The deluxe edition includes quotes and extra pages for notes. 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 thought to be the author of the pseudonymous works attributed to Theron Q. Dumont and Yogi Ramacharaka. He is the author of an estimated 100 books, all written in the last 30 years of his life. He was also mentioned in past editions of Who's Who in America, Religious Leaders of America, and several similar publications. His works have remained in print more or less continuously since 1900. Mental Science and New Thought Some time after his healing, Atkinson began to write articles on the truths he felt he had discovered, which were then known as Mental Science. In 1889, an article by him entitled "A Mental Science Catechism," appeared in Charles Fillmore's new periodical, Modern Thought. By the early 1890s Chicago had become a major centre for New Thought, mainly through the work of Emma Curtis Hopkins, and Atkinson decided to move there. Once in the city, he became an active promoter of the movement as an editor and author. He was responsible for publishing the magazines Suggestion (1900-1901), New Thought (1901-1905) and Advanced Thought (1906-1916). In 1900 Atkinson worked as an associate editor of Suggestion, a New Thought Journal, and wrote his probable first book, Thought-Force in Business and Everyday Life, being a series of lessons in personal magnetism, psychic influence, thought-force, concentration, will-power, and practical mental science. He then met Sydney Flower, a well-known New Thought publisher and businessman, and teamed up with him. In December, 1901 he assumed editorship of Flower's popular New Thought magazine, a post which he held until 1905. During these years he built for himself an enduring place in the hearts of its readers. Article after article flowed from his pen. Meanwhile he also founded his own Psychic Club and the so-called "Atkinson School of Mental Science". Both were located in the same building as Flower's Psychic Research and New Thought Publishing Company.
