Philo Farnsworth

Farnsworth was born August 19, 1906, the eldest of five children of Lewis Edwin Farnsworth and Serena Amanda Bastian, a Latter-day Saint couple living in a small log cabin built by Lewis' father in Manderfield, near Beaver, Utah. His maternal grandfather, Jacob Bastian, was a Mormon immigrant from Denmark. where his father supplemented his farming income by hauling freight with his horse-drawn wagon. Philo was excited to find that his new home was wired for electricity, with a Delco generator providing power for lighting and farm machinery. He was a quick student in mechanical and electrical technology, repairing the troublesome generator. He found a burned-out electric motor among some items discarded by the previous tenants and rewound the armature; he converted his mother's hand-powered washing machine into an electric-powered one. He developed an early interest in electronics after his first telephone conversation with a distant relative, and he discovered a large cache of technology magazines in the attic of their new home. He won $25 in a pulp-magazine contest for inventing a magnetized car lock. Farnsworth excelled in chemistry and physics at Rigby High School. He asked science teacher Justin Tolman for advice about an electronic television system that he was contemplating; he provided the teacher with sketches and diagrams covering several blackboards to show how it might be accomplished electronically, and Tolman encouraged him to develop his ideas. One of the drawings that he did on a blackboard for his chemistry teacher was recalled and reproduced for a patent interference case between Farnsworth and RCA. In 1923, the family moved to Provo, Utah, and Farnsworth attended Brigham Young High School that fall. His father died of pneumonia in January 1924 at age 58, and Farnsworth assumed responsibility for sustaining the family while finishing high school. whom he eventually married. Farnsworth worked while his sister Agnes took charge of the family home and the second-floor boarding house, with the help of a cousin living with the family. The Farnsworths later moved into half of a duplex, with family friends the Gardners moving into the other side when it became vacant. He developed a close friendship with Pem's brother Cliff Gardner, who shared his interest in electronics, and the two moved to Salt Lake City to start a radio repair business. They agreed to fund his early television research with an initial $6,000 in backing, and set up a laboratory in Los Angeles for Farnsworth to carry out his experiments. Farnsworth married Pem on May 27, 1926, and the two traveled to Berkeley, California, in a Pullman coach. They rented a house at 2910 Derby Street, from which he applied for his first television patent, which was granted on August 26, 1930. By that time they had moved across the bay to San Francisco, where Farnsworth set up his new lab at 202 Green Street. ==Career==

A few months after arriving in California, Farnsworth was prepared to show his models and drawings to a patent attorney who was nationally recognized as an authority on electrophysics. Everson and Gorrell agreed that Farnsworth should apply for patents for his designs, a decision that proved crucial in later disputes with RCA. Most television systems in use at the time used image scanning devices ("rasterizers") employing rotating "Nipkow disks" comprising a spinning disk with holes arranged in spiral patterns such that they swept across an image in a succession of short arcs while focusing the light they captured on photosensitive elements, thus producing a varying electrical signal corresponding to the variations in light intensity. Farnsworth recognized the limitations of the mechanical systems, and that an all-electronic scanning system could produce a superior image for transmission to a receiving device. so the first image shown was, appropriately, a dollar sign. In 1929, the design was further improved by elimination of a motor-generator, which meant the television system now had no mechanical parts. During the same year, Farnsworth transmitted the first live human images with his system, including a image of his wife Elma ("Pem") with her eyes closed (possibly due to the bright lighting required). Many inventors had built electromechanical television systems before Farnsworth's seminal contribution, but Farnsworth designed and built the world's first working all-electronic television system, employing electronic scanning in both the pickup and display devices. He first demonstrated his system to the press on September 3, 1928, and to the public at the Franklin Institute in Philadelphia on August 25, 1934. In 1930, RCA recruited