Auction introduction: A leading figure in 20th-century art, Denise René was a pioneer of kinetic art and geometric abstraction. When she founded her Paris gallery in 1944, it became a true centre of experimentation, a space where innovation thrived and artists such as Vasarely and Julio Le Parc first captured the public’s imagination. More than a gallerist, Denise René was a visionary patron, guided by the belief that art should be both rigorous and alive, in constant motion. The sale of works from the Galerie Denise René pays tribute to her enduring influence and to a lifetime devoted to discovery, precision, and creative freedom. Each work offered reflects the spirit of inquiry and boldness that defined her contribution to the history of modern art.
