Robert Horton (born Meade Howard Horton, Jr., on July 29, 1924, in Los Angeles, California) is an American television actor, who was most noted for the role from 1957 to 1962 of the frontier scout Flint McCullough in the NBC Western television series, Wagon Train. His costars were Ward Bond, John McIntire, Terry Wilson, and Frank McGrath. Horton quit that series to pursue a career in musical theater. His Wagon Train role was replaced by that of Robert Fuller as the scout Cooper Smith, and thereafter the series moved to ABC. Fuller, a veteran of the western series Laramie, resembled Horton and the two actors coincidentally shared the same birthday, albeit nine years apart.
