She was also treated with prejudice for being one of few women in her field.Dr. Wilbur made a case study of Sybil, and, as a result, Multiple Personality Disorder eventually became accepted as a viable psychiatric evaluation.Dr. Wilbur died in 1992. Shirley Mason died a recluse in 1998; her belongings were auctioned off after her death, and, as a result, it was discovered that Shirley Mason was the woman the rest of the world knew as Sybil.
