The collection of the Städel Museum was removed from the museum to avoid destruction from the Allied bombings, and the collection was stored in the Schloss Rossbach, a castle owned by the Baron Thüngen near Bad Brückenau in Bavaria. There, the museum's paintings and library were discovered by Lt. Thomas Carr Howe, USN, of the American Monuments, Fine Arts and Archives program. Although the Baron von Thüngen and his wife were uncooperative with the Americans, Frau Dr. Holzinger, a licensed physician and the Swiss wife of the Städel Museum director, was present at the site and assisted with the cataloging and the removal of the items to the Munich Central Collecting Point.
