AI Summary
5 min readOn April 22, 1915, near the Belgian town of Ypres, French and Algerian troops watched an enormous greenish cloud drift across no man’s land. Leaves withered on trees as it passed. Birds fell from the sky. When the cloud reached the men, they fell to the ground convulsing, their skin turning blue as they suffocated. In less than ten minutes, roughly a thousand soldiers were dead and four thousand more wounded. The weapon was chlorine gas, and watching its first large-scale use was its inventor, Fritz Haber. He would become known as the father of chemical warfare. Yet the same man also developed a process that, by one estimate, now sustains half the world’s population. His story is one of profound contradiction: a scientist who saved humanity from famine and then turned his genius toward mass killing.
