Keystone Studios was an early movie studio founded in Edendale, California (which is now a part of Echo Park) on July 4, 1912 as the Keystone Pictures Studio by Mack Sennett (1880-1960) with backing from actor-writer Adam Kessel (1866-1946) and Charles O. Baumann (1874-1931), owners of the New York Motion Picture Company (founded 1909). The company filmed in and around Glendale and Silver Lake, Los Angeles, California for several years, and its films were distributed by the Mutual Film Corporation between 1912 and 1915.
