“We knew the world would not be the same. A few people laughed; a few people cried. Most people were silent. I remembered the line from the Hindu scripture, the Bhagavad Gita; Vishnu is trying to persuade the prince that he should do his duty, and to impress him, takes on his multiarmed form and says, "Now I am become Death, the destroyer of worlds." I suppose we all thought that, one way or another.”

— J. Robert Oppenheimer, 1965 NBC interview

“There is no indication in the entire record that Dr. Oppenheimer has ever divulged any secret information. The past 15 years of his life have been investigated and reinvestigated. For much of the last 11 years he has been under actual surveillance, his movements watched, his conversations noted, his mail and telephone calls checked. This professional review of his actions has been supplemented by enthusiastic amateur help from powerful personal enemies.”

— Henry DeWolf Smyth, dissenting opinion, AEC security hearing, 1954

“I think there are issues which are quite simple and quite deep, and which involve us as a group of scientists — involve us more, perhaps, than any other group in the world.”

— J. Robert Oppenheimer, speech to the Association of Los Alamos Scientists, November 2, 1945

“We have made a thing, a most terrible weapon, that has altered abruptly and profoundly the nature of the world. We have made a thing that, by all standards of the world we grew up in, is an evil thing.”

— J. Robert Oppenheimer, address to the American Philosophical Society, 1945

“I think when you play a meaningful part in bringing about the death of over 100,000 people and the injury of a comparable number, you naturally don't think of that with ease. I believe we had a great cause to do this, but I do not think that our consciences should be entirely easy at stepping out of the part of studying nature, learning the truth about it, to change the course of human history.”

— J. Robert Oppenheimer, CBS News interview, 1965

“This open access to knowledge, these unlocked doors and signs of welcome, are a mark of a freedom as fundamental as any. They give a freedom to resolve difference by converse, and, where converse does not unite, to let tolerance compose diversity.”

— J. Robert Oppenheimer, on the Institute for Advanced Study

“A tissue of lies.”

— J. Robert Oppenheimer, describing the Chevalier incident at the 1954 hearing
