William Harvey

Born in Folkestone, England, in 1578, William Harvey studied at Cambridge and then at the University of Padua, one of Europe's leading medical schools. He later built a distinguished career in London as a physician, serving at St Bartholomew's Hospital and also treating English kings.

Harvey is remembered above all for demonstrating that the heart acts as a pump and that blood moves in a continuous circuit through the body. Published in 1628, his findings challenged older medical beliefs and were backed by observation, dissection, and experiment in a way that felt strikingly modern.

He also wrote on animal generation and embryo development, showing that his curiosity reached well beyond the circulation of blood. Even centuries later, he stands out as a physician who changed how people studied the body: not by repeating tradition, but by testing what he could see.