Vladimir K. Zworykin—who had tried, unsuccessfully, to develop his own all-electronic television system at Westinghouse in Pittsburgh since 1923—to lead its television development department. Before leaving his old employer, Zworykin visited Farnsworth's laboratory, and was sufficiently impressed with the performance of the Image Dissector that he reportedly had his team at Westinghouse make several copies of the device for experimentation. Zworykin later abandoned research on the Image Dissector, which at the time required extremely bright illumination of its subjects, and turned his attention to what became the Iconoscope. In a 1970s series of videotaped interviews, Zworykin recalled that, "Farnsworth was closer to this thing you're using now [i.e., a video camera] than anybody, because he used the cathode-ray tube for transmission. But, Farnsworth didn't have the mosaic [of discrete light elements], he didn't have storage. Therefore, [picture] definition was very low.... But he was very proud, and he stuck to his method." Contrary to Zworykin's statement, Farnsworth's patent number 2,087,683 for the Image Dissector (filed April 26, 1933) features the "charge storage plate" invented by Tihanyi in 1928 and a "low velocity" method of electron scanning, also describes "discrete particles" whose "potential" is manipulated and "saturated" to varying degrees depending on their velocity. Farnsworth's patent numbers 2,140,695 and 2,233,888 are for a "charge storage dissector" and "charge storage amplifier," respectively. In 1931, David Sarnoff of RCA offered to buy Farnsworth's patents for $100,000, with the stipulation that he become an employee of RCA, but Farnsworth refused. In June of that year, Farnsworth joined the Philco company and moved to Philadelphia along with his wife and two children. RCA later filed an interference suit against Farnsworth, claiming Zworykin's 1923 patent had priority over Farnsworth's design, despite the fact it could present no evidence that Zworykin had actually produced a functioning transmitter tube before 1931. Farnsworth had lost two interference claims to Zworykin in 1928, but this time he prevailed and the U.S. Patent Office rendered a decision in 1934 awarding priority of the invention of the image dissector to Farnsworth. RCA lost a subsequent appeal, but litigation over a variety of issues continued for several years before Sarnoff finally agreed to pay Farnsworth royalties. In 1932, while in England to raise money for his legal battles with RCA, Farnsworth met with John Logie Baird, a Scottish inventor who had given the world's first public demonstration of a working television system in London in 1926, using an electro-mechanical imaging system, and who was seeking to develop electronic television receivers. Baird demonstrated his mechanical system for Farnsworth. In May 1933, Philco severed its relationship with Farnsworth because, said Everson, "it [had] become apparent that Philo's aim at establishing a broad patent structure through research [was] not identical with the production program of Philco." In Everson's view the decision was mutual and amicable. Farnsworth set up shop at 127 East Mermaid Lane in Philadelphia, and in 1934 held the first public exhibition of his device at the Franklin Institute in that city. After sailing to Europe in 1934, Farnsworth secured an agreement with Goerz-Bosch-Fernseh in Germany. Farnsworth returned to his laboratory, and by 1936 his company was regularly transmitting entertainment programs on an experimental basis. That same year, while working with University of Pennsylvania biologists, Farnsworth developed a process to sterilize milk using radio waves. He also invented a fog-penetrating beam for ships and airplanes. In 1938, Farnsworth established the Farnsworth Television and Radio Corporation in Fort Wayne, Indiana, with E. A. Nicholas as president and himself as director of research. In 1967, Farnsworth and his family moved back to Utah to continue his fusion research at Brigham Young University, which presented him with an honorary doctorate. The university also offered him office space and an underground concrete bunker for the project. Realizing ITT would dismantle its fusion lab, Farnsworth invited staff members to accompany him to Salt Lake City, as team members in Philo T. Farnsworth Associates (PTFA). By late 1968, the associates began holding regular business meetings and PTFA was underway. They promptly secured a contract with the National Aeronautics and Space Administration (NASA), and more possibilities were within reach—but financing stalled for the $24,000 a month required for salaries and equipment rental. "We were watching it, and, when