A commission has recommended that four paintings contained in a vast Vienna art collection should be returned because they were either seized by the Nazis or given up against the will of their former Jewish owners, Austria’s Culture Ministry said Monday. The paintings — one by Egon Schiele and three by Anton Romako — belong to the Leopold Museum Private Foundation, which has been criticized by the Jewish community and others for allegedly containing works stolen by the followers of Adolf Hitler. The commission said the Romako works — The Spring, Nike with Wreath and Young Girl, Nude — used to belong to Oskar Reichel, a Jewish doctor who lived in the Austrian capital.While it was unclear if the works were actually confiscated by the Nazis, “it is certain that Dr. Oskar Reichel had to give up all three paintings because of his persecution as a Jew by the National Socialists,” the commission said in a document detailing its decision.
