Alexander Graham Bell (1847-1922)

Alexander Graham Bell Was born and educated in Scotland but lived for most of his life in the United States of America.
Before he left Scotland, Bell began teaching deaf children using a code of symbols invented by his father.
His interest in the human voice, and the realization that speech produces around waves vibrating in air,
led him to become the first person to successfully transmit speech by means of electrified wire .
In 1876, he announced the world's first workable Telephone. It had certain disadvantages;
it had to be moved quickly from mouth to earand the sound was very faint even when the speaker shouted.
The American inventor Edison soon produced a much more powerful and successful telephone.
In 1880, Bell brought out the Gramophone which was an improved version of Edison's phonograph,
a machine which recorded speech and played it back
Though Bell will always be associated with the invention of the telephone,
he would rather have been remembered as a teacher of the deaf.
