| The Scottish-born scientist,
Alexander Graham Bell
(1847-1922), was always interested in
sound: his father was a speech expert
and his mother was deaf. In 1872, Bell founded a school for deaf-mutes in Boston and taught to deaf people. As a scientist, he was originally interested in multiple-telegraphy which would allow several messages to be sent at the same time along a wire. However, he soon found his experiments led him to the invention of the telephone.
