A fascinating new book links art, the mentally ill and Adolf Hitler. It tells the story of how modern art was originally inspired by the work of psychiatric patients and how Hitler – twice rejected from art school – turned first on modern artists and later on those who had inspired them. The Nazis murdered thousands of psychiatric patients, in a chilling forerunner of the Holocaust. The book is entitled "The Gallery of Miracles and Madness: Insanity, Modernism, and Hitler's War on Art". Its author Charlie English joined us on Perspective to tell us more.
