Man Ray

In 1915, Man Ray met French artist Marcel Duchamp, and together they collaborated on many inventions and formed the New York group of Dada artists. In 1921, Ray moved to Paris and became associated with the Parisian Dada and Surrealist circles of artists and writers. His experiments with photography included rediscovering how to make "camera-less" pictures, which he called rayographs.
