Richard Doll, English physiologist and epidemiologist (b. 1912)
Sir William Richard Shaboe Doll (28 October 1912 – 24 July 2005) was a British physician who became an epidemiologist in the mid-20th century and made important contributions to that discipline. He was a pioneer in research linking smoking to health problems. With Ernst Wynder, Bradford Hill and Evarts Graham, he was credited with being the first to prove that smoking increased the risk of lung cancer and heart disease. (German studies had suggested a link as early as the 1920s but were forgotten or ignored until the 1990s.)

He also carried out pioneering work on the relationship between radiation and leukaemia as well as that between asbestos and lung cancer, and alcohol and breast cancer. On 28 June 2012, he was the subject of an episode of The New Elizabethans, a series broadcast on BBC Radio Four to mark the Diamond Jubilee of Queen Elizabeth II, dealing with 60 public figures from her reign.
