Samuel Clemens (Mark Twain) began writing his autobiography long before the 1906 publications of these Chapters from my Autobiography. He originally planned to have his memoirs published only after his death but realized, once he’d passed his 70th year, that a lot of the material might be OK to publish before his departure. These chapters were published in serial form in the North American Review during 1906-1907. While much of the material consists of stories about the people, places and incidents of his long life, there’re also several sections from his daughter, which he calls “Susy’s biography of me”.
