Wolfgang Wagner
Wolfgang Wagner (born 30 August 1919 - 21 March 2010) was a German opera director.  He was the grandson of the opera composer Richard Wagner and great-grandson of the composer Franz Liszt.  For 42 years he was director of the Bayreuth Festival, which was created by Richard Wagner for the performances of his operas.  At first he was director together with his brother Wieland.  After Wieland died he continued to be director until he retired in 2008.  He tried to get rid of the festival’s Nazi past, and put on productions which were very symbolic: using lighting effects instead of complicated scenery and heavy costumes.
