Elmyr de Hory (born Elemér Hoffmann) (1905 – December 11, 1976) was a Hungarian-born painter and art forger who claimed to have sold over a thousand forgeries to reputable art galleries all over the world. His forgeries garnered much celebrity from a Clifford Irving book, Fake!, and from F for Fake (1974), a documentary essay film by Orson Welles.
