In addition to a valuable art collection, the Museum Mayer van den Bergh houses an extensive historical archive. The core of this was bequeathed by Henriette Mayer van den Bergh, the museum's founder. The archive contains a wealth of information about the works of art in the collection, the foundation of the museum, and the eventful lives of Fritz Mayer van den Bergh, his mother Henriette, and the family. In this web dossier, we recount some of these stories.
