Sidney Siegel

Sidney Siegel (4 January 1916 in New York City – 29 November 1961) was an American psychologist who became especially well known for his work in popularising non-parametric statistics for use in the behavioural sciences. He was a co-developer of the statistical test known as the Siegel–Tukey test.
Siegel completed a Ph.D. in Psychology in 1953 at Stanford University. Except for a year spent at the Center for Advanced Study in the Behavioral Sciences at Stanford, he thereafter taught at Pennsylvania State University, until his death in November 1961 of a coronary thrombosis.
His parents, Jacob and Rebecca Siegel, were Jewish immigrants from Romania.
