Alexander Calder is the subject of a small exhibition each year at the MCA to provide an opportunity to look at how the seminal artist's ideas developed throughout his fifty-year career. These works from 1927 to 1968, mostly from The Ruth and Leonard Horwich Family Loan, include examples of Calder's mobiles, stabiles, drawings, and paintings. Calder combined colorful shapes abstracted from nature -- snowflakes, birds, and animals -- with an interest in mechanics to create whimsical, hanging mobiles that move with air currents. His explorations of both geometric and organic shapes have distinguished him as an innovator of art that responds to its physical environment. Calder changed his focus from drawing to painting to eventually creating stabiles, mobiles, and large-scale sculptures. Upon his return to the United States, Calder's work turned towards natural forms that he simplified into dynamic, often whimsical creatures. This exhibition is organized by Pamela Alper Associate Curator Julie Rodrigues Widholm.
