INTRODUCTION

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.

EDISON HIS LIFE AND INVENTIONS

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 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 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 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 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 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.
