BOULDER, Colo. — Soviet photojournalists working for the country’s most important newspapers were among the first to document the unfolding Holocaust in their homeland, and they were also witnessing and recording the slaughter of Soviet citizens who, like the photographers themselves, were Jewish. But the extent to which the Nazis targeted Jews was obscured in the dominant Soviet press during World War II and was suppressed in the Cold War era, during which the Soviets dwelled on the depravity of “fascist troops” murdering “peaceful Soviet citizens.” The Soviet Union’s collapse allowed scholars to see a fuller picture of what happened, and to understand the overlapping narratives of Soviets and Jews.
