Bayreuth Festival
The opening took place on August 13, 1876, with a performance of Das Rheingold. A lot of important people were there, including Kaiser Wilhelm, Dom Pedro II of Brazil, King Ludwig (who came in secret, perhaps because he did not want to meet the Kaiser), and other members of the nobility, as well as the philosopher Friedrich Nietzsche, and the composers Anton Bruckner, Edvard Grieg, Pyotr Tchaikovsky, and Franz Liszt.  Hans Richter was the conductor.
