Société Thulé
Speculative authors assert that a number of high Nazi Party officials had been members of the Thule Society (including such prominent figures as Max Amann, Dietrich Eckart, Rudolf Hess, Alfred Rosenberg and Gottfried Feder). Eckart, the wealthy publisher of the newspaper "Auf gut Deutsch" ("In Plain German"), has been represented as a committed occultist and the most significant Thule influence on Hitler. He is believed to have taught Hitler a number of persuasive techniques, and so profound was his influence that the second volume of Hitler's book "Mein Kampf" was dedicated to him. However, although Eckart attended Thule Society meetings, he was not a member and there is nothing to indicate that he trained Hitler in techniques of a mystical nature. Examining the membership lists, Goodrick-Clarke notes that Hess, Rosenberg and Feder were – like Eckart – guests of the Thule Society in 1918 but not actual members. He also describes a Thule Society membership roll including Hans Frank and Heinrich Himmler as "spurious". There is no evidence that Hitler himself had any connection with the Society, even as an associate or visitor. However, a member of the Thule Society, dentist Dr. Friedrich Krohn, did choose the swastika symbol for the Nazi party (although the design was revised at Hitler's insistence).
