Atomic bombs have been dropped twice in history. Tsutomu Yamaguchi survived both of them. Yamaguchi, 93, is the first person to be certified a survivor of both the Hiroshima and Nagasaki bombings. He was in Hiroshima on a business trip on August 6, 1945. After suffering serious burns, he returned the next day to his hometown of Nagasaki, which was bombed three days later. Approximately 210,000 people died in the attacks.
