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 the author of the pseudonymous works attributed to Theron Q. Dumont and Yogi Ramacharaka. Atkinson apparently enjoyed the idea of writing as a Hindu so much that he created two more Indian personas, Swami Bhakta Vishita and Swami Panchadasi. Strangely, neither of these identities wrote on Hinduism. He wrote an estimated 100 books, all in the last 30 years of his life. He was mentioned in past editions of Who's Who in America, in Religious Leaders of America, and in similar publications. His works have remained in print more or less continuously since 1900.
