Heinz Mack attended grammar school in Gießen and received piano lessons as a child. He studied at the Düsseldorf Art Academy from 1950 to 1953 and passed his state examination in art and crafts education. From 1953 to 1956, Mack also studied philosophy at the University of Cologne. He earned his living as a student councillor. His first solo exhibition took place in 1957 at the Schmela Gallery in Düsseldorf. Together with his friend and colleague Otto Piene (1928−2014), Mack organised a series of so-called "evening exhibitions" from 1957, which took place in Otto Piene's studio at Gladbacher Straße 69 in Düsseldorf. The term "ZERO", which is also used as the title for the three issues of their magazine published in Düsseldorf, was first used in this context in 1958. The artists of the ZERO movement repeatedly included the streets and public spaces in their actions they called "demonstrations". On the occasion of the publication of the magazine "ZERO 3" on 5th July 1961, they organised a "ZERO Festival" in front of the Schmela Gallery in Düsseldorf. On 17th May 1962, Heinz Mack, Otto Piene and Günther Uecker held a "ZERO Demonstration" at the Rheinwiesen in Düsseldorf, and in February 1964 they took part in the procession on Rosenmontag (carnival Monday) with a "ZERO Running Car". In 1959 Mack wrote the so-called "Sahara Project" and from 1962 installed the "Jardin artificiel" several times in the deserts of Africa. In 1968 he made the award-winning film "Tele-Mack", in which the artist explored and documented the energy and power of light. Between 1964 and 1966 Mack lived mainly in New York. In 1970 he was a visiting professor at Osaka University of Arts. He is represented in numerous exhibitions at home and abroad, including documenta 2 (1959), 3 (1964), 4 (1968) and 6 (1977), as well as the 35th Venice Biennale (1970) and subsequent exhibitions: "Festival d'art d'avantgarde", Grand Palais, Paris (1960), "Nove tendencije" 1 and 2, Galerija suvremene umjetnosti, Zagreb (1961, 1963), "Nul", Stedelijk Museum, Amsterdam (1962), "Zero Demonstration", Institute of Contemporary Arts, London (1964), "Licht und Bewegung", among others at Kunsthalle Bern (1965), "The Responsive Eye", The Museum of Modern Art, New York (1965), World Exhibition in Montreal (1967) and in Osaka (1970), "Prospect: Retrospect.
