Fritz Haber (1868-1934): The Scientist Who Fed the World and Poisoned the Enemy

Scientist Fritz Haber (1868-1934) is regarded as both perpetrator and victim. As professor for chemistry at TH Karlsruhe he succeeded in synthesising ammonia, which made artificial fertilisation possible, the “production of bread from air” in 1909. From 1914 on, Haber—as founding director—put the Kaiser-Wilhelm-Institute for Chemistry and Electrochemistry entirely at the service of war research. This led to the development of explosives and poison gases, which were used for the first time at Ypres on 22 April 1915. Haber’s wife committed suicide, giving rise to the legend that this was a protest against her husband’s work.

Wanted as a war criminal, he briefly fled to Switzerland after the war. In 1919, he was retroactively awarded the Nobel Prize for Chemistry for 1918. The rise of National Socialism brought new concerns. Following the dismissals of Jewish scientists ordered by the Nazi regime, he resigned from his post in protest. He managed to emigrate to England and wanted to help build up science in Palestine, but died on January 30, 1934 during a stopover in Basel.
