Léon Wurmser (German: [ˈvʊrmzɐ]; born 31 January 1931, Zurich) is an internationally known psychoanalyst, now Clinical Professor of Psychiatry at West Virginia University and a training and supervising analyst of the New York Freudian Society. He was formerly Professor of Psychiatry and Director of the Alcohol and Drug Abuse Program at University of Maryland, Baltimore. Wurmser was born in 1931 in Zurich, Switzerland. He currently resides in Towson, Maryland, where he maintains a private practice. He supervises many colleagues in the United States and in Europe in psychoanalysis and psychotherapy. He lectures widely throughout Europe and is an honorary member of a number of psychoanalytic societies in Germany and in Austria.
Wurmser has authored more than 350 scientific papers, 15 books, and numerous book chapters and essays. His works deal with issues of masochism and depression, focusing on problems of shame, guilt, resentment, and the "archaic superego," both in the individual and in culture, religion, and history. He has written a number of papers and one book on Judaism: "The World of Ideas and Values of Judaism: A Psychoanalytic View" (published in German). He also deals with the understanding and treatment of drug addicts, drawing on many years' experience running comprehensive treatment programs for addicts. In recent years, he has published several papers and one book on jealousy and envy, in partnership with German psychoananalyst Dr. Heidrun Jarass.
Wurmser's approach to psychoanalysis is Freudian. His major works, published in English and German, include the oft-cited "The Mask Of Shame," published in 1981 and frequently reprinted; "The Hidden Dimension" (1978) on the psychodynamics of drug addiction; "The Power of the Inner Judge" (2000); and "Torment Me But Don't Abandon Me" (2007).
Wurmser has also been the recipient of several awards in his career. In 2004, he was awarded the Journal of the American Psychoanalytic Association Journal Prize  for a paper titled "Psychoanalytic Reflections on 9/11, Terrorism and Genocidal Prejudice: Roots and Sequels."
