Günter Wallraff was born in 1942 and lives and works in Cologne. After completing a bookselling apprenticeship, he was forced by the Bundeswehr to do military service for ten months. He then worked in various companies and wrote a book about his experiences, Industriereportagen ( Industrial Reports , 1966). Several book publications followed, sometimes resulting in court martials or even imprisonment. Wallraff caused a sensation in 1977 with undercover research at the editorial offices of the German tabloid Bild ( Der Aufmacher/Lead Story ). His report on the inhuman treatment of migrant contract workers, Ganz unten ( Lowest of the Low , 1985), was the most successful post-war non-fiction title in Germany with over 5 million copies sold. The book was translated into 38 languages.
