THE SOCIAL SIDE OF EDISON APPENDIX LIST OF UNITED STATES PATENTS FOREIGN PATENTS INDEXINTRODUCTIONPRIOR 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 anythi
6、ng 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 i
7、n 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
8、 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 f
9、acts 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 achievement
10、s 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 f
11、ace 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 d
12、eeply 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 lik
13、e 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
14、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 abs
15、truse 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 b
16、e 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 st
17、renuous 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. Edisons own language, from oral or written statements made in reply to questions addressed to him with the object of securing accuracy. A further large par
18、t 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.
19、 Mallory, an, 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 grou
20、p, classify, and summarize the boundless material embodied in Edisons 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 he
21、r private collection.EDISONHIS LIFE AND INVENTIONSCHAPTER ITHE AGE OF ELECTRICITYTHE 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 Or
22、egon 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 m
23、elodramatic 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 e
24、ntire 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 Mex
25、ico 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 g
26、overnment 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
27、 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, jou
28、rnalists, 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 sober
29、ing 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 pas
30、t 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
31、 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
32、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
33、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 Edisons share in the great work of the last half century in abridging distance, communicating intelligence, lessening toil, improving illumination, recording foreve
34、r 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 centur
35、y 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
36、 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 be
37、en 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 ind
38、efinitely 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 emb
39、ryonic 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
40、 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 il
41、limitable 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 eig
42、hteenth 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 identit
43、y 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 f
44、ew 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 natures daily food that the average American to-day pays more for his electrical service than he does for bread.With the fir
45、st year of the new century came Voltas 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 ephe
46、meral empire. At such a moment this gift of de- spoiled 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 th
47、e 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
48、 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 the
