Associated with the Dada, Surrealist, Cubist, and Futurist movements, Marcel Duchamp radically subverted conventional practices of artmaking and display, challenging such weighty notions as the hand of the artist and the sanctity of the art object. Duchamp’s depiction of dynamic Cubist forms in Nude Descending a Staircase No. 2 (1912) established him as a leading member of the international avant-garde. In 1913 Duchamp created Bicycle Wheel, which is considered the first of his famous readymades—minimally altered objects that are elevated to the status of art simply through the designation of the artist. Particularly in his readymades, Duchamp placed unprecedented emphasis on the artistic concept as paramount over craftsmanship or aesthetics, a guiding principle that has proved hugely influential to 20th-century artistic practice.
A taste for jokes, tongue-in-cheek wit and subversive humor, rife with sexual innuendoes, characterizes Duchamp's work and makes for much of its enjoyment. He fashioned puns out of everyday expressions which he conveyed through visual means. The linguistic dimension of his work in particular paved the way for Conceptual art.
