Emanuel Sperner was a German mathematician, born on 9 December 1905 and died on 31 January 1980, best known for two theorems. He was born in Waltdorf, near Neisse in Upper Silesia, now Nysa in Poland, studied at Hamburg University where his advisor was Wilhelm Blaschke, was appointed professor in Konigsberg in 1934, and held posts in a number of universities until 1974. Sperner's theorem, from 1928, says that the size of an antichain in the power set of an n-set is at most the middle binomial coefficient, and Sperner's lemma, also from 1928, concerns colorings of triangulations.
