"Dr. Julius F. Sachse, the first Librarian and Curator of the Masonic Temple, discovered this previously unknown image of Franklin hanging in the Lodge Room in Gottingen, Germany, where it had hung for more than a hundred years at that time. It is a documented fact that Franklin was in the town of Gottingen when he visited Europe." That data was copied from the Temple's information card.

Although the 1910 Abstract of Proceedings does not specifically mention the miniature, it does note that Dr. Sachse spent $2495.42 on "Antiquities for Museum" when he traveled to Europe to acquire objects for the collection.
