Professor Sir Joseph Rotblat made significant contributions to nuclear physics and worked on the development of the atomic bomb. He walked out of the Manhattan Project after working there for less than a year, the only scientist to do so. Rotblat gave a comprehensive account of his time at Los Alamos. His Archive is now becoming available and papers contained therein are inconsistent with some aspects of his account. The reasons as to how such anomalies and contradictions could occur are considered.
