In fine condition. Alexander Calder revolutionized modern art with his ingenious kinetic sculptures and mobiles. Born in 1898, Calder initially trained as a mechanical engineer before embracing his passion for art. His iconic mobiles, characterized by delicately balanced geometric shapes suspended in air, challenged traditional notions of sculpture by introducing movement and dynamism. Inspired by the organic rhythms of nature and influenced by artists like Piet Mondrian and Joan Miró, Calder's creations invite viewers to engage with space and form in playful and unexpected ways. Through his innovative use of simple materials such as wire, wood, and metal, Calder transformed the static into the kinetic, inspiring generations of artists to explore the possibilities of movement in sculpture.
