In this bonus episode, we welcome a new member to the Legends of Surgery team, Dr. David Simon, a general surgery resident at the University of Chicago currently researching surgical education at the University of Pennsylvania. He wrote this episode, which covers the history of the discovery of the adrenal glands, the efforts made to understand its function, and, of course, the pioneers who first operated on these glands. We'll also learn how some of the diseases produced by the adrenals have effected history, and in particular a famous American president, at a very inopportune time in history!
