I recently was gifted a book from 1950 by Life magazine. It's called Life's Picture History of World War II. As I was looking through it, I was struck about how little mention of the Holocaust there was in it. In fact, I could only find one paragraph that summarized the camps liberated by US soldiers in 1945. There were no pictures of the camps or liberated prisoners in a book that was full of them.

My question is this: was this normal at the time? If so, why? Were all the facts not fully known even after Nuremberg and other trials?

I feel as though the Holocaust has become central to most narratives and histories about World War II, and it was surprising to see it barely mentioned at all in a book that was published just a few years after the war had ended. If this was normal in 1950, when did that change and what were some of the causes?
