When I first found some of his books, they seemed authentic until recently when I wanted to find out more about this Yogi, his background, and his relevance as an Indian authority on Yoga.
Rather than go into a lot of redundant detail, I’ll present my findings below and let you make your decision.
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.
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.
