I was at Hiroshima in early 1952. I had gone to a supply specialist school on Eta Jima and had taken the ferry to Hiroshima on 3 different weekends. I have many pictures and remembrances of these trips. One I especially remember is a man coming up to me on the main street, turning around and showing me his back that was horribly burnt. He then turned back to me and showed me an old LIFE magazine photo of him with burnt skin hanging in shreds. Then, he handed me a card which read "K. K. Kikura - Number One Atom Bomb Sufferer" and wanted to sell me an autographed card. A friend of mine who was second in command of the Lawrence Livermore Laboratory, under Dr. Teller, told me that I may have gotten enough radiation in those all day visits to make it impossible for me to have children and we finally after 10 years of marriage, adopted a boy who is now 40 years old.
