Crossing countries and continents, Dada was one of the most influential avant-garde art movements of the 20th century. Growing out of New York and neutral Zurich, the movement spread rapidly to Berlin, Cologne, Hanover, Paris and beyond in response to the disasters of WWI and the emerging media and machine culture. Members of a caustic, critical, creative revolution, Dada artists worked with innovative art-making strategies such as collage, montage, assemblage, and "ready-made" sculpture, in an effort to subvert and challenge modernity itself. Premiering at the National Gallery of Art, this major museum exhibition is the first in the United States to focus exclusively on the movement. Surveying the diverse artistic production as developed in the movement's six primary centers, the show canvases the Dada incredibly creative fervor by showcasing over 400 works, from films, paintings and photography to sound recordings and three-dimensional objects. Among the nearly 50 artists represented are such heavyweights as Hans Arp, Marcel Duchamp, Max Ernst, Kurt Schwitters and Raol Hausmann.
