Katharina Wagner, who co-runs the legendary Bayreuth Festival dedicated to the works of her great-grandfather Richard Wagner, dampened hopes Sunday that letters between Adolf Hitler and the Wagner family could be published. In an interview in the Sunday edition of the Tagesspiegel newspaper, Katharina reiterated her pledge to hand over the private papers of her father, Wolfgang Wagner, to the Bavarian State Archive, with the aim of shedding new light on the festival's history. "This will mean that historians and scholars can have access to this material," she said.
