Inventor

Teacher

Alexander Graham Bell's most famous invention, the telephone, was the result of his primary career focus: teaching the deaf to speak. Bell had been successful in his work with the hearing-impaired and had instructed a generation of teachers in his methods. He sought to reproduce human speech by creating a machine with a wire that could be vibrated by the voice. Backed by a team of eager financial supporters, Bell and his assistant, Thomas Watson (1854–1934), perfected their speech-transmission device in March 1876. Their invention revolutionized communication and created an entirely new industry.
