Mobiles and their beginnings. Where did it all start? Hanging, dangling pieces of metal, wood and plastic? Mobiles have been around since the early 1900's when Russian Constructivist Alexander Rodchenko appropriated the idea of the hanging mobile. From this idea, Alexander Calder (1898-1976) was the first to develop the mobile as a three-dimensional kinetic art form. In 1932 Marcel Duchamp gave the name "mobiles" to Alexander Calder 's new art forms. Calder also made static, sculptural constructions called "stabiles", this term was titled by Jean Arp.
