Alexander Calder was an American artist best known for his innovative sculptures, mobiles, and public art installations. He was born on July 22, 1898, in Lawnton, Pennsylvania, USA, and grew up in a family of artists.
Calder attended the Stevens Institute of Technology and the Art Students League in New York City before studying in Paris in the 1920s. It was there that he developed his signature style of kinetic art, which he called "mobiles." These sculptures, made of delicate metal shapes and suspended on wires, were designed to move and interact with their environment through the slightest air currents.
In addition to his mobiles, Calder also created a series of large-scale public sculptures, including his famous "Flamingo" in Chicago's Federal Plaza. Throughout his career, Calder was recognized as one of the leading figures in modern art, and his work has been exhibited in museums and galleries around the world. He died on November 11, 1976, in New York City.
