American-born chess master Bobby Fischer has died of undisclosed causes at the age of 64.
After years of Russian domination, Fischer became the first American chess champion in 1972 when he defeated Boris Spassky of the Soviet Union in a legendary match. After the victory, Fischer became reclusive. He emerged to defeat Spassky again in 1992, but he never regained his championship.
Fischer finished out his life as a citizen of Iceland. He died in a hospital in the capital city of Reykjavik.
