Alexander Calder

Alexander Calder (1898-1976) was one of the most inventive and influential American artists of the twentieth century, whose invention of the mobile transformed sculpture into a genuinely time-based, kinetic art form. Born in Lawnton, Pennsylvania, into a distinguished artistic family, he was the grandson of the sculptor Alexander Milne Calder and the son of Alexander Stirling Calder, also a prominent sculptor, and his mother was a professional painter. Despite his artistic inheritance, Calder initially pursued a degree in mechanical engineering at the Stevens Institute of Technology, a training that would deeply inform the structural intelligence of his mature work.

After completing his engineering studies, Calder turned to art and enrolled at the Art Students League in New York, where he studied under John Sloan, George Luks, and Guy Pène du Bois. In 1926 he moved to Paris, where he created his celebrated Cirque Calder, a miniature circus of wire figures that he performed for audiences of avant-garde artists including Miró, Léger, and Duchamp. During a 1930 visit to Piet Mondrian's studio, Calder had the revelation that led to his invention of the mobile, sculpture composed of suspended shapes that move freely in the surrounding air. Marcel Duchamp coined the term "mobile" for these works in 1931, and Jean Arp named their stationary counterparts "stabiles."

Calder went on to produce monumental public sculptures installed in cities around the world, alongside paintings, drawings, jewelry, tapestries, and stage sets. His work is held in every major museum, and he remains one of the most beloved and widely recognized figures in twentieth-century art. The lasting importance of Calder's legacy has been reaffirmed by the opening of Calder Gardens in Philadelphia, a new institution devoted to his work along the city's Benjamin Franklin Parkway. Designed by Herzog & de Meuron with landscapes by Piet Oudolf, the site is a fitting tribute in the city where three generations of Calders shaped some of the most beloved public sculpture in America, from Alexander Milne Calder's monumental figure of William Penn atop City Hall to Alexander Stirling Calder's Swann Memorial Fountain nearby, and now to Calder's own work presented in dialogue with them. Together, the three Calders form one of the most remarkable artistic dynasties in American history, and the new gardens ensure that Alexander Calder's contribution continues to be seen at the civic and public scale he always sought.
