The International Exhibition of Modern Art, quickly known as the Armory Show, opened at New York's 69th Regiment Armory on February 17, 1913. Organized by the Association of American Painters and Sculptors, it brought roughly 1,300 paintings, sculptures, and decorative works by more than 300 European and American artists before a public used to academic realism. Its galleries included Impressionist, Fauvist, and Cubist work, with loans by artists such as Marcel Duchamp, Henri Matisse, Pablo Picasso, Paul Cezanne, Wassily Kandinsky, Claude Monet, Vincent van Gogh, Mary Cassatt, Edward Hopper, George Bellows, and James McNeill Whistler. The show's controversy, especially around Duchamp's Nude Descending a Staircase, No. 2, made modernism a mass-media subject in the United States.
It became the canonical starting point for modern art's broad public reception in the United States.
