[Graphic Content] Dr. Schillace is a medical historian, an editor, and the author of the brand new book titled Mr. Humble and Dr. Butcher, the real life story of Dr. Robert White, the neurosurgeon who successfully transplanted a monkey’s head onto another monkey’s body. It’s an utterly fascinating page-turner – and it’s a little disturbing as well. So let this be a warning: today’s show might be upsetting to some people, so proceed with caution. Follow Dr. Schillace on Twitter here.
