Dr. John Brinkley's Goatee?

In private, Dr. Brinkley had a habit of calling his patients old fools, especially while drinking. But in public, he was the picture of the genteel man of medicine. According to the book, Charlaton, he only had a wavering conception of how to perform his own signature surgery. He passed off more and more of the work to assistance with medical credentials even wispier than his own. As a result, dozens of patients died over the years or were permanently maimed.
