Fidus was the pseudonym used by German illustrator, painter and publisher Hugo Reinhold Karl Johann Höppener (October 8, 1868 – February 23, 1948). He was a symbolist artist, whose work directly influenced the psychedelic style of graphic design of the late 1960s.
A. Frank Glahn (1865–1941), was a German mystic, Germanic revivalist, and most notably a pendulum dowser. He was used by the German military in the Third Reich, not necessarily willingly.
Glahn was mentioned greatly in the book Reveal the Power of the Pendulum by Karl Spiesberger.
In 1920 A. Frank-Glahn's "Das Deutsche Tarot Buch" was published by Uranus Verlag, accompanied by a deck of cards "Deutsches Original Tarot", an Egyptian style deck, but unique. Glahn's book and cards became a German tarot bible, which survived up in the 1980s, published by Hermann Bauer Verlag. (K.Frank Jensen)
