Sir Ronald Ross, KCB, FRS (13 May 1857 – 16 September 1932), was a British medical doctor who received the Nobel Prize for Physiology or Medicine in 1902 for his work on malaria, becoming the first British Nobel laureate, and the first born outside of Europe. His discovery of the malarial parasite in the gastrointestinal tract of mosquito led to the realisation that malaria was transmitted by mosquitoes, and laid the foundation for combating the disease.
