For over 25 years, he was the leading national proponent of the view that alcoholism is a primary neuropsychological disorder, not a symptom or consequence of psychosocial “risk factors,” as commonly believed. It was his Position Paper, written for the Washington State Council on Alcoholism in 1972, that provided the rationale for moving alcoholism out of mental health jurisdiction in Washington State and elsewhere. He is best known as the author, with Katherine Ketcham, of the best seller “UNDER THE INFLUENCE,” Bantam Books, New York, 1983.
