Bombs and Fertilizer

The breakthrough came in 1909, when Fritz Haber, a German-Jewish chemist, developed a technique for synthesizing ammonia, a nitrogen compound. By 1914, the experimental technique had become industrially viable, and in that year Haber’s method, called the Haber–Bosch process, yielded as much reactive nitrogen as the entire Peruvian guano trade. The

The Haber–Bosch process is the most important chemical discovery of the twentieth century. By doubling the amount of disposable nitrogen, it provoked the demographic explosion that took the human population from 1.6 to 7 billion in fewer than one hundred years. Today, nearly fifty per cent of the nitrogen atoms in our bodies are artificially create

The night gardener told me that the man who invented modern-day nitrogen fertilizers—a German chemist called Fritz Haber—was also the first man to create a weapon of mass destruction, namely chlorine gas, which he poured into the trenches of the First World War. His green gas killed thousands and made countless soldiers claw at their throats as the
