On the occasion of the 100th birthday of Joseph Beuys (1921-1986) in 2021, the documenta forum e.V., Kassel is supporting the documenta archiv financially with the digitalization and complete indexing of the estate of Dieter Schwerdtle (1952-2009). The photographer is one of the most important chroniclers of the history of post-war Kassel. He has also documented Joseph Beuys' performances at documenta closely. A scholarly textbook with a selection of photographs by Schwerdtle of Joseph Beuys at documenta, particularly of his 7000 oak project, as well as a studio exhibition at the documenta Lab in the Neue Galerie, is planned.
