Roscoe Conkling "Fatty" Arbuckle (March 24, 1887 – June 29, 1933) was an American silent film actor, comedian, director, and screenwriter. Starting at the Selig Polyscope Company he eventually moved to Keystone Studios where he worked with Mabel Normand and Harold Lloyd. He mentored Charlie Chaplin and discovered Buster Keaton and Bob Hope.
He was one of the most popular silent stars of the 1910s, and soon became one of the highest paid actors in Hollywood, signing a contract to make $1 million a year in 1918.
In 1921, Arbuckle threw a party at the St. Francis Hotel in San Francisco during the Labor Day weekend. Bit player Virginia Rappe became ill at the party and died days later. Soon, Arbuckle was accused of raping and accidentally killing Rappe, enduring three widely publicized trials for manslaughter. His films were subsequently banned and he was publicly ostracized.
