Hauer was involved with the SS from the beginning, and it was the SS too that three years later demanded his resignation from the movement. Hauer’s worldview and that of the SS were ideologically compatible. But Hauer’s personality and his personal charisma were not. Himmler, Heydrich and Wüst eventually opposed Hauer. Nevertheless, students from his Aryan Institute were hired by the SS, although they were routinely subjected to sharp and critical observation.1 What they lacked was a Führernatur, a combination of hardness, sobriety, and comradeship. But like the SS, they had learned from Hauer to approach their research and work from a worldview perspective.
