Zero is a group of artists founded by "Heinz Mack and "Otto Piene and the name of their magazine. The word “zero” expressed, in Piene’s words, “a zone of silence and of pure possibilities for a new beginning.” The movement is commonly interpreted as reaction to "Abstract Expressionism by arguing that art should be void of color, emotion and individual expression.
Zero was the name of a magazine published in 1958 by "Heinz Mack and "Otto Piene. The magazine was published in association with the shows, such as Zero 1 (1958), Zero 2 (1958), and Zero 3 (1961). The magazine included texts in multiple languages written by artists and curators active in the Zero circle who sought to define what they termed The New Artistic Conception. The involved artists soon established a vigorous network of collaboration and exchange.
Like-minded practitioners came above all from France ("Arman, "Jean Tinguely and "Yves Klein), Italy ("Lucio Fontana, "Piero Manzoni, Belgium ("Pol Bury), and Switzerland (Christian Megert). In the Netherlands, the “informal group” of Nul (Dutch for 'zero') artists began around 1958 and can be narrowed to four: Jan Schoonhoven, "Armando, Jan Henderikse and "Henk Peeters, who were linked to the Italian and German painters but penned their own manifesto. Latin American artists, like the Venezuelan "Jesús Rafael Soto, and Brazilian Almir Mavignier became affiliated with Zero while working in Paris in the 1950s.
Mack and Piene invited artists like "Günther Uecker to exhibit in their studio, and the three friends became the founding fathers of the ZERO movement, which would soon reach out to embrace artists throughout Europe. Working in an environment without galleries and contemporary art spaces, these artists came together to exhibit their work in a series of one-day-only evening exhibitions, often staged in their studios.
In 2008, Piene, Mack, Uecker, and "Mattijs Visser created the international ZERO foundation.. The foundation initiated and organized ZERO exhibitions at the Guggenheim Museum in New York, The Martin Gropiusbau in Berlin, the Stedelijk Museum in Amsterdam, and exhibitions with the three founders in Moscow, Istanbul, Hannover, Düren.
1959 - First real ZERO exhibition
Artists Pol Bury, Paul van Hoeydonck, Jean Tinguely, and Daniel Spoerri organized "Motion in Vision – Vision in Motion", an exhibition at Hessenhuis in Antwerpen that for the first time gave ZERO an international audience. Following Otto Piene this exhibition was the first real ZERO exhibition, after the exhibitions held at the studio from Heinz Mack and Otto Piene in 1957.
1962 - First international museum exhibition by ZERO
Already in the early sixties the artist Henk Peeters presented the international director of the Stedelijk Museum Amsterdam, Willem Sandberg, with monochromatic works of the young European artists' generation. In close exchange with Heinz Mack, Otto Piene and Günther Uecker as well as Yves Klein and Piero Manzoni the original concept was further developed. This was the result of an exhibition which, besides monochromy, also concerned itself with colour, vibration, light and movement. There were works by European artists, works from North and South America as well as from Japan. The exhibition was initiated, organized and financed by the artists themselves. The selection of the participants took place likewise by the artists, a curatorial direction according to our present understanding there was not. The exhibition was accompanied by a jointly developed catalogue.
1993-1999 - Country-specific exhibition series on the ZERO movement
Between 1993 and 1999, four ZERO exhibitions took place at Galerie Villa Merkel in Esslingen, curated by art historian Renate Wiehager. The exhibition series, which is specific to the NUL Group from the Netherlands, ZERO Italy and ZERO Paris, ended in 1999 with the exhibition Zero Deutschland 1960. And today. Apart from the three protagonists of the German ZERO movement, she devoted herself to a further twenty artists whose works ranged from the late 1950s to the 1990s. Unlike in the 1960s, this series of exhibitions was not initiated, organized and financed by the artists. This series of publications was accompanied by four publications with a first comprehensive overview of ZERO as a European movement in four languages: German, English, Dutch and French.
2006 - First overview exhibition of the international ZERO movement
The Museum Kunstpalast in Düsseldorf presented the first overview exhibition of the international ZERO avant-garde in 2006.

Heinz Mack, Otto Piene and Günther Uecker curated their own areas. Henk Peeters, who had organized the historical ZERO exhibitions in 1962 and 1965 at the Stedelijk Museum Amsterdam, consulted in the field of design, selection of artists and works. The Düsseldorf exhibition covered several aspects of the exhibitions from the Stedelijk Museum Amsterdam in the form of reconstructions of former installations.

The works were loaned by the German collectors Gerhard and Anna Lenz, a German couple that was involved with the Zero movement almost from its beginnings. Gerhard Lenz had first encountered the Zero group at an exhibition of Piene’s work in a Düsseldorf bookshop more in 1963. From 1974, the couple exhibited the collection in 12 shows over 25 years, including in Frankfurt, Barcelona, Moscow, and Warsaw.

2015 - The most comprehensive international ZERO exhibition in Berlin
The exhibition, opened in March 2015 at the Martin-Gropius-Bau Berlin, was conceived and organized jointly by artists and experts in the tradition of the ZERO movement. Various subjects - articulated in time, space, color, reflection, vibration, light and movement - showed works of art from the central years of the ZERO movement from 1957 to 1967. With around 40 artists, the exhibition followed the ZERO spirit, from two-dimensional paintings to the three-dimensional space. On a total of 3,000 square meters, artists from Germany, Italy, France, Belgium, the Netherlands, Venezuela, Switzerland, Japan, the USA and Brazil were represented with around 200 works and ten space-filling installations. Among them were some rare works from renowned collections such as the Georges Pompidou Center, the Morsbroich Museum, the Stedelijk Museum in Amsterdam and the Museum of Fine Arts in Düsseldorf. In addition, for the first time, works by several artists were shown: Manzoni, Verheyen, Fontana, Tinguely, Klein, Mack and Piene. The highlight of the collaboration was the space-saving historical installation Lichtraum (Hommage à Fontana) by Mack, Piene and Uecker, which was presented for the first time at the documenta III 1964. Heinz Mack presented an installation as han omage to his already deceased ZERO friends. In the form of a ZERO chronology, the most important exhibitions and events were documented using previously unpublished photo and video material. In addition, the works that had previously been lost in the course of the preparation of the exhibition were still to be seen in this exhibition.

Interest in Zero artists has seen an extraordinary resurgence in recent years, with works from European painters of the period achieving records at auction. In 2010, "Sotheby's auctioned off parts the collection of Gerhard and Anna Lenz in London. Initially valued at 12 million pounds ($19.5 million), the 49 paintings, drawings and low-relief panels made up from a variety of media were sold in an evening auction reaching £54.07 million, or about $84.5 million; unusual for a contemporary art sale, 74 of the 77 lots offered sold, resulting in a 96 percent success rate.
