 In 1954, Russell delivered his famous “Man’s Peril” broadcast on the BBC, condemning the Bikini H-bomb tests. A year later, together with Albert Einstein, he released the Russell-Einstein Manifesto calling for the curtailment of nuclear weapons. In 1957, he became a prime organizer of the first Pugwash Conference, which brought together a large number of scientists concerned about the nuclear issue. He became founding president of the Campaign for Nuclear Disarmament in 1958 and Honorary President of the Committee of 100 in 1960.
