Alexander Calder (1898 – 1976) was a monumental artist whose invention of the mobile tremendously influenced the art world. Mobiles are airy, hanging structures connected by wires and set in motion by the wind. Calder’s versions simply yet profoundly celebrated form and color, and the joy of creating both. A trained engineer, he became a freelance artist after attending New York’s Art Students League. Calder was strongly inspired by the spectacle and wonder of the circus, constructing entertaining mobiles often accompanied by music. Producing dynamic yet playful mobile sculptures, Calder dismissed the formal structures of art and redefined its infinite possibilities.
