German surgeon who advanced the emerging profession of surgery by stopping the bleeding associated with amputation of limbs by applying pressure to the limbs and blood vessels. Gersdorff also published a book on surgery in which he first pictured an amputation of a leg. At that time the surgeon would wrap the wound on either side of the limb to be amputated and then cover the stump with the bladder of a bull or hog.
