The Practice of Autosuggestion
by C. Harry (Cyrus Harry) Brooks
About the author
Born in 1890, C. Harry Brooks, also published as Cyrus Harry Brooks, wrote books aimed at general readers who were curious about personal development and the power of suggestion. He is most closely associated with The Practice of Autosuggestion by the Method of Emile Coue, a work that introduced many readers to Coué’s ideas in English.
His known books also include Christianity and Autosuggestion and Your Character from Your Handwriting, showing a wider interest in self-help, belief, and popular psychology. Some library and bookseller records describe him as a literary agent and translator as well as an author.
The sources I found consistently identify him as born in 1890, but they did not clearly support the 1978 death year in your prompt, and one library-style source instead lists 1951. Because of that conflict, it’s safest to say that his work belongs to the early-to-mid 20th century unless a more definitive biographical source turns up.
