Bradley, Donald A. (Garth Allen)

(religion, spiritualism, and occult)

Donald A. Bradley, born in Nebraska on May 16, 1925, was a leader of the “siderealist” movement and research director of the Llewellyn Foundation for Astrological Research. He carried out several statistical studies, including an astrological analysis of 2,492 clergymen and an extensive study of rainfall. His results, while initially greeted with enthusiasm, were later shown to be largely insignificant, either because of faulty design or neglected statistical considerations.

Bradley was an enthusiastic adherent of the sidereal zodiac as advocated by Cyril Fagan, and wrote many books and articles on siderealism. He published his early work under his own name but later used the pseudonym Garth Allen. A regular contributor to American Astrology Magazine, he was senior editor when he died of cancer on April 25, 1974, in Tucson, Arizona.
