The International Chess Federation or World Chess Federation, commonly referred to by its French acronym FIDE, is an international organization based in Switzerland that connects the various national chess federations and acts as the governing body of international chess competition. FIDE was founded in Paris, France, on July 20, 1924. Its motto is Gens una sumus, Latin for 'We are one Family'. In 1999, FIDE was recognized by the International Olympic Committee (IOC). As of December 21, 2023, there are 201 member federations of FIDE.

The sixth World Chess Champion, he also worked as an electrical engineer and computer scientist and was a pioneer in computer chess. He also had a mathematics degree (honorary).
Paul Keres was an Estonian chess grandmaster and chess writer. He was among the world's top players from the mid-1930s to the mid-1960s, and narrowly missed a chance at a World Chess Championship match on five occasions. As Estonia was repeatedly invaded and occupied during World War II, Keres was forced by the circumstances to represent the Soviet Union and Nazi Germany (1941–44) in international tournaments.
Alexander Alexandrovich Kotov was a Soviet chess grandmaster and author. He was a Soviet chess champion, a two-time world title Candidate, and a prolific writer on the subject of chess. Kotov served in high posts in the Soviet Chess Federation, and wrote most of his books during the Cold War. The importance and breadth of Kotov's work rank him among the all-time greats in this field.
Reuben C. Fine was an American chess player, psychologist, university professor, and author of many books on both chess and psychology. He was one of the strongest chess players in the world from the mid-1930s until his retirement from chess in 1951. He was granted the title of International Grandmaster by FIDE in 1950, when titles were introduced.
Sultan Khan was a British Indian Punjabi chess player, and later a citizen of Pakistan, who is thought to have been the strongest chess master of his time from Asia. The son of a Muslim landlord and preacher, Khan travelled with Colonel Nawab Sir Umar Hayat Khan, to Britain, where he took the chess world by storm. In an international chess career of less than five years (1929–33), he won the British Championship three times in four attempts, and had tournament and match results that placed him among the top ten players in the world. Sir Umar then brought him back to his homeland, where he gave up chess and returned to cultivate his ancestral farmlands in the area which became Pakistan. He lived there before dying in his sixties in the city of Sargodha. David Hooper and Kenneth Whyld have called him "perhaps the greatest natural player of modern times". In 2024 FIDE posthumously awarded him the title of Honorary Grandmaster.
Salomon Mikhailovich Flohr was a Czechoslovak and Soviet chess player and writer. He was among the first recipients of the title International Grandmaster from FIDE in 1950. Flohr dominated many tournaments of the pre-World War II years, and by the late 1930s was considered a contender for the World Championship. However, his patient, positional style was overtaken by the sharper, more tactical methods of the younger Soviet echelon after World War II.
Vladimirs Petrovs was a Latvian Russian chess player.
Several methods have been suggested for comparing the greatest chess players in history. There is agreement on a statistical system to rate the strengths of current players, called the Elo system, but disagreement about methods used to compare players from different generations who never competed against each other.
Andor Arnoldovich Lilienthal was a Hungarian and Soviet chess player. In his long career, he played against ten male and female world champions, beating Emanuel Lasker, José Raúl Capablanca, Alexander Alekhine, Max Euwe, Mikhail Botvinnik, Vasily Smyslov, and Vera Menchik.
