Alexander Calder (1898-1976) was an American artist best known for his invention of the mobile, a type of kinetic sculpture made with delicately balanced, suspended shapes that move in response to air currents. Calder was interested in a wide range of artistic movements and techniques, including abstract art, Surrealism, and Constructivism. Calder's interest in geometry is evident in his work and he often used geometric shapes such as circles, triangles, and rectangles as the basis for his compositions. His use of these shapes was influenced by his interest in the principles of sacred geometry. This philosophy influenced his approach to art and helped him create works that were both visually striking and emotionally resonant.
