Alexander Calder was an American sculptor best known as the originator of the mobile, a type of kinetic sculpture the delicately balanced or suspended components of which move in response to motor power or air currents; by contrast, Calder’s stationary sculptures are called stabiles. He also produced numerous wire figures, notably for a vast miniature circus.
