Richard Peto
1943
British statistician and epidemiologist at Oxford, best known for large-scale work on the health effects of smoking and on cancer trial methodology. In a 1975 paper on cancer and ageing in mice and men he noted that cancer incidence does not scale with body size across species — the observation later named Peto's paradox.
