Fischer rose to fame when he defeated Boris Spassky in 1972 and later became a controversial figure when he violated international sanctions by traveling to Yugoslavia for a rematch against Spassky in the former Yugoslavia in 1992, Iceland News reported Friday.
The rematch caused Fischer to become wanted by U.S. officials but he renounced his citizenship and was granted status as a citizen of Iceland to avoid deportation.
The chess grandmaster dropped a lawsuit last year that claimed he was tortured in Japan on behalf of the U.S. government.
Fischer was born Robert James Fischer in Chicago on March 9, 1943. He dropped out of high school in New York after becoming the world's youngest grandmaster at age 15.
