Few who tune into the WTTG television station in Washington, DC know that the letters refer to a real person. Thomas T. Goldsmith was an engineer for the DuMont television network. Its founder Allen DuMont was the technology hero of his day: in 1937, he began making the first cathode ray tubes that didn't burn out, which made television sets commercially viable. The era of "the tube" had begun. In 1946, his fledgling DuMont network demonstrated what TV could do, showing General Eisenhower laying a wreath on Lincoln's memorial to viewers in New York.
In 1947, DuMont employee Goldsmith patented a Cathode Ray Tube Amusement Device, or the world's first electronic game, but it was never manufactured.
