Alexander Calder (1898-1976) was an American artist known for his mobiles and suspended sculptures. Born in Lawton, Pennsylvania, he had an early interest in movable objects and received an engineering degree from the Stevens Institute of Technology in Hoboken, New Jersey. He later turned to art in the 1920s and attended the Arts Students League in New York. He continued his studies in Pairs, where he began creating large-scale mechanical installations of intricate circus scenes. He later sculpted portraits and figures and incorporated abstract, kinetic elements into his sculptures, creating the Mobiles he is best known for. He constructed his sculptures out of wire, metal, and wood, blending abstract and surrealistic forms with biomorphic imagery.
