A movement of scientists

Founded in 1957, Pugwash values and principles are rooted in the Russell–Einstein Manifesto and its enduring warning that humanity must choose between ending war and ending civilisation.

In 1995, the Pugwash Conferences and one of its co-founders, the late physicist Sir Joseph Rotblat, shared the Nobel Peace Prize in recognition of their decades-long work to reduce the threat of nuclear war and seek the abolition of nuclear weapons.
