Earlier this year, The Bank of Russia issued a commemorative coin dedicated to Andrei Sakharov. Sakharov was a Soviet nuclear physicist, dissident, Nobel laureate, and activist for disarmament, peace and human rights. 2021 marks the 100th anniversary of his birth. The coin’s portrait is based on Karsh’s photograph of Sakharov, made in February 1989, just 10 months before Sakharov’s death.
