In 1893 Charles Jenkins (1867-1934) created the forerunner to the motion picture projector. By 1924 he had invented the phantascope, one of the earliest succesful motion picture projectors. In 1925 he invented an experimental television system that worked on a mechanical scene-scanning method and his first 'radiovision' broadcast took place in June of that year when he transmitted moving pictures of a windmill.
