Aubrey J. Kempner

Aubrey J. Kempner ( born September 22, 1880 in Greater London, ( England), † November 18, 1973 in Boulder (Colorado) ) was an English, active in the United States mathematician.

Aubrey Kempner in 1911 received his doctorate with a dissertation About the Waring problem and some generalizations with Edmund Landau at the University of Göttingen. Then he went to the USA, first at the University of Illinois and from 1925 to the University of Colorado at Boulder, where he remained until 1949 and presided from 1944 to 1949 the mathematics department. From 1950 he also taught at the Colorado School of Medicine and the National Institute of Standards and Technology in Boulder.

Kempner's main areas of work were number theory and algebra with a focus on polynomial equations. To him, the Kempner Colloquium was established at the Mathematics Department of the University of Colorado at Boulder in honor. The Kempner series whose convergence he showed, are connected with his name. From 1937 to 1938 he was president of the Mathematical Association of America.
