While attending Brown University in Rhode Island, actor Don Haggerty was a star athlete. From there, he went on to serve in the United States military. His rugged athleticism would later come to serve him well in his career as a B-movie actor, where he would often play the roles of rough cowboys, ruthless mob men, macho policemen, sheriffs, and soldiers. He appeared in several theater productions and uncredited film roles before making his official film debut in 1947, appearing as Deputy Tom Emery in the western "Mystery Range." As a freelance actor, he was cast in productions for virtually every studio in Hollywood at the time. Some other films he appeared in include the John Wayne war picture "Sands of Iwo Jima" (1949), the John Huston-directed film noir "The Asphalt Jungle" (1950), and the crime drama "Chain of Evidence" (1957), where he received top billing along with Bill Elliott and Jimmy Lydon. In 1949, he made his first television appearance in the classic western series "The Lone Ranger," playing a member of a gang out to steal a young man's inheritance. From 1955 to 1961, he had a recurring role in "The Life and Legend of Wyatt Earp," playing Marsh Murdock, the editor of the "Wichita Eagle" newspaper. He continued to make film and television appearances until 1981, when he made his last appearance in the TV movie "California Gold Rush."
