Russell–Einstein Manifesto

• 1. Introduction

  ›

  The Russell-Einstein Manifesto was issued in London on the 9th of July 1955, at a moment when the Cold War had already reshaped what the phrase "human survival" could mean. Bertrand Russell stood before a packed room at Caxton Hall and read a document signed by eleven of the most distinguished scientific minds in the world, including Albert Einstein, who had put his name to it just days before his death on the 18th of April 1955. At least 100,000 civilians had been killed outright by the bombings of Hiroshima and Nagasaki a decade earlier. Those facts were not ancient history. They were the recent past. The document Russell read that day did not propose a new weapon or a new alliance. It proposed something stranger and harder: that the governments of the world simply allow their citizens to survive. What drove eleven of the world's leading intellectuals to issue that appeal? And what happened after the press cameras left Caxton Hall?

• 2. The Shadow of the Bomb

  On the 16th of July 1945, the first atomic weapon was detonated in the desert north of Alamogordo, New Mexico. Less than a month later, Bertrand Russell published "The Bomb and Civilisation" in the Glasgow Forward on the 18th of August 1945. He had begun writing it the day Nagasaki was bombed. The piece already carried the argument that would anchor the manifesto: the human race faced a stark choice between collective perishing and the acquisition of what Russell called "some slight degree of common sense." Joseph Rotblat, the only scientist who had left the Manhattan Project on moral grounds, watched the bombings and said he "became worried about the whole future of mankind." Rotblat and Russell shared that alarm. Over the years that followed, they worked alongside Albert Einstein and others to translate private worry into a public document that governments could not easily ignore.

• 3. The Press Conference

  ›

  Rotblat chaired the press conference at Caxton Hall on the 9th of July 1955, and he later described an organising miscalculation. The team had expected a modest turnout and booked a small room. Interest kept rising, and they moved twice before taking the largest room available. Even that filled to capacity with journalists, radio correspondents, and television crews arriving from across the world. Russell opened by saying he was bringing "the warning pronounced by the signatories to the notice of all the powerful Governments of the world in the earnest hope that they may agree to allow their citizens to survive." Some members of the press were openly hostile at first. Rotblat noted that as Russell answered the barrage of questions, the reporters gradually came around, with many outlets giving the manifesto front-page coverage.

• 4. What the Manifesto Said

  ›

  The manifesto called for a conference of scientists to assess the dangers that weapons of mass destruction posed to the survival of humanity. Crucially, the document insisted the meeting be politically neutral. It treated nuclear danger not as a problem for governments alone but as a question for all people. One phrase from the text has been cited repeatedly in the decades since, including by Rotblat when he accepted the Nobel Peace Prize in 1995: "Remember your humanity, and forget the rest." The signatories numbered eleven in total. With one exception, Leopold Infeld, every signer was a Nobel Laureate, though Rotblat himself had not yet received that honour at the time he signed.

• 5. From Manifesto to Pugwash

  ›

  The manifesto called for an international conference, and the first plan was to hold it in India, organised by Jawaharlal Nehru. The Suez Crisis interrupted those preparations. Aristotle Onassis then offered to finance a meeting in Monaco, but that offer was declined. Cyrus Eaton, a Canadian industrialist who had known Russell since 1938, stepped in with a different proposal. Eaton offered to host and finance the conference in Pugwash, Nova Scotia, the town where he was born. The first Pugwash Conference on Science and World Affairs convened there in July 1957. The Russell-Einstein Manifesto became the founding charter of that ongoing series, a document written in the shadow of Hiroshima and Nagasaki that would shape the conversation about nuclear weapons for generations to come.
