Richard Lower (1631-1691) was an Cornish physician who played an important part in the development of medical science.

Lower was born in Cornwall and studied at Oxford, where he met Thomas Willis, founder of the Royal Society. He followed Willis to London, where he carried out research, some in partnership with Robert Hooke. His major work, Tractatus de Corde (1669) was concerned with the workings of the heart and lungs, and he experimented with blood transfusion.
