Its focus on private meetings that address the interrelated issues of nuclear disarmament, non-military resolution of conflict, and the social responsibility of scientists derives from the famous Russell-Einstein Manifesto of 1955—the last public statement from Albert Einstein.
The organization’s name comes from Pugwash, Nova Scotia, where the landmark meeting of scientists from East and West took place in 1957 during some of the darkest days of the Cold War.
The organization, which involves both scientists and non-scientists, prioritizes preservation of the basic principles of the NPT (disarmament, non-proliferation and access to nuclear energy for all the Member States).
Paolo Cotta-Ramusino is an internationally recognized expert on these issues, and regularly writes and gives presentations on current topics in arms control, disarmament and conflict resolution at leading academic, research and governmental institutions, including recent talks, for example, at The World Summit of Nobel Peace Laureates, The International Institute of Strategic Studies, The Italian Parliament, Rome, The Royal Society, London, Council on Foreign Relations, Washington, DC, UK parliament, among others.
