Svetozar Gligorić, Serbian chess player and theoretician (b. 1923)
Svetozar Gligorić (Serbian Cyrillic: Светозар Глигорић, 2 February 1923 – 14 August 2012) was a Serbian and Yugoslav chess grandmaster and musician. He won the championship of Yugoslavia a record twelve times, and is considered the best player ever from Serbia. In 1958, he was declared the best athlete of Yugoslavia.

In the 1950s and 1960s, Gligorić was one of the top players in the world. He was also among the world's most popular players, owing to his globe-trotting tournament schedule and a particularly engaging personality, reflected in the title of his autobiography, I Play Against Pieces (i.e., without hostility toward the opponent, and not differently against different players for "psychological" reasons; playing "the board and not the man").
