Lee De Forest
Lee de Forest — American inventor (1873–1961)
Lee de Forest was an American inventor, electrical engineer, and early pioneer in electronics of fundamental importance. He invented the first practical electronic amplifier, the three-element "Audion" triode vacuum tube in 1908. This helped start the Electronic Age, and enabled the development of the electronic oscillator. These made radio broadcasting and long-distance telephone lines possible, and led to the development of talking motion pictures, among countless other applications.
