I am guessing it was first promulgated as a memorial to Dr. Bob.
A Manual for
Alcoholics Anonymous
From AA Group No. 1, Akron, Ohio, 1940
Dr. Bob's Home Group
(Editor's Note, 1997: Dr. Bob probably wrote or heavily influenced the writing and distribution of this pamphlet. Dr. Bob was the Prince of 12 Steppers, from the day he achieved permanent sobriety, June 10, 1935, the founding date of Alcoholics Anonymous, until his death, November 16, 1950 , carrying the message of A.A. to well over 5000 men and women alcoholics, and to all these he gave his medical services without thought of charge.)
