Philo Taylor Farnsworth (August 19, 1906 \u2013 March 11, 1971) was an American inventor and television pioneer.^[2]^[3] He made the critical contributions to electronic television that made possible modern electronic video.^[4] He is best known for his 1927 invention of the first fully functional all-electronic image pickup device (video camera tube), the image dissector, as well as the first fully functional and complete all-electronic television system.^[5]^[6] Farnsworth developed a television system complete with receiver and camera\u2014which he produced commercially through the Farnsworth Television and Radio Corporation from 1938 to 1951, in Fort Wayne, Indiana.^[7]^[8]\n

In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth Fusor, employing inertial electrostatic confinement (IEC). Like many fusion devices, it was not a practical device for generating nuclear power, although it provides a viable source of neutrons.^[9] The design of this device has been the inspiration for other fusion approaches, including the Polywell reactor concept.^[10] Farnsworth held 300 patents, mostly in radio and television.\n
