In 1925, six of Germany's leading chemical companies banded together in a cartel to protect their business from increasing international competition. Twenty years later the directors found themselves on trial at Nuremberg, accused of being 'the magicians who made the fantasies of Mein Kampf come true'. How had this group of leading companies, whose knowledge and expertise were the envy of the world, become Hitler's creature, directly involved in the Holocaust with their experimental IG Monowitz plant at Auschwitz? In this brilliantly researched and compelling book, Diarmuid Jeffreys shines a bright light on IG Farben's Faustian pact with the Third Reich to reveal in shocking detail the story of the original military-industrial complex.
