“ In 1927, at the age of 21, Farnsworth completed the prototype of the first working fully electronic TV system, based on this “image dissector.” He soon found himself embroiled in a long legal battle with RCA, which claimed Zworykin’s 1923 patent took priority over Farnsworth’s inventions. The U.S. Patent Office ruled in favor of Farnsworth in 1934 (helped in part by an old high school teacher, who had kept a key drawing by the young inventor), and Sarnoff was eventually forced to pay Farnsworth $1 million in licensing fees. Though viewed by many historians as the true father of television, Farnsworth never earned much more from his invention, and was dogged by patent appeal lawsuits from RCA. He later moved on to other fields of research, including nuclear fission, and died in debt in 1971.”
