Alexander Calder

Alexander Calder (American, born 1898) revolutionised sculpture by introducing movement as a core artistic element, most famously through his mobiles—balanced forms animated by air currents. He also created monumental, static outdoor works called stabiles, alongside drawings, jewellery, and stage designs. Calder’s art combines engineering-like clarity with playful abstraction, turning balance, rhythm, and chance into visual poetry. His innovations helped open modern sculpture to time, motion, and viewer interaction.
