Lee DeForest (1871-1961)

An American, often thought of as the “father of Radio” invented a vacuum tube in 1907 that could not only detect the signals but could amplify them to a level where they could be heard through a loud speaker.

Fleming and DeForest’s tubes made radios possible and led the way to television, radar, and computers.

In the mid 1800s television had its beginning as scientists attempted to send light images over a wire, but it was not until the late 1940s and early 1950s that television came into its own.
