Bobby Fischer (March 9, 1943 – January 17, 2008) was an American chess grandmaster and the eleventh World Chess Champion and many consider him the greatest chess player ever. His genius became evident at an early age, as he won "the Game of the Century" at 13 and became the youngest grandmaster ever (at that time) at 15. At just 20 he won the 1963–64 U.S. Championship with the only perfect score in the history of the tournament (11/11). He became reclusive after losing his world champion title. In 1992 he decided to play again and won an unofficial rematch against Spassky, which, however, caused problems because the match took place in Yugoslavia, which at that time was under a United Nations Embargo. He lived the rest of his life as an émigré. Fischer was not only an exceptional chess player, but also made great contributions to chess playing in general, like a modified chess timing system patented in the 1990s and a new variant of chess named Fischerandom (today called "Chess960"). Fischer is mentioned as likely autistic in Unstrange Minds: Remapping the World of Autism by Roy Grinker as well as other sources (for example this article).
