Alexander Graham Bell was a British man who was a teacher to people who could not hear. He was born in Edinburgh , Scotland in 1847 and went to school in Edinburgh and London. People who cannot hear any sounds at all are called deaf people, and Alexander became interested in helping them to learn to speak. He taught people how to use their mouths to make the sounds needed for talking.

Bell’s family moved to Canada in 1870 and to the USA in 1871. For several years he taught the people who could not speak in Boston( 波士顿). But at the same time he was developing a way to use electricity to send the sounds of talking along a wire(电线), and he made the first telephone in June, 1875. He worked hard in his workshop for six months with his helper Tom Watson. Finally , he spoke these famous words slowly into the telephone, “Mr. Watson, come here. I want to see you.” And Watson came to him.

The telephone developed quickly in the USA over the next few years. The Bell Telephone Company started in 1877, and in 1878 the first telephone centre was built in New York. More than 150, 000 people had telephones in their homes ten years later. Alexander Graham Bell was a kind man and spent much of his money and time during the rest of his life helping deaf people . In 1922 he died in Canada.
