Robert Francis Furchgott was an American pharmacologist who shared the 1998 Nobel Prize in Physiology or Medicine for discovering that nitric oxide functions as a signaling molecule in the cardiovascular system. Their combined work revealed an entirely new mechanism by which blood vessels in the body relax and widen. Nerves and hormones are known as signal carriers, but this discovery was an entirely new signaling principle in a biological system.
