Donald A. Westbrook (1985-) received his Ph.D. in Religion from Claremont Graduate University (CGU) in 2015. His dissertation,
“A People’s History of the Church of Scientology,” was produced with logistical assistance from the Church of Scientology
International in Los Angeles and based on formal and informal interviews with dozens of Scientologists across the United States,
with the largest number conducted in the Greater Los Angeles Area.
This collection includes books, lectures, periodicals, Freedom of Information Act (FOIA) documents, and ephemera, as well
as a copy of Westbrook's dissertation, and was accumulated over four years by Westbrook as part of his intensive ethnographic
research on Scientology. Materials date as far back as 1950 when Hubbard authored a number of works, including
Dianetics: The Modern Science of Mental Health.
