Efim Geller
Soviet chess player (1925–1998)
Efim Petrovich Geller (Russian: Ефим Петрович Геллер; Ukrainian: Юхим Петрович Геллер; 8 March 1925 – 17 November 1998) was a Soviet chess player and world-class grandmaster at his peak. He won the Soviet Championship twice (in 1955 and 1979) and was a Candidate for the World Championship on six occasions (1953, 1956, 1962, 1965, 1968, and 1971). He won four Ukrainian SSR Championship titles (in 1950, 1957, 1958, and 1959) and shared first in the 1991 World Seniors' Championship, winning the title outright in 1992.
His wife Oksana was a ballet dancer while his son Alexander was also a chess master. Geller was coach to World Champions Boris Spassky and Anatoly Karpov. He was also an author.
Early life
Geller grew up in Odessa, Soviet Union, and was Jewish. He was a fine basketball player, and earned his doctorate in physical education before specialising in chess. His father was a First Category chess player. His development as a top player was delayed by the inception of World War II.
Geller's first notable result was sixth place in the 1947 Ukrainian SSR Chess Championship at Kiev with 9½/15; the winner was Alexei Sokolsky.

Why this record matters
The phrase “soviet chess player (1925–1998)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Jul 9, 2026. The linked authority identifier is Q352495. VIAF identifies the subject as 29654540. The Library of Congress control number is n80156181. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1925, 1998, 1955 and 1979.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
