Haacke, Hans (1936-). German *Conceptual and experimental artist, active mainly in the USA. He was born in Cologne, studied in Kassel, and first went to the USA on a Fulbright travelling scholarship in 1961, since when he has taught and exhibited widely there, living mainly in New York. His early work was much concerned with movement, light, and the reaction of objects with their environment. In the early 1960s, for example, he began making constructions in which fluids are enclosed in plastic containers in such a way that they can be seen responding to changes in temperature, etc. Wind and water have played a large role in his work and he participated in the '*Air Art' exhibition that toured the USA in 1968. From about the mid-1960s, however, he became more interested in spectator participation, the social function of art, and ecological issues. Haacke's work has often caused controvery because of his preoccupation with 'exposing systems of power and influence. His Real Time Social System of 1971 featured photographs of a large group of New York slum buildings, all owned by one firm, while captions revealed an array of holding companies, mortgage data, assessed values and property taxes. When the * Guggenheim Museum cancelled his exhibition there rather than show this work, Haacke did one which traced the various family and business ties between the Guggenheim trustees' ( Roberta Smith, "'Conceptual Art'" in Nikos Stangos, ed., Concepts of Modern Art, revised edn., 1981).
