The resulting artworks (such as his project for the Reichstag in Berlin, Der Bevolkerung [To The Population, 1999]) have often drawn immense controversy. Haacke is a unique figure in post-war art, and his work has touched on such diverse movements as Conceptual, Pop, Minimal and Land art. His integrity as well as the formal innovations of his art have proven hugely influential for many generations of contemporary artists. Haacke has presented solo exhibitions in such museums as the Tate Gallery, London (1984); the New Museum of Contemporary Art, New York, and tour (1986); and the Musee nationale d'art moderne, Centre Georges Pompidou, Paris (1989), among others. Haacke has participated in such landmark group exhibitions as 'When Attitudes Become Form', Kunsthalle Bern, and tour (1969), and 'Information' at The Museum of Modern Art, New York (1970). He has been featured in four Documentas, Kassel (1972, 1982, 1987 and 1997), both 'Skulptur. Projekte in Munster' exhibitions (1987 and 1997), and three Venice Biennales (1976, 1978 and 1993). |
