Marion Tinsley

Marion Franklin Tinsley was an American mathematician and checkers player. He is considered to be the greatest checkers player who ever lived. Tinsley was world champion 1955–1958 and 1975–1991 and never lost a world championship match, and lost only seven games from 1950 until his death in 1995. He withdrew from championship play during the years 1958–1975, relinquishing the title during that time. It was said that Tinsley was "to checkers what Leonardo da Vinci was to science, what Michelangelo was to art and what Beethoven was to music."
