Buchanan Medal

The Buchanan Medal is awarded by the Royal Society "in recognition of distinguished contribution to the medical sciences generally".

The award was created in 1897 from a fund to the memory of London physician Sir George Buchanan (1831–1895).

As a result of the criteria for the medal, most of the winners have been doctors or other medical professionals; an exception was Frederick Warner, an engineer who won the medal in 1982 "for his important role in reducing pollution of the River Thames and of his significant contributions to risk assessment".

The first, Barry Marshall, who was awarded the Buchanan Medal in 1998 "in recognition of his work on discovering the role of Helicobacter pylori as a cause of diseases such as duodenal ulcer, gastric ulcer, gastric cancer and gastritis-associated dyspepsia" and won the Nobel Prize in Physiology or Medicine in 2005.
