Bobby Fischer

Robert James "Bobby" Fischer (March 9, 1943 – January 17, 2008) was an American chess Grandmaster, and the eleventh World Chess Champion. He is widely considered one of the greatest chess players of all time. Later in life he renounced his US citizenship and became an Icelandic citizen.
Fischer's achievements are legendary. At 13, he won a brilliancy that became known as the Game of the Century. Starting at age 14, he played in eight United States Championships, winning each by at least a point. At 15½, he became both the youngest Grandmaster and the youngest Candidate for the World Championship up until that time. He won the 1963-64 US championship 11-0, the only perfect score in the history of the tournament. In the early 1970s he became the most dominant player in modern history—winning the 1970 Interzonal by a record 3½-point margin and winning 20 consecutive games, including two unprecedented 6-0 sweeps in the Candidates Matches. In 1972, he wrested the World Championship from Boris Spassky of the Soviet Union in a match held in Reykjavík, Iceland that was widely publicized as a Cold War battle.
