"That radioactive elements created by us are found in nature is an astounding event in the history of the earth. And of the Human race. To fail to consider its importance and its consequences would be a folly for which humanity would have to pay a terrible price. When public opinion has been created in the countries concerned and among all the nations, an opinion informed of the dangers involved in going on with the tests and led by the reason which this information imposes, then the statesmen may reach an agreement to stop the experiments."

Albert Schweitzer. "Excerpts from Message by Schweitzer," The New York Times. April 24, 1957.

"A humanitarian is a man who believes that no human being should be sacrificed to a project –- especially to the project of perfecting nuclear weapons to kill hundreds of millions of people."

Albert Schweitzer. "A Nobel scientist speaks: Every test kills..." Liberation (New York) 2, no. 11. February 1958.

"I am astonished that in the United States a scientist gets into such trouble because of his scientific beliefs; that your activity in 1957 and 1958 in relation to the petition to the United Nations asking for a bomb-test agreement causes you now to be called before the authorities and ordered to give the names of the scientists who have the same opinions that you have and who have helped you to gather signatures to the petition. I think that I must be dreaming!"

Albert Schweitzer. Letter to Linus Pauling. July 23, 1960.

"This was good news, to many who are strangers to you, but even more to those who are not. It is good to think of you in the company of George Marshall and Albert Schweitzer."

Robert Oppenheimer. Letter to Linus Pauling. October 11, 1963.
