Calder is one of the most acclaimed and influential sculptors of the 20th century. He is renowned for the invention of the mobile, kinetic construction of suspended abstract elements that describe individual movements. He also produced numerous wire figures, notably for a miniature circus. In addition to sculptures, Calder painted throughout his career, beginning in the early 1920s. He picked up his study of printmaking after moving to Paris in 1926 and continued to produce illustrations for books and journals.
