DeWitt Director

"Welcome to the DeWitt Wallace Institute of Psychiatry! For six decades, we have been uniquely devoted to furthering the understanding of mental health and illness through the study of the humanities. Once an 'insider’s secret', we are delighted to use this platform to make available lectures, seminars, fact sheets, and holdings of our extraordinary Oskar Diethelm Library, as we build toward a brighter future."

- George J. Makari, M.D.
