Early in his painting career Marcel Duchamp explored cubism with an emphasis on successive images of a single body in motion, leading to works such as Nude Descending a Staircase . In 1913, Duchamp abandoned traditional painting and drawing techniques, creating The Bride Stripped Bare by Her Bachelors, which incorporated mechanical drawings and nota- tions. He also began to experiment with Readymades in 1914. After associating with the Dada group in Paris, he made his first motor-driven construction. In 1923, Duchamp seemingly abandoned his interest in art for chess, though he still continued to experiment and collabo- rate with the Surrealists. Duchamp settled permanently in New York in 1942, associating with Surrealist émigrés. In 1946 he secretly began work on a major assemblage that would last the next 20 years [Etant Donnée]. He died on October 2, 1968.
