Julio Le Parc (Mendoza, Argentina, 1928 – Paris, 2026) was a central figure of kinetic and optical art. He studied at the Escuela de Bellas Artes in Buenos Aires and settled in Paris in 1958 on a French government scholarship.

From 1959 he painted geometric abstractions based on predetermined systems, then moved on to reliefs, continuous mobiles and works with light and movement. He invited the public to take part through mazes and game rooms.

He co-founded the Groupe de Recherche d’Art Visuel and won the grand prize for painting at the Venice Biennale (1966), the year of his first solo show in New York. His work is presented at Galería Duque Arango.
