In 1934, Bill Wilson (1895–1971), a (failed) stockbroker, had an ecstatic experience of a blinding white light while hospitalized for alcoholism, which he associated with the feeling of a “presence” and which gave rise to a vision of a “chain reaction of alcoholics, one carrying this message and these principles to the next.” The vision led to the anonymously authored “Big Book” (Alcoholics Anonymous, 1st edn., 1939) and the Twelve Steps and Twelve Traditions (1953) of Alcoholics Anonymous (AA). This chapter analyzes how Wilson told and retold his story publicly in the context of AA in the 1930s, 1940s, and 1950s. It traces the emergence of a gap between Wilson's personal version of his story and his public account of AA's beginnings.
