Petroleum from Coal shows why and how Friedrich Bergius and Franz Fischer and Hans Tropsch in 1913-26 invented and developed synthetic fuel processes; explains why and how Matthias Pier at BASF- IG Farben and Otto Roelen at Ruhrchemie successfully industrialized the syntheses during the Nazi-World War II years; and analyzes the pre- and post-World War II vicissitudes of the synthetic fuel industry. The research of Germany's scientists in the 1920s-40s made them world leaders in synthetic fuel studies. Information on the synthetic fuel processes has come from the Allied teams who went to Germany and Japan during World War II's closing months and from British, American, and Canadian synthetic fuel investigations.
