During the decade 1945 to 1955 there haven’t been many authors who wrote about the theme of the holocaust and about the racial persecutions operated by the fascist and nazi regime throughout Europe. There may be many reasons for this, and one is certainly the fact that until the end of the war, and the following liberation of Germany and Poland, many didn’t really know, or sometimes they didn’t want to realize, the proportions of the crimes perpetrated inside the concentration camps. It is not too strange that the first authors to reveal them to the public were in fact the same witnesses and victims of the nazi regime, as Primo Levi and Anna Frank, who both wrote their stories basing them on their own direct experience and not on some second hand data. The international cinema began to describe these events only later; in fact the discoveries by the allied forces of the concentration camps constituted such a strong and dramatic occurrence that even the international political community was slow and circumspect to openly and seriously face it. As an evidence of how much this problem revealed itself to be hard to handle, it is maybe important to recall that Se questo è un uomo, by Primo Levi, first published by De Silva during the year 1947 didn’t get to touch a large public until 1958 when Einaudi republished it; and only after 1958, together with the Anna Frank’s Diary and The trial by Peter Weiss, the book could contribute to reveal the experience and the knowledge of the criminal atrocities perpetrated by the nazis, which were by then historically established and documented after the discovery of the concentration camps.
