Dieter Roth (April 21, 1930 - June 5, 1998) was an Icelandicartist of Swiss German origin best known for artist's books and for his sculptures and pictures made with rotting food stuffs. His disdain for the Fluxus group, was as legendary as his unique approach to his art.

His obituary in the New York Times said "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.
