Wallace Delois Wattles  was an American New Thought writer. He remains personally somewhat obscure, but his writing has been widely quoted and remains in print in the New Thought and self-help movements. Wattles' best known work is a 1910 book called The Science of Getting Rich in which he explains how to become wealthy. Rhonda Byrne told a Newsweek interviewer that her inspiration for creating the 2006 hit film The Secret, and the subsequent book by the same name, was her exposure to Wattles's The Science of Getting Rich. Byrne's daughter, Hayley, had given her mother a copy of the Wattles book to help her recover from her breakdown. The film itself also references, by re-popularizing the term The Law of Attraction, a 1908 book by another New Thought author, William Walker Atkinson, titled Thought Vibration or the Law of Attraction in the Thought World.
