There is a useful
phrase in Texas: a rotating son of a bitch.
This is a bastard who no matter how you turn him—he’s still a son of a
bitch. He’s not shy and there is
generally no confusion about who you are dealing with.
Every now and
then, you run across someone in history who is a just a conundrum and Fritz
Haber was just such a man. His research
might have won him a Nobel Peace Prize but he was also a deeply flawed
individual whose research should also have won him a swift execution after a
trial for international war criminals.
Just a few years
ago, archaeologists discovered evidence of an early example of chemical
warfare. When the Persian Empire
attacked a Roman garrison in modern-day Syria, the Romans began engineering a
surprise attack. So, they began digging
tunnels under their own walls from which they planned to suddenly emerge and
slaughter their attackers.
When the Persians
discovered this, they burned a mixture of coal and sulphur to make a toxic gas
and pumped it into the tunnel. The
Romans died horribly, choking to death in what was—at least so far—the earliest
successful attack with a poison gas.
There was an
earlier gas attack on record (and I’m not talking about some caveman urging his
son to pull his finger). About 2400
years ago, the Spartans attacked Athens, whose inhabitants wisely and promptly
took refuge behind their substantial city walls. The Spartans responded by flinging bundles of
burning wood infused with sulphur over the walls, confident that the noxious
fumes would drive the Athenians out of the city.
Unfortunately,
the concentration of gas was insufficient for the large area of the Greek city,
so that instead of inventing the first lethal chemical weapon, the Spartans had
developed nothing more deadly than the first stink bomb.
Every
scientifically-advanced country signed the Hague Convention in 1899—save the
US, which saw little use in banning weapons about as powerful as strong
pepper. In the dawning age of machine
guns, dreadnoughts, submarines, and long range cannons, concentrating on stink
bombs seemed hypocritical, at best. By
1910, France had developed an effective tear gas. It was not deadly, but was strong enough that
the French police used the gas to force robbers to abandon a bank robbery
attempt. (Note that the Hague Convention
only covered military use, not that of domestic law enforcement.)
In the early days
of World War I, the French lobbed tear gas shells at the Germans, but on the
wide open fields of France, the shells were hardly more effective than the
sulphur the Spartans had used on the Athenians. However, the failed attack touched off
widespread hysteria on both sides of the conflict. When carbon monoxide killed German soldiers in
a barracks, secret—and nonexistent—French weapons were blamed. The Germans vowed to catch up.
Fritz Haber was a
bald Jewish chemist who changed all that.
His research saved millions, perhaps billions of lives because he
figured out a way to cheaply combine nitrogen and hydrogen together to form NH3
or ammonia—the basic ingredient in chemical fertilizers. For the first time, farmers could fertilize
their fields without compost piles, rotting fish, or manure piles. Without chemical fertilizers, it would be
impossible to feed the world’s growing population.
Unfortunately,
this wasn’t Haber’s
goal: Instead of fertilizer, Haber
wanted to build bigger and better bombs.
(Remember the massive explosion at Oklahoma City? Timothy McVeigh used as his basic ingredient
the kind of ammonia based fertilizer that Haber had made possible.)
Though Haber
would have made a vast fortune from his fertilizers during the war, when
Germany offered him the chance to head its gas weapon division, the middle-aged
Haber eagerly accepted and the Kaiser himself made the scientist a Captain of
the German Army. His wife, Clara, was
less than pleased. Holding a Ph.D. in
chemistry herself, she refused to work on the weaponization of gases. Haber didn’t listen to his wife's objections,
simply replacing her in the lab with less principled chemists.
Haber personally
supervised the first test of Germany’s new weapon against British troops. Just as in ancient Athens, the wind dispersed
the gas. The only difference was that
this time, the gas was so ineffective that the British soldiers didn’t even
realize they had been attacked. The
German military high command remained undeterred and decided to devote even more
resources to this weapon. The next test,
far larger, was staged against the Russians on the eastern front. This attack, too, failed when the deadly
liquid froze before it could vaporize into gas.
