Andrei Sakharov (1921-1989) - physicist, academician of the USSR Academy of Sciences, public figure and human rights activist. In 1942, Sakharov graduated from the Physics Department of Moscow State University, receiving a diploma with honors in the specialty "defense metallurgy". In 1945 he entered the graduate school of the Physics Institute of the USSR Academy of Sciences named after V.I. Lebedev (FIAN). Three years later, a special research group was formed at the Physics Institute - it checked the calculations for the creation of a hydrogen bomb. Andrei Sakharov was also included in this group. The future project was based on information received from foreign scientists; Sakharov, on the other hand, proposed a fundamentally different project for a thermonuclear charge. The first test of a hydrogen bomb took place on August 12, 1953. In October of the same year, Sakharov was unanimously elected Academician of the Academy of Sciences. In 1955, an "improved" hydrogen bomb was tested - the same group was working on it. Sakharov by this time began to think about the humanitarian consequences of nuclear tests. In 1958, the academician published an article on the radioactive consequences of the explosions of a thermonuclear bomb, calling for an end to nuclear tests. The USSR, Great Britain and the USA signed the Treaty Banning Nuclear Weapon Tests in Three Environments in 1963. Since the 1960s, Andrei Sakharov has been actively involved in social activities. Opposed the new law, which allows "more massive persecution for beliefs and information activities." As part of the Committee on Lake Baikal, he fought for the prohibition of industrial activities on the shore of the lake. In 1968 he wrote an article "Reflections on Progress, Peaceful Coexistence and Intellectual Freedom." Since 1970, he was a member of the Human Rights Committee. In 1975, Andrei Sakharov was awarded the Nobel Peace Prize.
