BERLIN (AP) — A commission in Germany has ruled that a painting by expressionist Erich Heckel that is in a German art museum was likely unlawfully obtained under the Nazis and should be returned to the heirs of a Jewish historian who once owned it. The commission said Heckel’s “Geschwister,” or “Siblings,” was owned by Jewish historian Max Fischer until 1934, the year before he fled Germany. The 1913 painting ended up back with Heckel, and the artist donated it to the Kunsthalle Karlsruhe museum in 1967. The commission said Tuesday that it had to assume Fischer lost possession of the painting due to Nazi persecution. His heirs have said they plan on donating the piece to the Virginia Museum of Fine Arts.
