British scientist Joseph Rotblat, a Nobel Peace Prize winner who campaigned strongly against nuclear weapons, has died in London at the age of 96.
Associates of Mr. Rotblat say he died in his sleep on Wednesday night.
Mr. Rotblat was one of 11 scientists, including Albert Einstein, who signed a manifesto in 1955 calling upon world leaders to renounce nuclear weapons and in their words "remember their humanity."
To promote nuclear disarmament, he helped found the Pugwash Conferences on Science and World Affairs which worked to reduce the chances of armed conflict.
He and the group were awarded the Nobel Peace Prize in 1995.
