Obituary: Sir Joseph Rotblat

Full Guardian Obituary:

"Sir Joseph Rotblat, who has died aged 96, was a nuclear physicist and a tireless worker for peace. When he and his creation, the Pugwash Conferences on Science and World Affairs were jointly awarded the 1995 Nobel peace prize, some newspapers identified him only as a 'little known' physicist. But scientists in many disciplines, and officialdom in many countries, knew him well."

I suppose the Pugwash Conferences are a prototypical example of the use of communication in the scientific community to maintain links between nations in the face of political disputes.
