Surrounded by an artistic family, Alexander Calder builds, from a young age, his very first objects, fascinated by movement and mechanism. In 1923, he decides to study art in New York before settling in Paris, in 1926, where he begins to imagine fantasy figures made of wire, cork and textile. Alexander Calder thus sets the Calder Circus up, a show that earns him a certain recognition from Paris’ artistic circles for whom he creates three-dimensional animals and portraits for such individuals as Fernand Léger or Kiki de Montparnasse. When he discovers Piet Mondrian’s work, in 1930, he decides to follow the abstract movement and builds moving and rotative sculptures made of spirales, arches and spheres held by long metallic stems, hence launching an atmosphere that clearly evokes that of the cosmos and that Marcel Duchamp will entitle Mobiles. The artist also conceives their opposites: heavy, earthy and gigantic sculptures, the Stabiles that take place within urban environments, in Paris’ La Défense or at Montréal’s Universal Exposition, in 1967. But aside from this youthful, adventurous and bizarre world he established, Alexander Calder remained a down-to-earth man who appreciated nothing more than to cultivate organic vegetables in his farm.
