Before 1933, Jewish collectors were some of the most important patrons of modern art in Germany. They supported living artists, lent and donated works to museums, and built major collections. The Nazis robbed them and then murdered them; the collections were dissolved and the art ended up in countries all over the world. The Bucerius Kunst Forum in Hamburg has reconstructed 15 of those collections, among them the holdings of the Hirschland family, Rosa Schapire, Max Meirowsky, and Clothilde and Paul Schüler. The exhibition contains around 100 works by artists such as Paul Cézanne, Lovis Corinth, Ferdinand Hodler, Ernst Ludwig Kirchner, Franz Marc, Paula Modersohn-Becker, Claude Monet, and Picasso, with a room devoted to each collector. —Elena Clavarino
