>>74002731,100,000 to 1,500,000 Sources for this estimate are historians Yisrael Gutman and Michael Berenbaum (later of the U.S. Holocaust Memorial Museum) in their 1984 book, “Anatomy of the Auschwitz Death Camp”; also Dr. Franciszek Piper, the curator of the Auschwitz Museum, writing a chapter in that book. This estimate was later also cited by Walter Reich, former director of the U.S. Holocaust Memorial Museum, writing in The Washington Post on September 8, 1998. The upper figure of 1,500,000 thus remains the "official" figure as now inscribed at Auschwitz, with the earlier figure of 4,000,000 having been removed from the memorial at the site of the former concentration camp.
1,000,000 Jean-Claude Pressac, writing in his 1989 book “Auschwitz: Technique and Operation of the Gas Chambers.” This is interesting since he wrote his book to repudiate so-called "Holocaust deniers" who were called that precisely because they had questioned the numbers of those who had died at Auschwitz.
900,000 Reported on August 3, 1990 11, by Aufbau, a Jewish newspaper in New York.
800,000 to 900,000 Reported by Gerald Reitlinger in his 1953 book, “The Final Solution.” This figure is notable, considering the fact that it reduces the Auschwitz death total from the 4,000,000 figure that was widely in vogue in 1953.
