Efim Bogoljubow

Efim Dimitrijewitsch Bogoljubow was a Russian-born German chess grandmaster, born in 1889 and dead in 1952. He played two matches for the World Chess Championship against Alexander Alekhine, losing 15.5 to 9.5 in 1929 and 15.5 to 10.5 in 1934. He won consecutive Soviet championships in 1924 and 1925, emigrated to Germany in 1926 and won the first German championship in 1933, which made him the only player to hold both titles. FIDE awarded him the grandmaster title in 1951, after first withholding it for political reasons, and the Bogo-Indian Defence is named after him. He was also known for the remark that when he had White he won because he was White, and when he had Black he won because he was Bogoljubow.
