Founder of Soviet naval strategic rocketry, the man the CIA called 'the Ural Dragon'

In 1955, Korolev offered the 30-year-old Makeyev a post as deputy chief designer of the Urals branch. Makeyev replied: "I'll go to the Urals only as a chief designer. I won't go as a deputy." Korolev was stunned by the audacity — but appointed him chief designer of SKB-385.

A draftsman at an aviation plant who caught Korolev's eye and became chief designer of SKB-385 at 31. Over three decades leading a single design bureau, he developed three generations of submarine-launched ballistic missiles, achieving underwater launch, factory fueling, intercontinental range, and MIRV capability in succession, completing the strategic balance of Cold War naval nuclear deterrence. Western intelligence, ignorant of his identity, called him 'the Ural Dragon'; his R-17 became globally known under its NATO code name: Scud.

The chief designer who built a Soviet satellite empire in the Siberian taiga

Baikonur, 1987. Gorbachev surveyed the satellites and asked: "You do all this in Siberia?" Reshetnev answered: "In Siberia. But we work with Moscow, Leningrad, and 200 other cities."

A rocket engineer who began as Korolev's deputy, in 1961 he founded the independent design bureau OKB-10 in the closed Siberian city of Krasnoyarsk-26. He delivered the Molniya, Strela, Raduga, and Ekran communications and broadcasting satellite families, expanded into geodesy, rescue, and navigation, and in 1982 launched the GLONASS global satellite navigation system. The enterprise he built, NPO PM (Applied Mechanics Science-Production Association), produced more than 30 space systems and over 1,000 satellites, accounting for two-thirds of all Soviet satellites; it survives today as ISS Reshetnev and remains the backbone of Russian satellite manufacturing. Hero of Socialist Labor, Lenin Prize laureate, and full member of the USSR Academy of Sciences.

Science and technology Soviet Union state institutions 1925–1970 ○ Peritonitis

The fighter pilot who commanded the first spacewalk

The automatic guidance was dead. Belyayev lay across the seats, sighting through the Vzor navigator, and oriented the capsule by hand. Leonov held him in place. It was the first fully manual reentry in the history of spaceflight.

A Pacific Fleet fighter pilot, Belyayev was the oldest candidate (thirty-four) and highest-ranking, a major, when the first cosmonaut group formed in 1960, making him its inaugural commander. On March 18, 1965, as commander of Voskhod 2, he oversaw Alexei Leonov's historic first spacewalk, then performed the first fully manual reentry in spaceflight history when the automatic guidance failed, lying across the seats to use the Vzor navigator. The capsule overshot by 2,000 kilometres into the Perm taiga, where he and Leonov spent two subzero nights before rescue. Made a Hero of the Soviet Union, he later directed Soyuz training but died of peritonitis after ulcer surgery in 1970 at forty-four.

Last President of the USSR Academy of Sciences and pioneer of computational mathematics in Siberia

“Science is a single living organism, not a conglomerate of autonomous mechanisms. Unfortunately, neither the politicians nor the scientific community have the concept of saving domestic science.” — 17 December 1991

An applied mathematician who built the centre of computational mathematics in Siberia and rose to the pinnacle of Soviet science administration. He pioneered nuclear-reactor calculations, atmospheric and ocean modelling, and mathematical immunology, laying the foundations with splitting methods and adjoint-equation theory. In 1964 he founded the Computing Centre in Novosibirsk, the USSR's first large-scale numerical-modelling centre. As GKNT Chairman and Deputy Premier from 1980, then Academy President from 1986, he steered Soviet science through perestroika. He became the last President of the USSR Academy of Sciences.

Science and technology Soviet Union state institutions 1927–1967 ✕ Killed in crash

Voskhod 1 commander and the first human to perish in a spaceflight

"I cannot orient the spacecraft to the sun" — amid cascading failures aboard Soyuz 1, Komarov continued manual troubleshooting and reporting to ground control until the final descent.

