Bell kissing his wife Mabel, who is standing in a tetrahedral kite, Baddeck, Nova Scotia. 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. 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. Mabel Gardiner Hubbard (November 25, 1857 - January 3, 1923) was his wife. Folklore held that Bell undertook telecommunication experiments in an attempt to restore her hearing which had been destroyed by disease close to her 50th birthday.
