Madame Tussauds defended a decision to include a wax likeness of Hitler in its new museum, scheduled to open in Berlin in July. Mayor Klaus Wowereit of Berlin had urged the museum to consider carefully whether to include Hitler and, if it did, to make sure that he not be depicted as a cult figure. The museum argued that it would not make sense to ignore Hitler’s role in German history. His rule “stands for an important, though also appalling, turning point in the development of modern Europe,” the museum said.
