If you think today’s health care system is flawed, imagine going in for surgery before anesthesia or antibiotics even existed. Lindsey Fitzharris joins host Krys Boyd to talk about the very beginnings of the modern era of medicine and the pioneers who transformed the practice. Her new book is “The Butchering Art: Joseph Lister’s Quest to Transform the Grisly World of Victorian Medicine” (Farrar, Straus, Giroux).
