2009 reprint of the 1913 third edition. William Walker Atkinson (1862-1932) 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.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.During the 1910s, Atkinson put his attention into another pseudonym, that of Theron Q. Dumont. This entity was supposed to be French, and his works, written in English and published in Chicago, combined an interest in New Thought with ideas about the training of the will, memory enhancement, and personal magnetism. The Art and Science of Personal Magnetism is a product of this period.
