Tigran Petrosian (1929–1984)
Born 1929 CE, died 1984 CE.
Tigran Vardani Petrosian (Armenian: Տիգրան Վարդանի Պետրոսյան; Russian: Тигран Вартанович Петросян; 17 June 1929 – 13 August 1984) was a Soviet-Armenian chess grandmaster. The ninth World Chess Champion from 1963 to 1969, he was nicknamed "Iron Tigran" due to his almost-impenetrable defensive playing style, which emphasized safety above all else. Petrosian is often credited with popularizing chess in Armenia. Petrosian was a candidate for the World Chess Championship on eight occasions (1953, 1956, 1959, 1962, 1971, 1974, 1977 and 1980). He won the World Championship in 1963 (against Mikhail Botvinnik), successfully defended it in 1966 (against Boris Spassky), and lost it to Spassky in 1969. Thus he was the defending World Champion or a World Championship Candidate in ten consecutive three-year cycles. He won the Soviet Championship four times (1959, 1961, 1969, and 1975).
