A biography is the story of a real person’s life, told by someone else. If you need to define biography in plain words, that is the core idea: a factual account of a life, written by an author who is not the subject.

Define Biography in Simple Words
To define biography simply, it is a written account of a person’s life by someone else. Oxford Learner’s Dictionaries gives this meaning and also uses the word for the genre of writing itself. A biographer collects facts, talks to people who knew the subject, and shapes it all into a story. Vocabulary.com adds that a biography covers the most important events of a life, so it is selective and not a record of every day.
What Is a Biography: Meaning and Purpose
When people ask what is a biography, they usually want to know what it is for. The British Academy says one purpose is to take readers into a life unlike their own, which widens understanding and helps them imagine being someone else. The meaning of biography is tied to its roots. The word comes from Greek roots for life and writing, so it literally means writing about a life. Biography as a practice is much older than the word, as the next section shows.
Origin and History of Biography
The British Academy points to ancient examples such as the Gilgamesh epic, classical accounts of rulers and religious lives of holy figures. Early biographies mostly celebrated prominent men as models to follow. Wikipedia lists classic works such as Plutarch’s Parallel Lives, which pairs famous Greeks with famous Romans, and Vasari’s Lives of the Artists. It also names Boswell’s The Life of Samuel Johnson. Over time the form widened. The British Academy notes that biography later came to include ordinary people, not only the famous.
Define Biography in Literature
In literature, biography is a nonfiction genre built around the life of a real person. Many readers define biography in literature by what it is not. The British Academy separates it from fiction, because a biography should stay factual, and from history, because a biography centers on an individual. It also differs from psychology, since biographers study character and motives without being trained psychologists. Under any biography definition in literature, the writer’s viewpoint still matters. The British Academy points out that no biographer is fully objective, because every writer is shaped by their own background and era.
Biography in a Sentence
Seeing biography in a sentence helps the meaning stick. These are original examples:
- She spent three years researching a biography of the painter.
- The library keeps a short biography of every author in the collection.
- His biography reads like a novel, but it is built from letters and interviews.
- The documentary is a biography told through film instead of print. They show that the word can describe a book, a short profile or a film.
Elements of a Biography
The elements of biography are the building blocks every writer works with. Wikipedia describes a biography as more than basic facts such as education, work, relationships and death. It also covers how the person experienced those events and may analyze their personality. Most biographies share these elements:
- Early life and family background
- Key events and turning points
- Work, achievements and public impact
- Personal life and relationships
- The historical setting that shaped the person
- Sources such as interviews, letters and records
- The writer’s point of view and purpose Together these turn a list of dates into a story.
Types of Biography
The types of biography depend on permission, format and length. Wikipedia lists authorized biographies, written with the permission of the subject or the family, and unauthorized biographies, written without it. Autobiography also appears as a type, though the subject writes it, sometimes with a collaborator or ghostwriter. The British Academy adds that biographies appear as films, poems, obituaries and operas, and can cover groups, cities and even animals. A short biography, also called a brief or mini biography, gives only the key facts in a few paragraphs. You often see it in author notes, speaker introductions and reference sites.
What a Biography Includes
What does a biography include? Wikipedia says it covers education, work, relationships and death, along with how the person experienced those events. A good biography also explains why events mattered, not just when they happened. Strong biographers back claims with sources such as interviews, letters, records and news reports. They also show the era, the people around the subject and the choices the subject faced.
