Flora Rheta Schreiber

Flora Rheta Schreiber (April 24, 1918 – November 3, 1988), an American journalist, was the author of the 1973 bestseller Sybil, the story of a woman (identified years later as Shirley Ardell Mason) who suffered from dissociative identity disorder. Ms. Schreiber was an English instructor at the John Jay College of Criminal Justice. Her earlier book was Your Child's Speech. Her last book The Shoemaker was the true story of a mass murderer who suffered from schizophrenia.

A recent book, "SYBIL in her own words: The Untold Story of Shirley Mason, Her Multiple Personalities and Paintings", by Dr. Patrick Suraci contains interviews with Sybil/Shirley Mason after her integration. The book also includes color reproductions of paintings made by 5 of Sybil's alternate personalities. In Chapter 19 (The Controversy over Sybil), Dr. Suraci gives evidence which refutes the claims by critics of Sybil's case of Multiple Personality Disorder.
