it struck water and ignite, producing a blaze that would
continue several minutes and make the ships of the enemy visible for four
or five miles at sea. Moreover, the blaze could not be extinguished.
Edison has always been deeply interested in "conservation," and much of
his work has been directed toward the economy of fuel in obtaining
electrical energy directly from the consumption of coal. Indeed, it will be
noted that the example of his handwriting shown in these volumes deals
with the importance of obtaining available energy direct from the
combustible without the enormous loss in the intervening stages that makes
our best modern methods of steam generation and utilization so barbarously
extravagant and wasteful. Several years ago, experimenting in this field,
Edison devised and operated some ingenious pyromagnetic motors and
generators, based, as the name implies, on the direct application of heat to
the machines. The motor is founded upon the principle discovered by the
famous Dr. William Gilbert—court physician to Queen Elizabeth, and the
Father of modern electricity—that the magnetic properties of iron diminish
with heat. At a light-red heat, iron becomes non-magnetic, so that a strong
magnet exerts no influence over it. Edison employed this peculiar property
by constructing a small machine in which a pivoted bar is alternately heated
and cooled. It is thus attracted toward an adjacent electromagnet when cold
and is uninfluenced when hot, and as the result motion is produced.
The pyromagnetic generator is based on the same phenomenon; its aim
being of course to generate electrical energy directly from the heat of the
disdained to develop inventions for the destruction of life and property.

with heat. At a light-red heat, iron becomes non-magnetic, so that a strong
magnet exerts no influence over it. Edison employed this peculiar property
by constructing a small machine in which a pivoted bar is alternately heated
and cooled. It is thus attracted toward an adjacent electromagnet when cold
and is uninfluenced when hot, and as the result motion is produced.
The pyromagnetic generator is based on the same phenomenon; its aim
being of course to generate electrical energy directly from the heat of the
Page 389
combustible. The armature, or moving part of the machine, consists in
reality of eight separate armatures all constructed of corrugated sheet iron
covered with asbestos and wound with wire. These armatures are held in
place by two circular iron plates, through the centre of which runs a shaft,
carrying at its lower extremity a semicircular shield of fire-clay, which
covers the ends of four of the armatures. The heat, of whatever origin, is
applied from below, and the shaft being revolved, four of the armatures lose
their magnetism constantly, while the other four gain it, so to speak. As the
moving part revolves, therefore, currents of electricity are set up in the
wires of the armatures and are collected by a commutator, as in an ordinary
dynamo, placed on the upper end of the central shaft.
A great variety of electrical instruments are included in Edison's
inventions, many of these in fundamental or earlier forms being devised for
his systems of light and power, as noted already. There are numerous others,
and it might be said with truth that Edison is hardly ever without some new
device of this kind in hand, as he is by no means satisfied with the present
status of electrical measurements. He holds in general that the meters of to-
day, whether for heavy or for feeble currents, are too expensive, and that
cheaper instruments are a necessity of the times. These remarks apply more
particularly to what may be termed, in general, circuit meters. In other
classes Edison has devised an excellent form of magnetic bridge, being an
ingenious application of the principles of the familiar Wheatstone bridge,
used so extensively for measuring the electrical resistance of wires; the
testing of iron for magnetic qualities being determined by it in the same
way. Another special instrument is a "dead beat" galvanometer which
differs from the ordinary form of galvanometer in having no coils or
magnetic needle. It depends for its action upon the heating effect of the
current, which causes a fine platinum-iridium wire enclosed in a glass tube
to expand; thus allowing a coiled spring to act on a pivoted shaft carrying a
tiny mirror. The mirror as it moves throws a beam of light upon a scale and
the indications are read by the spot of light. Most novel of all the apparatus
of this measuring kind is the odoroscope, which is like the tasimeter
described in an earlier chapter, except that a strip of gelatine takes the place
of hard rubber, as the sensitive member. Besides being affected by heat, this
device is exceedingly sensitive to moisture. A few drops of water or
perfume thrown on the floor of a room are sufficient to give a very decided
indication on the galvanometer in circuit with the instrument. Barometers,

the character or pressure of gases and vapors in which it has been placed.
In the list of Edison's patents at the end of this work may be noted many
other of his miscellaneous inventions, covering items such as preserving
fruit in vacuo, making plate-glass, drawing wire, and metallurgical
processes for treatment of nickel, gold, and copper ores; but to mention
these inventions separately would trespass too much on our limited space
here. Hence, we shall leave the interested reader to examine that list for
himself.
From first to last Edison has filed in the United States Patent Office—in
addition to more than 1400 applications for patents—some 120 caveats
embracing not less than 1500 inventions. A "caveat" is essentially a notice
filed by an inventor, entitling him to receive warning from the Office of any
application for a patent for an invention that would "interfere" with his own,
during the year, while he is supposed to be perfecting his device. The old
caveat system has now been abolished, but it served to elicit from Edison a
most astounding record of ideas and possible inventions upon which he was
working, and many of which he of course reduced to practice. As an
example of Edison's fertility and the endless variety of subjects engaging
his thoughts, the following list of matters covered by ONE caveat is given.
It is needless to say that all the caveats are not quite so full of "plums," but
this is certainly a wonder.
Forty-one distinct inventions relating to the phonograph, covering
various forms of recorders, arrangement of parts, making of records,
shaving tool, adjustments, etc.
Eight forms of electric lamps using infusible earthy oxides and brought to
high incandescence in vacuo by high potential current of several thousand
volts; same character as impingement of X-rays on object in bulb.
A loud-speaking telephone with quartz cylinder and beam of ultra-violet
light.
Four forms of arc light with special carbons.
A thermostatic motor.
A device for sealing together the inside part and bulb of an incandescent
lamp mechanically.

Device for examining combinations of odors and their changes by

From one of the preceding items it will be noted that even in the eighties
Edison perceived much advantage to be gained in the line of economy by
the use of lamp filaments employing refractory metals in their construction.
From another caveat, filed in 1889, we extract the following, which shows
that he realized the value of tungsten also for this purpose. "Filaments of
carbon placed in a combustion tube with a little chloride ammonium.
Chloride tungsten or titanium passed through hot tube, depositing a film of
metal on the carbon; or filaments of zirconia oxide, or alumina or magnesia,
thoria or other infusible oxides mixed or separate, and obtained by
moistening and squirting through a die, are thus coated with above metals
and used for incandescent lamps. Osmium from a volatile compound of
same thus deposited makes a filament as good as carbon when in vacuo."
In 1888, long before there arose the actual necessity of duplicating
phonograph records so as to produce replicas in great numbers, Edison
described in one of his caveats a method and process much similar to the
one which was put into practice by him in later years. In the same caveat he
describes an invention whereby the power to indent on a phonograph
cylinder, instead of coming directly from the voice, is caused by power
derived from the rotation or movement of the phonogram surface itself. He
did not, however, follow up this invention and put it into practice. Some
twenty years later it was independently invented and patented by another
inventor. A further instance of this kind is a method of telegraphy at sea by
means of a diaphragm in a closed port-hole flush with the side of the vessel,
and actuated by a steam-whistle which is controlled by a lever, similarly to
a Morse key. A receiving diaphragm is placed in another and near-by
chamber, which is provided with very sensitive stethoscopic ear-pieces, by
which the Morse characters sent from another vessel may be received. This
was also invented later by another inventor, and is in use to-day, but will
naturally be rivalled by wireless telegraphy. Still another instance is seen in
of metallic salts.

one of Edison's caveats, where he describes a method of distilling liquids by
means of internally applied heat through electric conductors. Although
Edison did not follow up the idea and take out a patent, this system of
distillation was later hit upon by others and is in use at the present time.
In the foregoing pages of this chapter the authors have endeavored to
present very briefly a sketchy notion of the astounding range of Edison's
practical ideas, but they feel a sense of impotence in being unable to deal
adequately with the subject in the space that can be devoted to it. To those
who, like the authors, have had the privilege of examining the voluminous
records which show the flights of his imagination, there comes a feeling of
utter inadequacy to convey to others the full extent of the story they reveal.
The few specific instances above related, although not representing a

CHAPTER XXIV
EDISON'S METHOD IN INVENTING
WHILE the world's progress depends largely upon their ingenuity,
inventors are not usually persons who have adopted invention as a distinct
profession, but, generally speaking, are otherwise engaged in various walks
of life. By reason of more or less inherent native genius they either make
improvements along lines of present occupation, or else evolve new
methods and means of accomplishing results in fields for which they may
have personal predilections.
Now and then, however, there arises a man so greatly endowed with
natural powers and originality that the creative faculty within him is too
strong to endure the humdrum routine of affairs, and manifests itself in a
life devoted entirely to the evolution of methods and devices calculated to
further the world's welfare. In other words, he becomes an inventor by
profession. Such a man is Edison. Notwithstanding the fact that nearly forty
years ago (not a great while after he had emerged from the ranks of
peripatetic telegraph operators) he was the owner of a large and profitable
business as a manufacturer of the telegraphic apparatus invented by him,
the call of his nature was too strong to allow of profits being laid away in
the bank to accumulate. As he himself has said, he has "too sanguine a
temperament to allow money to stay in solitary confinement." Hence, all
superfluous cash was devoted to experimentation. In the course of years he
grew more and more impatient of the shackles that bound him to business
routine, and, realizing the powers within him, he drew away gradually from
purely manufacturing occupations, determining deliberately to devote his
life to inventive work, and to depend upon its results as a means of
subsistence.
All persons who make inventions will necessarily be more or less
original in character, but to the man who chooses to become an inventor by
profession must be conceded a mind more than ordinarily replete with
virility and originality. That these qualities in Edison are superabundant is
well known to all who have worked with him, and, indeed, are apparent to

well known to all who have worked with him, and, indeed, are apparent to
Page 396
every one from his multiplied achievements within the period of one
generation.
If one were allowed only two words with which to describe Edison, it is
doubtful whether a close examination of the entire dictionary would
disclose any others more suitable than "experimenter—inventor." These
would express the overruling characteristics of his eventful career. It is as
an "inventor" that he sets himself down in the membership list of the
American Institute of Electrical Engineers. To attempt the strict placing of
these words in relation to each other (except alphabetically) would be equal
to an endeavor to solve the old problem as to which came first, the egg or
the chicken; for although all his inventions have been evolved through
experiment, many of his notable experiments have called forth the exercise
of highly inventive faculties in their very inception. Investigation and
experiment have been a consuming passion, an impelling force from within,
as it were, from his petticoat days when he collected goose-eggs and tried to
hatch them out by sitting over them himself. One might be inclined to
dismiss this trivial incident smilingly, as a mere childish, thoughtless prank,
had not subsequent development as a child, boy, and man revealed a born
investigator with original reasoning powers that, disdaining crooks and
bends, always aimed at the centre, and, like the flight of the bee, were
accurate and direct.
It is not surprising, therefore, that a man of this kind should exhibit a
ceaseless, absorbing desire for knowledge, and an apparently uncontrollable
tendency to experiment on every possible occasion, even though his last
cent were spent in thus satisfying the insatiate cravings of an inquiring
mind.
During Edison's immature years, when he was flitting about from place
to place as a telegraph operator, his experimentation was of a desultory,
hand-to-mouth character, although it was always notable for originality, as
expressed in a number of minor useful devices produced during this period.
Small wonder, then, that at the end of these wanderings, when he had found
a place to "rest the sole of his foot," he established a laboratory in which to
carry on his researches in a more methodical and practical manner. In this
was the beginning of the work which has since made such a profound
impression on contemporary life.

There is nothing of the helter-skelter, slap-dash style in Edison's
experiments. Although all the laboratory experimenters agree in the opinion
that he "tries everything," it is not merely the mixing of a little of this, some
of that, and a few drops of the other, in the HOPE that SOMETHING will
come of it. Nor is the spirit of the laboratory work represented in the
following dialogue overheard between two alleged carpenters picked up at
random to help on a hurry job.
"How near does she fit, Mike?"
"About an inch."
"Nail her!"
A most casual examination of any of the laboratory records will reveal
evidence of the minutest exactitude insisted on in the conduct of
experiments, irrespective of the length of time they occupied. Edison's
instructions, always clear cut and direct, followed by his keen oversight,
admit of nothing less than implicit observance in all details, no matter
where they may lead, and impel to the utmost minuteness and accuracy.
To some extent there has been a popular notion that many of Edison's
successes have been due to mere dumb fool luck—to blind, fortuitous
"happenings." Nothing could be further from the truth, for, on the contrary,
it is owing almost entirely to the comprehensive scope of his knowledge,
the breadth of his conception, the daring originality of his methods, and
minuteness and extent of experiment, combined with unwavering
pertinacity, that new arts have been created and additions made to others
already in existence. Indeed, without this tireless minutiae, and methodical,
searching spirit, it would have been practically impossible to have produced
many of the most important of these inventions.
Needless to say, mastery of its literature is regarded by him as a most
important preliminary in taking up any line of investigation. What others
may have done, bearing directly or collaterally on the subject, in print, is
carefully considered and sifted to the point of exhaustion. Not that he takes
it for granted that the conclusions are correct, for he frequently obtains
vastly different results by repeating in his own way experiments made by
others as detailed in books.
"Edison can travel along a well-used road and still find virgin soil,"
remarked recently one of his most practical experimenters, who had been
working along a certain line without attaining the desired result. "He

"Edison can travel along a well-used road and still find virgin soil,"
remarked recently one of his most practical experimenters, who had been
working along a certain line without attaining the desired result. "He
Page 398
wanted to get a particular compound having definite qualities, and I had
tried in all sorts of ways to produce it but with only partial success. He was
confident that it could be done, and said he would try it himself. In doing so
he followed the same path in which I had travelled, but, by making an
undreamed-of change in one of the operations, succeeded in producing a
compound that virtually came up to his specifications. It is not the only time
I have known this sort of thing to happen."
In speaking of Edison's method of experimenting, another of his
laboratory staff says: "He is never hindered by theory, but resorts to actual
experiment for proof. For instance, when he conceived the idea of pouring a
complete concrete house it was universally held that it would be impossible
because the pieces of stone in the mixture would not rise to the level of the
pouring-point, but would gravitate to a lower plane in the soft cement. This,
however, did not hinder him from making a series of experiments which
resulted in an invention that proved conclusively the contrary."
Having conceived some new idea and read everything obtainable relating
to the subject in general, Edison's fertility of resource and originality come
into play. Taking one of the laboratory note-books, he will write in it a
memorandum of the experiments to be tried, illustrated, if necessary, by
sketches. This book is then passed on to that member of the experimental
staff whose special training and experience are best adapted to the work.
Here strenuousness is expected; and an immediate commencement of
investigation and prompt report are required. Sometimes the subject may be
such as to call for a long line of frequent tests which necessitate patient and
accurate attention to minute details. Results must be reported often—daily,
or possibly with still greater frequency. Edison does not forget what is
going on; but in his daily tours through the laboratory keeps in touch with
all the work that is under the hands of his various assistants, showing by an
instant grasp of the present conditions of any experiment that he has a full
consciousness of its meaning and its reference to his original conception.
The year 1869 saw the beginning of Edison's career as an acknowledged
inventor of commercial devices. From the outset, an innate recognition of
system dictated the desirability and wisdom of preserving records of his
experiments and inventions. The primitive records, covering the earliest
years, were mainly jotted down on loose sheets of paper covered with
sketches, notes, and data, pasted into large scrap-books, or preserved in
tried in all sorts of ways to produce it but with only partial success. He was
confident that it could be done, and said he would try it himself. In doing so
he followed the same path in which I had travelled, but, by making an
undreamed-of change in one of the operations, succeeded in producing a
compound that virtually came up to his specifications. It is not the only time
I have known this sort of thing to happen."
In speaking of Edison's method of experimenting, another of his
laboratory staff says: "He is never hindered by theory, but resorts to actual
experiment for proof. For instance, when he conceived the idea of pouring a
complete concrete house it was universally held that it would be impossible
because the pieces of stone in the mixture would not rise to the level of the
pouring-point, but would gravitate to a lower plane in the soft cement. This,
however, did not hinder him from making a series of experiments which
resulted in an invention that proved conclusively the contrary."
Having conceived some new idea and read everything obtainable relating
to the subject in general, Edison's fertility of resource and originality come
into play. Taking one of the laboratory note-books, he will write in it a
memorandum of the experiments to be tried, illustrated, if necessary, by
sketches. This book is then passed on to that member of the experimental
staff whose special training and experience are best adapted to the work.
Here strenuousness is expected; and an immediate commencement of
investigation and prompt report are required. Sometimes the subject may be
such as to call for a long line of frequent tests which necessitate patient and
accurate attention to minute details. Results must be reported often—daily,

Page 399
packages; but with the passing of years and enlargement of his interests, it
became the practice to make all original laboratory notes in large, uniform
books. This course was pursued until the Menlo Park period, when he
instituted a new regime that has been continued down to the present day. A
standard form of note-book, about eight and a half by six inches, containing
about two hundred pages, was adopted. A number of these books were (and
are now) always to be found scattered around in the different sections of the
laboratory, and in them have been noted by Edison all his ideas, sketches,
and memoranda. Details of the various experiments concerning them have
been set down by his assistants from time to time.
These later laboratory note-books, of which there are now over one
thousand in the series, are eloquent in the history they reveal of the
strenuous labors of Edison and his assistants and the vast fields of research
he has covered during the last thirty years. They are overwhelmingly rich in
biographic material, but analysis would be a prohibitive task for one person,
and perhaps interesting only to technical readers. Their pages cover
practically every department of science. The countless thousands of
separate experiments recorded exhibit the operations of a master mind
seeking to surprise Nature into a betrayal of her secrets by asking her the
same question in a hundred different ways. For instance, when Edison was
investigating a certain problem of importance many years ago, the note-
books show that on this point alone about fifteen thousand experiments and
tests were made by one of his assistants.
A most casual glance over these note-books will illustrate the following
remark, which was made to one of the writers not long ago by a member of
the laboratory staff who has been experimenting there for twenty years:
"Edison can think of more ways of doing a thing than any man I ever saw or
heard of. He tries everything and never lets up, even though failure is
apparently staring him in the face. He only stops when he simply can't go
any further on that particular line. When he decides on any mode of
procedure he gives his notes to the experimenter and lets him alone, only
stepping in from time to time to look at the operations and receive reports
of progress."
The history of the development of the telephone transmitter, phonograph,
incandescent lamp, dynamo, electrical distributing systems from central
stations, electric railway, ore-milling, cement, motion pictures, and a host of
became the practice to make all original laboratory notes in large, uniform

The history of the development of the telephone transmitter, phonograph,
incandescent lamp, dynamo, electrical distributing systems from central
stations, electric railway, ore-milling, cement, motion pictures, and a host of
Page 400
minor inventions may be found embedded in the laboratory note-books. A
passing glance at a few pages of these written records will serve to
illustrate, though only to a limited extent, the thoroughness of Edison's
method. It is to be observed that these references can be but of the most
meagre kind, and must be regarded as merely throwing a side-light on the
subject itself. For instance, the complex problem of a practical telephone
transmitter gave rise to a series of most exhaustive experiments.
Combinations in almost infinite variety, including gums, chemical
compounds, oils, minerals, and metals were suggested by Edison; and his
assistants were given long lists of materials to try with reference to
predetermined standards of articulation, degrees of loudness, and perfection
of hissing sounds. The note-books contain hundreds of pages showing that a
great many thousands of experiments were tried and passed upon. Such
remarks as "N. G."; "Pretty good"; "Whistling good, but no articulation";
"Rattly"; "Articulation, whispering, and whistling good"; "Best to-night so
far"; and others are noted opposite the various combinations as they were
tried. Thus, one may follow the investigation through a maze of
experiments which led up to the successful invention of the carbon button
transmitter, the vital device to give the telephone its needed articulation and
perfection.
The two hundred and odd note-books, covering the strenuous period
during which Edison was carrying on his electric-light experiments, tell on
their forty thousand pages or more a fascinating story of the evolution of a
new art in its entirety. From the crude beginnings, through all the varied
phases of this evolution, the operations of a master mind are apparent from
the contents of these pages, in which are recorded the innumerable
experiments, calculations, and tests that ultimately brought light out of
darkness.
The early work on a metallic conductor for lamps gave rise to some very
thorough research on melting and alloying metals, the preparation of
metallic oxides, the coating of fine wires by immersing them in a great
variety of chemical solutions. Following his usual custom, Edison would
indicate the lines of experiment to be followed, which were carried out and
recorded in the note-books. He himself, in January, 1879, made personally a
most minute and searching investigation into the properties and behavior of
plating-iridium, boron, rutile, zircon, chromium, molybdenum, and nickel,
under varying degrees of current strength, on which there may be found in

Page 401
the notes about forty pages of detailed experiments and deductions in his
own handwriting, concluding with the remark (about nickel): "This is a
great discovery for electric light in the way of economy."
This period of research on nickel, etc., was evidently a trying one, for
after nearly a month's close application he writes, on January 27, 1879:
"Owing to the enormous power of the light my eyes commenced to pain
after seven hours' work, and I had to quit." On the next day appears the
following entry: "Suffered the pains of hell with my eyes last night from 10
P.M. till 4 A.M., when got to sleep with a big dose of morphine. Eyes
getting better, and do not pain much at 4 P.M.; but I lose to-day."
The "try everything" spirit of Edison's method is well illustrated in this
early period by a series of about sixteen hundred resistance tests of various
ores, minerals, earths, etc., occupying over fifty pages of one of the note-
books relating to the metallic filament for his lamps.
But, as the reader has already learned, the metallic filament was soon laid
aside in favor of carbon, and we find in the laboratory notes an amazing
record of research and experiment conducted in the minute and searching
manner peculiar to Edison's method. His inquiries were directed along all
the various roads leading to the desired goal, for long before he had
completed the invention of a practical lamp he realized broadly the
fundamental requirements of a successful system of electrical distribution,
and had given instructions for the making of a great variety of calculations
which, although far in advance of the time, were clearly foreseen by him to
be vitally important in the ultimate solution of the complicated problem.
Thus we find many hundreds of pages of the note-books covered with
computations and calculations by Mr. Upton, not only on the numerous
ramifications of the projected system and comparisons with gas, but also on
proposed forms of dynamos and the proposed station in New York. A mere
recital by titles of the vast number of experiments and tests on carbons,
lamps, dynamos, armatures, commutators, windings, systems, regulators,
sockets, vacuum-pumps, and the thousand and one details relating to the
subject in general, originated by Edison, and methodically and
systematically carried on under his general direction, would fill a great
many pages here, and even then would serve only to convey a confused
impression of ceaseless probing.

It is possible only to a broad, comprehensive mind well stored with
knowledge, and backed with resistless, boundless energy, that such a
diversified series of experiments and investigations could be carried on
simultaneously and assimilated, even though they should relate to a class of
phenomena already understood and well defined. But if we pause to
consider that the commercial subdivision of the electric current (which was
virtually an invention made to order) involved the solution of problems so
unprecedented that even they themselves had to be created, we cannot but
conclude that the afflatus of innate genius played an important part in the
unique methods of investigation instituted by Edison at that and other times.
The idea of attributing great successes to "genius" has always been
repudiated by Edison, as evidenced by his historic remark that "Genius is 1
per cent. inspiration and 99 per cent. perspiration." Again, in a conversation
many years ago at the laboratory between Edison, Batchelor, and E. H.
Johnson, the latter made allusion to Edison's genius as evidenced by some
of his achievements, when Edison replied:
"Stuff! I tell you genius is hard work, stick-to-it-iveness, and common
sense."
"Yes," said Johnson, "I admit there is all that to it, but there's still more.
Batch and I have those qualifications, but although we knew quite a lot
about telephones, and worked hard, we couldn't invent a brand-new non-
infringing telephone receiver as you did when Gouraud cabled for one.
Then, how about the subdivision of the electric light?"
"Electric current," corrected Edison.
"True," continued Johnson; "you were the one to make that very
distinction. The scientific world had been working hard on subdivision for
years, using what appeared to be common sense. Results worse than nil.
Then you come along, and about the first thing you do, after looking the
ground over, is to start off in the opposite direction, which subsequently
proves to be the only possible way to reach the goal. It seems to me that this
is pretty close to the dictionary definition of genius."
It is said that Edison replied rather incoherently and changed the topic of
conversation.
This innate modesty, however, does not prevent Edison from recognizing
and classifying his own methods of investigation. In a conversation with
two old associates recently (April, 1909), he remarked: "It has been said of
knowledge, and backed with resistless, boundless energy, that such a
diversified series of experiments and investigations could be carried on
simultaneously and assimilated, even though they should relate to a class of

two old associates recently (April, 1909), he remarked: "It has been said of
Page 403
me that my methods are empirical. That is true only so far as chemistry is
concerned. Did you ever realize that practically all industrial chemistry is
colloidal in its nature? Hard rubber, celluloid, glass, soap, paper, and lots of
others, all have to deal with amorphous substances, as to which
comparatively little has been really settled. My methods are similar to those
followed by Luther Burbank. He plants an acre, and when this is in bloom
he inspects it. He has a sharp eye, and can pick out of thousands a single
plant that has promise of what he wants. From this he gets the seed, and
uses his skill and knowledge in producing from it a number of new plants
which, on development, furnish the means of propagating an improved
variety in large quantity. So, when I am after a chemical result that I have in
mind, I may make hundreds or thousands of experiments out of which there
may be one that promises results in the right direction. This I follow up to
its legitimate conclusion, discarding the others, and usually get what I am
after. There is no doubt about this being empirical; but when it comes to
problems of a mechanical nature, I want to tell you that all I've ever tackled
and solved have been done by hard, logical thinking." The intense
earnestness and emphasis with which this was said were very impressive to
the auditors. This empirical method may perhaps be better illustrated by a
specific example. During the latter part of the storage battery investigations,
after the form of positive element had been determined upon, it became
necessary to ascertain what definite proportions and what quality of nickel
hydrate and nickel flake would give the best results. A series of positive
tubes were filled with the two materials in different proportions—say, nine
parts hydrate to one of flake; eight parts hydrate to two of flake; seven parts
hydrate to three of flake, and so on through varying proportions. Three sets
of each of these positives were made, and all put into separate test tubes
with a uniform type of negative element. These were carried through a long
series of charges and discharges under strict test conditions. From the
tabulated results of hundreds of tests there were selected three that showed
the best results. These, however, showed only the superiority of certain
PROPORTIONS of the materials. The next step would be to find out the
best QUALITY. Now, as there are several hundred variations in the quality
of nickel flake, and perhaps a thousand ways to make the hydrate, it will be
realized that Edison's methods led to stupendous detail, for these tests
embraced a trial of all the qualities of both materials in the three proportions
found to be most suitable. Among these many thousands of experiments any

Page 404
that showed extraordinary results were again elaborated by still further
series of tests, until Edison was satisfied that he had obtained the best result
in that particular line.
The laboratory note-books do not always tell the whole story or meaning
of an experiment that may be briefly outlined on one of their pages. For
example, the early filament made of a mixture of lampblack and tar is
merely a suggestion in the notes, but its making afforded an example of
Edison's pertinacity. These materials, when mixed, became a friable mass,
which he had found could be brought into such a cohesive, putty-like state
by manipulation, as to be capable of being rolled out into filaments as fine
as seven-thousandths of an inch in cross-section. One of the laboratory
assistants was told to make some of this mixture, knead it, and roll some
filaments. After a time he brought the mass to Edison, and said:
"There's something wrong about this, for it crumbles even after
manipulating it with my fingers."
"How long did you knead it?" said Edison.
"Oh! more than an hour," replied the assistant.
"Well, just keep on for a few hours more and it will come out all right,"
was the rejoinder. And this proved to be correct, for, after a prolonged
kneading and rolling, the mass changed into a cohesive, stringy,
homogeneous putty. It was from a mixture of this kind that spiral filaments
were made and used in some of the earliest forms of successful
incandescent lamps; indeed, they are described and illustrated in Edison's
fundamental lamp patent (No. 223,898).
The present narrative would assume the proportions of a history of the
incandescent lamp, should the authors attempt to follow Edison's
investigations through the thousands of pages of note-books away back in
the eighties and early nineties. Improvement of the lamp was constantly in
his mind all those years, and besides the vast amount of detail experimental
work he laid out for his assistants, he carried on a great deal of research
personally. Sometimes whole books are filled in his own handwriting with
records of experiments showing every conceivable variation of some
particular line of inquiry; each trial bearing some terse comment expressive
of results. In one book appear the details of one of these experiments on
September 3, 1891, at 4.30 A.M., with the comment: "Brought up lamp
higher than a 16-c.p. 240 was ever brought before—Hurrah!"

Page 405
Notwithstanding the late hour, he turns over to the next page and goes on to
write his deductions from this result as compared with those previously
obtained. Proceeding day by day, as appears by this same book, he follows
up another line of investigation on lamps, apparently full of difficulty, for
after one hundred and thirty-two other recorded experiments we find this
note: "Saturday 3.30 went home disgusted with incandescent lamps." This
feeling was evidently evanescent, for on the succeeding Monday the work
was continued and carried on by him as keenly as before, as shown by the
next batch of notes.
This is the only instance showing any indication of impatience that the
authors have found in looking through the enormous mass of laboratory
notes. All his assistants agree that Edison is the most patient, tireless
experimenter that could be conceived of. Failures do not distress him;
indeed, he regards them as always useful, as may be gathered from the
following, related by Dr. E. G. Acheson, formerly one of his staff: "I once
made an experiment in Edison's laboratory at Menlo Park during the latter
part of 1880, and the results were not as looked for. I considered the
experiment a perfect failure, and while bemoaning the results of this
apparent failure Mr. Edison entered, and, after learning the facts of the case,
cheerfully remarked that I should not look upon it as a failure, for he
considered every experiment a success, as in all cases it cleared up the
atmosphere, and even though it failed to accomplish the results sought for,
it should prove a valuable lesson for guidance in future work. I believe that
Mr. Edison's success as an experimenter was, to a large extent, due to this
happy view of all experiments."
Edison has frequently remarked that out of a hundred experiments he
does not expect more than one to be successful, and as to that one he is
always suspicious until frequent repetition has verified the original results.
This patient, optimistic view of the outcome of experiments has remained
part of his character down to this day, just as his painstaking, minute,
incisive methods are still unchanged. But to the careless, stupid, or lazy
person he is a terror for the short time they remain around him. Honest
mistakes may be tolerated, but not carelessness, incompetence, or lack of
attention to business. In such cases Edison is apt to express himself freely
and forcibly, as when he was asked why he had parted with a certain man,
he said: "Oh, he was so slow that it would take him half an hour to get out
write his deductions from this result as compared with those previously
obtained. Proceeding day by day, as appears by this same book, he follows
up another line of investigation on lamps, apparently full of difficulty, for
after one hundred and thirty-two other recorded experiments we find this
note: "Saturday 3.30 went home disgusted with incandescent lamps." This
feeling was evidently evanescent, for on the succeeding Monday the work
was continued and carried on by him as keenly as before, as shown by the
next batch of notes.
This is the only instance showing any indication of impatience that the
authors have found in looking through the enormous mass of laboratory
notes. All his assistants agree that Edison is the most patient, tireless
experimenter that could be conceived of. Failures do not distress him;
indeed, he regards them as always useful, as may be gathered from the
following, related by Dr. E. G. Acheson, formerly one of his staff: "I once
made an experiment in Edison's laboratory at Menlo Park during the latter
part of 1880, and the results were not as looked for. I considered the
experiment a perfect failure, and while bemoaning the results of this
apparent failure Mr. Edison entered, and, after learning the facts of the case,
cheerfully remarked that I should not look upon it as a failure, for he
considered every experiment a success, as in all cases it cleared up the
atmosphere, and even though it failed to accomplish the results sought for,
it should prove a valuable lesson for guidance in future work. I believe that
Mr. Edison's success as an experimenter was, to a large extent, due to this
happy view of all experiments."
Edison has frequently remarked that out of a hundred experiments he
does not expect more than one to be successful, and as to that one he is
always suspicious until frequent repetition has verified the original results.

part of his character down to this day, just as his painstaking, minute,
incisive methods are still unchanged. But to the careless, stupid, or lazy
person he is a terror for the short time they remain around him. Honest
mistakes may be tolerated, but not carelessness, incompetence, or lack of

and forcibly, as when he was asked why he had parted with a certain man,
he said: "Oh, he was so slow that it would take him half an hour to get out
Page 406
of the field of a microscope." Another instance will be illustrative. Soon
after the Brockton (Massachusetts) central station was started in operation
many years ago, he wrote a note to Mr. W. S. Andrews, containing
suggestions as to future stations, part of which related to the various
employees and their duties. After outlining the duties of the meter man,
Edison says: "I should not take too young a man for this, say, a man from
twenty-three to thirty years old, bright and businesslike. Don't want any one
who yearns to enter a laboratory and experiment. We have a bad case of that
at Brockton; he neglects business to potter. What we want is a good lamp
average and no unprofitable customer. You should have these men on
probation and subject to passing an examination by me. This will wake
them up."
Edison's examinations are no joke, according to Mr. J. H. Vail, formerly
one of the Menlo Park staff. "I wanted a job," he said, "and was ambitious
to take charge of the dynamo-room. Mr. Edison led me to a heap of junk in
a corner and said: 'Put that together and let me know when it's running.' I
didn't know what it was, but received a liberal education in finding out. It
proved to be a dynamo, which I finally succeeded in assembling and
running. I got the job." Another man who succeeded in winning a place as
assistant was Mr. John F. Ott, who has remained in his employ for over
forty years. In 1869, when Edison was occupying his first manufacturing
shop (the third floor of a small building in Newark), he wanted a first-class
mechanician, and Mr. Ott was sent to him. "He was then an ordinary-
looking young fellow," says Mr. Ott, "dirty as any of the other workmen,
unkempt, and not much better dressed than a tramp, but I immediately felt
that there was a great deal in him." This is the conversation that ensued, led
by Mr. Edison's question:
"What do you want?"
"Work."
"Can you make this machine work?" (exhibiting it and explaining its
details).
"Yes."
"Are you sure?"
"Well, you needn't pay me if I don't."

And thus Mr. Ott went to work and succeeded in accomplishing the
results desired. Two weeks afterward Mr. Edison put him in charge of the
shop.
Edison's life fairly teems with instances of unruffled patience in the
pursuit of experiments. When he feels thoroughly impressed with the
possibility of accomplishing a certain thing, he will settle down composedly
to investigate it to the end.
This is well illustrated in a story relating to his invention of the type of
storage battery bearing his name. Mr. W. S. Mallory, one of his closest
associates for many years, is the authority for the following: "When Mr.
Edison decided to shut down the ore-milling plant at Edison, New Jersey, in
which I had been associated with him, it became a problem as to what he
could profitably take up next, and we had several discussions about it. He
finally thought that a good storage battery was a great requisite, and decided
to try and devise a new type, for he declared emphatically he would make
no battery requiring sulphuric acid. After a little thought he conceived the
nickel-iron idea, and started to work at once with characteristic energy.
About 7 or 7.30 A.M. he would go down to the laboratory and experiment,
only stopping for a short time at noon to eat a lunch sent down from the
house. About 6 o'clock the carriage would call to take him to dinner, from
which he would return by 7.30 or 8 o'clock to resume work. The carriage
came again at midnight to take him home, but frequently had to wait until 2
or 3 o'clock, and sometimes return without him, as he had decided to
continue all night.
"This had been going on more than five months, seven days a week,
when I was called down to the laboratory to see him. I found him at a bench
about three feet wide and twelve to fifteen feet long, on which there were
hundreds of little test cells that had been made up by his corps of chemists
and experimenters. He was seated at this bench testing, figuring, and
planning. I then learned that he had thus made over nine thousand
experiments in trying to devise this new type of storage battery, but had not
produced a single thing that promised to solve the question. In view of this
immense amount of thought and labor, my sympathy got the better of my
judgment, and I said: 'Isn't it a shame that with the tremendous amount of
work you have done you haven't been able to get any results?' Edison
results desired. Two weeks afterward Mr. Edison put him in charge of the
shop.

Page 408
turned on me like a flash, and with a smile replied: 'Results! Why, man, I
have gotten a lot of results! I know several thousand things that won't work.'
"At that time he sent me out West on a special mission. On my return, a
few weeks later, his experiments had run up to over ten thousand, but he
had discovered the missing link in the combination sought for. Of course,
we all remember how the battery was completed and put on the market.
Then, because he was dissatisfied with it, he stopped the sales and
commenced a new line of investigation, which has recently culminated
successfully. I shouldn't wonder if his experiments on the battery ran up
pretty near to fifty thousand, for they fill more than one hundred and fifty of
the note-books, to say nothing of some thousands of tests in curve sheets."
Although Edison has an absolute disregard for the total outlay of money
in investigation, he is particular to keep down the cost of individual
experiments to a minimum, for, as he observed to one of his assistants: "A
good many inventors try to develop things life-size, and thus spend all their
money, instead of first experimenting more freely on a small scale." To
Edison life is not only a grand opportunity to find out things by experiment,
but, when found, to improve them by further experiment. One night, after
receiving a satisfactory report of progress from Mr. Mason, superintendent
of the cement plant, he said: "The only way to keep ahead of the procession
is to experiment. If you don't, the other fellow will. When there's no
experimenting there's no progress. Stop experimenting and you go
backward. If anything goes wrong, experiment until you get to the very
bottom of the trouble."
It is easy to realize, therefore, that a character so thoroughly permeated
with these ideas is not apt to stop and figure out expense when in hot
pursuit of some desired object. When that object has been attained,
however, and it passes from the experimental to the commercial stage,
Edison's monetary views again come into strong play, but they take a
diametrically opposite position, for he then begins immediately to plan the
extreme of economy in the production of the article. A thousand and one
instances could be quoted in illustration; but as they would tend to change
the form of this narrative into a history of economy in manufacture, it will
suffice to mention but one, and that a recent occurrence, which serves to
illustrate how closely he keeps in touch with everything, and also how the
inventive faculty and instinct of commercial economy run close together. It
have gotten a lot of results! I know several thousand things that won't work.'

Page 409
was during Edison's winter stay in Florida, in March, 1909. He had reports
sent to him daily from various places, and studied them carefully, for he
would write frequently with comments, instructions, and suggestions; and
in one case, commenting on the oiling system at the cement plant, he wrote:
"Your oil losses are now getting lower, I see." Then, after suggesting some
changes to reduce them still further, he went on to say: "Here is a chance to
save a mill per barrel based on your regular daily output."
This thorough consideration of the smallest detail is essentially
characteristic of Edison, not only in economy of manufacture, but in all his
work, no matter of what kind, whether it be experimenting, investigating,
testing, or engineering. To follow him through the labyrinthine paths of
investigation contained in the great array of laboratory note-books is to
become involved in a mass of minutely detailed searches which seek to
penetrate the inmost recesses of nature by an ultimate analysis of an infinite
variety of parts. As the reader will obtain a fuller comprehension of this
idea, and of Edison's methods, by concrete illustration rather than by
generalization, the authors have thought it well to select at random two
typical instances of specific investigations out of the thousands that are
scattered through the notebooks. These will be found in the following
extracts from one of the note-books, and consist of Edison's instructions to
be carried out in detail by his experimenters:
"Take, say, 25 lbs. hard Cuban asphalt and separate all the different
hydrocarbons, etc., as far as possible by means of solvents. It will be
necessary first to dissolve everything out by, say, hot turpentine, then
successively treat the residue with bisulphide carbon, benzol, ether,
chloroform, naphtha, toluol, alcohol, and other probable solvents. After you
can go no further, distil off all the solvents so the asphalt material has a tar-
like consistency. Be sure all the ash is out of the turpentine portion; now,
after distilling the turpentine off, act on the residue with all the solvents that
were used on the residue, using for the first the solvent which is least likely
to dissolve a great part of it. By thus manipulating the various solvents you
will be enabled probably to separate the crude asphalt into several distinct
hydrocarbons. Put each in a bottle after it has been dried, and label the
bottle with the process, etc., so we may be able to duplicate it; also give
bottle a number and describe everything fully in note-book."

"Destructively distil the following substances down to a point just short
of carbonization, so that the residuum can be taken out of the retort,
powdered, and acted on by all the solvents just as the asphalt in previous
page. The distillation should be carried to, say, 600 degrees or 700 degrees
Fahr., but not continued long enough to wholly reduce mass to charcoal, but
always run to blackness. Separate the residuum in as many definite parts as
possible, bottle and label, and keep accurate records as to process, weights,
etc., so a reproduction of the experiment can at any time be made: Gelatine,
4 lbs.; asphalt, hard Cuban, 10 lbs.; coal-tar or pitch, 10 lbs.; wood-pitch, 10
lbs.; Syrian asphalt, 10 lbs.; bituminous coal, 10 lbs.; cane-sugar, 10 lbs.;
glucose, 10 lbs.; dextrine, 10 lbs.; glycerine, 10 lbs.; tartaric acid, 5 lbs.;
gum guiac, 5 lbs.; gum amber, 3 lbs.; gum tragacanth, 3 Lbs.; aniline red, 1
lb.; aniline oil, 1 lb.; crude anthracene, 5 lbs.; petroleum pitch, 10 lbs.;

lbs.; citric acid, 5 lbs.; sawdust of boxwood, 3 lbs.; starch, 5 lbs.; shellac, 3
lbs.; gum Arabic, 5 lbs.; castor oil, 5 lbs."
The empirical nature of his method will be apparent from an examination
of the above items; but in pursuing it he leaves all uncertainty behind and,
trusting nothing to theory, he acquires absolute knowledge. Whatever may
be the mental processes by which he arrives at the starting-point of any
specific line of research, the final results almost invariably prove that he
does not plunge in at random; indeed, as an old associate remarked: "When
Edison takes up any proposition in natural science, his perceptions seem to
be elementally broad and analytical, that is to say, in addition to the
knowledge he has acquired from books and observation, he appears to have
an intuitive apprehension of the general order of things, as they might be
supposed to exist in natural relation to each other. It has always seemed to
me that he goes to the core of things at once."
Although nothing less than results from actual experiments are
acceptable to him as established facts, this view of Edison may also account
for his peculiar and somewhat weird ability to "guess" correctly, a faculty
which has frequently enabled him to take short cuts to lines of investigation
whose outcome has verified in a most remarkable degree statements
apparently made offhand and without calculation. Mr. Upton says: "One of
the main impressions left upon me, after knowing Mr. Edison for many
years, is the marvellous accuracy of his guesses. He will see the general
nature of a result long before it can be reached by mathematical
of carbonization, so that the residuum can be taken out of the retort,

nature of a result long before it can be reached by mathematical
Page 411
calculation." This was supplemented by one of his engineering staff, who
remarked: "Mr. Edison can guess better than a good many men can figure,
and so far as my experience goes, I have found that he is almost invariably
correct. His guess is more than a mere starting-point, and often turns out to
be the final solution of a problem. I can only account for it by his
remarkable insight and wonderful natural sense of the proportion of things,
in addition to which he seems to carry in his head determining factors of all
kinds, and has the ability to apply them instantly in considering any
mechanical problem."
While this mysterious intuitive power has been of the greatest advantage
in connection with the vast number of technical problems that have entered
into his life-work, there have been many remarkable instances in which it
has seemed little less than prophecy, and it is deemed worth while to digress
to the extent of relating two of them. One day in the summer of 1881, when
the incandescent lamp-industry was still in swaddling clothes, Edison was
seated in the room of Major Eaton, vice-president of the Edison Electric
Light Company, talking over business matters, when Mr. Upton came in
from the lamp factory at Menlo Park, and said: "Well, Mr. Edison, we
completed a thousand lamps to-day." Edison looked up and said "Good,"
then relapsed into a thoughtful mood. In about two minutes he raised his
head, and said: "Upton, in fifteen years you will be making forty thousand
lamps a day." None of those present ventured to make any remark on this
assertion, although all felt that it was merely a random guess, based on the
sanguine dream of an inventor. The business had not then really made a
start, and being entirely new was without precedent upon which to base any
such statement, but, as a matter of fact, the records of the lamp factory show
that in 1896 its daily output of lamps was actually about forty thousand.
The other instance referred to occurred shortly after the Edison Machine
Works was moved up to Schenectady, in 1886. One day, when he was at the
works, Edison sat down and wrote on a sheet of paper fifteen separate
predictions of the growth and future of the electrical business.
Notwithstanding the fact that the industry was then in an immature state,
and that the great boom did not set in until a few years afterward, twelve of
these predictions have been fully verified by the enormous growth and
development in all branches of the art.

What the explanation of this gift, power, or intuition may be, is perhaps
better left to the psychologist to speculate upon. If one were to ask Edison,
he would probably say, "Hard work, not too much sleep, and free use of the
imagination." Whether or not it would be possible for the average mortal to
arrive at such perfection of "guessing" by faithfully following this formula,
even reinforced by the Edison recipe for stimulating a slow imagination
with pastry, is open for demonstration.
Somewhat allied to this curious faculty is another no less remarkable, and
that is, the ability to point out instantly an error in a mass of reported
experimental results. While many instances could be definitely named, a
typical one, related by Mr. J. D. Flack, formerly master mechanic at the
lamp factory, may be quoted: "During the many years of lamp
experimentation, batches of lamps were sent to the photometer department
for test, and Edison would examine the tabulated test sheets. He ran over
every item of the tabulations rapidly, and, apparently without any
calculation whatever, would check off errors as fast as he came to them,
saying: 'You have made a mistake; try this one over.' In every case the
second test proved that he was right. This wonderful aptitude for infallibly
locating an error without an instant's hesitation for mental calculation, has
always appealed to me very forcibly."
The ability to detect errors quickly in a series of experiments is one of the
things that has enabled Edison to accomplish such a vast amount of work as
the records show. Examples of the minuteness of detail into which his
researches extend have already been mentioned, and as there are always a
number of such investigations in progress at the laboratory, this ability
stands Edison in good stead, for he is thus enabled to follow, and, if
necessary, correct each one step by step. In this he is aided by the great
powers of a mind that is able to free itself from absorbed concentration on
the details of one problem, and instantly to shift over and become deeply
and intelligently concentrated in another and entirely different one. For
instance, he may have been busy for hours on chemical experiments, and be
called upon suddenly to determine some mechanical questions. The
complete and easy transition is the constant wonder of his associates, for
there is no confusion of ideas resulting from these quick changes, no
hesitation or apparent effort, but a plunge into the midst of the new subject,
and an instant acquaintance with all its details, as if he had been studying it
for hours.
better left to the psychologist to speculate upon. If one were to ask Edison,
he would probably say, "Hard work, not too much sleep, and free use of the
imagination." Whether or not it would be possible for the average mortal to
arrive at such perfection of "guessing" by faithfully following this formula,
even reinforced by the Edison recipe for stimulating a slow imagination
with pastry, is open for demonstration.
Somewhat allied to this curious faculty is another no less remarkable, and
that is, the ability to point out instantly an error in a mass of reported
experimental results. While many instances could be definitely named, a
typical one, related by Mr. J. D. Flack, formerly master mechanic at the
lamp factory, may be quoted: "During the many years of lamp
experimentation, batches of lamps were sent to the photometer department
for test, and Edison would examine the tabulated test sheets. He ran over
every item of the tabulations rapidly, and, apparently without any
calculation whatever, would check off errors as fast as he came to them,
saying: 'You have made a mistake; try this one over.' In every case the
second test proved that he was right. This wonderful aptitude for infallibly
locating an error without an instant's hesitation for mental calculation, has
always appealed to me very forcibly."

A good stiff difficulty—one which may, perhaps, appear to be an
unsurmountable obstacle—only serves to make Edison cheerful, and brings
out variations of his methods in experimenting. Such an occurrence will
start him thinking, which soon gives rise to a line of suggestions for
approaching the trouble from various sides; or he will sit down and write
out a series of eliminations, additions, or changes to be worked out and
reported upon, with such variations as may suggest themselves during their
progress. It is at such times as these that his unfailing patience and
tremendous resourcefulness are in evidence. Ideas and expedients are
poured forth in a torrent, and although some of them have temporarily
appeared to the staff to be ridiculous or irrelevant, they have frequently
turned out to be the ones leading to a correct solution of the trouble.
Edison's inexhaustible resourcefulness and fertility of ideas have
contributed largely to his great success, and have ever been a cause of
amazement to those around him. Frequently, when it would seem to others
that the extreme end of an apparently blind alley had been reached, and that
it was impossible to proceed further, he has shown that there were several
ways out of it. Examples without number could be quoted, but one must
suffice by way of illustration. During the progress of the ore-milling work
at Edison, it became desirable to carry on a certain operation by some
special machinery. He requested the proper person on his engineering staff
to think this matter up and submit a few sketches of what he would propose
to do. He brought three drawings to Edison, who examined them and said
none of them would answer. The engineer remarked that it was too bad, for
there was no other way to do it. Mr. Edison turned to him quickly, and said:
"Do you mean to say that these drawings represent the only way to do this
work?" To which he received the reply: "I certainly do." Edison said
nothing. This happened on a Saturday. He followed his usual custom of
spending Sunday at home in Orange. When he returned to the works on
Monday morning, he took with him sketches he had made, showing
FORTY-EIGHT other ways of accomplishing the desired operation, and laid
them on the engineer's desk without a word. Subsequently one of these
ideas, with modifications suggested by some of the others, was put into
successful practice.
Difficulties seem to have a peculiar charm for Edison, whether they relate
to large or small things; and although the larger matters have contributed
most to the history of the arts, the same carefulness of thought has often

been the means of leading to improvements of permanent advantage even in
minor details. For instance, in the very earliest days of electric lighting, the
safe insulation of two bare wires fastened together was a serious problem
that was solved by him. An iron pot over a fire, some insulating material
melted therein, and narrow strips of linen drawn through it by means of a
wooden clamp, furnished a readily applied and adhesive insulation, which
was just as perfect for the purpose as the regular and now well-known
insulating tape, of which it was the forerunner.
Dubious results are not tolerated for a moment in Edison's experimental
work. Rather than pass upon an uncertainty, the experiment will be
dissected and checked minutely in order to obtain absolute knowledge, pro
and con. This searching method is followed not only in chemical or other
investigations, into which complexities might naturally enter, but also in
more mechanical questions, where simplicity of construction might
naturally seem to preclude possibilities of uncertainty. For instance, at the
time when he was making strenuous endeavors to obtain copper wire of
high conductivity, strict laboratory tests were made of samples sent by
manufacturers. One of these samples tested out poorer than a previous lot
furnished from the same factory. A report of this to Edison brought the
following note: "Perhaps the —— wire had a bad spot in it. Please cut it up
into lengths and test each one and send results to me immediately." Possibly
the electrical fraternity does not realize that this earnest work of Edison,
twenty-eight years ago, resulted in the establishment of the high quality of
copper wire that has been the recognized standard since that time. Says
Edison on this point: "I furnished the expert and apparatus to the Ansonia
Brass and Copper Company in 1883, and he is there yet. It was this expert
and this company who pioneered high-conductivity copper for the electrical
trade."
Nor is it generally appreciated in the industry that the adoption of what is
now regarded as a most obvious proposition—the high-economy
incandescent lamp—was the result of that characteristic foresight which
there has been occasion to mention frequently in the course of this
narrative, together with the courage and "horse-sense" which have always
been displayed by the inventor in his persistent pushing out with far-
reaching ideas, in the face of pessimistic opinions. As is well known, the
lamps of the first ten or twelve years of incandescent lighting were of low
economy, but had long life. Edison's study of the subject had led him to the
minor details. For instance, in the very earliest days of electric lighting, the

lamps of the first ten or twelve years of incandescent lighting were of low
economy, but had long life. Edison's study of the subject had led him to the
Page 415
conviction that the greatest growth of the electric-lighting industry would
be favored by a lamp taking less current, but having shorter, though
commercially economical life; and after gradually making improvements
along this line he developed, finally, a type of high-economy lamp which
would introduce a most radical change in existing conditions, and lead
ultimately to highly advantageous results. His start on this lamp, and an
expressed desire to have it manufactured for regular use, filled even some
of his business associates with dismay, for they could see nothing but
disaster ahead in forcing such a lamp on the market. His persistence and
profound conviction of the ultimate results were so strong and his
arguments so sound, however, that the campaign was entered upon.
Although it took two or three years to convince the public of the correctness
of his views, the idea gradually took strong root, and has now become an
integral principle of the business.
In this connection it may be noted that with remarkable prescience
Edison saw the coming of the modern lamps of to-day, which, by reason of
their small consumption of energy to produce a given candle-power, have
dismayed central-station managers. A few years ago a consumption of 3.1
watts per candle-power might safely be assumed as an excellent average,
and many stations fixed their rates and business on such a basis. The results
on income when the consumption, as in the new metallic-filament lamps,
drops to 1.25 watts per candle can readily be imagined. Edison has insisted
that central stations are selling light and not current; and he points to the
predicament now confronting them as truth of his assertion that when
selling light they share in all the benefits of improvement, but that when
they sell current the consumer gets all those benefits without division. The
dilemma is encountered by central stations in a bewildered way, as a novel
and unexpected experience; but Edison foresaw the situation and warned
against it long ago. It is one of the greatest gifts of statesmanship to see new
social problems years before they arise and solve them in advance. It is one
of the greatest attributes of invention to foresee and meet its own problems
in exactly the same way.

CHAPTER XXV
THE LABORATORY AT ORANGE AND THE STAFF
A LIVING interrogation-point and a born investigator from childhood,
Edison has never been without a laboratory of some kind for upward of half
a century.
In youthful years, as already described in this book, he became ardently
interested in chemistry, and even at the early age of twelve felt the necessity
for a special nook of his own, where he could satisfy his unconvinced mind
of the correctness or inaccuracy of statements and experiments contained in
the few technical books then at his command.
Ordinarily he was like other normal lads of his age—full of boyish,
hearty enjoyments—but withal possessed of an unquenchable spirit of
inquiry and an insatiable desire for knowledge. Being blessed with a wise
and discerning mother, his aspirations were encouraged; and he was
allowed a corner in her cellar. It is fair to offer tribute here to her bravery as
well as to her wisdom, for at times she was in mortal terror lest the
precocious experimenter below should, in his inexperience, make some
awful combination that would explode and bring down the house in ruins
on himself and the rest of the family.
Fortunately no such catastrophe happened, but young Edison worked
away in his embryonic laboratory, satisfying his soul and incidentally
depleting his limited pocket-money to the vanishing-point. It was, indeed,
owing to this latter circumstance that in a year or two his aspirations
necessitated an increase of revenue; and a consequent determination to earn
some money for himself led to his first real commercial enterprise as
"candy butcher" on the Grand Trunk Railroad, already mentioned in a
previous chapter. It has also been related how his precious laboratory was
transferred to the train; how he and it were subsequently expelled; and how
it was re-established in his home, where he continued studies and
experiments until the beginning of his career as a telegraph operator.

Page 417
The nomadic life of the next few years did not lessen his devotion to
study; but it stood seriously in the way of satisfying the ever-present
craving for a laboratory. The lack of such a place never prevented
experimentation, however, as long as he had a dollar in his pocket and some
available "hole in the wall." With the turning of the tide of fortune that
suddenly carried him, in New York in 1869, from poverty to the opulence of
$300 a month, he drew nearer to a realization of his cherished ambition in
having money, place, and some time (stolen from sleep) for more serious
experimenting. Thus matters continued until, at about the age of twenty-
two, Edison's inventions had brought him a relatively large sum of money,
and he became a very busy manufacturer, and lessee of a large shop in
Newark, New Jersey.
Now, for the first time since leaving that boyish laboratory in the old
home at Port Huron, Edison had a place of his own to work in, to think in;
but no one in any way acquainted with Newark as a swarming centre of
miscellaneous and multitudinous industries would recommend it as a
cloistered retreat for brooding reverie and introspection, favorable to
creative effort. Some people revel in surroundings of hustle and bustle, and
find therein no hindrance to great accomplishment. The electrical genius of
Newark is Edward Weston, who has thriven amid its turmoil and there has
developed his beautiful instruments of precision; just as Brush worked out
his arc-lighting system in Cleveland; or even as Faraday, surrounded by the
din and roar of London, laid the intellectual foundations of the whole
modern science of dynamic electricity. But Edison, though deaf, could not
make too hurried a retreat from Newark to Menlo Park, where, as if to
justify his change of base, vital inventions soon came thick and fast, year
after year. The story of Menlo has been told in another chapter, but the point
was not emphasized that Edison then, as later, tried hard to drop
manufacturing. He would infinitely rather be philosopher than producer; but
somehow the necessity of manufacturing is constantly thrust back upon him
by a profound—perhaps finical—sense of dissatisfaction with what other
people make for him. The world never saw a man more deeply and
desperately convinced that nothing in it approaches perfection. Edison is the
doctrine of evolution incarnate, applied to mechanics. As to the removal
from Newark, he may be allowed to tell his own story: "I had a shop at
Newark in which I manufactured stock tickers and such things. When I
moved to Menlo Park I took out only the machinery that would be
study; but it stood seriously in the way of satisfying the ever-present
craving for a laboratory. The lack of such a place never prevented
experimentation, however, as long as he had a dollar in his pocket and some

from Newark, he may be allowed to tell his own story: "I had a shop at
Newark in which I manufactured stock tickers and such things. When I
moved to Menlo Park I took out only the machinery that would be
Page 418
necessary for experimental purposes and left the manufacturing machinery
in the place. It consisted of many milling machines and other tools for
duplicating. I rented this to a man who had formerly been my bookkeeper,
and who thought he could make money out of manufacturing. There was
about $10,000 worth of machinery. He was to pay me $2000 a year for the
rent of the machinery and keep it in good order. After I moved to Menlo
Park, I was very busy with the telephone and phonograph, and I paid no
attention to this little arrangement. About three years afterward, it occurred
to me that I had not heard at all from the man who had rented this
machinery, so I thought I would go over to Newark and see how things
were going. When I got there, I found that instead of being a machine shop
it was a hotel! I have since been utterly unable to find out what became of
the man or the machinery." Such incidents tend to justify Edison in his
rather cynical remark that he has always been able to improve machinery
much quicker than men. All the way up he has had discouraging
experiences. "One day while I was carrying on my work in Newark, a Wall
Street broker came from the city and said he was tired of the 'Street,' and
wanted to go into something real. He said he had plenty of money. He
wanted some kind of a job to keep his mind off Wall Street. So we gave him
a job as a 'mucker' in chemical experiments. The second night he was there
he could not stand the long hours and fell asleep on a sofa. One of the boys
took a bottle of bromine and opened it under the sofa. It floated up and
produced a violent effect on the mucous membrane. The broker was taken
with such a fit of coughing he burst a blood-vessel, and the man who let the
bromine out got away and never came back. I suppose he thought there was
going to be a death. But the broker lived, and left the next day; and I have
never seen him since, either." Edison tells also of another foolhardy
laboratory trick of the same kind: "Some of my assistants in those days
were very green in the business, as I did not care whether they had had any
experience or not. I generally tried to turn them loose. One day I got a new
man, and told him to conduct a certain experiment. He got a quart of ether
and started to boil it over a naked flame. Of course it caught fire. The flame
was about four feet in diameter and eleven feet high. We had to call out the
fire department; and they came down and put a stream through the window.
That let all the fumes and chemicals out and overcame the firemen; and
there was the devil to pay. Another time we experimented with a tub full of
soapy water, and put hydrogen into it to make large bubbles. One of the

Page 419
boys, who was washing bottles in the place, had read in some book that
hydrogen was explosive, so he proceeded to blow the tub up. There was
about four inches of soap in the bottom of the tub, fourteen inches high; and
he filled it with soap bubbles up to the brim. Then he took a bamboo fish-
pole, put a piece of paper at the end, and touched it off. It blew every
window out of the place."
Always a shrewd, observant, and kindly critic of character, Edison tells
many anecdotes of the men who gathered around him in various capacities
at that quiet corner of New Jersey—Menlo Park—and later at Orange, in
the Llewellyn Park laboratory; and these serve to supplement the main
narrative by throwing vivid side-lights on the whole scene. Here, for
example, is a picture drawn by Edison of a laboratory interlude—just a bit
Rabelaisian: "When experimenting at Menlo Park we had all the way from
forty to fifty men. They worked all the time. Each man was allowed from
four to six hours' sleep. We had a man who kept tally, and when the time
came for one to sleep, he was notified. At midnight we had lunch brought in
and served at a long table at which the experimenters sat down. I also had
an organ which I procured from Hilbourne Roosevelt—uncle of the ex-
President—and we had a man play this organ while we ate our lunch.
During the summertime, after we had made something which was
successful, I used to engage a brick-sloop at Perth Amboy and take the
whole crowd down to the fishing-banks on the Atlantic for two days. On
one occasion we got outside Sandy Hook on the banks and anchored. A
breeze came up, the sea became rough, and a large number of the men were
sick. There was straw in the bottom of the boat, which we all slept on. Most
of the men adjourned to this straw very sick. Those who were not got a
piece of rancid salt pork from the skipper, and cut a large, thick slice out of
it. This was put on the end of a fish-hook and drawn across the men's faces.
The smell was terrific, and the effect added to the hilarity of the excursion.
"I went down once with my father and two assistants for a little fishing
inside Sandy Hook. For some reason or other the fishing was very poor. We
anchored, and I started in to fish. After fishing for several hours there was
not a single bite. The others wanted to pull up anchor, but I fished two days
and two nights without a bite, until they pulled up anchor and went away. I
would not give up. I was going to catch that fish if it took a week."
hydrogen was explosive, so he proceeded to blow the tub up. There was
about four inches of soap in the bottom of the tub, fourteen inches high; and
he filled it with soap bubbles up to the brim. Then he took a bamboo fish-
pole, put a piece of paper at the end, and touched it off. It blew every
window out of the place."
Always a shrewd, observant, and kindly critic of character, Edison tells
many anecdotes of the men who gathered around him in various capacities
at that quiet corner of New Jersey—Menlo Park—and later at Orange, in
the Llewellyn Park laboratory; and these serve to supplement the main
narrative by throwing vivid side-lights on the whole scene. Here, for
example, is a picture drawn by Edison of a laboratory interlude—just a bit
Rabelaisian: "When experimenting at Menlo Park we had all the way from
forty to fifty men. They worked all the time. Each man was allowed from
four to six hours' sleep. We had a man who kept tally, and when the time
came for one to sleep, he was notified. At midnight we had lunch brought in
and served at a long table at which the experimenters sat down. I also had
an organ which I procured from Hilbourne Roosevelt—uncle of the ex-
President—and we had a man play this organ while we ate our lunch.
During the summertime, after we had made something which was
successful, I used to engage a brick-sloop at Perth Amboy and take the
whole crowd down to the fishing-banks on the Atlantic for two days. On
one occasion we got outside Sandy Hook on the banks and anchored. A
breeze came up, the sea became rough, and a large number of the men were
sick. There was straw in the bottom of the boat, which we all slept on. Most
of the men adjourned to this straw very sick. Those who were not got a
piece of rancid salt pork from the skipper, and cut a large, thick slice out of
it. This was put on the end of a fish-hook and drawn across the men's faces.
The smell was terrific, and the effect added to the hilarity of the excursion.
"I went down once with my father and two assistants for a little fishing
inside Sandy Hook. For some reason or other the fishing was very poor. We
anchored, and I started in to fish. After fishing for several hours there was
not a single bite. The others wanted to pull up anchor, but I fished two days
and two nights without a bite, until they pulled up anchor and went away. I
would not give up. I was going to catch that fish if it took a week."

