Alexander Calder was an influential American sculptor best known for his innovative works in kinetic art and mobile sculptures. Born on July 22, 1898, in Lawnton, Pennsylvania, Calder came from a family of artists—his mother was a painter, and his father and grandfather were sculptors. He studied at the Stevens Institute of Technology and later at the Art Students League in New York.

Calder initially gained recognition for his wire sculptures, which captured the fluidity of form and movement. He is best known for creating mobiles, a type of sculpture that moves with air currents. His works often blend abstract shapes and vibrant colors, engaging viewers in a dynamic visual experience. Notable artworks include “Lobster Trap and Fish Tail” (1939), which exemplifies his signature style; “Bacchanale” (1945), a large mobile that dances in the air; “La Grand Vitesse” (1969), a monumental public sculpture in Grand Rapids, Michigan; and “Flamingo” (1974), a striking red structure located in Chicago’s Federal Plaza.

Throughout his career, Calder sought to create art that was accessible and interactive. His innovative approach to sculpture has left a lasting impact on modern art, and he is celebrated as one of the pioneers of kinetic and mobile sculpture. Calder passed away on November 11, 1976, but his playful, imaginative works continue to captivate audiences around the world.
