Caption: "An actor portraying Alexander Graham Bell speaking into a early model of the telephone for a 1926 promotional film by the American Telephone & Telegraph Company (AT&T)." Alexander Graham Bell (March 3, 1847 - August 2, 1922) was a Scottish-American speech therapist and inventor of the telephone. Bell followed his father and grandfather into the speech therapy profession, but also studied sound waves and the mechanics of speech. By 1871, he had moved to the USA, becoming professor of vodal physiology in Boston. There he performed his experiments in converting sound waves into electrical impulses for transmission down wires. In 1876, he patented the telephone and founded what has become the AT&T company. In later years he made many improvements to the telephone, worked with Langley and Curtis on flying machines, and founded the journal "Science." He died of complications arising from diabetes in 1922 at the age of 75. His coffin was constructed of Beinn Bhreagh pine by his laboratory staff, lined with the same red silk fabric used in his tetrahedral kite experiments.
