John Randolph Webb (April 2, 1920 – December 23, 1982) was an American actor, television producer, director, and screenwriter,
who is most famous for his role as Sgt. Joe Friday in the Dragnet franchise (which he also created). He was the founder of his own production company, Mark VII
Limited. Following his discharge, he moved to San Francisco, where a wartime shortage of announcers led to a temporary appointment to his own radio show on ABC's
KGO Radio. The Jack Webb Show was a half-hour comedy that had a limited run on ABC radio in 1946. Prior to that, he had a one-man program, One Out of Seven,
on KGO in which he dramatized a news story from the previous week.
