This is the first historical dictionary of psychiatry. It covers the subject from autism to Vienna, and includes the key concepts, individuals, places, and institutions that have shaped the evolution of psychiatry and the neurosciences. An introduction puts broad trends and international differences in context, and there is an extensive bibliography for further reading. Each entry gives the main dates, themes, and personalities involved in the unfolding of the topic. Longer entries describe the evolution of such subjects as depression, schizophrenia, and psychotherapy.
