Biography (historical profile)

Chris Costner Sizemore is a historically notable American figure associated with the study of dissociative identity disorder (DID). Public records and biographical sources identify her as the woman whose case was presented in the 1957 book The Three Faces of Eve, which described multiple alternate identities within a single person and helped raise public awareness of DID at the time.

Birth year is generally cited as 1927. Exact birth location in public biographies varies across sources, and some biographical timelines note that details such as birthplace are not consistently documented in early public records. Sizemore’s case gained widespread attention through scholarly reporting and later media adaptations, rather than through ongoing personal public activity.

Notable works and historical projects

• The Three Faces of Eve (book, 1957) — Co-authored by psychiatrists Corbett H. Thigpen and Hervey M. Cleckley, documenting Sizemore’s case and the concept of DID as presented to the public.
• The Three Faces of Eve (film, 1957) — A cinema adaptation portraying the case and its clinical implications; the film popularized DID concepts and featured performances depicting multiple identities.
• Legacy materials and later commentary in psychology and psychiatric literature reflecting on mid-20th‑century case studies and evolving understandings of identity disorders.

News, media coverage and public conversations

As a historical figure whose prominence stemmed from mid‑20th‑century publications, Sizemore herself is not reported to have active public projects or social media presence in recent years. Contemporary discussions about her case typically appear in historical retrospectives on DID, biographical summaries, and discussions of the portrayal of psychiatric disorders in media.

Obituaries and legacy pieces from major outlets around the time of her passing (years after the original publications) summarized her role in bringing attention to dissociative disorders and the ongoing debates within psychiatry about diagnosis, treatment, and patient privacy.

Public profile, impact and legacy
