Editing Marcel Duchamp (section)

===Société Anonyme===
Duchamp created the [[Société Anonyme (art)|Société Anonyme]] in 1920, along with Katherine Dreier and Man Ray. This was the beginning of his lifelong involvement in art dealing and collecting. The group collected modern art works, and arranged modern art exhibitions and lectures throughout the 1930s.

By this time [[Walter Pach]], one of the coordinators of the 1913 Armory Show, sought Duchamp's advice on modern art. Beginning with Société Anonyme, Dreier also depended on Duchamp's counsel in gathering her collection, as did Arensberg. Later [[Peggy Guggenheim]], [[Museum of Modern Art]] directors [[Alfred Barr]] and [[James Johnson Sweeney]] consulted with Duchamp on their modern art collections and shows.
