Inventor Philo Taylor Farnsworth was born on August 19, 1906, in Beaver, Utah. He was born in a log cabin constructed by his grandfather, a Church of Jesus Christ of Latter Day Saints pioneer. An amateur scientist at a young age, Farnsworth converted his family's home appliances to electric power during his high school years and won a national contest with his original invention of a tamper-proof lock.
In his chemistry class in Rigby, Idaho, Farnsworth sketched out an idea for a vacuum tube that would revolutionize television — although neither his teacher nor his fellow students grasped the implications of his concept.
Farnsworth continued his studies at Brigham Young University, where he matriculated in 1922. He was forced to drop out following the death of his father two years later. His plans and experiments continued nonetheless.
By 1926, he was able to raise the funds to continue his scientific work and move to San Francisco with his new wife, Elma "Pem" Gardner Farnsworth. The following year, he unveiled his all-electronic television prototype—the first of its kind—made possible by a video camera tube or "image dissector." This was the same device that Farnsworth had sketched in his chemistry class as a teenager.
Farnsworth rejected the first offer he received from RCA to purchase the rights to his device. He instead accepted a position at Philco in Philadelphia, moving across the country with his wife and young children. Throughout the late 1920s and early 1930s, Farnsworth fought legal charges that his inventions were in violation of a patent filed prior to his by the inventor Vladimir Zworkyin. RCA, which owned the rights to Zworkyin's patents, supported these claims throughout many trials and appeals, with considerable success.
In 1933, the embattled Farnsworth left Philco to pursue his own avenues of research. Farnsworth's contributions to science after leaving Philco were significant and far-reaching. Some were unrelated to television, including a process he developed to sterilize milk using radio waves. He also continued to push his ideas regarding television transmission.
In 1938, he founded the Farnsworth Television and Radio Corporation in Fort Wayne, Indiana. RCA was ultimately able to market and sell the first electronic televisions for a home audience, after paying Farnsworth a fee of a million dollars.
