Alexander Calder

(Philadelphia, USA, 1898 – New York, USA, 1976)

He first studied engineering, then, from 1922, he studied art. In 1926 he moved to Paris and began to make wire sculptures, realising the value of space enclosed by lines as a suggestion of mass. In 1931 he joined the Abstraction Creation Group and began to produce within that trend. Shortly after he began to construct mobile sculptures using motors, which he later replaced by others driven exclusively by the unstable balances that determine mobility as a whole, either by air impulse or by giving them a small initial thrust. In 1952 he won the Grand Prize for Sculpture at the Venice Biennale.
