(1895–1980; b. London, England; d. Midhurst, Sussex) English mathematical statistician and the only son of Karl Pearson. Egon Pearson went up to Cambridge U in 1914, leaving after a year because of the First World War, when he worked at the Admiralty (his health was too poor for active combat). After the war, he started graduate work in astronomy. In 1921 he joined his father on the faculty at UCL, where he remained (retiring as Head of Department in 1960). Egon's association with Neyman started in 1926 and led to the Neyman–Pearson lemma and the development of a standard approach to hypothesis testing. He was Editor of Biometrika from 1936 to 1965. He was President of the RSS from 1955 to 1957 and was awarded its Guy Medal in Gold in 1955. He was elected FRS in 1966.
