Few figures of the modern age embody both human brilliance and moral contradiction like Fritz Haber (1868–1934), the German chemist whose discoveries shaped the twentieth century. Born into a Jewish family in Breslau and driven by a fierce desire to serve his nation, Haber achieved what had eluded scientists for centuries, a method to pull nitrogen from the air and turn it into ammonia, the foundation of modern fertilizer. His process fed billions and earned him the Nobel Prize.

But the same mind that gave life to the fields also brought death to the trenches. During the First World War, Haber directed Germany’s first use of chemical weapons, unleashing chlorine gas on the Western Front. To him, it was a scientific duty; to history, it was a moral tragedy.

In this episode of The History in Motion Podcast, we follow Haber’s rise from university lecturer to national hero, his complicity in the horrors of war, and his final years marked by exile, guilt, and loss, including the suicide of his wife, Clara, herself a chemist who condemned his work.

Was Fritz Haber a saviour of humanity, a servant of empire, or a man destroyed by his own creation? Join us as we unravel the life and legacy of the chemist who fed the world and poisoned it.
