The Doris Fischer case concerns a woman with multiple personalities dating back to the age of three. Some of the personalities were created from traumatic events, others the origins of are unknown. This case is remarkable because it involves a personality that is a subliminal co-conscious personality that can co-exist at the same time as another personality and can take over when necessary. Doris was under observation daily and hourly for almost four years. In all Doris is said to have five separate personalities. Each personality and the actions of each is discussed in detail by Dr. Prince.
Dr. Prince discusses the case of Miss Beauchamp, one of his patients who suffered from multiple personalities. Miss Beauchamp’s 2nd personality was named Sally. Sally would do whatever she could to annoy Miss Beauchamp, even going so far as to get her lost in the country. Sally would even correspondence with Miss Beauchamp. In 1899 a third personality came out after a disturbing incident. At first this personality was thought to be the true Miss Beauchamp, but that idea was soon discarded. Dr. Prince discusses the causes and memories of each of the personalities, he charts the existence of each personality.
This is a book review of Dr. Prince’s book “The Dissociation of a Personality.” The book discusses the multiple personality case of Miss Beauchamp. The patient had three distinct personalities only one of which was aware of all of the activities of the other personalities. This personality, ‘Sally’ often tormented her co-personalities. It is noted that this aspect of the case makes Miss Beauchamp a worthy subject for a book about her case.