Biography vs Autobiography: Key Differences
Biography vs autobiography is the most common comparison, and the main difference is who writes the story. Oxford Learner’s Dictionaries defines a biography as written by someone else and an autobiography as written by the person themselves. Autobiography vs biography also differs in perspective and sources. Writers.com says a biographer works as an outside observer using interviews and reporting, while an autobiographer starts from memory and builds on facts and research.
| Feature | Biography | Autobiography |
|---|---|---|
| Who writes it | Someone other than the subject | The subject, sometimes with a ghostwriter |
| Point of view | Outside observer, usually third person | Inside view, usually first person |
| Scope | Usually a whole life | Broad, often a whole life or a major part of it |
| Main sources | Interviews and reporting | Memory, backed by facts and research |
| Tone | Often the most objective | Fact focused, often seen as a legacy |
| Example | American Prometheus by Kai Bird and Martin J. Sherwin | I Know Why the Caged Bird Sings by Maya Angelou |
What Is the Difference Between a Biography and an Autobiography
The difference between biography and autobiography comes down to the author. In a biography, the writer researches someone else’s life. In an autobiography, the writer tells their own life. Writers.com notes that a ghostwriter may help with an autobiography, but the subject’s name is still on the cover. A quick test works well: if the author is the subject, it is an autobiography.
Biography vs Autobiography vs Memoir
When you define biography, autobiography and memoir side by side, scope is the clearest dividing line. Writers.com describes a memoir as narrow and zoomed in on a smaller span of time. An autobiography is broad and covers a whole life or a major part of it. Memoir vs biography is simple too. A memoir is written by the subject about a few key events and themes, while a biography is written by an outsider about a whole life. Memoirs lean on memory, and authors often question how accurate their memories are.
| Feature | Biography | Autobiography | Memoir |
|---|---|---|---|
| Who writes it | Someone else | The subject | The subject |
| Scope | Usually a whole life | Broad | Narrow, a few events or a period |
| Inside view | Least personal | Can be quite personal | Most personal |
| Main source | Interviews and reporting | Memory plus research | Memory supported by research |
| Tone | Often the most objective | Fact focused | Personal and often literary |
Real Examples of Biography and Autobiography
These real examples help define biography in practice. Writers.com names American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer by Kai Bird and Martin J. Sherwin as a biography. For autobiography, Writers.com lists I Know Why the Caged Bird Sings by Maya Angelou. For memoir, it names The Year of Magical Thinking by Joan Didion and My Salinger Year by Joanna Rakoff. Classic examples include Boswell’s The Life of Samuel Johnson and Plutarch’s Parallel Lives, both listed by Wikipedia. Modern biographies of this kind help readers see how the genre works.

Is a Biography Nonfiction
Is a biography nonfiction? Yes. It is meant to be factual, which is why libraries shelve it with nonfiction. The British Academy notes that writers still choose what to include and what to leave out, so no biography is a perfect mirror of a life. Is a biography written by someone else? Almost always. If the subject writes it, the book is an autobiography or a memoir. Is a biography only for the dead? No, the British Academy says it can cover living people, and Vocabulary.com says the subject can be any age.
Biography vs Bibliography
Biography vs bibliography is a common mix up. Oxford Learner’s Dictionaries defines a bibliography as a list of books or articles on a subject or by an author, or the list of sources a writer used. It can also mean the study of books and how they were produced. A biography, by contrast, tells a life story. If you write a biography, you will end it with a bibliography of your sources.
How to Pronounce Biography
How to pronounce biography depends on where you are. Oxford Learner’s Dictionaries gives /baɪˈɒɡrəfi/ for British English and /baɪˈɑːɡrəfi/ for American English. In simple spelling, that is roughly “by-OG-ruh-fee” in British English and “by-AH-gruh-fee” in American English. The stress falls on the second syllable in both.
Another Word for Biography
Another word for biography includes life story, life history and simply life, according to Vocabulary.com. Related words include profile, which is a short biographical sketch, and hagiography, which is an idealized account, often of a saint. There is no true opposite, but autobiography is the closest contrast because the subject writes it. Memoir is related, though it focuses on the author’s own experiences instead.
Final Thoughts
To define biography in one line, it is a factual life story written by someone other than the subject. Knowing the difference between biography, autobiography and memoir helps you choose the right book and write the right kind of profile in 2026. For more real examples, browse the Biography category.
