Input: Question: Was Kassel the capital of a country at the time? Passage:After his school-leaving examination (Abitur) at the secondary school Antonianum in Vechta Ludger Gerdes studied at the Academy of Arts in Münster with Timm Ulrichs and Lothar Baumgarten from 1975 to 1977, and from 1977 to 1982 at the Düsseldorf Academy of Arts with Gerhard Richter. At the beginning of the 1980s Gerdes stood out in exhibitions and actions with his criticism of the link between modern art, the museum and the temporary exhibition. At this time he exhibited among others along with Thomas Schütte. He pleaded for works of art as a means for the organization of public space and as a medium of communication. The English landscape garden was a particularly important historical model of this to him. At this time he was regarded as the intellectual head of the artist-group of Düsseldorf pattern makers (Düsseldorfer Modellbauer). In 1982 he was included in the documenta 7 in Kassel. He became known to a larger public in 1987 with his land art project A Ship for Münster (Ein Schiff für Münster) for the show "Skulptur.Projekte" in Münster. From 1990 to 1992 he taught at the Städelschule, Frankfurt; from 1998 to 2004 he was professor for painting and multimedia at the art academy in Karlsruhe; since 2005 he was professor for painting at the Muthesius Art Academy in Kiel. Parallel to his professorship he lived and worked as an artist in Munich and Düsseldorf.
