Henry Bernard Davis Kettlewell (24 February 1907 – 11 May 1979) was a British geneticist, lepidopterist and medical doctor, who performed research on the influence of industrial melanism on peppered moth (Biston betularia) colouration, showing why moths are darker in polluted areas. This experiment is cited as a classic example of natural selection. After live video record of the experiment with Niko Tinbergen, Sewall Wright called the study as "the clearest case in which a conspicuous evolutionary process has actually been observed."
Kettlewell was born in Howden, Yorkshire, and educated at Charterhouse School. During 1926 he studied medicine and zoology at Gonville and Caius College, Cambridge. During 1929 he began clinical training at St Bartholomew's Hospital, London, then during 1935 joined a general medical practice in Cranleigh, Surrey. He also worked as an anesthetist at St. Luke's Hospital, Guildford. During World War II, from 1939 to 1945, he worked for the Emergency Medical Service at Woking War Hospital.
He emigrated to South Africa during 1949, and from then until 1954 was a researcher at the International Locust Control Centre at Cape Town University, investigating methods of locust control and going on expeditions to the Kalahari Desert, the Knysna Forest, the Belgian Congo, and Mozambique.
