"I wanted to make something that could move and that would be a bit unpredictable and would bring something of the outside into the room."

Alexander Calder (1898–1976) was an American sculptor known for his pioneering work in kinetic art and the creation of mobiles. Born in Lawnton, Pennsylvania, Calder initially studied mechanical engineering before shifting to art. He moved to Paris in 1923, where he developed his distinctive style of abstract, moving sculptures.

Calder's notable works include "Lobster Trap and Fish Tail" (1939) and "Calder’s Circus" (1926), reflecting his innovative approach to combining art and movement. His first major solo exhibition was at the Museum of Modern Art in New York in 1932. Calder's sculptures, including mobiles and stabiles, have been celebrated for their dynamic and imaginative qualities.

He passed away on November 11, 1976, in New York City, leaving a lasting impact on modern art through his revolutionary contributions to sculpture.
