David Doyle came from a line of lawyers that stretches back four generations. When he ranked sixth in the state of Nebraska on his law school entrance exams, and then began attending the University of Nebraska, it was expected that he would keep up the tradition. His brother John took that role, however, and David instead pursued his love of acting. During his college years, he made friends with classmate and fellow performer Johnny Carson, later dropping by "The Tonight Show" regularly. Doyle's first acting break came via Broadway, when he was called on to replace Walter Matthau in "Will Success Spoil Rock Hunter?" He worked primarily in television, making guest appearances on crime dramas such as "Hawaii Five-O" and having recurring roles like that of Ted Atwater on the sitcom "The New Dick Van Dyke Show." With his uniquely scratchy voice, Doyle also found a good deal of success behind the microphone for animated movies and series, namely his portrayal of Grandpa Lou Pickles on the Nickelodeon kids' show "Rugrats." However, he is probably best known for playing John Bosley, the right-hand man to Charlie and liaison to his Angels, in the iconic crime series "Charlie's Angels."
