Bill Wilson (1895 - 1971), also known as Bill W., was the co-founder of Alcoholics Anonymous (AA), a group dedicated to helping alcoholics break their habit. AA has over two million members belonging to 100k groups of alcoholics helping other alcoholics achieve and maintain sobriety. In 1999 Time listed him as "Bill W.: The Healer" in the Time 100: The Most Important People of the Century. In this recording, Wilson gives a public lecture on the history of AA and his experience in 1934 when he was visited by old drinking companion Ebby Thacher, who had been sober for several weeks under the guidance of the evangelical Christian Oxford Group.
