Memoir (from French: mémoire: memoria, meaning memory or reminiscence), is a literary nonfiction genre. More specifically, it is a collection of memories that an individual writes about moments or events, both public or private that took place in the author's life. The assertions made in the work are understood to be factual. While memoir has historically been defined as a subcategory of autobiography since the late 20th century, the genre is differentiated in form, presenting a narrowed focus. Like most autobiographies, memoirs are written from the first-person point of view. An autobiography tells the story of a life, while a memoir tells a story from a life, such as touchstone events and turning points from the author's life. The author of a memoir may be referred to as a memoirist.
