    From fertiliser to Zyklon B: 100 years of the scientific discovery that brought life and death

    I t's 100 years since Fritz Haber found a way to synthesise ammonia – helping to feed billions but also to kill millions, and contributing to the pollution of the planet

     

    Haber was an ardent German nationalist. He was happy his invention was used to make explosives and was a fervent advocate of gas weapons. As a result, on 22 April 1915 at Ypres, 400 tons of chlorine gas were released under his direction and sent sweeping in clouds over Allied troops. It was the world's first major chemical weapons attack. Around 6,000 men died. Haber later claimed asphyxiation was no worse than blowing a soldier's leg off and letting him bleed to death, but many others disagreed, including his wife, Clara, herself a chemist. A week after the Ypres attack, she took Haber's service revolver and shot herself, dying in the arms of Hermann, their only son.

    The ironies that afflicted Haber's life continued in death. One of the most effective insecticides he had helped to develop was Zyklon B, which was subsequently used by the Nazis to murder more than a million people, including members of Haber's extended family, including children of his sisters and cousins.