A Soviet Air Force test pilot and aerospace engineer, he commanded Voskhod 1 in 1964, the world's first multi-crew spaceflight. One of only two cosmonauts in the first group to hold an Air Force Academy engineering degree, he contributed significantly to Vostok and Voskhod spacecraft design and to cosmonaut training evaluation. In 1967 he flew Soyuz 1 solo on its first crewed test flight; after re-entry, a parachute failure caused the capsule to crash, making him the first human to die in a spaceflight. His death forced a fundamental review of design verification and safety procedures across the Soviet crewed space program.

From nuclear-weapon designer to critic of the arms race

Of the nuclear arms race, he wrote: “I cannot see a use even for one bomb.”

Lev Feoktistov was a Soviet theoretical physicist who helped develop nuclear and thermonuclear weapons before becoming an advocate of disarmament and reactor safety. At Arzamas-16, he worked on thermonuclear designs growing out of the Sloika and left a firsthand account of the breakthrough known as the “Third Idea,” the emergence of a workable two-stage design. He recognized the technical achievements of the weapons program while questioning the logic of nuclear testing and the arms race, and later turned to laser fusion and inherently safe reactors.

Philosopher who bridged Soviet planning science and Western systems analysis

His forename "Dzhermen" was composed by his father from the first syllables of the surnames of Felix Dzerzhinsky and Vyacheslav Menzhinsky — the two OGPU chairmen under whom his father served.

Soviet philosopher, sociologist, and management theorist. Son-in-law of Alexei Kosygin, he served as Deputy Chairman of the State Committee for Science and Technology (GKNT) from 1965 to 1985, coordinating Soviet science and technology policy. A member of the Club of Rome and co-founder of the International Institute for Applied Systems Analysis (IIASA) in Austria, he was a rare bridge between Soviet planning science and Western systems analysis during the Cold War. In 1976 he founded and directed the All-Union Research Institute for Systems Analysis (VNIISI), known for its relatively free-thinking atmosphere and its incubation of market-oriented reform ideas that fed into perestroika-era economic debates.

Physicist from Sakharov's group who became the lead declassifier and historian of the Soviet H-bomb project

Against the mystery of the 'Third Idea' that Sakharov himself left ambiguous, Goncharov concluded that its seed lay in Klaus Fuchs's 1948 report.

A Soviet nuclear physicist who began his career in Sakharov's theoretical department, Goncharov participated directly in the development of the RDS-6s (1953), RDS-37 (1955), and Tsar Bomba (1961), and proposed a new design direction for megaton-class thermonuclear charges. In the late Cold War, as the lead declassifier of Soviet nuclear archives under Yeltsin, he compiled the multivolume 'USSR Atomic Project: Documents and Materials' and published key papers analyzing Klaus Fuchs's 1948 report and the origins of the 'Third Idea,' placing himself at the center of the historiographical debate. His archival work provided the empirical foundation for arguments over whether the 1955 radiation implosion design was an indigenous achievement or aided by espionage.

Science and technology Soviet Union state institutions 1929–2004 ○ Heart attack

Soviet cosmonaut who flew humanity's first multi-day spaceflight aboard Vostok 3

The moment Vostok 3 reached orbit, Nikolayev unstrapped himself and floated free inside the cabin: Gagarin had not done it, nor had Titov. It was the first time a human being had ever slipped free of gravity's hold in space.

Born to a Chuvash peasant family, Nikolayev became the third Soviet cosmonaut in space. In August 1962, aboard Vostok 3, he orbited Earth 64 times over four days, humanity's first multi-day spaceflight, and his joint flight with Pavel Popovich's Vostok 4 established the dual-launch precedent later used for the women's space mission. His flight data proved that missions exceeding three days were feasible. In 1970, his 18-day Soyuz 9 mission with Vitaly Sevastyanov revealed the severe physiological toll of prolonged weightlessness, the 'Nikolayev effect', while his 1963 marriage to Valentina Tereshkova, presided over by Khrushchev, became a signature Cold War propaganda spectacle.

