The German Who Saved 4 Billion People... and Killed Millions

What connects bird poop, the food on your plate, and the battlefields of World War One? The answer is nitrogen—and one brilliant, deeply controversial chemist named Fritz Haber. You’ll discover why nations competed for guano-covered islands and why plants cannot use the nitrogen surrounding them. You’ll see how the Haber-Bosch process pulled fertilizer from the air and transformed global food production. Then you’ll follow the darker side of Haber’s legacy: explosives, poison gas, and his failed attempt to extract gold from seawater. By the end, you’ll understand how one scientific breakthrough became both a lifeline and a weapon.
