In 1934, Peters had written a 3,000-word account of the horrors he had witnessed in Dachau. He described in sickening detail the torture and summary execution of individual prisoners. One prisoner, he reported, “died in my hands a few hours after the beating. All skin was removed from his back, his muscles were hanging down in shreds.” Peters no doubt shared his graphic account of Nazi atrocities with his friends when he arrived on the West Coast. Whether Oppenheimer read Peters’ report on Dachau or merely heard him talk about it, he must have been deeply moved by these stories.
