In a hundred-year period, a handful of men and women changed the way we see the world. Many of them are well known, such as Marx, Freud, Proust, Einstein and Kafka. Others have vanished from collective memory despite their enduring importance in our daily lives. Without Karl Landsteiner, for instance, there would be no blood transfusions or major surgery. Without Rosalind Franklin, genetic science would look very different. Without Fritz Haber, there would not be enough food to sustain life on earth. What do these visionaries have in common? They all had Jewish origins. Norman Lebrecht has devoted half of his life to pondering and researching the mindset of the Jewish intellectuals, writers, scientists and thinkers who turned the tides of history and shaped the world today as we know it.
