Alexander Calder , the son and grandson of sculptors, first trained as an engineer at the Stevens Institute of Technology. He was self-taught as a sculptor. Exposure to the works of Joan Miro and the Surrealists in Paris in the late 1920s and early 1930s provided a liberating influence. From toy-like wire figures he evolved a style of suspended, wind driven abstract forms which he called "mobiles." kentuckycenter.org
Although its four profiled planes stand firmly perpendicular to the ground, the illusion of motion pervades all of Calder's work. www.kentuckycenter.org/aboutus/redfeather.asp
