Ilya Grigoryevich Ehrenburg (Russian: Илья Григорьевич Эренбург) was a Soviet writer, journalist, translator, and cultural figure. Ehrenburg is among the most prolific and notable authors of the Soviet Union; he published around one hundred titles. He became known first and foremost as a novelist and a journalist - in particular, as a reporter in three wars (First World War, Spanish Civil War and the Second World War). His articles on the Second World War have provoked intense controversies in West Germany, especially during the sixties. The novel The Thaw (Оттепель) gave its name to an entire era of Soviet cultural politics, namely, the liberalization after the death of Joseph Stalin. Ehrenburg's travel writing also had great resonance, as did to an arguably greater extent his autobiography People, Years, Life, which may be his best known and most discussed work. The Black Book, edited by him and Vassily Grossman, has special historical significance; detailing the genocide on Soviet citizens of Jewish ancestry, it is the first great documentary work on the Holocaust. In addition, Ehrenburg wrote a succession of works of poetry.
