Alexander Graham Bell was born in Edinburgh Scotland in 1847. The family moved to Newfoundland Canada in 1870. Because of his mother's increasing deafness, Bell became interested in acoustics and sound transmission.
He moved to Boston Massachusetts to teach and continue his work on sound transmission. In 1876, he spoke to his assistant Watson who was in the next room through the first voice transmission device, saying "Watson, Come Here, I need to see you". Thus the telephone was invented.
