HIROSHIMA – After the death of Shigeaki Mori, a Japanese historian known for his research on U.S. prisoners of war who died in the U.S. atomic bombing of Hiroshima in 1945, his wife, Kayoko Mori, 84, took over his research.

“I will follow his will and continue his research,” said Kayoko Mori, who worked with her husband to convey the message that the tragedy of the atomic bombing knew no borders.

On June 3, two and a half months after Shigeaki Mori died at the age of 88, Robert Tatalovich, a 66-year-old bereaved relative of one of the U.S. captives, visited Hiroshima for the first time. Kayoko Mori guided him to a hill on the city’s outskirts where a U.S. military plane crashed, resulting in the capture of his uncle, Joseph Dubinsky, who later died due to the atomic bombing.
