Société Anonyme, Inc. was an art organization founded in 1920 by Katherine Dreier, Man Ray and Marcel Duchamp. The society sponsored lectures, concerts, publications, and exhibitions of modern art, including the International Exhibition of Modern Art at the Brooklyn Museum in 1926. Between 1920 and 1940 they held 80 exhibitions showing mostly abstract art.
Man Ray picked the name "Société Anonyme", having seen it in French magazines, but knowing little French, assumed it referred to some anonymous society. It actually means "Corporation", but Duchamp thought it a fine name and later while the legal paper work was being written up the "Inc." was added, making its English translation being: "Corporation, Inc.".
