Fritz Haber was a German chemist, remembered for his groundbreaking work on nitrogen fixation but also for his role in developing chemical weapons. The Haber-Bosch process, his most famous invention, enabled the large-scale production of ammonia-based fertilizers. This dramatically increased agricultural yields, feeding billions. However, during World War I, Haber also pioneered the use of chlorine gas and other toxic agents in warfare. He stands as a complex figure, a genius whose discoveries both sustained and destroyed. He is like a historical figure embodying a fundamental moral contradiction.
