Samuel Liddell (or Liddel) MacGregor Mathers (8 or 11 January 1854 – 5 or 20 November 1918), born Samuel Liddell Mathers, was a British occultist and member of the S.R.I.A.. He is primarily known as one of the founders of the Hermetic Order of the Golden Dawn, a ceremonial magic order of which offshoots still exist. He became so synonymous with the order that Golden Dawn scholar Israel Regardie observed in retrospect that "the Golden Dawn was MacGregor Mathers."
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)
