 According to Hitler biographer Ian Kershaw, the organization's "membership list ... reads like a Who's Who of early Nazi sympathizers and leading figures in Munich", including Rudolf Hess, Alfred Rosenberg, Hans Frank, Julius Lehmann, Gottfried Feder, Dietrich Eckart, and Karl Harrer.Author Nicholas Goodrick-Clarke contends that Hans Frank and Rudolf Hess had been Thule members, but other leading Nazis had only been invited to speak at Thule meetings or they were entirely unconnected with it.According to Johannes Hering, "There is no evidence that Hitler ever attended the Thule Society."
