Oliver Crawford (August 12, 1917 – September 24, 2008) was an American screenwriter and author who overcame the Hollywood blacklist during the McCarthy Era of the 1950s to become one of the entertainment industry's most successful television writers. The list of shows for which he wrote for included Star Trek, Bonanza, Quincy, M.E., Perry Mason and the Kraft Television Theatre.
Born in Chicago, Illinois, Crawford attended the Chicago Art Institute and the Goodman Theatre school. His classmates at Goodman included Sam Wanamaker and Karl Malden, both of whom became lifelong friends of Crawford.
Crawford began working in the television industry as a writer in the early 1950s. By 1953, he had had contracted to work with both Harold Hecht and Burt Lancaster. Shortly after he signed his contract to work with Lancaster, Crawford was summoned in 1953 to appear before the House Un-American Activities Committee, which was investigating suspected Communist sympathizers in Hollywood. Crawford refused to name suspected Communists sympathizers within the entertainment industry. His refusal to implicate anyone in Hollywood led to his blacklisting. He was also fired from his 1953 contract.
