Alexander Calder

Alexander Calder was an American sculptor known both for his innovative mobiles that embrace chance in their aesthetic, and static "stabiles" monumental public sculptures. Calder preferred not to analyze his work, saying, "Theories may be all very well for the artist himself, but they shouldn't be broadcast to other people."Born into a family of artists, Calder's work first gained attention in Paris in the 1920s and was soon championed by the Museum of Modern Art in New York, resulting in a retrospective exhibition in 1943. Major retrospectives were also held at the Solomon R. Guggenheim Museum and the Museum of Contemporary Art, Chicago.

Calder's work is in many permanent collections, including the Whitney Museum of American Art, the Guggenheim Museum, the Museum of Modern Art, the National Gallery of Art in Washington, D.C., and the Centre Georges Pompidou in Paris. He produced many large public works, including .125, Pittsburgh Spirale, Flamingo and Universe, and Mountains and Clouds.
