where his brother Ivan, a blacksmith, had been exiled the year before for failing to deliver his grain quota.[9] Nikolai remained unemployed for a period of time and then worked again in construction. His mother, Klavdiya Vasilyevna Yeltsina, worked as a seamstress.
Boris Yeltsin studied at Pushkin High School in Berezniki in Perm Krai. He was fond of sports (in particular skiing, gymnastics, volleyball, track and field, boxing and wrestling) despite losing the thumb and index finger of his left hand when he and some friends furtively entered a Red Army supply depot, stole several grenades, and tried to disassemble them.[10]
In 1949 Yeltsin was admitted to the Ural Polytechnic Institute in Sverdlovsk, majoring in construction, and he graduated in 1955. The subject of his degree paper was "Construction of a Mine Shaft".[11]
From 1955 to 1957 he worked as a foreman with the building trust Uraltyazhtrubstroy. From 1957 to 1963 he worked in Sverdlovsk, and was promoted from construction site superintendent to chief of the Construction Directorate with the Yuzhgorstroy Trust. In 1963 he became chief engineer, and in 1965 head of the Sverdlovsk House-Building Combine, responsible for sewerage and technical plumbing. He joined the ranks of the CPSU nomenklatura in 1968 when he was appointed head of construction with the Sverdlovsk Regional Party Committee. In 1975 he became secretary of the regional committee in charge of the region's industrial development. In 1976 the Politburo of the CPSU promoted him to the post of the first secretary of the CPSU Committee of Sverdlovsk Oblast (effectively he became the head of one of the most important industrial regions in the USSR), he remained in this position until 1985.
