Who wrote the Chapter 9, in the Big Book, "The Family Afterwards"?

Like most of the book it was a group effort with Bill W. acting as an editor.

Also remember that Jim S. (Traveler, Editor, Scholar - 1st Edition) edited all of the Akron stories (except Dr. Bob's) for the book. Several of these original stories pre-editing are stored at the Stepping Stones Archives. We don't know if Jim got paid for his editing expertise and work. There was also another writer who worked on the book shortening it prior to publication -- Professor Tom Uzzel, New York. His payment, if any, is also unknown.
