EDWARD JENNER (1749-1823) was born in Berkeley, England. He became one of the favorite pupils of John Hunter, but decided against practicing in London. He returned instead to his native village as a country doctor.
In 1798 he published the classic: An inquiry into the causes and effects of the variolae vaccinae, a disease discovered in some of the western counties of England, particularly Gloucestershire, and known by the name of cow pox. This great contribution to medicine was received with some opposition, but Jenner's method was quickly adopted, and brought him world-wide fame. His discovery ranks with the greatest in medicine.
