About the author

Born in Berkeley, Gloucestershire, on May 17, 1749, Edward Jenner trained as a surgeon and physician in England. He is remembered above all for his work on smallpox, a devastating disease that killed and scarred millions.

In 1796, Jenner tested the idea that exposure to cowpox could protect people from smallpox. His published work on vaccination helped spread the practice in Britain and abroad, and the terms vaccine and vaccination grew out of the language he used for cowpox.

Jenner died on January 26, 1823, in his hometown of Berkeley. His legacy reaches far beyond his own era: his smallpox vaccine became the starting point for one of medicine's greatest public health successes.
