Sculptor and kinetic artist Alexander Calder was born in 1898 in Lawnton, Pennsylvania. As the son of two artists, he was encouraged to sculpt and construct things in his own workshop at an early age. In 1919 he graduated from Stevens Institute of Technology with a degree in mechanical engineering, and after holding several jobs, he decided to take classes at the Art Students League in New York City. He began exhibiting his paintings, but also focused on drawing, illustration, and wood and wire sculpture. In 1926 Calder moved to Paris and began making toys for his performance piece, "Cirque Calder." He married Louisa James in 1931 and exhibited his mobiles for the first time the same year. He continued to spend his time between New York and Paris, and he and Louisa also bought a farm in Roxbury, Connecticut. They had two children, Sandra and Mary. Calder befriended many influential artists, including Joan Mirò, Fernand Léger, Marcel Duchamp, and Yves Tanguy, and joined the Abstraction-Création group in 1931. He exhibited and worked on commissions extensively throughout his career. As a very prolific artist, he had alliances with several galleries, including the Pierre Matisse Gallery in New York. Later in his career, Calder began focusing on large-scale outdoor sculptures. He died in 1976 at the age of 78.
