Ernst Eduard Kummer (29 January 1810 to 14 May 1893) was a German mathematician. Skilled in applied mathematics, he trained German army officers in ballistics and taught for ten years in a gymnasium, where he inspired the mathematical career of Leopold Kronecker. He was born in Sorau, Brandenburg, then part of Prussia, initially pursued Protestant theology, and was awarded a doctorate by the University of Halle in 1831 for a prize-winning essay on the powers of sines and cosines of multiple arcs. In 1840 he married Ottilie Mendelssohn, a cousin of Felix Mendelssohn. He proved Fermat's Last Theorem for a considerable class of prime exponents, and the Kummer surface, the quotient of a two-dimensional abelian variety by the cyclic group of order two, is named after him.

The conjecture was first made by Ernst Kummer, on 28 December 1849 and 24 April 1853 in letters to Leopold Kronecker, and independently rediscovered around 1920 by Philipp Furtwängler and Harry Vandiver.
