The topic revolves around Fritz Haber, a German chemist recognized for winning the Nobel Prize in Chemistry in 1918 for inventing the Haber–Bosch process, a method crucial for synthesizing ammonia and producing fertilizers and explosives. Despite being celebrated for his contributions to agriculture and industry, Haber’s legacy is tainted by his role as the « father of chemical warfare » during World War I, where he pioneered the use of chlorine gas. His work indirectly contributed to the creation of Zyklon B, infamously used in the Holocaust. The video explores the dichotomy of Haber’s scientific achievements and the darker aspects of his legacy, ultimately leading to his forced resignation in the face of Nazi persecution and his tragic death in 1934.
