Bob Crane’s addiction to sex: Crane is best remembered as Colonel Robert E. Hogan on the family-friendly sitcom “Hogan’s Heroes.” But the fact that he had a secret sex life didn’t come into light until the investigation of his murder (he was bludgeoned to death) in 1978. For years, Crane would videotape himself in various sexual acts with different women. None of these videotapes included his wife, actress Sigrid Valdis, whom he was married to during his sexcapades and at the time of his death.
