Co-founder of ZERO Group Heinz Mack (born March 8, 1931) is a German artist. Together with Otto Piene he founded the ZERO movement in 1957. He exhibited works at documenta in 1964 and 1977 and he represented Germany at the 1970 Venice Biennale. He is best known for his contributions to op art, light art and kinetic art. Heinz Mack was born in 1931 in a small German village. Between 1950 and 1956 he studied at the Kunstakademie Düsseldorf. In 1957 together with Otto Piene he started a series of what were called Abendausstellungen (evening exhibitions) at their studio in Düsseldorf. This series was the initial event for the formation of the group ZERO (with Mack, Piene and Günther Uecker as its nucleus) and the international ZERO movement. Among the participants of the ZERO movement were Yves Klein, Lucio Fontana, Piero Manzoni and Jean Tinguely. In 1964 Mack, Piene and Uecker arranged the "ZERO Lichtraum (Hommage á Lucio Fontana)" at the 1964 documenta in Kassel. From 1964 to 1966 Mack lived and worked in New York where the Howard Wise Gallery presented a solo exhibition in 1966. 1970 Mack was invited as visiting professor to Osaka, Japan. In the same year he represented Germany at the 1970 Venice Biennale (together with Günther Uecker, Georg Karl Pfahler and Thomas Lenk). For the 1972 Summer Olympics in Munich he created an illuminated "Wasserwolke" (Water cloud). In 1972 he was asked to create a 230 ft tall sculpture for the United Nations headquarters in New York (not realized).(https://en.wikipedia.org/wiki/Heinz_Mack) Since 1991 Heinz Mack has turned to painting in pure colors again; the beginning of the "Chromatic Constellations". He understands “color as light and light as color” and seeks to realize his paintings accordingly. For Mack, the intensity of color always correlates with an intensity of light, which spreads like a color space. (http://www.mack-kunst.com/en/Painting.htm) undefined
