Henry Mann

Henry Berthold Mann (1905 to 2000) was a professor of mathematics and statistics, born in Vienna to a Jewish family. He earned his doctorate in 1935 at the University of Vienna under Philipp Furtwangler, emigrated to the United States in 1938, and worked at the Ohio State University from 1946 until 1964, later at the University of Wisconsin-Madison and the University of Arizona. In additive number theory he proved the Schnirelmann-Landau conjecture on the density of sumsets in 1942, which became Mann's theorem and earned him the 1946 Cole Prize. In statistics, with his student D. Ransom Whitney he developed the Mann-Whitney U-statistic of nonparametric statistics, and with Abraham Wald he developed the Mann-Wald theorem. His 1949 book on the design of experiments was the first mathematical treatment of the subject. His doctoral students include George Marsaglia and William Yslas Velez.