The father of Soviet cardiology who ran Kremlin medicine for 20 years

“Nuclear war, unless it is prevented, would lead to the extinction of life on Earth and possibly in the Universe. Can we take such a risk?” — Nobel lecture, Oslo, 1985

Yevgeny Chazov was a Soviet cardiologist who pioneered thrombolytic therapy for myocardial infarction and oversaw Kremlin medicine for twenty years, treating successive leaders from Brezhnev to Chernenko. In 1980 he co-founded International Physicians for the Prevention of Nuclear War with American cardiologist Bernard Lown, receiving the 1985 Nobel Peace Prize, a rare Cold War collaboration across the blocs.

Cosmonaut No. 4, Vostok 4 pilot of the first simultaneous crewed spaceflight

At Korolev's request during the flight, he sang the Ukrainian folk song 'I gaze at the sky and ponder a thought,' the first human song ever performed in space.

The fourth Soviet cosmonaut and the first Ukrainian in space, he served as capcom for Gagarin's Vostok 1 flight. In August 1962 he piloted Vostok 4 alongside Andriyan Nikolayev's Vostok 3 in the world's first simultaneous crewed orbital flight; the two craft came within 6.5 km of each other, and Popovich performed the first musical piece in space, a Ukrainian folk song. In 1974 he commanded Soyuz 14, docking with the first military crewed space station Almaz (Salyut 3), and became twice a Hero of the Soviet Union.

Science and technology Estonia state institutions 1930–2015 ○ Died, aged 84

The Estonian scientist who blocked phosphorite mining from inside the system

He stood out in TV debates by carrying a portfolio of documents and smoothly pulling out the relevant one to prove his point whenever opponents challenged him.

Estonian chemical physicist and politician. After studying oil-shale technology at Tallinn Polytechnic, he built the Soviet bloc's first NMR spectrometer and became a pioneer of high-resolution solid-state NMR spectroscopy. As a member of the Estonian Academy of Sciences, he led scientists in exposing the environmental and demographic dangers of planned phosphorite mines in 1987, providing the intellectual foundation for the 'Phosphorite War,' a catalyst for mass resistance and the independence movement. As a USSR People's Deputy, he unearthed and publicised the secret protocols of the Nazi-Soviet Pact, demolishing the legal basis for the Baltic annexation; after independence he served twice as a government minister.

The last chairman of Soviet state science policy and a uranium geologist

Receiving the Global Energy Prize in 2009 he observed: "The Earth has always alternated between cold and warm periods, and humans have lived through only a very short moment on the geological time scale."

Soviet geologist and science administrator. His work on uranium deposits across Central Asia and Russia established the resource base for the Soviet nuclear fuel cycle, and in the final perestroika years he served simultaneously as chairman of the State Committee for Science and Technology (GKNT) and Deputy Chairman of the USSR Council of Ministers: the last person to direct Soviet science and technology policy. As Vice President of the Soviet and then Russian Academy of Sciences from 1988 to 2013, he led the Earth sciences section and became a leading authority on radioactive waste disposal and Arctic research. He authored over 700 scientific papers and 28 monographs.

Communist physicist whose semiconductor heterostructures opened the IT era

Demonstrating Russia's social stratification in the 2000s, he held up a wine glass and said: 'The contents of this glass belong — alas! — to just ten percent of the population. And the stem that holds the glass is the rest of the population.'

Zhores Alferov was a Soviet applied physicist who pioneered semiconductor heterostructure physics and built the first continuous-wave room-temperature semiconductor laser in 1968, laying the physical foundation for fiber-optic communication, CDs, and barcode readers. For this work he received the Nobel Prize in Physics in 2000. As director of the Ioffe Institute from 1987, chairman of the St. Petersburg Scientific Center from 1989, and vice-president of the USSR and Russian Academy of Sciences, he preserved Russia's basic science through the collapse of the Soviet Union. He served in the State Duma from 1995 on the Communist Party list, defending science funding and fiercely opposing the 2013 Academy reforms. Named after Jean Jaurès, he remained a communist all his life while leading one side of the Cold War's optoelectronics race.

