Christine “Chris” Costner Sizemore was born on April 4, 1927, and died on July 24, 2016.
She was American writer.
She was an American woman who, in the 1950s, was diagnosed with multiple personality disorder, now known as dissociative identity disorder.
Sizemore case, with a pseudonym used, was depicted in the 1950s book and film The Three Faces of Eve by her psychiatrists, Corbett H. Thigpen and Hervey M. Cleckley.
Chris went public with her true identity in the 1970s.
Her parents were Acie and Zueline Hastings Costner in Edgefield, South Carolina.
It was reported that Sizemore had developed multiple personalities as a result of her witnessing two deaths and a horrifying accident within three months as a small child.
She also at some pointed reported these incidents triggered the evidencing of selves which were already present.
However, “despite authorities’ claims to the contrary, my former alters were not fragments of my birth personality, they were entities, whole in their own rights, who coexisted with my birth personality before I was born -They were not me, but they remain intrinsically related to what it means to be me.
At the time when The Three Faces of Eve was written by Thigpen and Cleckley with limited input from Sizemore, her later books I’m Eve and A Mind of My Own fill in details.
Before in 1958, she had written Strangers in My Body: The Final Face of Eve, using the pseudonym Evelyn Lancaster.
Reported by psychiatrists who worked with her after she moved from South Carolina, Sizemore did not experience three selves, but approximately 20. The doctors reported that her selves presented in groups of three at a time.
She has reported feeling exploited and objectified by the media blitz surrounding the book and film.
In 1988, when she found out that her legal rights to her own life story had been signed away to 20th Century Fox by Thigpen, Sizemore went to Manhattan’s Federal District Court to contest the contract, and won.
Her papers, covering 1952 through 1989, have been acquired by the Duke University Library.
There was an overview of the collection and a summary of Sizemore’s story are included on its website.
She was interviewed on the BBC News channel series Hardtalk on March 25, 2009.
Chris Costner Sizemore passed away at 89 years old.
