That was Tsutomu Yamaguchi who was a survivor of both the Hiroshima and Nagasaki atomic bombings during World War II. Although at least 160 people are known to have been affected by both bombings and he is the only person to have been officially recognized by the government of Japan as surviving both explosions. He was in Hiroshima the day the first bomb was dropped and he was injured by the blast and had major traumas and burns. He went to Nagasaki to recover and three days later, he was again injured by the second bomb.
