Multiple personality has been in the literature for over two hundred years and has recently been the focus of increasing attention. However, nearly all of the cases reported have been primarily descriptive, and even when some theorizing has been ventured, an attempt to integrate the phenomenon of multiple personality with psychosexual development and stages of separation and individuation has not yet been made.

This paper has presented a case of multiple personality treated with psychoanalysis. The ways in which the psychoanalysis has coped with the dissociative phenomena were described and the analytic progress of the patient narrated.
