Khrushchev's chief investigator who traced Stalin's crimes to the end

"Nikita Sergeyevich, you know that I am not an enemy of the people." — a single line sent from exile to Khrushchev, 1954

An Old Bolshevik who joined the party at 15 in 1916. As chief investigator of the Shvernik Commission under Khrushchev, she proved in 64 volumes that the Kirov murder, Moscow show trials, and Katyn massacre were Stalin's fabrications. She survived eight years in Kolyma and was rehabilitated.

Long-serving Gosplan chairman of the stagnation era

Some colleagues turned out to be scoundrels — they tried to brand me an enemy of the people. To dodge that filthy investigation, I joined the Red Army.

A Baku-born oil engineer who led the Soviet oil industry in his thirties, devising the 'Baibakov method' of high-pressure cement injection to revive waterlogged wells. During the war he carried out the dramatic Caucasus oilfield denial mission; afterward he drove the Romashkino field development that helped make the USSR a petroleum superpower. As Gosplan chairman for twenty years from 1965, he personified post-Kosygin-reform central planning and remained a mainstay of the Brezhnev-era administrative system until Gorbachev replaced him.

The Azeri engineer who built the Soviet gas industry into the world's largest

Landing on the bare tundra at the future Urengoy site in 1973, Orudzhev declared: "I am not Peter the Great, but I will borrow his words: here a city shall be built." From that moment, Novy Urengoy — Russia's 'gas capital' — was born.

An Azeri engineer from a Baku working-class family who built the Soviet gas industry into the world's largest. As Minister of the Gas Industry from 1972, he developed the West Siberian supergiant fields of Urengoy and Medvezhye and created the Unified Gas Supply System (ЕСГ), which remains the backbone of Russian gas power today.

The long-hidden manager of crewed spaceflight

On April 12, 1961, Yuri Gagarin slept soundly before humanity's first spaceflight. Kerimov, monitoring the cosmonaut's sleep via bed sensors, spent a far more anxious night than the man about to ride the rocket.

His career began in World War II inspecting Katyusha rockets and gathering intelligence on the German V-2. He served on the State Commissions for Sputnik 1 and the Vostok programme, then chaired the State Commission for crewed flights from 1966 to 1991, twenty-five years in which he gave the final launch approval for every Soviet crewed mission. He was the administrative gatekeeper of Soviet crewed spaceflight's golden age, from Salyut and Soyuz-Apollo to Mir, yet his identity was kept strictly secret until perestroika.

The KGB general who rose from Baku to the Kremlin and founded independent Azerbaijan

F. D. Bobkov, first deputy KGB chairman, asked him after three years: "What have you managed to achieve?" Aliyev replied: "I can guarantee only one thing — in the Central Committee of the Communist Party of Azerbaijan, no one takes bribes."

An Azerbaijani who served 28 years in Soviet state security, Aliyev rose from KGB chairman to First Secretary of the Azerbaijan Communist Party in 1969. Under Brezhnev, he drove rapid economic growth in the republic, expanding grape, oil, and cotton production, and became one of the few non-Slavs to reach the post of First Deputy Chairman of the USSR Council of Ministers and full Politburo member in 1982. Returning to Azerbaijan as it descended into civil war after the Soviet collapse, he became president in 1993, stabilized the country, and signed the 'Contract of the Century' for Caspian oil development, securing his legacy as the founder of independent Azerbaijan.
