Prophets Without Honor by Frederic V. Grunfeld

One of the best books about Jews in Germany/Austria between the two wars and a good way to know some of the extremely rich life that existed then.
Hard to put down. – You should be able to find a used copy somewhere.

The horrible atrocities of the Nazi war machine of the 1930s and 1940s, including the brutal persecution and murder of millions of Jews, are by now well documented. But rarely discussed is the equally vicious assault the Nazis made upon Jewish intellectual achievements. The century leading up to Hitler’s rise to power was one in which German-Jewish thinkers flourished, producing an immense outpouring of literature, music, and ideas. It was a golden age in intellectual history, second only to the Italian Renaissance.
Prophets without Honour is the collective biography of some of the era’s extraordinary minds–Kafka, Einstein, Mahler, and Freud, as well as many lesser known, though by no means less important or impressive, thinkers, such as Walter Benjamin, Carl Sternheim, and Else Lasker-Schuler. Weaving together each of their stories into a colorful mosaic, Grunfeld brings these thinkers and their world to life, citing anecdotes that make evident their frustration and their pain.
