Lev Schnirelmann

Lev Genrikhovich Schnirelmann ( _ru. Лев Генрихович Шнирельман), also Shnirelman, Shnirel'man (born January 2, 1905 in Gomel, died September 24, 1938 in Moscow) was a Soviet mathematician who sought to prove Goldbach's conjecture. In 1931, using the Brun sieve, he proved that any natural number greater than 1 can be written as the sum of not more than 20 prime numbers.

His other fundamental work is joint with Lazar Lyusternik. Together, theydeveloped the "Lyusternik-Schnirelmann category", as it is called now, based on the previous work by Henri Poincaré, David Birkhoff, and Marston Morse. The theory gives a global invariant of spaces, and has led to advances in differential geometry and topology.

According to Pontryagin's memoir, Schnirelmann committed suicide in Moscow. [http://ega-math.narod.ru/LSP/book.htm]
