an English physician who made seminal contributions in anatomy and physiology. He was the first known to describe completely and in detail the systemic circulation and properties of blood being pumped to the brain and body by the heart. Published in 1628 in the city of Frankfurt (host to an annual book fair that Harvey knew would allow immediate dispersion of his work), 72 page Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus contains the matured account of the circulation of the blood. Harvey's other major work was Exercitationes de generatione animalium, published in 1651. He had been working on it for many years but might never have finished it without the encouragement of his friend George Ent.
