Bill W.
AA cofounder Bill Wilson (1895–1971) was the chief voice and writer behind Alcoholics Anonymous—often called “The Big Book”—on which he collaborated with many figures, including his wife and intellectual partner, Lois Wilson (1891–1988); his AA cofounder, Bob Smith (1879–1950); pioneering AA member Henry Parkhurst (1895–1954); and a wide range of early AAs who contributed stories and strategies.
