Henry Mann

Henry Berthold Mann was a professor of mathematics and statistics at the Ohio State University. Mann proved the Schnirelmann-Landau conjecture in number theory, and as a result earned the 1946 Cole Prize. He and his student D. Ransom Whitney developed the ("Mann-Whitney") U-statistic of nonparametric statistics. Mann published the first mathematical book on the design of experiments: Mann (1949).

Early life of a number theorist

Born in Vienna, Austria-Hungary, to a Jewish family, Mann earned his Ph.D. degree in mathematics in 1935 from the University of Vienna under the supervision of Philipp Furtwängler. Mann immigrated to the United States in 1938, and lived in New York, supporting himself by tutoring students. By doing so he established Mann's theorem and earned the 1946 Cole Prize. ==Statistics==

Statistics

In 1942 the Carnegie Foundation awarded Mann a fellowship to learn statistics while assisting the operations research group of Harold Hotelling at Columbia University. His group also supported Abraham Wald, and Wald and Mann collaborated on several papers. In statistics, Mann is known for the ("Mann–Whitney") U-statistic and its associated hypothesis test for nonparametric statistics. Collaborating with Wald, Mann developed the Mann–Wald theorem of asymptotic statistics and econometrics. According to Denis Conniffe: ==Later life==

Later life

In 1946 Mann returned to Ohio State University, where he served as a professor of mathematics until his retirement in 1964. Mann then became a professor at the U.S. Army's Mathematics Research Center at the University of Wisconsin–Madison 1964–1971. Mann was professor at the University of Arizona from 1971 to 1975. His doctoral students include George Marsaglia and William Yslas Vélez. ==Publications==
