José Raúl Capablanca y Graupera (19 November 1888 – 8 March 1942) was a Cuban chess player who was world chess champion from 1921 to 1927. One of the greatest players of all time, he was renowned for his exceptional endgame skill and speed of play. Due to his achievements in the chess world, mastery over the board and his relatively simple style of play he was nicknamed the "Human Chess Machine".

José Raúl Capablanca, the second surviving son of a Spanish army officer, was born in Havana on November 19, 1888. According to Capablanca, he learned the rules of the game at the age of four by watching his father play, pointed out an illegal move by his father, and then beat his father twice. At the age of eight he was taken to Havana Chess Club, which had hosted many important contests, but on the advice of a doctor he was not allowed to play frequently. Between November and December 1901, he narrowly beat the Cuban Chess Champion, Juan Corzo, in a match. However in April 1902 he only came fourth out of six in the National Championship, losing both his games against Corzo. In 1905 Capablanca passed with ease the entrance examinations for Columbia University in New York City, where he wished to play for Columbia's strong baseball team, and soon was selected as shortstop on the freshman team. In the same year he joined the Manhattan Chess Club, and was soon recognized as the club's strongest player. He was particularly dominant in rapid chess, winning a tournament ahead of the reigning World Chess Champion, Emanuel Lasker, in 1906. In 1908 he left the university to concentrate on chess.
