The celebrated, full-scale life of the century's most influential artist. One of the giants of the twentieth century, Marcel Duchamp changed the course of modern art. Visual arts, music, dance, performance--nothing was ever the same again because he had shifted art's focus from the retinal to the mental. Duchamp sidestepped the banal and sentimental to find the relationship between symbol and object and to unearth the concepts underlying art itself. The author's intimacy with the subject and glorious prose style, wit, and deep sense of irony--"the only antidote to despair"--make him the perfect writer to bring this stunning life story to intelligent readers everywhere.
