A project that raised the ire of many on the left, and which became a central issue of the "Historikerstreit", consisted of two proposed museums celebrating modern German history, to be built in West Berlin and Bonn. Many of the left-wing participants in the "Historikerstreit" claimed that the museum was meant to "exonerate" the German past and asserted that there was a connection between the proposed museum, the government, and the views of such historians as Michael Stürmer, Ernst Nolte, and Andreas Hillgruber. In October 1986, Hans Mommsen wrote that Stürmer's assertion that he who controls the past also controls the future, his work as a co-editor of the "Frankfurter Allgemeine Zeitung" newspaper—which had been publishing articles by Ernst Nolte and Joachim Fest denying the "singularity" of the Holocaust—and his work as an advisor to Chancellor Kohl should cause "concern" among historians.
