Mark Sennett

Mack Sennett was a Canadian-American producer, director, actor, and studio head who was known as the "King of Comedy" during his career. Born in Danville, Quebec, he started in films in the Biograph Company of New York City, and later opened Keystone Studios in Edendale, California in 1912. Keystone possessed the first fully enclosed film stage, and Sennett became famous as the originator of slapstick routines such as pie-throwing and car-chases, as seen in the Keystone Cops films.
