Alexander Calder was an American sculptor who is best known for his innovative mobiles (kinetic sculptures powered by motors or air currents) that embrace chance in their aesthetic and also for his monumental public sculptures. Known primarily for his sculpture, Calder also created paintings and prints.

Alexander Calder's work is in many permanent collections, most notably in the Whitney Museum of American Art, but also the Guggenheim Museum, the Museum of Modern Art and the National Gallery of Art, Washington, DC.