Science and technology Soviet Union state institutions 1931–1995 ○ Radiation-related illness

The deputy chief engineer who supervised the Chernobyl safety test and later argued the reactor's design was the real cause

The reactor protection system designed to stop the fission in an emergency situation played the role of atomic bomb detonator.

Born into a poor family in Siberia, he ran away from home at 14, trained at the Norilsk technical school, and graduated with honors from the Moscow Engineering and Physics Institute. He spent fourteen years installing naval nuclear reactors at a shipyard in the Soviet Far East before moving to Chernobyl in 1973, where he became deputy chief engineer in charge of Units 3 and 4. On 26 April 1986 he supervised the safety test at Unit 4 that ended in disaster; he insisted design flaws caused the accident but was convicted in 1987 and sentenced to ten years, released early in 1990 on health grounds. From prison he wrote to expose the RBMK's structural defects and authored Chernobyl: How It Was; the 1992 IAEA advisory report partly vindicated his argument.

The most qualified female cosmonaut candidate, grounded by politics

She told Tereshkova, 'The Komsomol and the party have irreparably spoiled you,' Kamanin recorded in his diary.

A Moscow Aviation Institute graduate and the only pilot among the five women selected for the cosmonaut corps in 1962, she scored highest on her final exams, and medical director Yazdovsky ranked her first for flight. But Kamanin recorded her independent manner as 'arrogance,' her smoking and drinking as 'moral instability,' and Korolev told her a working-class woman was needed for the flight, so Tereshkova was chosen. She later trained for an all-female Voskhod mission with a spacewalk, but the program was cancelled, and she never flew.

Gagarin's second backup, the cosmonaut ranked third for the first flight who never reached orbit

On 18 February 1966, the note he left his wife before leaving home: "Zinok! You were always the best. You'd have to search to find a woman like you. Forgive me."

In January 1961 the State Commission ranked the first-flight candidates: Gagarin, Titov, Nelyubov. He was the second backup for Vostok 1 and later trained as backup for the Vostok 3/4 dual flight, but in March 1963 a clash with a military patrol at Chkalovskaya station (drunk, and refusing to apologize) cost him his place in the cosmonaut corps. Exiled to a fighter unit in the Far East, he fell into alcoholism and depression; on 18 February 1966 he stepped in front of a train, aged thirty-one. His existence was kept secret until glasnost, his image airbrushed from the 'Sochi Six' photograph and his name erased from official histories.

The first human smile to leave the Earth

Re-entry: the capsule engulfed in 3,000-degree plasma, ten Gs pressing on his body. Inside, Gagarin whistled — Shostakovich's "The Motherland Hears, The Motherland Knows." He later wrote in his autobiography: "I sang that song the whole way down to Earth."

A collective-farm carpenter’s son circled the planet in 108 minutes on April 12, 1961: “Poyekhali!”, let’s go. In the middle of the Cold War he became the one man both camps loved. Training for a return to space, he died in a MiG crash in 1968. He was thirty-four.

First to open the door to the cosmos, and the first to draw it from inside

"It was so quiet I could even hear my heart beat. I was surrounded by stars and was floating without much control." — the first human to walk in space, 18 March 1965.

A Siberian miner's son, Leonov became the first human to walk in space on 18 March 1965, floating outside Voskhod 2 for twelve minutes, and nearly dying when his suit ballooned so badly he had to bleed oxygen to squeeze back into the airlock. He was also the first artist in space, sketching an orbital sunrise with coloured pencils tethered together in weightlessness. A decade later, as commander of Soyuz 19, he led the Soviet half of the Apollo-Soyuz Test Project (the first US-Soviet docking in orbit) and forged a lifelong friendship with American commander Thomas Stafford. From 1976 to 1982 he served as deputy director of the Yuri Gagarin Cosmonaut Training Center and chief cosmonaut, overseeing the next generation. Twice Hero of the Soviet Union and a major general of aviation, he produced over 200 space-themed paintings across a life that fused exploration with art.

