UNITED KINGDOM - OCTOBER 25: The British philosopher and mathematician Lord Bertrand RUSSEL. This scientist went deeply through the principles of mathematic reasonment and received the Nobel Litterature Prize in 1950. He was also a fervent activist of the non-spreading of the nuclear weapon. It was for this reason that he adressed the Sovietic leader Nikita KHRUSHCHEV to ask him to calm down the tensions that rose with the question of Cuba.
