Accession Number

Alexander Calder harnessed one of nature’s fundamental forces—gravity—to create his kinetic, yet balanced “drawings in space.” With a mechanical engineering degree, Calder understood the physics of objects’ movements. This knowledge sparked his invention of the moving sculpture, termed the “mobile” by Marcel Duchamp. The mobiles are comprised of colorful pieces of sheet metal, delicately dangling on monofilament. The sculptures’ oscillation constantly transforms the viewers’ experience of the work.
