CELEBRITY OF THE MONTH
William Harvey
439th Birthday, (1 April 1578 – 3 June 1657)
English physician; Inventor of blood circulation

Harvey was an English physician who was the first to describe accurately how blood was pumped around the body by the heart. He was born in Folkestone, Kent on 1 April 1578. He made the momentous medical discovery that the flow of blood must be continuous and that its flow must be in one direction only. This discovery sealed his place in the history of medicine. He learned about the human body by dissection and anatomical observation. He focused much of his research on the mechanics of blood flow in the human body. Most physicians of the time felt that the lungs were responsible for moving the blood around throughout the body. Harvey questioned these beliefs and his questions directed his life-long scientific investigations. His Direct observation of the heartbeat of living animals showed that the ventricles contracted together, dispelling Galen's theory that blood was forced from one ventricle to the other. Dissection of the septum of the heart showed that it contained arteries and veins, not perforations.
