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. By this marriage there are three children—Charles, Madeline, and Theodore.
For over twenty years Edison's happy and perfect domestic life has been spent at Glenmont, a beautiful property in Llewellyn Park, on the Orange Mountain, New Jersey. Here, amid the comforts of a beautifully appointed home, in which may be seen the many decorations and medals awarded to him, together with the numerous souvenirs sent to him by foreign potentates and others, Edison spends the hours that he is away from the laboratory. They are far from being idle hours, for it is here that he may pursue his reading free from interruption.
His hours of sleep are few, not more than six in the twenty-four, and not as much as that when working nights at the laboratory. In a recent conversation a friend expressed surprise that he could stand the constant strain, to which Edison replied that he stood it easily, because he was interested in everything. He further said: "I don't live with the past; I am living for to-day and to-morrow. I am interested in every department of science, art, 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 some theatrical and sporting papers 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."
In conversation Edison is direct, courteous, ready to discuss a topic with anybody worth talking to, and, in spite of his deafness, an excellent listener. No one ever goes away from him in doubt as to what he thinks or means, but, with characteristic modesty, he is ever shy and diffident to a degree if the talk turns on himself rather than on his work.
He is a normal, fun-loving, typical American, ever ready to listen to a new story, with a smile all the while, and a hearty, boyish laugh at the end. He has a keen sense of humor, which manifests itself in witty repartee and in various ways.
In his association with his staff of experimenters the "old man," as he is affectionately called, is considerate and patient, although always insisting on absolute accuracy and exactness in carrying out his ideas. He makes liberal allowance for errors arising through human weakness of one kind or another, but a stupid mistake or an inexcusable oversight on the part of an assistant will call forth a storm of contemptuous expression that is calculated to make the offender feel cheap. The incident, however, is quickly a thing of the past, as a general rule.
If there is anything in heredity, Edison has many years of vigor and activity yet before him. What the future may have in store in the way of further achievement cannot be foreshadowed, for he is still a mighty thinker and a prodigy of industry and hard work.
