Zero was founded in Dusseldorf in 1957-58 by Heinz Mack and Otto Piene (Günther Uecker joined in 1961) as a deliberate zero hour after the subjective gestures of Art Informel and Abstract Expressionism. Through its magazine, editions, and an international exhibition network reaching from Europe to Japan and the United States, Zero proposed art of light, movement, and monochrome - white fields that let illumination do the painting, nail reliefs that catch and scatter light, and smoke-and-fire paintings made with actual flame. The group dissolved in 1966, but its core moves - light as material, texture as event, color stripped away to let phenomena through - fed directly into kinetic art, the Light and Space movement, and contemporary experiential installation.
