In June 2000, the Sprengel Museum in Hanover voted to return a Lovis Corinth’s painting, “Walchensee, Johannisnacht” (“The Walchensee on St John’s eve”) which its donor, Dr. Bernhard Sprengel, had purchased from Buchheim, to the heirs of Dr Gustav Kirstein and his wife Therese Clara Stein, who committed suicide due to Nazi persecution.
