A case in US courts is a battle over art looted by Nazis. “The case pits an ailing, elderly German baroness in Providence against a wealthy Canadian foundation created to benefit three universities in Canada and Israel. And it involves a Jewish lawyer in Boston who has helped Jewish families recover art lost during the Holocaust, but who now represents the baroness in a dispute over whether she possesses art stolen by her Nazi stepfather — and whether she broke the law by taking the painting to Germany in search of an overseas court sympathetic to her position.”
