Russian physicist and Nobel Prize winner Vitali Ginzburg has died in Moscow at the age of 93.

Ginzburg helped develop Russia's hydrogen bomb in the 1940s and 1950s together with Andrei Sacharov, who later became an anti-Communist dissident. The two men stayed friends even after Sacharov was exiled in 1980.

In 2003 he received the Nobel Prize together with another Russian Alexei Abrikosov and an American Anthony Leggett for their theory on super conductors and super fluids.

Vatali Ginzburg was an atheist with a Jewish background. He criticised the increased influence of the Orthodox church after the fall of communism and the break up of the Soviet Union.
