Grand Duchy of Mecklenburg-Schwerin
From 1911 to 1939 the folklorist, Richard Wossidlo, lived for periods of time in several rooms in Weinberg House, in which he had housed his numerous records, library holdings and his private folk museum. In 1912, when the collection became too large, Wossidlo sold this museum collection with about 3,400 exhibits to the Grand Duchy of Mecklenburg-Schwerin.
