At five years of age, little John J. Carty was taken by his father to the shop where the bells were made, and he was profoundly impressed by the magical strength of a big magnet, that picked up heavy weights as though they were feathers. At the high school his favorite study was physics; and for a time he and another boy named Rolfe--now a distinguished man of science--carried on electrical experiments of their own in the cellar of the Rolfe house. Here they had a "Tom Thumb" telegraph, a telephone which they had ventured to improve, and a hopeless tangle of wires. Whenever they could afford to buy more wires and batteries, they went to a near-by store which supplied electrical apparatus to the professors and students of Harvard. This store, with its workshop in the rear, seemed to the two boys a veritable wonderland; and when Carty, a youth of eighteen, was compelled to leave school because of his bad eyesight, he ran at once and secured the glorious job of being boy-of-all-work in this store of wonders. So, when he became an operator in the Boston telephone exchange, a year later, he had already developed to a remarkable degree his natural genius for telephony. Since then, Carty and the telephone business have grown up together, he always a little distance in advance. No other man has touched the apparatus of telephony at so many points. He fought down the flimsy, clumsy methods, which led from one snarl to another. He found out how to do with wires what Dickens did with words. "Let us do it right, boys, and then we won't have any bad dreams"--this has been his motif. And, as the crown and climax of his work, he mapped out the profession of telephone engineering on the widest and most comprehensive lines. In Carty, the engineer evolved into the educator. His end of the American Telephone and Telegraph Company became the University of the Telephone. He was himself a student by disposition, with a special taste for the writings of Faraday, the forerunner; Tyndall, the expounder; and Spencer, the philosopher. And in 1890, he gathered around him a winnowed group of college graduates--he has sixty of them on his staff to-day--so that he might bequeath to the telephone an engineering corps of loyal and efficient men.
