Biography

Legasov was born on September 1, 1936, in Tula, Russian SFSR, into a family of civil workers.[3][4][5] He attended secondary school in Kursk.[3] In 1949–1954, he attended School No. 56 in Moscow and graduated with a gold medal.[3] The school now bears his name, and his bronze bust stands at the entrance. He married Margarita Mikhailovna and had a daughter, Inga Legasova.[6][7][8]

In 1961, he graduated from the Faculty of Physicochemical Engineering at the Mendeleev Moscow Institute of Chemistry and Technology.[9]

He worked as secretary of the Komsomol Committee of the Moscow Institute of Chemical Technology.

In 1962, he joined the graduate school in the Department of Molecular Physics of the Kurchatov Institute of Atomic Energy,[10]:261 first as a junior then senior researcher, and finally as head of the laboratory. In 1967, he defended his thesis at the Kurchatov Institute, under the supervisor Isaac Kikoin, on the synthesis of compounds of noble gases and the study of their properties.[10]:261 He received the degree of candidate in 1967 and his doctorate in chemistry in 1972.[11]

In 1976, he was elected a corresponding member of the Academy of Sciences of the USSR.

From 1978 to 1983, he was a professor at the Moscow Institute of Physics and Technology.[12]

In 1981, he became a full member of the Academy of Sciences of the USSR, in the Department of Physical Chemistry and Technology of Inorganic Materials.

From 1983 until his death, he worked as chair of the department of Radiochemistry and Chemical Technology at the Faculty of Chemistry at Moscow State University.[12] In 1983,[12] he became the first Deputy Director for scientific work of the Kurchatov Institute of Atomic Energy.[13]

Legasov studied methods for the synthesis and the properties of new compounds with elements in high oxidation states; nuclear and plasma technology; energy-saving technology, and hydrogen energy. Under his leadership, a scientific school was created in the newest section of inorganic chemistry – chemistry of noble gases.

Even before the Chernobyl disaster, Legasov was known to stress the need for new security and safety methods to prevent large catastrophes.[14][15]

Main article: Chernobyl disaster

By the time of the Chernobyl disaster on 26 April 1986, Legasov was the first deputy director of the Kurchatov Institute of Atomic Energy.[16] He became a key member of the government commission formed to investigate the causes of the disaster and to plan the mitigation of its consequences. He took many important actions to avoid repeat accidents and informed the government of the situation in the disaster area. He did not hesitate to speak to his fellow scientists and to the press about the safety risks of the destroyed plant and insisted on the immediate evacuation of the entire population of the city of Pripyat nearby. In August 1986, he presented the report of the Soviet delegation at the special meeting of International Atomic Energy Agency (IAEA) in Vienna. His report displayed a depth of analysis and honesty in discussing the extent and consequences of the tragedy.[17] Legasov recorded five audio tapes[18] where he expressed his point of view on events that happened in Chernobyl. The fifth and last tape was recorded with Ales Adamovich as an interview for an article.

Death
The grave of Professor Valery Legasov at Novodevichy Cemetery in Moscow.

On 27 April 1988,[19] one day after the second anniversary of the Chernobyl Nuclear Power Plant accident and one day before he was due to announce his results of the investigation into the causes of the disaster, Legasov hanged himself (some sources say in his apartment[2][20] or the stairwell of his apartment;[21] others in his office[22]). A personal pistol remained in a drawer, but the professor chose to hang himself. He was buried at the Novodevichy cemetery in Moscow.[23][24]

This was not Legasov's first suicide attempt.[25] David R. Marples has suggested that the adversity of the Chernobyl disaster on Legasov's psychological state was the factor that led to his decision to die by suicide.[9] Before his suicide, Legasov wrote documents revealing previously undisclosed facts about the catastrophe.[22] According to an analysis of the recording for the BBC TV movie Chernobyl Nuclear Disaster,[26] Legasov claims political pressure censored the mention of Soviet nuclear secrecy in his report to the IAEA, a secrecy which forbade even plant operators having knowledge of previous accidents and known problems with reactor design.[27] The Bulletin of the Atomic Scientists also stated that Legasov had become bitterly disillusioned with the failure of the authorities to confront the design flaws.[28]

Aftermath

Legasov's suicide caused shockwaves in the Soviet nuclear industry. In particular, the problem with the design of the control rods in Chernobyl-type RBMK reactors was rapidly admitted and addressed.[26][29]

On 20 September 1996, then-Russian president Boris Yeltsin posthumously conferred on Legasov the honorary title of Hero of the Russian Federation, the country's highest honorary title, for the "courage and heroism" shown in his investigation of the disaster.[30]

In media

Legasov is portrayed by Ade Edmondson in the BBC docudrama Surviving Disaster (2006), by Adam Curtis in his documentary series Pandora's Box (1992), and by Jared Harris in the Sky/HBO miniseries Chernobyl (2019).
