Ralph Tegtmeier (born November 1, 1952), also known as Frater V?D? and Frater U?D? (abbreviation for Ubique Daemon Ubique Deus, "Demon (is) in all, God (is) in all"), is a German occultist, a longtime member of the Fraternitas Saturni, and co-founder of the Illuminates of Thanateros.
Horst E.
Miers in his (German) Encyclopedia of Occult Sciences cites him as the "founder of Pragmatic Magic" whose "works are characterized by an outstanding conciseness".
According to Miers,
While the initial impulses of Pragmatic Magic can be verified as early as Spare and Staudenmaier, its consistent implementation in the German speaking realm was only effected by Frater V?D? who also introduced the term.
He features prominently in Gerhard Mayer's field study of 13 contemporary magicians where he is referenced both under his public magical name Frater V?D? and, perfunctorily anonymized, as Isbrand.
