Alexander Calder (; July 22, 1898 – November 11, 1976) was an American sculptor known both for his innovative mobiles (kinetic sculptures powered by motors or air currents) that embrace chance in their aesthetic, his static "stabiles", and his monumental public sculptures. Calder preferred not to analyze his work, saying, "Theories may be all very well for the artist himself, but they shouldn't be broadcast to other people." His father, Alexander Stirling Calder, and grandfather, Alexander Milne Calder, were also sculptors.
