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 acting in films in the Biograph Company of New York City in 1908, 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. He also produced short features that displayed his Bathing Beauties, many of whom had acting careers.
After struggling with bankruptcy and the dominance of sound films in the early 1930s, Sennett was presented with an honorary Academy Award in 1938 for his contributions to the film industry, with the academy describing him as a "master of fun, discoverer of stars, sympathetic, kindly, understanding comedy genius".
