Alexander Calder

Alexander Calder (1898 – 1976) 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 his monumental public sculptures. Although primarily known for his sculpture, Calder also created paintings and prints, miniatures (such as his famous Cirque Calder), theater set design, jewelry design, tapestries and rugs, and political posters.
