John Warren (1753-1815): American surgeon, patriot and Harvard Medical School founder.

Dr John Warren was educated in the medical apprenticeship tradition of mid-18th century Boston, Massachusetts. As a surgeon in the American Continental Army he honed not only his surgical but also his teaching skills by providing continuing medical education to his colleagues in Boston's military hospital. Warren became a driving force in post-war Boston medicine. His organizational talents, zeal for science and vision for Massachusetts medicine led to the creation of Harvard Medical School.
