William Duncan Silkworth
William Duncan Silkworth, M.D., (1873-1951) was an American medical doctor and specialist in the treatment of alcoholism. He was Director of the Charles B. Towns Hospital for Drug and Alcohol Addictions in New York City in the 1930s, during which time Bill Wilson, a future co-founder of the mutual-help movement Alcoholics Anonymous (A.A.), was admitted on four separate occasions for alcoholism. Silkworth had a profound influence on Wilson and encouraged him to realize that alcoholism was more than just an issue of moral weakness. He introduced Wilson to the idea that alcoholism had a pathological, disease-like basis.
William Silkworth wrote the letters in the chapter titled "The Doctor's Opinion" in the book Alcoholics Anonymous.
