W. Eugene Smith was a master of the photojournalism essay. I became aware of his work in doing research on the Battle of Saipan in which my father fought. Smith was there and documented the aftermath of the Japanese banzai attack on July 7, 1944. There were other photos that he took on Saipan of the interaction between U. S. soldiers and the local children. After the war, Smith documented the effects of mercury pollution in Japan in his essay Minamata.
At first glance this scene might appear to be taken right out of a Cold War spy movie (Cologne On The Rhine – Köln Am Rhine). Two men meeting by the Rhine river in sight of the Cologne Cathedral in Cologne, Germany. Maybe they are about to make some sort of an exchange?
