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]
In January 1927, American inventor and television pioneer Philo T. Farnsworth applied for a patent for his Television System that included a device for "the conversion and dissecting of light". [20] Its first moving image was successfully transmitted on September 7 of 1927, [24] and a patent was issued in 1930. [20]
[11] [12] By September 3, 1928, Farnsworth had developed the system sufficiently to hold a demonstration for the press, [12] the first such successful demonstration of a fully electronic television system. [12] In 1929 Farnsworth eliminated a motor generator from the system, so it then had no mechanical parts. Further developments that year ...
Philo Farnsworth achieves an experimental electronic television image, of a straight line, at his laboratory at 202 Green Street in San Francisco. [4] 20: John Logie Baird demonstrates the first ever system for recording television. His Phonovision VideoDisc apparatus records 30-line television pictures and sound on conventional 78 rpm ...
This was the first fully electronic system to replace earlier cameras, which used special spotlights or spinning disks to capture light from a single very brightly lit spot. Some of the principles of this apparatus were described when Vladimir Zworykin filed two patents for a television system in 1923 and 1925.
September 7 – On September 7, 1927, Philo Farnsworth's image dissector camera tube transmitted its first image, a simple straight line, at his laboratory at 202 Green Street in San Francisco. [6] [7] Specific date unknown – In 1927, the American physicist Frank Gray proposed an early form of the flying-spot scanner for use in early TV ...
In 1929, Farnsworth's system was further improved by the elimination of a motor generator. Consequently, his television system had no mechanical parts. [8] During the same year, Farnsworth transmitted the first live human images with his system, including a 3.5 in (89 mm) image of his wife Elma ("Pem") with her eyes closed (possibly due to the ...
At his laboratory at 202 Green Street in San Francisco, Philo T. Farnsworth demonstrated the first completely electronic television system. Although mechanical television , using a rotating disk, had been created earlier by John Logie Baird , the hardware limited the picture to 10 frames per second and a 30-line image.