This is general. Let us quote one or two piquant personal observations of
a more specific nature as to the odd characters Edison drew around him in
his experimenting. "Down at Menlo Park a man came in one day and
wanted a job. He was a sailor. I hadn't any particular work to give him, but I
had a number of small induction coils, and to give him something to do I
told him to fix them up and sell them among his sailor friends. They were
fixed up, and he went over to New York and sold them all. He was an
extraordinary fellow. His name was Adams. One day I asked him how long
it was since he had been to sea, and he replied two or three years. I asked
him how he had made a living in the mean time, before he came to Menlo
Park. He said he made a pretty good living by going around to different
clinics and getting $10 at each clinic, because of having the worst case of
heart-disease on record. I told him if that was the case he would have to be
very careful around the laboratory. I had him there to help in experimenting,
and the heart-disease did not seem to bother him at all.
"It appeared that he had once been a slaver; and altogether he was a
tough character. Having no other man I could spare at that time, I sent him
over with my carbon transmitter telephone to exhibit it in England. It was
exhibited before the Post-Office authorities. Professor Hughes spent an
afternoon in examining the apparatus, and in about a month came out with
his microphone, which was absolutely nothing more nor less than my exact
invention. But no mention was made of the fact that, just previously, he had
seen the whole of my apparatus. Adams stayed over in Europe connected
with the telephone for several years, and finally died of too much whiskey
—but not of heart-disease. This shows how whiskey is the more dangerous
of the two.
"Adams said that at one time he was aboard a coffee-ship in the harbor of
Santos, Brazil. He fell down a hatchway and broke his arm. They took him
up to the hospital—a Portuguese one—where he could not speak the
language, and they did not understand English. They treated him for two
weeks for yellow fever! He was certainly the most profane man we ever had
around the laboratory. He stood high in his class."
And there were others of a different stripe. "We had a man with us at
Menlo called Segredor. He was a queer kind of fellow. The men got in the
habit of plaguing him; and, finally, one day he said to the assembled
experimenters in the top room of the laboratory: 'The next man that does it,

experimenters in the top room of the laboratory: 'The next man that does it,
Page 421
I will kill him.' They paid no attention to this, and next day one of them
made some sarcastic remark to him. Segredor made a start for his boarding-
house, and when they saw him coming back up the hill with a gun, they
knew there would be trouble, so they all made for the woods. One of the
men went back and mollified him. He returned to his work; but he was not
teased any more. At last, when I sent men out hunting for bamboo, I
dispatched Segredor to Cuba. He arrived in Havana on Tuesday, and on the
Friday following he was buried, having died of the black vomit. On the
receipt of the news of his death, half a dozen of the men wanted his job, but
my searcher in the Astor Library reported that the chances of finding the
right kind of bamboo for lamps in Cuba were very small; so I did not send a
substitute."
Another thumb-nail sketch made of one of his associates is this: "When
experimenting with vacuum-pumps to exhaust the incandescent lamps, I
required some very delicate and close manipulation of glass, and hired a
German glass-blower who was said to be the most expert man of his kind in
the United States. He was the only one who could make clinical
thermometers. He was the most extraordinarily conceited man I have ever
come across. His conceit was so enormous, life was made a burden to him
by all the boys around the laboratory. He once said that he was educated in
a university where all the students belonged to families of the aristocracy;
and the highest class in the university all wore little red caps. He said HE
wore one."
Of somewhat different caliber was "honest" John Kruesi, who first made
his mark at Menlo Park, and of whom Edison says: "One of the workmen I
had at Menlo Park was John Kruesi, who afterward became, from his
experience, engineer of the lighting station, and subsequently engineer of
the Edison General Electric Works at Schenectady. Kruesi was very exact in
his expressions. At the time we were promoting and putting up electric-light
stations in Pennsylvania, New York, and New England, there would be
delegations of different people who proposed to pay for these stations. They
would come to our office in New York, at '65,' to talk over the
specifications, the cost, and other things. At first, Mr. Kruesi was brought
in, but whenever a statement was made which he could not understand or
did not believe could be substantiated, he would blurt right out among these
prospects that he didn't believe it. Finally it disturbed these committees so
much, and raised so many doubts in their minds, that one of my chief
made some sarcastic remark to him. Segredor made a start for his boarding-
house, and when they saw him coming back up the hill with a gun, they
knew there would be trouble, so they all made for the woods. One of the

any longer. You are too painfully honest.' I said to him: 'We always tell the
truth. It may be deferred truth, but it is the truth.' He could not understand
that."
Various reasons conspired to cause the departure from Menlo Park
midway in the eighties. For Edison, in spite of the achievement with which
its name will forever be connected, it had lost all its attractions and all its
possibilities. It had been outgrown in many ways, and strange as the remark
may seem, it was not until he had left it behind and had settled in Orange,
New Jersey, that he can be said to have given definite shape to his life. He
was only forty in 1887, and all that he had done up to that time, tremendous
as much of it was, had worn a haphazard, Bohemian air, with all the
inconsequential freedom and crudeness somehow attaching to pioneer life.
The development of the new laboratory in West Orange, just at the foot of
Llewellyn Park, on the Orange Mountains, not only marked the happy
beginning of a period of perfect domestic and family life, but saw in the
planning and equipment of a model laboratory plant the consummation of
youthful dreams, and of the keen desire to enjoy resources adequate at any
moment to whatever strain the fierce fervor of research might put upon
them. Curiously enough, while hitherto Edison had sought to dissociate his
experimenting from his manufacturing, here he determined to develop a
large industry to which a thoroughly practical laboratory would be a central
feature, and ever a source of suggestion and inspiration. Edison's standpoint
to-day is that an evil to be dreaded in manufacture is that of over-
standardization, and that as soon as an article is perfect that is the time to
begin improving it. But he who would improve must experiment.
The Orange laboratory, as originally planned, consisted of a main
building two hundred and fifty feet long and three stories in height, together
with four other structures, each one hundred by twenty-five feet, and only
one story in height. All these were substantially built of brick. The main
building was divided into five chief divisions—the library, office, machine
shops, experimental and chemical rooms, and stock-room. The use of the
smaller buildings will be presently indicated.
Surrounding the whole was erected a high picket fence with a gate placed
on Valley Road. At this point a gate-house was provided and put in charge
of a keeper, for then, as at the present time, Edison was greatly sought after;

of a keeper, for then, as at the present time, Edison was greatly sought after;
Page 423
and, in order to accomplish any work at all, he was obliged to deny himself
to all but the most important callers. The keeper of the gate was usually
chosen with reference to his capacity for stony-hearted implacability and
adherence to instructions; and this choice was admirably made in one
instance when a new gateman, not yet thoroughly initiated, refused
admittance to Edison himself. It was of no use to try and explain. To the
gateman EVERY ONE was persona non grata without proper credentials,
and Edison had to wait outside until he could get some one to identify him.
On entering the main building the first doorway from the ample passage
leads the visitor into a handsome library finished throughout in yellow pine,
occupying the entire width of the building, and almost as broad as long. The
centre of this spacious room is an open rectangular space about forty by
twenty-five feet, rising clear about forty feet from the main floor to a
panelled ceiling. Around the sides of the room, bounding this open space,
run two tiers of gallery, divided, as is the main floor beneath them; into
alcoves of liberal dimensions. These alcoves are formed by racks extending
from floor to ceiling, fitted with shelves, except on two sides of both
galleries, where they are formed by a series of glass-fronted cabinets
containing extensive collections of curious and beautiful mineralogical and
geological specimens, among which is the notable Tiffany-Kunz collection
of minerals acquired by Edison some years ago. Here and there in these
cabinets may also be found a few models which he has used at times in his
studies of anatomy and physiology.
The shelves on the remainder of the upper gallery and part of those on
the first gallery are filled with countless thousands of specimens of ores and
minerals of every conceivable kind gathered from all parts of the world, and
all tagged and numbered. The remaining shelves of the first gallery are
filled with current numbers (and some back numbers) of the numerous
periodicals to which Edison subscribes. Here may be found the popular
magazines, together with those of a technical nature relating to electricity,
chemistry, engineering, mechanics, building, cement, building materials,
drugs, water and gas, power, automobiles, railroads, aeronautics,
philosophy, hygiene, physics, telegraphy, mining, metallurgy, metals, music,
and others; also theatrical weeklies, as well as the proceedings and
transactions of various learned and technical societies.

The first impression received as one enters on the main floor of the
library and looks around is that of noble proportions and symmetry as a
whole. The open central space of liberal dimensions and height, flanked by
the galleries and relieved by four handsome electric-lighting fixtures
suspended from the ceiling by long chains, conveys an idea of lofty
spaciousness; while the huge open fireplace, surmounted by a great clock
built into the wall, at one end of the room, the large rugs, the arm-chairs
scattered around, the tables and chairs in the alcoves, give a general air of
comfort combined with utility. In one of the larger alcoves, at the sunny end
of the main hall, is Edison's own desk, where he may usually be seen for a
while in the early morning hours looking over his mail or otherwise busily
working on matters requiring his attention.
At the opposite end of the room, not far from the open fireplace, is a long
table surrounded by swivel desk-chairs. It is here that directors' meetings
are sometimes held, and also where weighty matters are often discussed by
Edison at conference with his closer associates. It has been the privilege of
the writers to be present at some of these conferences, not only as
participants, but in some cases as lookers-on while awaiting their turn. On
such occasions an interesting opportunity is offered to study Edison in his
intense and constructive moods. Apparently oblivious to everything else, he
will listen with concentrated mind and close attention, and then pour forth a
perfect torrent of ideas and plans, and, if the occasion calls for it, will turn
around to the table, seize a writing-pad and make sketch after sketch with
lightning-like rapidity, tearing off each sheet as filled and tossing it aside to
the floor. It is an ordinary indication that there has been an interesting
meeting when the caretaker about fills a waste-basket with these discarded
sketches.
Directly opposite the main door is a beautiful marble statue purchased by
Edison at the Paris Exposition in 1889, on the occasion of his visit there.
The statue, mounted on a base three feet high, is an allegorical
representation of the supremacy of electric light over all other forms of
illumination, carried out by the life-size figure of a youth with half-spread
wings seated upon the ruins of a street gas-lamp, holding triumphantly high
above his head an electric incandescent lamp. Grouped about his feet are a
gear-wheel, voltaic pile, telegraph key, and telephone. This work of art was
executed by A. Bordiga, of Rome, held a prominent place in the department

devoted to Italian art at the Paris Exposition, and naturally appealed to
Edison as soon as he saw it.
In the middle distance, between the entrance door and this statue, has
long stood a magnificent palm, but at the present writing it has been set
aside to give place to a fine model of the first type of the Edison poured
cement house, which stands in a miniature artificial lawn upon a special
table prepared for it; while on the floor at the foot of the table are specimens
of the full-size molds in which the house will be cast.
The balustrades of the galleries and all other available places are filled
with portraits of great scientists and men of achievement, as well as with
pictures of historic and scientific interest. Over the fireplace hangs a large
photograph showing the Edison cement plant in its entire length, flanked on
one end of the mantel by a bust of Humboldt, and on the other by a statuette
of Sandow, the latter having been presented to Edison by the celebrated
athlete after the visit he made to Orange to pose for the motion pictures in
the earliest days of their development. On looking up under the second
gallery at this end is seen a great roll resting in sockets placed on each side
of the room. This is a huge screen or curtain which may be drawn down to
the floor to provide a means of projection for lantern slides or motion
pictures, for the entertainment or instruction of Edison and his guests. In
one of the larger alcoves is a large terrestrial globe pivoted in its special
stand, together with a relief map of the United States; and here and there are
handsomely mounted specimens of underground conductors and electric
welds that were made at the Edison Machine Works at Schenectady before
it was merged into the General Electric Company. On two pedestals stand,
respectively, two other mementoes of the works, one a fifteen-light dynamo
of the Edison type, and the other an elaborate electric fan—both of them
gifts from associates or employees.
In noting these various objects of interest one must not lose sight of the
fact that this part of the building is primarily a library, if indeed that fact did
not at once impress itself by a glance at the well-filled unglazed book-
shelves in the alcoves of the main floor. Here Edison's catholic taste in
reading becomes apparent as one scans the titles of thousands of volumes
ranged upon the shelves, for they include astronomy, botany, chemistry,
dynamics, electricity, engineering, forestry, geology, geography, mechanics,
mining, medicine, metallurgy, magnetism, philosophy, psychology, physics,

steam, steam-engines, telegraphy, telephony, and many others. Besides
these there are the journals and proceedings of numerous technical
societies; encyclopaedias of various kinds; bound series of important
technical magazines; a collection of United States and foreign patents,
embracing some hundreds of volumes, together with an extensive
assortment of miscellaneous books of special and general interest. There is
another big library up in the house on the hill—in fact, there are books upon
books all over the home. And wherever they are, those books are read.
As one is about to pass out of the library attention is arrested by an
incongruity in the form of a cot, which stands in an alcove near the door.
Here Edison, throwing himself down, sometimes seeks a short rest during
specially long working tours. Sleep is practically instantaneous and
profound, and he awakes in immediate and full possession of his faculties,
arising from the cot and going directly "back to the job" without a moment's
hesitation, just as a person wide awake would arise from a chair and
proceed to attend to something previously determined upon.
Immediately outside the library is the famous stock-room, about which
much has been written and invented. Its fame arose from the fact that
Edison planned it to be a repository of some quantity, great or small, of
every known and possibly useful substance not readily perishable, together
with the most complete assortment of chemicals and drugs that experience
and knowledge could suggest. Always strenuous in his experimentation, and
the living embodiment of the spirit of the song, I Want What I Want When I
Want It, Edison had known for years what it was to be obliged to wait, and
sometimes lack, for some substance or chemical that he thought necessary
to the success of an experiment. Naturally impatient at any delay which
interposed in his insistent and searching methods, and realizing the
necessity of maintaining the inspiration attending his work at any time, he
determined to have within his immediate reach the natural resources of the
world.
Hence it is not surprising to find the stock-room not only a museum, but
a sample-room of nature, as well as a supply department. To a casual visitor
the first view of this heterogeneous collection is quite bewildering, but on
more mature examination it resolves itself into a natural classification—as,
for instance, objects pertaining to various animals, birds, and fishes, such as
skins, hides, hair, fur, feathers, wool, quills, down, bristles, teeth, bones,
these there are the journals and proceedings of numerous technical
societies; encyclopaedias of various kinds; bound series of important
technical magazines; a collection of United States and foreign patents,
embracing some hundreds of volumes, together with an extensive
assortment of miscellaneous books of special and general interest. There is
another big library up in the house on the hill—in fact, there are books upon
books all over the home. And wherever they are, those books are read.
As one is about to pass out of the library attention is arrested by an
incongruity in the form of a cot, which stands in an alcove near the door.
Here Edison, throwing himself down, sometimes seeks a short rest during
specially long working tours. Sleep is practically instantaneous and
profound, and he awakes in immediate and full possession of his faculties,
arising from the cot and going directly "back to the job" without a moment's
hesitation, just as a person wide awake would arise from a chair and
proceed to attend to something previously determined upon.
Immediately outside the library is the famous stock-room, about which
much has been written and invented. Its fame arose from the fact that
Edison planned it to be a repository of some quantity, great or small, of
every known and possibly useful substance not readily perishable, together
with the most complete assortment of chemicals and drugs that experience
and knowledge could suggest. Always strenuous in his experimentation, and

hoofs, horns, tusks, shells; natural products, such as woods, barks, roots,
leaves, nuts, seeds, herbs, gums, grains, flours, meals, bran; also minerals in
great assortment; mineral and vegetable oils, clay, mica, ozokerite, etc. In
the line of textiles, cotton and silk threads in great variety, with woven
goods of all kinds from cheese-cloth to silk plush. As for paper, there is
everything in white and colored, from thinnest tissue up to the heaviest
asbestos, even a few newspapers being always on hand. Twines of all sizes,
inks, waxes, cork, tar, resin, pitch, turpentine, asphalt, plumbago, glass in
sheets and tubes; and a host of miscellaneous articles revealed on looking
around the shelves, as well as an interminable collection of chemicals,
including acids, alkalies, salts, reagents, every conceivable essential oil and
all the thinkable extracts. It may be remarked that this collection includes
the eighteen hundred or more fluorescent salts made by Edison during his
experimental search for the best material for a fluoroscope in the initial X-
ray period. All known metals in form of sheet, rod and tube, and of great
variety in thickness, are here found also, together with a most complete
assortment of tools and accessories for machine shop and laboratory work.
The list is confined to the merest general mention of the scope of this
remarkable and interesting collection, as specific details would stretch out
into a catalogue of no small proportions. When it is stated, however, that a
stock clerk is kept exceedingly busy all day answering the numerous and
various demands upon him, the reader will appreciate that this
comprehensive assortment is not merely a fad of Edison's, but stands rather
as a substantial tribute to his wide-angled view of possible requirements as
his various investigations take him far afield. It has no counterpart in the
world!
Beyond the stock-room, and occupying about half the building on the
same floor, lie a machine shop, engine-room, and boiler-room. This
machine shop is well equipped, and in it is constantly employed a large
force of mechanics whose time is occupied in constructing the heavier class
of models and mechanical devices called for by the varied experiments and
inventions always going on.
Immediately above, on the second floor, is found another machine shop
in which is maintained a corps of expert mechanics who are called upon to
do work of greater precision and fineness, in the construction of tools and
experimental models. This is the realm presided over lovingly by John F.

Ott, who has been Edison's designer of mechanical devices for over forty
years. He still continues to ply his craft with unabated skill and oversees the
work of the mechanics as his productions are wrought into concrete shape.
In one of the many experimental-rooms lining the sides of the second
floor may usually be seen his younger brother, Fred Ott, whose skill as a
dexterous manipulator and ingenious mechanic has found ample scope for
exercise during the thirty-two years of his service with Edison, not only at
the regular laboratories, but also at that connected with the inventor's winter
home in Florida. Still another of the Ott family, the son of John F., for some
years past has been on the experimental staff of the Orange laboratory.
Although possessing in no small degree the mechanical and manipulative
skill of the family, he has chosen chemistry as his special domain, and may
be found with the other chemists in one of the chemical-rooms.
On this same floor is the vacuum-pump room with a glass-blowers' room
adjoining, both of them historic by reason of the strenuous work done on
incandescent lamps and X-ray tubes within their walls. The tools and
appliances are kept intact, for Edison calls occasionally for their use in
some of his later experiments, and there is a suspicion among the laboratory
staff that some day he may resume work on incandescent lamps. Adjacent
to these rooms are several others devoted to physical and mechanical
experiments, together with a draughting-room.
Last to be mentioned, but the first in order as one leaves the head of the
stairs leading up to this floor, is No. 12, Edison's favorite room, where he
will frequently be found. Plain of aspect, being merely a space boarded off
with tongued-and-grooved planks—as all the other rooms are—without
ornament or floor covering, and containing only a few articles of cheap
furniture, this room seems to exercise a nameless charm for him. The door
is always open, and often he can be seen seated at a plain table in the centre
of the room, deeply intent on some of the numerous problems in which he is
interested. The table is usually pretty well filled with specimens or data of
experimental results which have been put there for his examination. At the
time of this writing these specimens consist largely of sections of positive
elements of the storage battery, together with many samples of nickel
hydrate, to which Edison devotes deep study. Close at hand is a microscope
which is in frequent use by him in these investigations. Around the room,
on shelves, are hundreds of bottles each containing a small quantity of
years. He still continues to ply his craft with unabated skill and oversees the
work of the mechanics as his productions are wrought into concrete shape.

Page 429
nickel hydrate made in as many different ways, each labelled
correspondingly. Always at hand will be found one or two of the laboratory
note-books, with frequent entries or comments in the handwriting which
once seen is never forgotten.
No. 12 is at times a chemical, a physical, or a mechanical room—
occasionally a combination of all, while sometimes it might be called a
consultation-room or clinic—for often Edison may be seen there in
animated conference with a group of his assistants; but its chief distinction
lies in its being one of his favorite haunts, and in the fact that within its
walls have been settled many of the perplexing problems and momentous
questions that have brought about great changes in electrical and
engineering arts during the twenty-odd years that have elapsed since the
Orange laboratory was built.
Passing now to the top floor the visitor finds himself at the head of a
broad hall running almost the entire length of the building, and lined mostly
with glass-fronted cabinets containing a multitude of experimental
incandescent lamps and an immense variety of models of phonographs,
motors, telegraph and telephone apparatus, meters, and a host of other
inventions upon which Edison's energies have at one time and another been
bent. Here also are other cabinets containing old papers and records, while
further along the wall are piled up boxes of historical models and
instruments. In fact, this hallway, with its conglomerate contents, may well
be considered a scientific attic. It is to be hoped that at no distant day these
Edisoniana will be assembled and arranged in a fireproof museum for the
benefit of posterity.
In the front end of the building, and extending over the library, is a large
room intended originally and used for a time as the phonograph music-hall
for record-making, but now used only as an experimental-room for
phonograph work, as the growth of the industry has necessitated a very
much larger and more central place where records can be made on a
commercial scale. Even the experimental work imposes no slight burden on
it. On each side of the hallway above mentioned, rooms are partitioned off
and used for experimental work of various kinds, mostly phonographic,
although on this floor are also located the storage-battery testing-room, a
chemical and physical room and Edison's private office, where all his
personal correspondence and business affairs are conducted by his personal
correspondingly. Always at hand will be found one or two of the laboratory
note-books, with frequent entries or comments in the handwriting which
once seen is never forgotten.

chemical and physical room and Edison's private office, where all his
personal correspondence and business affairs are conducted by his personal
Page 430
secretary, Mr. H. F. Miller. A visitor to this upper floor of the laboratory
building cannot but be impressed with a consciousness of the incessant
efforts that are being made to improve the reproducing qualities of the
phonograph, as he hears from all sides the sounds of vocal and instrumental
music constantly varying in volume and timbre, due to changes in the
experimental devices under trial.
The traditions of the laboratory include cots placed in many of the rooms
of these upper floors, but that was in the earlier years when the strenuous
scenes of Menlo Park were repeated in the new quarters. Edison and his
closest associates were accustomed to carry their labors far into the wee
sma' hours, and when physical nature demanded a respite from work, a
short rest would be obtained by going to bed on a cot. One would naturally
think that the wear and tear of this intense application, day after day and
night after night, would have tended to induce a heaviness and gravity of
demeanor in these busy men; but on the contrary, the old spirit of good-
humor and prankishness was ever present, as its frequent outbursts
manifested from time to time. One instance will serve as an illustration.
One morning, about 2.30, the late Charles Batchelor announced that he was
tired and would go to bed. Leaving Edison and the others busily working,
he went out and returned quietly in slippered feet, with his nightgown on,
the handle of a feather duster stuck down his back with the feathers waving
over his head, and his face marked. With unearthly howls and shrieks, a
l'Indien, he pranced about the room, incidentally giving Edison a scare that
made him jump up from his work. He saw the joke quickly, however, and
joined in the general merriment caused by this prank.
Leaving the main building with its corps of busy experimenters, and
coming out into the spacious yard, one notes the four long single-story brick
structures mentioned above. The one nearest the Valley Road is called the
galvanometer-room, and was originally intended by Edison to be used for
the most delicate and minute electrical measurements. In order to provide
rigid resting-places for the numerous and elaborate instruments he had
purchased for this purpose, the building was equipped along three-quarters
of its length with solid pillars, or tables, of brick set deep in the earth. These
were built up to a height of about two and a half feet, and each was
surmounted with a single heavy slab of black marble. A cement floor was
laid, and every precaution was taken to render the building free from all
magnetic influences, so that it would be suitable for electrical work of the

Page 431
utmost accuracy and precision. Hence, iron and steel were entirely
eliminated in its construction, copper being used for fixtures for steam and
water piping, and, indeed, for all other purposes where metal was
employed.
This room was for many years the headquarters of Edison's able assistant,
Dr. A. E. Kennelly, now professor of electrical engineering in Harvard
University to whose energetic and capable management were intrusted
many scientific investigations during his long sojourn at the laboratory.
Unfortunately, however, for the continued success of Edison's elaborate
plans, he had not been many years established in the laboratory before a
trolley road through West Orange was projected and built, the line passing
in front of the plant and within seventy-five feet of the galvanometer-room,
thus making it practically impossible to use it for the delicate purposes for
which it was originally intended.
For some time past it has been used for photography and some special
experiments on motion pictures as well as for demonstrations connected
with physical research; but some reminders of its old-time glory still remain
in evidence. In lofty and capacious glass-enclosed cabinets, in company
with numerous models of Edison's inventions, repose many of the costly
and elaborate instruments rendered useless by the ubiquitous trolley.
Instruments are all about, on walls, tables, and shelves, the photometer is
covered up; induction coils of various capacities, with other electrical
paraphernalia, lie around, almost as if the experimenter were absent for a
few days but would soon return and resume his work.
In numbering the group of buildings, the galvanometer-room is No. 1,
while the other single-story structures are numbered respectively 2, 3, and
4. On passing out of No. 1 and proceeding to the succeeding building is
noticed, between the two, a garage of ample dimensions and a smaller
structure, at the door of which stands a concrete-mixer. In this small
building Edison has made some of his most important experiments in the
process of working out his plans for the poured house. It is in this little
place that there was developed the remarkable mixture which is to play so
vital a part in the successful construction of these everlasting homes for
living millions.
Drawing near to building No. 2, olfactory evidence presents itself of the
immediate vicinity of a chemical laboratory. This is confirmed as one enters
eliminated in its construction, copper being used for fixtures for steam and
water piping, and, indeed, for all other purposes where metal was
employed.

Drawing near to building No. 2, olfactory evidence presents itself of the
immediate vicinity of a chemical laboratory. This is confirmed as one enters
Page 432
the door and finds that the entire building is devoted to chemistry. Long
rows of shelves and cabinets filled with chemicals line the room; a
profusion of retorts, alembics, filters, and other chemical apparatus on
numerous tables and stands, greet the eye, while a corps of experimenters
may be seen busy in the preparation of various combinations, some of
which are boiling or otherwise cooking under their dexterous manipulation.
It would not require many visits to discover that in this room, also,
Edison has a favorite nook. Down at the far end in a corner are a plain little
table and chair, and here he is often to be found deeply immersed in a study
of the many experiments that are being conducted. Not infrequently he is
actively engaged in the manipulation of some compound of special
intricacy, whose results might be illuminative of obscure facts not patent to
others than himself. Here, too, is a select little library of chemical literature.
The next building, No. 3, has a double mission—the farther half being
partitioned off for a pattern-making shop, while the other half is used as a
store-room for chemicals in quantity and for chemical apparatus and
utensils. A grimly humorous incident, as related by one of the laboratory
staff, attaches to No. 3. It seems that some time ago one of the helpers in the
chemical department, an excitable foreigner, became dissatisfied with his
wages, and after making an unsuccessful application for an increase, rushed
in desperation to Edison, and said "Eef I not get more money I go to take ze
cyanide potassia." Edison gave him one quick, searching glance and,
detecting a bluff, replied in an offhand manner: "There's a five-pound bottle
in No. 3," and turned to his work again. The foreigner did not go to get the
cyanide, but gave up his job.
The last of these original buildings, No. 4, was used for many years in
Edison's ore-concentrating experiments, and also for rough-and-ready
operations of other kinds, such as furnace work and the like. At the present
writing it is used as a general stock-room.
In the foregoing details, the reader has been afforded but a passing glance
at the great practical working equipment which constitutes the theatre of
Edison's activities, for, in taking a general view of such a unique and
comprehensive laboratory plant, its salient features only can be touched
upon to advantage. It would be but repetition to enumerate here the
practical results of the laboratory work during the past two decades, as they
appear on other pages of this work. Nor can one assume for a moment that
rows of shelves and cabinets filled with chemicals line the room; a
profusion of retorts, alembics, filters, and other chemical apparatus on
numerous tables and stands, greet the eye, while a corps of experimenters

Page 433
the history of Edison's laboratory is a closed book. On the contrary, its
territorial boundaries have been increasing step by step with the
enlargement of its labors, until now it has been obliged to go outside its
own proper domains to occupy some space in and about the great Edison
industrial buildings and space immediately adjacent. It must be borne in
mind that the laboratory is only the core of a group of buildings devoted to
production on a huge scale by hundreds of artisans.
Incidental mention has already been made of the laboratory at Edison's
winter residence in Florida, where he goes annually to spend a month or six
weeks. This is a miniature copy of the Orange laboratory, with its machine
shop, chemical-room, and general experimental department. While it is only
in use during his sojourn there, and carries no extensive corps of assistants,
the work done in it is not of a perfunctory nature, but is a continuation of
his regular activities, and serves to keep him in touch with the progress of
experiments at Orange, and enables him to give instructions for their
variation and continuance as their scope is expanded by his own
investigations made while enjoying what he calls "vacation." What Edison
in Florida speaks of as "loafing" would be for most of us extreme and
healthy activity in the cooler Far North.
A word or two may be devoted to the visitors received at the laboratory,
and to the correspondence. It might be injudicious to gauge the greatness of
a man by the number of his callers or his letters; but they are at least an
indication of the degree to which he interests the world. In both respects, for
these forty years, Edison has been a striking example of the manner in
which the sentiment of hero-worship can manifest itself, and of the deep
desire of curiosity to get satisfaction by personal observation or contact.
Edison's mail, like that of most well-known men, is extremely large, but
composed in no small degree of letters—thousands of them yearly—that
concern only the writers, and might well go to the waste-paper basket
without prolonged consideration. The serious and important part of the
mail, some personal and some business, occupies the attention of several
men; all such letters finding their way promptly into the proper channels,
often with a pithy endorsement by Edison scribbled on the margin. What to
do with a host of others it is often difficult to decide, even when written by
"cranks," who imagine themselves subject to strange electrical ailments
from which Edison alone can relieve them. Many people write asking his
opinion as to a certain invention, or offering him an interest in it if he will
territorial boundaries have been increasing step by step with the
enlargement of its labors, until now it has been obliged to go outside its
own proper domains to occupy some space in and about the great Edison
industrial buildings and space immediately adjacent. It must be borne in
mind that the laboratory is only the core of a group of buildings devoted to
production on a huge scale by hundreds of artisans.
Incidental mention has already been made of the laboratory at Edison's
winter residence in Florida, where he goes annually to spend a month or six
weeks. This is a miniature copy of the Orange laboratory, with its machine
shop, chemical-room, and general experimental department. While it is only
in use during his sojourn there, and carries no extensive corps of assistants,
the work done in it is not of a perfunctory nature, but is a continuation of
his regular activities, and serves to keep him in touch with the progress of
experiments at Orange, and enables him to give instructions for their
variation and continuance as their scope is expanded by his own
investigations made while enjoying what he calls "vacation." What Edison
in Florida speaks of as "loafing" would be for most of us extreme and
healthy activity in the cooler Far North.
A word or two may be devoted to the visitors received at the laboratory,
and to the correspondence. It might be injudicious to gauge the greatness of
a man by the number of his callers or his letters; but they are at least an
indication of the degree to which he interests the world. In both respects, for
these forty years, Edison has been a striking example of the manner in
which the sentiment of hero-worship can manifest itself, and of the deep
desire of curiosity to get satisfaction by personal observation or contact.
Edison's mail, like that of most well-known men, is extremely large, but
composed in no small degree of letters—thousands of them yearly—that
concern only the writers, and might well go to the waste-paper basket
without prolonged consideration. The serious and important part of the
mail, some personal and some business, occupies the attention of several
men; all such letters finding their way promptly into the proper channels,
often with a pithy endorsement by Edison scribbled on the margin. What to
do with a host of others it is often difficult to decide, even when written by
"cranks," who imagine themselves subject to strange electrical ailments
from which Edison alone can relieve them. Many people write asking his
opinion as to a certain invention, or offering him an interest in it if he will
Page 434
work it out. Other people abroad ask help in locating lost relatives; and
many want advice as to what they shall do with their sons, frequently
budding geniuses whose ability to wire a bell has demonstrated unusual
qualities. A great many persons want autographs, and some would like
photographs. The amazing thing about it all is that this flood of
miscellaneous letters flows on in one steady, uninterrupted stream, year in
and year out; always a curious psychological study in its variety and
volume; and ever a proof of the fact that once a man has become
established as a personality in the public eye and mind, nothing can stop the
tide of correspondence that will deluge him.
It is generally, in the nature of things, easier to write a letter than to make
a call; and the semi-retirement of Edison at a distance of an hour by train
from New York stands as a means of protection to him against those who
would certainly present their respects in person, if he could be got at
without trouble. But it may be seriously questioned whether in the
aggregate Edison's visitors are less numerous or less time-consuming than
his epistolary besiegers. It is the common experience of any visitor to the
laboratory that there are usually several persons ahead of him, no matter
what the hour of the day, and some whose business has been sufficiently
vital to get them inside the porter's gate, or even into the big library and
lounging-room. Celebrities of all kinds and distinguished foreigners are
numerous—princes, noblemen, ambassadors, artists, litterateurs, scientists,
financiers, women. A very large part of the visiting is done by scientific
bodies and societies; and then the whole place will be turned over to
hundreds of eager, well-dressed men and women, anxious to see everything
and to be photographed in the big courtyard around the central hero. Nor
are these groups and delegations limited to this country, for even large
parties of English, Dutch, Italian, or Japanese visitors come from time to
time, and are greeted with the same ready hospitality, although Edison, it is
easy to see, is torn between the conflicting emotions of a desire to be
courteous, and an anxiety to guard the precious hours of work, or watch the
critical stage of a new experiment.
One distinct group of visitors has always been constituted by the
"newspaper men." Hardly a day goes by that the journals do not contain
some reference to Edison's work or remarks; and the items are generally
based on an interview. The reporters are never away from the laboratory
very long; for if they have no actual mission of inquiry, there is always the

qualities. A great many persons want autographs, and some would like

very long; for if they have no actual mission of inquiry, there is always the
Page 435
chance of a good story being secured offhand; and the easy, inveterate
good-nature of Edison toward reporters is proverbial in the craft. Indeed, it
must be stated here that once in a while this confidence has been abused;
that stories have been published utterly without foundation; that interviews
have been printed which never took place; that articles with Edison's name
as author have been widely circulated, although he never saw them; and that
in such ways he has suffered directly. But such occasional incidents tend in
no wise to lessen Edison's warm admiration of the press or his readiness to
avail himself of it whenever a representative goes over to Orange to get the
truth or the real facts in regard to any matter of public importance. As for
the newspaper clippings containing such articles, or others in which
Edison's name appears—they are literally like sands of the sea-shore for
number; and the archives of the laboratory that preserve only a very minute
percentage of them are a further demonstration of what publicity means,
where a figure like Edison is concerned.

CHAPTER XXVI
EDISON IN COMMERCE AND MANUFACTURE
AN applicant for membership in the Engineers' Club of Philadelphia is
required to give a brief statement of the professional work he has done.
Some years ago a certain application was made, and contained the
following terse and modest sentence:
"I have designed a concentrating plant and built a machine shop, etc., etc.
THOMAS A. EDISON."
Although in the foregoing pages the reader has been made acquainted
with the tremendous import of the actualities lying behind those "etc., etc.,"
the narrative up to this point has revealed Edison chiefly in the light of
inventor, experimenter, and investigator. There have been some side
glimpses of the industries he has set on foot, and of their financial aspects,
and a later chapter will endeavor to sum up the intrinsic value of Edison's
work to the world. But there are some other interesting points that may be
touched on now in regard to a few of Edison's financial and commercial
ventures not generally known or appreciated.
It is a popular idea founded on experience that an inventor is not usually
a business man. One of the exceptions proving the rule may perhaps be met
in Edison, though all depends on the point of view. All his life he has had a
great deal to do with finance and commerce, and as one looks at the
magnitude of the vast industries he has helped to create, it would not be at
all unreasonable to expect him to be among the multi-millionaires. That he
is not is due to the absence of certain qualities, the lack of which Edison is
himself the first to admit. Those qualities may not be amiable, but great
wealth is hardly ever accumulated without them. If he had not been so
intent on inventing he would have made more of his great opportunities for
getting rich. If this utter detachment from any love of money for its own
sake has not already been illustrated in some of the incidents narrated, one
or two stories are available to emphasize the point. They do not involve any
want of the higher business acumen that goes to the proper conduct of
affairs. It was said of Gladstone that he was the greatest Chancellor of the

sake has not already been illustrated in some of the incidents narrated, one
or two stories are available to emphasize the point. They do not involve any
want of the higher business acumen that goes to the proper conduct of
affairs. It was said of Gladstone that he was the greatest Chancellor of the
Page 437
Exchequer England ever saw, but that as a retail merchant he would soon
have ruined himself by his bookkeeping.
Edison confesses that he has never made a cent out of his patents in
electric light and power—in fact, that they have been an expense to him,
and thus a free gift to the world. [18] This was true of the European patents
as well as the American. "I endeavored to sell my lighting patents in
different countries of Europe, and made a contract with a couple of men. On
account of their poor business capacity and lack of practicality, they
conveyed under the patents all rights to different corporations but in such a
way and with such confused wording of the contracts that I never got a cent.
One of the companies started was the German Edison, now the great
Allgemeine Elektricitaets Gesellschaft. The English company I never got
anything for, because a lawyer had originally advised Drexel, Morgan &
Co. as to the signing of a certain document, and said it was all right for me
to sign. I signed, and I never got a cent because there was a clause in it
which prevented me from ever getting anything." A certain easy-going
belief in human nature, and even a certain carelessness of attitude toward
business affairs, are here revealed. We have already pointed out two
instances where in his dealings with the Western Union Company he
stipulated that payments of $6000 per year for seventeen years were to be
made instead of $100,000 in cash, evidently forgetful of the fact that the
annual sum so received was nothing more than legal interest, which could
have been earned indefinitely if the capital had been only insisted upon. In
later life Edison has been more circumspect, but throughout his early career
he was constantly getting into some kind of scrape. Of one experience he
says:
[Footnote 18: Edison received some stock from the parent
lighting company, but as the capital stock of that company
was increased from time to time, his proportion grew
smaller, and he ultimately used it to obtain ready money
with which to create and finance the various "shops" in
which were manufactured the various items of electric-
lighting apparatus necessary to exploit his system. Besides,
he was obliged to raise additional large sums of money from
other sources for this purpose. He thus became a
manufacturer with capital raised by himself, and the stock
that he received later, on the formation of the General
Electric Company, was not for his electric-light patents,
but was in payment for his manufacturing establishments,
which had then grown to be of great commercial importance.]

"In the early days I was experimenting with metallic filaments for the
incandescent light, and sent a certain man out to California in search of
platinum. He found a considerable quantity in the sluice-boxes of the
Cherokee Valley Mining Company; but just then he found also that fruit-
gardening was the thing, and dropped the subject. He then came to me and
said that if he could raise $4000 he could go into some kind of orchard
arrangement out there, and would give me half the profits. I was unwilling
to do it, not having very much money just then, but his persistence was such
that I raised the money and gave it to him. He went back to California, and
got into mining claims and into fruit-growing, and became one of the
politicians of the Coast, and, I believe, was on the staff of the Governor of
the State. A couple of years ago he wounded his daughter and shot himself
because he had become ruined financially. I never heard from him after he
got the money."
Edison tells of another similar episode. "I had two men working for me—
one a German, the other a Jew. They wanted me to put up a little money and
start them in a shop in New York to make repairs, etc. I put up $800, and
was to get half of the profits, and each of them one-quarter. I never got
anything for it. A few years afterward I went to see them, and asked what
they were doing, and said I would like to sell my interest. They said: 'Sell
out what?' 'Why,' I said, 'my interest in the machinery.' They said: 'You don't
own this machinery. This is our machinery. You have no papers to show
anything. You had better get out.' I am inclined to think that the percentage
of crooked people was smaller when I was young. It has been steadily
rising, and has got up to a very respectable figure now. I hope it will never
reach par." To which lugubrious episode so provocative of cynicism, Edison
adds: "When I was a young fellow the first thing I did when I went to a
town was to put something into the savings-bank and start an account.
When I came to New York I put $30 into a savings-bank under the New
York Sun office. After the money had been in about two weeks the bank
busted. That was in 1870. In 1909 I got back $6.40, with a charge for $1.75
for law expenses. That shows the beauty of New York receiverships."
It is hardly to be wondered at that Edison is rather frank and unsparing in
some of his criticisms of shady modern business methods, and the mention
of the following incident always provokes him to a fine scorn. "I had an
interview with one of the wealthiest men in New York. He wanted me to
sell out my associates in the electric lighting business, and offered me all I
incandescent light, and sent a certain man out to California in search of
platinum. He found a considerable quantity in the sluice-boxes of the
Cherokee Valley Mining Company; but just then he found also that fruit-

of the following incident always provokes him to a fine scorn. "I had an
interview with one of the wealthiest men in New York. He wanted me to
sell out my associates in the electric lighting business, and offered me all I
Page 439
was going to get and $100,000 besides. Of course I would not do it. I found
out that the reason for this offer was that he had had trouble with Mr.
Morgan, and wanted to get even with him." Wall Street is, in fact, a frequent
object of rather sarcastic reference, applying even to its regular and
probably correct methods of banking. "When I was running my ore-mine,"
he says, "and got up to the point of making shipments to John Fritz, I didn't
have capital enough to carry the ore, so I went to J. P. Morgan & Co. and
said I wanted them to give me a letter to the City Bank. I wanted to raise
some money. I got a letter to Mr. Stillman; and went over and told him I
wanted to open an account and get some loans and discounts. He turned me
down, and would not do it. 'Well,' I said, 'isn't it banking to help a man in
this way?' He said: 'What you want is a partner.' I felt very much crestfallen.
I went over to a bank in Newark—the Merchants'—and told them what I
wanted. They said: 'Certainly, you can have the money.' I made my deposit,
and they pulled me through all right. My idea of Wall Street banking has
been very poor since that time. Merchant banking seems to be different."
As a general thing, Edison has had no trouble in raising money when he
needed it, the reason being that people have faith in him as soon as they
come to know him. A little incident bears on this point. "In operating the
Schenectady works Mr. Insull and I had a terrible burden. We had enormous
orders and little money, and had great difficulty to meet our payrolls and
buy supplies. At one time we had so many orders on hand we wanted
$200,000 worth of copper, and didn't have a cent to buy it. We went down
to the Ansonia Brass and Copper Company, and told Mr. Cowles just how
we stood. He said: 'I will see what I can do. Will you let my bookkeeper
look at your books?' We said: 'Come right up and look them over.' He sent
his man up and found we had the orders and were all right, although we
didn't have the money. He said: 'I will let you have the copper.' And for
years he trusted us for all the copper we wanted, even if we didn't have the
money to pay for it."
It is not generally known that Edison, in addition to being a newsboy and
a contributor to the technical press, has also been a backer and an "angel"
for various publications. This is perhaps the right place at which to refer to
the matter, as it belongs in the list of his financial or commercial
enterprises. Edison sums up this chapter of his life very pithily. "I was
interested, as a telegrapher, in journalism, and started the Telegraph Journal,
and got out about a dozen numbers when it was taken over by W. J.
out that the reason for this offer was that he had had trouble with Mr.
Morgan, and wanted to get even with him." Wall Street is, in fact, a frequent
object of rather sarcastic reference, applying even to its regular and
probably correct methods of banking. "When I was running my ore-mine,"
he says, "and got up to the point of making shipments to John Fritz, I didn't

enterprises. Edison sums up this chapter of his life very pithily. "I was
interested, as a telegrapher, in journalism, and started the Telegraph Journal,
and got out about a dozen numbers when it was taken over by W. J.
Page 440
Johnston, who afterward founded the Electrical World on it as an offshoot
from the Operator. I also started Science, and ran it for a year and a half. It
cost me too much money to maintain, and I sold it to Gardiner Hubbard, the
father-in-law of Alexander Graham Bell. He carried it along for years."
Both these papers are still in prosperous existence, particularly the
Electrical World, as the recognized exponent of electrical development in
America, where now the public spends as much annually for electricity as it
does for daily bread.
From all that has been said above it will be understood that Edison's real
and remarkable capacity for business does not lie in ability to "take care of
himself," nor in the direction of routine office practice, nor even in ordinary
administrative affairs. In short, he would and does regard it as a foolish
waste of his time to give attention to the mere occupancy of a desk.
His commercial strength manifests itself rather in the outlining of matters
relating to organization and broad policy with a sagacity arising from a
shrewd perception and appreciation of general business requirements and
conditions, to which should be added his intensely comprehensive grasp of
manufacturing possibilities and details, and an unceasing vigilance in
devising means of improving the quality of products and increasing the
economy of their manufacture.
Like other successful commanders, Edison also possesses the happy
faculty of choosing suitable lieutenants to carry out his policies and to
manage the industries he has created, such, for instance, as those with
which this chapter has to deal—namely, the phonograph, motion picture,
primary battery, and storage battery enterprises.
The Portland cement business has already been dealt with separately, and
although the above remarks are appropriate to it also, Edison being its head
and informing spirit, the following pages are intended to be devoted to
those industries that are grouped around the laboratory at Orange, and that
may be taken as typical of Edison's methods on the manufacturing side.
Within a few months after establishing himself at the present laboratory,
in 1887, Edison entered upon one of those intensely active periods of work
that have been so characteristic of his methods in commercializing his other
inventions. In this case his labors were directed toward improving the
phonograph so as to put it into thoroughly practicable form, capable of
ordinary use by the public at large. The net result of this work was the
from the Operator. I also started Science, and ran it for a year and a half. It
cost me too much money to maintain, and I sold it to Gardiner Hubbard, the
father-in-law of Alexander Graham Bell. He carried it along for years."
Both these papers are still in prosperous existence, particularly the
Electrical World, as the recognized exponent of electrical development in
America, where now the public spends as much annually for electricity as it
does for daily bread.

Like other successful commanders, Edison also possesses the happy
faculty of choosing suitable lieutenants to carry out his policies and to
manage the industries he has created, such, for instance, as those with
which this chapter has to deal—namely, the phonograph, motion picture,
primary battery, and storage battery enterprises.
The Portland cement business has already been dealt with separately, and
although the above remarks are appropriate to it also, Edison being its head
and informing spirit, the following pages are intended to be devoted to
those industries that are grouped around the laboratory at Orange, and that
may be taken as typical of Edison's methods on the manufacturing side.
Within a few months after establishing himself at the present laboratory,
in 1887, Edison entered upon one of those intensely active periods of work
that have been so characteristic of his methods in commercializing his other
inventions. In this case his labors were directed toward improving the
phonograph so as to put it into thoroughly practicable form, capable of
ordinary use by the public at large. The net result of this work was the
Page 441
general type of machine of which the well-known phonograph of today is a
refinement evolved through many years of sustained experiment and
improvement.
After a considerable period of strenuous activity in the eighties, the
phonograph and its wax records were developed to a sufficient degree of
perfection to warrant him in making arrangements for their manufacture
and commercial introduction. At this time the surroundings of the Orange
laboratory were distinctly rural in character. Immediately adjacent to the
main building and the four smaller structures, constituting the laboratory
plant, were grass meadows that stretched away for some considerable
distance in all directions, and at its back door, so to speak, ducks paddled
around and quacked in a pond undisturbed. Being now ready for
manufacturing, but requiring more facilities, Edison increased his real-
estate holdings by purchasing a large tract of land lying contiguous to what
he already owned. At one end of the newly acquired land two unpretentious
brick structures were erected, equipped with first-class machinery, and put
into commission as shops for manufacturing phonographs and their record
blanks; while the capacious hall forming the third story of the laboratory,
over the library, was fitted up and used as a music-room where records were
made.
Thus the modern Edison phonograph made its modest debut in 1888, in
what was then called the "Improved" form to distinguish it from the original
style of machine he invented in 1877, in which the record was made on a
sheet of tin-foil held in place upon a metallic cylinder. The "Improved"
form is the general type so well known for many years and sold at the
present day—viz., the spring or electric motor-driven machine with the
cylindrical wax record—in fact, the regulation Edison phonograph.
It did not take a long time to find a market for the products of the newly
established factory, for a world-wide public interest in the machine had
been created by the appearance of newspaper articles from time to time,
announcing the approaching completion by Edison of his improved
phonograph. The original (tin-foil) machine had been sufficient to illustrate
the fact that the human voice and other sounds could be recorded and
reproduced, but such a type of machine had sharp limitations in general use;
hence the coming into being of a type that any ordinary person could handle
was sufficient of itself to insure a market. Thus the demand for the new
refinement evolved through many years of sustained experiment and
improvement.

hence the coming into being of a type that any ordinary person could handle

Page 442
machines and wax records grew apace as the corporations organized to
handle the business extended their lines. An examination of the newspaper
files of the years 1888, 1889, and 1890 will reveal the great excitement
caused by the bringing out of the new phonograph, and how frequently and
successfully it was employed in public entertainments, either for the whole
or part of an evening. In this and other ways it became popularized to a still
further extent. This led to the demand for a nickel-in-the-slot machine,
which, when established, became immensely popular over the whole
country. In its earlier forms the "Improved" phonograph was not capable of
such general non-expert handling as is the machine of the present day, and
consequently there was a constant endeavor on Edison's part to simplify the
construction of the machine and its manner of operation. Experimentation
was incessantly going on with this in view, and in the processes of
evolution changes were made here and there that resulted in a still greater
measure of perfection.
In various ways there was a continual slow and steady growth of the
industry thus created, necessitating the erection of many additional
buildings as the years passed by. During part of the last decade there was a
lull, caused mostly from the failure of corporate interests to carry out their
contract relations with Edison, and he was thereby compelled to resort to
legal proceedings, at the end of which he bought in the outstanding
contracts and assumed command of the business personally.
Being thus freed from many irksome restrictions that had hung heavily
upon him, Edison now proceeded to push the phonograph business under a
broader policy than that which obtained under his previous contractual
relations. With the ever-increasing simplification and efficiency of the
machine and a broadening of its application, the results of this policy were
manifested in a still more rapid growth of the business that necessitated
further additions to the manufacturing plant. And thus matters went on until
the early part of the present decade, when the factory facilities were
becoming so rapidly outgrown as to render radical changes necessary. It
was in these circumstances that Edison's sagacity and breadth of business
capacity came to the front. With characteristic boldness and foresight he
planned the erection of the series of magnificent concrete buildings that
now stand adjacent to and around the laboratory, and in which the
manufacturing plant is at present housed.

There was no narrowness in his views in designing these buildings, but,
on the contrary, great faith in the future, for his plans included not only the
phonograph industry, but provided also for the coming development of
motion pictures and of the primary and storage battery enterprises.
In the aggregate there are twelve structures (including the administration
building), of which six are of imposing dimensions, running from 200 feet
long by 50 feet wide to 440 feet in length by 115 feet in width, all these
larger buildings, except one, being five stories in height. They are
constructed entirely of reinforced concrete with Edison cement, including
walls, floors, and stairways, thus eliminating fire hazard to the utmost
extent, and insuring a high degree of protection, cleanliness, and sanitation.
As fully three-fourths of the area of their exterior framework consists of
windows, an abundance of daylight is secured. These many advantages,
combined with lofty ceilings on every floor, provide ideal conditions for the
thousands of working people engaged in this immense plant.
In addition to these twelve concrete structures there are a few smaller
brick and wooden buildings on the grounds, in which some special
operations are conducted. These, however, are few in number, and at some
future time will be concentrated in one or more additional concrete
buildings. It will afford a clearer idea of the extent of the industries
clustered immediately around the laboratory when it is stated that the
combined floor space which is occupied by them in all these buildings is
equivalent in the aggregate to over fourteen acres.
It would be instructive, but scarcely within the scope of the narrative, to
conduct the reader through this extensive plant and see its many interesting
operations in detail. It must suffice, however, to note its complete and
ample equipment with modern machinery of every kind applicable to the
work; its numerous (and some of them wonderfully ingenious) methods,
processes, machines, and tools specially designed or invented for the
manufacture of special parts and supplemental appliances for the
phonograph or other Edison products; and also to note the interesting
variety of trades represented in the different departments, in which are
included chemists, electricians, electrical mechanicians, machinists,
mechanics, pattern-makers, carpenters, cabinet-makers, varnishers,
japanners, tool-makers, lapidaries, wax experts, photographic developers
and printers, opticians, electroplaters, furnacemen, and others, together with
on the contrary, great faith in the future, for his plans included not only the
phonograph industry, but provided also for the coming development of

Page 444
factory experimenters and a host of general employees, who by careful
training have become specialists and experts in numerous branches of these
industries.
Edison's plans for this manufacturing plant were sufficiently well
outlined to provide ample capacity for the natural growth of the business;
and although that capacity (so far as phonographs is concerned) has actually
reached an output of over 6000 complete phonographs PER WEEK, and
upward of 130,000 molded records PER DAY—with a pay-roll embracing
over 3500 employees, including office force—and amounting to about
$45,000 per week—the limits of production have not yet been reached.
The constant outpouring of products in such large quantities bespeaks the
unremitting activities of an extensive and busy selling organization to
provide for their marketing and distribution. This important department (the
National Phonograph Company), in all its branches, from president to
office-boy, includes about two hundred employees on its office pay-roll,
and makes its headquarters in the administration building, which is one of
the large concrete structures above referred to. The policy of the company is
to dispose of its wares through regular trade channels rather than to deal
direct with the public, trusting to local activity as stimulated by a liberal
policy of national advertising. Thus, there has been gradually built up a very
extensive business until at the present time an enormous output of
phonographs and records is distributed to retail customers in the United
States and Canada through the medium of about one hundred and fifty
jobbers and over thirteen thousand dealers. The Edison phonograph industry
thus organized is helped by frequent conventions of this large commercial
force.
Besides this, the National Phonograph Company maintains a special staff
for carrying on the business with foreign countries. While the aggregate
transactions of this department are not as extensive as those for the United
States and Canada, they are of considerable volume, as the foreign office
distributes in bulk a very large number of phonographs and records to
selling companies and agencies in Europe, Asia, Australia, Japan, and,
indeed, to all the countries of the civilized world. [19] Like England's
drumbeat, the voice of the Edison phonograph is heard around the world in
undying strains throughout the twenty-four hours.

some parts of the globe to which shipments of phonographs
and records are made:
Samoan Islands Falkland Islands Siam Corea Crete Island
Paraguay Chile Canary Islands Egypt British East Africa Cape
Colony Portuguese East Africa Liberia Java Straits

Indo-China Morocco Ecuador Brazil Madeira South Africa

In addition to the main manufacturing plant at Orange, another important
adjunct must not be forgotten, and that is, the Recording Department in
New York City, where the master records are made under the
superintendence of experts who have studied the intricacies of the art with
Edison himself. This department occupies an upper story in a lofty building,
and in its various rooms may be seen and heard many prominent musicians,
vocalists, speakers, and vaudeville artists studiously and busily engaged in
making the original records, which are afterward sent to Orange, and which,
if approved by the expert committee, are passed on to the proper department
for reproduction in large quantities.
When we consider the subject of motion pictures we find a similarity in
general business methods, for while the projecting machines and copies of
picture films are made in quantity at the Orange works (just as phonographs
and duplicate records are so made), the original picture, or film, like the
master record, is made elsewhere. There is this difference, however: that,
from the particular nature of the work, practically ALL master records are
made at one convenient place, while the essential interest in SOME motion
pictures lies in the fact that they are taken in various parts of the world,
often under exceptional circumstances. The "silent drama," however, calls
also for many representations which employ conventional acting, staging,
and the varied appliances of stagecraft. Hence, Edison saw early the
necessity of providing a place especially devised and arranged for the
production of dramatic performances in pantomime.
It is a far cry from the crude structure of early days—the "Black Maria"
of 1891, swung around on its pivot in the Orange laboratory yard—to the
well-appointed Edison theatres, or pantomime studios, in New York City.
The largest of these is located in the suburban Borough of the Bronx, and
consists of a three-story-and-basement building of reinforced concrete, in
which are the offices, dressing-rooms, wardrobe and property-rooms,
library and developing department. Contiguous to this building, and
connected with it, is the theatre proper, a large and lofty structure whose
and records are made:

connected with it, is the theatre proper, a large and lofty structure whose
Page 446
sides and roof are of glass, and whose floor space is sufficiently ample for
six different sets of scenery at one time, with plenty of room left for a
profusion of accessories, such as tables, chairs, pianos, bunch-lights,
search-lights, cameras, and a host of varied paraphernalia pertaining to
stage effects.
The second Edison theatre, or studio, is located not far from the shopping
district in New York City. In all essential features, except size and capacity,
it is a duplicate of the one in the Bronx, of which it is a supplement.
To a visitor coming on the floor of such a theatre for the first time there is
a sense of confusion in beholding the heterogeneous "sets" of scenery and
the motley assemblage of characters represented in the various plays in the
process of "taking," or rehearsal. While each set constitutes virtually a
separate stage, they are all on the same floor, without wings or proscenium-
arches, and separated only by a few feet. Thus, for instance, a Japanese
house interior may be seen cheek by jowl with an ordinary prison cell,
flanked by a mining-camp, which in turn stands next to a drawing-room set,
and in each a set of appropriate characters in pantomimic motion. The
action is incessant, for in any dramatic representation intended for the
motion-picture film every second counts.
The production of several completed plays per week necessitates the
employment of a considerable staff of people of miscellaneous trades and
abilities. At each of these two studios there is employed a number of stage-
directors, scene-painters, carpenters, property-men, photographers,
costumers, electricians, clerks, and general assistants, besides a capable
stock company of actors and actresses, whose generous numbers are
frequently augmented by the addition of a special star, or by a number of
extra performers, such as Rough Riders or other specialists. It may be,
occasionally, that the exigencies of the occasion require the work of a
performing horse, dog, or other animal. No matter what the object required
may be, whether animate or inanimate, if it is necessary for the play it is
found and pressed into service.
These two studios, while separated from the main plant, are under the
same general management, and their original negative films are forwarded
as made to the Orange works, where the large copying department is
located in one of the concrete buildings. Here, after the film has been
passed upon by a committee, a considerable number of positive copies are
six different sets of scenery at one time, with plenty of room left for a
profusion of accessories, such as tables, chairs, pianos, bunch-lights,
search-lights, cameras, and a host of varied paraphernalia pertaining to

Page 447
made by ingenious processes, and after each one is separately tested, or
"run off," in one or other of the three motion-picture theatres in the
building, they are shipped out to film exchanges in every part of the
country. How extensive this business has become may be appreciated when
it is stated that at the Orange plant there are produced at this time over eight
million feet of motion-picture film per year. And Edison's company is only
one of many producers.
Another of the industries at the Orange works is the manufacture of
projecting kinetoscopes, by means of which the motion pictures are shown.
While this of itself is also a business of considerable magnitude in its
aggregate yearly transactions, it calls for no special comment in regard to
commercial production, except to note that a corps of experimenters is
constantly employed refining and perfecting details of the machine. Its
basic features of operation as conceived by Edison remain unchanged.
On coming to consider the Edison battery enterprises, we must perforce
extend the territorial view to include a special chemical-manufacturing
plant, which is in reality a branch of the laboratory and the Orange works,
although actually situated about three miles away.
Both the primary and the storage battery employ certain chemical
products as essential parts of their elements, and indeed owe their very
existence to the peculiar preparation and quality of such products, as
exemplified by Edison's years of experimentation and research. Hence the
establishment of his own chemical works at Silver Lake, where, under his
personal supervision, the manufacture of these products is carried on in
charge of specially trained experts. At the present writing the plant covers
about seven acres of ground; but there is ample room for expansion, as
Edison, with wise forethought, secured over forty acres of land, so as to be
prepared for developments.
Not only is the Silver Lake works used for the manufacture of the
chemical substances employed in the batteries, but it is the plant at which
the Edison primary battery is wholly assembled and made up for
distribution to customers. This in itself is a business of no small magnitude,
having grown steadily on its merits year by year until it has now arrived at a
point where its sales run into the hundreds of thousands of cells per annum,
furnished largely to the steam railroads of the country for their signal
service.

