The New York presentation of the International Exhibition of Modern Art, later known as the Armory Show, ended its run at the 69th Regiment Armory on March 15, 1913. Organized by the Association of American Painters and Sculptors, the exhibition brought roughly 1,300 works by more than 300 European and American artists before a large U.S. public. Its New York installation made works by Marcel Duchamp, Henri Matisse, Paul Cezanne, Pablo Picasso, Constantin Brancusi, and other avant-garde figures a matter of public controversy rather than specialist debate. After March 15, the show moved to the Art Institute of Chicago and then to Boston, extending the shock waves beyond New York.
It accelerated American engagement with Cubism, Fauvism, and modernist collecting.
