Man Ray was born Emmanuel Radinski, in Philadelphia. In 1915 he met Marcel Duchamp and became involved with the New York Dada group. Man Ray moved to Paris in 1921, where he continued his dada activities and worked as part of the surrealist group. He was able to earn a living as a fashion and portrait photographer, while pursuing creative activities on the side. His artworks took various forms, and included photographs, paintings, objects and collages. A highly inventive photographer, he pioneered several techniques, including 'solarization', invented with his photographic assistant, Lee Miller, who became a photographer in her own right.
