Talk about Alexxander : graham Bell and his invention
Alexander Graham Bell was born in Edinburgh, Scotland. His family was known for teaching people how to speak English clearly (elocution). Both his grandfather, Alexander Bell, and his father, Alexander Melville Bell, taught elocution. His father wrote often about this and is most known for his invention and writings of Visible Speech.[1] In his writings he explained ways of teaching people who were deaf and unable to speak. It also showed how these people could learn to speak words by watching their lips and reading what other people were saying.
Alexander Graham Bell went to the Royal High School of Edinburgh. He graduated at the age of fifteen. At the age of sixteen, he got a job as a student and teacher of elocution and music in Weston House Academy, at Elgin in Morayshire. He spent the next year at the University of Edinburgh. While still in Scotland, he became more interested in the science of sound (acoustics). He hoped to help his deaf mother. From 1866 to 1867, he was a teacher at Somersetshire College in Bath, Somerset.
In 1870 when he was 23 years old, he moved with his family to Canada where they settled at Brantford, Ontario.[1] Bell began to studycommunication machines. He made a piano that could be heard far away by using electricity. In 1871 he went with his father to Montreal, Quebec in Canada, where he took a job teaching about "visible speech". His father was asked to teach about it at a large school for deaf mutes in Boston, Massachusetts, but instead he gave the job to his son. The younger Bell began teaching there in 1872.[1] Alexander Graham Bell soon became famous in the United States for this important work. He published many writings about it in Washington, D.C.. Because of this work, thousands of deaf mutes inAmerica are now able to speak, even though they cannot hear.
In 1876, Bell was the first inventor to patent the telephone, and he helped start the Bell Telephone Company with others in July 1877.[1] In 1879, this company joined with the New England Telephone Company to form the National Bell Telephone Company. In 1880, they formed the American Bell Telephone Company, and in 1885, American Telephone and Telegraph Company (AT&T), still a large company today. Along with Thomas Edison, Bell formed the Oriental Telephone Company on January 25, 1881.
Bell married Mabel Hubbard on July 11, 1877. He died of diabetes at his home near Baddeck, Nova Scotia in 1922.
