Manley Hall was born in 1901,in Peterborough, Canada, to William S. and Louise Palmer Hall. The Hall family moved to the United States in 1904 and lived for a time in Sioux Falls, South Dakota. Manly Hall settled in Los Angeles in 1919.
As a young man he became interested in occult matters. He subsequently joined a number of societies, among them the Theosophical Society, the Freemasons, the Societas Rosecruciana in Civitatibus Foederatis, and the American Federation of Astrologers.
In 1922 Manly Hall wrote his first book on philosophy/religion, Initiates of the Flame. According to Hall, he began collecting works on mysticism and the esoteric sciences: "late in the fall of 1922, the plan for a comprehensive work on the symbolism of western mystical societies began to take shape in my mind. It soon became apparent that research facilities for such a project were not available in Southern California... The only answer was to contact antiquarian book dealers and elict their cooperation in the search for the items desired." The collection of books and manuscripts which Hall purchased, primarily in the 1920s and 1930s, became the basis for his own research and the cornerstone of the Philosophical Research Society's holdings.
