In September 2003, Jens Bisky (a German literary editor) identified the anonymous author as journalist Marta Hillers, who had died in 2001. Revelation of Hillers' identity brought controversy in the literary world. Her publisher Enzensberger was angry that her privacy had been invaded. He did not accede to requests by journalists to review the writer's original diary materials. Writing in the Berliner Zeitung, Christian Esch said that if the work were to be fully accepted as authentic, people had to be able to examine the diaries. He said the book's text indicated that changes were made between the initial handwritten diaries and the typed manuscript. It had been translated into English and published for the first time nearly a decade after the events, in 1954 in English and in 1959 in German. He noted there were minor discrepancies between editions.[16]
Prior to republication of the diary in 2003, Enzensberger had hired Walter Kempowski, an expert on diaries of the period, to examine Hillers' "original notes and typescript"; he declared them authentic. After questions from journalists, Enzensberger released Kempowski's report in January 2004. Kempowski had noted that the author's version of events was supported by numerous other sources. He noted that Hillers had added material to the typescript and the published book that were not found in the diary, but editors and critics agree this is a normal part of the revision and editing process.[17]
Antony Beevor, a British historian who wrote a 2002 work on the Battle of Berlin, affirmed his belief in the book's authenticity when it was published in English in 2005. He said it conformed to his detailed knowledge of the period and other primary sources he has used.[3][18][19] Beevor wrote the introduction to the new 2005 English edition of the book.[5][15]
