William Harvey

Born in Folkestone, England, in 1578, William Harvey studied at Cambridge and later at the University of Padua in Italy, one of Europe’s leading medical schools. He went on to build a distinguished career in London as a physician and also served as doctor to King James I and King Charles I.

Harvey is remembered above all for his 1628 book on the motion of the heart and blood, where he argued that blood moves in a continuous circuit through the body, driven by the pumping action of the heart. At a time when older medical ideas still dominated, that conclusion was remarkable because it rested on anatomy, careful observation, and experiment.

He also wrote on reproduction and development, extending his curiosity well beyond the circulation of blood. By the time of his death in 1657, Harvey had become one of the key figures in the history of science and medicine, admired for helping make medicine more evidence-based.
