Furor: Hitler and the Frog describes the tribulations and training of a neurologist, the learning of how disease affects the brain, how it alters thinking, mood, and behavior. As a Jew, growing up in the 1940s and 1950s in Brooklyn, I was fascinated by Adolf Hitler: Why did he hate the Jews? Why did he hate me? My fascination with Hitler and the Nazis was carried into college where I majored in German history. In 1959 I entered the New York University School of Medicine and studied at Bellevue Hospital. While studying neurology, I forgot bout Adolf Hitler. Then in the late 1970s reports began to surface that Hitler had Parkinson disease. I became fascinated with whether Hitler indeed had Parkinson disease. My fascination with Hitleras Parkinson disease culminated in my being asked to review the Hitler Diaries in 1983. I was one of the experts who testified that the diaries were forgeries. The basis for writing Furor: Hitler and the Frog came when someone asked me what I would do if I, as a Parkinson expert, were asked to treat Adolf Hitler. As a Parkinson expert I have treated some notorious people, people who, were I not an expert, I would never want to see. Disease humbles everyone even awful people. This is what I try to convey in the novel.
