Abstract Geometric Shapes on Yellow Ground

Alexander Calder (1898–1976) was an American artist renowned for revolutionizing sculpture through his invention of the mobile—kinetic sculptures that move with air currents—and the stabile, his term for static abstract works. Calder’s practice spanned a wide range of media, including wire sculpture, painting, jewelry, and monumental public commissions. His distinctive style is characterized by bold primary colors, organic forms, and a playful sense of movement, reflecting his background in engineering and his fascination with balance and motion.

Calder’s work has been the subject of major institutional exhibitions worldwide, including retrospectives at the Museum of Modern Art (MoMA) in New York, the Solomon R. Guggenheim Museum, and the Centre Pompidou in Paris. His sculptures are held in the permanent collections of leading museums such as the Whitney Museum of American Art and the Tate Modern. Calder’s market presence remains robust, with his works regularly achieving significant results at major auction houses. Notably, his mobile "Poisson volant (Flying Fish)" sold for over $25 million at Christie’s in 2014, and his monumental stabiles and mobiles consistently command high prices at Sotheby’s and Bonhams, underscoring his enduring influence and desirability among collectors. Born in Lawnton, Pennsylvania, Calder’s innovative vision continues to shape the trajectory of modern and contemporary sculpture.
