Nude Descending a Staircase (No.2)/Nu descendant un Escalier. No.2. 1912. Oil on canvas 147.5 x 89 cm. The Philadelphia Museum of Art, Philadelphia, PA, USA. Inspired by the photographic motion studies of Eadweard Muybridge (left), Nude Descending a Staircase, No. 2, was painted by Duchamp in 1912. When it was first exhibited at the legendary Armory Show in New York (February 17-March 15, 1913), it caused an uproar which both outraged many people and made Duchamp famous in America. One critic called it “an explosion in a shingle factory.”
