In 1900, Ida Hulery Fletcher founded The Portland School of Astrology. In 1901, Fletcher’s student Llewellyn George made an impression on her and she would invite him to become a partner of the School. Other key figures associated with this school are Lewis H. Weston and W.H. Chaney (by way of teaching Portlanders prior to 1900). In October 1911 and for unknown reasons, Llewellyn George would sever his ties with the School and its publishing arm, Bulletina Publishing Co. He would go on to establish his own school and publishing company beginning January 1912: Llewellyn Publishing Co. and the Llewellyn College of Astrology. The Portland School of Astrology continued to operate until about 1914 after which only the bookselling component survived for an additional four years before closing its doors about 1918. Tracking the location of Chaney, Fletcher, George, and Weston throughout the years will also be explored to determine a possible pedagogical lineage. Lastly, the developments of the new school and publishing company will be threshed out to help define the role and involvement of each individual in question.
