Published to accompany an exhibition at the Martin-Gropius-Bau in Berlin, the result of a collaborative research project that also produced a comprehensive exhibition at the Solomon R. Guggenheim Museum in New York and an upcoming show at the Stedelijk Museum in Amsterdam, ZERO brings together the work of 45 artists from the ZERO network more than 50 years after the founding of the movement. Devoted not only to the first founding artists--Heinz Mack, Otto Piene and Günther Uecker--nor even just to those international artists associated with the network like Yves Klein and Lucio Fontana, this volume also seeks to document the contributions of lesser-known artists such as Hermann Goepfert, Oskar Holweck and Hans Salentin. Organized by the ZERO foundation and including some 200 objects, ZERO is one of the most comprehensive resources available on this self-consciously avant-gardist international movement.
