The statement, which soon became known as the Russell-Einstein Manifesto, was released by Russell to great acclaim (from those who supported his anti-nuclear stance) and disapproval (from those who didn’t) at a widely-reported press conference at London’s Caxton Hall on July 9, 1955. The event was chaired by Jospeh Rotblat, the Polish-born physicist who, during the Second World War, had worked on the Manhattan Project and knew first-hand the awful power of nuclear weapons. The full text of the Manifesto is available on the website of the Pugwash Conferences.
