Richard Thomas was seven years old when he made his first Broadway appearance in Sunrise at Campobello (1958). The wide-eyed, mole-cheeked, sensitive-looking Thomas soon found himself very much in demand for television roles. He was seen in the distinguished company of Julie Harris, Christopher Plummer and Hume Cronyn in a 1959 TV presentation of Ibsen's A Doll's House, worked as a regular on the daytime soap operas As the World Turns and Flame in the Wind, and co-starred with Today Show announcer Jack Lescoulie in the captivating 1961 Sunday-afternoon "edutainment" series 1-2-3 Go. While attending Columbia University, Thomas made his theatrical-film debut in Downhill Racer, then settled into a series of unpleasant, psychologically disturbed characters in films like You'll Like My Mother (1971) and such TV series as Bracken's World. In 1971, Thomas was cast as John-Boy Walton in the Earl Hamner-scripted TV movie The Homecoming. Though there would be a number of cast changes before The Homecoming metamorphosed into the weekly series The Waltons in 1972, Thomas was retained as John-Boy, earning a 1973 Emmy for his performance and remaining in the role until only a few months before the series' cancellation in 1981. During the Waltons years, Thomas starred in several well-mounted TV movies, including the 1979 remake of All Quiet on the Western Front.
