Question: Konrad Kujau was a German illustrator and forger who became famous for selling the Hitler Diaries to what weekly news magazine in Hamburg, Germany?
Context: The Hitler Diaries (German: "Hitler-Tagebücher" ) were a series of sixty volumes of journals purportedly by Adolf Hitler, but forged by Konrad Kujau between 1981 and 1983.  The diaries were purchased in 1983 for 9.3 million Deutsche Marks (£2.33 million or $3.7 million) by the West German news magazine "Stern", which sold serialisation rights to several news organisations.  One of the publications involved was "The Sunday Times", who asked their independent director, the historian Hugh Trevor-Roper, to authenticate the diaries; he did so, pronouncing them genuine.  At the press conference to announce the forthcoming publication, Trevor-Roper announced that on reflection he had changed his mind, and other historians also raised questions concerning their validity.  Rigorous forensic analysis, which had not been performed previously, quickly confirmed that the diaries were fakes. Konrad Paul Kujau (27 June 1938 – 12 September 2000) was a German illustrator and forger.  He became famous in 1983 as the creator of the so-called Hitler Diaries, for which he received DM 2.5 million from a person who in turn sold it for DM 9.3 million to the magazine "Stern".  The forgery resulted in a four-and-half year prison sentence.
