## Resource

One chemist helped turn air into fertilizer for billions of people — and then helped turn the same science toward poison gas. In this episode, we unravel Fritz Haber, the Haber-Bosch process, the rise of synthetic ammonia, and the grim birth of chemical warfare. Listen now to hear how one invention could feed the world and reshape war at the same time. Fritz Haber’s story is one of science’s biggest double edges: the ammonia synthesis behind the Haber-Bosch process helped make fertilizer at industrial scale and feed billions, but the same chemistry also fed explosives and chemical warfare. In this episode, we unpack how one chemist changed global agriculture, war, and the ethics of scientific progress. • The Haber-Bosch process turned atmospheric nitrogen into ammonia, transforming fertilizer production and modern food systems. • That same industrial chemistry also helped Germany produce nitrates for explosives during World War I. • Fritz Haber became a central figure in chemical warfare, including the first large-scale chlorine gas attacks. • His legacy still shapes debates about dual-use science, scientific responsibility, and technology ethics.
