Elmyr de Hory was a famed Hungarian-born painter and art forger. It is claimed he was responsible for producing over a thousand forgeries that were sold to reputable art galleries all over the world. His activities garnered celebrity from a Clifford Irving book, Fake (1969), and a documentary essay film by Orson Welles, F for Fake (1974).

Art forgery is the creation and sale of works of art which are falsely credited to other, usually more famous artists. Art forgery can be extremely lucrative, but modern dating and analysis techniques have made the identification of forged artwork much simpler.
