Hans Christian Gerlach is professor of Modern History at the University of Bern. Gerlach is also Associate Editor of the Journal of Genocide Research and author of multiple books dealing with the Hunger Plan, Holocaust and genocide. These include "Krieg, Ernährung, Volkermord: Forschungen zur Deutschen Vernichtungspolitik im Zweiten Weltkrieg" (1998); "Kalkulierte Morde: die Deutsche Wirtschafts- und Vernichtungspolitik in Weissrussland 1941 bis 1944" (1999); "Das letzte Kapitel" (co-authored with and Götz Aly in 2002); and "Sur la conférence de Wannsee" (2002).
Gerlach's article, "Extremely Violent Societies: An Alternative to the Concept of Genocide" has been the subject of great debate among scholars of genocide and violence. In the article, Gerlach challenges the model utilized in trying to understand genocide. Gerlach has previously stirred intense debate among Holocaust historians with his thesis surrounding December 12, 1941 as the date on which Adolf Hitler made the decision to annihilate the Jews of Europe.
Gerlach is also known by his highly critical attitude towards the national conservative resistance in National Socialist Germany. According to Gerlach, the resistance offered by officers such as Claus von Stauffenberg and Henning von Tresckow, who were responsible for the famous assassination attempt on Hitler on 20 July 1944, was insincere, and in fact- Tresckow and many other resistance fighters were heavily implicated in national socialist war crimes  However, Gerlach's thesis was severely criticized by a number of scholars, among them Peter Hoffmann from McGill University and Klaus Jochen Arnold from the Konrad-Adenauer-Stiftung. In 2011, Danny Orbach, a Harvard based historian and PhD candidate, argued that Gerlach's reading of the sources is highly skewed, and, at times, diametrically opposed to what they actually say. In one case, according to Orbach, Gerlach had falsely paraphrased the memoir of the resistance fighter Colonel Rudolf Christoph Freiherr von Gersdorff, and in another case, quoted misleadingly from an SS document. Hence, Orbach concludes that Gerlach's thesis on the German resistance is highly unreliable.
