Robert Edward Crane (July 13, 1928 – June 29, 1978) was an American actor, drummer, radio personality, and disc jockey known for starring in the CBS situation comedy Hogan's Heroes.
Crane was a drummer from age 11, and he began his entertainment career as a radio personality, beginning in Hornell, New York and later in Connecticut. He then moved to Los Angeles, where he hosted the number-one rated morning radio show. In the early 1960s, Crane moved into acting, eventually landing the lead role of Colonel Robert Hogan in Hogan's Heroes. The series aired from 1965 to 1971, and Crane received two Emmy Award nominations.
Crane's career declined after Hogan's Heroes. He became frustrated with the few roles that he was being offered and began performing in dinner theater. In 1975, he returned to television with the NBC series The Bob Crane Show, but the series received poor ratings and was cancelled after thirteen weeks. Afterward, Crane returned to performing in dinner theater and also appeared in occasional guest spots on television.
Crane was found bludgeoned to death in his Scottsdale, Arizona, apartment while on tour in June 1978 for a dinner theater production of Beginner's Luck. In the 1990s, Crane's friend John Henry Carpenter was tried for the murder but was acquitted, and the case remains officially unsolved. Crane's previously uncontroversial public image suffered due to the suspicious nature of his death and posthumous revelations about his personal life.
