Joseph Rotblat was interviewed by Harry Kroto in 2002 and 2005.

Born in Warsaw in 1908, Joseph Rotblat has had an incredible career spanning nuclear, radiation and medical physics, and international affairs. He worked on the Manhattan Atomic Bomb project during the second world war and then uniquely, quit the project a few months before the war ended when it became clear that Germany would not be able to develop nuclear weapons of its own for use against the allies.
