He returned to Nagasaki the following day and, despite his wounds, returned to work on 9 August, the day of the second atomic bombing. That morning, while he was being told by his supervisor that he was "crazy" after describing how one bomb had destroyed the city, the Nagasaki bomb detonated. Read more on Wikipedia
