Sir Joseph Rotblat

Sir Joseph Rotblat, who died in August 2005, was one of the scientists recruited to build the atomic bombs which brought World War II to an end. Turning his back on the nuclear program, he subsequently became a tireless campaigner for the abolition of nuclear weapons. Co-founder in 1957 of the Pugwash Conferences on Science and World Affairs, he received both the Albert Einstein Peace Prize in 1992 and the Nobel Peace Prize in 1995.
