Isaac Sidney "Sid" Caesar was an American comic actor and writer, best known for the pioneering 1950s live television series Your Show of Shows, a 90-minute weekly show watched by 60 million people, and its successor Caesar's Hour, both of which influenced later generations of comedians. He also acted in movies; he played Coach Calhoun in Grease and its sequel Grease 2, and appeared in the films It's a Mad, Mad, Mad, Mad World, Silent Movie, History of the World, Part I, and Cannonball Run II.
Caesar was considered a "sketch comic" and actor, as opposed to a stand-up comedian. He also relied more on body language, accents, and facial contortions than simply dialogue. Unlike the slapstick comedy, which was standard on TV, his style was considered "avant garde" in the 1950s. He conjured up ideas and scenes, and used writers to flesh out the concept and create the dialogue. Among the writers who wrote for Caesar early in their careers were Mel Brooks, Neil Simon, Larry Gelbart, Carl Reiner, Michael Stewart, Mel Tolkin and Woody Allen. "Sid's was the show to which all comedy writers aspired. It was the place to be," said Steve Allen.