Page 448
As to the storage battery, the plant at Silver Lake is responsible only for
the production of the chemical compounds, nickel-hydrate and iron oxide,
which enter into its construction. All the mechanical parts, the nickel
plating, the manufacture of nickel flake, the assembling and testing, are
carried on at the Orange works in two of the large concrete buildings above
referred to. A visit to this part of the plant reveals an amazing fertility of
resourcefulness and ingenuity in the devising of the special machines and
appliances employed in constructing the mechanical parts of these cells, for
it is practically impossible to fashion them by means of machinery and tools
to be found in the open market, notwithstanding the immense variety that
may be there obtained.
Since Edison completed his final series of investigations on his storage
battery and brought it to its present state of perfection, the commercial
values have increased by leaps and bounds. The battery, as it was originally
put out some years ago, made for itself an enviable reputation; but with its
improved form there has come a vast increase of business. Although the
largest of the concrete buildings where its manufacture is carried on is over
four hundred feet long and four stories in height, it has already become
necessary to plan extensions and enlargements of the plant in order to
provide for the production of batteries to fill the present demands. It was
not until the summer of 1909 that Edison was willing to pronounce the final
verdict of satisfaction with regard to this improved form of storage battery;
but subsequent commercial results have justified his judgment, and it is not
too much to predict that in all probability the business will assume gigantic
proportions within a very few years. At the present time (1910) the Edison
storage-battery enterprise is in its early stages of growth, and its status may
be compared with that of the electric-light system about the year 1881.
There is one more industry, though of comparatively small extent, that is
included in the activities of the Orange works, namely, the manufacture and
sale of the Bates numbering machine. This is a well-known article of
commerce, used in mercantile establishments for the stamping of
consecutive, duplicate, and manifold numbers on checks and other
documents. It is not an invention of Edison, but the organization owning it,
together with the patent rights, were acquired by him some years ago, and
he has since continued and enlarged the business both in scope and volume,
besides, of course, improving and perfecting the apparatus itself. These
machines are known everywhere throughout the country, and while the
the production of the chemical compounds, nickel-hydrate and iron oxide,
which enter into its construction. All the mechanical parts, the nickel
plating, the manufacture of nickel flake, the assembling and testing, are
carried on at the Orange works in two of the large concrete buildings above
referred to. A visit to this part of the plant reveals an amazing fertility of
resourcefulness and ingenuity in the devising of the special machines and
appliances employed in constructing the mechanical parts of these cells, for
it is practically impossible to fashion them by means of machinery and tools
to be found in the open market, notwithstanding the immense variety that
may be there obtained.
Since Edison completed his final series of investigations on his storage
battery and brought it to its present state of perfection, the commercial
values have increased by leaps and bounds. The battery, as it was originally
put out some years ago, made for itself an enviable reputation; but with its
improved form there has come a vast increase of business. Although the

annual sales are of comparatively moderate amount in comparison with the
totals of the other Edison industries at Orange, they represent in the
aggregate a comfortable and encouraging business.
In this brief outline review of the flourishing and extensive commercial
enterprises centred around the Orange laboratory, the facts, it is believed,
contain a complete refutation of the idea that an inventor cannot be a
business man. They also bear abundant evidence of the compatibility of
these two widely divergent gifts existing, even to a high degree, in the same
person. A striking example of the correctness of this proposition is afforded
in the present case, when it is borne in mind that these various industries
above described (whose annual sales run into many millions of dollars) owe
not only their very creation (except the Bates machine) and existence to
Edison's inventive originality and commercial initiative, but also their
continued growth and prosperity to his incessant activities in dealing with
their multifarious business problems. In publishing a portrait of Edison this
year, one of the popular magazines placed under it this caption: "Were the
Age called upon to pay Thomas A. Edison all it owes to him, the Age would
have to make an assignment." The present chapter will have thrown some
light on the idiosyncrasies of Edison as financier and as manufacturer, and
will have shown that while the claim thus suggested may be quite good, it
will certainly never be pressed or collected.

CHAPTER XXVII
THE VALUE OF EDISON'S INVENTIONS TO THE WORLD
IF the world were to take an account of stock, so to speak, and proceed in
orderly fashion to marshal its tangible assets in relation to dollars and cents,
the natural resources of our globe, from centre to circumference, would
head the list. Next would come inventors, whose value to the world as an
asset could be readily estimated from an increase of its wealth resulting
from the actual transformations of these resources into items of
convenience and comfort through the exercise of their inventive ingenuity.
Inventors of practical devices may be broadly divided into two classes—
first, those who may be said to have made two blades of grass grow where
only one grew before; and, second, great inventors, who have made grass
grow plentifully on hitherto unproductive ground. The vast majority of
practical inventors belong to and remain in the first of these divisions, but
there have been, and probably always will be, a less number who, by reason
of their greater achievements, are entitled to be included in both classes. Of
these latter, Thomas Alva Edison is one, but in the pages of history he
stands conspicuously pre-eminent—a commanding towering figure, even
among giants.
The activities of Edison have been of such great range, and his conquests
in the domains of practical arts so extensive and varied, that it is somewhat
difficult to estimate with any satisfactory degree of accuracy the money
value of his inventions to the world of to-day, even after making due
allowance for the work of other great inventors and the propulsive effect of
large amounts of capital thrown into the enterprises which took root, wholly
or in part, through the productions of his genius and energies. This
difficulty will be apparent, for instance, when we consider his telegraph and
telephone inventions. These were absorbed in enterprises already existing,
and were the means of assisting their rapid growth and expansion,
particularly the telephone industry. Again, in considering the fact that
Edison was one of the first in the field to design and perfect a practical and
operative electric railway, the main features of which are used in all electric

these latter, Thomas Alva Edison is one, but in the pages of history he
stands conspicuously pre-eminent—a commanding towering figure, even
among giants.
The activities of Edison have been of such great range, and his conquests
in the domains of practical arts so extensive and varied, that it is somewhat
difficult to estimate with any satisfactory degree of accuracy the money
value of his inventions to the world of to-day, even after making due
allowance for the work of other great inventors and the propulsive effect of
large amounts of capital thrown into the enterprises which took root, wholly
or in part, through the productions of his genius and energies. This
difficulty will be apparent, for instance, when we consider his telegraph and
telephone inventions. These were absorbed in enterprises already existing,
and were the means of assisting their rapid growth and expansion,
particularly the telephone industry. Again, in considering the fact that
Edison was one of the first in the field to design and perfect a practical and
operative electric railway, the main features of which are used in all electric
Page 452
roads of to-day, we are confronted with the problem as to what proportion
of their colossal investment and earnings should be ascribed to him.
Difficulties are multiplied when we pause for a moment to think of
Edison's influence on collateral branches of business. In the public mind he
is credited with the invention of the incandescent electric light, the
phonograph, and other widely known devices; but how few realize his
actual influence on other trades that are not generally thought of in
connection with these things. For instance, let us note what a prominent
engine builder, the late Gardiner C. Sims, has said: "Watt, Corliss, and
Porter brought forward steam-engines to a high state of proficiency, yet it
remained for Mr. Edison to force better proportions, workmanship, designs,
use of metals, regulation, the solving of the complex problems of high
speed and endurance, and the successful development of the shaft governor.
Mr. Edison is preeminent in the realm of engineering."
The phenomenal growth of the copper industry was due to a rapid and
ever-increasing demand, owing to the exploitation of the telephone, electric
light, electric motor, and electric railway industries. Without these there
might never have been the romance of "Coppers" and the rise and fall of
countless fortunes. And although one cannot estimate in definite figures the
extent of Edison's influence in the enormous increase of copper production,
it is to be remembered that his basic inventions constitute a most important
factor in the demand for the metal. Besides, one must also give him the
credit, as already noted, for having recognized the necessity for a pure
quality of copper for electric conductors, and for his persistence in having
compelled the manufacturers of that period to introduce new and additional
methods of refinement so as to bring about that result, which is now a sine
qua non.
Still considering his influence on other staples and collateral trades, let us
enumerate briefly and in a general manner some of the more important and
additional ones that have been not merely stimulated, but in many cases the
business and sales have been directly increased and new arts established
through the inventions of this one man—namely, iron, steel, brass, zinc,
nickel, platinum ($5 per ounce in 1878, now $26 an ounce), rubber, oils,
wax, bitumen, various chemical compounds, belting, boilers, injectors,
structural steel, iron tubing, glass, silk, cotton, porcelain, fine woods, slate,
of their colossal investment and earnings should be ascribed to him.

Page 453
marble, electrical measuring instruments, miscellaneous machinery, coal,
wire, paper, building materials, sapphires, and many others.
The question before us is, To what extent has Edison added to the wealth
of the world by his inventions and his energy and perseverance? It will be
noted from the foregoing that no categorical answer can be offered to such a
question, but sufficient material can be gathered from a statistical review of
the commercial arts directly influenced to afford an approximate idea of the
increase in national wealth that has been affected by or has come into being
through the practical application of his ideas.
First of all, as to inventions capable of fairly definite estimate, let us
mention the incandescent electric light and systems of distribution of
electric light, heat, and power, which may justly be considered as the
crowning inventions of Edison's life. Until October 21, 1879, there was
nothing in existence resembling our modern incandescent lamp. On that
date, as we have seen in a previous chapter, Edison's labors culminated in
his invention of a practical incandescent electric lamp embodying
absolutely all the essentials of the lamp of to-day, thus opening to the world
the doors of a new art and industry. To-day there are in the United States
more than 41,000,000 of these lamps, connected to existing central-station
circuits in active operation.
Such circuits necessarily imply the existence of central stations with their
equipment. Until the beginning of 1882 there were only a few arc-lighting
stations in existence for the limited distribution of current. At the present
time there are over 6000 central stations in this country for the distribution
of electric current for light, heat, and power, with capital obligations
amounting to not less than $1,000,000,000. Besides the above-named
41,000,000 incandescent lamps connected to their mains, there are about
500,000 arc lamps and 150,000 motors, using 750,000 horse-power, besides
countless fan motors and electric heating and cooking appliances.
When it is stated that the gross earnings of these central stations
approximate the sum of $225,000,000 yearly, the significant import of these
statistics of an art that came so largely from Edison's laboratory about thirty
years ago will undoubtedly be apparent.
But the above are not by any means all the facts relating to incandescent
electric lighting in the United States, for in addition to central stations there
are upward of 100,000 isolated or private plants in mills, factories,
wire, paper, building materials, sapphires, and many others.

But the above are not by any means all the facts relating to incandescent
electric lighting in the United States, for in addition to central stations there
are upward of 100,000 isolated or private plants in mills, factories,
Page 454
steamships, hotels, theatres, etc., owned by the persons or concerns who
operate them. These plants represent an approximate investment of
$500,000,000, and the connection of not less than 25,000,000 incandescent
lamps or their equivalent.
Then there are the factories where these incandescent lamps are made,
about forty in number, representing a total investment that may be
approximated at $25,000,000. It is true that many of these factories are
operated by other than the interests which came into control of the Edison
patents (General Electric Company), but the 150,000,000 incandescent
electric lamps now annually made are broadly covered in principle by
Edison's fundamental ideas and patents.
It will be noted that these figures are all in round numbers, but they are
believed to be well within the mark, being primarily founded upon the
special reports of the Census Bureau issued in 1902 and 1907, with the
natural increase from that time computed by experts who are in position to
obtain the facts. It would be manifestly impossible to give exact figures of
such a gigantic and swiftly moving industry, whose totals increase from
week to week.
The reader will naturally be disposed to ask whether it is intended to
claim that Edison has brought about all this magnificent growth of the
electric-lighting art. The answer to this is decidedly in the negative, for the
fact is that he laid some of the foundation and erected a building thereon,
and in the natural progressive order of things other inventors of more or less
fame have laid substructures or added a wing here and a story there until the
resultant great structure has attained such proportions as to evoke the
admiration of the beholder; but the old foundation and the fundamental
building still remain to support other parts. In other words, Edison created
the incandescent electric lamp, and invented certain broad and fundamental
systems of distribution of current, with all the essential devices of detail
necessary for successful operation. These formed a foundation. He also
spent great sums of money and devoted several years of patient labor in the
early practical exploitation of the dynamo and central station and isolated
plants, often under, adverse and depressing circumstances, with a dogged
determination that outlived an opposition steadily threatening defeat. These
efforts resulted in the firm commercial establishment of modern electric
lighting. It is true that many important inventions of others have a
operate them. These plants represent an approximate investment of
$500,000,000, and the connection of not less than 25,000,000 incandescent

Page 455
distinguished place in the art as it is exploited today, but the fact remains
that the broad essentials, such as the incandescent lamp, systems of
distribution, and some important details, are not only universally used, but
are as necessary to-day for successful commercial practice as they were
when Edison invented them many years ago.
The electric railway next claims our consideration, but we are
immediately confronted by a difficulty which seems insurmountable when
we attempt to formulate any definite estimate of the value and influence of
Edison's pioneer work and inventions. There is one incontrovertible fact—
namely, that he was the first man to devise, construct, and operate from a
central station a practicable, life-size electric railroad, which was capable of
transporting and did transport passengers and freight at variable speeds over
varying grades, and under complete control of the operator. These are the
essential elements in all electric railroading of the present day; but while
Edison's original broad ideas are embodied in present practice, the
perfection of the modern electric railway is greatly due to the labors and
inventions of a large number of other well-known inventors. There was no
reason why Edison could not have continued the commercial development
of the electric railway after he had helped to show its practicability in 1880,
1881, and 1882, just as he had completed his lighting system, had it not
been that his financial allies of the period lacked faith in the possibilities of
electric railroads, and therefore declined to furnish the money necessary for
the purpose of carrying on the work.
With these facts in mind, we shall ask the reader to assign to Edison a
due proportion of credit for his pioneer and basic work in relation to the
prodigious development of electric railroading that has since taken place.
The statistics of 1908 for American street and elevated railways show that
within twenty-five years the electric-railway industry has grown to embrace
38,812 miles of track on streets and for elevated railways, operated under
the ownership of 1238 separate companies, whose total capitalization
amounted to the enormous sum of $4,123,834,598. In the equipments
owned by such companies there are included 68,636 electric cars and
17,568 trailers and others, making a total of 86,204 of such vehicles. These
cars and equipments earned over $425,000,000 in 1907, in giving the public
transportation, at a cost, including transfers, of a little over three cents per
passenger, for whom a fifteen-mile ride would be possible. It is the cheapest
transportation in the world.
that the broad essentials, such as the incandescent lamp, systems of
distribution, and some important details, are not only universally used, but

when Edison invented them many years ago.

Some mention should also be made of the great electrical works of the
country, in which the dynamos, motors, and other varied paraphernalia are
made for electric lighting, electric railway, and other purposes. The largest
of these works is undoubtedly that of the General Electric Company at
Schenectady, New York, a continuation and enormous enlargement of the
shops which Edison established there in 1886. This plant at the present time
embraces over 275 acres, of which sixty acres are covered by fifty large and
over one hundred small buildings; besides which the company also owns
other large plants elsewhere, representing a total investment approximating
the sum of $34,850,000 up to 1908. The productions of the General Electric
Company alone average annual sales of nearly $75,000,000, but they do not
comprise the total of the country's manufactures in these lines.
Turning our attention now to the telephone, we again meet a condition
that calls for thoughtful consideration before we can properly appreciate
how much the growth of this industry owes to Edison's inventive genius. In
another place there has already been told the story of the telephone, from
which we have seen that to Alexander Graham Bell is due the broad idea of
transmission of speech by means of an electrical circuit; also that he
invented appropriate instruments and devices through which he
accomplished this result, although not to that extent which gave promise of
any great commercial practicability for the telephone as it then existed.
While the art was in this inefficient condition, Edison went to work on the
subject, and in due time, as we have already learned, invented and brought
out the carbon transmitter, which is universally acknowledged to have been
the needed device that gave to the telephone the element of commercial
practicability, and has since led to its phenomenally rapid adoption and
world-wide use. It matters not that others were working in the same
direction, Edison was legally adjudicated to have been the first to succeed
in point of time, and his inventions were put into actual use, and may be
found in principle in every one of the 7,000,000 telephones which are
estimated to be employed in the country at the present day. Basing the
statements upon facts shown by the Census reports of 1902 and 1907, and
adding thereto the growth of the industry since that time, we find on a
conservative estimate that at this writing the investment has been not less
than $800,000,000 in now existing telephone systems, while no fewer than
10,500,000,000 talks went over the lines during the year 1908. These
figures relate only to telephone systems, and do not include any details
country, in which the dynamos, motors, and other varied paraphernalia are
made for electric lighting, electric railway, and other purposes. The largest
of these works is undoubtedly that of the General Electric Company at

transmission of speech by means of an electrical circuit; also that he
invented appropriate instruments and devices through which he
accomplished this result, although not to that extent which gave promise of
any great commercial practicability for the telephone as it then existed.
While the art was in this inefficient condition, Edison went to work on the
subject, and in due time, as we have already learned, invented and brought
out the carbon transmitter, which is universally acknowledged to have been
the needed device that gave to the telephone the element of commercial
practicability, and has since led to its phenomenally rapid adoption and
world-wide use. It matters not that others were working in the same
direction, Edison was legally adjudicated to have been the first to succeed
in point of time, and his inventions were put into actual use, and may be
found in principle in every one of the 7,000,000 telephones which are
estimated to be employed in the country at the present day. Basing the
statements upon facts shown by the Census reports of 1902 and 1907, and
adding thereto the growth of the industry since that time, we find on a
conservative estimate that at this writing the investment has been not less
than $800,000,000 in now existing telephone systems, while no fewer than
10,500,000,000 talks went over the lines during the year 1908. These
figures relate only to telephone systems, and do not include any details
Page 457
regarding the great manufacturing establishments engaged in the
construction of telephone apparatus, of which there is a production
amounting to at least $15,000,000 per annum.
Leaving the telephone, let us now turn our attention to the telegraph, and
endeavor to show as best we can some idea of the measure to which it has
been affected by Edison's inventions. Although, as we have seen in a
previous part of this book, his earliest fame arose from his great practical
work in telegraphic inventions and improvements, there is no way in which
any definite computation can be made of the value of his contributions in
the art except, perhaps, in the case of his quadruplex, through which alone it
is estimated that there has been saved from $15,000,000 to $20,000,000 in
the cost of line construction in this country. If this were the only thing that
he had ever accomplished, it would entitle him to consideration as an
inventor of note. The quadruplex, however, has other material advantages,
but how far they and the natural growth of the business have contributed to
the investment and earnings of the telegraph companies, is beyond
practicable computation.
It would, perhaps, be interesting to speculate upon what might have been
the growth of the telegraph and the resultant benefit to the community had
Edison's automatic telegraph inventions been allowed to take their
legitimate place in the art, but we shall not allow ourselves to indulge in
flights of fancy, as the value of this chapter rests not upon conjecture, but
only upon actual fact. Nor shall we attempt to offer any statistics regarding
Edison's numerous inventions relating to telegraphs and kindred devices,
such as stock tickers, relays, magnets, rheotomes, repeaters, printing
telegraphs, messenger calls, etc., on which he was so busily occupied as an
inventor and manufacturer during the ten years that began with January,
1869. The principles of many of these devices are still used in the arts, but
have become so incorporated in other devices as to be inseparable, and
cannot now be dealt with separately. To show what they mean, however, it
might be noted that New York City alone has 3000 stock "tickers,"
consuming 50,000 miles of record tape every year.
Turning now to other important arts and industries which have been
created by Edison's inventions, and in which he is at this time taking an
active personal interest, let us visit Orange, New Jersey. When his present
laboratory was nearing completion in 1887, he wrote to Mr. J. Hood Wright,
construction of telephone apparatus, of which there is a production
amounting to at least $15,000,000 per annum.

laboratory was nearing completion in 1887, he wrote to Mr. J. Hood Wright,
Page 458
a partner in the firm of Drexel, Morgan & Co.: "My ambition is to build up
a great industrial works in the Orange Valley, starting in a small way and
gradually working up."
In this plant, which represents an investment approximating the sum of
$4,000,000, are grouped a number of industrial enterprises of which Edison
is either the sole or controlling owner and the guiding spirit. These
enterprises are the National Phonograph Company, the Edison Business
Phonograph Company, the Edison Phonograph Works, the Edison
Manufacturing Company, the Edison Storage Battery Company, and the
Bates Manufacturing Company. The importance of these industries will be
apparent when it is stated that at this plant the maximum pay-roll shows the
employment of over 4200 persons, with annual earnings in salaries and
wages of more than $2,750,000.
In considering the phonograph in its commercial aspect, and endeavoring
to arrive at some idea of the world's estimate of the value of this invention,
we feel the ground more firm under our feet, for Edison has in later years
controlled its manufacture and sale. It will be remembered that the
phonograph lay dormant, commercially speaking, for about ten years after it
came into being, and then later invention reduced it to a device capable of
more popular utility. A few years of rather unsatisfactory commercial
experience brought about a reorganization, through which Edison resumed
possession of the business. It has since been continued under his general
direction and ownership, and he has made a great many additional
inventions tending to improve the machine in all its parts.
The uses made of the phonograph up to this time have been of four kinds,
generally speaking—first, and principally, for amusement; second, for
instruction in languages; third, for business, in the dictation of
correspondence; and fourth, for sentimental reasons in preserving the voices
of friends. No separate figures are available to show the extent of its
employment in the second and fourth classes, as they are probably included
in machines coming under the first subdivision. Under this head we find
that there have been upward of 1,310,000 phonographs sold during the last
twenty years, with and for which there have been made and sold no fewer
than 97,845,000 records of a musical or other character. Phonographic
records are now being manufactured at Orange at the rate of 75,000 a day,
the annual sale of phonographs and records being approximately
a great industrial works in the Orange Valley, starting in a small way and
gradually working up."

the annual sale of phonographs and records being approximately
Page 459
$7,000,000, including business phonographs. This does not include blank
records, of which large numbers have also been supplied to the public.
The adoption of the business phonograph has not been characterized by
the unanimity that obtained in the case of the one used merely for
amusement, as its use involves some changes in methods that business men
are slow to adopt until they realize the resulting convenience and economy.
Although it is only a few years since the business phonograph has begun to
make some headway, it is not difficult to appreciate that Edison's prediction
in 1878 as to the value of such an appliance is being realized, when we find
that up to this time the sales run up to 12,695 in number. At the present time
the annual sales of the business phonographs and supplies, cylinders, etc.,
are not less than $350,000.
We must not forget that the basic patent of Edison on the phonograph has
long since expired, thus throwing open to the world the wonderful art of
reproducing human speech and other sounds. The world was not slow to
take advantage of the fact, hence there are in the field numerous other
concerns in the same business. It is conservatively estimated by those who
know the trade and are in position to form an opinion, that the figures above
given represent only about one-half of the entire business of the country in
phonographs, records, cylinders, and supplies.
Taking next his inventions that pertain to a more recently established but
rapidly expanding branch of business that provides for the amusement of
the public, popularly known as "motion pictures," we also find a general
recognition of value created. Referring the reader to a previous chapter for a
discussion of Edison's standing as a pioneer inventor in this art, let us
glance at the commercial proportions of this young but lusty business,
whose ramifications extend to all but the most remote and primitive hamlets
of our country.
The manufacture of the projecting machines and accessories, together
with the reproduction of films, is carried on at the Orange Valley plant, and
from the inception of the motion-picture business to the present time there
have been made upward of 16,000 projecting machines and many million
feet of films carrying small photographs of moving objects. Although the
motion-picture business, as a commercial enterprise, is still in its youth, it is
of sufficient moment to call for the annual production of thousands of
machines and many million feet of films in Edison's shops, having a sale
records, of which large numbers have also been supplied to the public.

Page 460
value of not less than $750,000. To produce the originals from which these
Edison films are made, there have been established two "studios," the
largest of which is in the Bronx, New York City.
In this, as well as in the phonograph business, there are many other
manufacturers in the field. Indeed, the annual product of the Edison
Manufacturing Company in this line is only a fractional part of the total that
is absorbed by the 8000 or more motion-picture theatres and exhibitions
that are in operation in the United States at the present time, and which
represent an investment of some $45,000,000. Licensees under Edison
patents in this country alone produce upward of 60,000,000 feet of films
annually, containing more than a billion and a half separate photographs. To
what extent the motion-picture business may grow in the not remote future
it is impossible to conjecture, for it has taken a place in the front rank of
rapidly increasing enterprises.
The manufacture and sale of the Edison-Lalande primary battery,
conducted by the Edison Manufacturing Company at the Orange Valley
plant, is a business of no mean importance. Beginning about twenty years
ago with a battery that, without polarizing, would furnish large currents
specially adapted for gas-engine ignition and other important purposes, the
business has steadily grown in magnitude until the present output amounts
to about 125,000 cells annually; the total number of cells put into the hands
of the public up to date being approximately 1,500,000. It will be readily
conceded that to most men this alone would be an enterprise of a lifetime,
and sufficient in itself to satisfy a moderate ambition. But, although it has
yielded a considerable profit to Edison and gives employment to many
people, it is only one of the many smaller enterprises that owe an existence
to his inventive ability and commercial activity.
So it also is in regard to the mimeograph, whose forerunner, the electric
pen, was born of Edison's brain in 1877. He had been long impressed by the
desirability of the rapid production of copies of written documents, and, as
we have seen by a previous chapter, he invented the electric pen for this
purpose, only to improve upon it later with a more desirable device which
he called the mimeograph, that is in use, in various forms, at this time.
Although the electric pen had a large sale and use in its time, the statistics
relating to it are not available. The mimeograph, however, is, and has been
for many years, a standard office appliance, and is entitled to consideration,
Edison films are made, there have been established two "studios," the
largest of which is in the Bronx, New York City.

Page 461
as the total number put into use up to this time is approximately 180,000,
valued at $3,500,000, while the annual output is in the neighborhood of
9000 machines, sold for about $150,000, besides the vast quantity of special
paper and supplies which its use entails in the production of the many
millions of facsimile letters and documents. The extent of production and
sale of supplies for the mimeograph may be appreciated when it is stated
that they bring annually an equivalent of three times the amount realized
from sales of machines. The manufacture and sale of the mimeograph does
not come within the enterprises conducted under Edison's personal
direction, as he sold out the whole thing some years ago to Mr. A. B. Dick,
of Chicago.
In making a somewhat radical change of subject, from duplicating
machines to cement, we find ourselves in a field in which Edison has made
a most decided impression. The reader has already learned that his entry
into this field was, in a manner, accidental, although logically in line with
pronounced convictions of many years' standing, and following up the fund
of knowledge gained in the magnetic ore-milling business. From being a
new-comer in the cement business, his corporation in five years has grown
to be the fifth largest producer in the United States, with a still increasing
capacity. From the inception of this business there has been a steady and
rapid development, resulting in the production of a grand total of over
7,300,000 barrels of cement up to the present date, having a value of about
$6,000,000, exclusive of package. At the time of this writing, the rate of
production is over 8000 barrels of cement per day, or, say, 2,500,000 barrels
per year, having an approximate selling value of a little less than
$2,000,000, with prospects of increasing in the near future to a daily output
of 10,000 barrels. This enterprise is carried on by a corporation called the
Edison Portland Cement Company, in which he is very largely interested,
and of which he is the active head and guiding spirit.
Had not Edison suspended the manufacture and sale of his storage battery
a few years ago because he was not satisfied with it, there might have been
given here some noteworthy figures of an extensive business, for the
company's books show an astonishing number of orders that were received
during the time of the shut-down. He was implored for batteries, but in spite
of the fact that good results had been obtained from the 18,000 or 20,000
cells sold some years ago, he adhered firmly to his determination to perfect
them to a still higher standard before resuming and continuing their
valued at $3,500,000, while the annual output is in the neighborhood of
9000 machines, sold for about $150,000, besides the vast quantity of special
paper and supplies which its use entails in the production of the many
millions of facsimile letters and documents. The extent of production and

manufacture as a regular commodity. As we have noted in a previous
chapter, however, deliveries of the perfected type were begun in the
summer of 1909, and since that time the business has continued to grow in
the measure indicated by the earlier experience.
Thus far we have concerned ourselves chiefly with those figures which
exhibit the extent of investment and production, but there is another and
humanly important side that presents itself for consideration namely, the
employment of a vast industrial army of men and women, who earn a living
through their connection with some of the arts and industries to which our
narrative has direct reference. To this the reader's attention will now be
drawn.
The following figures are based upon the Special Reports of the Census
Bureau, 1902 and 1907, with additions computed upon the increase that has
subsequently taken place. In the totals following is included the
compensation paid to salaried officials and clerks. Details relating to
telegraph systems are omitted.
Taking the electric light into consideration first, we find that in the
central stations of the United States there are not less than an average of
50,000 persons employed, requiring an aggregate yearly payroll of over
$40,000,000. This does not include the 100,000 or more isolated electric-
light plants scattered throughout the land. Many of these are quite large, and
at least one-third of them require one additional helper, thus adding, say,
33,000 employees to the number already mentioned. If we assume as low a
wage as $10 per week for each of these helpers, we must add to the
foregoing an additional sum of over $17,000,000 paid annually for wages,
almost entirely in the isolated incandescent electric lighting field.
Central stations and isolated plants consume over 100,000,000
incandescent electric lamps annually, and in the production of these there
are engaged about forty factories, on whose pay-rolls appear an average of
14,000 employees, earning an aggregate yearly sum of $8,000,000.
Following the incandescent lamp we must not forget an industry
exclusively arising from it and absolutely dependent upon it—namely, that
of making fixtures for such lamps, the manufacture of which gives
employment to upward of 6000 persons, who annually receive at least
$3,750,000 in compensation.

The detail devices of the incandescent electric lighting system also
contribute a large quota to the country's wealth in the millions of dollars
paid out in salaries and wages to many thousands of persons who are
engaged in their manufacture.
The electric railways of our country show even larger figures than the
lighting stations and plants, as they employ on the average over 250,000
persons, whose annual compensation amounts to not less than
$155,000,000.
In the manufacture of about $50,000,000 worth of dynamos and motors
annually, for central-station equipment, isolated plants, electric railways,
and other purposes, the manufacturers of the country employ an average of
not less than 30,000 people, whose yearly pay-roll amounts to no less a sum
than $20,000,000.
The growth of the telephone systems of the United States also furnishes
us with statistics of an analogous nature, for we find that the average
number of employees engaged in this industry is at least 140,000, whose
annual earnings aggregate a minimum of $75,000,000; besides which the
manufacturers of telephone apparatus employ over 12,000 persons, to
whom is paid annually about $5,500,000.
No attempt is made to include figures of collateral industries, such, for
instance, as copper, which is very closely allied with the electrical arts, and
the great bulk of which is refined electrically.
The 8000 or so motion-picture theatres of the country employ no fewer
than 40,000 people, whose aggregate annual income amounts to not less
than $37,000,000.
Coming now to the Orange Valley plant, we take a drop from these
figures to the comparatively modest ones which give us an average of 3600
employees and calling for an annual pay-roll of about $2,250,000. It must
be remembered, however, that the sums mentioned above represent
industries operated by great aggregations of capital, while the Orange
Valley plant, as well as the Edison Portland Cement Company, with an
average daily number of 530 employees and over $400,000 annual pay-roll,
represent in a large measure industries that are more in the nature of closely

contribute a large quota to the country's wealth in the millions of dollars
paid out in salaries and wages to many thousands of persons who are
engaged in their manufacture.
The electric railways of our country show even larger figures than the
lighting stations and plants, as they employ on the average over 250,000
persons, whose annual compensation amounts to not less than
$155,000,000.
In the manufacture of about $50,000,000 worth of dynamos and motors
annually, for central-station equipment, isolated plants, electric railways,
and other purposes, the manufacturers of the country employ an average of
not less than 30,000 people, whose yearly pay-roll amounts to no less a sum
than $20,000,000.
The growth of the telephone systems of the United States also furnishes
us with statistics of an analogous nature, for we find that the average
number of employees engaged in this industry is at least 140,000, whose
annual earnings aggregate a minimum of $75,000,000; besides which the
manufacturers of telephone apparatus employ over 12,000 persons, to
whom is paid annually about $5,500,000.
No attempt is made to include figures of collateral industries, such, for
instance, as copper, which is very closely allied with the electrical arts, and
the great bulk of which is refined electrically.
The 8000 or so motion-picture theatres of the country employ no fewer
than 40,000 people, whose aggregate annual income amounts to not less
than $37,000,000.
Coming now to the Orange Valley plant, we take a drop from these
figures to the comparatively modest ones which give us an average of 3600
employees and calling for an annual pay-roll of about $2,250,000. It must
be remembered, however, that the sums mentioned above represent
industries operated by great aggregations of capital, while the Orange
Valley plant, as well as the Edison Portland Cement Company, with an
average daily number of 530 employees and over $400,000 annual pay-roll,
represent in a large measure industries that are more in the nature of closely
held enterprises and practically under the direction of one mind.

been needed for the perfection of these arts; but it is equally true that, as
already noted, some of these industries are directly the creation of Edison,
while in every one of the rest his impress has been deep and significant.
Before he began inventing, only two of them were known at all as arts—
telegraphy and the manufacture of cement. Moreover, these figures deal
only with the United States, and take no account of the development of
many of the Edison inventions in Europe or of their adoption throughout the
world at large. Let it suffice

confuse the intellect until the function of analysis comes into play and leads
to more adequate apprehension.
So, in presenting the mass of statistics contained in this chapter, we fear
that the result may have been the bewilderment of the reader to some
extent. Nevertheless, in writing a biography of Edison, the main object is to
present the facts as they are, and leave it to the intelligent reader to classify,
apply, and analyze them in such manner as appeals most forcibly to his
intellectual processes. If in the foregoing pages there has appeared to be a
tendency to attribute to Edison the entire credit for the growth to which
many of the above-named great enterprises have in these latter days
attained, we must especially disclaim any intention of giving rise to such a
deduction. No one who has carefully followed the course of this narrative
can deny, however, that Edison is the father of some of the arts and
industries that have been mentioned, and that as to some of the others it was
the magic of his touch that helped make them practicable. Not only to his
work and ingenuity is due the present magnitude of these arts and
industries, but it is attributable also to the splendid work and numerous
contributions of other great inventors, such as Brush, Bell, Elihu Thomson,
Weston, Sprague, and many others, as well as to the financiers and investors
who in the past thirty years have furnished the vast sums of money that
were necessary to exploit and push forward these enterprises.
The reader may have noticed in a perusal of this chapter the lack of
autobiographical quotations, such as have appeared in other parts of this
narrative. Edison's modesty has allowed us but one remark on the subject.
This was made by him to one of the writers a short time ago, when, after an
interesting indulgence in reminiscences of old times and early inventions,
he leaned back in his chair, and with a broad smile on his face, said,

CHAPTER XXVIII
THE BLACK FLAG
THROUGHOUT the forty-odd years of his creative life, Edison has
realized by costly experience the truth of the cynical proverb that "A patent
is merely a title to a lawsuit." It is not intended, however, by this statement
to lead to any inference on the part of the reader that HE stands peculiarly
alone in any such experience, for it has been and still is the common lot of
every successful inventor, sooner or later.
To attribute dishonesty or cupidity as the root of the defence in all patent
litigation would be aiming very wide of the mark, for in no class of suits
that come before the courts are there any that present a greater variety of
complex, finely shaded questions, or that require more delicacy of
interpretation, than those that involve the construction of patents,
particularly those relating to electrical devices. Indeed, a careful study of
legal procedure of this character could not be carried far without discovery
of the fact that in numerous instances the differences of opinion between
litigants were marked by the utmost bona fides.
On the other hand, such study would reveal many cases of undoubted
fraudulent intent, as well as many bold attempts to deprive the inventor of
the fruits of his endeavors by those who have sought to evade, through
subtle technicalities of the law, the penalty justly due them for trickery,
evasion, or open contempt of the rights of others.
In the history of science and of the arts to which the world has owed its
continued progress from year to year there is disclosed one remarkable fact,
and that is, that whenever any important discovery or invention has been
made and announced by one man, it has almost always been disclosed later
that other men—possibly widely separated and knowing nothing of the
other's work—have been following up the same general lines of
investigation, independently, with the same object in mind. Their respective
methods might be dissimilar while tending to the same end, but it does not
necessarily follow that any one of these other experimenters might ever
have achieved the result aimed at, although, after the proclamation of

the fruits of his endeavors by those who have sought to evade, through
subtle technicalities of the law, the penalty justly due them for trickery,
evasion, or open contempt of the rights of others.
In the history of science and of the arts to which the world has owed its
continued progress from year to year there is disclosed one remarkable fact,
and that is, that whenever any important discovery or invention has been
made and announced by one man, it has almost always been disclosed later
that other men—possibly widely separated and knowing nothing of the
other's work—have been following up the same general lines of
investigation, independently, with the same object in mind. Their respective
methods might be dissimilar while tending to the same end, but it does not
necessarily follow that any one of these other experimenters might ever
have achieved the result aimed at, although, after the proclamation of
Page 467
success by one, it is easy to believe that each of the other independent
investigators might readily persuade himself that he would ultimately have
reached the goal in just that same way.
This peculiar coincidence of simultaneous but separate work not only
comes to light on the bringing out of great and important discoveries or
inventions, but becomes more apparent if a new art is disclosed, for then the
imagination of previous experimenters is stimulated through wide
dissemination of the tidings, sometimes resulting in more or less effort to
enter the newly opened field with devices or methods that resemble closely
the original and fundamental ones in principle and application. In this and
other ways there arises constantly in the United States Patent Office a large
number of contested cases, called "Interferences," where applications for
patents covering the invention of a similar device have been independently
filed by two or even more persons. In such cases only one patent can be
issued, and that to the inventor who on the taking of testimony shows
priority in date of invention. [20]
[Footnote 20: A most remarkable instance of contemporaneous
invention and without a parallel in the annals of the United
States Patent Office, occurred when, on the same day,
February 15, 1876, two separate descriptions were filed in
that office, one a complete application and the other a
caveat, but each covering an invention for "transmitting
vocal sounds telegraphically." The application was made by
Alexander Graham Bell, of Salem, Massachusetts, and the
caveat by Elisha Gray, of Chicago, Illinois. On examination
of the two papers it was found that both of them covered
practically the same ground, hence, as only one patent could
be granted, it became necessary to ascertain the precise
hour at which the documents were respectively filed, and put
the parties in interference. This was done, with the result
that the patent was ultimately awarded to Bell.]
In the opening up and development of any new art based upon a
fundamental discovery or invention, there ensues naturally an era of
supplemental or collateral inventive activity—the legitimate outcome of the
basic original ideas. Part of this development may be due to the inventive
skill and knowledge of the original inventor and his associates, who, by
reason of prior investigation, would be in better position to follow up the art
in its earliest details than others, who might be regarded as mere outsiders.
Thus a new enterprise may be presented before the world by its promoters
in the belief that they are strongly fortified by patent rights which will
protect them in a degree commensurate with the risks they have assumed.

Page 468
Supplemental inventions, however, in any art, new or old, are not limited
to those which emanate from the original workers, for the ingenuity of man,
influenced by the spirit of the times, seizes upon any novel line of action
and seeks to improve or enlarge upon it, or, at any rate, to produce more or
less variation of its phases. Consequently, there is a constant endeavor on
the part of a countless host of men possessing some degree of technical skill
and inventive ability, to win fame and money by entering into the already
opened fields of endeavor with devices and methods of their own, for which
subsidiary patents may be obtainable. Some of such patents may prove to be
valuable, while it is quite certain that in the natural order of things others
will be commercially worthless, but none may be entirely disregarded in the
history and development of the art.
It will be quite obvious, therefore, that the advent of any useful invention
or discovery, great or small, is followed by a clashing of many interests
which become complex in their interpretation by reason of the many
conflicting claims that cluster around the main principle. Nor is the
confusion less confounded through efforts made on the part of dishonest
persons, who, like vultures, follow closely on the trail of successful
inventors and (sometimes through information derived by underhand
methods) obtain patents on alleged inventions, closely approximating the
real ones, solely for the purpose of harassing the original patentee until they
are bought up, or else, with the intent of competing boldly in the new
business, trust in the delays of legal proceedings to obtain a sure foothold in
their questionable enterprise.
Then again there are still others who, having no patent rights, but waving
aside all compunction and in downright fraud, simply enter the commercial
field against the whole world, using ruthlessly whatever inventive skill and
knowledge the original patentee may have disclosed, and trusting to the
power of money, rapid movement, and mendacious advertising to build up a
business which shall presently assume such formidable proportions as to
force a compromise, or stave off an injunction until the patent has expired.
In nine cases out of ten such a course can be followed with relative
impunity; and guided by skilful experts who may suggest really trivial
changes here and there over the patented structure, and with the aid of keen
and able counsel, hardly a patent exists that could not be invaded by such
infringers. Such is the condition of our laws and practice that the patentee in
seeking to enforce his rights labors under a terrible handicap.

And, finally, in this recital of perplexing conditions confronting the
inventor, there must not be forgotten the commercial "shark," whose
predatory instincts are ever keenly alert for tender victims. In the wake of
every newly developed art of world-wide importance there is sure to follow
a number of unscrupulous adventurers, who hasten to take advantage of
general public ignorance of the true inwardness of affairs. Basing their
operations on this lack of knowledge, and upon the tendency of human
nature to give credence to widely advertised and high-sounding descriptions
and specious promises of vast profits, these men find little difficulty in
conjuring money out of the pockets of the unsophisticated and gullible, who
rush to become stockholders in concerns that have "airy nothings" for a
foundation, and that collapse quickly when the bubble is pricked. [21]
[Footnote 21: A notable instance of the fleecing of
unsuspecting and credulous persons occurred in the early
eighties, during the furor occasioned by the introduction of
Mr. Edison's electric-light system. A corporation claiming
to have a self-generating dynamo (practically perpetual
motion) advertised its preposterous claims extensively, and
actually succeeded in selling a large amount of stock,
which, of course, proved to be absolutely worthless.]
To one who is unacquainted with the trying circumstances attending the
introduction and marketing of patented devices, it might seem unnecessary
that an inventor and his business associates should be obliged to take into
account the unlawful or ostensible competition of pirates or schemers, who,
in the absence of legal decision, may run a free course for a long time.
Nevertheless, as public patronage is the element vitally requisite for
commercial success, and as the public is not usually in full possession of all
the facts and therefore cannot discriminate between the genuine and the
false, the legitimate inventor must avail himself of every possible means of
proclaiming and asserting his rights if he desires to derive any benefit from
the results of his skill and labor. Not only must he be prepared to fight in the
Patent Office and pursue a regular course of patent litigation against those
who may honestly deem themselves to be protected by other inventions or
patents of similar character, and also proceed against more palpable
infringers who are openly, defiantly, and illegitimately engaged in
competitive business operations, but he must, as well, endeavor to protect
himself against the assaults of impudent fraud by educating the public mind
to a point of intelligent apprehension of the true status of his invention and
the conflicting claims involved.

When the nature of a patent right is considered it is difficult to see why
this should be so. The inventor creates a new thing—an invention of utility
—and the people, represented by the Federal Government, say to him in
effect: "Disclose your invention to us in a patent so that we may know how
to practice it, and we will agree to give you a monopoly for seventeen
years, after which we shall be free to use it. If the right thus granted is
invaded, apply to a Federal Court and the infringer will be enjoined and
required to settle in damages." Fair and false promise! Is it generally
realized that no matter how flagrant the infringement nor how barefaced
and impudent the infringer, no Federal Court will grant an injunction
UNTIL THE PATENT SHALL HAVE BEEN FIRST LITIGATED TO
FINAL HEARING AND SUSTAINED? A procedure, it may be stated,
requiring years of time and thousands of dollars, during which other
infringers have generally entered the field, and all have grown fat.
Thus Edison and his business associates have been forced into a veritable
maelstrom of litigation during the major part of the last forty years, in the
effort to procure for themselves a small measure of protection for their
interests under the numerous inventions of note that he has made at various
times in that period. The earlier years of his inventive activity, while
productive of many important contributions to electrical industries, such as
stock tickers and printers, duplex, quadruplex, and automatic telegraphs,
were not marked by the turmoil of interminable legal conflicts that arose
after the beginning of the telephone and electric-light epochs. In fact, his
inventions; up to and including his telephone improvements (which entered
into already existing arts), had been mostly purchased by the Western Union
and other companies, and while there was more or less contesting of his
claims (especially in respect of the telephone), the extent of such litigation
was not so conspicuously great as that which centred subsequently around
his patents covering incandescent electric lighting and power systems.
Through these inventions there came into being an entirely new art,
complete in its practicability evolved by Edison after protracted
experiments founded upon most patient, thorough, and original methods of
investigation extending over several years. Long before attaining the goal,
he had realized with characteristic insight the underlying principles of the
great and comprehensive problem he had started out to solve, and plodded
steadily along the path that he had marked out, ignoring the almost
universal scientific disbelief in his ultimate success. "Dreamer," "fool,"
this should be so. The inventor creates a new thing—an invention of utility
—and the people, represented by the Federal Government, say to him in
effect: "Disclose your invention to us in a patent so that we may know how
to practice it, and we will agree to give you a monopoly for seventeen
years, after which we shall be free to use it. If the right thus granted is
invaded, apply to a Federal Court and the infringer will be enjoined and
required to settle in damages." Fair and false promise! Is it generally
realized that no matter how flagrant the infringement nor how barefaced
and impudent the infringer, no Federal Court will grant an injunction
UNTIL THE PATENT SHALL HAVE BEEN FIRST LITIGATED TO
FINAL HEARING AND SUSTAINED? A procedure, it may be stated,
requiring years of time and thousands of dollars, during which other
infringers have generally entered the field, and all have grown fat.
Thus Edison and his business associates have been forced into a veritable
maelstrom of litigation during the major part of the last forty years, in the
effort to procure for themselves a small measure of protection for their
interests under the numerous inventions of note that he has made at various
times in that period. The earlier years of his inventive activity, while
productive of many important contributions to electrical industries, such as
stock tickers and printers, duplex, quadruplex, and automatic telegraphs,

"boaster" were among the appellations bestowed upon him by unbelieving
critics. Ridicule was heaped upon him in the public prints, and mathematics
were called into service by learned men to settle the point forever that he
was attempting the utterly impossible.
But, presto! no sooner had he accomplished the task and shown concrete
results to the world than he found himself in the anomalous position of
being at once surrounded by the conditions which inevitably confront every
inventor. The path through the trackless forest had been blazed, and now
every one could find the way. At the end of the road was a rich prize
belonging rightfully to the man who had opened a way to it, but the
struggles of others to reach it by more or less honest methods now began
and continued for many years. If, as a former commissioner once said,
"Edison was the man who kept the path to the Patent Office hot with his
footsteps," there were other great inventors abreast or immediately on his
heels, some, to be sure, with legitimate, original methods and vital
improvements representing independent work; while there were also those
who did not trouble to invent, but simply helped themselves to whatever
ideas were available, and coming from any source.
Possibly events might have happened differently had Edison been able to
prevent the announcement of his electric-light inventions until he was
entirely prepared to bring out the system as a whole, ready for commercial
exploitation, but the news of his production of a practical and successful
incandescent lamp became known and spread like wild-fire to all corners of
the globe. It took more than a year after the evolution of the lamp for
Edison to get into position to do actual business, and during that time his
laboratory was the natural Mecca of every inquiring person. Small wonder,
then, that when he was prepared to market his invention he should find
others entering that market, at home and abroad, at the same time, and with
substantially similar merchandise.
Edison narrates two incidents that may be taken as characteristic of a
good deal that had to be contended with, coming in the shape of nefarious
attack. "In the early days of my electric light," he says, "curiosity and
interest brought a great many people to Menlo Park to see it. Some of them
did not come with the best of intentions. I remember the visit of one expert,
a well-known electrician, a graduate of Johns Hopkins University, and who
then represented a Baltimore gas company. We had the lamps exhibited in a

a well-known electrician, a graduate of Johns Hopkins University, and who
then represented a Baltimore gas company. We had the lamps exhibited in a
Page 472
large room, and so arranged on a table as to illustrate the regular layout of
circuits for houses and streets. Sixty of the men employed at the laboratory
were used as watchers, each to keep an eye on a certain section of the
exhibit, and see there was no monkeying with it. This man had a length of
insulated No. 10 wire passing through his sleeves and around his back, so
that his hands would conceal the ends and no one would know he had it.
His idea, of course, was to put this wire across the ends of the supplying
circuits, and short-circuit the whole thing—put it all out of business without
being detected. Then he could report how easily the electric light went out,
and a false impression would be conveyed to the public. He did not know
that we had already worked out the safety-fuse, and that every group of
lights was thus protected independently. He put this jumper slyly in contact
with the wires—and just four lamps went out on the section he tampered
with. The watchers saw him do it, however, and got hold of him and just led
him out of the place with language that made the recording angels jump for
their typewriters."
The other incident is as follows: "Soon after I had got out the
incandescent light I had an interference in the Patent Office with a man
from Wisconsin. He filed an application for a patent and entered into a
conspiracy to 'swear back' of the date of my invention, so as to deprive me
of it. Detectives were put on the case, and we found he was a 'faker,' and we
took means to break the thing up. Eugene Lewis, of Eaton & Lewis, had
this in hand for me. Several years later this same man attempted to defraud
a leading firm of manufacturing chemists in New York, and was sent to
State prison. A short time after that a syndicate took up a man named
Goebel and tried to do the same thing, but again our detective-work was too
much for them. This was along the same line as the attempt of Drawbaugh
to deprive Bell of his telephone. Whenever an invention of large
prospective value comes out, these cases always occur. The lamp patent was
sustained in the New York Federal Court. I thought that was final and would
end the matter, but another Federal judge out in St. Louis did not sustain it.
The result is I have never enjoyed any benefits from my lamp patents,
although I fought for many years." The Goebel case will be referred to later
in this chapter.
The original owner of the patents and inventions covering his electric-

in this chapter.
The original owner of the patents and inventions covering his electric-
lighting system, the Edison Electric Light Company (in which Edison was
largely interested as a stockholder), thus found at the outset that its
Page 473
commercial position was imperilled by the activity of competitors who had
sprung up like mushrooms. It became necessary to take proper preliminary
legal steps to protect the interests which had been acquired at the cost of so
much money and such incessant toil and experiment. During the first few
years in which the business of the introduction of the light was carried on
with such strenuous and concentrated effort, the attention of Edison and his
original associates was constantly focused upon the commercial
exploitation and the further development of the system at home and abroad.
The difficult and perplexing situation at that time is thus described by Major
S. B. Eaton:
"The reason for the delay in beginning and pushing suits for
infringements of the lamp patent has never been generally understood. In
my official position as president of the Edison Electric Light Company I
became the target, along with Mr. Edison, for censure from the stockholders
and others on account of this delay, and I well remember how deep the
feeling was. In view of the facts that a final injunction on the lamp patent
was not obtained until the life of the patent was near its end, and, next, that
no damages in money were ever paid by the guilty infringers, it has been
generally believed that Mr. Edison sacrificed the interest of his stockholders
selfishly when he delayed the prosecution of patent suits and gave all his
time and energies to manufacturing. This belief was the stronger because
the manufacturing enterprises belonged personally to Mr. Edison and not to
his company. But the facts render it easy to dispel this false belief. The
Edison inventions were not only a lamp; they comprised also an entire
system of central stations. Such a thing was new to the world, and the
apparatus, as well as the manufacture thereof, was equally new. Boilers,
engines, dynamos, motors, distribution mains, meters, house-wiring, safety-
devices, lamps, and lamp-fixtures—all were vital parts of the whole system.
Most of them were utterly novel and unknown to the arts, and all of them
required quick, and, I may say, revolutionary thought and invention. The
firm of Babcock & Wilcox gave aid on the boilers, Armington & Sims
undertook the engines, but everything else was abnormal. No factories in
the land would take up the manufacture. I remember, for instance, our
interviews with Messrs. Mitchell, Vance & Co., the leading manufacturers
of house gas-lighting fixtures, such as brackets and chandeliers. They had
no faith in electric lighting, and rejected all our overtures to induce them to
take up the new business of making electric-light fixtures. As regards other

Page 474
parts of the Edison system, notably the Edison dynamo, no such machines
had ever existed; there was no factory in the world equipped to make them,
and, most discouraging of all, the very scientific principles of their
construction were still vague and experimental.
"What was to be done? Mr. Edison has never been greater than when he
met and solved this crisis. 'If there are no factories,' he said, 'to make my
inventions, I will build the factories myself. Since capital is timid, I will
raise and supply it. The issue is factories or death.' Mr. Edison invited the
cooperation of his leading stockholders. They lacked confidence or did not
care to increase their investments. He was forced to go on alone. The chain
of Edison shops was then created. By far the most perplexing of these new
manufacturing problems was the lamp. Not only was it a new industry, one
without shadow of prototype, but the mechanical devices for making the
lamps, and to some extent the very machines to make those devices, were to
be invented. All of this was done by the courage, capital, and invincible
energy and genius of the great inventor. But Mr. Edison could not create
these great and diverse industries and at the same time give requisite
attention to litigation. He could not start and develop the new and hard
business of electric lighting and yet spare one hour to pursue infringers.
One thing or the other must wait. All agreed that it must be the litigation.
And right there a lasting blow was given to the prestige of the Edison
patents. The delay was translated as meaning lack of confidence; and the
alert infringer grew strong in courage and capital. Moreover, and what was
the heaviest blow of all, he had time, thus unmolested, to get a good start.
"In looking back on those days and scrutinizing them through the years, I
am impressed by the greatness, the solitary greatness I may say, of Mr.
Edison. We all felt then that we were of importance, and that our
contribution of effort and zeal were vital. I can see now, however, that the
best of us was nothing but the fly on the wheel. Suppose anything had
happened to Edison? All would have been chaos and ruin.. To him,
therefore, be the glory, if not the profit."
The foregoing remarks of Major Eaton show authoritatively how the
much-discussed delay in litigating the Edison patents was so greatly
misunderstood at the time, and also how imperatively necessary it was for
Edison and his associates to devote their entire time and energies to the
commercial development of the art. As the lighting business increased,
had ever existed; there was no factory in the world equipped to make them,
and, most discouraging of all, the very scientific principles of their
construction were still vague and experimental.

much-discussed delay in litigating the Edison patents was so greatly
misunderstood at the time, and also how imperatively necessary it was for
Edison and his associates to devote their entire time and energies to the
commercial development of the art. As the lighting business increased,
Page 475
however, and a great number of additional men were initiated into its
mysteries, Edison and his experts were able to spare some time to legal
matters, and an era of active patent litigation against infringers was opened
about the year 1885 by the Edison company, and thereafter continued for
many years.
While the history of this vast array of legal proceedings possesses a
fascinating interest for those involved, as well as for professional men, legal
and scientific, it could not be expected that it would excite any such feeling
on the part of a casual reader. Hence, it is not proposed to encumber this
narrative with any detailed record of the numerous suits that were brought
and conducted through their complicated ramifications by eminent counsel.
Suffice it to say that within about sixteen years after the commencement of
active patent litigation, there had been spent by the owners of the Edison
lighting patents upward of two million dollars in prosecuting more than two
hundred lawsuits brought against persons who were infringing many of the
patents of Edison on the incandescent electric lamp and component parts of
his system. Over fifty separate patents were involved in these suits,
including the basic one on the lamp (ordinarily called the "Filament"
patent), other detail lamp patents, as well as those on sockets, switches,
dynamos, motors, and distributing systems.
The principal, or "test," suit on the "Filament" patent was that brought
against "The United States Electric Lighting Company," which became a
cause celebre in the annals of American jurisprudence. Edison's claims were
strenuously and stubbornly contested throughout a series of intense legal
conflicts that raged in the courts for a great many years. Both sides of the
controversy were represented by legal talent of the highest order, under
whose examination and cross-examination volumes of testimony were
taken, until the printed record (including exhibits) amounted to more than
six thousand pages. Scientific and technical literature and records in all
parts of the civilized world were subjected to the most minute scrutiny of
opposing experts in the endeavor to prove Edison to be merely an adapter of
methods and devices already projected or suggested by others. The world
was ransacked for anything that might be claimed as an anticipation of what
he had done. Every conceivable phase of ingenuity that could be devised by
technical experts was exercised in the attempt to show that Edison had
accomplished nothing new. Everything that legal acumen could suggest—
every subtle technicality of the law—all the complicated variations of
mysteries, Edison and his experts were able to spare some time to legal
matters, and an era of active patent litigation against infringers was opened
about the year 1885 by the Edison company, and thereafter continued for
many years.

