Scottish-born American inventor and teacher of the deaf,Alexander Graham Bell was best known for perfecting the telephone to transmit vocal messages by electricity. The telephone brought in a new age for communication in technology during this period of time.

Inventing The Telephone

To help deaf children, Alexander experimented with a human ear, attached bones, magnets and tympanum in the summer of 1874. He came up with the theory of the telephone when experimenting with electric currents one day. As he was experimenting with the currents, he then realized the currents changed intensity as air density varied during sound production. The telephone required continuous current with varying intensity. That same year Bell invented a harmonic telegraph to transmit several messages all at once. He wanted the messages to be easily received over one wire to a telephonic telegraphic receiver. Trying to reproduce the human voice electrically, Bell became an expert with electric wave transmission and from there on it was a breeze to create the telephone and function it.

Establishing an Industry

The first two way conversation on the phone that Bell invented was between him and Christopher Watson on the day of October 9,1876. In 1877 the very first telephone was installed in a private home in the town of Cambridge Massachusetts. Their conversation was continued from Boston to New York using telegraphic lines. In July the first organization to commercialize the invention, The Bell Telephone Company was formed.
