Dieter Roth (April 21, 1930 – June 5, 1998) was a Swiss artist best known for his artist's books, editioned prints, sculptures, and works made of found materials, including rotting food stuffs. He was also known as Dieter Rot and Diter Rot.
The dark undertone and furious, obsessive energy of his work ultimately separated him from many of the more lighthearted Fluxus artists. Perhaps despite himself, he was a fluent draftsman and expert printmaker, and his drawings and prints contained his wild energy within peculiarly virtuosic forms. Compared to the innumerable self-described artists of the last several decades who faked their way through his sort of work, Mr. Roth was the genuine item.
