Ignac Semmelweis is remembered for the now-commonplace notion that doctors must wash their hands before examining patients. In mid-nineteenth century Vienna, however, this was a subversive idea. With deaths from childbed fever exploding, Semmelweis discovered that doctors themselves were spreading the disease. While his simple reforms worked immediately, they also threatened the medical establishment and so undid the passionate but self-destructive Semmelweis that he failed to overturn the status quo, leaving it to later medical giants - Pasteur, Lister, and Koch - to establish conclusively the germ theory of disease.

The Doctors' Plague is a revealing narrative of one of the key turning points in medical history.
