C. Harry (Cyrus Harry) Brooks

C. Harry Brooks, also identified in library and archive records as Cyrus Harry Brooks, is known for The Practice of Autosuggestion, a book first published in 1922 and issued in the United States by Dodd, Mead and Company. The book presents Émile Coué’s ideas in an accessible, non-technical way, and its early reprint history suggests it reached a wide audience.

Brooks wrote as an interpreter of Coué’s method rather than as a dense academic theorist. In the book’s foreword, Coué says Brooks was among the first Englishmen to study the method with him in Nancy, and praises his explanation as simple and clear. Brooks’s writing focuses on self-improvement, mental discipline, and the practical use of suggestion in daily life.

Some sources identify him as a literary agent, and archive records list Cyrus Brooks (1890–1978) under that profession. I could confirm only a small number of biographical facts beyond his authorship, so this picture remains necessarily brief. No suitable verified portrait image was confirmed from the sources I found.
