Eugen Grosche
Eugen Grosche (11 March 1888, in Leipzig – 5 January 1964), also known as Gregor A. Gregorius, was a German occultist and author. He was founder and Grandmaster of the lodge Fraternitas Saturni from 1926 till 1964. Life and work 
Most of his life Gregorius lived in Berlin. He was initially a member of an Evangelical church and was a member of the Weida Conference in 1925. In the wake of the Conference he founded the Fraternitas Saturni in 1926. Using his own book store and publishing house, he began publishing Magische Briefe (1926-1927), Saturn-Gnosis (1928-1933), and finally, fourteen Lectures of the Lodge-School. During World War II he emigrated to Switzerland in order to avoid imprisonment, but in the course of the war he was arrested for a year by the Nazi government. After World War II Gregorius reformed Fraternitas Saturni. In 1954 he published Die magische Erweckung der Chakra, and in 1960 the novel Exorial. He died in 1964 after a heart attack.