Page 476
phraseology that the novel nomenclature of a young art would allow—all
were pressed into service and availed of by the contestors of the Edison
invention in their desperate effort to defeat his claims. It was all in vain,
however, for the decision of the court was in favor of Edison, and his lamp
patent was sustained not only by the tribunal of the first resort, but also by
the Appellate Court some time afterward.
The first trial was had before Judge Wallace in the United States Circuit
Court for the Southern District of New York, and the appeal was heard by
Judges Lacombe and Shipman, of the United States Circuit Court of
Appeals. Before both tribunals the cause had been fully represented by
counsel chosen from among the most eminent representatives of the bar at
that time, those representing the Edison interests being the late Clarence A.
Seward and Grosvenor P. Lowrey, together with Sherburne Blake Eaton,
Albert H. Walker, and Richard N. Dyer. The presentation of the case to the
courts had in both instances been marked by masterly and able arguments,
elucidated by experiments and demonstrations to educate the judges on
technical points. Some appreciation of the magnitude of this case may be
gained from the fact that the argument on its first trial employed a great
many days, and the minutes covered hundreds of pages of closely
typewritten matter, while the argument on appeal required eight days, and
was set forth in eight hundred and fifty pages of typewriting. Eliminating all
purely forensic eloquence and exparte statements, the addresses of counsel
in this celebrated suit are worthy of deep study by an earnest student, for,
taken together, they comprise the most concise, authentic, and complete
history of the prior state of the art and the development of the incandescent
lamp that had been made up to that time. [22]
[Footnote 22: The argument on appeal was conducted with the dignity
and decorum that characterize such a proceeding in that
court. There is usually little that savors of humor in the
ordinary conduct of a case of this kind, but in the present
instance a pertinent story was related by Mr. Lowrey, and it
is now reproduced. In the course of his address to the
court, Mr. Lowrey said:
"I have to mention the name of one expert whose testimony
will, I believe, be found as accurate, as sincere, as
straightforward as if it were the preaching of the gospel. I
do it with great pleasure, and I ask you to read the
testimony of Charles L. Clarke along with that of Thomas A.

University of Ghent, pursued a series of investigations into
the capacity of various animals to receive ideas. Among the
rest he put a pickerel into a tank containing water, and
separated across its middle by a transparent glass plate,
and on the other side he put a red roach. Now your Honors
both know how a pickerel loves a red roach, and I have no
doubt you will remember that he is a fish of a very low
forehead and an unlimited appetite. When this pickerel saw
the red roach through the glass, he made one of those awful
dashes which is usually the ruin of whatever stands in its
way; but he didn't reach the red roach. He received an
impression, doubtless. It was not sufficient, however, to
discourage him, and he immediately tried again, and he
continued to try for three-quarters of an hour. At the end
of three-quarters of an hour he seemed a little shaken and
discouraged, and stopped, and the red roach was taken out
for that day and the pickerel left. On the succeeding day
the red roach was restored, and the pickerel had forgotten
the impressions of the first day, and he repeated this
again. At the end of the second day the roach was taken out.
This was continued, not through so long a period as the
effort to take my friend Clarke and devour him, but for a
period of about three weeks. At the end of the three weeks,
the time during which the pickerel persisted each day had
been shortened and shortened, until it was at last
discovered that he didn't try at all. The plate glass was
then removed, and the pickerel and the red roach sailed
around together in perfect peace ever afterward. The
pickerel doubtless attributed to the roach all this shaking,
the rebuff which he had received. And that is about the
condition in which my brother Duncan and my friend Clarke
were at the end of this examination."
Mr. Duncan—"I notice on the redirect that Mr. Clarke
changed his color."
Mr. Lowrey—"Well, perhaps he was a different kind of a
roach then; but you didn't succeed in taking him.
"I beg your Honors to read the testimony of Mr. Clarke in
the light of the anecdote of the pickerel and the roach."
others, he has not yet become expert; what he may descend to
later cannot be known; he entered upon his first experience,
I think, with my brother Duncan, who is no trifler when he
comes to deal with these questions, and for several months
Mr. Clarke was pursued up and down, over a range of
suggestions of what he would have thought if he had thought
something else had been said at some time when something
else was not said."
Mr. Duncan—"I got three pages a day out of him, too."
Mr. Lowrey—"Well, it was a good result. It always recalled
to me what I venture now, since my friend breaks in upon me
in this rude manner, to tell the court as well illustrative
of what happened there. It is the story of the pickerel and
the roach. My friend, Professor Von Reisenberg, of the

Owing to long-protracted delays incident to the taking of testimony and
preparation for trial, the argument before the United States Circuit Court of
Appeals was not had until the late spring of 1892, and its decision in favor
of the Edison Lamp patent was filed on October 4, 1892, MORE THAN
TWELVE YEARS AFTER THE ISSUANCE OF THE PATENT ITSELF.
As the term of the patent had been limited under the law, because certain
foreign patents had been issued to Edison before that in this country, there
was now but a short time left for enjoyment of the exclusive rights
contemplated by the statute and granted to Edison and his assigns by the
terms of the patent itself. A vigorous and aggressive legal campaign was
therefore inaugurated by the Edison Electric Light Company against the
numerous infringing companies and individuals that had sprung up while
the main suit was pending. Old suits were revived and new ones instituted.
Injunctions were obtained against many old offenders, and it seemed as
though the Edison interests were about to come into their own for the brief
unexpired term of the fundamental patent, when a new bombshell was
dropped into the Edison camp in the shape of an alleged anticipation of the
invention forty years previously by one Henry Goebel. Thus, in 1893, the
litigation was reopened, and a protracted series of stubbornly contested
conflicts was fought in the courts.
Goebel's claims were not unknown to the Edison Company, for as far
back as 1882 they had been officially brought to its notice coupled with an
offer of sale for a few thousand dollars. A very brief examination into their
merits, however, sufficed to demonstrate most emphatically that Goebel had
never made a practical incandescent lamp, nor had he ever contributed a
single idea or device bearing, remotely or directly, on the development of
the art. Edison and his company, therefore, rejected the offer
unconditionally and declined to enter into any arrangements whatever with
Goebel. During the prosecution of the suits in 1893 it transpired that the
Goebel claims had also been investigated by the counsel of the defendant
company in the principal litigation already related, but although every
conceivable defence and anticipation had been dragged into the case during
the many years of its progress, the alleged Goebel anticipation was not even
touched upon therein. From this fact it is quite apparent that they placed no
credence on its bona fides.

But desperate cases call for desperate remedies. Some of the infringing
lamp-manufacturing concerns, which during the long litigation had grown
strong and lusty, and thus far had not been enjoined by the court, now saw
injunctions staring them in the face, and in desperation set up the Goebel
so-called anticipation as a defence in the suits brought against them.
This German watchmaker, Goebel, located in the East Side of New York
City, had undoubtedly been interested, in a desultory kind of way, in simple
physical phenomena, and a few trifling experiments made by him some
forty or forty-five years previously were magnified and distorted into
brilliant and all-comprehensive discoveries and inventions. Avalanches of
affidavits of himself, "his sisters and his cousins and his aunts," practically
all persons in ordinary walks of life, and of old friends, contributed a host
of recollections that seemed little short of miraculous in their detailed
accounts of events of a scientific nature that were said to have occurred so
many years before. According to affidavits of Goebel himself and some of
his family, nothing that would anticipate Edison's claim had been omitted
from his work, for he (Goebel) claimed to have employed the all-glass
globe, into which were sealed platinum wires carrying a tenuous carbon
filament, from which the occluded gases had been liberated during the
process of high exhaustion. He had even determined upon bamboo as the
best material for filaments. On the face of it he was seemingly gifted with
more than human prescience, for in at least one of his exhibit lamps, said to
have been made twenty years previously, he claimed to have employed
processes which Edison and his associates had only developed by several
years of experience in making thousands of lamps!
The Goebel story was told by the affidavits in an ingenuous manner, with
a wealth of simple homely detail that carried on its face an appearance of
truth calculated to deceive the elect, had not the elect been somewhat
prepared by their investigation made some eleven years before.
The story was met by the Edison interests with counter-affidavits,
showing its utter improbabilities and absurdities from the standpoint of men
of science and others versed in the history and practice of the art; also
affidavits of other acquaintances and neighbors of Goebel flatly denying the
exhibitions he claimed to have made. The issue thus being joined, the legal
battle raged over different sections of the country. A number of
contumeliously defiant infringers in various cities based fond hopes of
lamp-manufacturing concerns, which during the long litigation had grown
strong and lusty, and thus far had not been enjoined by the court, now saw
injunctions staring them in the face, and in desperation set up the Goebel
so-called anticipation as a defence in the suits brought against them.

contumeliously defiant infringers in various cities based fond hopes of
Page 480
immunity upon the success of this Goebel evidence, but were defeated. The
attitude of the courts is well represented in the opinion of Judge Colt,
rendered in a motion for injunction against the Beacon Vacuum Pump and
Electrical Company. The defence alleged the Goebel anticipation, in
support of which it offered in evidence four lamps, Nos. 1, 2, and 3
purporting to have been made before 1854, and No. 4 before 1872. After a
very full review of the facts in the case, and a fair consideration of the
defendants' affidavits, Judge Colt in his opinion goes on to say:
"It is extremely improbable that Henry Goebel constructed a practical
incandescent lamp in 1854. This is manifest from the history of the art for
the past fifty years, the electrical laws which since that time have been
discovered as applicable to the incandescent lamp, the imperfect means
which then existed for obtaining a vacuum, the high degree of skill
necessary in the construction of all its parts, and the crude instruments with
which Goebel worked.
"Whether Goebel made the fiddle-bow lamps, 1, 2, and 3, is not
necessary to determine. The weight of evidence on this motion is in the
direction that he made these lamp or lamps similar in general appearance,
though it is manifest that few, if any, of the many witnesses who saw the
Goebel lamp could form an accurate judgment of the size of the filament or
burner. But assuming they were made, they do not anticipate the invention
of Edison. At most they were experimental toys used to advertise his
telescope, or to flash a light upon his clock, or to attract customers to his
shop. They were crudely constructed, and their life was brief. They could
not be used for domestic purposes. They were in no proper sense the
practical commercial lamp of Edison. The literature of the art is full of
better lamps, all of which are held not to anticipate the Edison patent.
"As for Lamp No. 4, I cannot but view it with suspicion. It presents a
new appearance. The reason given for not introducing it before the hearing
is unsatisfactory. This lamp, to my mind, envelops with a cloud of distrust
the whole Goebel story. It is simply impossible under the circumstances to
believe that a lamp so constructed could have been made by Goebel before
1872. Nothing in the evidence warrants such a supposition, and other things
show it to be untrue. This lamp has a carbon filament, platinum leading-in
wires, a good vacuum, and is well sealed and highly finished. It is said that
this lamp shows no traces of mercury in the bulb because the mercury was

this lamp shows no traces of mercury in the bulb because the mercury was
Page 481
distilled, but Goebel says nothing about distilled mercury in his first
affidavit, and twice he speaks of the particles of mercury clinging to the
inside of the chamber, and for that reason he constructed a Geissler pump
after he moved to 468 Grand Street, which was in 1877. Again, if this lamp
has been in his possession since before 1872, as he and his son swear, why
was it not shown to Mr. Crosby, of the American Company, when he visited
his shop in 1881 and was much interested in his lamps? Why was it not
shown to Mr. Curtis, the leading counsel for the defendants in the New York
cases, when he was asked to produce a lamp and promised to do so? Why
did not his son take this lamp to Mr. Bull's office in 1892, when he took the
old fiddle-bow lamps, 1, 2, and 3? Why did not his son take this lamp to Mr.
Eaton's office in 1882, when he tried to negotiate the sale of his father's
inventions to the Edison Company? A lamp so constructed and made before
1872 was worth a large sum of money to those interested in defeating the
Edison patent like the American Company, and Goebel was not a rich man.
Both he and one of his sons were employed in 1881 by the American
Company. Why did he not show this lamp to McMahon when he called in
the interest of the American Company and talked over the electrical
matters? When Mr. Dreyer tried to organize a company in 1882, and
procured an option from him of all his inventions relating to electric
lighting for which $925 was paid, and when an old lamp of this kind was of
vital consequence and would have insured a fortune, why was it not
forthcoming? Mr. Dreyer asked Goebel to produce an old lamp, and was
especially anxious to find one pending his negotiations with the Edison
Company for the sale of Goebel's inventions. Why did he not produce this
lamp in his interviews with Bohm, of the American Company, or Moses, of
the Edison Company, when it was for his interest to do so? The value of
such an anticipation of the Edison lamp was made known to him. He was
desirous of realizing upon his inventions. He was proud of his incandescent
lamps, and was pleased to talk about them with anybody who would listen.
Is it conceivable under all these circumstances, that he should have had this
all-important lamp in his possession from 1872 to 1893, and yet no one
have heard of it or seen it except his son? It cannot be said that ignorance of
the English language offers an excuse. He knew English very well although
Bohm and Dreyer conversed with him in German. His children spoke
English. Neither his ignorance nor his simplicity prevented him from taking
out three patents: the first in 1865 for a sewing-machine hemmer, and the
affidavit, and twice he speaks of the particles of mercury clinging to the
inside of the chamber, and for that reason he constructed a Geissler pump
after he moved to 468 Grand Street, which was in 1877. Again, if this lamp

last in 1882 for an improvement in incandescent lamps. If he made Lamp
No. 4 previous to 1872, why was it not also patented?
"There are other circumstances which throw doubt on this alleged Goebel
anticipation. The suit against the United States Electric Lighting Company
was brought in the Southern District of New York in 1885. Large interests
were at stake, and the main defence to the Edison patent was based on prior
inventions. This Goebel claim was then investigated by the leading counsel
for the defence, Mr. Curtis. It was further inquired into in 1892, in the case
against the Sawyer-Man Company. It was brought to the attention and
considered by the Edison Company in 1882. It was at that time known to
the American Company, who hoped by this means to defeat the monopoly
under the Edison patent. Dreyer tried to organize a company for its
purchase. Young Goebel tried to sell it. It must have been known to
hundreds of people. And now when the Edison Company after years of
litigation, leaving but a short time for the patent to run, have obtained a
final adjudication establishing its validity, this claim is again resurrected to
defeat the operation of the judgment so obtained. A court in equity should
not look with favor on such a defence. Upon the evidence here presented, I
agree with the first impression of Mr. Curtis and with the opinion of Mr.
Dickerson that whatever Goebel did must be considered as an abandoned
experiment.
"It has often been laid down that a meritorious invention is not to be
defeated by something which rests in speculation or experiment, or which is
rudimentary or incomplete.
"The law requires not conjecture, but certainty. It is easy after an
important invention has gone into public use for persons to come forward
with claims that they invented the same thing years before, and to endeavor
to establish this by the recollection of witnesses as to events long past. Such
evidence is to be received with great caution, and the presumption of
novelty arising from the grant of the patent is not to be overcome except
upon clear and convincing proof.
"When the defendant company entered upon the manufacture of
incandescent lamps in May, 1891, it well knew the consequences which
must follow a favorable decision for the Edison Company in the New York
case."
The injunction was granted.
No. 4 previous to 1872, why was it not also patented?

The injunction was granted.
Page 483
Other courts took practically the same view of the Goebel story as was
taken by Judge Colt, and the injunctions asked in behalf of the Edison
interests were granted on all applications except one in St. Louis, Missouri,
in proceedings instituted against a strong local concern of that city.
Thus, at the eleventh hour in the life of this important patent, after a long
period of costly litigation, Edison and his associates were compelled to
assume the defensive against a claimant whose utterly baseless pretensions
had already been thoroughly investigated and rejected years before by every
interested party, and ultimately, on examination by the courts, pronounced
legally untenable, if not indeed actually fraudulent. Irritating as it was to be
forced into the position of combating a proposition so well known to be
preposterous and insincere, there was nothing else to do but to fight this
fabrication with all the strenuous and deadly earnestness that would have
been brought to bear on a really meritorious defence. Not only did this
Goebel episode divert for a long time the energies of the Edison interests
from activities in other directions, but the cost of overcoming the
extravagantly absurd claims ran up into hundreds of thousands of dollars.
Another quotation from Major Eaton is of interest in this connection:
"Now a word about the Goebel case. I took personal charge of running
down this man and his pretensions in the section of the city where he lived
and among his old neighbors. They were a typical East Side lot—ignorant,
generally stupid, incapable of long memory, but ready to oblige a neighbor
and to turn an easy dollar by putting a cross-mark at the bottom of a
forthcoming friendly affidavit. I can say in all truth and justice that their
testimony was utterly false, and that the lawyers who took it must have
known it.
"The Goebel case emphasizes two defects in the court procedure in patent
cases. One is that they may be spun out almost interminably, even, possibly,
to the end of the life of the patent; the other is that the judge who decides
the case does not see the witnesses. That adverse decision at St. Louis
would never have been made if the court could have seen the men who
swore for Goebel. When I met Mr. F. P. Fish on his return from St. Louis,
after he had argued the Edison side, he felt keenly that disadvantage, to say
nothing of the hopeless difficulty of educating the court."
In the earliest days of the art, when it was apparent that incandescent
lighting had come to stay, the Edison Company was a shining mark at
taken by Judge Colt, and the injunctions asked in behalf of the Edison
interests were granted on all applications except one in St. Louis, Missouri,
in proceedings instituted against a strong local concern of that city.

forthcoming friendly affidavit. I can say in all truth and justice that their
testimony was utterly false, and that the lawyers who took it must have
known it.
"The Goebel case emphasizes two defects in the court procedure in patent
cases. One is that they may be spun out almost interminably, even, possibly,
to the end of the life of the patent; the other is that the judge who decides
the case does not see the witnesses. That adverse decision at St. Louis
would never have been made if the court could have seen the men who
swore for Goebel. When I met Mr. F. P. Fish on his return from St. Louis,
after he had argued the Edison side, he felt keenly that disadvantage, to say
nothing of the hopeless difficulty of educating the court."
In the earliest days of the art, when it was apparent that incandescent
lighting had come to stay, the Edison Company was a shining mark at
Page 484
which the shafts of the dishonest were aimed. Many there were who stood
ready to furnish affidavits that they or some one else whom they controlled
had really invented the lamp, but would obligingly withdraw and leave
Edison in possession of the field on payment of money. Investigation of
these cases, however, revealed invariably the purely fraudulent nature of all
such offers, which were uniformly declined.
As the incandescent light began to advance rapidly in public favor, the
immense proportions of the future market became sufficiently obvious to
tempt unauthorized persons to enter the field and become manufacturers.
When the lamp became a thoroughly established article it was not a difficult
matter to copy it, especially when there were employees to be hired away at
increased pay, and their knowledge utilized by the more unscrupulous of
these new competitors. This is not conjecture but known to be a fact, and
the practice continued many years, during which new lamp companies
sprang up on every side. Hence, it is not surprising that, on the whole, the
Edison lamp litigation was not less remarkable for quantity than quality.
Between eighty and ninety separate suits upon Edison's fundamental lamp
and detail patents were brought in the courts of the United States and
prosecuted to completion.
In passing it may be mentioned that in England France, and Germany
also the Edison fundamental lamp patent was stubbornly fought in the
judicial arena, and his claim to be the first inventor of practical
incandescent lighting was uniformly sustained in all those countries.
Infringement was not, however, confined to the lamp alone, but, in
America, extended all along the line of Edison's patents relating to the
production and distribution of electric light, including those on dynamos,
motors, distributing systems, sockets, switches, and other details which he
had from time to time invented. Consequently, in order to protect its
interests at all points, the Edison Company had found it necessary to pursue
a vigorous policy of instituting legal proceedings against the infringers of
these various patents, and, in addition to the large number of suits on the
lamp alone, not less than one hundred and twenty-five other separate
actions, involving some fifty or more of Edison's principal electric-lighting
patents, were brought against concerns which were wrongfully
appropriating his ideas and actively competing with his companies in the
market.

The ramifications of this litigation became so extensive and complex as
to render it necessary to institute a special bureau, or department, through
which the immense detail could be systematically sifted, analyzed, and
arranged in collaboration with the numerous experts and counsel
responsible for the conduct of the various cases. This department was
organized in 1889 by Major Eaton, who was at this time and for some years
afterward its general counsel.
In the selection of the head of this department a man of methodical and
analytical habit of mind was necessary, capable of clear reasoning, and at
the same time one who had gained a thoroughly practical experience in
electric light and power fields, and the choice fell upon Mr. W. J. Jenks, the
manager of the Edison central station at Brockton, Massachusetts. He had
resigned that position in 1885, and had spent the intervening period in
exploiting the Edison municipal system of lighting, as well as taking an
active part in various other branches of the Edison enterprises.
Thus, throughout the life of Edison's patents on electric light, power, and
distribution, the interminable legal strife has continued from day to day,
from year to year. Other inventors, some of them great and notable, have
been coming into the field since the foundation of the art, patents have
multiplied exceedingly, improvement has succeeded improvement, great
companies have grown greater, new concerns have come into existence,
coalitions and mergers have taken place, all tending to produce changes in
methods, but not much in diminution of patent litigation. While Edison has
not for a long time past interested himself particularly in electric light and
power inventions, the bureau which was initiated under the old regime in
1889 still continues, enlarged in scope, directed by its original chief, but
now conducted under the auspices of several allied companies whose great
volumes of combined patents (including those of Edison) cover a very wide
range of the electrical field.
As the general conception and theory of a lawsuit is the recovery of some
material benefit, the lay mind is apt to conceive of great sums of money
being awarded to a complainant by way of damages upon a favorable
decision in an important patent case. It might, therefore, be natural to ask
how far Edison or his companies have benefited pecuniarily by reason of
the many belated victories they have scored in the courts. To this question a
strict regard for truth compels the answer that they have not been benefited
to render it necessary to institute a special bureau, or department, through
which the immense detail could be systematically sifted, analyzed, and
arranged in collaboration with the numerous experts and counsel
responsible for the conduct of the various cases. This department was
organized in 1889 by Major Eaton, who was at this time and for some years

the many belated victories they have scored in the courts. To this question a
strict regard for truth compels the answer that they have not been benefited
Page 486
at all, not to the extent of a single dollar, so far as cash damages are
concerned.
It is not to be denied, however, that substantial advantages have accrued
to them more or less directly through the numerous favorable decisions
obtained by them as a result of the enormous amount of litigation, in the
prosecution of which so great a sum of money has been spent and so
concentrated an amount of effort and time lavished. Indeed, it would be
strange and unaccountable were the results otherwise. While the benefits
derived were not directly pecuniary in their nature, they were such as
tended to strengthen commercially the position of the rightful owners of the
patents. Many irresponsible and purely piratical concerns were closed
altogether; others were compelled to take out royalty licenses;
consolidations of large interests were brought about; the public was
gradually educated to a more correct view of the true merits of conflicting
claims, and, generally speaking, the business has been greatly unified and
brought within well-defined and controllable lines.
Not only in relation to his electric light and power inventions has the
progress of Edison and his associates been attended by legal controversy all
through the years of their exploitation, but also in respect to other
inventions, notably those relating to the phonograph and to motion pictures.
The increasing endeavors of infringers to divert into their own pockets
some of the proceeds arising from the marketing of the devices covered by
Edison's inventions on these latter lines, necessitated the institution by him,
some years ago, of a legal department which, as in the case of the light
inventions, was designed to consolidate all law and expert work and place it
under the management of a general counsel. The department is of
considerable extent, including a number of resident and other associate
counsel, and a general office staff, all of whom are constantly engaged from
day to day in patent litigation and other legal work necessary to protect the
Edison interests. Through their labors the old story is reiterated in the
contesting of approximate but conflicting claims, the never-ending effort to
suppress infringement, and the destruction as far as possible of the
commercial pirates who set sail upon the seas of all successful enterprises.
The details, circumstances, and technical questions are, of course, different
from those relating to other classes of inventions, and although there has
been no cause celebre concerning the phonograph and motion-picture
concerned.

The details, circumstances, and technical questions are, of course, different
from those relating to other classes of inventions, and although there has
been no cause celebre concerning the phonograph and motion-picture
Page 487
patents, the contention is as sharp and strenuous as it was in the cases
relating to electric lighting and heavy current technics.
Mr. Edison's storage battery and the poured cement house have not yet
reached the stage of great commercial enterprises, and therefore have not
yet risen to the dignity of patent litigation. If, however, the experience of
past years is any criterion, there will probably come a time in the future
when, despite present widely expressed incredulity and contemptuous sniffs
of unbelief in the practicability of his ideas in these directions, ultimate
success will give rise to a series of hotly contested legal conflicts such as
have signalized the practical outcome of his past efforts in other lines.
When it is considered what Edison has done, what the sum and substance
of his contributions to human comfort and happiness have been, the results,
as measured by legal success, have been pitiable. With the exception of the
favorable decision on the incandescent lamp filament patent, coming so
late, however, that but little practical good was accomplished, the reader
may search the law-books in vain for a single decision squarely and fairly
sustaining a single patent of first order. There never was a monopoly in
incandescent electric lighting, and even from the earliest days competitors
and infringers were in the field reaping the benefits, and though defeated in
the end, paying not a cent of tribute. The market was practically as free and
open as if no patent existed. There never was a monopoly in the
phonograph; practically all of the vital inventions were deliberately
appropriated by others, and the inventor was laughed at for his pains. Even
so beautiful a process as that for the duplication of phonograph records was
solemnly held by a Federal judge as lacking invention—as being obvious to
any one. The mere fact that Edison spent years of his life in developing that
process counted for nothing.
The invention of the three-wire system, which, when it was first
announced as saving over 60 per cent. of copper in the circuits, was
regarded as an utter impossibility—this patent was likewise held by a
Federal judge to be lacking in invention. In the motion-picture art,
infringements began with its very birth, and before the inevitable litigation
could be terminated no less than ten competitors were in the field, with
whom compromises had to be made.
In a foreign country, Edison would have undoubtedly received signal
honors; in his own country he has won the respect and admiration of
relating to electric lighting and heavy current technics.

millions; but in his chosen field as an inventor and as a patentee his reward
has been empty. The courts abroad have considered his patents in a liberal
spirit and given him his due; the decisions in this country have fallen wide
of the mark. We make no criticism of our Federal judges; as a body they are
fair, able, and hard-working; but they operate under a system of procedure
that stifles absolutely the development of inventive genius.
Until that system is changed and an opportunity offered for a final, swift,
and economical adjudication of patent rights, American inventors may well
hesitate before openly disclosing their inventions to the public, and may
seriously consider the advisability of retaining them as "trade secrets."

CHAPTER XXIX
THE SOCIAL SIDE OF EDISON
THE title of this chapter might imply that there is an unsocial side to
Edison. In a sense this is true, for no one is more impatient or intolerant of
interruption when deeply engaged in some line of experiment. Then the
caller, no matter how important or what his mission, is likely to realize his
utter insignificance and be sent away without accomplishing his object. But,
generally speaking, Edison is easy tolerance itself, with a peculiar weakness
toward those who have the least right to make any demands on his time.
Man is a social animal, and that describes Edison; but it does not describe
accurately the inventor asking to be let alone.
Edison never sought Society; but "Society" has never ceased to seek him,
and to-day, as ever, the pressure upon him to give up his work and receive
honors, meet distinguished people, or attend public functions, is intense.
Only two or three years ago, a flattering invitation came from one of the
great English universities to receive a degree, but at that moment he was
deep in experiments on his new storage battery, and nothing could budge
him. He would not drop the work, and while highly appreciative of the
proposed honor, let it go by rather than quit for a week or two the stern
drudgery of probing for the fact and the truth. Whether one approves or not,
it is at least admirable stoicism, of which the world has too little. A similar
instance is that of a visit paid to the laboratory by some one bringing a gold
medal from a foreign society. It was a very hot day in summer, the visitor
was in full social regalia of silk hat and frock-coat, and insisted that he
could deliver the medal only into Edison's hands. At that moment Edison,
stripped pretty nearly down to the buff, was at the very crisis of an
important experiment, and refused absolutely to be interrupted. He had
neither sought nor expected the medal; and if the delegate didn't care to
leave it he could take it away. At last Edison was overpersuaded, and, all
dirty and perspiring as he was, received the medal rather than cause the
visitor to come again. On one occasion, receiving a medal in New York,
Edison forgot it on the ferry-boat and left it behind him. A few years ago,

Edison forgot it on the ferry-boat and left it behind him. A few years ago,
Page 490
when Edison had received the Albert medal of the Royal Society of Arts,
one of the present authors called at the laboratory to see it. Nobody knew
where it was; hours passed before it could be found; and when at last the
accompanying letter was produced, it had an office date stamp right over
the signature of the royal president. A visitor to the laboratory with one of
these medallic awards asked Edison if he had any others. "Oh yes," he said,
"I have a couple of quarts more up at the house!" All this sounds like lack of
appreciation, but it is anything else than that. While in Paris, in 1889, he
wore the decoration of the Legion of Honor whenever occasion required,
but at all other times turned the badge under his lapel "because he hated to
have fellow-Americans think he was showing off." And any one who knows
Edison will bear testimony to his utter absence of ostentation. It may be
added that, in addition to the two quarts of medals up at the house, there
will be found at Glenmont many other signal tokens of esteem and good-
will—a beautiful cigar-case from the late Tsar of Russia, bronzes from the
Government of Japan, steel trophies from Krupp, and a host of other
mementos, to one of which he thus refers: "When the experiments with the
light were going on at Menlo Park, Sarah Bernhardt came to America. One
evening, Robert L. Cutting, of New York, brought her out to see the light.
She was a terrific 'rubberneck.' She jumped all over the machinery, and I
had one man especially to guard her dress. She wanted to know everything.
She would speak in French, and Cutting would translate into English. She
stayed there about an hour and a half. Bernhardt gave me two pictures,
painted by herself, which she sent me from Paris."
Reference has already been made to the callers upon Edison; and to give
simply the names of persons of distinction would fill many pages of this
record. Some were mere consumers of time; others were gladly welcomed,
like Lord Kelvin, the greatest physicist of the last century, with whom
Edison was always in friendly communication. "The first time I saw Lord
Kelvin, he came to my laboratory at Menlo Park in 1876." (He reported
most favorably on Edison's automatic telegraph system at the Philadelphia
Exposition of 1876.) "I was then experimenting with sending eight
messages simultaneously over a wire by means of synchronizing tuning-
forks. I would take a wire with similar apparatus at both ends, and would
throw it over on one set of instruments, take it away, and get it back so
quickly that you would not miss it, thereby taking advantage of the rapidity
of electricity to perform operations. On my local wire I got it to work very

Page 491
nicely. When Sir William Thomson (Kelvin) came in the room, he was
introduced to me, and had a number of friends with him. He said: 'What
have you here?' I told him briefly what it was. He then turned around, and
to my great surprise explained the whole thing to his friends. Quite a
different exhibition was given two weeks later by another well-known
Englishman, also an electrician, who came in with his friends, and I was
trying for two hours to explain it to him and failed."
After the introduction of the electric light, Edison was more than ever in
demand socially, but he shunned functions like the plague, not only because
of the serious interference with work, but because of his deafness. Some
dinners he had to attend, but a man who ate little and heard less could
derive practically no pleasure from them. "George Washington Childs was
very anxious I should go down to Philadelphia to dine with him. I seldom
went to dinners. He insisted I should go—that a special car would leave
New York. It was for me to meet Mr. Joseph Chamberlain. We had the
private car of Mr. Roberts, President of the Pennsylvania Railroad. We had
one of those celebrated dinners that only Mr. Childs could give, and I heard
speeches from Charles Francis Adams and different people. When I came
back to the depot, Mr. Roberts was there, and insisted on carrying my
satchel for me. I never could understand that."
Among the more distinguished visitors of the electric-lighting period was
President Diaz, with whom Edison became quite intimate. "President Diaz,
of Mexico, visited this country with Mrs. Diaz, a highly educated and
beautiful woman. She spoke very good English. They both took a deep
interest in all they saw. I don't know how it ever came about, as it is not in
my line, but I seemed to be delegated to show them around. I took them to
railroad buildings, electric-light plants, fire departments, and showed them
a great variety of things. It lasted two days." Of another visit Edison says:
"Sitting Bull and fifteen Sioux Indians came to Washington to see the Great
Father, and then to New York, and went to the Goerck Street works. We
could make some very good pyrotechnics there, so we determined to give
the Indians a scare. But it didn't work. We had an arc there of a most
terrifying character, but they never moved a muscle." Another episode at
Goerck Street did not find the visitors quite so stoical. "In testing dynamos
at Goerck Street we had a long flat belt running parallel with the floor,
about four inches above it, and travelling four thousand feet a minute. One
day one of the directors brought in three or four ladies to the works to see
introduced to me, and had a number of friends with him. He said: 'What
have you here?' I told him briefly what it was. He then turned around, and
to my great surprise explained the whole thing to his friends. Quite a
different exhibition was given two weeks later by another well-known

satchel for me. I never could understand that."
Among the more distinguished visitors of the electric-lighting period was
President Diaz, with whom Edison became quite intimate. "President Diaz,
of Mexico, visited this country with Mrs. Diaz, a highly educated and
beautiful woman. She spoke very good English. They both took a deep
interest in all they saw. I don't know how it ever came about, as it is not in
my line, but I seemed to be delegated to show them around. I took them to
railroad buildings, electric-light plants, fire departments, and showed them
a great variety of things. It lasted two days." Of another visit Edison says:
"Sitting Bull and fifteen Sioux Indians came to Washington to see the Great
Father, and then to New York, and went to the Goerck Street works. We
could make some very good pyrotechnics there, so we determined to give
the Indians a scare. But it didn't work. We had an arc there of a most
terrifying character, but they never moved a muscle." Another episode at
Goerck Street did not find the visitors quite so stoical. "In testing dynamos
at Goerck Street we had a long flat belt running parallel with the floor,
about four inches above it, and travelling four thousand feet a minute. One
day one of the directors brought in three or four ladies to the works to see
Page 492
the new electric-light system. One of the ladies had a little poodle led by a
string. The belt was running so smoothly and evenly, the poodle did not
notice the difference between it and the floor, and got into the belt before
we could do anything. The dog was whirled around forty or fifty times, and
a little flat piece of leather came out—and the ladies fainted."
A very interesting period, on the social side, was the visit paid by Edison
and his family to Europe in 1889, when he had made a splendid exhibit of
his inventions and apparatus at the great Paris Centennial Exposition of that
year, to the extreme delight of the French, who welcomed him with open
arms. The political sentiments that the Exposition celebrated were not such
as to find general sympathy in monarchical Europe, so that the "crowned
heads" were conspicuous by their absence. It was not, of course, by way of
theatrical antithesis that Edison appeared in Paris at such a time. But the
contrast was none the less striking and effective. It was felt that, after all,
that which the great exposition exemplified at its best—the triumph of
genius over matter, over ignorance, over superstition—met with its due
recognition when Edison came to participate, and to felicitate a noble nation
that could show so much in the victories of civilization and the arts, despite
its long trials and its long struggle for liberty. It is no exaggeration to say
that Edison was greeted with the enthusiastic homage of the whole French
people. They could find no praise warm enough for the man who had
"organized the echoes" and "tamed the lightning," and whose career was so
picturesque with eventful and romantic development. In fact, for weeks
together it seemed as though no Parisian paper was considered complete
and up to date without an article on Edison. The exuberant wit and fancy of
the feuilletonists seized upon his various inventions evolving from them
others of the most extraordinary nature with which to bedazzle and bewilder
the reader. At the close of the Exposition Edison was created a Commander
of the Legion of Honor. His own exhibit, made at a personal expense of
over $100,000, covered several thousand square feet in the vast Machinery
Hall, and was centred around a huge Edison lamp built of myriads of
smaller lamps of the ordinary size. The great attraction, however, was the
display of the perfected phonograph. Several instruments were provided,
and every day, all day long, while the Exposition lasted, queues of eager
visitors from every quarter of the globe were waiting to hear the little
machine talk and sing and reproduce their own voices. Never before was
such a collection of the languages of the world made. It was the first
string. The belt was running so smoothly and evenly, the poodle did not
notice the difference between it and the floor, and got into the belt before
we could do anything. The dog was whirled around forty or fifty times, and

machine talk and sing and reproduce their own voices. Never before was
such a collection of the languages of the world made. It was the first
Page 493
linguistic concourse since Babel times. We must let Edison tell the story of
some of his experiences:
"At the Universal Exposition at Paris, in 1889, I made a personal exhibit
covering about an acre. As I had no intention of offering to sell anything I
was showing, and was pushing no companies, the whole exhibition was
made for honor, and without any hope of profit. But the Paris newspapers
came around and wanted pay for notices of it, which we promptly refused;
whereupon there was rather a stormy time for a while, but nothing was
published about it.
"While at the Exposition I visited the Opera-House. The President of
France lent me his private box. The Opera-House was one of the first to be
lighted by the incandescent lamp, and the managers took great pleasure in
showing me down through the labyrinth containing the wiring, dynamos,
etc. When I came into the box, the orchestra played the 'Star-Spangled
Banner,' and all the people in the house arose; whereupon I was very much
embarrassed. After I had been an hour at the play, the manager came around
and asked me to go underneath the stage, as they were putting on a ballet of
300 girls, the finest ballet in Europe. It seems there is a little hole on the
stage with a hood over it, in which the prompter sits when opera is given. In
this instance it was not occupied, and I was given the position in the
prompter's seat, and saw the whole ballet at close range.
"The city of Paris gave me a dinner at the new Hotel de Ville, which was
also lighted with the Edison system. They had a very fine installation of
machinery. As I could not understand or speak a word of French, I went to
see our minister, Mr. Whitelaw Reid, and got him to send a deputy to
answer for me, which he did, with my grateful thanks. Then the telephone
company gave me a dinner, and the engineers of France; and I attended the
dinner celebrating the fiftieth anniversary of the discovery of photography.
Then they sent to Reid my decoration, and they tried to put a sash on me,
but I could not stand for that. My wife had me wear the little red button, but
when I saw Americans coming I would slip it out of my lapel, as I thought
they would jolly me for wearing it."
Nor was this all. Edison naturally met many of the celebrities of France:
"I visited the Eiffel Tower at the invitation of Eiffel. We went to the top,
where there was an extension and a small place in which was Eiffel's
private office. In this was a piano. When my wife and I arrived at the top,
some of his experiences:

Page 494
we found that Gounod, the composer, was there. We stayed a couple of
hours, and Gounod sang and played for us. We spent a day at Meudon, an
old palace given by the government to Jansen, the astronomer. He occupied
three rooms, and there were 300. He had the grand dining-room for his
laboratory. He showed me a gyroscope he had got up which made the
incredible number of 4000 revolutions in a second. A modification of this
was afterward used on the French Atlantic lines for making an artificial
horizon to take observations for position at sea. In connection with this a
gentleman came to me a number of years afterward, and I got out a part of
some plans for him. He wanted to make a gigantic gyroscope weighing
several tons, to be run by an electric motor and put on a sailing ship. He
wanted this gyroscope to keep a platform perfectly horizontal, no matter
how rough the sea was. Upon this platform he was going to mount a
telescope to observe an eclipse off the Gold Coast of Africa. But for some
reason it was never completed.
"Pasteur invited me to come down to the Institute, and I went and had
quite a chat with him. I saw a large number of persons being inoculated, and
also the whole modus operandi, which was very interesting. I saw one
beautiful boy about ten, the son of an English lord. His father was with him.
He had been bitten in the face, and was taking the treatment. I said to
Pasteur, 'Will he live?' 'No,' said he, 'the boy will be dead in six days. He
was bitten too near the top of the spinal column, and came too late!'"
Edison has no opinion to offer as an expert on art, but has his own
standard of taste: "Of course I visited the Louvre and saw the Old Masters,
which I could not enjoy. And I attended the Luxembourg, with modern
masters, which I enjoyed greatly. To my mind, the Old Masters are not art,
and I suspect that many others are of the same opinion; and that their value
is in their scarcity and in the variety of men with lots of money." Somewhat
akin to this is a shrewd comment on one feature of the Exposition: "I spent
several days in the Exposition at Paris. I remember going to the exhibit of
the Kimberley diamond mines, and they kindly permitted me to take
diamonds from some of the blue earth which they were washing by
machinery to exhibit the mine operations. I found several beautiful
diamonds, but they seemed a little light weight to me when I was picking
them out. They were diamonds for exhibition purposes —probably glass."

This did not altogether complete the European trip of 1889, for Edison
wished to see Helmholtz. "After leaving Paris we went to Berlin. The
French papers then came out and attacked me because I went to Germany;
and said I was now going over to the enemy. I visited all the things of
interest in Berlin; and then on my way home I went with Helmholtz and
Siemens in a private compartment to the meeting of the German
Association of Science at Heidelberg, and spent two days there. When I
started from Berlin on the trip, I began to tell American stories. Siemens
was very fond of these stories and would laugh immensely at them, and
could see the points and the humor, by his imagination; but Helmholtz
could not see one of them. Siemens would quickly, in German, explain the
point, but Helmholtz could not see it, although he understood English,
which Siemens could speak. Still the explanations were made in German. I
always wished I could have understood Siemens's explanations of the points
of those stories. At Heidelberg, my assistant, Mr. Wangemann, an
accomplished German-American, showed the phonograph before the
Association."
Then came the trip from the Continent to England, of which this will
certainly pass as a graphic picture: "When I crossed over to England I had
heard a good deal about the terrors of the English Channel as regards
seasickness. I had been over the ocean three times and did not know what
seasickness was, so far as I was concerned myself. I was told that while a
man might not get seasick on the ocean, if he met a good storm on the
Channel it would do for him. When we arrived at Calais to cross over,
everybody made for the restaurant. I did not care about eating, and did not
go to the restaurant, but my family did. I walked out and tried to find the
boat. Going along the dock I saw two small smokestacks sticking up, and
looking down saw a little boat. 'Where is the steamer that goes across the
Channel?' 'This is the boat.' There had been a storm in the North Sea that
had carried away some of the boats on the German steamer, and it certainly
looked awful tough outside. I said to the man: 'Will that boat live in that
sea?' 'Oh yes,' he said, 'but we've had a bad storm.' So I made up my mind
that perhaps I would get sick this time. The managing director of the
English railroad owning this line was Forbes, who heard I was coming over,
and placed the private saloon at my disposal. The moment my family got in
the room with the French lady's maid and the rest, they commenced to get
sick, so I felt pretty sure I was in for it. We started out of the little inlet and
wished to see Helmholtz. "After leaving Paris we went to Berlin. The

the room with the French lady's maid and the rest, they commenced to get
sick, so I felt pretty sure I was in for it. We started out of the little inlet and
Page 496
got into the Channel, and that boat went in seventeen directions
simultaneously. I waited awhile to see what was going to occur, and then
went into the smoking-compartment. Nobody was there. By-and-by the fun
began. Sounds of all kinds and varieties were heard in every direction. They
were all sick. There must have been 100 people aboard. I didn't see a single
exception except the waiters and myself. I asked one of the waiters
concerning the boat itself, and was taken to see the engineer, and went
down to look at the engines, and saw the captain. But I kept mostly in the
smoking-room. I was smoking a big cigar, and when a man looked in I
would give a big puff, and every time they saw that they would go away
and begin again. The English Channel is a holy terror, all right, but it didn't
affect me. I must be out of balance."
While in Paris, Edison had met Sir John Pender, the English "cable king,"
and had received an invitation from him to make a visit to his country
residence: "Sir John Pender, the master of the cable system of the world at
that time, I met in Paris. I think he must have lived among a lot of people
who were very solemn, because I went out riding with him in the Bois de
Boulogne and started in to tell him American stories. Although he was a
Scotchman he laughed immoderately. He had the faculty of understanding
and quickly seeing the point of the stories; and for three days after I could
not get rid of him. Finally I made him a promise that I would go to his
country house at Foot's Cray, near London. So I went there, and spent two
or three days telling him stories.
"While at Foot's Cray, I met some of the backers of Ferranti, then putting
up a gigantic alternating-current dynamo near London to send ten or fifteen
thousand volts up into the main district of the city for electric lighting. I
think Pender was interested. At any rate the people invited to dinner were
very much interested, and they questioned me as to what I thought of the
proposition. I said I hadn't any thought about it, and could not give any
opinion until I saw it. So I was taken up to London to see the dynamo in
course of construction and the methods employed; and they insisted I
should give them some expression of my views. While I gave them my
opinion, it was reluctantly; I did not want to do so. I thought that
commercially the thing was too ambitious, that Ferranti's ideas were too
big, just then; that he ought to have started a little smaller until he was sure.
I understand that this installation was not commercially successful, as there
simultaneously. I waited awhile to see what was going to occur, and then
went into the smoking-compartment. Nobody was there. By-and-by the fun

were a great many troubles. But Ferranti had good ideas, and he was no
small man."
Incidentally it may be noted here that during the same year (1889) the
various manufacturing Edison lighting interests in America were brought
together, under the leadership of Mr. Henry Villard, and consolidated in the
Edison General Electric Company with a capital of no less than
$12,000,000 on an eight-per-cent.-dividend basis. The numerous Edison
central stations all over the country represented much more than that sum,
and made a splendid outlet for the product of the factories. A few years later
came the consolidation with the Thomson-Houston interests in the General
Electric Company, which under the brilliant and vigorous management of
President C. A. Coffin has become one of the greatest manufacturing
institutions of the country, with an output of apparatus reaching toward
$75,000,000 annually. The net result of both financial operations was,
however, to detach Edison from the special field of invention to which he
had given so many of his most fruitful years; and to close very definitely
that chapter of his life, leaving him free to develop other ideas and interests
as set forth in these volumes.
It might appear strange on the surface, but one of the reasons that most
influenced Edison to regrets in connection with the "big trade" of 1889 was
that it separated him from his old friend and ally, Bergmann, who, on
selling out, saw a great future for himself in Germany, went there, and
realized it. Edison has always had an amused admiration for Bergmann, and
his "social side" is often made evident by his love of telling stories about
those days of struggle. Some of the stories were told for this volume.
"Bergmann came to work for me as a boy," says Edison. "He started in on
stock-quotation printers. As he was a rapid workman and paid no attention
to the clock, I took a fancy to him, and gave him piece-work. He contrived
so many little tools to cheapen the work that he made lots of money. I even
helped him get up tools until it occurred to me that this was too rapid a
process of getting rid of my money, as I hadn't the heart to cut the price
when it was originally fair. After a year or so, Bergmann got enough money
to start a small shop in Wooster Street, New York, and it was at this shop
that the first phonographs were made for sale. Then came the carbon
telephone transmitter, a large number of which were made by Bergmann for
the Western Union. Finally came the electric light. A dynamo was installed
in Bergmann's shop to permit him to test the various small devices which he
small man."

in Bergmann's shop to permit him to test the various small devices which he
Page 498
was then making for the system. He rented power from a Jew who owned
the building. Power was supplied from a fifty-horse-power engine to other
tenants on the several floors. Soon after the introduction of the big dynamo
machine, the landlord appeared in the shop and insisted that Bergmann was
using more power than he was paying for, and said that lately the belt on the
engine was slipping and squealing. Bergmann maintained that he must be
mistaken. The landlord kept going among his tenants and finally discovered
the dynamo. 'Oh! Mr. Bergmann, now I know where my power goes to,'
pointing to the dynamo. Bergmann gave him a withering look of scorn, and
said, 'Come here and I will show you.' Throwing off the belt and
disconnecting the wires, he spun the armature around by hand. 'There,' said
Bergmann, 'you see it's not here that you must look for your loss.' This
satisfied the landlord, and he started off to his other tenants. He did not
know that that machine, when the wires were connected, could stop his
engine.
"Soon after, the business had grown so large that E. H. Johnson and I
went in as partners, and Bergmann rented an immense factory building at
the corner of Avenue B and East Seventeenth Street, New York, six stories
high and covering a quarter of a block. Here were made all the small things
used on the electric-lighting system, such as sockets, chandeliers, switches,
meters, etc. In addition, stock tickers, telephones, telephone switchboards,
and typewriters were made the Hammond typewriters were perfected and
made there. Over 1500 men were finally employed. This shop was very
successful both scientifically and financially. Bergmann was a man of great
executive ability and carried economy of manufacture to the limit. Among
all the men I have had associated with me, he had the commercial instinct
most highly developed."
One need not wonder at Edison's reminiscent remark that, "In any trade
any of my 'boys' made with Bergmann he always got the best of them, no
matter what it was. One time there was to be a convention of the managers
of Edison illuminating companies at Chicago. There were a lot of
representatives from the East, and a private car was hired. At Jersey City a
poker game was started by one of the delegates. Bergmann was induced to
enter the game. This was played right through to Chicago without any sleep,
but the boys didn't mind that. I had gotten them immune to it. Bergmann
had won all the money, and when the porter came in and said 'Chicago,'
the building. Power was supplied from a fifty-horse-power engine to other
tenants on the several floors. Soon after the introduction of the big dynamo
machine, the landlord appeared in the shop and insisted that Bergmann was
using more power than he was paying for, and said that lately the belt on the
engine was slipping and squealing. Bergmann maintained that he must be
mistaken. The landlord kept going among his tenants and finally discovered
the dynamo. 'Oh! Mr. Bergmann, now I know where my power goes to,'
pointing to the dynamo. Bergmann gave him a withering look of scorn, and
said, 'Come here and I will show you.' Throwing off the belt and
disconnecting the wires, he spun the armature around by hand. 'There,' said
Bergmann, 'you see it's not here that you must look for your loss.' This
satisfied the landlord, and he started off to his other tenants. He did not
know that that machine, when the wires were connected, could stop his
engine.
"Soon after, the business had grown so large that E. H. Johnson and I
went in as partners, and Bergmann rented an immense factory building at
the corner of Avenue B and East Seventeenth Street, New York, six stories
high and covering a quarter of a block. Here were made all the small things
used on the electric-lighting system, such as sockets, chandeliers, switches,
meters, etc. In addition, stock tickers, telephones, telephone switchboards,
and typewriters were made the Hammond typewriters were perfected and

Bergmann jumped up and said: 'What! Chicago! I thought it was only
Philadelphia!'"
But perhaps this further story is a better indication of developed humor
and shrewdness: "A man by the name of Epstein had been in the habit of
buying brass chips and trimmings from the lathes, and in some way
Bergmann found out that he had been cheated. This hurt his pride, and he
determined to get even. One day Epstein appeared and said: 'Good-
morning, Mr. Bergmann, have you any chips to-day?' 'No,' said Bergmann,
'I have none.' 'That's strange, Mr. Bergmann; won't you look?' No, he
wouldn't look; he knew he had none. Finally Epstein was so persistent that
Bergmann called an assistant and told him to go and see if he had any chips.
He returned and said they had the largest and finest lot they ever had.
Epstein went up to several boxes piled full of chips, and so heavy that he
could not lift even one end of a box. 'Now, Mr. Bergmann,' said Epstein,
'how much for the lot?' 'Epstein,' said Bergmann, 'you have cheated me, and
I will no longer sell by the lot, but will sell only by the pound.' No amount
of argument would apparently change Bergmann's determination to sell by
the pound, but finally Epstein got up to $250 for the lot, and Bergmann,
appearing as if disgusted, accepted and made him count out the money.
Then he said: 'Well, Epstein, good-bye, I've got to go down to Wall Street.'
Epstein and his assistant then attempted to lift the boxes to carry them out,
but couldn't; and then discovered that calculations as to quantity had been
thrown out because the boxes had all been screwed down to the floor and
mostly filled with boards with a veneer of brass chips. He made such a
scene that he had to be removed by the police. I met him several days
afterward and he said he had forgiven Mr. Bergmann, as he was such a
smart business man, and the scheme was so ingenious.
"One day as a joke I filled three or four sheets of foolscap paper with a
jumble of figures and told Bergmann they were calculations showing the
great loss of power from blowing the factory whistle. Bergmann thought it
real, and never after that would he permit the whistle to blow."
Another glimpse of the "social side" is afforded in the following little
series of pen-pictures of the same place and time: "I had my laboratory at
the top of the Bergmann works, after moving from Menlo Park. The
building was six stories high. My father came there when he was eighty
years of age. The old man had powerful lungs. In fact, when I was
Philadelphia!'"

the top of the Bergmann works, after moving from Menlo Park. The
building was six stories high. My father came there when he was eighty
years of age. The old man had powerful lungs. In fact, when I was
Page 500
examined by the Mutual Life Insurance Company, in 1873, my lung
expansion was taken by the doctor, and the old gentleman was there at the
time. He said to the doctor: 'I wish you would take my lung expansion, too.'
The doctor took it, and his surprise was very great, as it was one of the
largest on record. I think it was five and one-half inches. There were only
three or four could beat it. Little Bergmann hadn't much lung power. The
old man said to him, one day: 'Let's run up-stairs.' Bergmann agreed and ran
up. When they got there Bergmann was all done up, but my father never
showed a sign of it. There was an elevator there, and each day while it was
travelling up I held the stem of my Waterbury watch up against the column
in the elevator shaft and it finished the winding by the time I got up the six
stories." This original method of reducing the amount of physical labor
involved in watch-winding brings to mind another instance of shrewdness
mentioned by Edison, with regard to his newsboy days. Being asked
whether he did not get imposed upon with bad bank-bills, he replied that he
subscribed to a bank-note detector and consulted it closely whenever a note
of any size fell into his hands. He was then less than fourteen years old.
The conversations with Edison that elicited these stories brought out
some details as to peril that attends experimentation. He has confronted
many a serious physical risk, and counts himself lucky to have come
through without a scratch or scar. Four instances of personal danger may be
noted in his own language: "When I started at Menlo, I had an electric
furnace for welding rare metals that I did not know about very clearly. I was
in the dark-room, where I had a lot of chloride of sulphur, a very corrosive
liquid. I did not know that it would decompose by water. I poured in a
beakerful of water, and the whole thing exploded and threw a lot of it into
my eyes. I ran to the hydrant, leaned over backward, opened my eyes, and
ran the hydrant water right into them. But it was two weeks before I could
see.
"The next time we just saved ourselves. I was making some stuff to squirt
into filaments for the incandescent lamp. I made about a pound of it. I had
used ammonia and bromine. I did not know it at the time, but I had made
bromide of nitrogen. I put the large bulk of it in three filters, and after it had
been washed and all the water had come through the filter, I opened the
three filters and laid them on a hot steam plate to dry with the stuff. While I
and Mr. Sadler, one of my assistants, were working near it, there was a
sudden flash of light, and a very smart explosion. I said to Sadler: 'What is

that?' 'I don't know,' he said, and we paid no attention. In about half a
minute there was a sharp concussion, and Sadler said: 'See, it is that stuff on
the steam plate.' I grabbed the whole thing and threw it in the sink, and
poured water on it. I saved a little of it and found it was a terrific explosive.
The reason why those little preliminary explosions took place was that a
little had spattered out on the edge of the filter paper, and had dried first and
exploded. Had the main body exploded there would have been nothing left
of the laboratory I was working in.
"At another time, I had a briquetting machine for briquetting iron ore. I
had a lever held down by a powerful spring, and a rod one inch in diameter
and four feet long. While I was experimenting with it, and standing beside
it, a washer broke, and that spring threw the rod right up to the ceiling with
a blast; and it came down again just within an inch of my nose, and went
clear through a two-inch plank. That was 'within an inch of your life,' as
they say.
"In my experimental plant for concentrating iron ore in the northern part
of New Jersey, we had a vertical drier, a column about nine feet square and
eighty feet high. At the bottom there was a space where two men could go
through a hole; and then all the rest of the column was filled with baffle
plates. One day this drier got blocked, and the ore would not run down. So I
and the vice-president of the company, Mr. Mallory, crowded through the
manhole to see why the ore would not come down. After we got in, the ore
did come down and there were fourteen tons of it above us. The men
outside knew we were in there, and they had a great time digging us out and
getting air to us."
Such incidents brought out in narration the fact that many of the men
working with him had been less fortunate, particularly those who had
experimented with the Roentgen X-ray, whose ravages, like those of
leprosy, were responsible for the mutilation and death of at least one expert
assistant. In the early days of work on the incandescent lamp, also, there
was considerable trouble with mercury. "I had a series of vacuum-pumps
worked by mercury and used for exhausting experimental incandescent
lamps. The main pipe, which was full of mercury, was about seven and one-
half feet from the floor. Along the length of the pipe were outlets to which
thick rubber tubing was connected, each tube to a pump. One day, while
experimenting with the mercury pump, my assistant, an awkward country

Page 502
lad from a farm on Staten Island, who had adenoids in his nose and
breathed through his mouth, which was always wide open, was looking up
at this pipe, at a small leak of mercury, when the rubber tube came off and
probably two pounds of mercury went into his mouth and down his throat,
and got through his system somehow. In a short time he became salivated,
and his teeth got loose. He went home, and shortly his mother appeared at
the laboratory with a horsewhip, which she proposed to use on the
proprietor. I was fortunately absent, and she was mollified somehow by my
other assistants. I had given the boy considerable iodide of potassium to
prevent salivation, but it did no good in this case.
"When the first lamp-works were started at Menlo Park, one of my
experiments seemed to show that hot mercury gave a better vacuum in the
lamp than cold mercury. I thereupon started to heat it. Soon all the men got
salivated, and things looked serious; but I found that in the mirror factories,
where mercury was used extensively, the French Government made the
giving of iodide of potassium compulsory to prevent salivation. I carried
out this idea, and made every man take a dose every day, but there was
great opposition, and hot mercury was finally abandoned."
It will have been gathered that Edison has owed his special immunity
from "occupational diseases" not only to luck but to unusual powers of
endurance, and a strong physique, inherited, no doubt, from his father. Mr.
Mallory mentions a little fact that bears on this exceptional quality of bodily
powers. "I have often been surprised at Edison's wonderful capacity for the
instant visual perception of differences in materials that were invisible to
others until he would patiently point them out. This had puzzled me for
years, but one day I was unexpectedly let into part of the secret. For some
little time past Mr. Edison had noticed that he was bothered somewhat in
reading print, and I asked him to have an oculist give him reading-glasses.
He partially promised, but never took time to attend to it. One day he and I
were in the city, and as Mrs. Edison had spoken to me about it, and as we
happened to have an hour to spare, I persuaded him to go to an oculist with
me. Using no names, I asked the latter to examine the gentleman's eyes. He
did so very conscientiously, and it was an interesting experience, for he was
kept busy answering Mr. Edison's numerous questions. When the oculist
finished, he turned to me and said: 'I have been many years in the business,
but have never seen an optic nerve like that of this gentleman. An ordinary

optic nerve is about the thickness of a thread, but his is like a cord. He must
be a remarkable man in some walk of life. Who is he?'"
It has certainly required great bodily vigor and physical capacity to
sustain such fatigue as Edison has all his life imposed upon himself, to the
extent on one occasion of going five days without sleep. In a conversation
during 1909, he remarked, as though it were nothing out of the way, that up
to seven years previously his average of daily working hours was nineteen
and one-half, but that since then he figured it at eighteen. He said he stood it
easily, because he was interested in everything, and was reading and
studying all the time. For instance, he had gone to bed the night before
exactly at twelve and had arisen at 4.30 A. M. to read some New York law
reports. It was suggested that the secret of it might be that he did not live in
the past, but was always looking forward to a greater future, to which he
replied: "Yes, that's it. I don't live with the past; I am living for to-day and
to-morrow. I am interested in every department of science, arts, and
manufacture. I read all the time on astronomy, chemistry, biology, physics,
music, metaphysics, mechanics, and other branches—political economy,
electricity, and, in fact, all things that are making for progress in the world.
I get all the proceedings of the scientific societies, the principal scientific
and trade journals, and read them. I also read The Clipper, The Police
Gazette, The Billboard, The Dramatic Mirror, and a lot of similar
publications, for I like to know what is going on. In this way I keep up to
date, and live in a great moving world of my own, and, what's more, I enjoy
every minute of it." Referring to some event of the past, he said: "Spilt milk
doesn't interest me. I have spilt lots of it, and while I have always felt it for
a few days, it is quickly forgotten, and I turn again to the future." During
another talk on kindred affairs it was suggested to Edison that, as he had
worked so hard all his life, it was about time for him to think somewhat of
the pleasures of travel and the social side of life. To which he replied
laughingly: "I already have a schedule worked out. From now until I am
seventy-five years of age, I expect to keep more or less busy with my
regular work, not, however, working as many hours or as hard as I have in
the past. At seventy five I expect to wear loud waistcoats with fancy
buttons; also gaiter tops; at eighty I expect to learn how to play bridge whist
and talk foolishly to the ladies. At eighty-five I expect to wear a full-dress
suit every evening at dinner, and at ninety—well, I never plan more than
thirty years ahead."

