He was the Chief Inspector in The Pink Panther movies, sure. But more importantly, he was the child of Karl ze Schluderpacheru and his spouse Olga née Gottlieb who were members of Austrian nobility. If that's not celebrity, then we don't know what is.
Despite the fact that he was a founding member of Hell's Angels, spent a lot of time in prison for things like attempted murder, robbery and assault, and beat his wife and kid - this guy was pretty much a complete piece of garbage.
