Allen H. Greenfield

Allen H. Greenfield (born 1946), was given the mystical title and charter as Tau Sir Hasirim, in 1986 and 1991 by Hierophant Michael Bertiaux of Chicago IL. Greenfield is an American-born occultist and author long involved in the free illuminist movement.

Greenfield was elected to the mystical episcopate of the Neopythagorean Gnostic Assembly in 1986 and again in 1994, and further consecrated within the Ordo Templi Orientis (OTO) by Frater Superior William Breeze in 1987 and later again by their U.S. Grand Master General David Scriven, but has long parted ways with the OTO in favor of the broadly-based free illuminist movement. His episcopal title "Tau" is sometimes abbreviated as "T" and prefixed to his legal name, and thus he may also be referred to as T Allen Greenfield. A former member of Ordo Templi Orientis and editor of the Eulis Lodge journal LAShTAL, Greenfield has more recently become a critic of the Order's upper management. In February 2006, he called for their resignation and stepped down from all managerial duties in protest, issuing a strong criticism of the current Outer Head of the Order, William Breeze.

A past (elected) member of the Society for Psychical Research and the National Investigations Committee on Aerial Phenomena (from 1960), he has twice been the recipient of the "UFOlogist of the Year Award" of the National UFO Conference (1972 and 1992).

His book Secret Cipher of the UFOnauts ("a very strange book, even for the field of UFOlogy") discusses UFOs in terms derived from Carl Jung, according to Robert Anton Wilson. His The Story of the Hermetic Brotherhood of Light includes discussion of the Hermetic Brotherhood of Light vs. Helena Blavatsky's Brotherhood of Luxor but is, according to a reviewer in Aries, to be used "with care". His book The Compleat Rite of Memphis is a comprehensive history of an Egyptian Rite of Freemasonry, and he edited an authorized, annotated edition of the work Liber Thirty-One by Charles Stansfeld Jones.

Greenfield has devoted the last eight years to the worldwide Free Illuminist or Congregational Illuminist Movement which currently has at least three thousand members.
