Sir Almroth Wright

Died 30 Apr 1947 at age 85 (born 10 Aug 1861).Sir Almroth Edward Wright was an English bacteriologist who developed an immunization against typhoid fever that protected British soldiers in WW I, saving lives from infection. It was the result of his work beginning in 1892, while professor of pathology at the Army Medical School, using typhoid bacilli killed by heat. Tests on over 3,000 soldiers in India were followed by its successful use during the South African (Boer) War. He was noted for creating autogenous vaccines, prepared from the bacteria harboured by the patient. Wright also developed vaccines against enteric tuberculosis and pneumonia and contributed to the study of opsonins (blood enzymes that make bacteria more susceptible to phagocytosis by white cells.)«
