His manuscript has just been published as “Hiroshima 8:15: The Lost Memoir,” 8:15 referring to the time in the morning the atomic bomb detonated over the city. Because he really expresses his emotions on that, kind of an internal dialogue about the atomic bomb. And he talks about conversations he had with other leaders in Hiroshima about how to commemorate the attacks on Hiroshima and Nagasaki. Kiyoshi Tanimoto, one of six survivors profiled in John Hersey’s book “Hiroshima.”
