Alexander Calder (1898–1976) was an American sculptor renowned for inventing the mobile and stabile—kinetic and stationary abstract forms constructed from sheet metal, wire, bolts, and paint. His practice evolved from early experiments with wood and wire constructions in the 1930s to monumental steel sculptures that engaged architecture and landscape. Calder's work oscillates between delicate, balanced suspended forms and earthbound stabiles with jagged, biomorphic silhouettes. His abstract vocabulary—organic curves, intersecting planes, primary colors—references natural forms without representing them literally. Born into a family of Philadelphia sculptors, Calder spent his career bridging European modernism and American innovation, creating works that activate space through both stillness and motion.
