Tsutomu Yamaguchi, Japanese engineer and businessman (d. 2010)
Tsutomu Yamaguchi (山口 彊, Yamaguchi Tsutomu) (March 16, 1916 – January 4, 2010) was a Japanese marine engineer and a survivor of both the Hiroshima and Nagasaki atomic bombings during World War II. Although at least 70 people are known to have been affected by both bombings, he is the only person to have been officially recognized by the government of Japan as surviving both explosions.A resident of Nagasaki, Yamaguchi was in Hiroshima on business for his employer Mitsubishi Heavy Industries when the city was bombed at 8:15 AM, on August 6, 1945. He returned to Nagasaki the following day and, despite his wounds, he returned to work on August 9, the day of the second atomic bombing. That morning, while he was being berated by his supervisor as "crazy" after describing how one bomb had destroyed the city, the Nagasaki bomb detonated. In 1957, he was recognized as a hibakusha ("explosion-affected person") of the Nagasaki bombing, but it was not until March 24, 2009, that the government of Japan officially recognized his presence in Hiroshima three days earlier. He died of stomach cancer on January 4, 2010, at the age of 93.
