Jerzy Neyman (1894-1981) was born in Poland and moved to the University of California at Berkeley in 1937. He was one of the founders of the modern theory of statistics. His work on hypothesis testing, confidence intervals and survey sampling has revolutionized both statistical theory and practice.Naming citation (20020128/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
