Answer:
Philo Farnsworth, in full Philo Taylor Farnsworth II, (born August 19, 1906, Beaver, Utah, U.S.—died March 11, 1971, Salt Lake City, Utah), American inventor who developed the first all-electronic television system.
Farnsworth was a technical prodigy from an early age. An avid reader of science magazines as a teenager, he became interested in the problem of television and was convinced that mechanical systems that used, for example, a spinning disc would be too slow to scan and assemble images many times a second. Only an electronic system could scan and assemble an image fast enough, and by 1922 he had worked out the basic outlines of electronic television.
In 1923, while still in high school, Farnsworth also entered Brigham Young University in Provo, Utah, as a special student. However, his father’s death in January 1924 meant that he had to leave Brigham Young and work to support his family while finishing high school.
Farnsworth had to postpone his dream of developing television. In 1926 he went to work for charity fund-raisers George Everson and Leslie Gorrell. He convinced them to go into a partnership to produce his television system. Farnsworth moved to Los Angeles with his new wife, Pem Gardner, and began work. He quickly spent the original $6,000 put up by Everson and Gorrell, but Everson procured $25,000 and laboratory space from the Crocker First National Bank of San Francisco. Farnsworth made his first successful electronic television transmission on September 7, 1927, and filed a patent for his system that same year.
Explanation:
Farnsworth continued to perfect his system and gave the first demonstration to the press in September 1928. His backers at the Crocker First National Bank were eager to be bought out by a much larger company and in 1930 made overtures to the Radio Corporation of America (RCA), which sent the head of their electronic television project, Vladimir Zworykin, to evaluate Farnsworth’s work. Zworykin’s receiver, the kinescope, was superior to that of Farnsworth, but Farnsworth’s camera tube, the image dissector, was superior to that of Zworykin. Zworykin was enthusiastic about the image dissector, and RCA offered Farnsworth $100,000 for his work. He rejected the offer.
