A biography is a detailed description or account of someone's life. More than a list of basic facts (education, work, relationships, and death), a biography also portrays a subject's experience of these events. Unlike a profile or curriculum vitae (résumé), a biography presents a subject's life story, highlighting various aspects of his or her life, including intimate details of experience, and may include an analysis of a subject's personality.
Biographical works are usually non-fiction, but fiction can also be used to portray a person's life. One in-depth form of biographical coverage is called legacy writing. Biographical works in diverse media—from literature to film—form the genre known as biography.
An authorized biography is written with the permission, cooperation, and, at times, participation of a subject or a subject's heirs.
An autobiography is about a life of a subject, written by that subject or sometimes with a collaborator.
Walter "Walt" Whitman (May 31, 1819 – March 26, 1892) was an American poet, essayist and journalist. A humanist, he was a part of the transition between transcendentalism and realism, incorporating both views in his works. Whitman is among the most influential poets in the American canon, often called the father of free verse.
