Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971) was an American inventor and television pioneer. [2][3] He made the critical contributions to electronic television that made possible all the video in the world today. [4] He is best known for his 1927 invention of the first fully functional all-electronic image pickup device (video ...
A Farnsworth–Hirsch fusor is the most common type of fusor. [1] This design came from work by Philo T. Farnsworth in 1964 and Robert L. Hirsch in 1967. [2] [3] A variant type of fusor had been proposed previously by William Elmore, James L. Tuck, and Ken Watson at the Los Alamos National Laboratory [4] though they never built the machine.
Image dissector. An image dissector, also called a dissector tube, is a video camera tube in which photocathode emissions create an " electron image" which is then swept up, down and across an anode to produce an electrical signal representing the visual image. It employs magnetic fields to keep the electron image in focus, and later models ...
In his work with vacuum tubes, Philo Farnsworth observed that electric charge accumulated in the tube. In 1962, Farnsworth patented a design using a positive inner cage to concentrate plasma and fuse protons. [35] During this time, Robert L. Hirsch joined Farnsworth Television labs and began work on what became the Farnsworth-Hirsch Fusor.
David Sarnoff. David Sarnoff (February 27, 1891 – December 12, 1971) was a Russian [4] and American businessman who played an important role in the American history of radio and television. He led RCA for most of his career in various capacities from shortly after its founding in 1919 until his retirement in 1970.
A fusor, exhibiting nuclear fusion in star mode. Inertial electrostatic confinement, or IEC, is a class of fusion power devices that use electric fields to confine the plasma rather than the more common approach using magnetic fields found in magnetic confinement fusion (MCF) designs. Most IEC devices directly accelerate their fuel to fusion ...
The Farnsworth Invention is a stage play by Aaron Sorkin adapted from an unproduced screenplay about Philo Farnsworth 's first fully functional and completely all-electronic television system and David Sarnoff, the RCA president who stole the design.
Such a television was produced by Philo Farnsworth, who demonstrated crude silhouette images to his family in Idaho on September 7, 1927. [35] Farnsworth's device would compete with the concurrent work of Kalman Tihanyi and Vladimir Zworykin. Though the execution of the device was not yet what everyone hoped it could be, it earned Farnsworth a ...
