Aron Nimzowitsch

Aron Nimzowitsch (born 7 November 1886 in Riga; died 16 March 1935 in Denmark) was a Latvian chess master and theoretician. He made several attempts to win the World Chess Championship without success. His book My System (1925), which effectively launched the Hypermodern movement in chess, remains highly influential.
