Someone else’s life, researched and narrated by a writer, becomes a biography. The biographer gathers letters, interviews, public records, and secondary sources, then constructs a coherent account. The task requires both detective work and narrative skill: facts must be accurate, yet the result must still read as a story rather than a list of dates.

Biographies range from short sketches to multi-volume studies. Some aim for definitive coverage; others focus on a particular aspect of the subject’s life or on a specific period. The relationship between biographer and subject can be admiring, critical, or deliberately balanced. Access to private papers and living witnesses often determines how complete the portrait can be.

Readers turn to biographies for insight into historical figures, artists, scientists, and ordinary people whose lives illuminate larger themes. The form inevitably involves selection and emphasis. A skillful biographer makes those choices transparent enough that the reader can still form an independent judgment. At its best, biography recovers a human life in its particularity and places it within the wider currents of its time.
