Sir Leonard Rogers KCSI CIE FRS FRCP FRCS[3][4] (18 January 1868 – 16 September 1962) was a founder member of the Royal Society of Tropical Medicine and Hygiene, and its President from 1933 to 1935.[1][5]


Rogers had a wide range of interests in tropical medicine, from the study of kala-azar epidemics to sea snake venoms, but is best known for pioneering the treatment of cholera with hypertonic saline, which has saved a multitude of lives. He also championed Indian chaulmoogra oil as a treatment for Hansen's disease (leprosy).

Rogers was one of the pioneers in setting up the Calcutta School of Tropical Medicine (CSTM) in Calcutta, India.[6][7] In 1929, Rogers was awarded the Cameron Prize for Therapeutics of the University of Edinburgh.

He was president of the 1919 session of the Indian Science Congress.
