Sigmund Freud's analysis of da Vinci (titled "Leonardo da Vinci and a Memory of His Childhood") is generally considered to be the first "modern" psychobiography. Persons who have been the subject of much psychobiographical research over the years include Freud, Adolf Hitler, Sylvia Plath, Carl Jung, Vincent van Gogh, Abraham Lincoln, Gordon Allport, Elvis Presley, and Richard Nixon, among others. A lot of psychobiography is Freudian or psychodynamic in orientation, but other commonly used theories include narrative models of identity (such as Dan McAdams's life story model), script theory, object relations, and existentialism/phenomenology.
The discipline of psychobiography has developed various methodological guidelines for psychobiographical study (see, for examples of many of these, Schultz, 2005). Some of the most prominent are these:
1. The use of prototypical scenes in the life of the subject to serve as a model of their personality pattern
2. The use of a series of indicators of salience, markers such as primacy, frequency, and uniqueness of an event in a life, to identify significant patterns
3. The identification of pregnant metaphors or images that organize autobiographical narratives
4. Logical coherence or consistency as a criterion for adequate psychological interpretations
It is worth noting, however, that there continue to be psychobiographical studies produced by scholars untrained in the discipline who do not follow these guidelines.
The most productive psychobiographers working today are William Todd Schultz and Alan C. Elms (Schultz was Elms's student at UC Davis). Schultz's book is listed below; Elms's is titled Uncovering Lives: The Uneasy Alliance of Biography and Psychology. Schultz maintains a very useful website on psychobiography (http://www.psychobiography.com), as does Elms (http://www.ulmus.net).
Other important psychobiographical authors include Erik Erikson, Irving Alexander, James A. Anderson, Henry Murray, Dan Ogilvie, Nicole Barenbaum, George Atwood, William Runyan, and Robert White.
