Duchamp-Villon, Raymond, 1876-1918, French sculptor; brother of the artists Marcel Duchamp and Jacques Villon. From the tradition of Rodin he turned to cubism in 1912. He began to assemble machinelike forms with more than a touch of fantasy. His famous geometrically faceted Horse is in the Musée national d'Art moderne, Paris, which contains other of his works. An enlarged cast of the Horse, made after the sculptor's death, is in the Museum of Modern Art, New York City.
