Archival material

The estate of the important 19th-century German economist Johann Heinrich von Thünen has been in the possession of the University of Rostock since 1902 as the Thünen Archive. During the Second World War, this archive was moved to Wiligrad Castle, from where it could not be returned in its entirety in 1946. A box containing approximately 3,000 original Thünen letters is missing from this archive. These letters were still seen at Wiligrad Castle in January 1946, but were not handed over by the Soviet Military Administration.
