 Bill Denies Lois's Request to Write the [Wives] Chapter

There are numerous citations on the internet and elsewhere in print claiming that the Akron Archive contains evidence that Marie Bray, the wife of the Akron A.A. member Walter Bray, wrote a preliminary draft of "To Wives," or at least lent a hand in the writing of that chapter. However, a recent thorough search of the Akron Archives produced no such evidence, nor was the existence of any such evidence known to the long-time archivist who was responsible for creating that collection. It can only be presumed that Marie Bray did actually write a chapter entitled "An Alcoholic's Wife" for the story section of the book. (This was the same story chapter Bill had offered to Anne Smith the previous June, but she had declined to write.)   [A footnote at the bottom of this page states that "Bill Wilson never asked Anne Smith to write "To Wives." - Jim B]

Lois was probably aware that Bill had offered Anne Smith the opportunity to write one of the full length stories for the back of the book and that Anne has refused him. But Lois was not as modest or retiring as Anne Smith. In the almost four years that Bill had been sober, she had "begun to realize how distorted the relationships in families of alcoholics could often be, how important it was for families to understand about alcoholism and to rearrange their thinking." Given all of that, Lois thought writing this chapter was "something she was much better qualified to do" than her husband, so what could be more logical than to assume that Bill would offer her the opportunity to put all of this hard-won knowledge to good use by writing "To Wives" for this book?

But that was an offer Wilson was not willing to make.

According to Lois, when she "shyly suggested" to Bill that she should write this chapter (and perhaps also "The Family Afterward"), he answered with a firm "No," telling her "he thought the book, except for the stories, should all be written in the same style." This is an interesting excuse (and one we shall see Wilson use again later), but it is more than a little self-serving, reflecting Bill's growing sense of ownership and control of the book project as each of the newly finished chapters began to pile up.

However, Bill's reasons for not wanting Lois to write the chapter were, in all likelihood, a bit more complex than this simple-sounding desire for uniformity in style or even his own control issues. For one thing, as he wrote more of the book, Wilson came to appreciate just how difficult it was to write accurately and clearly about the alcoholic condition, and "To Wives" would surely have to address several of these sensitive and complicated questions - not least of which was "What is an alcoholic?" Given that reality, Bill was unwilling to delegate this challenging task to a non-alcoholic, fearing they would almost certainly get the tone wrong or, at the least, offer some unacceptable explanation of alcoholism or some wrong advice on how to handle certain delicate situations involving the newly recovered man.
