The three primary formats used to tell a life story are a biography, an autobiography, and a memoir. Distinguishing between the three can feel a bit confusing since they all share several similarities. But there are some distinct differences.

Simply put, a biography is the life history of an individual, written by someone else.

An autobiography is the story of a person’s life, written by that person. And a memoir is a collection of memories written by the person themselves.

What is a Biography?

A biography, also called a bio, is a non-fiction piece of work giving an objective account of a person’s life. The main difference between a biography vs. an autobiography is that the author of a biography is not the subject.

Biographies include details of key events that shaped the subject’s life, and information about their birthplace, education, work, and relationships. Biographers use a number of research sources, including interviews, letters, diaries, photographs, essays, reference books, and newspapers. While biography is usually in the written form, it can be produced in other formats such as music composition or film.

Examples of famous biographies include:

  • His Excellency: George Washington by Joseph J. Ellis
  • Einstein: The Life and Times by Ronald William Clark
  • Princess Diana — A Biography of The Princess of Wales by Drew L. Crichton

What is an Autobiography?

An autobiography is the story of a person’s life written by that person. Because the author is also the main character of the story, autobiographies are written in the first person.

The purpose of an autobiography is to portray the life experiences and achievements of the author. Therefore, most autobiographies are written later in the subject’s life.

They often begin during early childhood and chronologically detail key events throughout their life. Autobiographies usually include information about where a person was born and brought up, their education, career, life experiences, the challenges they faced, and their key achievements.

One of the main differences between an autobiography vs. a biography is that autobiographies tend to be more subjective. That’s because they are written by the subject, and present the facts based on their own memories of a specific situation, which can be biased.

Examples of famous autobiographies include:

  • The Story of My Life by Helen Keller
  • The Diary of a Young Girl by Anne Frank
  • Losing My Virginity by Richard Branson

What is a Memoir?

Memoir comes from the French word memoir, meaning memory or reminiscence. Similar to an autobiography, a memoir is the story of a person’s life written by that person.

The difference between a memoir vs. an autobiography is that a memoir focuses on reflection and establishing an emotional connection, rather than simply presenting the facts around their life. The author uses their personal knowledge to tell an intimate and emotional story about the private or public happenings in their life. The topic is intentionally focused and does not include biographical or chronological aspects of the author’s life unless they are meaningful and relevant to the story.

Examples of famous memoirs include:

  • Angela’s Ashes by Frank McCourt
  • I Know Why the Caged Bird Sings by Maya Angelou
  • Personal Memoirs of Ulysses S. Grant by Ulysses S. Grant
