What does the biography take away from the autobiography? how does autobiographical and biographical narratives historians?

1. The biography and the autobiography have lot of things in common, but they also have few differences. The biggest and most important difference between the two is that the biography is written for someone by someone else, while the autobiography is written by person himself/herself it is about. This leads us to say that the biography is taking away the personal opinion and person expressions of the person whose life is described, as it only offers the perspective from the other people, or a single person.

2. The biography and the autobiography are of great help for the historians. The biography offers the view of a particular person for the person in question, be it the action that person has done, the physical appearance, the character etc. The autobiography, on the other hand, gives clues about how the person in question has viewed himself/herself, and how that person was seeing the world and their own actions and behavior. Both combined, give a nice perspective from two sides, which gives clues about the real historical events.
