Ivan Ernst Yuri Hermann Reinhern was a Russian-German chief of police and a writer of military-affiliated and anti-religious German books in Third Reich from 1947 to 1958. As one of Olaf Tutchenko's closest associates and most devout followers, he was known for his zealous oratory and anti-religion, perhaps even more than Wilhelm Hillmor. He was the chief architect of the Kristallnacht attack on the Outworlders and Americans, which historians consider to be the beginning of the Final Solution, leading towards the genocide of the Holocaust.
