Julio Le Parc (1928–2026) was an Argentine artist and a pioneering figure in optical and kinetic art. Born in Palmira, Mendoza, he studied in Buenos Aires before moving to Paris in 1958. A founding member of the Groupe de Recherche d’Art Visuel (GRAV), he explored light, movement, color and the active participation of the viewer. His practice encompassed geometric painting, sculpture and immersive installations that challenge visual perception. He received the Grand Prize for Painting at the Venice Biennale in 1966.
