Sir Leonard Rogers FRS (1868–1962) was a founder member of the Royal Society of Tropical Medicine and Hygiene, and its President from 1933 to 1935. Rogers had a wide range of interests in tropical medicine, from the study of kala-azar epidemics to snake venoms, but is best known for pioneering the treatment of cholera with hypertonic saline, which has saved a multitude of lives. Rogers was one of the pioneers in setting up the Calcutta School of Tropical Medicine in India. The foundation stone was laid on 24 February, 1914 by Lord Carmichael, the then Governor of Bengal. Accordingly, the hospital section of the institute is known as Carmichael Hospital for Tropical Diseases.
