Harry M. Tiebout, M.D. was a Brooklyn-born psychiatrist who became one of the most important figures in the history of addiction medicine — not because he founded a program, but because he dared to take AA seriously when the medical establishment would not.
Beginning in 1939, Tiebout observed AA meetings and became convinced that what he was witnessing — the phenomenon of surrender and spiritual awakening — held the key to understanding why some alcoholics recovered and others did not. He spent the rest of his career translating that observation into clinical language that the medical world could hear.
He served on the Board of Trustees of Alcoholics Anonymous from 1957 to 1966 and was president of the National Council on Alcoholism from 1951 to 1953. He was the first psychiatrist to put his stamp of approval on the AA Twelve Step program as a legitimate treatment for alcoholism.
