Philadelphia Museum of Art. Dreier returned to London to marry Edward Trumball in August 1911, but was back in England by September, and her marriage was annulled. There she saw
Marcel Duchamp's
Nude Descending a Staircase, which was considered the "controversial centerpiece of the show." She was frustrated by the lack of respect given to the new, emerging artform. Wassily Kandinsky and Duchamp both influenced her work, which is realized in the
Abstract Portrait of Marcel Duchamp that she made in 1918, Dreier, Duchamp and
Dadaist and
Surrealist Man Ray founded the
Société Anonyme in 1920 for "the study and promotion of modern art," including
Cubism,
Expressionism,
Dadaism,
Futurism, and
Bauhaus art. Katherine Dreier deeply resented the upstart rival
Museum of Modern Art, whose wealthy backers, she felt, had stolen her mission and her ideas and even her name—the Société Anonyme's subtitle was "Museum of Modern Art." In truth however, Dreier's tireless idealism could not make up for her lack of significant financial support. The Société Anonyme's exhibition rooms were too small, but Dreier's attempts to find larger quarters kept breaking down because the funds, which came mainly from her and her two sisters, were insufficient. Her society—as time went on it became more and more a one-woman operation—could and did claim precedence, nevertheless, as the first museum anywhere in the world that was devoted exclusively to modern art. She wrote the book
Western Art in the New Era about modern art, which was published in 1923
The Cooperative Mural Workshop, The Society of Independent Artists, and The Société Anonyme Dreier created the Cooperative Mural Workshop in 1914 following the derisive response to the Armory Show. She described the workshop as something that "United art and artisanship and brought about usefulness and beauty." The society sponsored lectures, concerts, publications, and exhibitions of modern art. Duchamp and Dreier presented the Société Anonyme's art collection to Yale University in 1941. She gave a Trowbridge Lecture on the "Intrinsic Significance of Modern Art" in 1948 at
Yale University. In 1950 Duchamp and Dreier published a catalog of the Société Anonyme's works donated to Yale. The organization ended on its 30th anniversary in 1950, when the three founders formally dissolved it. ==Later years and death==
