William Walker Atkinson (December 5, 1862 – November 22, 1932) was an attorney, merchant, publisher, and author, as well as an occultist and an American pioneer of the New Thought movement. He is also known to have been the author of the pseudonymous works attributed to Theron Q. Dumont and Yogi Ramacharaka, as well as Magus Incognito. Due in part to Atkinson's intense personal secrecy and extensive use of pseudonyms, he is now largely forgotten, despite having obtained mention in past editions of Who's Who in America, Religious Leaders of America, and several similar publications—and having written more than 100 books in the last 30 years of his life. His works have remained in print more or less continuously since 1900. The Secret Doctrines of the Rosicrucians by Magus Incognito consisted of a nearly verbatim republication of portions of The Arcane Teachings, an anonymous work attributed to Atkinson (see below). The doctrine behind The Arcane Teaching is remarkably similar to the philosophy in The Kybalion (another title attributed to Atkinson). This edition of The Secret Doctrines of the Rosicrucians is specially formatted with a Table of Contents and illustrations.
