Jerzy Neyman

Jerzy Spława-Neyman (also known as Jerzy Neyman; April 16, 1894 – August 5, 1981) was a Polish mathematician and statistician. He made major contributions to the development of modern statistical theory. Neyman introduced the modern concept of a confidence interval into statistical hypothesis testing and, with Egon Pearson, revised Ronald Fisher's null hypothesis testing. Neyman allocation, an optimal strategy for choosing sample sizes in stratified sampling, is named for him. He spent the first part of his professional career at various institutions in Warsaw, Poland, and then at University College London, and the second part at the University of California, Berkeley where he founded and developed one of the world’s leading centres of mathematical statistics. Neyman was the recipient of many awards during his career including the Guy Medal, the Newcomb Cleveland Prize, and the National Medal of Science. He was a member of the Polish Academy of Sciences, the Polish Mathematical Society, the National Academy of Sciences, and Fellow of the Royal Society.
