childhood
Born on 17 June 1929 in Tbilisi, Georgia, into an Armenian family; his father was a caretaker (dvornik).
Learned chess at age 8; his father encouraged him to study, not knowing chess would become his career.
He saved money to buy Aron Nimzowitsch's My System in Practice, which he learned almost by heart.
He kept Nimzowitsch's book under his pillow like a child keeps a storybook.

Was an excellent student who loved studying; he attended Armenian school in Tbilisi.
His formal higher education was limited by the upheavals of World War II and family responsibilities, but he was deeply self-educated in chess theory.

Ninth World Chess Champion, holding the title from 1963 to 1969.
Defeated Mikhail Botvinnik in 1963 and successfully defended against Boris Spassky in 1966 before losing to Spassky in 1969.
Known as "Iron Tigran" for his almost impenetrable defensive style; he was extremely difficult to beat.
