Lawrence "Larry" Semon (July 6, 1889 – October 8, 1928) was an American actor, director, producer, and screenwriter during the silent film era. In his day, Semon was considered a major movie comedian, but he is now remembered mainly for working with both Stan Laurel and Oliver Hardy before they started working together. He is also sometimes noted for directing (as well as appearing in) the 1925 silent film Wizard of Oz,
