William Harvey
William Harvey (1 April 1578 – 3 June 1657) was an English physician. 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, though earlier writers, such as Jacques Dubois, had provided precursors of the theory. After his death the William Harvey Hospital was constructed in the town of Ashford, several miles from his birthplace of Folkestone.