The reference to clothes is interesting, as it is one of the few subjects in
which Edison has no interest. It rather bores him. His dress is always of the
plainest; in fact, so plain that, at the Bergmann shops in New York, the
children attending a parochial Catholic school were wont to salute him with
the finger to the head, every time he went by. Upon inquiring, he found that
they took him for a priest, with his dark garb, smooth-shaven face, and
serious expression. Edison says: "I get a suit that fits me; then I compel the
tailors to use that as a jig or pattern or blue-print to make others by. For
many years a suit was used as a measurement; once or twice they took fresh
measurements, but these didn't fit and they had to go back. I eat to keep my
weight constant, hence I need never change measurements." In regard to
this, Mr. Mallory furnishes a bit of chat as follows: "In a lawsuit in which I
was a witness, I went out to lunch with the lawyers on both sides, and the
lawyer who had been cross-examining me stated that he had for a client a
Fifth Avenue tailor, who had told him that he had made all of Mr. Edison's
clothes for the last twenty years, and that he had never seen him. He said
that some twenty years ago a suit was sent to him from Orange, and
measurements were made from it, and that every suit since had been made
from these measurements. I may add, from my own personal observation,
that in Mr. Edison's clothes there is no evidence but that every new suit that
he has worn in that time looks as if he had been specially measured for it,
which shows how very little he has changed physically in the last twenty
years."
Edison has never had any taste for amusements, although he will indulge
in the game of "Parchesi" and has a billiard-table in his house. The coming
of the automobile was a great boon to him, because it gave him a form of
outdoor sport in which he could indulge in a spirit of observation, without
the guilty feeling that he was wasting valuable time. In his automobile he
has made long tours, and with his family has particularly indulged his taste
for botany. That he has had the usual experience in running machines will
be evidenced by the following little story from Mr. Mallory: "About three
years ago I had a motor-car of a make of which Mr. Edison had already two
cars; and when the car was received I made inquiry as to whether any repair
parts were carried by any of the various garages in Easton, Pennsylvania,
near our cement works. I learned that this particular car was the only one in
Easton. Knowing that Mr. Edison had had an experience lasting two or
three years with this particular make of car, I determined to ask him for
which Edison has no interest. It rather bores him. His dress is always of the
plainest; in fact, so plain that, at the Bergmann shops in New York, the
children attending a parochial Catholic school were wont to salute him with
the finger to the head, every time he went by. Upon inquiring, he found that

this, Mr. Mallory furnishes a bit of chat as follows: "In a lawsuit in which I
was a witness, I went out to lunch with the lawyers on both sides, and the
lawyer who had been cross-examining me stated that he had for a client a
Fifth Avenue tailor, who had told him that he had made all of Mr. Edison's
clothes for the last twenty years, and that he had never seen him. He said
that some twenty years ago a suit was sent to him from Orange, and
measurements were made from it, and that every suit since had been made
from these measurements. I may add, from my own personal observation,
that in Mr. Edison's clothes there is no evidence but that every new suit that
he has worn in that time looks as if he had been specially measured for it,
which shows how very little he has changed physically in the last twenty
years."
Edison has never had any taste for amusements, although he will indulge
in the game of "Parchesi" and has a billiard-table in his house. The coming
of the automobile was a great boon to him, because it gave him a form of
outdoor sport in which he could indulge in a spirit of observation, without
the guilty feeling that he was wasting valuable time. In his automobile he
has made long tours, and with his family has particularly indulged his taste
for botany. That he has had the usual experience in running machines will
be evidenced by the following little story from Mr. Mallory: "About three
years ago I had a motor-car of a make of which Mr. Edison had already two
cars; and when the car was received I made inquiry as to whether any repair
parts were carried by any of the various garages in Easton, Pennsylvania,
near our cement works. I learned that this particular car was the only one in
Easton. Knowing that Mr. Edison had had an experience lasting two or
three years with this particular make of car, I determined to ask him for
Page 505
information relative to repair parts; so the next time I was at the laboratory I
told him I was unable to get any repair parts in Easton, and that I wished to
order some of the most necessary, so that, in case of breakdowns, I would
not be compelled to lose the use of the car for several days until the parts
came from the automobile factory. I asked his advice as to what I should
order, to which he replied: 'I don't think it will be necessary to order an
extra top.'" Since that episode, which will probably be appreciated by most
automobilists, Edison has taken up the electric automobile, and is now
using it as well as developing it. One of the cars equipped with his battery is
the Bailey, and Mr. Bee tells the following story in regard to it: "One day
Colonel Bailey, of Amesbury, Massachusetts, who was visiting the
Automobile Show in New York, came out to the laboratory to see Mr.
Edison, as the latter had expressed a desire to talk with him on his next visit
to the metropolis. When he arrived at the laboratory, Mr. Edison, who had
been up all night experimenting, was asleep on the cot in the library. As a
rule we never wake Mr. Edison from sleep, but as he wanted to see Colonel
Bailey, who had to go, I felt that an exception should be made, so I went
and tapped him on the shoulder. He awoke at once, smiling, jumped up, was
instantly himself as usual, and advanced and greeted the visitor. His very
first question was: 'Well, Colonel, how did you come out on that
experiment?'—referring to some suggestions he had made at their last
meeting a year before. For a minute Colonel Bailey did not recall what was
referred to; but a few words from Mr. Edison brought it back to his
remembrance, and he reported that the results had justified Mr. Edison's
expectations."
It might be expected that Edison would have extreme and even radical
ideas on the subject of education—and he has, as well as a perfect readiness
to express them, because he considers that time is wasted on things that are
not essential: "What we need," he has said, "are men capable of doing work.
I wouldn't give a penny for the ordinary college graduate, except those from
the institutes of technology. Those coming up from the ranks are a darned
sight better than the others. They aren't filled up with Latin, philosophy, and
the rest of that ninny stuff." A further remark of his is: "What the country
needs now is the practical skilled engineer, who is capable of doing
everything. In three or four centuries, when the country is settled, and
commercialism is diminished, there will be time for the literary men. At
present we want engineers, industrial men, good business-like managers,

Page 506
and railroad men." It is hardly to be marvelled at that such views should
elicit warm protest, summed up in the comment: "Mr. Edison and many like
him see in reverse the course of human progress. Invention does not smooth
the way for the practical men and make them possible. There is always too
much danger of neglecting thoughts for things, ideas for machinery. No
theory of education that aggravates this danger is consistent with national
well-being."
Edison is slow to discuss the great mysteries of life, but is of reverential
attitude of mind, and ever tolerant of others' beliefs. He is not a religious
man in the sense of turning to forms and creeds, but, as might be expected,
is inclined as an inventor and creator to argue from the basis of "design"
and thence to infer a designer. "After years of watching the processes of
nature," he says, "I can no more doubt the existence of an Intelligence that
is running things than I do of the existence of myself. Take, for example,
the substance water that forms the crystals known as ice. Now, there are
hundreds of combinations that form crystals, and every one of them, save
ice, sinks in water. Ice, I say, doesn't, and it is rather lucky for us mortals,
for if it had done so, we would all be dead. Why? Simply because if ice
sank to the bottoms of rivers, lakes, and oceans as fast as it froze, those
places would be frozen up and there would be no water left. That is only
one example out of thousands that to me prove beyond the possibility of a
doubt that some vast Intelligence is governing this and other planets."
A few words as to the domestic and personal side of Edison's life, to
which many incidental references have already been made in these pages.
He was married in 1873 to Miss Mary Stillwell, who died in 1884, leaving
three children—Thomas Alva, William Leslie, and Marion Estelle.
Mr. Edison was married again in 1886 to Miss Mina Miller, daughter of
Mr. Lewis Miller, a distinguished pioneer inventor and manufacturer in the
field of agricultural machinery, and equally entitled to fame as the father of
the "Chautauqua idea," and the founder with Bishop Vincent of the original
Chautauqua, which now has so many replicas all over the country, and
which started in motion one of the great modern educational and moral
forces in America. By this marriage there are three children—Charles,
Madeline, and Theodore.
For over a score of years, dating from his marriage to Miss Miller,
Edison's happy and perfect domestic life has been spent at Glenmont, a

For over a score of years, dating from his marriage to Miss Miller,
Edison's happy and perfect domestic life has been spent at Glenmont, a
Page 507
beautiful property acquired at that time in Llewellyn Park, on the higher
slopes of Orange Mountain, New Jersey, within easy walking distance of
the laboratory at the foot of the hill in West Orange. As noted already, the
latter part of each winter is spent at Fort Myers, Florida, where Edison has,
on the banks of the Calahoutchie River, a plantation home that is in many
ways a miniature copy of the home and laboratory up North. Glenmont is a
rather elaborate and florid building in Queen Anne English style, of brick,
stone, and wooden beams showing on the exterior, with an abundance of
gables and balconies. It is set in an environment of woods and sweeps of
lawn, flanked by unusually large conservatories, and always bright in
summer with glowing flower beds. It would be difficult to imagine Edison
in a stiffly formal house, and this big, cozy, three-story, rambling mansion
has an easy freedom about it, without and within, quite in keeping with the
genius of the inventor, but revealing at every turn traces of feminine taste
and culture. The ground floor, consisting chiefly of broad drawing-rooms,
parlors, and dining-hall, is chiefly noteworthy for the "den," or lounging-
room, at the end of the main axis, where the family and friends are likely to
be found in the evening hours, unless the party has withdrawn for more
intimate social intercourse to the interesting and fascinating private library
on the floor above. The lounging-room on the ground floor is more or less
of an Edison museum, for it is littered with souvenirs from great people,
and with mementos of travel, all related to some event or episode. A large
cabinet contains awards, decorations, and medals presented to Edison,
accumulating in the course of a long career, some of which may be seen in
the illustration opposite. Near by may be noticed a bronze replica of the
Edison gold medal which was founded in the American Institute of
Electrical Engineers, the first award of which was made to Elihu Thomson
during the present year (1910). There are statues of serpentine marble, gifts
of the late Tsar of Russia, whose admiration is also represented by a
gorgeous inlaid and enamelled cigar-case.
There are typical bronze vases from the Society of Engineers of Japan,
and a striking desk-set of writing apparatus from Krupp, all the pieces being
made out of tiny but massive guns and shells of Krupp steel. In addition to
such bric-a-brac and bibelots of all kinds are many pictures and
photographs, including the original sketches of the reception given to
Edison in 1889 by the Paris Figaro, and a letter from Madame Carnot,
placing the Presidential opera-box at the disposal of Mr. and Mrs. Edison.

One of the most conspicuous features of the room is a phonograph
equipment on which the latest and best productions by the greatest singers
and musicians can always be heard, but which Edison himself is
everlastingly experimenting with, under the incurable delusion that this
domestic retreat is but an extension of his laboratory.
The big library—semi-boudoir—up-stairs is also very expressive of the
home life of Edison, but again typical of his nature and disposition, for it is
difficult to overlay his many technical books and scientific periodicals with
a sufficiently thick crust of popular magazines or current literature to
prevent their outcropping into evidence. In like manner the chat and
conversation here, however lightly it may begin, turns invariably to large
questions and deep problems, especially in the fields of discovery and
invention; and Edison, in an easy-chair, will sit through the long evenings
till one or two in the morning, pulling meditatively at his eyebrows, quoting
something he has just read pertinent to the discussion, hearing and telling
new stories with gusto, offering all kinds of ingenious suggestions, and
without fail getting hold of pads and sheets of paper on which to make
illustrative sketches. He is wonderfully handy with the pencil, and will
sometimes amuse himself, while chatting, with making all kinds of fancy
bits of penmanship, twisting his signature into circles and squares, but
always writing straight lines—so straight they could not be ruled truer.
Many a night it is a question of getting Edison to bed, for he would much
rather probe a problem than eat or sleep; but at whatever hour the visitor
retires or gets up, he is sure to find the master of the house on hand, serene
and reposeful, and just as brisk at dawn as when he allowed the
conversation to break up at midnight. The ordinary routine of daily family
life is of course often interrupted by receptions and parties, visits to the
billiard-room, the entertainment of visitors, the departure to and return from
college, at vacation periods, of the young people, and matters relating to the
many social and philanthropic causes in which Mrs. Edison is actively
interested; but, as a matter of fact, Edison's round of toil and relaxation is
singularly uniform and free from agitation, and that is the way he would
rather have it.
Edison at sixty-three has a fine physique, and being free from serious
ailments of any kind, should carry on the traditions of his long-lived
ancestors as to a vigorous old age. His hair has whitened, but is still thick
and abundant, and though he uses glasses for certain work, his gray-blue

Page 509
eyes are as keen and bright and deeply lustrous as ever, with the direct,
searching look in them that they have ever worn. He stands five feet nine
and one-half inches high, weighs one hundred and seventy-five pounds, and
has not varied as to weight in a quarter of a century, although as a young
man he was slim to gauntness. He is very abstemious, hardly ever touching
alcohol, caring little for meat, but fond of fruit, and never averse to a strong
cup of coffee or a good cigar. He takes extremely little exercise, although
his good color and quickness of step would suggest to those who do not
know better that he is in the best of training, and one who lives in the open
air.
His simplicity as to clothes has already been described. One would be
startled to see him with a bright tie, a loud checked suit, or a fancy
waistcoat, and yet there is a curious sense of fastidiousness about the plain
things he delights in. Perhaps he is not wholly responsible personally for
this state of affairs. In conversation Edison is direct, courteous, ready to
discuss a topic with anybody worth talking to, and, in spite of his sore
deafness, an excellent listener. No one ever goes away from Edison in doubt
as to what he thinks or means, but he is ever shy and diffident to a degree if
the talk turns on himself rather than on his work.
If the authors were asked, after having written the foregoing pages, to
explain here the reason for Edison's success, based upon their observations
so far made, they would first answer that he combines with a vigorous and
normal physical structure a mind capable of clear and logical thinking, and
an imagination of unusual activity. But this would by no means offer a
complete explanation. There are many men of equal bodily and mental
vigor who have not achieved a tithe of his accomplishment. What other
factors are there to be taken into consideration to explain this phenomenon?
First, a stolid, almost phlegmatic, nervous system which takes absolutely no
notice of ennui—a system like that of a Chinese ivory-carver who works
day after day and month after month on a piece of material no larger than
your hand. No better illustration of this characteristic can be found than in
the development of the nickel pocket for the storage battery, an element the
size of a short lead-pencil, on which upward of five years were spent in
experiments, costing over a million dollars, day after day, always apparently
with the same tubes but with small variations carefully tabulated in the
note-books. To an ordinary person the mere sight of such a tube would have
been as distasteful, certainly after a week or so, as the smell of a quail to a
searching look in them that they have ever worn. He stands five feet nine

Page 510
man striving to eat one every day for a month, near the end of his
gastronomic ordeal. But to Edison these small perforated steel tubes held
out as much of a fascination at the end of five years as when the search was
first begun, and every morning found him as eager to begin the
investigation anew as if the battery was an absolutely novel problem to
which his thoughts had just been directed.
Another and second characteristic of Edison's personality contributing so
strongly to his achievements is an intense, not to say courageous, optimism
in which no thought of failure can enter, an optimism born of self-
confidence, and becoming—after forty or fifty years of experience more
and more a sense of certainty in the accomplishment of success. In the
overcoming of difficulties he has the same intellectual pleasure as the
chess-master when confronted with a problem requiring all the efforts of his
skill and experience to solve. To advance along smooth and pleasant paths,
to encounter no obstacles, to wrestle with no difficulties and hardships—
such has absolutely no fascination to him. He meets obstruction with the
keen delight of a strong man battling with the waves and opposing them in
sheer enjoyment, and the greater and more apparently overwhelming the
forces that may tend to sweep him back, the more vigorous his own efforts
to forge through them. At the conclusion of the ore-milling experiments,
when practically his entire fortune was sunk in an enterprise that had to be
considered an impossibility, when at the age of fifty he looked back upon
five or six years of intense activity expended apparently for naught, when
everything seemed most black and the financial clouds were quickly
gathering on the horizon, not the slightest idea of repining entered his mind.
The main experiment had succeeded—he had accomplished what he sought
for. Nature at another point had outstripped him, yet he had broadened his
own sum of knowledge to a prodigious extent. It was only during the past
summer (1910) that one of the writers spent a Sunday with him riding over
the beautiful New Jersey roads in an automobile, Edison in the highest
spirits and pointing out with the keenest enjoyment the many beautiful
views of valley and wood. The wanderings led to the old ore-milling plant
at Edison, now practically a mass of deserted buildings all going to decay. It
was a depressing sight, marking such titanic but futile struggles with nature.

ruins were apparently as much a matter of unconcern as if he were viewing
the remains of Pompeii. Sitting on the porch of the White House, where he

ruins were apparently as much a matter of unconcern as if he were viewing

Page 511
lived during that period, in the light of the setting sun, his fine face in
repose, he looked as placidly over the scene as a happy farmer over a field
of ripening corn. All that he said was: "I never felt better in my life than
during the five years I worked here. Hard work, nothing to divert my
thought, clear air and simple food made my life very pleasant. We learned a
great deal. It will be of benefit to some one some time." Similarly, in
connection with the storage battery, after having experimented continuously
for three years, it was found to fall below his expectations, and its
manufacture had to be stopped. Hundreds of thousands of dollars had been
spent on the experiments, and, largely without Edison's consent, the battery
had been very generally exploited in the press. To stop meant not only to
pocket a great loss already incurred, facing a dark and uncertain future, but
to most men animated by ordinary human feelings, it meant more than
anything else, an injury to personal pride. Pride? Pooh! that had nothing to
do with the really serious practical problem, and the writers can testify that
at the moment when his decision was reached, work stopped and the long
vista ahead was peered into, Edison was as little concerned as if he had
concluded that, after all, perhaps peach-pie might be better for present diet
than apple-pie. He has often said that time meant very little to him, that he
had but a small realization of its passage, and that ten or twenty years were
as nothing when considering the development of a vital invention.
These references to personal pride recall another characteristic of Edison
wherein he differs from most men. There are many individuals who derive
an intense and not improper pleasure in regalia or military garments, with
plenty of gold braid and brass buttons, and thus arrayed, in appearing before
their friends and neighbors. Putting at the head of the procession the man
who makes his appeal to public attention solely because of the brilliancy of
his plumage, and passing down the ranks through the multitudes having a
gradually decreasing sense of vanity in their personal accomplishment,
Edison would be placed at the very end. Reference herein has been made to
the fact that one of the two great English universities wished to confer a
degree upon him, but that he was unable to leave his work for the brief time
necessary to accept the honor. At that occasion it was pointed out to him
that he should make every possible sacrifice to go, that the compliment was
great, and that but few Americans had been so recognized. It was hopeless
—an appeal based on sentiment. Before him was something real—work to
be accomplished—a problem to be solved. Beyond, was a prize as
repose, he looked as placidly over the scene as a happy farmer over a field
of ripening corn. All that he said was: "I never felt better in my life than
during the five years I worked here. Hard work, nothing to divert my
thought, clear air and simple food made my life very pleasant. We learned a
great deal. It will be of benefit to some one some time." Similarly, in
connection with the storage battery, after having experimented continuously
for three years, it was found to fall below his expectations, and its
manufacture had to be stopped. Hundreds of thousands of dollars had been
spent on the experiments, and, largely without Edison's consent, the battery
had been very generally exploited in the press. To stop meant not only to
pocket a great loss already incurred, facing a dark and uncertain future, but
to most men animated by ordinary human feelings, it meant more than
anything else, an injury to personal pride. Pride? Pooh! that had nothing to
do with the really serious practical problem, and the writers can testify that
at the moment when his decision was reached, work stopped and the long
vista ahead was peered into, Edison was as little concerned as if he had
concluded that, after all, perhaps peach-pie might be better for present diet
than apple-pie. He has often said that time meant very little to him, that he
had but a small realization of its passage, and that ten or twenty years were
as nothing when considering the development of a vital invention.

Page 512
intangible as the button of the Legion of Honor, which he concealed from
his friends that they might not feel he was "showing off." The fact is that
Edison cares little for the approval of the world, but that he cares everything
for the approval of himself. Difficult as it may be—perhaps impossible—to
trace its origin, Edison possesses what he would probably call a well-
developed case of New England conscience, for whose approval he is
incessantly occupied.
These, then, may be taken as the characteristics of Edison that have
enabled him to accomplish more than most men—a strong body, a clear and
active mind, a developed imagination, a capacity of great mental and
physical concentration, an iron-clad nervous system that knows no ennui,
intense optimism, and courageous self-confidence. Any one having these
capacities developed to the same extent, with the same opportunities for
use, would probably accomplish as much. And yet there is a peculiarity
about him that so far as is known has never been referred to before in print.
He seems to be conscientiously afraid of appearing indolent, and in
consequence subjects himself regularly to unnecessary hardship. Working
all night is seldom necessary, or until two or three o'clock in the morning,
yet even now he persists in such tests upon his strength. Recently one of the
writers had occasion to present to him a long typewritten document of
upward of thirty pages for his approval. It was taken home to Glenmont.
Edison had a few minor corrections to make, probably not more than a
dozen all told. They could have been embodied by interlineations and
marginal notes in the ordinary way, and certainly would not have required
more than ten or fifteen minutes of his time. Yet what did he do? HE
COPIED OUT PAINSTAKINGLY THE ENTIRE PAPER IN LONG
HAND, embodying the corrections as he went along, and presented the
result of his work the following morning. At the very least such a task must
have occupied several hours. How can such a trait—and scores of similar
experiences could be given—be explained except by the fact that, evidently,
he felt the need of special schooling in industry—that under no
circumstances must he allow a thought of indolence to enter his mind?
Undoubtedly in the days to come Edison will not only be recognized as
an intellectual prodigy, but as a prodigy of industry—of hard work. In his
field as inventor and man of science he stands as clear-cut and secure as the
lighthouse on a rock, and as indifferent to the tumult around. But as the "old
man"—and before he was thirty years old he was affectionately so called by
his friends that they might not feel he was "showing off." The fact is that

man"—and before he was thirty years old he was affectionately so called by
Page 513
his laboratory associates—he is a normal, fun-loving, typical American. His
sense of humor is intense, but not of the hothouse, overdeveloped variety.
One of his favorite jokes is to enter the legal department with an air of great
humility and apply for a job as an inventor! Never is he so preoccupied or
fretted with cares as not to drop all thought of his work for a few moments
to listen to a new story, with a ready smile all the while, and a hearty,
boyish laugh at the end. His laugh, in fact, is sometimes almost aboriginal;
slapping his hands delightedly on his knees, he rocks back and forth and
fairly shouts his pleasure. Recently a daily report of one of his companies
that had just been started contained a large order amounting to several
thousand dollars, and was returned by him with a miniature sketch of a
small individual viewing that particular item through a telescope! His
facility in making hasty but intensely graphic sketches is proverbial. He
takes great delight in imitating the lingo of the New York street gamin. A
dignified person named James may be greeted with: "Hully Gee! Chimmy,
when did youse blow in?" He likes to mimic and imitate types, generally,
that are distasteful to him. The sanctimonious hypocrite, the sleek
speculator, and others whom he has probably encountered in life are done
"to the queen's taste."
One very cold winter's day he entered the laboratory library in fine
spirits, "doing" the decayed dandy, with imaginary cane under his arm,
struggling to put on a pair of tattered imaginary gloves, with a self-satisfied
smirk and leer that would have done credit to a real comedian. This
particular bit of acting was heightened by the fact that even in the coldest
weather he wears thin summer clothes, generally acid-worn and more or
less disreputable. For protection he varies the number of his suits of
underclothing, sometimes wearing three or four sets, according to the
thermometer.
If one could divorce Edison from the idea of work, and could regard him
separate and apart from his embodiment as an inventor and man of science,
it might truly be asserted that his temperament is essentially mercurial.
Often he is in the highest spirits, with all the spontaneity of youth, and
again he is depressed, moody, and violently angry. Anger with him,
however, is a good deal like the story attributed to Napoleon:
"Sire, how is it that your judgment is not affected by your great rage?"
asked one of his courtiers.

"Because," said the Emperor, "I never allow it to rise above this line,"
drawing his hand across his throat. Edison has been seen sometimes almost
beside himself with anger at a stupid mistake or inexcusable oversight on
the part of an assistant, his voice raised to a high pitch, sneeringly
expressing his feelings of contempt for the offender; and yet when the
culprit, like a bad school-boy, has left the room, Edison has immediately
returned to his normal poise, and the incident is a thing of the past. At other
times the unsettled condition persists, and his spleen is vented not only on
the original instigator but upon others who may have occasion to see him,
sometimes hours afterward. When such a fit is on him the word is quickly
passed around, and but few of his associates find it necessary to consult
with him at the time. The genuine anger can generally be distinguished
from the imitation article by those who know him intimately by the fact that
when really enraged his forehead between the eyes partakes of a curious
rotary movement that cannot be adequately described in words. It is as if
the storm-clouds within are moving like a whirling cyclone. As a general
rule, Edison does not get genuinely angry at mistakes and other human
weaknesses of his subordinates; at best he merely simulates anger. But woe
betide the one who has committed an act of bad faith, treachery, dishonesty,
or ingratitude; THEN Edison can show what it is for a strong man to get
downright mad. But in this respect he is singularly free, and his spells of
anger are really few. In fact, those who know him best are continually
surprised at his moderation and patience, often when there has been great
provocation. People who come in contact with him and who may have
occasion to oppose his views, may leave with the impression that he is hot-
tempered; nothing could be further from the truth. He argues his point with
great vehemence, pounds on the table to emphasize his views, and
illustrates his theme with a wealth of apt similes; but, on account of his
deafness, it is difficult to make the argument really two-sided. Before the
visitor can fully explain his side of the matter some point is brought up that
starts Edison off again, and new arguments from his viewpoint are poured
forth. This constant interruption is taken by many to mean that Edison has a
small opinion of any arguments that oppose him; but he is only intensely in
earnest in presenting his own side. If the visitor persists until Edison has
seen both sides of the controversy, he is always willing to frankly admit that
his own views may be unsound and that his opponent is right. In fact, after
such a controversy, both parties going after each other hammer and tongs,
drawing his hand across his throat. Edison has been seen sometimes almost

INTRODUCTION TO THE APPENDIX
THE reader who has followed the foregoing narrative may feel that
inasmuch as it is intended to be an historical document, an appropriate
addendum thereto would be a digest of all the inventions of Edison. The
desirability of such a digest is not to be denied, but as there are some
twenty-five hundred or more inventions to be considered (including those
covered by caveats), the task of its preparation would be stupendous.
Besides, the resultant data would extend this book into several additional
volumes, thereby rendering it of value chiefly to the technical student, but
taking it beyond the bounds of biography.
We should, however, deem our presentation of Mr. Edison's work to be
imperfectly executed if we neglected to include an intelligible exposition of
the broader theoretical principles of his more important inventions. In the
following Appendix we have therefore endeavored to present a few brief
statements regarding Mr. Edison's principal inventions, classified as to
subject-matter and explained in language as free from technicalities as is
possible. No attempt has been made to conform with strictly scientific
terminology, but, for the benefit of the general reader, well-understood
conventional expressions, such as "flow of current," etc., have been
employed. It should be borne in mind that each of the following items has
been treated as a whole or class, generally speaking, and not as a digest of
all the individual patents relating to it. Any one who is sufficiently
interested can obtain copies of any of the patents referred to for five cents
each by addressing the Commissioner of Patents, Washington, D. C.

I. THE STOCK PRINTER
IN these modern days, when the Stock Ticker is in universal use, one
seldom, if ever, hears the name of Edison coupled with the little instrument
whose chatterings have such tremendous import to the whole world. It is of
much interest, however, to remember the fact that it was by reason of his
notable work in connection with this device that he first became known as
an inventor. Indeed, it was through the intrinsic merits of his improvements
in stock tickers that he made his real entree into commercial life.
The idea of the ticker did not originate with Edison, as we have already
seen in Chapter VII of the preceding narrative, but at the time of his
employment with the Western Union, in Boston, in 1868, the crudities of
the earlier forms made an impression on his practical mind, and he got out
an improved instrument of his own, which he introduced in Boston through
the aid of a professional promoter. Edison, then only twenty-one, had less
business experience than the promoter, through whose manipulation he
soon lost his financial interest in this early ticker enterprise. The narrative
tells of his coming to New York in 1869, and immediately plunging into the
business of gold and stock reporting. It was at this period that his real work
on stock printers commenced, first individually, and later as a co-worker
with F. L. Pope. This inventive period extended over a number of years,
during which time he took out forty-six patents on stock-printing
instruments and devices, two of such patents being issued to Edison and
Pope as joint inventors. These various inventions were mostly in the line of
development of the art as it progressed during those early years, but out of it
all came the Edison universal printer, which entered into very extensive use,
and which is still used throughout the United States and in some foreign
countries to a considerable extent at this very day.
Edison's inventive work on stock printers has left its mark upon the art as
it exists at the present time. In his earlier work he directed his attention to
the employment of a single-circuit system, in which only one wire was
required, the two operations of setting the type-wheels and of printing being
controlled by separate electromagnets which were actuated through
polarized relays, as occasion required, one polarity energizing the

development of the art as it progressed during those early years, but out of it
all came the Edison universal printer, which entered into very extensive use,
and which is still used throughout the United States and in some foreign
countries to a considerable extent at this very day.
Edison's inventive work on stock printers has left its mark upon the art as
it exists at the present time. In his earlier work he directed his attention to
the employment of a single-circuit system, in which only one wire was
required, the two operations of setting the type-wheels and of printing being
controlled by separate electromagnets which were actuated through
polarized relays, as occasion required, one polarity energizing the
Page 520
electromagnet controlling the type-wheels, and the opposite polarity
energizing the electromagnet controlling the printing. Later on, however, he
changed over to a two-wire circuit, such as shown in Fig. 2 of this article in
connection with the universal stock printer. In the earliest days of the stock
printer, Edison realized the vital commercial importance of having all
instruments recording precisely alike at the same moment, and it was he
who first devised (in 1869) the "unison stop," by means of which all
connected instruments could at any moment be brought to zero from the
central transmitting station, and thus be made to work in correspondence
with the central instrument and with one another. He also originated the
idea of using only one inking-pad and shifting it from side to side to ink the
type-wheels. It was also in Edison's stock printer that the principle of
shifting type-wheels was first employed. Hence it will be seen that, as in
many other arts, he made a lasting impression in this one by the intrinsic
merits of the improvements resulting from his work therein.
We shall not attempt to digest the forty-six patents above named, nor to
follow Edison through the progressive steps which led to the completion of
his universal printer, but shall simply present a sketch of the instrument
itself, and follow with a very brief and general explanation of its theory.
The Edison universal printer, as it virtually appears in practice, is illustrated
in Fig. 1 below, from which it will be seen that the most prominent parts are
the two type-wheels, the inking-pad, and the paper tape feeding from the
reel, all appropriately placed in a substantial framework.
The electromagnets and other actuating mechanism cannot be seen
plainly in this figure, but are produced diagrammatically in Fig. 2, and
somewhat enlarged for convenience of explanation.
It will be seen that there are two electromagnets, one of which, TM, is
known as the "type-magnet," and the other, PM, as the "press-magnet," the
former having to do with the operation of the type-wheels, and the latter
with the pressing of the paper tape against them. As will be seen from the
diagram, the armature, A, of the type-magnet has an extension arm, on the
end of which is an escapement engaging with a toothed wheel placed at the
extremity of the shaft carrying the type-wheels. This extension arm is
pivoted at B. Hence, as the armature is alternately attracted when current
passes around its electromagnet, and drawn up by the spring on cessation of
current, it moves up and down, thus actuating the escapement and causing a
energizing the electromagnet controlling the printing. Later on, however, he
changed over to a two-wire circuit, such as shown in Fig. 2 of this article in
connection with the universal stock printer. In the earliest days of the stock
printer, Edison realized the vital commercial importance of having all

passes around its electromagnet, and drawn up by the spring on cessation of
current, it moves up and down, thus actuating the escapement and causing a
Page 521
rotation of the toothed wheel in the direction of the arrow. This, in turn,
brings any desired letters or figures on the type-wheels to a central point,
where they may be impressed upon the paper tape. One type-wheel carries
letters, and the other one figures. These two wheels are mounted rigidly on
a sleeve carried by the wheel-shaft. As it is desired to print from only one
type-wheel at a time, it becomes necessary to shift them back and forth
from time to time, in order to bring the desired characters in line with the
paper tape. This is accomplished through the movements of a three-arm
rocking-lever attached to the wheel-sleeve at the end of the shaft. This lever
is actuated through the agency of two small pins carried by an arm
projecting from the press-lever, PL. As the latter moves up and down the
pins play upon the under side of the lower arm of the rocking-lever, thus
canting it and pushing the type-wheels to the right or left, as the case may
be. The operation of shifting the type-wheels will be given further on.
The press-lever is actuated by the press-magnet. From the diagram it will
be seen that the armature of the latter has a long, pivoted extension arm, or
platen, trough-like in shape, in which the paper tape runs. It has already
been noted that the object of the press-lever is to press this tape against that
character of the type-wheel centrally located above it at the moment. It will
at once be perceived that this action takes place when current flows through
the electromagnet and its armature is attracted downward, the platen again
dropping away from the type-wheel as the armature is released upon
cessation of current. The paper "feed" is shown at the end of the press-lever,
and consists of a push "dog," or pawl, which operates to urge the paper
forward as the press-lever descends.
The worm-gear which appears in the diagram on the shaft, near the
toothed wheel, forms part of the unison stop above referred to, but this
device is not shown in full, in order to avoid unnecessary complications of
the drawing.
At the right-hand side of the diagram (Fig. 2) is shown a portion of the
transmitting apparatus at a central office. Generally speaking, this consists
of a motor-driven cylinder having metallic pins placed at intervals, and
arranged spirally, around its periphery. These pins correspond in number to
the characters on the type-wheels. A keyboard (not shown) is arranged
above the cylinder, having keys lettered and numbered corresponding to the
letters and figures on the type-wheels. Upon depressing any one of these
brings any desired letters or figures on the type-wheels to a central point,
where they may be impressed upon the paper tape. One type-wheel carries
letters, and the other one figures. These two wheels are mounted rigidly on
a sleeve carried by the wheel-shaft. As it is desired to print from only one
type-wheel at a time, it becomes necessary to shift them back and forth
from time to time, in order to bring the desired characters in line with the
paper tape. This is accomplished through the movements of a three-arm
rocking-lever attached to the wheel-sleeve at the end of the shaft. This lever
is actuated through the agency of two small pins carried by an arm
projecting from the press-lever, PL. As the latter moves up and down the
pins play upon the under side of the lower arm of the rocking-lever, thus
canting it and pushing the type-wheels to the right or left, as the case may

of a motor-driven cylinder having metallic pins placed at intervals, and
arranged spirally, around its periphery. These pins correspond in number to
the characters on the type-wheels. A keyboard (not shown) is arranged
above the cylinder, having keys lettered and numbered corresponding to the
letters and figures on the type-wheels. Upon depressing any one of these
Page 522
keys the motion of the cylinder is arrested when one of its pins is caught
and held by the depressed key. When the key is released the cylinder
continues in motion. Hence, it is evident that the revolution of the cylinder
may be interrupted as often as desired by manipulation of the various keys
in transmitting the letters and figures which are to be recorded by the
printing instrument. The method of transmission will presently appear.
In the sketch (Fig. 2) there will be seen, mounted upon the cylinder shaft,
two wheels made up of metallic segments insulated from each other, and
upon the hubs of these wheels are two brushes which connect with the main
battery. Resting upon the periphery of these two segmental wheels there are
two brushes to which are connected the wires which carry the battery
current to the type-magnet and press-magnet, respectively, as the brushes
make circuit by coming in contact with the metallic segments. It will be
remembered that upon the cylinder there are as many pins as there are
characters on the type-wheels of the ticker, and one of the segmental
wheels, W, has a like number of metallic segments, while upon the other
wheel, W', there are only one-half that number. The wheel W controls the
supply of current to the press-magnet, and the wheel W' to the type-magnet.
The type-magnet advances the letter and figure wheels one step when the
magnet is energized, and a succeeding step when the circuit is broken.
Hence, the metallic contact surfaces on wheel W' are, as stated, only half as
many as on the wheel W, which controls the press-magnet.
It should be borne in mind, however, that the contact surfaces and
insulated surfaces on wheel W' are together equal in number to the
characters on the type-wheels, but the retractile spring of TM does half the
work of operating the escapement. On the other hand, the wheel W has the
full number of contact surfaces, because it must provide for the operative
closure of the press-magnet circuit whether the brush B' is in engagement
with a metallic segment or an insulated segment of the wheel W'. As the
cylinder revolves, the wheels are carried around with its shaft and current
impulses flow through the wires to the magnets as the brushes make contact
with the metallic segments of these wheels.
One example will be sufficient to convey to the reader an idea of the
operation of the apparatus. Assuming, for instance, that it is desired to send
out the letters AM to the printer, let us suppose that the pin corresponding to
the letter A is at one end of the cylinder and near the upper part of its
and held by the depressed key. When the key is released the cylinder
continues in motion. Hence, it is evident that the revolution of the cylinder
may be interrupted as often as desired by manipulation of the various keys
in transmitting the letters and figures which are to be recorded by the
printing instrument. The method of transmission will presently appear.

operation of the apparatus. Assuming, for instance, that it is desired to send
out the letters AM to the printer, let us suppose that the pin corresponding to
the letter A is at one end of the cylinder and near the upper part of its
Page 523
periphery, and that the letter M is about the centre of the cylinder and near
the lower part of its periphery. The operator at the keyboard would depress
the letter A, whereupon the cylinder would in its revolution bring the first-
named pin against the key. During the rotation of the cylinder a current
would pass through wheel W' and actuate TM, drawing down the armature
and operating the escapement, which would bring the type-wheel to a point
where the letter A would be central as regards the paper tape When the
cylinder came to rest, current would flow through the brush of wheel W to
PM, and its armature would be attracted, causing the platen to be lifted and
thus bringing the paper tape in contact with the type-wheel and printing the
letter A. The operator next sends the letter M by depressing the appropriate
key. On account of the position of the corresponding pin, the cylinder
would make nearly half a revolution before bringing the pin to the key.
During this half revolution the segmental wheels have also been turning,
and the brushes have transmitted a number of current impulses to TM,
which have caused it to operate the escapement a corresponding number of
times, thus turning the type-wheels around to the letter M. When the
cylinder stops, current once more goes to the press-magnet, and the
operation of lifting and printing is repeated. As a matter of fact, current
flows over both circuits as the cylinder is rotated, but the press-magnet is
purposely made to be comparatively "sluggish" and the narrowness of the
segments on wheel W tends to diminish the flow of current in the press
circuit until the cylinder comes to rest, when the current continuously flows
over that circuit without interruption and fully energizes the press-magnet.
The shifting of the type-wheels is brought about as follows: On the
keyboard of the transmitter there are two characters known as "dots"—
namely, the letter dot and the figure dot. If the operator presses one of these
dot keys, it is engaged by an appropriate pin on the revolving cylinder.
Meanwhile the type-wheels are rotating, carrying with them the rocking-
lever, and current is pulsating over both circuits. When the type-wheels
have arrived at the proper point the rocking-lever has been carried to a
position where its lower arm is directly over one of the pins on the arm
extending from the platen of the press-lever. The cylinder stops, and current
operates the sluggish press-magnet, causing its armature to be attracted,
thus lifting the platen and its projecting arm. As the arm lifts upward, the
pin moves along the under side of the lower arm of the rocking-lever, thus
causing it to cant and shift the type-wheels to the right or left, as desired.

II. THE QUADRUPLEX AND PHONOPLEX
EDISON'S work in stock printers and telegraphy had marked him as a
rising man in the electrical art of the period but his invention of quadruplex
telegraphy in 1874 was what brought him very prominently before the
notice of the public. Duplex telegraphy, or the sending of two separate
messages in opposite directions at the same time over one line was known
and practiced previous to this time, but quadruplex telegraphy, or the
simultaneous sending of four separate messages, two in each direction, over
a single line had not been successfully accomplished, although it had been
the subject of many an inventor's dream and the object of anxious efforts for
many long years.
In the early part of 1873, and for some time afterward, the system
invented by Joseph Stearns was the duplex in practical use. In April of that
year, however, Edison took up the study of the subject and filed two
applications for patents. One of these applications [23] embraced an
invention by which two messages could be sent not only duplex, or in
opposite directions as above explained, but could also be sent "diplex"—
that is to say, in one direction, simultaneously, as separate and distinct
messages, over the one line. Thus there was introduced a new feature into
the art of multiplex telegraphy, for, whereas duplexing (accomplished by
varying the strength of the current) permitted messages to be sent
simultaneously from opposite stations, diplexing (achieved by also varying
the direction of the current) permitted the simultaneous transmission of two
messages from the same station and their separate reception at the distant
station.
[Footnote 23: Afterward issued as Patent No. 162,633, April
27, 1875.]
The quadruplex was the tempting goal toward which Edison now
constantly turned, and after more than a year's strenuous work he filed a
number of applications for patents in the late summer of 1874. Among them
was one which was issued some years afterward as Patent No. 480,567,
covering his well-known quadruplex. He had improved his own diplex,

combined it with the Stearns duplex and thereby produced a system by
means of which four messages could be sent over a single line at the same
time, two in each direction.
As the reader will probably be interested to learn something of the
theoretical principles of this fascinating invention, we shall endeavor to
offer a brief and condensed explanation thereof with as little technicality as
the subject will permit. This explanation will necessarily be of somewhat
elementary character for the benefit of the lay reader, whose indulgence is
asked for an occasional reiteration introduced for the sake of clearness of
comprehension. While the apparatus and the circuits are seemingly very
intricate, the principles are really quite simple, and the difficulty of
comprehension is more apparent than real if the underlying phenomena are
studied attentively.
At the root of all systems of telegraphy, including multiplex systems,
there lies the single basic principle upon which their performance depends
—namely, the obtaining of a slight mechanical movement at the more or
less distant end of a telegraph line. This is accomplished through the
utilization of the phenomena of electromagnetism. These phenomena are
easy of comprehension and demonstration. If a rod of soft iron be wound
around with a number of turns of insulated wire, and a current of electricity
be sent through the wire, the rod will be instantly magnetized and will
remain a magnet as long as the current flows; but when the current is cut off
the magnetic effect instantly ceases. This device is known as an
electromagnet, and the charging and discharging of such a magnet may, of
course, be repeated indefinitely. Inasmuch as a magnet has the power of
attracting to itself pieces of iron or steel, the basic importance of an
electromagnet in telegraphy will be at once apparent when we consider the
sounder, whose clicks are familiar to every ear. This instrument consists
essentially of an electro-magnet of horseshoe form with its two poles close
together, and with its armature, a bar of iron, maintained in close proximity
to the poles, but kept normally in a retracted position by a spring. When the
distant operator presses down his key the circuit is closed and a current
passes along the line and through the (generally two) coils of the
electromagnet, thus magnetizing the iron core. Its attractive power draws
the armature toward the poles. When the operator releases the pressure on
his key the circuit is broken, current does not flow, the magnetic effect
ceases, and the armature is drawn back by its spring. These movements give
means of which four messages could be sent over a single line at the same
time, two in each direction.

the armature toward the poles. When the operator releases the pressure on
his key the circuit is broken, current does not flow, the magnetic effect
ceases, and the armature is drawn back by its spring. These movements give
Page 527
rise to the clicking sounds which represent the dots and dashes of the Morse
or other alphabet as transmitted by the operator. Similar movements,
produced in like manner, are availed of in another instrument known as the
relay, whose office is to act practically as an automatic transmitter key,
repeating the messages received in its coils, and sending them on to the next
section of the line, equipped with its own battery; or, when the message is
intended for its own station, sending the message to an adjacent sounder
included in a local battery circuit. With a simple circuit, therefore, between
two stations and where an intermediate battery is not necessary, a relay is
not used.
Passing on to the consideration of another phase of the phenomena of
electromagnetism, the reader's attention is called to Fig. 1, in which will be
seen on the left a simple form of electromagnet consisting of a bar of soft
iron wound around with insulated wire, through which a current is flowing
from a battery. The arrows indicate the direction of flow.
All magnets have two poles, north and south. A permanent magnet (made
of steel, which, as distinguished from soft iron, retains its magnetism for
long periods) is so called because it is permanently magnetized and its
polarity remains fixed. In an electromagnet the magnetism exists only as
long as current is flowing through the wire, and the polarity of the soft-iron
bar is determined by the DIRECTION of flow of current around it for the
time being. If the direction is reversed, the polarity will also be reversed.
Assuming, for instance, the bar to be end-on toward the observer, that end
will be a south pole if the current is flowing from left to right, clockwise,
around the bar; or a north pole if flowing in the other direction, as
illustrated at the right of the figure. It is immaterial which way the wire is
wound around the bar, the determining factor of polarity being the
DIRECTION of the current. It will be clear, therefore, that if two EQUAL
currents be passed around a bar in opposite directions (Fig. 3) they will tend
to produce exactly opposite polarities and thus neutralize each other. Hence,
the bar would remain non-magnetic.
As the path to the quadruplex passes through the duplex, let us consider
the Stearns system, after noting one other principle—namely, that if more
than one path is presented in which an electric current may complete its
circuit, it divides in proportion to the resistance of each path. Hence, if we
connect one pole of a battery with the earth, and from the other pole run to
or other alphabet as transmitted by the operator. Similar movements,
produced in like manner, are availed of in another instrument known as the
relay, whose office is to act practically as an automatic transmitter key,
repeating the messages received in its coils, and sending them on to the next
section of the line, equipped with its own battery; or, when the message is
intended for its own station, sending the message to an adjacent sounder
included in a local battery circuit. With a simple circuit, therefore, between
two stations and where an intermediate battery is not necessary, a relay is
not used.

will be a south pole if the current is flowing from left to right, clockwise,
around the bar; or a north pole if flowing in the other direction, as
illustrated at the right of the figure. It is immaterial which way the wire is
wound around the bar, the determining factor of polarity being the
DIRECTION of the current. It will be clear, therefore, that if two EQUAL
currents be passed around a bar in opposite directions (Fig. 3) they will tend

As the path to the quadruplex passes through the duplex, let us consider
the Stearns system, after noting one other principle—namely, that if more
than one path is presented in which an electric current may complete its
circuit, it divides in proportion to the resistance of each path. Hence, if we
connect one pole of a battery with the earth, and from the other pole run to
Page 528
the earth two wires of equal resistance as illustrated in Fig. 2, equal currents
will traverse the wires.
The above principles were employed in the Stearns differential duplex
system in the following manner: Referring to Fig. 3, suppose a wire, A, is
led from a battery around a bar of soft iron from left to right, and another
wire of equal resistance and equal number of turns, B, around from right to
left. The flow of current will cause two equal opposing actions to be set up
in the bar; one will exactly offset the other, and no magnetic effect will be
produced. A relay thus wound is known as a differential relay—more
generally called a neutral relay.
The non-technical reader may wonder what use can possibly be made of
an apparently non-operative piece of apparatus. It must be borne in mind,
however, in considering a duplex system, that a differential relay is used AT
EACH END of the line and forms part of the circuit; and that while each
relay must be absolutely unresponsive to the signals SENT OUT FROM
ITS HOME OFFICE, it must respond to signals transmitted by a DISTANT
OFFICE. Hence, the next figure (4), with its accompanying explanation,
will probably make the matter clear. If another battery, D, be introduced at
the distant end of the wire A the differential or neutral relay becomes
actively operative as follows: Battery C supplies wires A and B with an
equal current, but battery D doubles the strength of the current traversing
wire A. This is sufficient to not only neutralize the magnetism which the
current in wire B would tend to set up, but also—by reason of the excess of
current in wire A—to make the bar a magnet whose polarity would be
determined by the direction of the flow of current around it.
In the arrangement shown in Fig. 4 the batteries are so connected that
current flow is in the same direction, thus doubling the amount of current
flowing through wire A. But suppose the batteries were so connected that
the current from each set flowed in an opposite direction? The result would
be that these currents would oppose and neutralize each other, and,
therefore, none would flow in wire A. Inasmuch, however, as there is
nothing to hinder, current would flow from battery C through wire B, and
the bar would therefore be magnetized. Hence, assuming that the relay is to
be actuated from the distant end, D, it is in a sense immaterial whether the
batteries connected with wire A assist or oppose each other, as, in either
will traverse the wires.
The above principles were employed in the Stearns differential duplex
system in the following manner: Referring to Fig. 3, suppose a wire, A, is
led from a battery around a bar of soft iron from left to right, and another
wire of equal resistance and equal number of turns, B, around from right to

be actuated from the distant end, D, it is in a sense immaterial whether the
batteries connected with wire A assist or oppose each other, as, in either
Page 529
case, the bar would be magnetized only through the operation of the distant
key.
A slight elaboration of Fig. 4 will further illustrate the principle of the
differential duplex. In Fig. 5 are two stations, A the home end, and B the
distant station to which a message is to be sent. The relay at each end has
two coils, 1 and 2, No. 1 in each case being known as the "main-line coil"
and 2 as the "artificial-line coil." The latter, in each case, has in its circuit a
resistance, R, to compensate for the resistance of the main line, so that there
shall be no inequalities in the circuits. The artificial line, as well as that to
which the two coils are joined, are connected to earth. There is a battery, C,
and a key, K. When the key is depressed, current flows through the relay
coils at A, but no magnetism is produced, as they oppose each other. The
current, however, flows out through the main-line coil over the line and
through the main-line coil 1 at B, completing its circuit to earth and
magnetizing the bar of the relay, thus causing its armature to be attracted.
On releasing the key the circuit is broken and magnetism instantly ceases.
It will be evident, therefore, that the operator at A may cause the relay at
B to act without affecting his own relay. Similar effects would be produced
from B to A if the battery and key were placed at the B end.
If, therefore, like instruments are placed at each end of the line, as in Fig.
6, we have a differential duplex arrangement by means of which two
operators may actuate relays at the ends distant from them, without causing
the operation of the relays at their home ends. In practice this is done by
means of a special instrument known as a continuity preserving transmitter,
or, usually, as a transmitter. This consists of an electromagnet, T, operated
by a key, K, and separate battery. The armature lever, L, is long, pivoted in
the centre, and is bent over at the end. At a point a little beyond its centre is
a small piece of insulating material to which is screwed a strip of spring
metal, S. Conveniently placed with reference to the end of the lever is a
bent metallic piece, P, having a contact screw in its upper horizontal arm,
and attached to the lower end of this bent piece is a post, or standard, to
which the main battery is electrically connected. The relay coils are
connected by wire to the spring piece, S, and the armature lever is
connected to earth. If the key is depressed, the armature is attracted and its
bent end is moved upward, depressing the spring which makes contact with
the upper screw, which places the battery to the line, and simultaneously
key.

breaks the ground connection between the spring and the upturned end of
the lever, as shown at the left. When the key is released the battery is again
connected to earth. The compensating resistances and condensers necessary
for a duplex arrangement are shown in the diagram.
In Fig. 6 one transmitter is shown as closed, at A, while the other one is
open. From our previous illustrations and explanations it will be readily
seen that, with the transmitter closed at station A, current flows via post P,
through S, and to both relay coils at A, thence over the main line to main-
line coil at B, and down to earth through S and the armature lever with its
grounded wire. The relay at A would be unresponsive, but the core of the
relay at B would be magnetized and its armature respond to signals from A.
In like manner, if the transmitter at B be closed, current would flow through
similar parts and thus cause the relay at A to respond. If both transmitters be
closed simultaneously, both batteries will be placed to the line, which would
practically result in doubling the current in each of the main-line coils, in
consequence of which both relays are energized and their armatures
attracted through the operation of the keys at the distant ends. Hence, two
messages can be sent in opposite directions over the same line
simultaneously.
The reader will undoubtedly see quite clearly from the above system,
which rests upon varying the STRENGTH of the current, that two messages
could not be sent in the same direction over the one line at the same time.
To accomplish this object Edison introduced another and distinct feature—
namely, the using of the same current, but ALSO varying its DIRECTION
of flow; that is to say, alternately reversing the POLARITY of the batteries
as applied to the line and thus producing corresponding changes in the
polarity of another specially constructed type of relay, called a polarized
relay. To afford the reader a clear conception of such a relay we would refer
again to Fig. 1 and its explanation, from which it appears that the polarity of
a soft-iron bar is determined not by the strength of the current flowing
around it but by the direction thereof.
With this idea clearly in mind, the theory of the polarized relay, generally
called "polar" relay, as presented in the diagram (Fig. 7), will be readily
understood.
A is a bar of soft iron, bent as shown, and wound around with insulated
copper wire, the ends of which are connected with a battery, B, thus
the lever, as shown at the left. When the key is released the battery is again
connected to earth. The compensating resistances and condensers necessary
for a duplex arrangement are shown in the diagram.

A is a bar of soft iron, bent as shown, and wound around with insulated

forming an electromagnet. An essential part of this relay consists of a
swinging PERMANENT magnet, C, whose polarity remains fixed, that end
between the terminals of the electromagnet being a north pole. Inasmuch as
unlike poles of magnets are attracted to each other and like poles repelled, it
follows that this north pole will be repelled by the north pole of the
electromagnet, but will swing over and be attracted by its south pole. If the
direction of flow of current be reversed, by reversing the battery, the
electromagnetic polarity also reverses and the end of the permanent magnet
swings over to the other side. This is shown in the two figures of Fig. 7.
This device being a relay, its purpose is to repeat transmitted signals into a
local circuit, as before explained. For this purpose there are provided at D
and E a contact and a back stop, the former of which is opened and closed
by the swinging permanent magnet, thus opening and closing the local
circuit.
Manifestly there must be provided some convenient way for rapidly
transposing the direction of the current flow if such a device as the polar
relay is to be used for the reception of telegraph messages, and this is
accomplished by means of an instrument called a pole-changer, which
consists essentially of a movable contact piece connected permanently to
the earth, or grounded, and arranged to connect one or the other pole of a
battery to the line and simultaneously ground the other pole. This action of
the pole-changer is effected by movements of the armature of an
electromagnet through the manipulation of an ordinary telegraph key by an
operator at the home station, as in the operation of the "transmitter," above
referred to.
By a combination of the neutral relay and the polar relay two operators,
by manipulating two telegraph keys in the ordinary way, can simultaneously
send two messages over one line in the SAME direction with the SAME
current, one operator varying its strength and the other operator varying its
polarity or direction of flow. This principle was covered by Edison's Patent
No. 162,633, and was known as the "diplex" system, although, in the patent
referred to, Edison showed and claimed the adaptation of the principle to
duplex telegraphy. Indeed, as a matter of fact, it was found that by winding
the polar relay differentially and arranging the circuits and collateral
appliances appropriately, the polar duplex system was more highly efficient
than the neutral system, and it is extensively used to the present day.

Thus far we have referred to two systems, one the neutral or differential
duplex, and the other the combination of the neutral and polar relays,
making a diplex system. By one of these two systems a single wire could be
used for sending two messages in opposite directions, and by the other in
the same direction or in opposite directions. Edison followed up his work
on the diplex and combined the two systems into the quadruplex, by means
of which FOUR messages could be sent and received simultaneously over
the one wire, two in each direction, thus employing eight operators—four at
each end—two sending and two receiving. The general principles of
quadruplex telegraphy are based upon the phenomena which we have
briefly outlined in connection with the neutral relay and the polar relay. The
equipment of such a system at each end of the line consists of these two
instruments, together with the special form of transmitter and the pole-
changer and their keys for actuating the neutral and polar relays at the other,
or distant, end. Besides these there are the compensating resistances and
condensers. All of these will be seen in the diagram (Fig. 8). It will be
understood, of course, that the polar relay, as used in the quadruplex
system, is wound differentially, and therefore its operation is somewhat
similar in principle to that of the differentially wound neutral relay, in that it
does not respond to the operation of the key at the home office, but only
operates in response to the movements of the distant key.
Our explanation has merely aimed to show the underlying phenomena
and principles in broad outline without entering into more detail than was
deemed absolutely necessary. It should be stated, however, that between the
outline and the filling in of the details there was an enormous amount of
hard work, study, patient plodding, and endless experiments before Edison
finally perfected his quadruplex system in the year 1874.
If it were attempted to offer here a detailed explanation of the varied and
numerous operations of the quadruplex, this article would assume the
proportions of a treatise. An idea of their complexity may be gathered from
the following, which is quoted from American Telegraphy and
Encyclopedia of the Telegraph, by William Maver, Jr.:
"It may well be doubted whether in the whole range of applied electricity
there occur such beautiful combinations, so quickly made, broken up, and
others reformed, as in the operation of the Edison quadruplex. For example,
it is quite demonstrable that during the making of a simple dash of the
duplex, and the other the combination of the neutral and polar relays,
making a diplex system. By one of these two systems a single wire could be
used for sending two messages in opposite directions, and by the other in
the same direction or in opposite directions. Edison followed up his work

Morse alphabet by the neutral relay at the home station the distant pole-
changer may reverse its battery several times; the home pole-changer may
do likewise, and the home transmitter may increase and decrease the
electromotive force of the home battery repeatedly. Simultaneously, and, of
course, as a consequence of the foregoing actions, the home neutral relay
itself may have had its magnetism reversed several times, and the SIGNAL,
that is, the dash, will have been made, partly by the home battery, partly by
the distant and home batteries combined, partly by current on the main line,
partly by current on the artificial line, partly by the main-line 'static' current,
partly by the condenser static current, and yet, on a well-adjusted circuit the
dash will have been produced on the quadruplex sounder as clearly as any
dash on an ordinary single-wire sounder."
We present a diagrammatic illustration of the Edison quadruplex, battery
key system, in Fig. 8, and refer the reader to the above or other text-books if
he desires to make a close study of its intricate operations. Before finally
dismissing the quadruplex, and for the benefit of the inquiring reader who
may vainly puzzle over the intricacies of the circuits shown in Fig. 8, a hint
as to an essential difference between the neutral relay, as used in the duplex
and as used in the quadruplex, may be given. With the duplex, as we have
seen, the current on the main line is changed in strength only when both
keys at OPPOSITE stations are closed together, so that a current due to both
batteries flows over the main line. When a single message is sent from one
station to the other, or when both stations are sending messages that do not
conflict, only one battery or the other is connected to the main line; but with
the quadruplex, suppose one of the operators, in New York for instance, is
sending reversals of current to Chicago; we can readily see how these
changes in polarity will operate the polar relay at the distant station, but
why will they not also operate the neutral relay at the distant station as
well? This difficulty was solved by dividing the battery at each station into
two unequal parts, the smaller battery being always in circuit with the pole-
changer ready to have its polarity reversed on the main line to operate the
distant polar relay, but the spring retracting the armature of the neutral relay
is made so stiff as to resist these weak currents. If, however, the transmitter
is operated at the same end, the entire battery is connected to the main line,
and the strength of this current is sufficient to operate the neutral relay.
Whether the part or all the battery is alternately connected to or
disconnected from the main line by the transmitter, the current so varied in
changer may reverse its battery several times; the home pole-changer may
do likewise, and the home transmitter may increase and decrease the
electromotive force of the home battery repeatedly. Simultaneously, and, of
course, as a consequence of the foregoing actions, the home neutral relay
itself may have had its magnetism reversed several times, and the SIGNAL,
that is, the dash, will have been made, partly by the home battery, partly by
the distant and home batteries combined, partly by current on the main line,
partly by current on the artificial line, partly by the main-line 'static' current,
partly by the condenser static current, and yet, on a well-adjusted circuit the
dash will have been produced on the quadruplex sounder as clearly as any
dash on an ordinary single-wire sounder."

