Happy Birthday Alexander Calder! American, born in 1898, Calder was initially an engineer. His father was a sculptor. Alexander invented Stabiles and Mobiles which is the union of engineering and sculpture. He is probably best known for his mobiles and kinetic sculpture works. The airy movement and counterbalance of his projects added charm and whimsy to the sculpture scene. The work is wire and metal; the lines and shapes combine to remind one of Miro. The mobile below is Lobster Trap and Fish Tail.
