In 1925 the three leading chemical firms in Germany - BASF, Bayer, and Hoechst - merged, together with some smaller firms, to become IG Farben. IG Farben became like no other firm synonymous for the participation of German industry in the most heinous crimes of the Nazi regime. This book deals in depth with one of IG Farben's leading factories, Hoechst, during the Third Reich. On the basis of archival research, including access to previously inaccessible company records, the author describes and analyzes the relationship between management and employees with the Nazi party and its organizations.
