British bacteriologist.
After earning a medical degree, he entered the Indian Medical Service and served in the third Anglo-Burmese War (1885). He studied bacteriology in London, then returned to India, where he discovered the plasmodium parasite (cause of malaria ) in the gastrointestinal tract of the Anopheles mosquito in 1897. He used infected and healthy birds to learn its entire life cycle, including its presence in the mosquito's salivary glands, showing how it is transmitted by a bite. He received a 1902 Nobel Prize.
