Title: No Man Knows My History
Content:  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.

In 1851, extracts from what would become History of Joseph Smith were published in a church publication entitled Pearl of Great Price. This book was canonized by the LDS Church on October 10, 1880. The portion of History of Joseph Smith that was canonized consists of Smith's recitation of events between his birth in 1805 and May 1829 and is officially entitled Joseph Smith–History. Although History of the Church is no longer an official publication, it is the most-cited source in two histories of the church which are official publications of LDS Church: Our Heritage: A Brief History of The Church of Jesus Christ of Latter-day Saints and Church History in the Fulness of Times.
