Henry Berthold Mann (27 October 1905, Vienna – 1 February 2000, Tucson)[1] 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 developed the ("Mann-Whitney") U-statistic of nonparametric statistics.[2] Mann published the first mathematical book on the design of experiments: Mann (1949).[3]
