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 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end of the main axis, where the family and friends are likely to be found in the evening hours, unless the party has withdrawn for more intimate social intercourse to the interesting and fascinating private library on the floor above.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 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 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. To Edison, however, no trace of sentiment or regret occurred, and the whole 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 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 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.