Whether the part or all the battery is alternately connected to or

Page 534
strength is subject to reversal of polarity by the pole-changer; but the
variations in strength have no effect upon the distant polar relay, because
that relay being responsive to changes in polarity of a weak current is
obviously responsive to corresponding changes in polarity of a powerful
current. With this distinction before him, the reader will have no difficulty
in following the circuits of Fig. 8, bearing always in mind that by reason of
the differential winding of the polar and neutral relays, neither of the relays
at one station will respond to the home battery, and can only respond to the
distant battery—the polar relay responding when the polarity of the current
is reversed, whether the current be strong or weak, and the neutral relay
responding when the line-current is increased, regardless of its polarity. It
should be added that besides the system illustrated in Fig. 8, which is
known as the differential principle, the quadruplex was also arranged to
operate on the Wheatstone bridge principle; but it is not deemed necessary
to enter into its details. The underlying phenomena were similar, the
difference consisting largely in the arrangement of the circuits and
apparatus. [24]

Edison made another notable contribution to multiplex telegraphy some
years later in the Phonoplex. The name suggests the use of the telephone,
and such indeed is the case. The necessity for this invention arose out of the
problem of increasing the capacity of telegraph lines employed in "through"
and "way" service, such as upon railroads. In a railroad system there are
usually two terminal stations and a number of way stations. There is
naturally much intercommunication, which would be greatly curtailed by a
system having the capacity of only a single message at a time. The duplexes
above described could not be used on a railroad telegraph system, because
of the necessity of electrically balancing the line, which, while entirely
feasible on a through line, would not be practicable between a number of
intercommunicating points. Edison's phonoplex normally doubled the
capacity of telegraph lines, whether employed on way business or through
traffic, but in actual practice made it possible to obtain more than double
service. It has been in practical use for many years on some of the leading
railroads of the United States.

The system is a combination of telegraphic apparatus and telephone
receiver, although in this case the latter instrument is not used in the
generally understood manner. It is well known that the diaphragm of a
telephone vibrates with the fluctuations of the current energizing the magnet
beneath it. If the make and break of the magnetizing current be rapid, the
vibrations being within the limits of the human ear, the diaphragm will
produce an audible sound; but if the make and break be as slow as with
ordinary Morse transmission, the diaphragm will be merely flexed and
return to its original form without producing a sound. If, therefore, there be
placed in the same circuit a regular telegraph relay and a special telephone,
an operator may, by manipulating a key, operate the relay (and its sounder)
without producing a sound in the telephone, as the makes and breaks of the
key are far below the limit of audibility. But if through the same circuit, by
means of another key suitably connected there is sent the rapid changes in
current from an induction-coil, it will cause a series of loud clicks in the
telephone, corresponding to the signals transmitted; but this current is too
weak to affect the telegraph relay. It will be seen, therefore, that this method
of duplexing is practiced, not by varying the strength or polarity, but by
sending TWO KINDS OF CURRENT over the wire. Thus, two sets of
Morse signals can be transmitted by two operators over one line at the same
time without interfering with each other, and not only between terminal
offices, but also between a terminal office and any intermediate office, or
between two intermediate offices alone.

AUTOMATIC TELEGRAPHY
FROM the year 1848, when a Scotchman, Alexander Bain, first devised a
scheme for rapid telegraphy by automatic methods, down to the beginning
of the seventies, many other inventors had also applied themselves to the
solution of this difficult problem, with only indifferent success. "Cheap
telegraphy" being the slogan of the time, Edison became arduously
interested in the subject, and at the end of three years of hard work
produced an entirely successful system, a public test of which was made on
December 11, 1873 when about twelve thousand (12,000) words were
transmitted over a single wire from Washington to New York. in twenty-two
and one-half minutes. Edison's system was commercially exploited for
several years by the Automatic Telegraph Company, as related in the
preceding narrative.
As a premise to an explanation of the principles involved it should be
noted that the transmission of telegraph messages by hand at a rate of fifty
words per minute is considered a good average speed; hence, the
availability of a telegraph line, as thus operated, is limited to this capacity
except as it may be multiplied by two with the use of the duplex, or by four,
with the quadruplex. Increased rapidity of transmission may, however, be
accomplished by automatic methods, by means of which, through the
employment of suitable devices, messages may be stamped in or upon a

AUTOMATIC TELEGRAPHY
FROM the year 1848, when a Scotchman, Alexander Bain, first devised a
scheme for rapid telegraphy by automatic methods, down to the beginning
of the seventies, many other inventors had also applied themselves to the
solution of this difficult problem, with only indifferent success. "Cheap
telegraphy" being the slogan of the time, Edison became arduously
interested in the subject, and at the end of three years of hard work
produced an entirely successful system, a public test of which was made on
December 11, 1873 when about twelve thousand (12,000) words were
transmitted over a single wire from Washington to New York. in twenty-two
and one-half minutes. Edison's system was commercially exploited for
several years by the Automatic Telegraph Company, as related in the
preceding narrative.
As a premise to an explanation of the principles involved it should be
noted that the transmission of telegraph messages by hand at a rate of fifty
words per minute is considered a good average speed; hence, the
availability of a telegraph line, as thus operated, is limited to this capacity
except as it may be multiplied by two with the use of the duplex, or by four,
with the quadruplex. Increased rapidity of transmission may, however, be
accomplished by automatic methods, by means of which, through the
employment of suitable devices, messages may be stamped in or upon a
paper tape, transmitted through automatically acting instruments, and be
received at distant points in visible characters, upon a similar tape, at a rate
twenty or more times greater—a speed far beyond the possibilities of the
human hand to transmit or the ear to receive.
In Edison's system of automatic telegraphy a paper tape was perforated
with a series of round holes, so arranged and spaced as to represent Morse
characters, forming the words of the message to be transmitted. This was
done in a special machine of Edison's invention, called a perforator,
consisting of a series of punches operated by a bank of keys—typewriter

fashion. The paper tape passed over a cylinder, and was kept in regular
motion so as to receive the perforations in proper sequence.
The perforated tape was then placed in the transmitting instrument, the
essential parts of which were a metallic drum and a projecting arm carrying
two small wheels, which, by means of a spring, were maintained in constant
pressure on the drum. The wheels and drum were electrically connected in
the line over which the message was to be sent. current being supplied by
batteries in the ordinary manner.
When the transmitting instrument was in operation, the perforated tape
was passed over the drum in continuous, progressive motion. Thus, the
paper passed between the drum and the two small wheels, and, as dry paper
is a non-conductor, current was prevented from passing until a perforation
was reached. As the paper passed along, the wheels dropped into the
perforations, making momentary contacts with the drum beneath and
causing momentary impulses of current to be transmitted over the line in
the same way that they would be produced by the manipulation of the
telegraph key, but with much greater rapidity. The perforations being so
arranged as to regulate the length of the contact, the result would be the
transmission of long and short impulses corresponding with the dots and
dashes of the Morse alphabet.
The receiving instrument at the other end of the line was constructed
upon much the same general lines as the transmitter, consisting of a metallic
drum and reels for the paper tape. Instead of the two small contact wheels,
however, a projecting arm carried an iron pin or stylus, so arranged that its
point would normally impinge upon the periphery of the drum. The iron pin
and the drum were respectively connected so as to be in circuit with the
transmission line and batteries. As the principle involved in the receiving
operation was electrochemical decomposition, the paper tape upon which
the incoming message was to be received was moistened with a chemical
solution readily decomposable by the electric current. This paper, while still
in a damp condition, was passed between the drum and stylus in
continuous, progressive motion. When an electrical impulse came over the
line from the transmitting end, current passed through the moistened paper
from the iron pin, causing chemical decomposition, by reason of which the
iron would be attacked and would mark a line on the paper. Such a line
would be long or short, according to the duration of the electric impulse.

The perforated tape was then placed in the transmitting instrument, the
essential parts of which were a metallic drum and a projecting arm carrying

causing momentary impulses of current to be transmitted over the line in

telegraph key, but with much greater rapidity. The perforations being so

transmission of long and short impulses corresponding with the dots and

The receiving instrument at the other end of the line was constructed
upon much the same general lines as the transmitter, consisting of a metallic
drum and reels for the paper tape. Instead of the two small contact wheels,
however, a projecting arm carried an iron pin or stylus, so arranged that its
point would normally impinge upon the periphery of the drum. The iron pin

from the iron pin, causing chemical decomposition, by reason of which the
iron would be attacked and would mark a line on the paper. Such a line
would be long or short, according to the duration of the electric impulse.
Page 538
Inasmuch as a succession of such impulses coming over the line owed their
origin to the perforations in the transmitting tape, it followed that the
resulting marks upon the receiving tape would correspond thereto in their
respective lengths. Hence, the transmitted message was received on the tape
in visible dots and dashes representing characters of the Morse alphabet.
The system will, perhaps, be better understood by reference to the
following diagrammatic sketch of its general principles:
Some idea of the rapidity of automatic telegraphy may be obtained when
we consider the fact that with the use of Edison's system in the early
seventies it was common practice to transmit and receive from three to four
thousand words a minute over a single line between New York and
Philadelphia. This system was exploited through the use of a moderately
paid clerical force.
In practice, there was employed such a number of perforating machines
as the exigencies of business demanded. Each machine was operated by a
clerk, who translated the message into telegraphic characters and prepared
the transmitting tape by punching the necessary perforations therein. An
expert clerk could perforate such a tape at the rate of fifty to sixty words per
minute. At the receiving end the tape was taken by other clerks who
translated the Morse characters into ordinary words, which were written on
message blanks for delivery to persons for whom the messages were
intended.
This latter operation—"copying." as it was called—was not consistent
with truly economical business practice. Edison therefore undertook the
task of devising an improved system whereby the message when received
would not require translation and rewriting, but would automatically appear
on the tape in plain letters and words, ready for instant delivery.
The result was his automatic Roman letter system, the basis for which
included the above-named general principles of perforated transmission
tape and electrochemical decomposition. Instead of punching Morse
characters in the transmission tape however, it was perforated with a series
of small round holes forming Roman letters. The verticals of these letters
were originally five holes high. The transmitting instrument had five small
wheels or rollers, instead of two, for making contacts through the
perforations and causing short electric impulses to pass over the lines. At
first five lines were used to carry these impulses to the receiving instrument,
origin to the perforations in the transmitting tape, it followed that the
resulting marks upon the receiving tape would correspond thereto in their
respective lengths. Hence, the transmitted message was received on the tape
in visible dots and dashes representing characters of the Morse alphabet.

first five lines were used to carry these impulses to the receiving instrument,
Page 539
where there were five iron pins impinging on the drum. By means of these
pins the chemically prepared tape was marked with dots corresponding to
the impulses as received, leaving upon it a legible record of the letters and
words transmitted.
For purposes of economy in investment and maintenance, Edison devised
subsequently a plan by which the number of conducting lines was reduced
to two, instead of five. The verticals of the letters were perforated only four
holes high, and the four rollers were arranged in pairs, one pair being
slightly in advance of the other. There were, of course, only four pins at the
receiving instrument. Two were of iron and two of tellurium, it being the
gist of Edison's plan to effect the marking of the chemical paper by one
metal with a positive current, and by the other metal with a negative
current. In the following diagram, which shows the theory of this
arrangement, it will be seen that both the transmitting rollers and the
receiving pins are arranged in pairs, one pair in each case being slightly in
advance of the other. Of these receiving pins, one pair—1 and 3—are of
iron, and the other pair—2 and 4—of tellurium. Pins 1-2 and 3-4 are
electrically connected together in other pairs, and then each of these pairs is
connected with one of the main lines that run respectively to the middle of
two groups of batteries at the transmitting end. The terminals of these
groups of batteries are connected respectively to the four rollers which
impinge upon the transmitting drum, the negatives being connected to 5 and
7, and the positives to 6 and 8, as denoted by the letters N and P. The
transmitting and receiving drums are respectively connected to earth.
In operation the perforated tape is placed on the transmission drum, and
the chemically prepared tape on the receiving drum. As the perforated tape
passes over the transmission drum the advanced rollers 6 or 8 first close the
circuit through the perforations, and a positive current passes from the
batteries through the drum and down to the ground; thence through the
earth at the receiving end up to the other drum and back to the batteries via
the tellurium pins 2 or 4 and the line wire. With this positive current the
tellurium pins make marks upon the paper tape, but the iron pins make no
mark. In the merest fraction of a second, as the perforated paper continues
to pass over the transmission drum, the rollers 5 or 7 close the circuit
through other perforations and t e current passes in the opposite direction,
over the line wire, through pins 1 or 3, and returns through the earth. In this
case the iron pins mark the paper tape, but the tellurium pins make no mark.

over the line wire, through pins 1 or 3, and returns through the earth. In this
case the iron pins mark the paper tape, but the tellurium pins make no mark.
Page 540
It will be obvious, therefore, that as the rollers are set so as to allow of
currents of opposite polarity to be alternately and rapidly sent by means of
the perforations, the marks upon the tape at the receiving station will
occupy their proper relative positions, and the aggregate result will be
letters corresponding to those perforated in the transmission tape.
Edison subsequently made still further improvements in this direction, by
which he reduced the number of conducting wires to one, but the principles
involved were analogous to the one just described.
This Roman letter system was in use for several years on lines between
New York, Philadelphia, and Washington, and was so efficient that a speed
of three thousand words a minute was attained on the line between the two
first-named cities.
Inasmuch as there were several proposed systems of rapid automatic
telegraphy in existence at the time Edison entered the field, but none of
them in practical commercial use, it becomes a matter of interest to inquire
wherein they were deficient, and what constituted the elements of Edison's
success.
The chief difficulties in the transmission of Morse characters had been
two in number, the most serious of which was that on the receiving tape the
characters would be prolonged and run into one another, forming a draggled
line and thus rendering the message unintelligible. This arose from the fact
that, on account of the rapid succession of the electric impulses, there was
not sufficient time between them for the electric action to cease entirely.
Consequently the line could not clear itself, and became surcharged, as it
were; the effect being an attenuated prolongation of each impulse as
manifested in a weaker continuation of the mark on the tape, thus making
the whole message indistinct. These secondary marks were called "tailings."
For many years electricians had tried in vain to overcome this difficulty.
Edison devoted a great deal of thought and energy to the question, in the
course of which he experimented through one hundred and twenty
consecutive nights, in the year 1873, on the line between New York and
Washington. His solution of the problem was simple but effectual. It
involved the principle of inductive compensation. In a shunt circuit with the
receiving instrument he introduced electromagnets. The pulsations of
current passed through the helices of these magnets, producing an
augmented marking effect upon the receiving tape, but upon the breaking of
currents of opposite polarity to be alternately and rapidly sent by means of
the perforations, the marks upon the tape at the receiving station will
occupy their proper relative positions, and the aggregate result will be
letters corresponding to those perforated in the transmission tape.

current passed through the helices of these magnets, producing an
augmented marking effect upon the receiving tape, but upon the breaking of
Page 541
the current, the magnet, in discharging itself of the induced magnetism,
would set up momentarily a counter-current of opposite polarity. This
neutralized the "tailing" effect by clearing the line between pulsations, thus
allowing the telegraphic characters to be clearly and distinctly outlined
upon the tape. Further elaboration of this method was made later by the
addition of rheostats, condensers, and local opposition batteries on long
lines.
The other difficulty above referred to was one that had also occupied
considerable thought and attention of many workers in the field, and related
to the perforating of the dash in the transmission tape. It involved
mechanical complications that seemed to be insurmountable, and up to the
time Edison invented his perforating machine no really good method was
available. He abandoned the attempt to cut dashes as such, in the paper
tape, but instead punched three round holes so arranged as to form a
triangle. A concrete example is presented in the illustration below, which
shows a piece of tape with perforations representing the word "same."
The philosophy of this will be at once perceived when it is remembered
that the two little wheels running upon the drum of the transmitting
instrument were situated side by side, corresponding in distance to the two
rows of holes. When a triangle of three holes, intended to form the dash,
reached the wheels, one of them dropped into a lower hole. Before it could
get out, the other wheel dropped into the hole at the apex of the triangle,
thus continuing the connection, which was still further prolonged by the
first wheel dropping into the third hole. Thus, an extended contact was
made, which, by transmitting a long impulse, resulted in the marking of a
dash upon the receiving tape.
This method was in successful commercial use for some time in the early
seventies, giving a speed of from three to four thousand words a minute
over a single line, but later on was superseded by Edison's Roman letter
system, above referred to.
The subject of automatic telegraphy received a vast amount of attention
from inventors at the time it was in vogue. None was more earnest or
indefatigable than Edison, who, during the progress of his investigations,
took out thirty-eight patents on various inventions relating thereto, some of
them covering chemical solutions for the receiving paper. This of itself was
a subject of much importance and a vast amount of research and labor was

expended upon it. In the laboratory note-books there are recorded thousands
of experiments showing that Edison's investigations not only included an
enormous number of chemical salts and compounds, but also an exhaustive
variety of plants, flowers, roots, herbs, and barks.
It seems inexplicable at first view that a system of telegraphy sufficiently
rapid and economical to be practically available for important business
correspondence should have fallen into disuse. This, however, is made clear
—so far as concerns Edison's invention at any rate—in Chapter VIII of the

IV. WIRELESS TELEGRAPHY
ALTHOUGH Mr. Edison has taken no active part in the development of
the more modern wireless telegraphy, and his name has not occurred in
connection therewith, the underlying phenomena had been noted by him
many years in advance of the art, as will presently be explained. The
authors believe that this explanation will reveal a status of Edison in
relation to the subject that has thus far been unknown to the public.
While the term "wireless telegraphy," as now applied to the modern
method of electrical communication between distant points without
intervening conductors, is self-explanatory, it was also applicable, strictly
speaking, to the previous art of telegraphing to and from moving trains, and
between points not greatly remote from each other, and not connected
together with wires.
The latter system (described in Chapter XXIII and in a succeeding article
of this Appendix) was based upon the phenomena of electromagnetic or
electrostatic induction between conductors separated by more or less space,
whereby electric impulses of relatively low potential and low frequency set
up in. one conductor were transmitted inductively across the air to another
conductor, and there received through the medium of appropriate
instruments connected therewith.
As distinguished from this system, however, modern wireless telegraphy
—so called—has its basis in the utilization of electric or ether waves in free
space, such waves being set up by electric oscillations, or surgings, of
comparatively high potential and high frequency, produced by the operation
of suitable electrical apparatus. Broadly speaking, these oscillations arise
from disruptive discharges of an induction coil, or other form of oscillator,
across an air-gap, and their character is controlled by the manipulation of a
special type of circuit-breaking key, by means of which long and short
discharges are produced. The electric or etheric waves thereby set up are
detected and received by another special form of apparatus more or less
distant, without any intervening wires or conductors.

In November, 1875, Edison, while experimenting in his Newark
laboratory, discovered a new manifestation of electricity through mysterious
sparks which could be produced under conditions unknown up to that time.
Recognizing at once the absolutely unique character of the phenomena, he
continued his investigations enthusiastically over two mouths, finally
arriving at a correct conclusion as to the oscillatory nature of the hitherto
unknown manifestations. Strange to say, however, the true import and
practical applicability of these phenomena did not occur to his mind.
Indeed, it was not until more than TWELVE YEARS AFTERWARD, in
1887, upon the publication of the notable work of Prof. H. Hertz proving
the existence of electric waves in free space, that Edison realized the fact
that the fundamental principle of aerial telegraphy had been within his grasp
in the winter of 1875; for although the work of Hertz was more profound
and mathematical than that of Edison, the principle involved and the
phenomena observed were practically identical—in fact, it may be
remarked that some of the methods and experimental apparatus were quite
similar, especially the "dark box" with micrometer adjustment, used by both
in observing the spark. [25]
[Footnote 25: During the period in which Edison exhibited
his lighting system at the Paris Exposition in 1881, his
representative, Mr. Charles Batchelor, repeated Edison's
remarkable experiments of the winter of 1875 for the benefit
of a great number of European savants, using with other
apparatus the original "dark box" with micrometer
adjustment.]
There is not the slightest intention on the part of the authors to detract in
the least degree from the brilliant work of Hertz, but, on the contrary, to
ascribe to him the honor that is his due in having given mathematical
direction and certainty to so important a discovery. The adaptation of the
principles thus elucidated and the subsequent development of the present
wonderful art by Marconi, Branly, Lodge, Slaby, and others are now too
well known to call for further remark at this place.
Strange to say, that although Edison's early experiments in "etheric force"
called forth extensive comment and discussion in the public prints of the
period, they seemed to have been generally overlooked when the work of
Hertz was published. At a meeting of the Institution of Electrical Engineers,
held in London on May 16, 1889, at which there was a discussion on the
celebrated paper of Prof. (Sir) Oliver Lodge on "Lightning Conductors,"
laboratory, discovered a new manifestation of electricity through mysterious
sparks which could be produced under conditions unknown up to that time.

continued his investigations enthusiastically over two mouths, finally

ascribe to him the honor that is his due in having given mathematical
direction and certainty to so important a discovery. The adaptation of the
principles thus elucidated and the subsequent development of the present
wonderful art by Marconi, Branly, Lodge, Slaby, and others are now too
well known to call for further remark at this place.
Strange to say, that although Edison's early experiments in "etheric force"
called forth extensive comment and discussion in the public prints of the
period, they seemed to have been generally overlooked when the work of
Hertz was published. At a meeting of the Institution of Electrical Engineers,
held in London on May 16, 1889, at which there was a discussion on the
celebrated paper of Prof. (Sir) Oliver Lodge on "Lightning Conductors,"
Page 545
however; the chairman, Sir William Thomson (Lord Kelvin), made the
following remarks:
"We all know how Faraday made himself a cage six feet in diameter,
hung it up in mid-air in the theatre of the Royal Institution, went into it,
and, as he said, lived in it and made experiments. It was a cage with tin-foil
hanging all round it; it was not a complete metallic enclosing shell. Faraday
had a powerful machine working in the neighborhood, giving all varieties
of gradual working-up and discharges by 'impulsive rush'; and whether it
was a sudden discharge of ordinary insulated conductors, or of Leyden jars
in the neighborhood outside the cage, or electrification and discharge of the
cage itself, he saw no effects on his most delicate gold-leaf electroscopes in
the interior. His attention was not directed to look for Hertz sparks, or
probably he might have found them in the interior. Edison seems to have
noticed something of the kind in what he called the etheric force. His name
'etheric' may, thirteen years ago, have seemed to many people absurd. But
now we are all beginning to call these inductive phenomena 'etheric.'"
With these preliminary observations, let us now glance briefly at Edison's
laboratory experiments, of which mention has been made.
Oh the first manifestation of the unusual phenomena in November, 1875,
Edison's keenness of perception led him at once to believe that he had
discovered a new force. Indeed, the earliest entry of this discovery in the
laboratory note-book bore that caption. After a few days of further
experiment and observation, however, he changed it to "Etheric Force," and
the further records thereof (all in Mr. Batchelor's handwriting) were under
that heading.
The publication of Edison's discovery created considerable attention at
the time, calling forth a storm of general ridicule and incredulity. But a few
scientific men of the period, whose experimental methods were careful and
exact, corroborated his deductions after obtaining similar phenomena by
repeating his experiments with intelligent precision. Among these was the
late Dr. George M. Beard, a noted physicist, who entered enthusiastically
into the investigation, and, in addition to a great deal of independent
experiment, spent much time with Edison at his laboratory. Doctor Beard
wrote a treatise of some length on the subject, in which he concurred with
Edison's deduction that the phenomena were the manifestation of
oscillations, or rapidly reversing waves of electricity, which did not respond

to the usual tests. Edison had observed the tendency of this force to diffuse
itself in various directions through the air and through matter, hence the
name "Etheric" that he had provisionally applied to it.
Edison's laboratory notes on this striking investigation are fascinating
and voluminous, but cannot be reproduced in full for lack of space. In view
of the later practical application of the principles involved, however, the
reader will probably be interested in perusing a few extracts therefrom as
illustrated by facsimiles of the original sketches from the laboratory note-
book.
As the full significance of the experiments shown by these extracts may
not be apparent to a lay reader, it may be stated by way of premise that,
ordinarily, a current only follows a closed circuit. An electric bell or electric
light is a familiar instance of this rule. There is in each case an open (wire)
circuit which is closed by pressing the button or turning the switch, thus
making a complete and uninterrupted path in which the current may travel
and do its work. Until the time of Edison's investigations of 1875, now
under consideration, electricity had never been known to manifest itself
except through a closed circuit. But, as the reader will see from the
following excerpts, Edison discovered a hitherto unknown phenomenon—
namely, that under certain conditions the rule would be reversed and
electricity would pass through space and through matter entirely
unconnected with its point of origin. In other words, he had found the
forerunner of wireless telegraphy. Had he then realized the full import of his
discovery, all he needed was to increase the strength of the waves and to
provide a very sensitive detector, like the coherer, in order to have
anticipated the principal developments that came many years afterward.
With these explanatory observations, we will now turn to the excerpts
referred to, which are as follows:
"November 22, 1875. New Force.—In experimenting with a vibrator
magnet consisting of a bar of Stubb's steel fastened at one end and made to
vibrate by means of a magnet, we noticed a spark coming from the cores of
the magnet. This we have noticed often in relays, in stock-printers, when
there were a little iron filings between the armature and core, and more
often in our new electric pen, and we have always come to the conclusion
that it was caused by strong induction. But when we noticed it on this
vibrator it seemed so strong that it struck us forcibly there might be
itself in various directions through the air and through matter, hence the
name "Etheric" that he had provisionally applied to it.

something more than induction. We now found that if we touched any
metallic part of the vibrator or magnet we got the spark. The larger the body
of iron touched to the vibrator the larger the spark. We now connected a
wire to X, the end of the vibrating rod, and we found we could get a spark
from it by touching a piece of iron to it, and one of the most curious
phenomena is that if you turn the wire around on itself and let the point of
the wire touch any other portion of itself you get a spark. By connecting X
to the gas-pipe we drew sparks from the gas-pipes in any part of the room
by drawing an iron wire over the brass jet of the cock. This is simply
wonderful, and a good proof that the cause of the spark is a TRUE
UNKNOWN FORCE."
"November 23, 1815. New Force.—The following very curious result
was obtained with it. The vibrator shown in Fig. 1 and battery were placed
on insulated stands; and a wire connected to X (tried both copper and iron)
carried over to the stove about twenty feet distant. When the end of the wire
was rubbed on the stove it gave out splendid sparks. When permanently
connected to the stove, sparks could be drawn from the stove by a piece of
wire held in the hand. The point X of vibrator was now connected to the
gas-pipe and still the sparks could be drawn from the stove."

"Put a coil of wire over the end of rod X and passed the ends of spool
through galvanometer without affecting it in any way. Tried a 6-ohm spool

the point X." [Here follows a list of metals and the character of spark
obtained with each.]

"By increasing the battery from eight to twelve cells we get a spark when
the vibrating magnet is shunted with 3 ohms. Cannot taste the least shock at
B, yet between carbon points the spark is very vivid. As will be seen, X has
no connection with anything. With a glass rod four feet long, well rubbed
with a piece of silk over a hot stove, with a piece of battery carbon secured
to one end, we received vivid sparks into the carbon when the other end was
held in the hand with the handkerchief, yet the galvanometer, chemical

would diverge at two feet from a half-inch spark plate-glass machine were

"A piece of coal held to the wire showed faint sparks.

within a dark box provided with an eyepiece. The points were iron, and we
found the sparks were very irregular. After testing some time two lead-
pencils found more regular and very much more vivid. We then substituted
the graphite points instead of iron." [26]

delicate adjustment of the carbon points, and was thereafter
largely used in this series of investigations for better
study of the spark. When Mr. Edison's experiments were
repeated by Mr. Batchelor, who represented him at the Paris
Exposition of 1881, the dark box was employed for a similar
purpose.]

After recording a considerable number of other experiments, the
laboratory notes go on to state:
"November 30, 1875. Etheric Force.—We found the addition of battery
to the Stubb's wire vibrator greatly increased the volume of spark. Several
persons could obtain sparks from the gas-pipes at once, each spark being
equal in volume and brilliancy to the spark drawn by a single person....
Edison now grasped the (gas) pipe, and with the other hand holding a piece
of metal, he touched several other metallic substances, obtained sparks,
showing that the force passed through his body."

"December 3, 1875. Etheric Force.—Charley Edison hung to the gas-pipe
with feet above the floor, and with a knife got a spark from the pipe he was
hanging on. We now took the wire from the vibrator in one hand and stood
on a block of paraffin eighteen inches square and six inches thick; holding a
knife in the other hand, we drew sparks from the stove-pipe. We now tried
the crucial test of passing the etheric current through the sciatic nerve of a
frog just killed. Previous to trying, we tested its sensibility by the current
from a single Bunsen cell. We put in resistance up to 500,000 ohms, and the
twitching was still perceptible. We tried the induced current from our
induction coil having one cell on primary,, the spark jumping about one-
fiftieth of an inch, the terminal of the secondary connected to the frog and it
straightened out with violence. We arranged frog's legs to pass etheric force
through. We placed legs on an inverted beaker, and held the two ends of the

when the frog was in circuit. Doctor Beard was present when this was
tried."

"December 5, 1875. Etheric Force.—Three persons grasping hands and
standing upon blocks of paraffin twelve inches square and six thick drew
sparks from the adjoining stove when another person touched the sounder
with any piece of metal.... A galvanoscopic frog giving contractions with
one cell through two water rheostats was then placed in circuit. When the
wires from the vibrator and the gas-pipe were connected, slight contractions
were noted, sometimes very plain and marked, showing the apparent
presence of electricity, which from the high insulation seemed improbable.
Doctor Beard, who was present, inferred from the way the leg contracted
that it moved on both opening and closing the circuit. To test this we
disconnected the wire between the frog and battery, and placed, instead of a
vibrating sounder, a simple Morse key and a sounder taking the 'etheric'
from armature. The spark was now tested in dark box and found to be very
strong. It was then connected to the nerves of the frog, BUT NO
MOVEMENT OF ANY KIND COULD BE DETECTED UPON
WORKING THE KEY, although the brilliancy and power of the spark were
undiminished. The thought then occurred to Edison that the movement of
the frog was due to mechanical vibrations from the vibrator (which gives
probably two hundred and fifty vibrations per second), passing through the
wires and irritating the sensitive nerves of the frog. Upon disconnecting the
battery wires and holding a tuning-fork giving three hundred and twenty-six
vibrations per second to the base of the sounder, the vibrations over the wire
made the frog contract nearly every time.... The contraction of the frog's
legs may with considerable safety be said to be caused by these mechanical
vibrations being transmitted through the conducting wires."
Edison thought that the longitudinal vibrations caused by the sounder
produced a more marked effect, and proceeded to try out his theory. The
very next entry in the laboratory note-book bears the same date as the above
(December 5, 1875), and is entitled "Longitudinal Vibrations," and reads as
follows:

"We took a long iron wire one-sixteenth of an inch in diameter and
rubbed it lengthways with a piece of leather with resin on for about three
feet, backward and forward. About ten feet away we applied the wire to the
back of the neck and it gives a horrible sensation, showing the vibrations
conducted through the wire."

The following experiment illustrates notably the movement of the electric
waves through free space:
"December 26, 1875. Etheric Force.—An experiment tried to-night gives
a curious result. A is a vibrator, B, C, D, E are sheets of tin-foil hung on
insulating stands. The sheets are about twelve by eight inches. B and C are
twenty-six inches apart, C and D forty-eight inches and D and E twenty-six
inches. B is connected to the vibrator and E to point in dark box, the other
point to ground. We received sparks at intervals, although insulated by such
space."
With the above our extracts must close, although we have given but a few
of the interesting experiments tried at the time. It will be noticed, however,
that these records show much progression in a little over a month. Just after
the item last above extracted, the Edison shop became greatly rushed on
telegraphic inventions, and not many months afterward came the removal to
Menlo Park; hence the etheric-force investigations were side-tracked for
other matters deemed to be more important at that time.
Doctor Beard in his previously mentioned treatise refers, on page 27, to
the views of others who have repeated Edison's experiments and observed
the phenomena, and in a foot-note says:

of the subject, the hypothesis of rapidly reversed electricity as suggested in
my letter to the Tribune of December 8th, and further claims priority of
discovery, because he observed the spark of this when experimenting with a
Ruhmkorff coil four years ago. To this claim, if it be seriously entertained,
the obvious reply is that thousands of persons, probably, had seen this spark
before it was DISCOVERED by Mr. Edison; it had been seen by Professor
Nipher, who supposed, and still supposes, it is the spark of the extra current;

Edison took out only one patent on long-distance telegraphy without
wires. While the principle involved therein (induction) was not precisely
analogous to the above, or to the present system of wireless telegraphy, it
was a step forward in the progress of the art. The application was filed May
23, 1885, at the time he was working on induction telegraphy (two years
before the publication of the work of Hertz), but the patent (No. 465,971)
was not issued until December 29, 1891. In 1903 it was purchased from him
by the Marconi Wireless Telegraph Company. Edison has always had a
great admiration for Marconi and his work, and a warm friendship exists
between the two men. During the formative period of the Marconi
Company attempts were made to influence Edison to sell this patent to an
opposing concern, but his regard for Marconi and belief in the fundamental
nature of his work were so strong that he refused flatly, because in the
hands of an enemy the patent might be used inimically to Marconi's
interests.
Edison's ideas, as expressed in the specifications of this patent, show very
clearly the close analogy of his system to that now in vogue. As they were
filed in the Patent Office several years before the possibility of wireless
telegraphy was suspected, it will undoubtedly be of interest to give the
following extract therefrom:
"I have discovered that if sufficient elevation be obtained to overcome
the curvature of the earth's surface and to reduce to the minimum the earth's
absorption, electric telegraphing or signalling between distant points can be
carried on by induction without the use of wires connecting such distant
points. This discovery is especially applicable to telegraphing across bodies
of water, thus avoiding the use of submarine cables, or for communicating

the curvature of the earth's surface and to reduce to the minimum the earth's
absorption, electric telegraphing or signalling between distant points can be
carried on by induction without the use of wires connecting such distant
points. This discovery is especially applicable to telegraphing across bodies
of water, thus avoiding the use of submarine cables, or for communicating
Page 552
between vessels at sea, or between vessels at sea and points on land, but it is
also applicable to electric communication between distant points on land, it
being necessary, however, on land (with the exception of communication
over open prairie) to increase the elevation in order to reduce to the
minimum the induction-absorbing effect of houses, trees, and elevations in
the land itself. At sea from an elevation of one hundred feet I can
communicate electrically a great distance, and since this elevation or one
sufficiently high can be had by utilizing the masts of ships, signals can be
sent and received between ships separated a considerable distance, and by
repeating the signals from ship to ship communication can be established
between points at any distance apart or across the largest seas and even
oceans. The collision of ships in fogs can be prevented by this character of
signalling, by the use of which, also, the safety of a ship in approaching a
dangerous coast in foggy weather can be assured. In communicating
between points on land, poles of great height can be used, or captive
balloons. At these elevated points, whether upon the masts of ships, upon
poles or balloons, condensing surfaces of metal or other conductor of
electricity are located. Each condensing surface is connected with earth by
an electrical conducting wire. On land this earth connection would be one
of usual character in telegraphy. At sea the wire would run to one or more
metal plates on the bottom of the vessel, where the earth connection would
be made with the water. The high-resistance secondary circuit of an
induction coil is located in circuit between the condensing surface and the
ground. The primary circuit of the induction coil includes a battery and a
device for transmitting signals, which may be a revolving circuit-breaker
operated continually by a motor of any suitable kind, either electrical or
mechanical, and a key normally short-circuiting the circuit-breaker or
secondary coil. For receiving signals I locate in said circuit between the
condensing surface and the ground a diaphragm sounder, which is
preferably one of my electromotograph telephone receivers. The key
normally short-circuiting the revolving circuit-breaker, no impulses are
produced in the induction coil until the key is depressed, when a large
number of impulses are produced in the primary, and by means of the
secondary corresponding impulses or variations in tension are produced at
the elevated condensing surface, producing thereat electrostatic impulses.
These electrostatic impulses are transmitted inductively to the elevated
condensing surface at the distant point, and are made audible by the
also applicable to electric communication between distant points on land, it

V. THE ELECTROMOTOGRAPH
IN solving a problem that at the time was thought to be insurmountable,
and in the adaptability of its principles to the successful overcoming of
apparently insuperable difficulties subsequently arising in other lines of
work, this invention is one of the most remarkable of the many that Edison
has made in his long career as an inventor.
The object primarily sought to be accomplished was the repeating of
telegraphic signals from a distance without the aid of a galvanometer or an
electromagnetic relay, to overcome the claims of the Page patent referred to
in the preceding narrative. This object was achieved in the device described
in Edison's basic patent No. 158,787, issued January 19, 1875, by the
substitution of friction and anti-friction for the presence and absence of
magnetism in a regulation relay.
It may be observed, parenthetically, for the benefit of the lay reader, that
in telegraphy the device known as the relay is a receiving instrument
containing an electromagnet adapted to respond to the weak line-current. Its
armature moves in accordance with electrical impulses, or signals,
transmitted from a distance, and, in so responding, operates mechanically to
alternately close and open a separate local circuit in which there is a
sounder and a powerful battery. When used for true relaying purposes the
signals received from a distance are in turn repeated over the next section of
the line, the powerful local battery furnishing current for this purpose. As
this causes a loud repetition of the original signals, it will be seen that
relaying is an economic method of extending a telegraph circuit beyond the
natural limits of its battery power.
At the time of Edison's invention, as related in Chapter IX of the
preceding narrative, there existed no other known method than the one just
described for the repetition of transmitted signals, thus limiting the
application of telegraphy to the pleasure of those who might own any patent
controlling the relay, except on simple circuits where a single battery was
sufficient. Edison's previous discovery of differential friction of surfaces
through electrochemical decomposition was now adapted by him to produce
motion at the end of a circuit without the intervention of an electromagnet.

through electrochemical decomposition was now adapted by him to produce
motion at the end of a circuit without the intervention of an electromagnet.
Page 555
In other words, he invented a telegraph instrument having a vibrator
controlled by electrochemical decomposition, to take the place of a
vibrating armature operated by an electromagnet, and thus opened an
entirely new and unsuspected avenue in the art.
Edison's electromotograph comprised an ingeniously arranged apparatus
in which two surfaces, normally in contact with each other, were caused to
alternately adhere by friction or slip by reason of electrochemical
decomposition. One of these surfaces consisted of a small drum or cylinder
of chalk, which was kept in a moistened condition with a suitable chemical
solution, and adapted to revolve continuously by clockwork. The other
surface consisted of a small pad which rested with frictional pressure on the
periphery of the drum. This pad was carried on the end of a vibrating arm
whose lateral movement was limited between two adjustable points.
Normally, the frictional pressure between the drum and pad would carry the
latter with the former as it revolved, but if the friction were removed a
spring on the end of the vibrator arm would draw it back to its starting-
place.
In practice, the chalk drum was electrically connected with one pole of an
incoming telegraph circuit, and the vibrating arm and pad with the other
pole. When the drum rotated, the friction of the pad carried the vibrating
arm forward, but an electrical impulse coming over the line would
decompose the chemical solution with which the drum was moistened,
causing an effect similar to lubrication, and thus allowing the pad to slip
backward freely in response to the pull of its retractile spring. The frictional
movements of the pad with the drum were comparatively long or short, and
corresponded with the length of the impulses sent in over the line. Thus, the
transmission of Morse dots and dashes by the distant operator resulted in
movements of corresponding length by the frictional pad and vibrating arm.
This brings us to the gist of the ingenious way in which Edison
substituted the action of electrochemical decomposition for that of the
electromagnet to operate a relay. The actual relaying was accomplished
through the medium of two contacts making connection with the local or
relay circuit. One of these contacts was fixed, while the other was carried
by the vibrating arm; and, as the latter made its forward and backward
movements, these contacts were alternately brought together or separated,
thus throwing in and out of circuit the battery and sounder in the local
controlled by electrochemical decomposition, to take the place of a
vibrating armature operated by an electromagnet, and thus opened an
entirely new and unsuspected avenue in the art.

thus throwing in and out of circuit the battery and sounder in the local
Page 556
circuit and causing a repetition of the incoming signals. The other side of
the local circuit was permanently connected to an insulated block on the
vibrator. This device not only worked with great rapidity, but was extremely
sensitive, and would respond to currents too weak to affect the most
delicate electromagnetic relay. It should be stated that Edison did not
confine himself to the working of the electromotograph by the slipping of
surfaces through the action of incoming current, but by varying the
character of the surfaces in contact the frictional effect might be intensified
by the electrical current. In such a case the movements would be the reverse
of those above indicated, but the end sought—namely, the relaying of
messages—would be attained with the same certainty.
While the principal object of this invention was to accomplish the
repetition of signals without the aid of an electromagnetic relay, the
instrument devised by Edison was capable of use as a recorder also, by
employing a small wheel inked by a fountain wheel and attached to the
vibrating arm through suitable mechanism. By means of this adjunct the
dashes and dots of the transmitted impulses could be recorded upon a paper
ribbon passing continuously over the drum.
The electromotograph is shown diagrammatically in Figs. 1 and 2, in
plan and vertical section respectively. The reference letters in each case
indicate identical parts: A being the chalk drum, B the paper tape, C the
auxiliary cylinder, D the vibrating arm, E the frictional pad, F the spring, G
and H the two contacts, I and J the two wires leading to local circuit, K a
battery, and L an ordinary telegraph key. The two last named, K and L, are
shown to make the sketch complete but in practice would be at the
transmitting end, which might be hundreds of miles away. It will be
understood, of course, that the electromotograph is a receiving and relaying
instrument.
Another notable use of the electromotograph principle was in its
adaptation to the receiver in Edison's loud-speaking telephone, on which
United States Patent No. 221,957 was issued November 25, 1879. A chalk
cylinder moistened with a chemical solution was revolved by hand or a
small motor. Resting on the cylinder was a palladium-faced pen or spring,
which was attached to a mica diaphragm in a resonator. The current passed
from the main line through the pen to the chalk and to the battery. The
sound-waves impinging upon the distant transmitter varied the resistance of

vibrator. This device not only worked with great rapidity, but was extremely
sensitive, and would respond to currents too weak to affect the most

Page 557
the carbon button therein, thus causing corresponding variations in the
strength of the battery current. These variations, passing through the chalk
cylinder produced more or less electrochemical decomposition, which in
turn caused differences of adhesion between the pen and cylinder and hence
gave rise to mechanical vibrations of the diaphragm by reason of which the
speaker's words were reproduced. Telephones so operated repeated
speaking and singing in very loud tones. In one instance, spoken words and
the singing of songs originating at a distance were heard perfectly by an
audience of over five thousand people.

VI. THE TELEPHONE
ON April 27, 1877, Edison filed in the United States Patent Office an
application for a patent on a telephone, and on May 3, 1892, more than
fifteen years afterward, Patent No. 474,230 was granted thereon. Numerous
other patents have been issued to him for improvements in telephones, but
the one above specified may be considered as the most important of them,
since it is the one that first discloses the principle of the carbon transmitter.
This patent embodies but two claims, which are as follows:
"1. In a speaking-telegraph transmitter, the combination of a metallic
diaphragm and disk of plumbago or equivalent material, the contiguous
faces of said disk and diaphragm being in contact, substantially as
described.
"2. As a means for effecting a varying surface contact in the circuit of a
speaking-telegraph transmitter, the combination of two electrodes, one of
plumbago or similar material, and both having broad surfaces in vibratory
contact with each other, substantially as described."
The advance that was brought about by Edison's carbon transmitter will
be more apparent if we glance first at the state of the art of telephony prior
to his invention.
Bell was undoubtedly the first inventor of the art of transmitting speech
over an electric circuit, but, with his particular form of telephone, the field
was circumscribed. Bell's telephone is shown in the diagrammatic sectional
sketch (Fig. 1).
In the drawing M is a bar magnet contained in the rubber case, L. A
bobbin, or coil of wire, B, surrounds one end of the magnet. A diaphragm of
soft iron is shown at D, and E is the mouthpiece. The wire terminals of the
coil, B, connect with the binding screws, C C.
The next illustration shows a pair of such telephones connected for use,
the working parts only being designated by the above reference letters.
It will be noted that the wire terminals are here put to their proper uses,
two being joined together to form a line of communication, and the other
two being respectively connected to "ground."

Page 559
Now, if we imagine a person at each one of the instruments (Fig. 2) we
shall find that when one of them speaks the sound vibrations impinge upon
the diaphragm and cause it to act as a vibrating armature. By reason of its
vibrations, this diaphragm induces very weak electric impulses in the
magnetic coil. These impulses, according to Bell's theory, correspond in
form to the sound-waves, and, passing over the line, energize the magnet
coil at the receiving end, thus giving rise to corresponding variations in
magnetism by reason of which the receiving diaphragm is similarly vibrated
so as to reproduce the sounds. A single apparatus at each end is therefore
sufficient, performing the double function of transmitter and receiver. It will
be noticed that in this arrangement no battery is used The strength of the
impulses transmitted is therefore limited to that of the necessarily weak
induction currents generated by the original sounds minus any loss arising
by reason of resistance in the line.
Edison's carbon transmitter overcame this vital or limiting weakness by
providing for independent power on the transmission circuit, and by
introducing the principle of varying the resistance of that circuit with
changes in the pressure. With Edison's telephone there is used a closed
circuit on which a battery current constantly flows, and in that circuit is a
pair of electrodes, one or both of which is carbon. These electrodes are
always in contact with a certain initial pressure, so that current will be
always flowing over the circuit. One of the electrodes is connected with the
diaphragm on which the sound-waves impinge, and the vibrations of this
diaphragm cause corresponding variations in pressure between the
electrodes, and thereby effect similar variations in the current which is
passing over the line to the receiving end. This current, flowing around the
receiving magnet, causes corresponding impulses therein, which, acting
upon its diaphragm, effect a reproduction of the original vibrations and
hence of the original sounds.
In other words, the essential difference is that with Bell's telephone the
sound-waves themselves generate the electric impulses, which are therefore
extremely faint. With Edison's telephone the sound-waves simply actuate an
electric valve, so to speak, and permit variations in a current of any desired
strength.
A second distinction between the two telephones is this: With the Bell
apparatus the very weak electric impulses generated by the vibration of the
shall find that when one of them speaks the sound vibrations impinge upon
the diaphragm and cause it to act as a vibrating armature. By reason of its
vibrations, this diaphragm induces very weak electric impulses in the
magnetic coil. These impulses, according to Bell's theory, correspond in
form to the sound-waves, and, passing over the line, energize the magnet
coil at the receiving end, thus giving rise to corresponding variations in
magnetism by reason of which the receiving diaphragm is similarly vibrated
so as to reproduce the sounds. A single apparatus at each end is therefore
sufficient, performing the double function of transmitter and receiver. It will
be noticed that in this arrangement no battery is used The strength of the
impulses transmitted is therefore limited to that of the necessarily weak
induction currents generated by the original sounds minus any loss arising
by reason of resistance in the line.

providing for independent power on the transmission circuit, and by
introducing the principle of varying the resistance of that circuit with

pair of electrodes, one or both of which is carbon. These electrodes are
always in contact with a certain initial pressure, so that current will be
always flowing over the circuit. One of the electrodes is connected with the
diaphragm on which the sound-waves impinge, and the vibrations of this
diaphragm cause corresponding variations in pressure between the
electrodes, and thereby effect similar variations in the current which is
passing over the line to the receiving end. This current, flowing around the
receiving magnet, causes corresponding impulses therein, which, acting
upon its diaphragm, effect a reproduction of the original vibrations and
hence of the original sounds.

sound-waves themselves generate the electric impulses, which are therefore
extremely faint. With Edison's telephone the sound-waves simply actuate an
electric valve, so to speak, and permit variations in a current of any desired
strength.
A second distinction between the two telephones is this: With the Bell
apparatus the very weak electric impulses generated by the vibration of the
Page 560
transmitting diaphragm pass over the entire line to the receiving end, and, in
consequence, the possible length of line is limited to a few miles, even
under ideal conditions. With Edison's telephone the battery current does not
flow on the main line, but passes through the primary circuit of an
induction-coil, from the secondary of which corresponding impulses of
enormously higher potential are sent out on the main line to the receiving
end. In consequence, the line may be hundreds of miles in length. No
modern telephone system is in use to-day that does not use these
characteristic features: the varying resistance and the induction-coil. The
system inaugurated by Edison is shown by the diagram (Fig. 3), in which
the carbon transmitter, the induction-coil, the line, and the distant receiver
are respectively indicated.
In Fig. 4 an early form of the Edison carbon transmitter is represented in
sectional view.
The carbon disk is represented by the black portion, E, near the
diaphragm, A, placed between two platinum plates D and G, which are
connected in the battery circuit, as shown by the lines. A small piece of
rubber tubing, B, is attached to the centre of the metallic diaphragm, and
presses lightly against an ivory piece, F, which is placed directly over one
of the platinum plates. Whenever, therefore, any motion is given to the
diaphragm, it is immediately followed by a corresponding pressure upon the
carbon, and by a change of resistance in the latter, as described above.
It is interesting to note the position which Edison occupies in the
telephone art from a legal standpoint. To this end the reader's attention is
called to a few extracts from a decision of Judge Brown in two suits
brought in the United States Circuit Court, District of Massachusetts, by the
American Bell Telephone Company against the National Telephone
Manufacturing Company, et al., and Century Telephone Company, et al.,
reported in Federal Reporter, 109, page 976, et seq. These suits were
brought on the Berliner patent, which, it was claimed, covered broadly the
electrical transmission of speech by variations of pressure between
opposing electrodes in constant contact. The Berliner patent was declared
invalid, and in the course of a long and exhaustive opinion, in which the
state of art and the work of Bell, Edison, Berliner, and others was fully
discussed, the learned Judge made the following remarks: "The carbon
electrode was the invention of Edison.... Edison preceded Berliner in the
consequence, the possible length of line is limited to a few miles, even

VII. EDISON'S TASIMETER
THIS interesting and remarkable device is one of Edison's many
inventions not generally known to the public at large, chiefly because the
range of its application has been limited to the higher branches of science.
He never applied for a patent on the instrument, but dedicated it to the
public.
The device was primarily intended for use in detecting and measuring
infinitesimal degrees of temperature, however remote, and its conception
followed Edison's researches on the carbon telephone transmitter. Its
principle depends upon the variable resistance of carbon in accordance with
the degree of pressure to which it is subjected. By means of this instrument,
pressures that are otherwise inappreciable and undiscoverable may be
observed and indicated.
The detection of small variations of temperatures is brought about
through the changes which heat or cold will produce in a sensitive material
placed in contact with a carbon button, which is put in circuit with a battery
and delicate galvanometer. In the sketch (Fig. 1) there is illustrated, partly
in section, the form of tasimeter which Edison took with him to Rawlins,
Wyoming, in July, 1878, on the expedition to observe the total eclipse of the
sun.
The substance on whose expansion the working of the instrument
depends is a strip of some material extremely sensitive to heat, such as
vulcanite. shown at A, and firmly clamped at B. Its lower end fits into a slot
in a metal plate, C, which in turn rests upon a carbon button. This latter and
the metal plate are connected in an electric circuit which includes a battery
and a sensitive galvanometer. A vulcanite or other strip is easily affected by
differences of temperature, expanding and contracting by reason of the
minutest changes. Thus, an infinitesimal variation in its length through
expansion or contraction changes the pressure on the carbon and affects the
resistance of the circuit to a corresponding degree, thereby causing a
deflection of the galvanometer; a movement of the needle in one direction
denoting expansion, and in the other contraction. The strip, A, is first put
under a slight pressure, deflecting the needle a few degrees from zero. Any

Page 563
subsequent expansion or contraction of the strip may readily be noted by
further movements of the needle. In practice, and for measurements of a
very delicate nature, the tasimeter is inserted in one arm of a Wheatstone
bridge, as shown at A in the diagram (Fig. 2). The galvanometer is shown at
B in the bridge wire, and at C, D, and E there are shown the resistances in
the other arms of the bridge, which are adjusted to equal the resistance of
the tasimeter circuit. The battery is shown at F. This arrangement tends to
obviate any misleading deflections that might arise through changes in the
battery.
The dial on the front of the instrument is intended to indicate the exact
amount of physical expansion or contraction of the strip. This is ascertained
by means of a micrometer screw, S, which moves a needle, T, in front of the
dial. This screw engages with a second and similar screw which is so
arranged as to move the strip of vulcanite up or down. After a galvanometer
deflection has been obtained through the expansion or contraction of the
strip by reason of a change of temperature, a similar deflection is obtained
mechanically by turning the screw, S, one way or the other. This causes the
vulcanite strip to press more or less upon the carbon button, and thus
produces the desired change in the resistance of the circuit. When the
galvanometer shows the desired deflection, the needle, T, will indicate upon
the dial, in decimal fractions of an inch, the exact distance through which
the strip has been moved.
With such an instrument as the above, Edison demonstrated the existence
of heat in the corona at the above-mentioned total eclipse of the sun, but
exact determinations could not be made at that time, because the tasimeter
adjustment was too delicate, and at the best the galvanometer deflections
were so marked that they could not be kept within the limits of the scale.
The sensitiveness of the instrument may be easily comprehended when it is
stated that the heat of the hand thirty feet away from the cone-like funnel of
the tasimeter will so affect the galvanometer as to cause the spot of light to
leave the scale.
This instrument can also be used to indicate minute changes of moisture
in the air by substituting a strip of gelatine in place of the vulcanite. When
so arranged a moistened piece of paper held several feet away will cause a
minute expansion of the gelatine strip, which effects a pressure on the
further movements of the needle. In practice, and for measurements of a
very delicate nature, the tasimeter is inserted in one arm of a Wheatstone
bridge, as shown at A in the diagram (Fig. 2). The galvanometer is shown at

VIII. THE EDISON PHONOGRAPH
THE first patent that was ever granted on a device for permanently
recording the human voice and other sounds, and for reproducing the same
audibly at any future time, was United States Patent No. 200,251, issued to
Thomas A. Edison on February 19, 1878, the application having been filed
December 24, 1877. It is worthy of note that no references whatever were
cited against the application while under examination in the Patent Office.
This invention therefore, marked the very beginning of an entirely new art,
which, with the new industries attendant upon its development, has since
grown to occupy a position of worldwide reputation.
That the invention was of a truly fundamental character is also evident
from the fact that although all "talking-machines" of to-day differ very
widely in refinement from the first crude but successful phonograph of
Edison, their performance is absolutely dependent upon the employment of
the principles stated by him in his Patent No. 200,251. Quoting from the
specification attached to this patent, we find that Edison said:
"The invention consists in arranging a plate, diaphragm or other flexible
body capable of being vibrated by the human voice or other sounds, in
conjunction with a material capable of registering the movements of such
vibrating body by embossing or indenting or altering such material, in such
a manner that such register marks will be sufficient to cause a second
vibrating plate or body to be set in motion by them, and thus reproduce the
motions of the first vibrating body."
It will be at once obvious that these words describe perfectly the basic
principle of every modern phonograph or other talking-machine,
irrespective of its manufacture or trade name.
Edison's first model of the phonograph is shown in the following
illustration.
It consisted of a metallic cylinder having a helical indenting groove cut
upon it from end to end. This cylinder was mounted on a shaft supported on
two standards. This shaft at one end was fitted with a handle, by means of
which the cylinder was rotated. There were two diaphragms, one on each

Edison's first model of the phonograph is shown in the following
illustration.
It consisted of a metallic cylinder having a helical indenting groove cut
upon it from end to end. This cylinder was mounted on a shaft supported on
two standards. This shaft at one end was fitted with a handle, by means of
which the cylinder was rotated. There were two diaphragms, one on each
Page 566
side of the cylinder, one being for recording and the other for reproducing
speech or other sounds. Each diaphragm had attached to it a needle. By
means of the needle attached to the recording diaphragm, indentations were
made in a sheet of tin-foil stretched over the peripheral surface of the
cylinder when the diaphragm was vibrated by reason of speech or other
sounds. The needle on the other diaphragm subsequently followed these
indentations, thus reproducing the original sounds.
Crude as this first model appears in comparison with machines of later
development and refinement, it embodied their fundamental essentials, and
was in fact a complete, practical phonograph from the first moment of its
operation.
The next step toward the evolution of the improved phonograph of to-day
was another form of tin-foil machine, as seen in the illustration.
It will be noted that this was merely an elaborated form of the first
model, and embodied several mechanical modifications, among which was
the employment of only one diaphragm for recording and reproducing.
Such was the general type of phonograph used for exhibition purposes in
America and other countries in the three or four years immediately
succeeding the date of this invention.
In operating the machine the recording diaphragm was advanced nearly
to the cylinder, so that as the diaphragm was vibrated by the voice the
needle would prick or indent a wave-like record in the tin-foil that was on
the cylinder. The cylinder was constantly turned during the recording, and
in turning, was simultaneously moved forward. Thus the record would be
formed on the tin-foil in a continuous spiral line. To reproduce this record it
was only necessary to again start at the beginning and cause the needle to
retrace its path in the spiral line. The needle, in passing rapidly in contact
with the recorded waves, was vibrated up and down, causing corresponding
vibrations of the diaphragm. In this way sound-waves similar to those
caused by the original sounds would be set up in the air, thus reproducing
the original speech.
The modern phonograph operates in a precisely similar way, the only
difference being in details of refinement. Instead of tin-foil, a wax cylinder
is employed, the record being cut thereon by a cutting-tool attached to a
diaphragm, while the reproduction is effected by means of a blunt stylus
similarly attached.

Page 567
The cutting-tool and stylus are devices made of sapphire, a gem next in
hardness to a diamond, and they have to be cut and formed to an exact
nicety by means of diamond dust, most of the work being performed under
high-powered microscopes. The minute proportions of these devices will be
apparent by a glance at the accompanying illustrations, in which the object
on the left represents a common pin, and the objects on the right the cutting-
tool and reproducing stylus, all actual sizes.
In the next illustration (Fig. 4) there is shown in the upper sketch, greatly
magnified, the cutting or recording tool in the act of forming the record,
being vibrated rapidly by the diaphragm; and in the lower sketch, similarly
enlarged, a representation of the stylus travelling over the record thus made,
in the act of effecting a reproduction.
From the late summer of 1878 and to the fall of 1887 Edison was
intensely busy on the electric light, electric railway, and other problems,
and virtually gave no attention to the phonograph. Hence, just prior to the
latter-named period the instrument was still in its tin-foil age; but he then
began to devote serious attention to the development of an improved type
that should be of greater commercial importance. The practical results are
too well known to call for further comment. That his efforts were not
limited in extent may be inferred from the fact that since the fall of 1887 to
the present writing he has been granted in the United States one hundred
and four patents relating to the phonograph and its accessories.
Interesting as the numerous inventions are, it would be a work of
supererogation to digest all these patents in the present pages, as they
represent not only the inception but also the gradual development and
growth of the wax-record type of phonograph from its infancy to the
present perfected machine and records now so widely known all over the
world. From among these many inventions, however, we will select two or
three as examples of ingenuity and importance in their bearing upon present
perfection of results.
One of the difficulties of reproduction for many years was the trouble
experienced in keeping the stylus in perfect engagement with the wave-like
record, so that every minute vibration would be reproduced. It should be
remembered that the deepest cut of the recording tool is only about one-
third the thickness of tissue-paper. Hence, it will be quite apparent that the
slightest inequality in the surface of the wax would be sufficient to cause
hardness to a diamond, and they have to be cut and formed to an exact
nicety by means of diamond dust, most of the work being performed under
high-powered microscopes. The minute proportions of these devices will be
apparent by a glance at the accompanying illustrations, in which the object
on the left represents a common pin, and the objects on the right the cutting-
tool and reproducing stylus, all actual sizes.

