PROVIDENCE, R.I.—A federal judge has ruled that a painting in the collection of the German baroness Maria-Luise Bissonnette rightfully belongs to the estate of the late Jewish art dealer Max Stern, who was forced by Nazis to sell it, reports the Associated Press. U.S. District Judge Mary Lisi ordered Bissonnette to turn over the painting, Girl from the Sabiner Mountains, by Franz Xaver Winterhalter, to Stern's estate. Stern, who died in 1987, inherited his family's Dusseldorf art gallery in 1934 but was forced to auction off its contents three years later because he was a Jew. He was not allowed to keep the proceeds, and he fled to Canada, where he continued to work as an art dealer. Bissonnette's stepfather, a Nazi party member, bought the painting at auction. She resettled in Rhode Island and inherited the work from her parents. Stern left his estate to McGill and Concordia universities in Canada and Hebrew University in Jerusalem; the schools have continued his search, started after the war, for the paintings he lost. They found the Winterhalter work when Bissonnette tried to auction it in 2005. About 400 works from Stern's collection are still missing.
