When the U.S. government brought the world's greatest scientists together to build the first atomic bomb, nuclear physicist Joseph Rotblat was among them. But his conscience would not allow him to continue, and he became the only member of the Manhattan Project to leave on moral grounds.

Branded a traitor and spy, Rotblat went from designing atomic bombs to researching the medical uses of radiation. Together with Bertrand Russell he helped create the modern peace movement, and eventually won the Nobel Peace Prize. The Strangest Dream tells the story of Joseph Rotblat, the history of nuclear weapons and Rotblat's efforts to halt nuclear proliferation.