Neil Armstrong landed on the moon, Phil turned to me and said, 'Pem, this has made it all worthwhile.' Before then, he wasn't too sure." By Christmas 1970, PTFA had failed to secure the necessary financing, and the Farnsworths had sold all their own ITT stock and cashed in Philo's life insurance policy to maintain organizational stability. The underwriter had failed to provide the financial backing that was to have supported the organization during its critical first year. The banks called in all outstanding loans, repossession notices were placed on anything not previously sold, and the Internal Revenue Service put a lock on the laboratory door until delinquent taxes were paid. In January 1971, PTFA disbanded. Farnsworth became dependant on alcohol in his later years. He became seriously ill with pneumonia, and died on March 11, 1971, aged 64, at his home in Holladay, Utah. He was survived by his wife and their two sons. In 1999, Time magazine included Farnsworth in the "Time 100: The Most Important People of the Century". ==Inventions==

Electronic television Farnsworth worked out the principle of the image dissector in the summer of 1921, not long before his 15th birthday, and demonstrated the first working version on September 7, 1927, having turned 21 the previous August. A farm boy, his inspiration for scanning an image as a series of lines came from the back-and-forth motion used to plow a field. In the course of a patent interference suit brought by the Radio Corporation of America in 1934 and decided in February 1935, his high school chemistry teacher, Justin Tolman, produced a sketch he had made of a blackboard drawing Farnsworth had shown him in spring 1922. Farnsworth won the suit; RCA appealed the decision in 1936 and lost. Farnsworth received royalties from RCA, but he never became wealthy. The video camera tube that evolved from the combined work of Farnsworth, Zworykin, and many others was used in all television cameras until the late 20th century, when alternate technologies such as charge-coupled devices began to appear. Farnsworth also developed the "image oscillite", a cathode ray tube that displayed the images captured by the image dissector. Farnsworth called his device an image dissector because it converted individual elements of the image into electricity one at a time. He replaced the spinning disks with cesium, an element that emits electrons when exposed to light. In 1984, Farnsworth was inducted into the National Inventors Hall of Fame. Fusor The Farnsworth fusor is an apparatus designed by Farnsworth to create nuclear fusion. Unlike most controlled fusion systems, which slowly heat a magnetically confined plasma, the fusor injects high-temperature ions directly into a reaction chamber, thereby avoiding a considerable amount of complexity. When the Farnsworth fusor was first introduced to the fusion research world in the late 1960s, the fusor was the first device that could clearly demonstrate it was producing fusion reactions at all. Hopes at the time were high that it could be quickly developed into a practical power source. However, as with other fusion experiments, development into a power source has proven difficult. Nevertheless, the fusor has since become a practical neutron source and is produced commercially for this role. Other inventions At the time he died, Farnsworth held 300 U.S. and foreign patents. His inventions contributed to the development of radar, infra-red night vision devices, the electron microscope, the baby incubator, the gastroscope, and the astronomical telescope. ==TV appearance==

Although he was the man responsible for its technology, Farnsworth appeared only once on a television program. On July 3, 1957, he was a mystery guest ("Doctor X") on the CBS quiz show ''I've Got A Secret''. He fielded questions from the panel as they unsuccessfully tried to guess his secret ("I invented electronic television."). For stumping the panel, he received $80 and a carton of Winston cigarettes. Farnsworth said, "There had been attempts to devise a television system using mechanical disks and rotating mirrors and vibrating mirrors—all mechanical. My contribution was to take out the moving parts and make the thing entirely electronic, and that was the concept that I had when I was just a freshman in high school in the Spring of 1921 at age 14." A letter to the editor of the Idaho Falls Post Register disputed that Farnsworth had made only one television appearance. Roy Southwick claimed "... I interviewed Mr. [Philo] Farnsworth back in 1953—the first day KID-TV went on the air." KID-TV, which later became KIDK-TV, was then located near the Rigby area where Farnsworth grew up. ==Legacy==