Haber personally
observed the results and decided to reformulate the gas, switching from bromine
as the base to chlorine, thus making the gas far more deadly. Frankly, the effects of chlorine gas are
truly gruesome: The skin of its victims
turns yellow, green, and black while their eyes glass over with cataracts. The soldiers struggle to breathe as their
lungs fill with fluids, so that these unfortunate victims eventually literally
drown.
Haber not only
perfected the chlorine gas weapons, but he personally supervised the first
successful gas attacks in history near Ypres, in Belgium. On April 22, 1915, Germany released 168 tons
of chlorine gas along a 4-mile front.
One British officer later recorded his observations:
Just
at dawn they opened a very heavy fire, especially machine-gun fire, and the
idea of that was apparently to make you get down. And then the next thing we
heard was this sizzling – you know, I mean you could hear this damn stuff
coming on – and then saw this awful cloud coming over. A great yellow,
greenish-yellow, cloud. It wasn’t very high; about I would say it wasn’t more
than 20 feet up. Nobody knew what to think. But immediately it got
there we knew what to think, I mean we knew what it was. Well then of course
you immediately began to choke, then word came: whatever you do don’t go down.
You see if you got to the bottom of the trench you got the full blast of it
because it was heavy stuff, it went down.
Haber was
unconcerned about the horrors of what he had created, saying on more than one
occasion, “A death is a death.” By this,
he meant that it was relatively unimportant how you died—in other words, that a
slow death by asphyxiation was no worse than being shot. That this—inhumane killing (if there can be
any killing in war that can be called "humane")—was the whole point
of The Hague Convention was evidently irrelevant to him. Somehow, in his spare time, he also managed
to work out what today is called Haber’s Rule—a mathematical table correlating
the concentration of gas with the necessary exposure time to assure a
fatality. Only a true monster could
quantify murder like a golf score.
If Haber was
unconcerned about his activities, quite the opposite could be said of his wife,
Clara, who had become increasingly horrified about the work her husband was
conducting. After the Ypres attack,
Fritz returned home to host a dinner party to celebrate the effectiveness of
the new weapon. Worse yet, Clara learned
that he was to journey to the eastern front the next day in order to conduct a
similar test against the Russians. After
arguing heatedly with her husband, Clara took his military service pistol and
shot herself in the heart. Her body was
discovered out in the garden by their thirteen-year-old son, Hermann.
If Dr. Haber
was upset, he didn’t show it: He left
for the eastern front the next morning without even making any funeral
arrangements for Clara and would remarry before the end of the war.
The postwar
years were something of a mixed bag of successes and failures for the
scientist. He won the Nobel Prize in
Chemistry in 1918, and he was almost immediately charged with being an
international war criminal. Although he
was able to avoid prosecution, he was deeply criticized by the international
scientific community for his wartime actions.
Haber spent
years unsuccessfully trying to extract gold from seawater and he was equally
unsuccessful in his attempt to become head of the Soviet Union's chemical
warfare research. His only real success
was in developing an effective insecticide that could be used on large amounts
of grain before shipment.
Clara and
Fritz’s son, Hermann escaped from Nazi Europe to the US, but shortly afterward
committed suicide, as did Hermann’s daughter shortly after the Second World War. Fritz’s second wife divorced him, but their
son, Ludwig Fritz Haber became a prominent historian of chemical warfare,
producing a book, The Poisonous Cloud, about the use of gas in the First World
War.
When Hitler
came to power, Fritz Haber found he could no longer stay employed at the
university because he was a Jew—this despite his being a decorated war
hero. He died in 1934, on his way to
refuge in England. Unfortunately, his
insecticide work was continued in Germany after his death: That insecticide, known as Zyklon gas, would
be used by Hitler to kill millions--including many of Dr. Haber’s relatives.

Normally, I would never force comments to be moderated. However, in the last month, Russian hackers have added hundreds of bogus comments, most of which either talk about Ukraine or try to sell some crappy product. As soon as they stop, I'll turn this nonsense off.
