He was a Freemason and a practitioner of meditation, astrology, numerology, and alchemy. Glauer was initially interested in Theosophy and Freemasonry. In 1901 he was initiated by a family of Greek-Jewish Freemasons into a lodge which is believed to have been affiliated to the French Rite of Memphis.
