George Nuttall, American-British bacteriologist (d. 1937)
George Henry Falkiner Nuttall FRS (5 July 1862 – 16 December 1937) was an American-British bacteriologist who contributed much to the knowledge of parasites and of insect carriers of diseases. He made significant, innovative discoveries in immunology, about life under aseptic conditions, in blood chemistry, and about diseases transmitted by arthropods, especially ticks. He carried out investigations into the distribution of Anopheline mosquitoes in England in relation to the previous prevalence of malaria there. With William Welch he identified Clostridium perfringens, the organism responsible for causing gangrene. He also demonstrated the importance of intestinal bacteria in digestion and investigated the bactericidal properties of blood.

He was born in San Francisco to Robert Kennedy Nuttall, a British father, who was a doctor, and Magdalena Parrott, an American mother from California, and was the brother of Zelia Nuttall. He acquired British citizenship in 1900. He gained an M.D. from the University of California in 1884 and a Ph.D. from the University of Göttingen in 1890. In 1899 he moved to England, where he stayed for the rest of his life, and became associated with Cambridge University. In 1906 he was elected the first Quick Professor of Biology at Cambridge (emeritus 1931).

He founded the Molteno Institute for Research in Parasitology in 1921 at the University of Cambridge and was its first Director. Nuttall established and edited the Journal of Hygiene in 1901 and also founded and edited Parasitology in 1908.

He died in 1937 and his ashes were buried in Tunbridge Wells, Kent.His writings include some 150 articles in professional journals.He published:
