The Deutsches Opernhaus is an opera house in Berlin.
In February 1934, Adolf Hitler attended a representation of Richard Wagner's opera Parsifal at the Deutsches Opernhaus in Berlin, with all the audience waiting to see Hitler's reactions before applauding the performance.
During the ensuing gala dinner, Hitler praised some aspects of the play that linked to his own line of thought, such as celebrating the purity of blood that must be safeguarded, while constructing a new aristocracy based on it.
Johann Schmidt, a university researcher in the field of physics, interrupted Hitler saying that the old ways should not be disposed, as they could prove to be more than they appeared. After apologizing, Schmidt revealed that Wagner's music had influenced his work just as it "inspired" Hitler to set Germany back on a path of greatness.
Hitler asked for the link between Wagner and physics, and Schmidt answered that the "magic" from the Norse mythology that Wagner adapted into his operas could simply be the oldest science ever known. Intrigued by Schmidt's ideas, Hitler asked Ernst Kaufmann to arrange a lunch between Hitler and Schmidt to discuss the ideas.
Schmidt asked Kaufmann, leader of the special weapons division, to continue his research in his division, but Kaufmann, displeased with Schmidt's interruption, was threatened and warned not to come near Hitler again. However, Heinrich Himmler, head of the Schutzstaffel, overheard Schmidt's theories, and took him under his wing.
