Life history is an interviewing method used to record autobiographical history from an ordinary person's perspective, often gathered from traditionally marginalized groups. It was begun by anthropologists studying Native American groups around the 1900s, and was taken up by sociologists and other scholars, though its popularity has waxed and waned since. One of the major strengths of the life history method is that it provides a kind of voice from a social milieu that is often overlooked or indeed invisible in intellectual discourse.
