John Emerson (born Clifton Paden; May 29, 1874 – March 7, 1956) was an American stage actor, playwright, producer, and director of silent films (many featuring Douglas Fairbanks). Emerson was married to Anita Loos from June 15, 1919, until his death, and prior to that the couple had worked together as a writing team for motion pictures. They would continue to be credited jointly, even as Loos pursued independent projects.
