We are living now, not in the delicious intoxication induced by the early successes of science, but in a rather grisly morning after when it has become apparent that what triumphant science has done hitherto is to improve the means for achieving unimproved or actually deteriorated ends.
... a point well demonstrated in the checkered career of one man:
Gaseous nitrogen combines with gaseous hydrogen in simple quantitative proportions to produce gaseous ammonia.
The field of scientific abstraction encompasses independent kingdoms of ideas and of experiments, and within these, rulers whose fame outlasts the centuries. But they are not the only kings in science. He also is a king who guides the spirit of his contemporaries by knowledge and creative work, by teaching and research in the field of applied science, and who conquers for science provinces which have only been raided by craftsmen.
~ Haber (memorial remarks on his mentor, Professor Georg Lunge, in January 1923)
The effects of the successful gas attack were horrible. I am not pleased with the idea of poisoning men. Of course the entire world will rage about it first and then imitate us. All the dead lie on their backs with clenched fists; the whole field is yellow.
~ Rudolph Binding (1867-1938) (on the first German gas attack, April 1915, in A Fatalist at War, 1915)
War and its horrors, and yet I sing and whistle...
~ Confederate General George E. Pickett (1825-1875) (letter to his wife, May 1864)
Today is the anniversary of the birth of German physical chemist Fritz Haber (wiki) (1868-1934), who received the Nobel prize for chemistry in 1918 for his role in inventing the Haber-Bosch process for "fixing" nitrogen on an industrial scale, thus permitting mass production of synthetic fertilizers and high explosives.* Born to a well-to-do Jewish family in Breslau, Prussia, Haber studied chemistry at the Friedrich Wilhelm University in Berlin, eventually receiving a doctorate in 1891.
Unable to find a comfortable working relationship with his father in the latter's Breslau chemical plant, Haber accepted successive academic positions in the universities of Jena and Karlsruhe and developed his nitrogen-fixing process at the latter between 1894 and 1911, while also working on electrochemistry, combustion reactions, and the separation of gold from seawater. When World War I broke out, Haber's process was key to Germany's ability to produce both fertilizer and high-explosives despite her inability to import nitrates because of the British blockade. Moreover, as a militant German imperialist who strongly supported the war effort, Haber played a major role in the development of chemical warfare by the Germans in World War I and was primarily responsible - as an army officer - for the weaponization of chlorine gas and its first devastating deployment against Canadian troops in the Second Battle of Ypres in April 1915.**
He was also active in developing gas masks, studying the physiological effects of poison gas, and is still recognized by many as "the father of chemical warfare.*** Between the wars, Haber continued secret work for Germany on poison gas weapons, but with the coming to power of the Nazis in 1933, his Jewish ancestry told against him (despite an earlier conversion to Lutheranism), and he removed himself to Switzerland, where he died in 1934, a strange, enigmatic man... In his The Void of War, 1918, English writer Reginald Farrer (1880-1920) noted,
"Even in theory, the gas mask is a dreadful thing. It stands for one's first flash of insight into man's measureless malignity against man."
* N.B. Although atmospheric nitrogen is plentiful, it is relatively inert and difficult to coax into forming compounds. The Haber-Bosch process converts atmospheric nitrogen to ammonia by a reaction with hydrogen using a metal catalyst and high temperatures and pressures. The ammonia is used in turn for manufacturing synthetic fertilizers or to produce the nitric acid needed for explosives. Thus, the Haber-Bosch process is one of the most important - and beneficial - industrial procedures ever devised.
** A detailed account of Haber's role in the first deployment of poison gas at 2nd Ypres is provided by Diana Preston in her recent book, A Higher Form of Killing, which treats "the six weeks in World War I that forever changed the nature of warfare." (Preston also treats the sinking of the Lusitania and the first Zeppelin bombing raids on London, all in April/May 1915.)
*** Haber's first wife, who was strongly opposed to his work on chemical weapons, committed suicide within two weeks of their first use at 2nd Ypres. His award of the Nobel prize was bitterly opposed by the Allied nations.
What an extraordinarily mixed legacy - more here on the benefits to the world of the ability to fertilize crops with artificially produced ammonia. SciShow has an excellent brief video on Haber's inventions, good and bad:
Mental Floss has a series of posts covering the events of the WWI exactly 100 years after they happened - the excerpt below is from April 22, on the anniversary of the second battle of Ypres, but you should read the whole thing:
Unsurprisingly, after a few minutes of this the French soldiers fled their trenches in terror. Harold Peat, a Canadian private in reserve in the eastern part of the salient, witnessed the first moments of this new horror in war:
In the far distance we saw a cloud rise as though from the earth. It was a greeny-red color, and increased in volume as it rolled forward. It was like a mist rising, and yet it hugged the ground, rose five or six feet, and penetrated to every crevice and dip in the ground. We could not tell what it was. Suddenly from out the mist we men in reserves saw movement. Coming towards us, running as though Hell as it really was had been let loose behind them, were the black troops from Northern Africa. Poor devils, I do not blame them. It was enough to make any man run.Another Canadian soldier in the front line, Reginald Grant, painted a similar picture:
The line trembled from one end to the other, as the Algerian troops immediately on our left, jumped out of their trenches, falling as they ran. The whole thing seemed absolutely incomprehensible until I got a whiff of the gas. They ran like men possessed, gasping, choking, blinded and dropping with suffocation. They could hardly be blamed... The buttons on our uniforms were tinged yellow and green from the gas, so virulent was the poison.
