1. Searching for the Standing Boy of Nagasaki
A young boy carries on his back the lifeless body of his younger brother, in the devastated city of Nagasaki after the atomic bomb. An American military photographer, Joe O'Donnell, took a picture of him standing stoically near a cremation pit. No one knows the boy's name, but the photo has become an iconic image of the human tragedy of nuclear war. This program follows the continuing efforts to deepen understanding of the photograph, while exploring the fate of thousands of "atomic-bomb orphans" and their struggles to survive the aftermath of World War II.
