Elmyr de Hory (born Elemér Albert Hoffmann; Budapest, April 14, 1906 – Ibiza, December 11, 1976) was a Hungarian-born painter and art forger, who is said to have sold over a thousand forgeries to reputable art galleries all over the world. His forgeries garnered celebrity from a Clifford Irving book, Fake (1969); a documentary essay film by Orson Welles, F for Fake (1974); and a biography by Mark Forgy, "The Forger's Apprentice: Life with the World's Most Notorious Artist" (2012).
On December 11, 1976, de Hory's live-in bodyguard and companion, Mark Forgy, informed him that the Spanish government had agreed to extradite de Hory to France. Shortly thereafter de Hory took an overdose of sleeping pills, and asked Forgy to accept his decision, not to intervene or prevent him from taking his life. However, Forgy later went for help to take de Hory to a local hospital, though, en route, he died in Forgy's arms. Clifford Irving has expressed doubts about de Hory's death, claiming that he may have faked his own suicide in order to escape extradition, but Forgy has dismissed this theory.
