Conrad W. Baars, MD (1919-1981) was a Dutch-born American citizen who practiced psychiatry in the United States from 1946 until his death. Educated at Oxford University and the University of Amsterdam Medical School, Dr. Baars served in the anti-Nazi underground in Belgium, France, and the Netherlands during World War II. Captured by the Nazis, he spent one and a half years in Buchenwald concentration camp. He emigrated to the United States following the war, and discovered Dutch psychiatrist Dr. Anna A. Terruwe's work on energy and frustration neuroses in the mid-1950's. He further developed and promoted this work throughout the rest of his psychiatric career. His books include Born Only Once, Feeling and Healing Your Emotions, and I Will Give Them a New Heart: Reflections on the Priesthood and the Renewal of the Church. Drs. Baars and Terruwe coauthored Healing the Unaffirmed. His autobiography, Doctor of the Heart, details much of his experience in Buchenwald.Drs. Baars and Terruwe coauthored Healing the Unaffirmed.
