WASHINGTON: Last December, Rebecca Erbelding, a young archivist at the United States Holocaust Memorial Museum, opened a letter from a former United States Army intelligence officer who said he wanted to donate photographs of Auschwitz he had found more than 60 years ago in Germany.

The comparisons between the albums are both poignant and obvious, as they juxtapose the comfortable daily lives of the guards with the horrific reality within the camp, where thousands were starving and 1.1 million died.

For example, one of the Höcker pictures, shot on July 22, 1944, shows a group of cheerful young women who worked as SS communications specialists eating bowls of fresh blueberries. One turns her bowl upside down and makes a mock frown because she has finished her portion.
