Yuri Andropov
His earliest documented name was Grigory Vladimirovich Andropov-Fyodorov; he changed it to Yuri Andropov only several years later. While his original birth certificate disappeared, it was established that Andropov was in fact born in Moscow where his mother had been working in a women's gymnasium since 1913 throughout 1914 and until 1917.
Alexander Cherepkov
Alexander Vasilyevich Cherepkov was born in Leningrad. He served in the Soviet Red Army during World War II, and was decorated four times. He was a Soviet Master from the late 1940s, but took some time to climb through the deep hierarchy of talent. His first important result was clear 1st at Yaroslavl 1948 with 12.5/17 (this was likely a Soviet Championship quarter-final). His first attempt to qualify for the Soviet final saw him score 6.5/16 in the semi-final at Moscow, 1949. In the Leningrad Championship of 1950 he scored 7/13 for 6th place, but he fell short again at the Soviet semi-final level (Tartu 1950) with 5.5/15.
