The Alchemy of Air by Thomas Hager - 8/10
If anyone is not aware of the Haber-Bosch process, they should really learn what it is. It's kind of a big deal. Like, responsible for feeding billions of people, while also indirectly killing millions kind of a big deal.
This book was an overview of the birth of modern fertilizers, largely developed by Fritz Haber and Carl Bosch in WWI era Germany. I would have liked a bit more chemistry and technical details on how the plants work, but this is certainly a good place to start. If you recognize Haber's name, you probably already know that this story is going to get really, really dark towards the end. Bosch's story is equally frustrating, but he at least has the will and the political know-how to stall Germany's ultimate scientific downfall.
