ANDREY SAKHAROV

Andrey Sakharov, the outstanding nuclear physicist, was born in Moscow, Russia on May 14. He won a doctorate at the age of 26 and was admitted as a full member of the Soviet Academy of Sciences at age 32.

Having invented the deadly weapon, nevertheless, Andrey Sakharov was an outspoken advocate of human rights, civil liberties and reforms in the country. As a prominent Soviet scientist, he was accorded luxuries and honors. But in 1961 he went on record against the plan to test a 100-megaton hydrogen bomb in the atmosphere, fearing the effects of widespread radioactive fallout. He was awarded the Nobel Prize for Peace, but in 1975 the Soviet scientist had to overcome many obstacles in his way for world recognition and awards.

3. In 1968 Sakharov published in the West his essay “Progress, Coexistence and Intellectual Freedom”, in which he called for nuclear arms reductions and criticized the increasing repression of Soviet dissidents.

In December 1979, with his denunciation of the Soviet invasion of Afghanistan and his call for a world boycott of the Moscow Olympic Games, he was silenced. He was not able to publish his works in his country.

A year later, the Soviet government stripped him of his honors and exiled him to the closed city of Gorky (now Nizhny Novgorod). M. S. Gorbachev in 1986 released Sakharov and let him return to Moscow.
