Understanding Autobiography

Writing an autobiography is different from a biography, although both describe the character of the story of one's life. 

An autobiography is a description of a person’s life written by that person. As the book is written by the author, they are the main characters. 

The aim of writing an autobiography is to describe the achievements and life experiences of the narrator. The autobiography format typically starts with early childhood and chronologically lists down life experiences. 

These include information about a person’s childhood, career, life choices, achievements, and the difficulties they face. 

Key Traits of an Autobiography

  • Written in the first person 
  • More subjective than biographies
  • Broad in scope often covers the writer’s entire life up to the present
  • Inform and explain the motive behind the subject’s actions

The “Story of My Life” by Helen Keller is a famous example of an autobiography.

Understanding Biography

A biography is the story of a person’s life written by someone else. Usually, people write biographies about famous personalities. 

Since the writer is telling the story of someone, that’s why biographies include a third-person perspective. 

Like an autobiography, biographies also cover the entire subject’s life. So, it is important to include details about birthplace, education, childhood, relationships, etc. 

Key Traits of a Biography

  • Written in the third person point of view
  • Follows chronological order
  • More formal than autobiographies
  • Cover the subject’s entire life
  • Requires more research and fact-checking to ensure all the details are correct

“His Excellency: George Washington” by Joseph J. Ellis and “Steve Jobs” by Walter Isaacson are some of the key examples of a biography.

How are they Different from a Memoir?

A memoir is similar to an autobiography as it is also the story of a person’s life written by that person.

Whereas a biography provides full contextual information that reads like a novel but is non-fiction in nature.

“The Diary of a Young Girl” by Anne Frank is a famous example of a historic memoir.
