Alexander Graham Bell, teacher of the deaf, inventor, scientist (born 3 March 1847 in Edinburgh, Scotland; died 2 August 1922 near Baddeck, NS). Alexander Graham Bell is generally considered second only to Thomas Alva Edison among 19th- and 20th-century inventors. Although he is best known as the inventor of the first practical telephone, he also did innovative work in other fields, including aeronautics, hydrofoils and wireless communication (the “photophone”). Moreover, Bell himself considered his work with the deaf to be his most important contribution. Born in Scotland, he emigrated to Canada in 1870 with his parents. Bell married American Mabel Hubbard in 1877 and became a naturalized American citizen in 1882. From the mid-1880s, he and his family spent their summers near Baddeck on Cape Breton Island, where they built a large home, Beinn Bhreagh. From then on, Bell divided his time and his research between the United States and Canada. He died and was buried at Baddeck in 1922.
