Kurt Kleemann is leading the town Archive of Remagen, the Roman Museum Remagen and the Peace Museum Bridge of Remagen. You can try his official e-mail k.kleemann@remagen.de (if you didn't already) or call him 0049-2543-201-59 in his Office. He is working together with Wolfgang Gückelhorn who helped me with my documentation about the V1 Launch area here in Lohmar. He just published new findings about the American camp for German POW at the Rhine near Remagen, they could prove that not 1% of the 260,000 German POW died there, even though it was said that some 10,000s died there of hunger and diseases.
There is an interview with Klaus Schultz about his time as soldier in the Huertgen forest online: http://www.mm-historyguide.de/80.0.html
Perhaps you can reach him via info@konejung-stiftung.de who have set up that site. His name is quiet common in Germany, one is a pretty famous intendant and dramatic adviser, so it's hard to google the right one.
