Sally Beauchamp's career: a psychoarchaeological key to Morton Prince's classic case of multiple personality

By the methods of psychoarchaeology, the identity of Sally Beauchamp, Morton Prince's classic case of multiple personality, has been established. The reconstructed life history has for the first time revealed the roots of the dissociative process. This goal was actually obscured by the tangled web of Prince's rambling 1906 book and his other publications on the case. The determinative events included two instances of sudden infant death during the childhood period of the patient, the earlier of which was apparently never even known to Dr. Prince. Though not mentioned in the patient's autobiography, it probably induced the initial dissociation to defend the integration of the personality. The relevance of the new concept of SIDS (since 1969) is considered. Other disturbing influences were the constant rejection of the patient by her mother, who died at an early age, and probable severe abuse by the widowed father which led her to run away from home (permanently) at age 16. Nine years afterward, therapy with Dr. Prince began and lasted seven years. It is suggested that this case and the parallel one of Breuer and Freud (Anna O.) be comparatively reexamined from the standpoint of modern feminism. The role of the conventional 19th-century woman was not acceptable to either of them, and both probably had an unusually large innate, bisexual endowment. Endogenous conflict, intensified by social demands, produced dissociation as a pseudo-solution until, through opportune therapy and other environmental opportunities, each was able to achieve a productive modus vivendi. The relation of bisexuality to the etiology of personality dissociation in general is considered. An incidental but instructive discovery made in the course of the Prince research was an unknown letter from William James to Morton Prince about The Dissociation of a Personality. This find points up the fact that James's final metaphysic was a form of pluralistic panpsychism derived from both psychical research and the contemporary knowledge about dissociated personality. James postulated a cosmic multiple personality.