One of the difficulties of reproduction for many years was the trouble
experienced in keeping the stylus in perfect engagement with the wave-like
record, so that every minute vibration would be reproduced. It should be
remembered that the deepest cut of the recording tool is only about one-
third the thickness of tissue-paper. Hence, it will be quite apparent that the
slightest inequality in the surface of the wax would be sufficient to cause
Page 568
false vibration, and thus give rise to distorted effects in such music or other
sounds as were being reproduced. To remedy this, Edison added an
attachment which is called a "floating weight," and is shown at A in the
illustration above.
The function of the floating weight is to automatically keep the stylus in
close engagement with the record, thus insuring accuracy of reproduction.
The weight presses the stylus to its work, but because of its mass it cannot
respond to the extremely rapid vibrations of the stylus. They are therefore
communicated to the diaphragm.
Some of Edison's most remarkable inventions are revealed in a number of
interesting patents relating to the duplication of phonograph records. It
would be obviously impossible, from a commercial standpoint, to obtain a
musical record from a high-class artist and sell such an original to the
public, as its cost might be from one hundred to several thousand dollars.
Consequently, it is necessary to provide some way by which duplicates may
be made cheaply enough to permit their purchase by the public at a
reasonable price.
The making of a perfect original musical or other record is a matter of no
small difficulty, as it requires special technical knowledge and skill
gathered from many years of actual experience; but in the exact copying, or
duplication, of such a record, with its many millions of microscopic waves
and sub-waves, the difficulties are enormously increased. The duplicates
must be microscopically identical with the original, they must be free from
false vibrations or other defects, although both original and duplicates are
of such easily defacable material as wax; and the process must be cheap and
commercial not a scientific laboratory possibility.
For making duplicates it was obviously necessary to first secure a mold
carrying the record in negative or reversed form. From this could be
molded, or cast, positive copies which would be identical with the original.
While the art of electroplating would naturally suggest itself as the means
of making such a mold, an apparently insurmountable obstacle appeared on
the very threshold. Wax, being a non-conductor, cannot be electroplated
unless a conducting surface be first applied. The coatings ordinarily used in
electro-deposition were entirely out of the question on account of
coarseness, the deepest waves of the record being less than one-thousandth
of an inch in depth, and many of them probably ten to one hundred times as
sounds as were being reproduced. To remedy this, Edison added an
attachment which is called a "floating weight," and is shown at A in the
illustration above.
The function of the floating weight is to automatically keep the stylus in
close engagement with the record, thus insuring accuracy of reproduction.

electro-deposition were entirely out of the question on account of
coarseness, the deepest waves of the record being less than one-thousandth
of an inch in depth, and many of them probably ten to one hundred times as
Page 569
shallow. Edison finally decided to apply a preliminary metallic coating of
infinitesimal thinness, and accomplished this object by a remarkable
process known as the vacuous deposit. With this he applied to the original
record a film of gold probably no thicker than one three-hundred-
thousandth of an inch, or several hundred times less than the depth of an
average wave. Three hundred such layers placed one on top of the other
would make a sheet no thicker than tissue-paper.
The process consists in placing in a vacuum two leaves, or electrodes, of
gold, and between them the original record. A constant discharge of
electricity of high tension between the electrodes is effected by means of an
induction-coil. The metal is vaporized by this discharge, and is carried by it
directly toward and deposited upon the original record, thus forming the
minute film of gold above mentioned. The record is constantly rotated until
its entire surface is coated. A sectional diagram of the apparatus (Fig. 6.)
will aid to a clearer understanding of this ingenious process.
After the gold film is formed in the manner described above, a heavy
backing of baser metal is electroplated upon it, thus forming a substantial
mold, from which the original record is extracted by breakage or shrinkage.
Duplicate records in any quantity may now be made from this mold by
surrounding it with a cold-water jacket and dipping it in a molten wax-like
material. This congeals on the record surface just as melted butter would
collect on a cold knife, and when the mold is removed the surplus wax falls
out, leaving a heavy deposit of the material which forms the duplicate
record. Numerous ingenious inventions have been made by Edison
providing for a variety of rapid and economical methods of duplication,
including methods of shrinking a newly made copy to facilitate its quick
removal from the mold; methods of reaming, of forming ribs on the interior,
and for many other important and essential details, which limits of space
will not permit of elaboration. Those mentioned above are but fair examples
of the persistent and effective work he has done to bring the phonograph to
its present state of perfection.
In perusing Chapter X of the foregoing narrative, the reader undoubtedly
noted Edison's clear apprehension of the practical uses of the phonograph,
as evidenced by his prophetic utterances in the article written by him for the
North American Review in June, 1878. In view of the crudity of the
instrument at that time, it must be acknowledged that Edison's foresight, as

instrument at that time, it must be acknowledged that Edison's foresight, as
Page 570
vindicated by later events was most remarkable. No less remarkable was his
intensely practical grasp of mechanical possibilities of future types of the
machine, for we find in one of his early English patents (No. 1644 of 1878)
the disk form of phonograph which, some ten to fifteen years later, was
supposed to be a new development in the art. This disk form was also
covered by Edison's application for a United States patent, filed in 1879.
This application met with some merely minor technical objections in the
Patent Office, and seems to have passed into the "abandoned" class for want
of prosecution, probably because of being overlooked in the tremendous
pressure arising from his development of his electric-lighting system.
IX. THE INCANDESCENT LAMP
ALTHOUGH Edison's contributions to human comfort and progress are
extensive in number and extraordinarily vast and comprehensive in scope
and variety, the universal verdict of the world points to his incandescent
lamp and system of distribution of electrical current as the central and
crowning achievements of his life up to this time. This view would seem
entirely justifiable when we consider the wonderful changes in the
conditions of modern life that have been brought about by the wide-spread
employment of these inventions, and the gigantic industries that have grown
up and been nourished by their world-wide application. That he was in this
instance a true pioneer and creator is evident as we consider the subject, for
the United States Patent No. 223,898, issued to Edison on January 27, 1880,
for an incandescent lamp, was of such fundamental character that it opened
up an entirely new and tremendously important art—the art of incandescent
electric lighting. This statement cannot be successfully controverted, for it
has been abundantly verified after many years of costly litigation. If further
proof were desired, it is only necessary to point to the fact that, after thirty
years of most strenuous and practical application in the art by the keenest
intellects of the world, every incandescent lamp that has ever since been
made, including those of modern days, is still dependent upon the
employment of the essentials disclosed in the above-named patent—
namely, a filament of high resistance enclosed in a sealed glass globe
exhausted of air, with conducting wires passing through the glass.
intensely practical grasp of mechanical possibilities of future types of the
machine, for we find in one of his early English patents (No. 1644 of 1878)
the disk form of phonograph which, some ten to fifteen years later, was
supposed to be a new development in the art. This disk form was also
covered by Edison's application for a United States patent, filed in 1879.
This application met with some merely minor technical objections in the
Patent Office, and seems to have passed into the "abandoned" class for want
of prosecution, probably because of being overlooked in the tremendous
pressure arising from his development of his electric-lighting system.
IX. THE INCANDESCENT LAMP
ALTHOUGH Edison's contributions to human comfort and progress are
extensive in number and extraordinarily vast and comprehensive in scope
and variety, the universal verdict of the world points to his incandescent
lamp and system of distribution of electrical current as the central and
crowning achievements of his life up to this time. This view would seem
entirely justifiable when we consider the wonderful changes in the
conditions of modern life that have been brought about by the wide-spread
employment of these inventions, and the gigantic industries that have grown
up and been nourished by their world-wide application. That he was in this
instance a true pioneer and creator is evident as we consider the subject, for

up an entirely new and tremendously important art—the art of incandescent
electric lighting. This statement cannot be successfully controverted, for it

proof were desired, it is only necessary to point to the fact that, after thirty
years of most strenuous and practical application in the art by the keenest
intellects of the world, every incandescent lamp that has ever since been
made, including those of modern days, is still dependent upon the
employment of the essentials disclosed in the above-named patent—
namely, a filament of high resistance enclosed in a sealed glass globe
exhausted of air, with conducting wires passing through the glass.

An incandescent lamp is such a simple-appearing article—merely a
filament sealed into a glass globe—that its intrinsic relation to the art of
electric lighting is far from being apparent at sight. To the lay mind it would
seem that this must have been THE obvious device to make in order to
obtain electric light by incandescence of carbon or other material. But the
reader has already learned from the preceding narrative that prior to its
invention by Edison such a device was NOT obvious, even to the most
highly trained experts of the world at that period; indeed, it was so far from
being obvious that, for some time after he had completed practical lamps
and was actually lighting them up twenty-four hours a day, such a device
and such a result were declared by these same experts to be an utter
impossibility. For a short while the world outside of Menlo Park held
Edison's claims in derision. His lamp was pronounced a fake, a myth,
possibly a momentary success magnified to the dignity of a permanent
device by an overenthusiastic inventor.
Such criticism, however, did not disturb Edison. He KNEW that he had
reached the goal. Long ago, by a close process of reasoning, he had clearly
seen that the only road to it was through the path he had travelled, and
which was now embodied in the philosophy of his incandescent lamp—
namely, a filament, or carbon, of high resistance and small radiating
surface, sealed into a glass globe exhausted of air to a high degree of
vacuum. In originally committing himself to this line of investigation he
was well aware that he was going in a direction diametrically opposite to
that followed by previous investigators. Their efforts had been confined to
low-resistance burners of large radiating surface for their lamps, but he
realized the utter futility of such devices. The tremendous problems of heat
and the prohibitive quantities of copper that would be required for
conductors for such lamps would be absolutely out of the question in
commercial practice.
He was convinced from the first that the true solution of the problem lay
in a lamp which should have as its illuminating body a strip of material
which would offer such a resistance to the flow of electric current that it
could be raised to a high temperature—incandescence—and be of such
small cross-section that it would radiate but little heat. At the same time
such a lamp must require a relatively small amount of current, in order that
comparatively small conductors could be used, and its burner must be
filament sealed into a glass globe—that its intrinsic relation to the art of
electric lighting is far from being apparent at sight. To the lay mind it would
seem that this must have been THE obvious device to make in order to
obtain electric light by incandescence of carbon or other material. But the

such a lamp must require a relatively small amount of current, in order that
comparatively small conductors could be used, and its burner must be
Page 572
capable of withstanding the necessarily high temperatures without
disintegration.
It is interesting to note that these conceptions were in Edison's mind at an
early period of his investigations, when the best expert opinion was that the
subdivision of the electric current was an ignis fatuus. Hence we quote the
following notes he made, November 15, 1878, in one of the laboratory note-
books:
"A given straight wire having 1 ohm resistance and certain length is
brought to a given degree of temperature by given battery. If the same wire
be coiled in such a manner that but one-quarter of its surface radiates, its
temperature will be increased four times with the same battery, or, one-
quarter of this battery will bring it to the temperature of straight wire. Or the
same given battery will bring a wire whose total resistance is 4 ohms to the
same temperature as straight wire.
"This was actually determined by trial.
"The amount of heat lost by a body is in proportion to the radiating
surface of that body. If one square inch of platina be heated to 100 degrees
it will fall to, say, zero in one second, whereas, if it was at 200 degrees it
would require two seconds.
"Hence, in the case of incandescent conductors, if the radiating surface be
twelve inches and the temperature on each inch be 100, or 1200 for all, if it
is so coiled or arranged that there is but one-quarter, or three inches, of
radiating surface, then the temperature on each inch will be 400. If reduced
to three-quarters of an inch it will have on that three-quarters of an inch
1600 degrees Fahr., notwithstanding the original total amount was but 1200,
because the radiation has been reduced to three-quarters, or 75 units; hence,
the effect of the lessening of the radiation is to raise the temperature of each
remaining inch not radiating to 125 degrees. If the radiating surface should
be reduced to three-thirty-seconds of an inch, the temperature would reach
6400 degrees Fahr. To carry out this law to the best advantage in regard to
platina, etc., then with a given length of wire to quadruple the heat we must
lessen the radiating surface to one-quarter, and to do this in a spiral, three-
quarters must be within the spiral and one-quarter outside for radiating;
hence, a square wire or other means, such as a spiral within a spiral, must
be used. These results account for the enormous temperature of the Electric
Arc with one horse-power; as, for instance, if one horse-power will heat
disintegration.

twelve inches of wire to 1000 degrees Fahr., and this is concentrated to have
one-quarter of the radiating surface, it would reach a temperature of 4000
degrees or sufficient to melt it; but, supposing it infusible, the further
concentration to one-eighth its surface, it would reach a temperature of
16,000 degrees, and to one-thirty-second its surface, which would be about
the radiating surface of the Electric Arc, it would reach 64,000 degrees
Fahr. Of course, when Light is radiated in great quantities not quite these
temperatures would be reached.
"Another curious law is this: It will require a greater initial battery to
bring an iron wire of the same size and resistance to a given temperature
than it will a platina wire in proportion to their specific heats, and in the
case of Carbon, a piece of Carbon three inches long and one-eighth
diameter, with a resistance of 1 ohm, will require a greater battery power to
bring it to a given temperature than a cylinder of thin platina foil of the
same length, diameter, and resistance, because the specific heat of Carbon is
many times greater; besides, if I am not mistaken, the radiation of a
roughened body for heat is greater than a polished one like platina."
Proceeding logically upon these lines of thought and following them out
through many ramifications, we have seen how he at length made a filament
of carbon of high resistance and small radiating surface, and through a
concurrent investigation of the phenomena of high vacua and occluded
gases was able to produce a true incandescent lamp. Not only was it a lamp
as a mere article—a device to give light—but it was also an integral part of
his great and complete system of lighting, to every part of which it bore a
fixed and definite ratio, and in relation to which it was the keystone that
held the structure firmly in place.
The work of Edison on incandescent lamps did not stop at this
fundamental invention, but extended through more than eighteen years of a
most intense portion of his busy life. During that period he was granted one
hundred and forty-nine other patents on the lamp and its manufacture.
Although very many of these inventions were of the utmost importance and
value, we cannot attempt to offer a detailed exposition of them in this
necessarily brief article, but must refer the reader, if interested, to the
patents themselves, a full list being given at the end of this Appendix. The
outline sketch will indicate the principal patents covering the basic features
of the lamp.

The litigation on the Edison lamp patents was one of the most determined
and stubbornly fought contests in the history of modern jurisprudence. Vast
interests were at stake. All of the technical, expert, and professional skill
and knowledge that money could procure or experience devise were availed
of in the bitter fights that raged in the courts for many years. And although
the Edison interests had spent from first to last nearly $2,000,000, and had
only about three years left in the life of the fundamental patent, Edison was
thoroughly sustained as to priority by the decisions in the various suits. We
shall offer a few brief extracts from some of these decisions.
In a suit against the United States Electric Lighting Company, United
States Circuit Court for the Southern District of New York, July 14, 1891,
Judge Wallace said, in his opinion: "The futility of hoping to maintain a
burner in vacuo with any permanency had discouraged prior inventors, and
Mr. Edison is entitled to the credit of obviating the mechanical difficulties
which disheartened them.... He was the first to make a carbon of materials,
and by a process which was especially designed to impart high specific
resistance to it; the first to make a carbon in the special form for the special
purpose of imparting to it high total resistance; and the first to combine
such a burner with the necessary adjuncts of lamp construction to prevent
its disintegration and give it sufficiently long life. By doing these things he
made a lamp which was practically operative and successful, the embryo of
the best lamps now in commercial use, and but for which the subdivision of
the electric light by incandescence would still be nothing but the ignis
fatuus which it was proclaimed to be in 1879 by some of the reamed experts
who are now witnesses to belittle his achievement and show that it did not
rise to the dignity of an invention.... It is impossible to resist the conclusion
that the invention of the slender thread of carbon as a substitute for the
burners previously employed opened the path to the practical subdivision of
the electric light."
An appeal was taken in the above suit to the United States Circuit Court
of Appeals, and on October 4, 1892, the decree of the lower court was
affirmed. The judges (Lacombe and Shipman), in a long opinion reviewed
the facts and the art, and said, inter alia: "Edison's invention was practically
made when he ascertained the theretofore unknown fact that carbon would
stand high temperature, even when very attenuated, if operated in a high
vacuum, without the phenomenon of disintegration. This fact he utilized by
and stubbornly fought contests in the history of modern jurisprudence. Vast
interests were at stake. All of the technical, expert, and professional skill
and knowledge that money could procure or experience devise were availed
of in the bitter fights that raged in the courts for many years. And although

In a suit against the Boston Incandescent Lamp Company et al., in the
United States Circuit Court for the District of Massachusetts, decided in
favor of Edison on June 11, 1894, Judge Colt, in his opinion, said, among
other things: "Edison made an important invention; he produced the first
practical incandescent electric lamp; the patent is a pioneer in the sense of
the patent law; it may be said that his invention created the art of
incandescent electric lighting."
Opinions of other courts, similar in tenor to the foregoing, might be cited,
but it would be merely in the nature of reiteration. The above are sufficient
to illustrate the direct clearness of judicial decision on Edison's position as

X. EDISON'S DYNAMO WORK
AT the present writing, when, after the phenomenally rapid electrical
development of thirty years, we find on the market a great variety of
modern forms of efficient current generators advertised under the names of
different inventors (none, however, bearing the name of Edison), a young
electrical engineer of the present generation might well inquire whether the
great inventor had ever contributed anything to the art beyond a mere TYPE
of machine formerly made and bearing his name, but not now marketed
except second hand.
For adequate information he might search in vain the books usually
regarded as authorities on the subject of dynamo-electric machinery, for
with slight exceptions there has been a singular unanimity in the omission
of writers to give Edison credit for his great and basic contributions to
heavy-current technics, although they have been universally acknowledged
by scientific and practical men to have laid the foundation for the efficiency
of, and to be embodied in all modern generators of current.
It might naturally be expected that the essential facts of Edison's work
would appear on the face of his numerous patents on dynamo-electric
machinery, but such is not necessarily the case, unless they are carefully
studied in the light of the state of the art as it existed at the time. While
some of these patents (especially the earlier ones) cover specific devices
embodying fundamental principles that not only survive to the present day,
but actually lie at the foundation of the art as it now exists, there is no
revelation therein of Edison's preceding studies of magnets, which extended
over many years, nor of his later systematic investigations and deductions.
Dynamo-electric machines of a primitive kind had been invented and
were in use to a very limited extent for arc lighting and electroplating for
some years prior to the summer of 1819, when Edison, with an embryonic
lighting SYSTEM in mind, cast about for a type of machine technically and
commercially suitable for the successful carrying out of his plans. He found
absolutely none. On the contrary, all of the few types then obtainable were
uneconomical, indeed wasteful, in regard to efficiency. The art, if indeed
there can be said to have been an art at that time, was in chaotic confusion,

Page 577
and only because of Edison's many years' study of the magnet was he
enabled to conclude that insufficiency in quantity of iron in the magnets of
such machines, together with poor surface contacts, rendered the cost of
magnetization abnormally high. The heating of solid armatures, the only
kind then known, and poor insulation in the commutators, also gave rise to
serious losses. But perhaps the most serious drawback lay in the high-
resistance armature, based upon the highest scientific dictum of the time
that in order to obtain the maximum amount of work from a machine, the
internal resistance of the armature must equal the resistance of the exterior
circuit, although the application of this principle entailed the useless
expenditure of at least 50 per cent. of the applied energy.
It seems almost incredible that only a little over thirty years ago the sum
of scientific knowledge in regard to dynamo-electric machines was so
meagre that the experts of the period should settle upon such a dictum as
this, but such was the fact, as will presently appear. Mechanical generators
of electricity were comparatively new at that time; their theory and practice
were very imperfectly understood; indeed, it is quite within the bounds of
truth to say that the correct principles were befogged by reason of the lack
of practical knowledge of their actual use. Electricians and scientists of the
period had been accustomed for many years past to look to the chemical
battery as the source from which to obtain electrical energy; and in the
practical application of such energy to telegraphy and kindred uses, much
thought and ingenuity had been expended in studying combinations of
connecting such cells so as to get the best results. In the text-books of the
period it was stated as a settled principle that, in order to obtain the
maximum work out of a set of batteries, the internal resistance must
approximately equal the resistance of the exterior circuit. This principle and
its application in practice were quite correct as regards chemical batteries,
but not as regards dynamo machines. Both were generators of electrical
current, but so different in construction and operation, that rules applicable
to the practical use of the one did not apply with proper commercial
efficiency to the other. At the period under consideration, which may be
said to have been just before dawn of the day of electric light, the
philosophy of the dynamo was seen only in mysterious, hazy outlines—just
emerging from the darkness of departing night. Perhaps it is not surprising,
then, that the dynamo was loosely regarded by electricians as the practical
equivalent of a chemical battery; that many of the characteristics of
enabled to conclude that insufficiency in quantity of iron in the magnets of
such machines, together with poor surface contacts, rendered the cost of
magnetization abnormally high. The heating of solid armatures, the only

Page 578
performance of the chemical cell were also attributed to it, and that if the
maximum work could be gotten out of a set of batteries when the internal
and external resistances were equal (and this was commercially the best
thing to do), so must it be also with a dynamo.
It was by no miracle that Edison was far and away ahead of his time
when he undertook to improve the dynamo. He was possessed of absolute
KNOWLEDGE far beyond that of his contemporaries. This he ad acquired
by the hardest kind of work and incessant experiment with magnets of all
kinds during several years preceding, particularly in connection with his
study of automatic telegraphy. His knowledge of magnets was tremendous.
He had studied and experimented with electromagnets in enormous variety,
and knew their peculiarities in charge and discharge, lag, self-induction,
static effects, condenser effects, and the various other phenomena connected
therewith. He had also made collateral studies of iron, steel, and copper,
insulation, winding, etc. Hence, by reason of this extensive work and
knowledge, Edison was naturally in a position to realize the utter
commercial impossibility of the then best dynamo machine in existence,
which had an efficiency of only about 40 per cent., and was constructed on
the "cut-and-try" principle.
He was also naturally in a position to assume the task he set out to
accomplish, of undertaking to plan and-build an improved type of machine
that should be commercial in having an efficiency of at least 90 per cent.
Truly a prodigious undertaking in those dark days, when from the
standpoint of Edison's large experience the most practical and correct
electrical treatise was contained in the Encyclopaedia Britannica, and in a
German publication which Mr. Upton had brought with him after he had
finished his studies with the illustrious Helmholtz. It was at this period that
Mr. Upton commenced his association with Edison, bringing to the great
work the very latest scientific views and the assistance of the higher
mathematics, to which he had devoted his attention for several years
previously.
As some account of Edison's investigations in this connection has already
been given in Chapter XII of the narrative, we shall not enlarge upon them
here, but quote from An Historical Review, by Charles L. Clarke,
Laboratory Assistant at Menlo Park, 1880-81; Chief Engineer of the Edison
Electric Light Company, 1881-84:
maximum work could be gotten out of a set of batteries when the internal
and external resistances were equal (and this was commercially the best
thing to do), so must it be also with a dynamo.

"In June, 1879, was published the account of the Edison dynamo-electric
machine that survived in the art. This machine went into extensive
commercial use, and was notable for its very massive and powerful field-
magnets and armature of extremely low resistance as compared with the
combined external resistance of the supply-mains and lamps. By means of
the large masses of iron in the field-magnets, and closely fitted joints
between the several parts thereof, the magnetic resistance (reluctance) of
the iron parts of the magnetic circuit was reduced to a minimum, and the
required magnetization effected with the maximum economy. At the same
time Mr. Edison announced the commercial necessity of having the
armature of the dynamo of low resistance, as compared with the external
resistance, in order that a large percentage of the electrical energy
developed should be utilized in the lamps, and only a small percentage lost
in the armature, albeit this procedure reduced the total generating capacity
of the machine. He also proposed to make the resistance of the supply-
mains small, as compared with the combined resistance of the lamps in
multiple arc, in order to still further increase the percentage of energy
utilized in the lamps. And likewise to this end the combined resistance of
the generator armatures in multiple arc was kept relatively small by
adjusting the number of generators operating in multiple at any time to the
number of lamps then in use. The field-magnet circuits of the dynamos
were connected in multiple with a separate energizing source; and the field-
current; and strength of field, were regulated to maintain the required
amount of electromotive force upon the supply-mains under all conditions
of load from the maximum to the minimum number of lamps in use, and to
keep the electromotive force of all machines alike."
Among the earliest of Edison's dynamo experiments were those relating
to the core of the armature. He realized at once that the heat generated in a
solid core was a prolific source of loss. He experimented with bundles of
iron wires variously insulated, also with sheet-iron rolled cylindrically and
covered with iron wire wound concentrically. These experiments and many
others were tried in a great variety of ways, until, as the result of all this
work, Edison arrived at the principle which has remained in the art to this
day. He split up the iron core of the armature into thin laminations,
separated by paper, thus practically suppressing Foucault currents therein
and resulting heating effect. It was in his machine also that mica was used
for the first time as an insulating medium in a commutator. [27]

Elementary as these principles will appear to the modern student or
engineer, they were denounced as nothing short of absurdity at the time of
their promulgation—especially so with regard to Edison's proposal to upset
the then settled dictum that the armature resistance should be equal to the
external resistance. His proposition was derided in the technical press of the
period, both at home and abroad. As public opinion can be best illustrated
by actual quotation, we shall present a characteristic instance.
In the Scientific American of October 18, 1879, there appeared an
illustrated article by Mr. Upton on Edison's dynamo machine, in which
Edison's views and claims were set forth. A subsequent issue contained a
somewhat acrimonious letter of criticism by a well-known maker of
dynamo machines. At the risk of being lengthy, we must quote nearly all
this letter: "I can scarcely conceive it as possible that the article on the
above subject '(Edison's Electric Generator)' in last week's Scientific
American could have been written from statements derived from Mr.
Edison himself, inasmuch as so many of the advantages claimed for the
machine described and statements of the results obtained are so manifestly
absurd as to indicate on the part of both writer and prompter a positive want
of knowledge of the electric circuit and the principles governing the
construction and operation of electric machines.
"It is not my intention to criticise the design or construction of the
machine (not because they are not open to criticism), as I am now and have
been for many years engaged in the manufacture of electric machines, but
rather to call attention to the impossibility of obtaining the described results
without destroying the doctrine of the conservation and correlation of
forces.

"It is stated that 'the internal resistance of the armature' of this machine 'is
only 1/2 ohm.' On this fact and the disproportion between this resistance
and that of the external circuit, the theory of the alleged efficiency of the

Page 581
useful work nearly double the number of foot-pounds that any other
machine will under like conditions.'" The writer of this critical letter then
proceeds to quote Mr. Upton's statement of this efficiency: "'Now the
energy converted is distributed over the whole resistance, hence if the
resistance of the machine be represented by 1 and the exterior circuit by 9,
then of the total energy converted nine-tenths will be useful, as it is outside
of the machine, and one-tenth is lost in the resistance of the machine.'"
After this the critic goes on to say:
"How any one acquainted with the laws of the electric circuit can make
such statements is what I cannot understand. The statement last quoted is
mathematically absurd. It implies either that the machine is CAPABLE OF
INCREASING ITS OWN ELECTROMOTIVE FORCE NINE TIMES
WITHOUT AN INCREASED EXPENDITURE OF POWER, or that
external resistance is NOT resistance to the current induced in the Edison
machine.
"Does Mr. Edison, or any one for him, mean to say that r/n enables him
to obtain nE, and that C IS NOT = E / (r/n + R)? If so Mr. Edison has
discovered something MORE than perpetual motion, and Mr. Keely had
better retire from the field.
"Further on the writer (Mr. Upton) gives us another example of this mode
of reasoning when, emboldened and satisfied with the absurd theory above
exposed, he endeavors to prove the cause of the inefficiency of the Siemens
and other machines. Couldn't the writer of the article see that since C = E/(r
+ R) that by R/n or by making R = r, the machine would, according to his
theory, have returned more useful current to the circuit than could be due to
the power employed (and in the ratio indicated), so that there would
actually be a creation of force! . . . .
"In conclusion allow me to say that if Mr Edison thinks he has
accomplished so much by the REDUCTION OF THE INTERNAL
RESISTANCE of his machine, that he has much more to do in this direction
before his machine will equal IN THIS RESPECT others already in the
market."
Another participant in the controversy on Edison's generator was a
scientific gentleman, who in a long article published in the Scientific
American, in November, 1879, gravely undertook to instruct Edison in the
A B C of electrical principles, and then proceeded to demonstrate
machine will under like conditions.'" The writer of this critical letter then
proceeds to quote Mr. Upton's statement of this efficiency: "'Now the

Page 582
mathematically the IMPOSSIBILITY of doing WHAT EDISON HAD
ACTUALLY DONE. This critic concludes with a gentle rebuke to the
inventor for ill-timed jesting, and a suggestion to furnish AUTHENTIC
information!
In the light of facts, as they were and are, this article is so full of humor
that we shall indulge in a few quotations It commences in A B C fashion as
follows: "Electric machines convert mechanical into electrical energy.... The
ratio of yield to consumption is the expression of the efficiency of the
machine.... How many foot-pounds of electricity can be got out of 100 foot-
pounds of mechanical energy? Certainly not more than 100: certainly less....
The facts and laws of physics, with the assistance of mathematical logic,
never fail to furnish precious answers to such questions."
The would-be critic then goes on to tabulate tests of certain other dynamo
machines by a committee of the Franklin Institute in 1879, the results of
which showed that these machines returned about 50 per cent. of the
applied mechanical energy, ingenuously remarking: "Why is it that when
we have produced the electricity, half of it must slip away? Some persons
will be content if they are told simply that it is a way which electricity has
of behaving. But there is a satisfactory rational explanation which I believe
can be made plain to persons of ordinary intelligence. It ought to be known
to all those who are making or using machines. I am grieved to observe that
many persons who talk and write glibly about electricity do not understand
it; some even ignore or deny the fact to be explained."
Here follows HIS explanation, after which he goes on to say: "At this
point plausibly comes in a suggestion that the internal part of the circuit be
made very small and the external part very large. Why not (say) make the
internal part 1 and the external 9, thus saving nine-tenths and losing only
one-tenth? Unfortunately, the suggestion is not practical; a fallacy is
concealed in it."
He then goes on to prove his case mathematically, to his own satisfaction,
following it sadly by condoling with and a warning to Edison: "But about
Edison's electric generator! . . . No one capable of making the
improvements in the telegraph and telephone, for which we are indebted to
Mr. Edison, could be other than an accomplished electrician. His reputation
as a scientist, indeed, is smirched by the newspaper exaggerations, and no

took up the question on his side, and answered the critics by further
elucidations of the principles on which Edison had founded such
remarkable and radical improvements in the art. The type of Edison's first

in 1880 ten dynamos of eight horse-power each were driven by a slow-

Page 584
substituting a single large dynamo for the several small dynamos, and
directly coupling it with the driving engine, and at the same time preserve
the requisite high armature speed by using an engine of the high-speed type.
He also expected to realize still further gains in economy from the use of a
large dynamo in place of several small machines by a more than
correspondingly lower armature resistance, less energy for magnetizing the
field, and for other minor reasons. To the same end, he intended to supply
steam to the engine under a much higher boiler pressure than was
customary in stationary-engine driving at that time."
The construction of the first one of these large machines was commenced
late in the year 1880. Early in 1881 it was completed and tested, but some
radical defects in armature construction were developed, and it was also
demonstrated that a rate of engine speed too high for continuously safe and
economical operation had been chosen. The machine was laid aside. An
accurate illustration of this machine, as it stood in the engine-room at
Menlo Park, is given in Van Nostrand's Engineering Magazine, Vol. XXV,
opposite page 439, and a brief description is given on page 450.
With the experience thus gained, Edison began, in the spring of 1881, at
the Edison Machine Works, Goerck Street, New York City, the construction
of the first successful machine of this type. This was the great machine
known as "Jumbo No. 1," which is referred to in the narrative as having
been exhibited at the Paris International Electrical Exposition, where it was
regarded as the wonder of the electrical world. An intimation of some of the
tremendous difficulties encountered in the construction of this machine has
already been given in preceding pages, hence we shall not now enlarge on
the subject, except to note in passing that the terribly destructive effects of
the spark of self-induction and the arcing following it were first manifested
in this powerful machine, but were finally overcome by Edison after a
strenuous application of his powers to the solution of the problem.
It may be of interest, however, to mention some of its dimensions and
electrical characteristics, quoting again from Mr. Clarke: "The field-magnet
had eight solid cylindrical cores, 8 inches in diameter and 57 inches long,
upon each of which was wound an exciting-coil of 3.2 ohms resistance,
consisting of 2184 turns of No. 10 B. W. G. insulated copper wire, disposed
in six layers. The laminated iron core of the armature, formed of thin iron
disks, was 33 3/4 inches long, and had an internal diameter of 12 1/2 inches,
directly coupling it with the driving engine, and at the same time preserve
the requisite high armature speed by using an engine of the high-speed type.

shaft. The field-poles were 33 3/4 inches long, and 27 1/2 inches inside
diameter The armature winding consisted of 146 copper bars on the face of
the core, connected into a closed-coil winding by means of 73 copper disks
at each end of the core. The cross-sectional area of each bar was 0.2 square
inch their average length was 42.7 inches, and the copper end-disks were
0.065 inch thick. The commutator had 73 sections. The armature resistance
was 0.0092 ohm, [28] of which 0.0055 ohm was in the armature bars and

was still further reduced to 0.0039 ohm.
Edison's clear insight into the future, as illustrated by his persistent
advocacy of large direct-connected generating units, is abundantly
vindicated by present-day practice. His Jumbo machines, of 175 horse-
power, so enormous for their time, have served as prototypes, and have
been succeeded by generators which have constantly grown in size and
capacity until at this time (1910) it is not uncommon to employ such
shaft. The field-poles were 33 3/4 inches long, and 27 1/2 inches inside
diameter The armature winding consisted of 146 copper bars on the face of
the core, connected into a closed-coil winding by means of 73 copper disks
at each end of the core. The cross-sectional area of each bar was 0.2 square
inch their average length was 42.7 inches, and the copper end-disks were
0.065 inch thick. The commutator had 73 sections. The armature resistance
was 0.0092 ohm, [28] of which 0.0055 ohm was in the armature bars and
0.0037 ohm in the end-disks." An illustration of the next latest type of this

We have not entered into specific descriptions of the many other forms of
dynamo machines invented by Edison, such as the multipolar, the disk
dynamo, and the armature with two windings, for sub-station distribution;
indeed, it is not possible within our limited space to present even a brief
digest of Edison's great and comprehensive work on the dynamo-electric
machine, as embodied in his extensive experiments and in over one hundred
patents granted to him. We have, therefore, confined ourselves to the
indication of a few salient and basic features, leaving it to the interested
student to examine the patents and the technical literature of the long period
of time over which Edison's labors were extended.
Although he has not given any attention to the subject of generators for
many years, an interesting instance of his incisive method of overcoming
minor difficulties occurred while the present volumes were under
preparation (1909). Carbon for commutator brushes has been superseded by
graphite in some cases, the latter material being found much more
advantageous, electrically. Trouble developed, however, for the reason that
while carbon was hard and would wear away the mica insulation
simultaneously with the copper, graphite, being softer, would wear away
only the copper, leaving ridges of mica and thus causing sparking through
unequal contact. At this point Edison was asked to diagnose the trouble and
provide a remedy. He suggested the cutting out of the mica pieces almost to
the bottom, leaving the commutator bars separated by air-spaces. This
scheme was objected to on the ground that particles of graphite would fill
these air-spaces and cause a short-circuit. His answer was that the air-spaces
constituted the value of his plan, as the particles of graphite falling into
them would be thrown out by the action of centrifugal force as the
commutator revolved. And thus it occurred as a matter of fact, and the
trouble was remedied. This idea was subsequently adopted by a great
manufacturer of generators.

XI. THE EDISON FEEDER SYSTEM
TO quote from the preamble of the specifications of United States Patent
No. 264,642, issued to Thomas A. Edison September 19, 1882: "This
invention relates to a method of equalizing the tension or 'pressure' of the
current through an entire system of electric lighting or other translation of
electric force, preventing what is ordinarily known as a 'drop' in those
portions of the system the more remote from the central station...."
The problem which was solved by the Edison feeder system was that
relating to the equal distribution of current on a large scale over extended
areas, in order that a constant and uniform electrical pressure could be
maintained in every part of the distribution area without prohibitory
expenditure for copper for mains and conductors.
This problem had a twofold aspect, although each side was inseparably
bound up in the other. On the one hand it was obviously necessary in a
lighting system that each lamp should be of standard candle-power, and
capable of interchangeable use on any part of the system, giving the same
degree of illumination at every point, whether near to or remote from the
source of electrical energy. On the other hand, this must be accomplished by
means of a system of conductors so devised and arranged that while they
would insure the equal pressure thus demanded, their mass and consequent
cost would not exceed the bounds of practical and commercially
economical investment.
The great importance of this invention can be better understood and
appreciated by a brief glance at the state of the art in 1878-79, when Edison
was conducting the final series of investigations which culminated in his
invention of the incandescent lamp and SYSTEM of lighting. At this time,
and for some years previously, the scientific world had been working on the
"subdivision of the electric light," as it was then termed. Some leading
authorities pronounced it absolutely impossible of achievement on any
extended scale, while a very few others, of more optimistic mind, could see
no gleam of light through the darkness, but confidently hoped for future
developments by such workers as Edison.

Page 589
The earlier investigators, including those up to the period above named,
thought of the problem as involving the subdivision of a FIXED UNIT of
current, which, being sufficient to cause illumination by one large lamp,
might be divided into a number of small units whose aggregate light would
equal the candle-power of this large lamp. It was found, however, in their
experiments that the contrary effect was produced, for with every additional
lamp introduced in the circuit the total candle-power decreased instead of
increasing. If they were placed in series the light varied inversely as the
SQUARE of the number of lamps in circuit; while if they were inserted in
multiple arc, the light diminished as the CUBE of the number in circuit.
[29] The idea of maintaining a constant potential and of PROPORTIONING
THE CURRENT to the number of lamps in circuit did not occur to most of
these early investigators as a feasible method of overcoming the supposed
difficulty.
[Footnote 29: M. Fontaine, in his book on Electric Lighting
(1877), showed that with the current of a battery composed
of sixteen elements, one lamp gave an illumination equal to
54 burners; whereas two similar lamps, if introduced in
parallel or multiple arc, gave the light of only 6 1/2
burners in all; three lamps of only 2 burners in all; four
lamps of only 3/4 of one burner, and five lamps of 1/4 of a
burner.]
It would also seem that although the general method of placing
experimental lamps in multiple arc was known at this period, the idea of
"drop" of electrical pressure was imperfectly understood, if, indeed, realized
at all, as a most important item to be considered in attempting the solution
of the problem. As a matter of fact, the investigators preceding Edison do
not seem to have conceived the idea of a "system" at all; hence it is not
surprising to find them far astray from the correct theory of subdivision of
the electric current. It may easily be believed that the term "subdivision"
was a misleading one to these early experimenters. For a very short time
Edison also was thus misled, but as soon as he perceived that the problem
was one involving the MULTIPLICATION OF CURRENT UNITS, his
broad conception of a "system" was born.
Generally speaking, all conductors of electricity offer more or less
resistance to the passage of current through them and in the technical
terminology of electrical science the word "drop" (when used in reference
to a system of distribution) is used to indicate a fall or loss of initial
thought of the problem as involving the subdivision of a FIXED UNIT of
current, which, being sufficient to cause illumination by one large lamp,
might be divided into a number of small units whose aggregate light would
equal the candle-power of this large lamp. It was found, however, in their

resistance to the passage of current through them and in the technical
terminology of electrical science the word "drop" (when used in reference
to a system of distribution) is used to indicate a fall or loss of initial
Page 590
electrical pressure arising from the resistance offered by the copper
conductors leading from the source of energy to the lamps. The result of
this resistance is to convert or translate a portion of the electrical energy
into another form—namely, heat, which in the conductors is USELESS and
wasteful and to some extent inevitable in practice, but is to be avoided and
remedied as far as possible.
It is true that in an electric-lighting system there is also a fall or loss of
electrical pressure which occurs in overcoming the much greater resistance
of the filament in an incandescent lamp. In this case there is also a
translation of the energy, but here it accomplishes a USEFUL purpose, as
the energy is converted into the form of light through the incandescence of
the filament. Such a conversion is called "work" as distinguished from
"drop," although a fall of initial electrical pressure is involved in each case.
The percentage of "drop" varies according to the quantity of copper used
in conductors, both as to cross-section and length. The smaller the cross-
sectional area, the greater the percentage of drop. The practical effect of this
drop would be a loss of illumination in the lamps as we go farther away
from the source of energy. This may be illustrated by a simple diagram in
which G is a generator, or source of energy, furnishing current at a potential
or electrical pressure of 110 volts; 1 and 2 are main conductors, from which
110-volt lamps, L, are taken in derived circuits. It will be understood that
the circuits represented in Fig. 1 are theoretically supposed to extend over a
large area. The main conductors are sufficiently large in cross-section to
offer but little resistance in those parts which are comparatively near the
generator, but as the current traverses their extended length there is a
gradual increase of resistance to overcome, and consequently the drop
increases, as shown by the figures. The result of the drop in such a case
would be that while the two lamps, or groups, nearest the generator would
be burning at their proper degree of illumination, those beyond would give
lower and lower candle-power, successively, until the last lamp, or group,
would be giving only about two-thirds the light of the first two. In other
words, a very slight drop in voltage means a disproportionately great loss in
illumination. Hence, by using a primitive system of distribution, such as
that shown by Fig. 1, the initial voltage would have to be so high, in order
to obtain the proper candle-power at the end of the circuit, that the lamps
nearest the generator would be dangerously overheated. It might be
suggested as a solution of this problem that lamps of different voltages
conductors leading from the source of energy to the lamps. The result of
this resistance is to convert or translate a portion of the electrical energy
into another form—namely, heat, which in the conductors is USELESS and
wasteful and to some extent inevitable in practice, but is to be avoided and
remedied as far as possible.

to obtain the proper candle-power at the end of the circuit, that the lamps
nearest the generator would be dangerously overheated. It might be
suggested as a solution of this problem that lamps of different voltages
Page 591
could be used. But, as we are considering systems of extended distribution
employing vast numbers of lamps (as in New York City, where millions are
in use), it will be seen that such a method would lead to inextricable
confusion, and therefore be absolutely out of the question. Inasmuch as the
percentage of drop decreases in proportion to the increased cross-section of
the conductors, the only feasible plan would seem to be to increase their
size to such dimensions as to eliminate the drop altogether, beginning with
conductors of large cross-section and tapering off as necessary. This would,
indeed, obviate the trouble, but, on the other hand, would give rise to a
much more serious difficulty—namely, the enormous outlay for copper; an
outlay so great as to be absolutely prohibitory in considering the electric
lighting of large districts, as now practiced.
Another diagram will probably make this more clear. The reference
figures are used as before, except that the horizontal lines extending from
square marked G represent the main conductors. As each lamp requires and
takes its own proportion of the total current generated, it is obvious that the
size of the conductors to carry the current for a number of lamps must be as
large as the sum of ALL the separate conductors which would be required to
carry the necessary amount of current to each lamp separately. Hence, in a
primitive multiple-arc system, it was found that the system must have
conductors of a size equal to the aggregate of the individual conductors
necessary for every lamp. Such conductors might either be separate, as
shown above (Fig. 2), or be bunched together, or made into a solid tapering
conductor, as shown in the following figure:
The enormous mass of copper needed in such a system can be better
appreciated by a concrete example. Some years ago Mr. W. J. Jenks made a
comparative calculation which showed that such a system of conductors
(known as the "Tree" system), to supply 8640 lamps in a territory extending
over so small an area as nine city blocks, would require 803,250 pounds of
copper, which at the then price of 25 cents per pound would cost
$200,812.50!
Such, in brief, was the state of the art, generally speaking, at the period
above named (1878-79). As early in the art as the latter end of the year
1878, Edison had developed his ideas sufficiently to determine that the
problem of electric illumination by small units could be solved by using
incandescent lamps of high resistance and small radiating surface, and by
employing vast numbers of lamps (as in New York City, where millions are
in use), it will be seen that such a method would lead to inextricable
confusion, and therefore be absolutely out of the question. Inasmuch as the
percentage of drop decreases in proportion to the increased cross-section of
the conductors, the only feasible plan would seem to be to increase their
size to such dimensions as to eliminate the drop altogether, beginning with
conductors of large cross-section and tapering off as necessary. This would,

1878, Edison had developed his ideas sufficiently to determine that the
problem of electric illumination by small units could be solved by using
incandescent lamps of high resistance and small radiating surface, and by
Page 592
distributing currents of constant potential thereto in multiple arc by means
of a ramification of conductors, starting from a central source and
branching therefrom in every direction. This was an equivalent of the
method illustrated in Fig. 3, known as the "Tree" system, and was, in fact,
the system used by Edison in the first and famous exhibition of his electric
light at Menlo Park around the Christmas period of 1879. He realized,
however, that the enormous investment for copper would militate against
the commercial adoption of electric lighting on an extended scale. His next
inventive step covered the division of a large city district into a number of
small sub-stations supplying current through an interconnected network of
conductors, thus reducing expenditure for copper to some extent, because
each distribution unit was small and limited the drop.
His next development was the radical advancement of the state of the art
to the feeder system, covered by the patent now under discussion. This
invention swept away the tree and other systems, and at one bound brought
into being the possibility of effectively distributing large currents over
extended areas with a commercially reasonable investment for copper.
The fundamental principles of this invention were, first, to sever entirely
any direct connection of the main conductors with the source of energy;
and, second, to feed current at a constant potential to central points in such
main conductors by means of other conductors, called "feeders," which
were to be connected directly with the source of energy at the central
station. This idea will be made more clear by reference to the following
simple diagram, in which the same letters are used as before, with
additions:
In further elucidation of the diagram, it may be considered that the mains
are laid in the street along a city block, more or less distant from the station,
while the feeders are connected at one end with the source of energy at the
station, their other extremities being connected to the mains at central
points of distribution. Of course, this system was intended to be applied in
every part of a district to be supplied with current, separate sets of feeders
running out from the station to the various centres. The distribution mains
were to be of sufficiently large size that between their most extreme points
the loss would not be more than 3 volts. Such a slight difference would not
make an appreciable variation in the candle-power of the lamps.

make an appreciable variation in the candle-power of the lamps.
Page 593
By the application of these principles, the inevitable but useless loss, or
"drop," required by economy might be incurred, but was LOCALIZED IN
THE FEEDERS, where it would not affect the uniformity of illumination of
the lamps in any of the circuits, whether near to or remote from the station,
because any variations of loss in the feeders would not give rise to similar
fluctuations in any lamp circuit. The feeders might be operated at any
desired percentage of loss that would realize economy in copper, so long as
they delivered current to the main conductors at the potential represented by
the average voltage of the lamps.
Thus the feeders could be made comparatively small in cross-section. It
will be at once appreciated that, inasmuch as the mains required to be laid
ONLY along the blocks to be lighted, and were not required to be run all the
way to the central station (which might be half a mile or more away), the
saving of copper by Edison's feeder system was enormous. Indeed, the
comparative calculation of Mr. Jenks, above referred to, shows that to
operate the same number of lights in the same extended area of territory, the
feeder system would require only 128,739 pounds of copper, which, at the
then price of 25 cents per pound, would cost only $39,185, or A SAVING of
$168,627.50 for copper in this very small district of only nine blocks.
An additional illustration, appealing to the eye, is presented in the
following sketch, in which the comparative masses of copper of the tree and
feeder systems for carrying the same current are shown side by side:
"drop," required by economy might be incurred, but was LOCALIZED IN
THE FEEDERS, where it would not affect the uniformity of illumination of
the lamps in any of the circuits, whether near to or remote from the station,
because any variations of loss in the feeders would not give rise to similar
fluctuations in any lamp circuit. The feeders might be operated at any
desired percentage of loss that would realize economy in copper, so long as
they delivered current to the main conductors at the potential represented by
the average voltage of the lamps.
Thus the feeders could be made comparatively small in cross-section. It
will be at once appreciated that, inasmuch as the mains required to be laid
ONLY along the blocks to be lighted, and were not required to be run all the
way to the central station (which might be half a mile or more away), the
saving of copper by Edison's feeder system was enormous. Indeed, the
comparative calculation of Mr. Jenks, above referred to, shows that to
operate the same number of lights in the same extended area of territory, the
feeder system would require only 128,739 pounds of copper, which, at the
then price of 25 cents per pound, would cost only $39,185, or A SAVING of
$168,627.50 for copper in this very small district of only nine blocks.
An additional illustration, appealing to the eye, is presented in the
following sketch, in which the comparative masses of copper of the tree and
feeder systems for carrying the same current are shown side by side:

XII. THE THREE-WIRE SYSTEM
THIS invention is covered by United States Patent No. 274,290, issued to
Edison on March 20, 1883. The object of the invention was to provide for
increased economy in the quantity of copper employed for the main
conductors in electric light and power installations of considerable extent at
the same time preserving separate and independent control of each lamp,
motor, or other translating device, upon any one of the various distribution
circuits.
Immediately prior to this invention the highest state of the art of
electrical distribution was represented by Edison's feeder system, which has
already been described as a straight parallel or multiple-arc system wherein
economy of copper was obtained by using separate sets of conductors—
minus load—feeding current at standard potential or electrical pressure into
the mains at centres of distribution.
It should be borne in mind that the incandescent lamp which was
accepted at the time as a standard (and has so remained to the present day)
was a lamp of 110 volts or thereabouts. In using the word "standard,"
therefore, it is intended that the same shall apply to lamps of about that
voltage, as well as to electrical circuits of the approximate potential to
operate them.
Briefly stated, the principle involved in the three-wire system is to
provide main circuits of double the standard potential, so as to operate
standard lamps, or other translating devices, in multiple series of two to
each series; and for the purpose of securing independent, individual control
of each unit, to divide each main circuit into any desired number of derived
circuits of standard potential (properly balanced) by means of a central
compensating conductor which would be normally neutral, but designed to
carry any minor excess of current that might flow by reason of any
temporary unbalancing of either side of the main circuit.
Reference to the following diagrams will elucidate this principle more
clearly than words alone can do. For the purpose of increased lucidity we
will first show a plain multiple-series system.

Page 595
In this diagram G<1S> and G<2S> represent two generators, each
producing current at a potential of 110 volts. By connecting them in series
this potential is doubled, thus providing a main circuit (P and N) of 220
volts. The figures marked L represent eight lamps of 110 volts each, in
multiple series of two, in four derived circuits. The arrows indicate the flow
of current. By this method each pair of lamps takes, together, only the same
quantity or volume of current required by a single lamp in a simple
multiple-arc system; and, as the cross-section of a conductor depends upon
the quantity of current carried, such an arrangement as the above would
allow the use of conductors of only one-fourth the cross-section that would
be otherwise required. From the standpoint of economy of investment such
an arrangement would be highly desirable, but considered commercially it
is impracticable because the principle of independent control of each unit
would be lost, as the turning out of a lamp in any series would mean the
extinguishment of its companion also. By referring to the diagram it will be
seen that each series of two forms one continuous path between the main
conductors, and if this path be broken at any one point current will
immediately cease to flow in that particular series.
Edison, by his invention of the three-wire system, overcame this
difficulty entirely, and at the same time conserved approximately, the saving
of copper, as will be apparent from the following illustration of that system,
in its simplest form.
The reference figures are similar to those in the preceding diagram, and
all conditions are also alike except that a central compensating, or
balancing, conductor, PN, is here introduced. This is technically termed the
"neutral" wire, and in the discharge of its functions lies the solution of the
problem of economical distribution. Theoretically, a three-wire installation
is evenly balanced by wiring for an equal number of lamps on both sides. If
all these lamps were always lighted, burned, and extinguished
simultaneously the central conductor would, in fact, remain neutral, as there
would be no current passing through it, except from lamp to lamp. In
practice, however, no such perfect conditions can obtain, hence the
necessity of the provision for balancing in order to maintain the principle of
independent control of each unit.
It will be apparent that the arrangement shown in Fig. 2 comprises
practically two circuits combined in one system, in which the central
producing current at a potential of 110 volts. By connecting them in series
this potential is doubled, thus providing a main circuit (P and N) of 220
volts. The figures marked L represent eight lamps of 110 volts each, in
multiple series of two, in four derived circuits. The arrows indicate the flow

is evenly balanced by wiring for an equal number of lamps on both sides. If
all these lamps were always lighted, burned, and extinguished
simultaneously the central conductor would, in fact, remain neutral, as there
would be no current passing through it, except from lamp to lamp. In
practice, however, no such perfect conditions can obtain, hence the
necessity of the provision for balancing in order to maintain the principle of
independent control of each unit.
It will be apparent that the arrangement shown in Fig. 2 comprises
practically two circuits combined in one system, in which the central
Page 596
conductor, PN, in case of emergency, serves in two capacities—namely, as
negative to generator G<1S> or as positive to generator G<2S>, although
normally neutral. There are two sides to the system, the positive side being
represented by the conductors P and PN, and the negative side by the
conductors PN and N. Each side, if considered separately, has a potential of
about 110 volts, yet the potential of the two outside conductors, P and N, is
220 volts. The lamps are 110 volts.
In practical use the operation of the system is as follows: If all the lamps
were lighted the current would flow along P and through each pair of lamps
to N, and so back to the source of energy. In this case the balance is
preserved and the central wire remains neutral, as no return current flows
through it to the source of energy. But let us suppose that one lamp on the
positive side is extinguished. None of the other lamps is affected thereby,
but the system is immediately thrown out of balance, and on the positive
side there is an excess of current to this extent which flows along or through
the central conductor and returns to the generator, the central conductor thus
becoming the negative of that side of the system for the time being. If the
lamp extinguished had been one of those on the negative side of the system
results of a similar nature would obtain, except that the central conductor
would for the time being become the positive of that side, and the excess of
current would flow through the negative, N, back to the source of energy.
Thus it will be seen that a three-wire system, considered as a whole, is
elastic in that it may operate as one when in balance and as two when
unbalanced, but in either event giving independent control of each unit.
For simplicity of illustration a limited number of circuits, shown in Fig.
2, has been employed. In practice, however, where great numbers of lamps
are in use (as, for instance, in New York City, where about 7,000,000 lamps
are operated from various central stations), there is constantly occurring
more or less change in the balance of many circuits extending over
considerable distances, but of course there is a net result which is always on
one side of the system or the other for the time being, and this is met by
proper adjustment at the appropriate generator in the station.
In order to make the explanation complete, there is presented another
diagram showing a three-wire system unbalanced:
The reference figures are used as before, but in this case the vertical lines
represent branches taken from the main conductors into buildings or other
negative to generator G<1S> or as positive to generator G<2S>, although
normally neutral. There are two sides to the system, the positive side being
represented by the conductors P and PN, and the negative side by the
conductors PN and N. Each side, if considered separately, has a potential of
about 110 volts, yet the potential of the two outside conductors, P and N, is
220 volts. The lamps are 110 volts.
In practical use the operation of the system is as follows: If all the lamps
were lighted the current would flow along P and through each pair of lamps
to N, and so back to the source of energy. In this case the balance is
preserved and the central wire remains neutral, as no return current flows
through it to the source of energy. But let us suppose that one lamp on the
positive side is extinguished. None of the other lamps is affected thereby,
but the system is immediately thrown out of balance, and on the positive
side there is an excess of current to this extent which flows along or through
the central conductor and returns to the generator, the central conductor thus
becoming the negative of that side of the system for the time being. If the
lamp extinguished had been one of those on the negative side of the system
results of a similar nature would obtain, except that the central conductor
would for the time being become the positive of that side, and the excess of
current would flow through the negative, N, back to the source of energy.
Thus it will be seen that a three-wire system, considered as a whole, is
elastic in that it may operate as one when in balance and as two when
unbalanced, but in either event giving independent control of each unit.

The reference figures are used as before, but in this case the vertical lines
represent branches taken from the main conductors into buildings or other
Page 597
spaces to be lighted, and the loops between these branch wires represent
lamps in operation. It will be seen from this sketch that there are ten lamps
on the positive side and twelve on the negative side. Hence, the net result is
an excess of current equal to that required by two lamps flowing through
the central or compensating conductor, which is now acting as positive to
generator G<2S> The arrows show the assumed direction of flow of current
throughout the system, and the small figures at the arrow-heads the volume
of that current expressed in the number of lamps which it supplies.
The commercial value of this invention may be appreciated from the fact
that by the application of its principles there is effected a saving of 62 1/2
per cent. of the amount of copper over that which would be required for
conductors in any previously devised two-wire system carrying the same
load. This arises from the fact that by the doubling of potential the two
outside mains are reduced to one-quarter the cross-section otherwise
necessary. A saving of 75 per cent. would thus be assured, but the addition
of a third, or compensating, conductor of the same cross-section as one of
the outside mains reduces the total saving to 62 1/2 per cent.
The three-wire system is in universal use throughout the world at the
present day.

XIII. EDISON'S ELECTRIC RAILWAY
AS narrated in Chapter XVIII, there were two electric railroads installed
by Edison at Menlo Park—one in 1880, originally a third of a mile long, but
subsequently increased to about a mile in length, and the other in 1882,
about three miles long. As the 1880 road was built very soon after Edison's
notable improvements in dynamo machines, and as the art of operating
them to the best advantage was then being developed, this early road was
somewhat crude as compared with the railroad of 1882; but both were
practicable and serviceable for the purpose of hauling passengers and
freight. The scope of the present article will be confined to a description of
the technical details of these two installations.
The illustration opposite page 454 of the preceding narrative shows the
first Edison locomotive and train of 1880 at Menlo Park.
For the locomotive a four-wheel iron truck was used, and upon it was
mounted one of the long "Z" type 110-volt Edison dynamos, with a capacity
of 75 amperes, which was to be used as a motor. This machine was laid on
its side, its armature being horizontal and located toward the front of the
locomotive.
We now quote from an article by Mr. E. W. Hammer, published in the
Electrical World, New York, June 10, 1899, and afterward elaborated and
reprinted in a volume entitled Edisonia, compiled and published under the
auspices of a committee of the Association of Edison Illuminating
Companies, in 1904: "The gearing originally employed consisted of a
friction-pulley upon the armature shaft, another friction-pulley upon the
driven axle, and a third friction-pulley which could be brought in contact
with the other two by a suitable lever. Each wheel of the locomotive was
made with metallic rim and a centre portion made of wood or papier-mache.
A three-legged spider connected the metal rim of each front wheel to a brass
hub, upon which rested a collecting brush. The other wheels were
subsequently so equipped. It was the intention, therefore, that the current
should enter the locomotive wheels at one side, and after passing through
the metal spiders, collecting brushes and motor, would pass out through the
corresponding brushes, spiders, and wheels to the other rail."

