Allen Balcom DuMont, also spelled Du Mont, (January 29, 1901 – November 14, 1965) was an American electronics engineer, scientist and inventor best known for improvements to the cathode ray tube in 1931 for use in television receivers. Seven years later he manufactured and sold the first commercially practical television set to the public. In June 1938, his Model 180 television receiver was the first all-electronic television set ever sold to the public, a few months prior to RCA's first set in April 1939. In 1946, DuMont founded the first television network to be licensed, the DuMont Television Network, initially by linking station WABD (named for DuMont; it later became WNEW and is now WNYW) in New York City to station W3XWT, which later became WTTG, in Washington, D.C. (WTTG was named for Dr. Thomas T. Goldsmith, DuMont's Vice President of Research, and his best friend.) DuMont's successes in television picture tubes, TV sets and components and his involvement in commercial TV broadcasting made him the first millionaire in the business. Biography Early life DuMont was born in Brooklyn, New York City, the son of Lillian Felton (Balcom) and William Henry Beaman DuMont. At the age of 10, he was stricken with polio and was quarantined at his family's Eastern Parkway apartment for nearly a year. During his quarantine, his father brought home books and magazines for the young DuMont to read while bedridden. At this time, DuMont developed an interest in science, specifically wireless radio communication, and taught himself Morse code. His father bought him a crystal radio receiver, which he assembled, took apart, reassembled and rebuilt several times. He improved his set each time he rebuilt it and later built a transmitter, while his father obtained the landlord's permission to erect a transceiving antenna on the roof. While recuperating from polio, DuMont was advised to swim to regain the use of his legs. In 1914, the family moved to Montclair, New Jersey, where there was an indoor year-round pool available at the local YMCA. He graduated from Montclair High School in 1919, and went to Rensselaer Polytechnic Institute in Troy, New York, where he was part of the Alpha chapter of the Theta Xi fraternity. Radio and early interest in television In 1915, DuMont became the youngest American to obtain a first class commercial radio operator's license at age 14. The following summer, he worked as a radio
