No Man Knows My History: The Life of Joseph Smith is a 1945 book by Fawn M. Brodie, one of the first significant non-hagiographic biographies of Joseph Smith, the progenitor of the Latter Day Saint movement. No Man Knows My History has never been out of print, and 60 years after its first publication, its publisher, Alfred A. Knopf, continues to sell about a thousand copies annually. For a revised edition released in 1971, Brodie added a supplement incorporating psychohistorical commentary. In 1995, Utah State University (USU) marked the 50th anniversary of the book's first publication by hosting a symposium to re-examine the book, its author, and her methods, and in 1996 USU published the symposium papers as a book of essays. No Man Knows My History was influential in the development of Mormon history as a scholarly field, though historians of Mormonism have since criticized the book for its methodological deficiencies, factual errors, and overt hostility to Smith.