The cosmonaut who spent five days alone in orbit, setting a solo spaceflight record that still stands

On 18 June 1963, while Vostok 5 was still orbiting, the Party Central Committee reviewed his application and admitted him as a full member without a candidate period.

Soviet cosmonaut, the fifth to fly in space. Launched on 14 June 1963 aboard Vostok 5, he orbited Earth 81 times over nearly five days, setting a solo space endurance record that still stands. The original Vostok plan called for two women to fly simultaneously, but the mission was restructured as one woman and one man: Bykovsky launched two days before Valentina Tereshkova. He went on to command Soyuz 22 (1976) and Soyuz 31 (1978) with East Germany's first cosmonaut Sigmund Jähn, becoming the only Vostok/Voskhod-era cosmonaut to complete three spaceflights.

Khrushchev's son and Chelomei's guidance-system engineer

During the Apollo 11 Moon landing in 1969, Khrushchev tried to watch the historic moment through a telescope from Ukraine — with a KGB officer at his side.

Soviet rocket engineer and computer scientist. The son of Nikita Khrushchev, he developed guidance systems for cruise missiles and the Proton space booster at Vladimir Chelomei's OKB-52 design bureau, contributing to submarine-launched missiles, military spacecraft, Moon vehicles, and the Proton booster. At age 28 he was named a Hero of Socialist Labor and awarded the Order of Lenin in 1963. He later served as first deputy director of the Control Computer Institute (INEUM), and after moving to the United States in 1991 taught Cold War history and the Soviet space program at Brown University's Watson Institute while publishing several books on his father's era.

The first director of Chernobyl who built the plant and was held responsible for its catastrophe

In the station courtyard I saw pieces of graphite under my feet, but I still could not imagine that the reactor had been destroyed.

Born in Tashkent as the eldest son of Russian workers, he studied energy engineering and built his career at thermal power plants. In 1970 he was appointed construction manager and first director of the Chernobyl Nuclear Power Plant, which he led for sixteen years; plagued by construction delays and defective materials, he submitted his resignation, but a Party supervisor tore it up. Dismissed immediately after the 1986 disaster, he was sentenced to ten years in 1988; after his release he continued working on Chernobyl liquidation until his death in Kyiv in 2021.

Soviet physicist who linked fusion science, Chernobyl, and nuclear disarmament

Less than a month after absorbing radiation at Chernobyl, Velikhov chaired an international meeting on nuclear test-ban verification — turning disaster into a disarmament opening.

Soviet physicist who pioneered plasma physics for controlled fusion and MHD power. His 1959 thesis discovered magnetorotational instability, now foundational to astrophysics; in 1962 he identified electrothermal instability. He led the Soviet controlled-fusion program from 1973 and was Vice-President of the USSR Academy of Sciences (1978–1991), bridging the Kurchatov Institute and the Academy. During Chernobyl (1986) he served as Gorbachev's science advisor for reactor containment, then led science diplomacy for nuclear disarmament. After the Soviet collapse he sustained the Kurchatov Institute and became founding chairman of ITER, building the framework for joint US-Soviet-European-Japanese fusion research.

The Kurchatov chemist who led science at Chernobyl, then left the full truth on tapes before hanging himself

"I did not lie in Vienna… but I did not tell the full truth."

Valery Legasov was a Soviet inorganic chemist and first deputy director of the Kurchatov Institute of Atomic Energy, who arrived at the Chernobyl disaster site on the evening of 26 April 1986 as the scientific leader of the government commission. He proposed dropping boron and sand into the burning reactor, spent a total of 60 days on site, and later presented a five-hour report to the IAEA in Vienna that drew international attention but stopped short of revealing the RBMK reactor's full design flaws. On 27 April 1988, the day after the disaster's second anniversary, he hanged himself in his Moscow apartment; the audio tapes he recorded beforehand exposed the cover-ups and systemic failures of the Soviet nuclear establishment and became a primary source for historians.
