Sybil's T was Dr Cornelia Wilbur...a woman. Page 13 of my copy of the book is part of the preface by the author, discussing why she helped with the book...so I can't check the specific reference you are referring too. However, In the book and the newest movie, there is a male psych that Sybil sees very briefly, he refers her to Dr Wilbur, for a "women's issue" (hysteria). There is a problem with this man...but it is mostly Dr Wilbur's problem...he is the main one that denied the existence of DID and made it difficult for Dr Wilbur to present (or even attend) at any professional meetings/conferences.
