"Why the arrest?" smh
Victor Klemperer (I Will Bear Witness 1933-41: A Diary of the Nazi Years) relates a episode late in the war. He was among the last few Jews still alive in Dresden, working in a munitions factory and living in barracks with other Jewish workers. One morning he walked into the communal kitchen and overheard a discussion about a co-worker who had been arrested overnight by the Gestapo. One of them said "what did he do? He must have done something wrong. They wouldn't just pick him up for no reason. This, after thousands had already been rounded up.
The publication of Victor Klemperer's secret diaries brings to light one of the most extraordinary documents of the Nazi period. I Will Bear Witness is a work of literature as well as a revelation of the day-by-day horror of the Nazi years.
A Dresden Jew, a veteran of World War I, a man of letters and historian of great sophistication, Klemperer recognized the danger of Hitler as early as 1933. His diaries, written in secrecy, provide a vivid account of everyday life in Hitler's Germany.
What makes this book so remarkable, aside from its literary distinction, is Klemperer's preoccupation with the thoughts and actions of ordinary Germans: Berger the greengrocer, who was given Klemperer's house ("anti-Hitlerist, but of course pleased at the good exchange"

, the fishmonger, the baker, the much-visited dentist. All offer their thoughts and theories on the progress of the war: Will England hold out? Who listens to Goebbels? How much longer will it last?
This symphony of voices is ordered by the brilliant, grumbling Klemperer, struggling to complete his work on eighteenth-century France while documenting the ever- tightening Nazi grip. He loses first his professorship and then his car, his phone, his house, even his typewriter, and is forced to move into a Jews' House (the last step before the camps), put his cat to death (Jews may not own pets), and suffer countless other indignities.
