James Buchanan Eads was born in Lawrenceburg, Indiana, May 23, 1820. Both the Eads family, who came from Maryland, and his mother's people, the Buchanans, who were originally Irish, were gentlefolk; but James's father never was very prosperous. The son, however, went to school, and he showed early a very special love for machinery, observing with great interest everything of that kind that he came upon. For a while the family lived in Cincinnati; from there they removed in 1829 to Louisville. In those days, when steamboats were the best of conveyances, the Ohio River formed a natural highway between the two towns. On the trip the small boy of nine hung around the engine of the boat, considering it with so much wonder and admiration that finally the engineer, who found him an apt pupil, explained the various parts of the mechanism to him. He really had understood his lesson well, for two years later, in the little workshop that his father had fitted up for him, he made a small engine which ran by steam. Besides he made models of sawmills, fire-engines, steamboats, and electrotyping machines. Except such chance instruction as that which he found on the boat, he had had no teaching in mechanics, but worked with the ingenuity of many a bright boy; for he is by no means the only one who ever took apart and put together the family clock, or even a lever-watch, with no other tool than a penknife. One of his inventions, which shows not so much his talent as his true boyishness, was a small box-wagon, open only underneath and with a hole in front, which, suddenly produced before his mother and sisters, ran mysteriously across the room. The motive power concealed within this agreeable toy was found to be a live rat. So much is often said of the precocity of youthful geniuses, that it is good to know that young Eads was after all a real flesh-and-blood boy, a boy so mischievous that, as he was the only son, his father hired a neighbor boy to come and play with him. Certainly he was very clever; but that he had even better qualities than cleverness is shown by his first actions on his arrival at Saint Louis.
