As a literary genre, a memoir (from the French: mémoire from the Latin memoria, meaning "memory"), or a reminiscence, forms a subclass of autobiography – although the terms 'memoir' and 'autobiography' are today almost interchangeable. The author of a memoir may be referred to as a memoirist.
***Nature of Memoirs***
Memoirs may appear less structured and less encompassing than formal autobiographical works as they are usually about part of a life rather than the chronological telling of a life from childhood to adulthood/old age. Traditionally, memoirs usually dealt with public matters, rather than personal, and many older memoirs contain little or no information about the writer, and are almost entirely concerned with other people. They tended to be written by politicians or people in court society, later joined by military leaders and businessmen, and often dealt exclusively with the writer's careers rather than their private life. Modern expectations have changed this, even for heads of government. Like most autobiographies, memoirs are generally written from the first person point of view.
Gore Vidal, in his own memoir Palimpsest, gave a personal definition: "a memoir is how one remembers one's own life, while an autobiography is history, requiring research, dates, facts double-checked." It is more about what can be gleaned from a section of one's life than about the outcome of the life as a whole