As to the road: "The rails were light and were spiked to ordinary sleepers,
with a gauge of about three and one-half feet. The sleepers were laid upon
the natural grade, and there was comparatively no effort made to ballast the
road. . . . No special precautions were taken to insulate the rails from the
earth or from each other."
The road started about fifty feet away from the generating station, which
in this case was the machine shop. Two of the "Z" type dynamos were used
for generating the current, which was conveyed to the two rails of the road
by underground conductors.
On Thursday, May 13, 1880, at 4 o'clock in the afternoon, this historic
locomotive made its first trip, packed with as many of the "boys" as could
possibly find a place to hang on. "Everything worked to a charm, until, in
starting up at one end of the road, the friction gearing was brought into
action too suddenly and it was wrecked. This accident demonstrated that
some other method of connecting the armature with the driven axle should
be arranged.
"As thus originally operated, the motor had its field circuit in permanent
connection as a shunt across the rails, and this field circuit was protected by
a safety-catch made by turning up two bare ends of the wire in its circuit
and winding a piece of fine copper wire across from one bare end to the
other. The armature circuit had a switch in it which permitted the
locomotive to be reversed by reversing the direction of current flow through
the armature.
"After some consideration of the gearing question, it was decided to
employ belts instead of the friction-pulleys." Accordingly, Edison installed
on the locomotive a system of belting, including an idler-pulley which was
used by means of a lever to tighten the main driving-belt, and thus power
was applied to the driven axle. This involved some slipping and consequent
burning of belts; also, if the belt were prematurely tightened, the burning-
out of the armature. This latter event happened a number of times, "and
proved to be such a serious annoyance that resistance-boxes were brought
out from the laboratory and placed upon the locomotive in series with the
armature. This solved the difficulty. The locomotive would be started with
these resistance-boxes in circuit, and after reaching full speed the operator
could plug the various boxes out of circuit, and in that way increase the
with a gauge of about three and one-half feet. The sleepers were laid upon
the natural grade, and there was comparatively no effort made to ballast the
road. . . . No special precautions were taken to insulate the rails from the
earth or from each other."
The road started about fifty feet away from the generating station, which
in this case was the machine shop. Two of the "Z" type dynamos were used
for generating the current, which was conveyed to the two rails of the road
by underground conductors.

out of the armature. This latter event happened a number of times, "and
proved to be such a serious annoyance that resistance-boxes were brought
out from the laboratory and placed upon the locomotive in series with the
armature. This solved the difficulty. The locomotive would be started with
these resistance-boxes in circuit, and after reaching full speed the operator
could plug the various boxes out of circuit, and in that way increase the
Page 600
speed." To stop, the armature circuit was opened by the main switch and the
brake applied.
This arrangement was generally satisfactory, but the resistance-boxes
scattered about the platform and foot-rests being in the way, Edison directed
that some No. 8 B. & S. copper wire be wound on the lower leg of the
motor field-magnet. "By doing this the resistance was put where it would
take up the least room, and where it would serve as an additional field-coil
when starting the motor, and it replaced all the resistance-boxes which had
heretofore been in plain sight. The boxes under the seat were still retained
in service. The coil of coarse wire was in series with the armature, just as
the resistance-boxes had been, and could be plugged in or out of circuit at
the will of the locomotive driver. The general arrangement thus secured was
operated as long as this road was in commission."
On this short stretch of road there were many sharp curves and steep
grades, and in consequence of the high speed attained (as high as forty-two
miles an hour) several derailments took place, but fortunately without
serious results. Three cars were in service during the entire time of
operating this 1880 railroad: one a flat-car for freight; one an open car with
two benches placed back to back; and the third a box-car, familiarly known
as the "Pullman." This latter car had an interesting adjunct in an electric
braking system (covered by Edison's Patent No. 248,430). "Each car axle
had a large iron disk mounted on and revolving with it between the poles of
a powerful horseshoe electromagnet. The pole-pieces of the magnet were
movable, and would be attracted to the revolving disk when the magnet was
energized, grasping the same and acting to retard the revolution of the car
axle."
Interesting articles on Edison's first electric railroad were published in the
technical and other papers, among which may be mentioned the New York
Herald, May 15 and July 23, 1880; the New York Graphic, July 27, 1880;
and the Scientific American, June 6, 1880.
Edison's second electric railroad of 1882 was more pretentious as regards
length, construction, and equipment. It was about three miles long, of nearly
standard gauge, and substantially constructed. Curves were modified, and
grades eliminated where possible by the erection of numerous trestles. This
road also had some features of conventional railroads, such as sidings, turn-
tables, freight platform, and car-house. "Current was supplied to the road by
brake applied.

Page 601
underground feeder cables from the dynamo-room of the laboratory. The
rails were insulated from the ties by giving them two coats of japan, baking
them in the oven, and then placing them on pads of tar-impregnated muslin
laid on the ties. The ends of the rails were not japanned, but were
electroplated, to give good contact surfaces for fish-plates and copper
bonds."
The following notes of Mr. Frederick A. Scheffler, who designed the
passenger locomotive for the 1882 road, throw an interesting light on its
technical details:
"In May, 1881, I was engaged by Mr. M. F. Moore, who was the first
General Manager of the Edison Company for Isolated Lighting, as a
draftsman to undertake the work of designing and building Edison's electric
locomotive No. 2.
"Previous to that time I had been employed in the engineering
department of Grant Locomotive Works, Paterson, New Jersey, and the
Rhode Island Locomotive Works, Providence, Rhode Island....
"It was Mr. Edison's idea, as I understood it at that time, to build a
locomotive along the general lines of steam locomotives (at least, in
outward appearance), and to combine in that respect the framework, truck,
and other parts known to be satisfactory in steam locomotives at the same
time.
"This naturally required the services of a draftsman accustomed to steam-
locomotive practice.... Mr. Moore was a man of great railroad and
locomotive experience, and his knowledge in that direction was of great
assistance in the designing and building of this locomotive.
"At that time I had no knowledge of electricity.... One could count so-
called electrical engineers on his fingers then, and have some fingers left
over.
"Consequently, the ELECTRICAL equipment was designed by Mr.
Edison and his assistants. The data and parts, such as motor, rheostat,
switches, etc., were given to me, and my work was to design the supporting
frame, axles, countershafts, driving mechanism, speed control, wheels and
boxes, cab, running board, pilot (or 'cow-catcher'), buffers, and even
supports for the headlight. I believe I also designed a bell and supports.
From this it will be seen that the locomotive had all the essential
paraphernalia to make it LOOK like a steam locomotive.
rails were insulated from the ties by giving them two coats of japan, baking
them in the oven, and then placing them on pads of tar-impregnated muslin
laid on the ties. The ends of the rails were not japanned, but were
electroplated, to give good contact surfaces for fish-plates and copper
bonds."
The following notes of Mr. Frederick A. Scheffler, who designed the
passenger locomotive for the 1882 road, throw an interesting light on its
technical details:
"In May, 1881, I was engaged by Mr. M. F. Moore, who was the first
General Manager of the Edison Company for Isolated Lighting, as a
draftsman to undertake the work of designing and building Edison's electric
locomotive No. 2.
"Previous to that time I had been employed in the engineering
department of Grant Locomotive Works, Paterson, New Jersey, and the
Rhode Island Locomotive Works, Providence, Rhode Island....
"It was Mr. Edison's idea, as I understood it at that time, to build a
locomotive along the general lines of steam locomotives (at least, in
outward appearance), and to combine in that respect the framework, truck,
and other parts known to be satisfactory in steam locomotives at the same
time.
"This naturally required the services of a draftsman accustomed to steam-
locomotive practice.... Mr. Moore was a man of great railroad and
locomotive experience, and his knowledge in that direction was of great
assistance in the designing and building of this locomotive.
"At that time I had no knowledge of electricity.... One could count so-
called electrical engineers on his fingers then, and have some fingers left
over.
"Consequently, the ELECTRICAL equipment was designed by Mr.
Edison and his assistants. The data and parts, such as motor, rheostat,
switches, etc., were given to me, and my work was to design the supporting
frame, axles, countershafts, driving mechanism, speed control, wheels and
boxes, cab, running board, pilot (or 'cow-catcher'), buffers, and even
supports for the headlight. I believe I also designed a bell and supports.
From this it will be seen that the locomotive had all the essential
paraphernalia to make it LOOK like a steam locomotive.

"The principal part of the outfit was the electric motor. At that time
motors were curiosities. There were no electric motors even for stationary
purposes, except freaks built for experimental uses. This motor was made
from the parts—such as fields, armature, commutator, shaft and bearings,
etc., of an Edison 'Z,' or 60-light dynamo. It was the only size of dynamo
that the Edison Company had marketed at that time.... As a motor, it was
wound to run at maximum speed to develop a torque equal to about fifteen
horse-power with 220 volts. At the generating station at Menlo Park four Z
dynamos of 110 volts were used, connected two in series, in multiple arc,
giving a line voltage of 220.
"The motor was located in the front part of the locomotive, on its side,
with the armature shaft across the frames, or parallel with the driving axles.
"On account of the high speed of the armature shaft it was not possible to
connect with driving-axles direct, but this was an advantage in one way, as
by introducing an intermediate counter-shaft (corresponding to the well-
known type of double-reduction motor used on trolley-cars since 1885), a
fairly good arrangement was obtained to regulate the speed of the
locomotive, exclusive of resistance in the electric circuit.
"Endless leather belting was used to transmit the power from the motor to
the counter-shaft, and from the latter to the driving-wheels, which were the
front pair. A vertical idler-pulley was mounted in a frame over the belt from
motor to counter-shaft, terminating in a vertical screw and hand-wheel for
tightening the belt to increase speed, or the reverse to lower speed. This
hand-wheel was located in the cab, where it was easily accessible....
"The rough outline sketched below shows the location of motor in
relation to counter-shaft, belting, driving-wheels, idler, etc.:
"On account of both rails being used for circuits, . . . the driving-wheels
had to be split circumferentially and completely insulated from the axles.
This was accomplished by means of heavy wood blocks well shellacked or
otherwise treated to make them water and weather proof, placed radially on
the inside of the wheels, and then substantially bolted to the hubs and rims
of the latter.
"The weight of the locomotive was distributed over the driving-wheels in
the usual locomotive practice by means of springs and equalizers.
"The current was taken from the rims of the driving-wheels by a three-
pronged collector of brass, against which flexible copper brushes were

"The late Mr. Charles T. Hughes was in charge of the track construction
at Menlo Park.... His work was excellent throughout, and the results were
highly satisfactory so far as they could possibly be with the arrangement
originally planned by Mr. Edison and his assistants.
"Mr. Charles L. Clarke, one of the earliest electrical engineers employed
by Mr. Edison, made a number of tests on this 1882 railroad. I believe that
the engine driving the four Z generators at the power-house indicated as
high as seventy horse-power at the time the locomotive was actually in
service."
The electrical features of the 1882 locomotive were very similar to those
of the earlier one, already described. Shunt and series field-windings were
added to the motor, and the series windings could be plugged in and out of
circuit as desired. The series winding was supplemented by resistance-
boxes, also capable of being plugged in or out of circuit. These various
electrical features are diagrammatically shown in Fig. 2, which also
illustrates the connection with the generating plant.
We quote again from Mr. Hammer, who says: "The freight-locomotive
had single reduction gears, as is the modern practice, but the power was
applied through a friction-clutch The passenger-locomotive was very
speedy, and ninety passengers have been carried at a time by it; the freight-
locomotive was not so fast, but could pull heavy trains at a good speed.
Many thousand people were carried on this road during 1882." The general
appearance of Edison's electric locomotive of 1882 is shown in the
illustration opposite page 462 of the preceding narrative. In the picture Mr.
Edison may be seen in the cab, and Mr. Insull on the front platform of the
passenger-car.

XIV. TRAIN TELEGRAPHY
WHILE the one-time art of telegraphing to and from moving trains was
essentially a wireless system, and allied in some of its principles to the art
of modern wireless telegraphy through space, the two systems cannot,
strictly speaking be regarded as identical, as the practice of the former was
based entirely on the phenomenon of induction.
Briefly described in outline, the train telegraph system consisted of an
induction circuit obtained by laying strips of metal along the top or roof of a
railway-car, and the installation of a special telegraph line running parallel
with the track and strung on poles of only medium height. The train, and
also each signalling station, was equipped with regulation telegraph
apparatus, such as battery, key, relay, and sounder, together with induction-
coil and condenser. In addition, there was a special transmitting device in
the shape of a musical reed, or "buzzer." In practice, this buzzer was
continuously operated at a speed of about five hundred vibrations per
second by an auxiliary battery. Its vibrations were broken by means of a
telegraph key into long and short periods, representing Morse characters,
which were transmitted inductively from the train circuit to the pole line or
vice versa, and received by the operator at the other end through a high-
resistance telephone receiver inserted in the secondary circuit of the
induction-coil.
The accompanying diagrammatic sketch of a simple form of the system,
as installed on a car, will probably serve to make this more clear.
An insulated wire runs from the metallic layers on the roof of the car to
switch S, which is shown open in the sketch. When a message is to be
received on the car from a station more or less remote, the switch is thrown
to the left to connect with a wire running to the telephone receiver, T. The
other wire from this receiver is run down to one of the axles and there
permanently connected, thus making a ground. The operator puts the
receiver to his ear and listens for the message, which the telephone renders
audible in the Morse characters.

receiver to his ear and listens for the message, which the telephone renders
audible in the Morse characters.
Page 605
If a message is to be transmitted from the car to a receiving station, near
or distant, the switch, S, is thrown to the other side, thus connecting with a
wire leading to one end of the secondary of induction-coil C. The other end
of the secondary is connected with the grounding wire. The primary of the
induction-coil is connected as shown, one end going to key K and the other
to the buzzer circuit. The other side of the key is connected to the
transmitting battery, while the opposite pole of this battery is connected in
the buzzer circuit. The buzzer, R, is maintained in rapid vibration by its
independent auxiliary battery, B<1S>.
When the key is pressed down the circuit is closed, and current from the
transmitting battery, B, passes through primary of the coil, C, and induces a
current of greatly increased potential in the secondary. The current as it
passes into the primary, being broken up into short impulses by the
tremendously rapid vibrations of the buzzer, induces similarly rapid waves
of high potential in the secondary, and these in turn pass to the roof and
thence through the intervening air by induction to the telegraph wire. By a
continued lifting and depression of the key in the regular manner, these
waves are broken up into long and short periods, and are thus transmitted to
the station, via the wire, in Morse characters, dots and dashes.
The receiving stations along the line of the railway were similarly
equipped as to apparatus, and, generally speaking the operations of sending
and receiving messages were substantially the same as above described.
The equipment of an operator on a car was quite simple consisting
merely of a small lap-board, on which were mounted the key, coil, and
buzzer, leaving room for telegraph blanks. To this board were also attached
flexible conductors having spring clips, by means of which connections
could be made quickly with conveniently placed terminals of the ground,
roof, and battery wires. The telephone receiver was held on the head with a
spring, the flexible connecting wire being attached to the lap board, thus
leaving the operator with both hands free.
The system, as shown in the sketch and elucidated by the text, represents
the operation of train telegraphy in a simple form, but combining the main
essentials of the art as it was successfully and commercially practiced for a
number of years after Edison and Gilliland entered the field. They
elaborated the system in various ways, making it more complete; but it has

XV. KINETOGRAPH AND PROJECTING
KINETOSCOPE
ALTHOUGH many of the arts in which Edison has been a pioneer have
been enriched by his numerous inventions and patents, which were
subsequent to those of a fundamental nature, the (so-called) motion-picture
art is an exception, as the following, together with three other additional
patents [30] comprise all that he has taken out on this subject: United States
Patent No. 589,168, issued August 31, 1897, reissued in two parts—namely,
No. 12,037, under date of September 30,1902, and No. 12,192, under date
of January 12, 1904. Application filed August 24, 1891.
[Footnote 30: Not 491,993, issued February 21, 1893; No.
493,426, issued March 14, 1893; No. 772,647, issued October
18, 1904.]
There is nothing surprising in this, however, as the possibility of
photographing and reproducing actual scenes of animate life are so
thoroughly exemplified and rendered practicable by the apparatus and
methods disclosed in the patents above cited, that these basic inventions in
themselves practically constitute the art—its development proceeding
mainly along the line of manufacturing details. That such a view of his
work is correct, the highest criterion—commercial expediency—bears
witness; for in spite of the fact that the courts have somewhat narrowed the
broad claims of Edison's patents by reason of the investigations of earlier
experimenters, practically all the immense amount of commercial work that
is done in the motion-picture field to-day is accomplished through the use
of apparatus and methods licensed under the Edison patents.
The philosophy of this invention having already been described in
Chapter XXI, it will be unnecessary to repeat it here. Suffice it to say by
way of reminder that it is founded upon the physiological phenomenon
known as the persistence of vision, through which a series of sequential
photographic pictures of animate motion projected upon a screen in rapid
succession will reproduce to the eye all the appearance of the original
movements.

Page 608
Edison's work in this direction comprised the invention not only of a
special form of camera for making original photographic exposures from a
single point of view with very great rapidity, and of a machine adapted to
effect the reproduction of such pictures in somewhat similar manner but
also of the conception and invention of a continuous uniform, and evenly
spaced tape-like film, so absolutely essential for both the above objects.
The mechanism of such a camera, as now used, consists of many parts
assembled in such contiguous proximity to each other that an illustration
from an actual machine would not help to clearness of explanation to the
general reader. Hence a diagram showing a sectional view of a simple form
of such a camera is presented below.
In this diagram, A represents an outer light-tight box containing a lens, C,
and the other necessary mechanism for making the photographic exposures,
H<1S> and H<2S> being cases for holding reels of film before and after
exposure, F the long, tape-like film, G a sprocket whose teeth engage in
perforations on the edges of the film, such sprocket being adapted to be
revolved with an intermittent or step-by-step movement by hand or by
motor, and B a revolving shutter having an opening and connected by gears
with G, and arranged to expose the film during the periods of rest. A full
view of this shutter is also represented, with its opening, D, in the small
illustration to the right.
In practice, the operation would be somewhat as follows, generally
speaking: The lens would first be focussed on the animate scene to be
photographed. On turning the main shaft of the camera the sprocket, G, is
moved intermittently, and its teeth, catching in the holes in the sensitized
film, draws it downward, bringing a new portion of its length in front of the
lens, the film then remaining stationary for an instant. In the mean time,
through gearing connecting the main shaft with the shutter, the latter is
rotated, bringing its opening, D, coincident with the lens, and therefore
exposing the film while it is stationary, after which the film again moves
forward. So long as the action is continued these movements are repeated,
resulting in a succession of enormously rapid exposures upon the film
during its progress from reel H<1S> to its automatic rewinding on reel
H<2S>. While the film is passing through the various parts of the machine
it is guided and kept straight by various sets of rollers between which it
runs, as indicated in the diagram.

Page 609
By an ingenious arrangement of the mechanism, the film moves
intermittently so that it may have a much longer period of rest than of
motion. As in practice the pictures are taken at a rate of twenty or more per
second, it will be quite obvious that each period of rest is infinitesimally
brief, being generally one-thirtieth of a second or less. Still it is sufficient to
bring the film to a momentary condition of complete rest, and to allow for a
maximum time of exposure, comparatively speaking, thus providing means
for taking clearly defined pictures. The negatives so obtained are developed
in the regular way, and the positive prints subsequently made from them are
used for reproduction.
The reproducing machine, or, as it is called in practice, the Projecting
Kinetoscope, is quite similar so far as its general operations in handling the
film are concerned. In appearance it is somewhat different; indeed, it is in
two parts, the one containing the lighting arrangements and condensing
lens, and the other embracing the mechanism and objective lens. The
"taking" camera must have its parts enclosed in a light-tight box, because of
the undeveloped, sensitized film, but the projecting kinetoscope, using only
a fully developed positive film, may, and, for purposes of convenient
operation, must be accessibly open. The illustration (Fig. 2) will show the
projecting apparatus as used in practice.
The philosophy of reproduction is very simple, and is illustrated
diagrammatically in Fig. 3, reference letters being the same as in Fig. 1. As
to the additional reference letters, I is a condenser J the source of light, and
K a reflector.
The positive film is moved intermittently but swiftly throughout its
length between the objective lens and a beam of light coming through the
condenser, being exposed by the shutter during the periods of rest. This
results in a projection of the photographs upon a screen in such rapid
succession as to present an apparently continuous photograph of the
successive positions of the moving objects, which, therefore, appear to the
human eye to be in motion.
The first claim of Reissue Patent No. 12,192 describes the film. It reads
as follows:
"An unbroken transparent or translucent tape-like photographic film
having thereon uniform, sharply defined, equidistant photographs of
successive positions of an object in motion as observed from a single point
intermittently so that it may have a much longer period of rest than of
motion. As in practice the pictures are taken at a rate of twenty or more per
second, it will be quite obvious that each period of rest is infinitesimally
brief, being generally one-thirtieth of a second or less. Still it is sufficient to
bring the film to a momentary condition of complete rest, and to allow for a

XVI. EDISON'S ORE-MILLING INVENTIONS
THE wide range of Edison's activities in this department of the arts is
well represented in the diversity of the numerous patents that have been
issued to him from time to time. These patents are between fifty and sixty in
number, and include magnetic ore separators of ten distinct types; also
breaking, crushing, and grinding rolls, conveyors, dust-proof bearings,
screens, driers, mixers, bricking apparatus and machines, ovens, and
processes of various kinds.
A description of the many devices in each of these divisions would
require more space than is available; hence, we shall confine ourselves to a
few items of predominating importance, already referred to in the narrative,
commencing with the fundamental magnetic ore separator, which was
covered by United States Patent No. 228,329, issued June 1, 1880.
The illustration here presented is copied from the drawing forming part
of this patent. A hopper with adjustable feed is supported several feet above
a bin having a central partition. Almost midway between the hopper and the
bin is placed an electromagnet whose polar extension is so arranged as to be
a little to one side of a stream of material falling from the hopper. Normally,
a stream of finely divided ore falling from the hopper would fall into that
portion of the bin lying to the left of the partition. If, however, the magnet is
energized from a source of current, the magnetic particles in the falling
stream are attracted by and move toward the magnet, which is so placed
with relation to the falling material that the magnetic particles cannot be
attracted entirely to the magnet before gravity has carried them past. Hence,
their trajectory is altered, and they fall on the right-hand side of the partition
in the bin, while the non-magnetic portion of the stream continues in a
straight line and falls on the other side, thus effecting a complete separation.
This simple but effective principle was the one employed by Edison in
his great concentrating plant already described. In practice, the numerous
hoppers, magnets, and bins were many feet in length; and they were
arranged in batteries of varied magnetic strength, in order that the
intermingled mass of crushed rock and iron ore might be more thoroughly
separated by being passed through magnetic fields of successively

straight line and falls on the other side, thus effecting a complete separation.
This simple but effective principle was the one employed by Edison in
his great concentrating plant already described. In practice, the numerous
hoppers, magnets, and bins were many feet in length; and they were
arranged in batteries of varied magnetic strength, in order that the
intermingled mass of crushed rock and iron ore might be more thoroughly
separated by being passed through magnetic fields of successively
Page 612
increasing degrees of attracting power. Altogether there were about four
hundred and eighty of these immense magnets in the plant, distributed in
various buildings in batteries as above mentioned, the crushed rock
containing the iron ore being delivered to them by conveyors, and the
gangue and ore being taken away after separation by two other conveyors
and delivered elsewhere. The magnetic separators at first used by Edison at
this plant were of the same generality as the ones employed some years
previously in the separation of sea-shore sand, but greatly enlarged and
improved. The varied experiences gained in the concentration of vast
quantities of ore led naturally to a greater development, and several new
types and arrangements of magnetic separators were evolved and elaborated
by him from first to last, during the progress of the work at the
concentrating plant.
The magnetic separation of iron from its ore being the foundation idea of
the inventions now under discussion, a consideration of the separator has
naturally taken precedence over those of collateral but inseparable interest.
The ore-bearing rock, however, must first be ground to powder before it can
be separated; hence, we will now begin at the root of this operation and
consider the "giant rolls," which Edison devised for breaking huge masses
of rock. In his application for United States Patent No. 672,616, issued
April 23, 1901, applied for on July 16, 1897, he says: "The object of my
invention is to produce a method for the breaking of rock which will be
simple and effective, will not require the hand-sledging or blasting of the
rock down to pieces of moderate size, and will involve the consumption of
a small amount of power."
While this quotation refers to the method as "simple," the patent under
consideration covers one of the most bold and daring projects that Edison
has ever evolved. He proposed to eliminate the slow and expensive method
of breaking large boulders manually, and to substitute therefor momentum
and kinetic energy applied through the medium of massive machinery,
which, in a few seconds, would break into small pieces a rock as big as an
ordinary upright cottage piano, and weighing as much as six tons. Engineers
to whom Edison communicated his ideas were unanimous in declaring the
thing an impossibility; it was like driving two express-trains into each other
at full speed to crack a great rock placed between them; that no practical
machinery could be built to stand the terrific impact and strains. Edison's
convictions were strong, however, and he persisted. The experiments were

convictions were strong, however, and he persisted. The experiments were
Page 613
of heroic size, physically and financially, but after a struggle of several
years and an expenditure of about $100,000, he realized the correctness and
practicability of his plans in the success of the giant rolls, which were the
outcome of his labors.
The giant rolls consist of a pair of iron cylinders of massive size and
weight, with removable wearing plates having irregular surfaces formed by
projecting knobs. These rolls are mounted side by side in a very heavy
frame (leaving a gap of about fourteen inches between them), and are so
belted up with the source of power that they run in opposite directions. The
giant rolls described by Edison in the above-named patent as having been
built and operated by him had a combined weight of 167,000 pounds,
including all moving parts, which of themselves weighed about seventy
tons, each roll being six feet in diameter and five feet long. A top view of
the rolls is shown in the sketch, one roll and one of its bearings being
shown in section.
In Fig. 2 the rolls are illustrated diagrammatically. As a sketch of this
nature, even if given with a definite scale, does not always carry an
adequate idea of relative dimensions to a non-technical reader, we present
in Fig. 3 a perspective illustration of the giant rolls as installed in the
concentrating plant.
In practice, a small amount of power is applied to run the giant rolls
gradually up to a surface speed of several thousand feet a minute. When this
high speed is attained, masses of rock weighing several tons in one or more
pieces are dumped into a hopper which guides them into the gap between
the rapidly revolving rolls. The effect is to partially arrest the swift motion
of the rolls instantaneously, and thereby develop and expend an enormous
amount of kinetic energy, which with pile-driver effect cracks the rocks and
breaks them into pieces small enough to pass through the fourteen-inch gap.
As the power is applied to the rolls through slipping friction-clutches, the
speed of the driving-pulleys is not materially reduced; hence the rolls may
again be quickly speeded up to their highest velocity while another load of
rock is being hoisted in position to be dumped into the hopper. It will be
obvious from the foregoing that if it were attempted to supply the great
energy necessary for this operation by direct application of steam-power, an
engine of enormous horse-power would be required, and even then it is
doubtful if one could be constructed of sufficient strength to withstand the
years and an expenditure of about $100,000, he realized the correctness and

terrific strains that would ensue. But the work is done by the great
momentum and kinetic energy obtained by speeding up these tremendous
masses of metal, and then suddenly opposing their progress, the engine
being relieved of all strain through the medium of the slipping friction-
clutches. Thus, this cyclopean operation may be continuously conducted
with an amount of power prodigiously inferior, in proportion, to the results
accomplished.
The sketch (Fig. 4) showing a large boulder being dumped into the
hopper, or roll-pit, will serve to illustrate the method of feeding these great
masses of rock to the rolls, and will also enable the reader to form an idea
of the rapidity of the breaking operation, when it is stated that a boulder of
the size represented would be reduced by the giant rolls to pieces a trifle
larger than a man's head in a few seconds.
After leaving the giant rolls the broken rock passed on through other
crushing-rolls of somewhat similar construction. These also were invented
by Edison, but antedated those previously described; being covered by
Patent No. 567,187, issued September 8, 1896. These rolls were intended
for the reducing of "one-man-size" rocks to small pieces, which at the time
of their original inception was about the standard size of similar machines.
At the Edison concentrating plant the broken rock, after passing through
these rolls, was further reduced in size by other rolls, and was then ready to
be crushed to a fine powder through the medium of another remarkable
machine devised by Edison to meet his ever-recurring and well-defined
ideas of the utmost economy and efficiency.

and 85 of McClure's Magazine for November, 1897, by permission of S. S.

The best fine grinding-machines that it was then possible to obtain were
so inefficient as to involve a loss of 82 per cent. of the power applied. The
thought of such an enormous loss was unbearable, and he did not rest until
he had invented and put into use an entirely new grinding-machine, which
was called the "three-high" rolls. The device was covered by a patent issued
to him on November 21, 1899, No. 637,327. It was a most noteworthy
invention, for it brought into the art not only a greater efficiency of grinding
than had ever been dreamed of before, but also a tremendous economy by
the saving of power; for whereas the previous efficiency had been 18 per
momentum and kinetic energy obtained by speeding up these tremendous
masses of metal, and then suddenly opposing their progress, the engine
being relieved of all strain through the medium of the slipping friction-
clutches. Thus, this cyclopean operation may be continuously conducted

than had ever been dreamed of before, but also a tremendous economy by
the saving of power; for whereas the previous efficiency had been 18 per
Page 615
cent. and the loss 82 per cent., Edison reversed these figures, and in his
three-high rolls produced a working efficiency of 84 per cent., thus
reducing the loss of power by friction to 16 per cent. A diagrammatic sketch
of this remarkable machine is shown in Fig. 5, which shows a front
elevation with the casings, hopper, etc., removed, and also shows above the
rolls the rope and pulleys, the supports for which are also removed for the
sake of clearness in the illustration.
For the convenience of the reader, in referring to Fig. 5, we will repeat
the description of the three-high rolls, which is given on pages 487 and 488
of the preceding narrative.
In the two end-pieces of a heavy iron frame were set three rolls, or
cylinders—one in the centre, another below, and the other above—all three
being in a vertical line. These rolls were about three feet in diameter, made
of cast-iron, and had face-plates of chilled-iron. [31] The lowest roll was set
in a fixed bearing at the bottom of the frame, and, therefore, could only turn
around on its axis. The middle and top rolls were free to move up or down
from and toward the lower roll, and the shafts of the middle and upper rolls
were set in a loose bearing which could slip up and down in the iron frame.
It will be apparent, therefore, that any material which passed in between the
top and the middle rolls, and the middle and bottom rolls, could be ground
as fine as might be desired, depending entirely upon the amount of pressure
applied to the loose rolls. In operation the material passed first through the
upper and middle rolls, and then between the middle and lowest rolls.
[Footnote 31: The faces of these rolls were smooth, but as
three-high rolls came into use later in Edison's Portland
cement operations the faces were corrugated so as to fit
into each other, gear-fashion, to provide for a high rate of
feed]
This pressure was applied in a most ingenious manner. On the ends of the
shafts of the bottom and top rolls there were cylindrical sleeves, or
bearings, having seven sheaves in which was run a half-inch endless wire
rope. This rope was wound seven times over the sheaves as above, and led
upward and over a single-groove sheave, which was operated by the piston
of an air-cylinder, and in this manner the pressure was applied to the rolls. It
will be seen, therefore that the system consisted in a single rope passed over
sheaves and so arranged that it could be varied in length, thus providing for
elasticity in exerting pressure and regulating it as desired. The efficiency of
three-high rolls produced a working efficiency of 84 per cent., thus
reducing the loss of power by friction to 16 per cent. A diagrammatic sketch
of this remarkable machine is shown in Fig. 5, which shows a front
elevation with the casings, hopper, etc., removed, and also shows above the
rolls the rope and pulleys, the supports for which are also removed for the
sake of clearness in the illustration.

Page 616
this system was incomparably greater than that of any other known crusher
or grinder, for while a pressure of one hundred and twenty-five thousand
pounds could be exerted by these rolls, friction was almost entirely
eliminated, because the upper and lower roll bearings turned with the rolls
and revolved in the wire rope, which constituted the bearing proper.
Several other important patents have been issued to Edison for crushing
and grinding rolls, some of them being for elaborations and improvements
of those above described but all covering methods of greater economy and
effectiveness in rock-grinding.
Edison's work on conveyors during the period of his ore-concentrating
labors was distinctively original, ingenious and far in advance of the times.
His conception of the concentrating problem was broad and embraced an
entire system, of which a principal item was the continuous transfer of
enormous quantities of material from place to place at the lowest possible
cost. As he contemplated the concentration of six thousand tons daily, the
expense of manual labor to move such an immense quantity of rock, sand,
and ore would be absolutely prohibitive. Hence, it became necessary to
invent a system of conveyors that would be capable of transferring this
mass of material from one place to another. And not only must these
conveyors be capable of carrying the material, but they must also be
devised so that they would automatically receive and discharge their
respective loads at appointed places. Edison's ingenuity, engineering ability,
and inventive skill were equal to the task, however, and were displayed in a
system and variety of conveyors that in practice seemed to act with almost
human discrimination. When fully installed throughout the plant, they
automatically transferred daily a mass of material equal to about one
hundred thousand cubic feet, from mill to mill, covering about a mile in the
transit. Up and down, winding in and out, turning corners, delivering
material from one to another, making a number of loops in the drying-oven,
filling up bins and passing on to the next when they were full, these
conveyors in automatic action seemingly played their part with human
intelligence, which was in reality the reflection of the intelligence and
ingenuity that had originally devised them and set them in motion.
Six of Edison's patents on conveyors include a variety of devices that
have since came into broad general use for similar work, and have been the
means of effecting great economies in numerous industries of widely
or grinder, for while a pressure of one hundred and twenty-five thousand
pounds could be exerted by these rolls, friction was almost entirely
eliminated, because the upper and lower roll bearings turned with the rolls
and revolved in the wire rope, which constituted the bearing proper.

varying kinds. Interesting as they are, however, we shall not attempt to
describe them in detail, as the space required would be too great. They are
specified in the list of patents following this Appendix, and may be
examined in detail by any interested student.
In the same list will also be found a large number of Edison's patents on
apparatus and methods of screening, drying, mixing, and briquetting, as
well as for dust-proof bearings, and various types and groupings of
separators, all of which were called forth by the exigencies and magnitude
of his great undertaking, and without which he could not possibly have
attained the successful physical results that crowned his labors. Edison's
persistence in reducing the cost of his operations is noteworthy in
connection with his screening and drying inventions, in which the utmost
advantage is taken of the law of gravitation. With its assistance, which cost
nothing, these operations were performed perfectly. It was only necessary to
deliver the material at the top of the chambers, and during its natural
descent it was screened or dried as the case might be.
All these inventions and devices, as well as those described in detail

industry presents many of the identical problems which presented
themselves in relation to the concentration of iron ore.

XVII. THE LONG CEMENT KILN
IN this remarkable invention, which has brought about a striking
innovation in a long-established business, we see another characteristic
instance of Edison's incisive reasoning and boldness of conception carried
into practical effect in face of universal opinions to the contrary.
For the information of those unacquainted with the process of
manufacturing Portland cement, it may be stated that the material consists
preliminarily of an intimate mixture of cement rock and limestone, ground
to a very fine powder. This powder is technically known in the trade as
"chalk," and is fed into rotary kilns and "burned"; that is to say, it is
subjected to a high degree of heat obtained by the combustion of pulverized
coal, which is injected into the interior of the kiln. This combustion effects
a chemical decomposition of the chalk, and causes it to assume a plastic
consistency and to collect together in the form of small spherical balls,
which are known as "clinker." Kilns are usually arranged with a slight
incline, at the upper end of which the chalk is fed in and gradually works its
way down to the interior flame of burning fuel at the other end. When it
arrives at the lower end, the material has been "burned," and the clinker
drops out into a receiving chamber below. The operation is continuous, a
constant supply of chalk passing in at one end of the kiln and a continuous
dribble of clinker-balls dropping out at the other. After cooling, the clinker
is ground into very fine powder, which is the Portland cement of commerce.
It is self-evident that an ideal kiln would be one that produced the
maximum quantity of thoroughly clinkered material with a minimum
amount of fuel, labor, and investment. When Edison was preparing to go
into the cement business, he looked the ground over thoroughly, and, after
considerable investigation and experiment, came to the conclusion that
prevailing conditions as to kilns were far from ideal.
The standard kilns then in use were about sixty feet in length, with an
internal diameter of about five feet. In all rotary kilns for burning cement,
the true clinkering operation takes place only within a limited portion of
their total length, where the heat is greatest; hence the interior of the kiln
may be considered as being divided longitudinally into two parts or zones—
IN this remarkable invention, which has brought about a striking
innovation in a long-established business, we see another characteristic
instance of Edison's incisive reasoning and boldness of conception carried
into practical effect in face of universal opinions to the contrary.
For the information of those unacquainted with the process of
manufacturing Portland cement, it may be stated that the material consists
preliminarily of an intimate mixture of cement rock and limestone, ground
to a very fine powder. This powder is technically known in the trade as
"chalk," and is fed into rotary kilns and "burned"; that is to say, it is
subjected to a high degree of heat obtained by the combustion of pulverized
coal, which is injected into the interior of the kiln. This combustion effects
a chemical decomposition of the chalk, and causes it to assume a plastic
consistency and to collect together in the form of small spherical balls,
which are known as "clinker." Kilns are usually arranged with a slight
incline, at the upper end of which the chalk is fed in and gradually works its
way down to the interior flame of burning fuel at the other end. When it
arrives at the lower end, the material has been "burned," and the clinker
drops out into a receiving chamber below. The operation is continuous, a
constant supply of chalk passing in at one end of the kiln and a continuous
dribble of clinker-balls dropping out at the other. After cooling, the clinker
is ground into very fine powder, which is the Portland cement of commerce.
It is self-evident that an ideal kiln would be one that produced the
maximum quantity of thoroughly clinkered material with a minimum
amount of fuel, labor, and investment. When Edison was preparing to go
into the cement business, he looked the ground over thoroughly, and, after
considerable investigation and experiment, came to the conclusion that
prevailing conditions as to kilns were far from ideal.
The standard kilns then in use were about sixty feet in length, with an
internal diameter of about five feet. In all rotary kilns for burning cement,
the true clinkering operation takes place only within a limited portion of
their total length, where the heat is greatest; hence the interior of the kiln
may be considered as being divided longitudinally into two parts or zones—
Page 619
namely, the combustion, or clinkering, zone, and the zone of oncoming raw
material. In the sixty-foot kiln the length of the combustion zone was about
ten feet, extending from a point six or eight feet from the lower, or
discharge, end to a point about eighteen feet from that end. Consequently,
beyond that point there was a zone of only about forty feet, through which
the heated gases passed and came in contact with the oncoming material,
which was in movement down toward the clinkering zone. Since the bulk of
oncoming material was small, the gases were not called upon to part with
much of their heat, and therefore passed on up the stack at very high
temperatures, ranging from 1500 degrees to 1800 degrees Fahr. Obviously,
this heat was entirely lost.
An additional loss of efficiency arose from the fact that the material
moved so rapidly toward the combustion zone that it had not given up all its
carbon dioxide on reaching there; and by the giving off of large quantities
of that gas within the combustion zone, perfect and economical combustion
of coal could not be effected.
The comparatively short length of the sixty-foot kiln not only limited the
amount of material that could be fed into it, but the limitation in length of
the combustion zone militated against a thorough clinkering of the material,
this operation being one in which the elements of time and proper heat are
prime considerations. Thus the quantity of good clinker obtainable was
unfavorably affected. By reason of these and other limitations and losses, it
had been possible, in practice, to obtain only about two hundred and fifty
barrels of clinker per day of twenty-four hours; and that with an expenditure
for coal proportionately equal to about 29 to 33 per cent. of the quantity of
clinker produced, even assuming that all the clinker was of good quality.
Edison realized that the secret of greater commercial efficiency and
improvement of quality lay in the ability to handle larger quantities of
material within a given time, and to produce a more perfect product without
increasing cost or investment in proportion. His reasoning led him to the
conclusion that this result could only be obtained through the use of a kiln
of comparatively great length, and his investigations and experiments
enabled him to decide upon a length of one hundred and fifty feet, but with
an increase in diameter of only six inches to a foot over that of the sixty-
foot kiln.
material. In the sixty-foot kiln the length of the combustion zone was about
ten feet, extending from a point six or eight feet from the lower, or
discharge, end to a point about eighteen feet from that end. Consequently,
beyond that point there was a zone of only about forty feet, through which
the heated gases passed and came in contact with the oncoming material,
which was in movement down toward the clinkering zone. Since the bulk of

The principal considerations that influenced Edison in making this
radical innovation may be briefly stated as follows:
First. The ability to maintain in the kiln a load from five to seven times
greater than ordinarily employed, thereby tending to a more economical
output.
Second. The combustion of a vastly increased bulk of pulverized coal and
a greatly enlarged combustion zone, extending about forty feet
longitudinally into the kiln—thus providing an area within which the
material might be maintained in a clinkering temperature for a sufficiently
long period to insure its being thoroughly clinkered from periphery to
centre.
Third. By reason of such a greatly extended length of the zone of
oncoming material (and consequently much greater bulk), the gases and
other products of combustion would be cooled sufficiently between the
combustion zone and the stack so as to leave the kiln at a comparatively
low temperature. Besides, the oncoming material would thus be gradually
raised in temperature instead of being heated abruptly, as in the shorter
kilns.
Fourth. The material having thus been greatly raised in temperature
before reaching the combustion zone would have parted with substantially
all its carbon dioxide, and therefore would not introduce into the
combustion zone sufficient of that gas to disturb the perfect character of the
combustion.
Fifth. On account of the great weight of the heavy load in a long kiln,
there would result the formation of a continuous plastic coating on that
portion of the inner surface of the kiln where temperatures are highest. This
would effectively protect the fire-brick lining from the destructive effects of
the heat.
Such, in brief, were the essential principles upon which Edison based his
conception and invention of the long kiln, which has since become so well
known in the cement business.
Many other considerations of a minor and mechanical nature, but which
were important factors in his solution of this difficult problem, are worthy
of study by those intimately associated with or interested in the art. Not the
least of the mechanical questions was settled by Edison's decision to make
this tremendously long kiln in sections of cast-iron, with flanges, bolted

Page 621
together, and supported on rollers rotated by electric motors. Longitudinal
expansion and thrust were also important factors to be provided for, as well
as special devices to prevent the packing of the mass of material as it passed
in and out of the kiln. Special provision was also made for injecting streams
of pulverized coal in such manner as to create the largely extended zone of
combustion. As to the details of these and many other ingenious devices, we
must refer the curious reader to the patents, as it is merely intended in these
pages to indicate in a brief manner the main principles of Edison's notable
inventions. The principal United States patent on the long kiln was issued
October 24, 1905, No. 802,631.
That his reasonings and deductions were correct in this case have been
indubitably proven by some years of experience with the long kiln in its
ability to produce from eight hundred to one thousand barrels of good
clinker every twenty-four hours, with an expenditure for coal
proportionately equal to about only 20 per cent. of the quantity of clinker
produced.
To illustrate the long cement kiln by diagram would convey but little to
the lay mind, and we therefore present an illustration (Fig. 1) of actual kilns
in perspective, from which sense of their proportions may be gathered.

XVIII. EDISON'S NEW STORAGE BATTERY
GENERICALLY considered, a "battery" is a device which generates
electric current. There are two distinct species of battery, one being known
as "primary," and the other as "storage," although the latter is sometimes
referred to as a "secondary battery" or "accumulator." Every type of each of
these two species is essentially alike in its general make-up; that is to say,
every cell of battery of any kind contains at least two elements of different
nature immersed in a more or less liquid electrolyte of chemical character.
On closing the circuit of a primary battery an electric current is generated
by reason of the chemical action which is set up between the electrolyte and
the elements. This involves a gradual consumption of one of the elements
and a corresponding exhaustion of the active properties of the electrolyte.
By reason of this, both the element and the electrolyte that have been used
up must be renewed from time to time, in order to obtain a continued supply
of electric current.
The storage battery also generates electric current through chemical
action, but without involving the constant repriming with active materials to
replace those consumed and exhausted as above mentioned. The term
"storage," as applied to this species of battery, is, however, a misnomer, and
has been the cause of much misunderstanding to nontechnical persons. To
the lay mind a "storage" battery presents itself in the aspect of a device in
which electric energy is STORED, just as compressed air is stored or
accumulated in a tank. This view, however, is not in accordance with facts.
It is exactly like the primary battery in the fundamental circumstance that
its ability for generating electric current depends upon chemical action. In
strict terminology it is a "reversible" battery, as will be quite obvious if we
glance briefly at its philosophy. When a storage battery is "charged," by
having an electric current passed through it, the electric energy produces a
chemical effect, adding oxygen to the positive plate, and taking oxygen
away from the negative plate. Thus, the positive plate becomes oxidized,
and the negative plate reduced. After the charging operation is concluded
the battery is ready for use, and upon its circuit being closed through a
translating device, such as a lamp or motor, a reversion ("discharge") takes

Page 623
place, the positive plate giving up its oxygen, and the negative plate being
oxidized. These chemical actions result in the generation of an electric
current as in a primary battery. As a matter of fact, the chemical actions and
reactions in a storage battery are much more complex, but the above will
serve to afford the lay reader a rather simple idea of the general result
arrived at through the chemical activity referred to.
The storage battery, as a commercial article, was introduced into the
market in the year 1881. At that time, and all through the succeeding years,
until about 1905, there was only one type that was recognized as
commercially practicable—namely, that known as the lead-sulphuric-acid
cell, consisting of lead plates immersed in an electrolyte of dilute sulphuric
acid. In the year last named Edison first brought out his new form of nickel-
iron cell with alkaline electrolyte, as we have related in the preceding
narrative. Early in the eighties, at Menlo Park, he had given much thought
to the lead type of storage battery, and during the course of three years had
made a prodigious number of experiments in the direction of improving it,
probably performing more experiments in that time than the aggregate of
those of all other investigators. Even in those early days he arrived at the
conclusion that the lead-sulphuric-acid combination was intrinsically
wrong, and did not embrace the elements of a permanent commercial
device. He did not at that time, however, engage in a serious search for
another form of storage battery, being tremendously occupied with his
lighting system and other matters.
It may here be noted, for the information of the lay reader, that the lead-
acid type of storage battery consists of two or more lead plates immersed in
dilute sulphuric acid and contained in a receptacle of glass, hard rubber, or
other special material not acted upon by acid. The plates are prepared and
"formed" in various ways, and the chemical actions are similar to those
above stated, the positive plate being oxidized and the negative reduced
during "charge," and reversed during "discharge." This type of cell,
however, has many serious disadvantages inherent to its very nature. We
will name a few of them briefly. Constant dropping of fine particles of
active material often causes short-circuiting of the plates, and always
necessitates occasional washing out of cells; deterioration through
"sulphation" if discharge is continued too far or if recharging is not
commenced quickly enough; destruction of adjacent metalwork by the
corrosive fumes given out during charge and discharge; the tendency of
oxidized. These chemical actions result in the generation of an electric
current as in a primary battery. As a matter of fact, the chemical actions and
reactions in a storage battery are much more complex, but the above will
serve to afford the lay reader a rather simple idea of the general result

lead plates to "buckle" under certain conditions; the limitation to the use of
glass, hard rubber, or similar containers on account of the action of the acid;
and the immense weight for electrical capacity. The tremendously complex
nature of the chemical reactions which take place in the lead-acid storage
battery also renders it an easy prey to many troublesome diseases.
In the year 1900, when Edison undertook to invent a storage battery, he
declared it should be a new type into which neither sulphuric nor any other
acid should enter. He said that the intimate and continued companionship of
an acid and a metal was unnatural, and incompatible with the idea of
durability and simplicity. He furthermore stated that lead was an
unmechanical metal for a battery, being heavy and lacking stability and
elasticity, and that as most metals were unaffected by alkaline solutions, he
was going to experiment in that direction. The soundness of his reasoning is
amply justified by the perfection of results obtained in the new type of
storage battery bearing his name, and now to be described.
The essential technical details of this battery are fully described in an
article written by one of Edison's laboratory staff, Walter E. Holland, who
for many years has been closely identified with the inventor's work on this
cell The article was published in the Electrical World, New York, April 28,
1910; and the following extracts therefrom will afford an intelligent
comprehension of this invention:
"The 'A' type Edison cell is the outcome of nine years of costly
experimentation and persistent toil on the part of its inventor and his
associates....
"The Edison invention involves the use of an entirely new voltaic
combination in an alkaline electrolyte, in place of the lead-lead-peroxide
combination and acid electrolyte, characteristic of all other commercial
storage batteries. Experience has proven that this not only secures durability
and greater output per unit-weight of battery, but in addition there is
eliminated a long list of troubles and diseases inherent in the lead-acid
combination....
"The principle on which the action of this new battery is based is the
oxidation and reduction of metals in an electrolyte which does not combine
with, and will not dissolve, either the metals or their oxides; and an
electrolyte, furthermore, which, although decomposed by the action of the
glass, hard rubber, or similar containers on account of the action of the acid;

battery, is immediately re-formed in equal quantity; and therefore in effect
is a CONSTANT element, not changing in density or in conductivity.
"A battery embodying this basic principle will have features of great
value where lightness and durability are desiderata. For instance, the
electrolyte, being a constant factor, as explained, is not required in any fixed
and large amount, as is the case with sulphuric acid in the lead battery; thus
the cell may be designed with minimum distancing of plates and with the
greatest economy of space that is consistent with safe insulation and good

The article then treats of Edison's investigations into means for
supporting and making electrical connection with the active materials,
Page 626
showing some of the difficulties encountered and the various discoveries
made in developing the perfected cell, after which the writer continues his
description of the "A" type cell, as follows:
"It will be seen at once that the construction of the two kinds of plate is
radically different. The negative or iron plate (Fig. 5) has the familiar flat-
pocket construction. Each negative contains twenty-four pockets—a pocket
being 1/2 inch wide by 3 inches long, and having a maximum thickness of a
little more than 1/8 inch. The positive or nickel plate (Fig. 6) is seen to
consist of two rows of round rods or pencils, thirty in number, held in a
vertical position by a steel support-frame. The pencils have flat flanges at
the ends (formed by closing in the metal case), by which they are supported
and electrical connection is made. The frame is slit at the inner horizontal
edges, and then folded in such a way as to make individual clamping-jaws
for each end-flange. The clamping-in is done at great pressure, and the
resultant plate has great rigidity and strength.
"The perforated tubes into which the nickel active material is loaded are
made of nickel-plated steel of high quality. They are put together with a
double-lapped spiral seam to give expansion-resisting qualities, and as an
additional precaution small metal rings are slipped on the outside. Each
tube is 1/4 inch in diameter by 4 1/8 inches long, add has eight of the
reinforcing rings.
"It will be seen that the 'A' positive plate has been given the theoretically
best design to prevent expansion and overcome trouble from that cause.
Actual tests, long continued under very severe conditions, have shown that
the construction is right, and fulfils the most sanguine expectations."
Mr. Holland in his article then goes on to explain the development of the
nickel flakes as the conducting factor in the positive element, but as this has
already been described in Chapter XXII, we shall pass on to a later point,
where he says:
"An idea of the conditions inside a loaded tube can best be had by
microscopic examination. Fig. 7 shows a magnified section of a regularly
loaded tube which has been sawed lengthwise. The vertical bounding walls
are edges of the perforated metal containing tube; the dark horizontal lines
are layers of nickel flake, while the light-colored thicker layers represent
the nickel hydrate. It should be noted that the layers of flake nickel extend
practically unbroken across the tube and make contact with the metal wall
made in developing the perfected cell, after which the writer continues his
description of the "A" type cell, as follows:
"It will be seen at once that the construction of the two kinds of plate is
radically different. The negative or iron plate (Fig. 5) has the familiar flat-
pocket construction. Each negative contains twenty-four pockets—a pocket
being 1/2 inch wide by 3 inches long, and having a maximum thickness of a
little more than 1/8 inch. The positive or nickel plate (Fig. 6) is seen to
consist of two rows of round rods or pencils, thirty in number, held in a
vertical position by a steel support-frame. The pencils have flat flanges at
the ends (formed by closing in the metal case), by which they are supported
and electrical connection is made. The frame is slit at the inner horizontal
edges, and then folded in such a way as to make individual clamping-jaws
for each end-flange. The clamping-in is done at great pressure, and the
resultant plate has great rigidity and strength.
"The perforated tubes into which the nickel active material is loaded are
made of nickel-plated steel of high quality. They are put together with a
double-lapped spiral seam to give expansion-resisting qualities, and as an
additional precaution small metal rings are slipped on the outside. Each
tube is 1/4 inch in diameter by 4 1/8 inches long, add has eight of the
reinforcing rings.
"It will be seen that the 'A' positive plate has been given the theoretically
best design to prevent expansion and overcome trouble from that cause.
Actual tests, long continued under very severe conditions, have shown that
the construction is right, and fulfils the most sanguine expectations."
Mr. Holland in his article then goes on to explain the development of the
nickel flakes as the conducting factor in the positive element, but as this has
already been described in Chapter XXII, we shall pass on to a later point,
where he says:
"An idea of the conditions inside a loaded tube can best be had by
microscopic examination. Fig. 7 shows a magnified section of a regularly
loaded tube which has been sawed lengthwise. The vertical bounding walls
are edges of the perforated metal containing tube; the dark horizontal lines
are layers of nickel flake, while the light-colored thicker layers represent
the nickel hydrate. It should be noted that the layers of flake nickel extend
practically unbroken across the tube and make contact with the metal wall
Page 627
at both sides. These metal layers conduct current to or from the active
nickel hydrate in all parts of the tube very efficiently. There are about three
hundred and fifty layers of each kind of material in a 4 1/8-inch tube, each
layer of nickel hydrate being about 0.01 inch thick; so it will be seen that
the current does not have to penetrate very far into the nickel hydrate—one-
half a layer's thickness being the maximum distance. The perforations of the
containing tube, through which the electrolyte reaches the active material,
are also shown in Fig. 7."
In conclusion, the article enumerates the chief characteristics of the
Edison storage battery which fit it preeminently for transportation service,
as follows: 1. No loss of active material, hence no sediment short-circuits.
2. No jar breakage. 3. Possibility of quick disconnection or replacement of
any cell without employment of skilled labor. 4. Impossibility of "buckling"
and harmlessness of a dead short-circuit. 5. Simplicity of care required. 6.
Durability of materials and construction. 7. Impossibility of "sulphation." 8.
Entire absence of corrosive fumes. 9. Commercial advantages of light
weight. 10. Duration on account of its dependability. 11. Its high practical
efficiency.

XIX. EDISON'S POURED CEMENT HOUSE
THE inventions that have been thus far described fall into two classes—
first, those that were fundamental in the great arts and industries which have
been founded and established upon them, and, second, those that have
entered into and enlarged other arts that were previously in existence. On
coming to consider the subject now under discussion, however, we find
ourselves, at this writing, on the threshold of an entirely new and
undeveloped art of such boundless possibilities that its ultimate extent can
only be a matter of conjecture.
Edison's concrete house, however, involves two main considerations, first
of which was the conception or creation of the IDEA—vast and
comprehensive—of providing imperishable and sanitary homes for the
wage-earner by molding an entire house in one piece in a single operation,
so to speak, and so simply that extensive groups of such dwellings could be
constructed rapidly and at very reasonable cost. With this idea suggested,
one might suppose that it would be a simple matter to make molds and pour
in a concrete mixture. Not so, however. And here the second consideration
presents itself. An ordinary cement mixture is composed of crushed stone,
sand, cement, and water. If such a mixture be poured into deep molds the
heavy stone and sand settle to the bottom. Should the mixture be poured
into a horizontal mold, like the floor of a house, the stone and sand settle,
forming an ununiform mass. It was at this point that invention commenced,
in order to produce a concrete mixture which would overcome this crucial
difficulty. Edison, with characteristic thoroughness, took up a line of
investigation, and after a prolonged series of experiments succeeded in
inventing a mixture that upon hardening remained uniform throughout its
mass. In the beginning of his experimentation he had made the conditions
of test very severe by the construction of forms similar to that shown in the
sketch below.
This consisted of a hollow wooden form of the dimensions indicated. The
mixture was to be poured into the hopper until the entire form was filled,
such mixture flowing down and along the horizontal legs and up the vertical
members. It was to be left until the mixture was hard, and the requirement

such mixture flowing down and along the horizontal legs and up the vertical
members. It was to be left until the mixture was hard, and the requirement
Page 629
of the test was that there should be absolute uniformity of mixture and mass
throughout. This was finally accomplished, and further invention then
proceeded along engineering lines looking toward the devising of a system
of molds with which practicable dwellings might be cast.
Edison's boldness and breadth of conception are well illustrated in his
idea of a poured house, in which he displays his accustomed tendency to
reverse accepted methods. In fact, it is this very reversal of usual procedure
that renders it difficult for the average mind to instantly grasp the full
significance of the principles involved and the results attained.
Up to this time we have been accustomed to see the erection of a house
begun at the foundation and built up slowly, piece by piece, of solid
materials: first the outer frame, then the floors and inner walls, followed by
the stairways, and so on up to the putting on of the roof. Hence, it requires a
complete rearrangement of mental conceptions to appreciate Edison's
proposal to build a house FROM THE TOP DOWNWARD, in a few hours,
with a freely flowing material poured into molds, and in a few days to take
away the molds and find a complete indestructible sanitary house, including
foundation, frame, floors, walls, stairways, chimneys, sanitary
arrangements, and roof, with artistic ornamentation inside and out, all in
one solid piece, as if it were graven or bored out of a rock.
To bring about the accomplishment of a project so extraordinarily broad
involves engineering and mechanical conceptions of a high order, and, as
we have seen, these have been brought to bear on the subject by Edison,
together with an intimate knowledge of compounded materials.
The main features of this invention are easily comprehensible with the
aid of the following diagrammatic sectional sketch:
It should be first understood that the above sketch is in broad outline,
without elaboration, merely to illustrate the working principle; and while
the upright structure on the right is intended to represent a set of molds in
position to form a three-story house, with cellar, no regular details of such a
building (such as windows, doors, stairways, etc.) are here shown, as they
would only tend to complicate an explanation.
It will be noted that there are really two sets of molds, an inside and an
outside set, leaving a space between them throughout. Although not shown
in the sketch, there is in practice a number of bolts passing through these
two sets of molds at various places to hold them together in their relative
throughout. This was finally accomplished, and further invention then
proceeded along engineering lines looking toward the devising of a system
of molds with which practicable dwellings might be cast.

outside set, leaving a space between them throughout. Although not shown
in the sketch, there is in practice a number of bolts passing through these
two sets of molds at various places to hold them together in their relative
Page 630
positions. In the open space between the molds there are placed steel rods
for the purpose of reinforcement; while all through the entire structure
provision is made for water and steam pipes, gas-pipes and electric-light
wires being placed in appropriate positions as the molds are assembled.
At the centre of the roof there will be noted a funnel-shaped opening.
Into this there is delivered by the endless chain of buckets shown on the left
a continuous stream of a special free-flowing concrete mixture. This
mixture descends by gravity, and gradually fills the entire space between
the two sets of molds. The delivery of the material—or "pouring," as it is
called—is continued until every part of the space is filled and the mixture is
even with the tip of the roof, thus completing the pouring, or casting, of the
house. In a few days afterward the concrete will have hardened sufficiently
to allow the molds to be taken away leaving an entire house, from cellar
floor to the peak of the roof, complete in all its parts, even to mantels and
picture molding, and requiring only windows and doors, plumbing, heating,
and lighting fixtures to make it ready for habitation.
In the above sketch the concrete mixers, A, B, are driven by the electric
motor, C. As the material is mixed it descends into the tank, D, and flows
through a trough into a lower tank, E, in which it is constantly stirred, and
from which it is taken by the endless chain of buckets and dumped into the
funnel-shaped opening at the top of the molds, as above described.
The molds are made of cast-iron in sections of such size and weight as
will be most convenient for handling, mostly in pieces not exceeding two
by four feet in rectangular dimensions. The subjoined sketch shows an
exterior view of several of these molds as they appear when bolted together,
the intersecting central portions representing ribs, which are included as
part of the casting for purposes of strength and rigidity.
The molds represented above are those for straight work, such as walls
and floors. Those intended for stairways, eaves, cornices, windows,
doorways, etc., are much more complicated in design, although the same
general principles are employed in their construction.
While the philosophy of pouring or casting a complete house in its
entirety is apparently quite simple, the development of the engineering and
mechanical questions involves the solution of a vast number of most
intricate and complicated problems covering not only the building as a
whole, but its numerous parts, down to the minutest detail. Safety,
for the purpose of reinforcement; while all through the entire structure
provision is made for water and steam pipes, gas-pipes and electric-light
wires being placed in appropriate positions as the molds are assembled.

Section 4. Information about Donations to the Project
Gutenberg Literary Archive Foundation
Project Gutenberg™ depends upon and cannot survive without
widespread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine-readable form accessible by the widest
array of equipment including outdated equipment. Many small
donations ($1 to $5,000) are particularly important to maintaining tax
exempt status with the IRS.
The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United States.
Compliance requirements are not uniform and it takes a considerable
effort, much paperwork and many fees to meet and keep up with these
requirements. We do not solicit donations in locations where we have
not received written confirmation of compliance. To SEND
DONATIONS or determine the status of compliance for any particular
state visit www.gutenberg.org/donate.
While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who
approach us with offers to donate.
International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States. U.S. laws alone swamp our small staff.
Please check the Project Gutenberg web pages for current donation
methods and addresses. Donations are accepted in a number of other

Section 5. General Information About Project Gutenberg
electronic works
Professor Michael S. Hart was the originator of the Project Gutenberg
concept of a library of electronic works that could be freely shared
with anyone. For forty years, he produced and distributed Project
Gutenberg eBooks with only a loose network of volunteer support.
Project Gutenberg eBooks are often created from several printed
editions, all of which are confirmed as not protected by copyright in
the U.S. unless a copyright notice is included. Thus, we do not
necessarily keep eBooks in compliance with any particular paper
edition.
Most people start at our website which has the main PG search facility:
www.gutenberg.org.
This website includes information about Project Gutenberg, including
how to make donations to the Project Gutenberg Literary Archive
Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.
