 Michael Bertiaux

Michael Paul Bertiaux (born January 18, 1935) is an American occultist and Old Catholic Bishop, known for his book "Voudon Gnostic Workbook" (1988), a 615-page compendium of various occult lessons and research papers spanning the sub-fields of Voodoo, Neo-Pythagoreanism, Thelema and Gnosticism.Long considered by occultists one of the underground classics of 20th century occultism, the book was out of print for many years and fetched increasingly high prices in the antiquarian market before it was reprinted in paperback by Red Wheel/Weiser in 2007.
