The Landig Group was an occultist and neo-völkisch group formed in 1950, that first gathered for discussions at the studio of the designer Wilhelm Landig in Vienna's 4th district of Wieden, in Austria. The circle's most prominent and influential members were Wilhelm Landig (1909–1997), Erich Halik (Claude Schweikhart) and Rudolf J. Mund (1920–1985). The circle has also been referred to as the Landig Circle, Vienna Group and Vienna Lodge.
Landig was the founder of the group, that has since inspired decades of völkisch mysticism. He and his group revived the ariosophical, Ario-Germanic mythology of Thule, the supposed polar homeland of the ancient Aryans.
Landig "coined the term Black Sun, a substitute Swastika [and/or Fylfot ] and mystical source of energy capable of regenerating the Aryan race." Landig, through his circle, popularized esoteric ideas current among the pre-Nazi völkisch movement and the SS relating to Atlantis, the World Ice Theory, pre-historic floods and secret racial doctrines from Tibet.
Landig and other occult-fascist propagandists have circulated wild stories about German Nazi colonies that live and work in secret installations beneath the polar ice caps, where they developed flying saucers [see Nazi UFOs] and miracle weapons (Die Glocke) after the demise of the Third Reich. Including the theory that flying saucers were Nazi secret weapons launched from an underground base in Antarctica, from which the Nazis hoped to conquer the world.
The focus of the group’s discussions was a secret center in the Arctic known as the Blue Island, which could serve as a source point for a renaissance of traditional life. This idea was taken from Julius Evola, whose Revolt Against the Modern World became the bible of the Landig group.
Wilhelm Landig 
Landig was a former SS (of Himmler) man whom revived ariosophical mythology of Thule. He coined the idea of the Black Sun, a substitute swastika and mythical source of energy. He was born on 20 December 1909. He wrote Götzen gegen Thule, Rebellen für Thule. Das Erbe von Atlantis and Wolfszeit um Thule.
It has been shown that a younger generation continued the development of the circle's ideas from the 1980s on. This younger generation consisted of members of the German/Austrian Tempelhofgesellschaft. Their publications demonstrate an exchange of ideas with the older generation, mainly revolving around the Black Sun concept. After the Tempelhofgesellschaft had been dissolved, it was succeeded by the Causa Nostra, a Freundeskreis (circle of friends) that remains active.
