Swiss painter and sculptor of German birth. She studied in Basle at the Kunstgewerbeschule from 1929 to 1930. After seeing an exhibition of Bauhaus work, including that of Paul Klee, at the Basle Kunsthalle, Oppenheim produced her first Surrealist work, a series of pen-and-ink drawings in a school notebook. Oppenheim’s earliest works reflect the influence of Klee and the artists of Neue Sachlichkeit. She moved to Paris in 1932 and studied briefly at the Académie de la Grande Chaumière before meeting the Surrealists through Alberto Giacometti and Hans Arp the following year. Creator of the fur-covered cup and saucer: "Le Dejeuner en Fourrure" created in 1936. She was mistress to Man Ray who took beautiful solarized photographs of this dark-haired Frenchwoman. Man Ray posed her nude with an etching press in a celebrated series of photographs that includes Erotique voilée 1933 (Minotaure, 5, 1934, p. 15). She first exhibited with the Surrealists in the Salon des Surindépendants in 1933, then participated in Surrealist meetings and exhibitions until 1937 and again, more sporadically, after World War II. Her participation ended shortly before André Breton’s death in 1966.
