On May 30, 2000, the museum and the State Art Collections in Dresden, Germany (Staatliche Kunstsammlungen Dresden), announced an agreement for the return of five pieces of armor stolen from Dresden during World War II. In 1953, Von Kienbusch had unsuspectingly purchased the armor, which was part of his 1976 bequest. Von Kienbusch published catalogs of his collection, which eventually led Dresden authorities to bring the matter up with the museum.Carl Otto Kretzschmar von Kienbusch and the Collecting of Arms and Armor in America, Donald J.
