Dieter Roth (1930, Hannover – 1998, Basel) was a Swiss artist best known for his artist's books, editioned prints, sculptures, and works made of found materials. During the 1960s, Roth participated in happenings and Fluxus events. He created art objects from organic material that underwent a process of gradual change and decay, including airtight spice, mold, and chocolate objects. Together with Daniel Spoerri and André Thomkins, he produced works of Eat-Art. In the 1970s, he designed a variety of book objects in terms of content and graphics, which are close to the Dadaist work of Kurt Schwitters.
