The official estimate of 78,000 victims, of those 59,000 Jews, was determined in 2005 by Tomasz Kranz, director of the Research Department of the State Museum at Majdanek, calculated following the discovery of the Höfle Telegram in 2000. That number is close to the one currently indicated on the museum's website. The total number of victims has been a controversial topic of study, beginning with the research of Judge Zdzisław Łukaszkiewicz in 1948, who approximated a figure of 360,000 victims. It was followed by an estimation of around 235,000 victims by Czesław Rajca (1992) of the Majdanek Museum, which was cited by the museum for years. The current figure is considered "incredibly low" by Rajca, nevertheless it has been accepted by the Museum Board of Directors "with a certain caution", pending further research into the number of prisoners who were not entered into the Holocaust train records by German camp administration. For now, the Museum informs that based on new research, some 150,000 prisoners arrived at Majdanek during the 34 months of its existence. Of the more than 2,000,000 Jewish people killed in the course of Operation Reinhard, some 60,000 Jews (56,000 known by name) were most certainly exterminated at Majdanek, amongst its almost 80,000 victims accounted for, altogether.
