The Armory Show of 1913, officially known as the International Exhibition of Modern Art, is credited with introducing modern art to the U.S..
Held in New York City at the 69th Regiment Armory, the gigantic exhibition of about 1,600 works presented much that Americans found new, controversial, and ultimately influential.
Contemporary artists represented in the show included Frenchman Marcel Duchamp and Russian Wassily Kandinsky.
