ZERO was officially established by Heinz Mack and Otto Piene in the city of Düsseldorf in 1958. Its prelude had taken place the previous year with the first evening exhibit in Otto Piene’s studio located on Gladbacher Strasse in Düsseldorf. Günther Uecker became the artistic union’s third member in 1961.
Especially during 1957 to 1966, the activities of Günther Uecker, Otto Piene, and Heinz Mack touched a nerve for the period in a fascinating way. The artists, whose works range from painting to sculpture to actions, united the effort to develop a new language of forms in which light and movement are the essential elements. New types of materials, notions of space and light sensations found their way into the visual arts, which then advanced to the concept of room installation art. The international connections that were facilitated and created by ZERO became important; this is how its path to the center of the art world was cleared.
