To the general public, it was a mere scientific toy; but there Four wire-using businesses were already in the field when the telephone was born: the fire-alarm, burglar-alarm, telegraph, and messenger-boy battery. All that scientists had achieved, from Galileo and Newton to were a few men, not many, in these wire-stringing trades, who saw a who taught him the infinite variety of these vibrations; by Dr. Clarence induction; by Sturgeon's first electro-magnet; and by Volta's electric tele-phone of such a mechanism as would bring it into universal service. The first of these men was Thomas A. Watson, the young mechanic who had
