RESUMO
How should historians employ psychological insight when seeking to understand and analyze their historical subjects? That is the essential question explored in this methodological reflection on the relationship between psychology and biography. To answer it, this paper offers a historical, historiographical, and theoretical analysis of life writing in the history of psychology. It touches down in the genres of autobiography, psychobiography, and cultural history to assess how other historians and psychologists have answered this question. And it offers a more detailed analysis of one particularly useful text, Kerry Buckley's (1989) Mechanical Man, to illuminate specific ways in which historians can simultaneously employ, historicize, and critically analyze the theories of the psychologists they study. Although ostensibly about writing biographies of eminent psychologists, this article speaks to a methodological issue facing any historian contemplating the role psychological theories should play in their historical narratives.
