She conjures up early operating theaters no place for the squeamish and surgeons, who, working before anesthesia, were lauded for their speed and brute strength. These pioneers knew that the aftermath of surgery was often more dangerous than patients' afflictions, and they were baffled by the persistent infections that kept mortality rates stubbornly high. At a time when surgery couldn't have been more hazardous, an unlikely figure stepped forward- a young, melancholy Quaker surgeon named Joseph Lister, who would solve the riddle and change the course of history. Fitzharris dramatically reconstructs Lister's career path to his audacious claim that germs were the source of all infection and could be countered by a sterilizing agent applied to wounds.
