Egon Sharpe Pearson, FRS, 11 August 1895 - 12 June 1980

Egon Pearson, the only son of Karl Pearson, the founder of modern
statistics, entered his father's Department of Applied Statistics
(DAS) at University College London in 1921 and later collaborated
with both W.S. Gosset and Jerzy Neyman, with the latter 10-year
collaboration resulting in the collection of principles representing
a general approach to statistical hypothesis testing often known as
the Neyman-Pearson theory, perhaps peaking in 1933 with the Neyman-
Pearson Lemma, as well as those Type I and Type II errors. [BTW, he
was the developer of the likelihood-ratio principle, which is the
impetus behind that second and more common proof being offered by me
that the common chi-square test stat has such a distribution --- for
anyone who wants it, then let me know --- off-List --- and a copy
will be forwarded to you. (For the most part, those requesting such
thus far have been sent the first proof, unless requesting "both".)]

ESP became head of DAS upon KP's retirement in 1933 (they were known
locally as KP and ESP), also becoming managing editor of Biometrika
upon his father's death in 1936. About twenty years later he became
President of the Royal Statistical Society, and eventually a Fellow
of the RSS.

A book by ESP published posthumously (in 1990) on Gosset and titled
"'Gosset': A Statistical Biography of William Sealy Gosset" is
largely made up of correspondence ESP had with Gosset, who the
book's Editors R.L. Plackett and G.A. Barnard write was not only a
"distinguished statistician" but "whose attractive personality
shone out in everything that he did."

For more, see the good two-page essay on Pearson that appeared in
the May 1981 issue of TAS, which was reprinted in a special issue
of the Amstat News in Sept 2004. If interested, then here's the
