The official astrologer of the Hermetic Brotherhood of Luxor, later the Brotherhood of Light, Minnie Higgin died in 1909 creating a vacancy that was filled by Elbert Benjamine, who began the following year to write the Brotherhood lessons. In 1894 she lived in the home of Henry and Belle Wagner at 1258 Downing Avenue, where the city directory listed her as an astrologer. In the 1900 census she resided in a rooming house and was described as an astrologist. She wrote the introduction to the 1900 Part II of The Light of Egypt making her part of that mysterious collaboration.
