Bell, Alexander Graham (1847–1922)
At age 23 Bell moved to Canada. In 1871, he began giving instruction in Visible Speech at the Boston School for Deaf Mutes. This background set his course in developing the transmission of voice over wires. He cofounded Bell Telephone Co. in 1877. With his father-in-law, he re-established the journal Science (1882).He also devised the wax-cylinder phonograph and helped perfect the aileron for airplanes.
