William Walker Atkinson

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 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.
