ABSTRACT
Milton H. Erickson, M.D., became interested in multiple personaUty in the 1940's when it was not as fashionable as it is today. He considered it an exceptional opportunity to learn about the development, organization, and structure of the human personality. He wondered how two separate personalities could develop within the same person when they had identical life experiences. Before he died, he had seen 23 cases. Although he wrote on the subject, he never wrote a definitive paper, and several of his writings were published posthumously (Erickson, circa 1940's/1980; Erickson & Kubie, 1939/1967; Erickson & Rapaport, circa 1940V1980; Haley & Richeport, 1955/1991). Few of his students were interested in the subject at the time, although Beahrs (1982,1986) and Haley most closely follow Erickson's approach.
