Promises: Katharina Wagner has said she will pass over her father's letters to historians to be examined The heirs of composer Richard Wagner have pledged to allow researchers access to private archives to determine the family's links with the Nazis. This Wednesday will mark the 200th anniversary of Wagner's birth but his reputation has been linked to the Nazis regime. However, his great-granddaughter Katharina Wagner has now said she will pass over private letters and correspondence belonging to her father to historians to be examined. Ms Wagner's father, Wolfgang Wagner, was a former member of the Hitler Youth as well as a  Wehrmacht soldier who ran the Bayreuth festival between 1951 to 2008.
