Using magnetic sleep techniques, early investigators learned to control switching and trust the patient for guidance in the treatment. Recognition of dissociation as a means of dealing with traumatic material by forming multiple psychic centers led to an effective psychotherapy for multiple personality disorder. The etiological role of child abuse was not acknowledged until modern times, but statistical evidence of sexual crimes against children in late nineteenth-century France may provide a fruitful area of future research. A scrutiny of historical cases raises questions about the univocalness of the concept of multiple personality. It also reveals data that have not yet been fully acknowledged by modern clinicians.342215 bytesapplication/pdfen-USArticle
