Sir Joseph RotblatBorn 4 Nov 1908; died 31 Aug 2005 at age 96. Polish-British physicist who is a leading critic of nuclear weaponry. Rotblat and the Pugwash Conferences, "for their efforts to diminish the part played by nuclear arms in international politics and in the longer run to eliminate such arms," received the Nobel Peace Prize in 1995. Forty years earlier, he and other scientists, with philosopher Bertrand Russell and Albert Einstein, published a manifesto calling on researchers to take responsibility for their work, particularly those working on the atomic bomb. This led to the Pugwash Conferences on Science and World Affairs, first convened in 1957 in Pugwash, Nova Scotia, Canada. He was secretary-general (1957-73), and president (from 1988) of this London-based worldwide organization. |
