Zyklon b was used as a fumigant before it was used in the holocaust. It was also called Prussic acid and would be known as Hydrogen Cyanide today. It was discovered by Carl Scheele back in the 1700s. It is also what gives poisonous (bitter) almonds their characteristic scent and toxicity.
Haber did however, suggest the use of Chlorine gas as a chemical weapon which his wife was so horrified by that she committed suicide. Haber was also partially responsible for the development of the Born Haber cycle which is a theoretical tool used to estimate the thermodynamic stability of salts.
Haber is only listed here because ultimately billions would have starved to death without the Haber process. And regardless of his intentions and the other things he did, that particular invention arguably saved more lives than anyone else that has ever lived.
Thank you for providing context. I did not mean to blame (or make people think that) Haber for any deaths, he was a smart person that made a great impact on all of us. It isn't his fault people think of other ways to use his work for death. It most have been hard on him to have his wife commit suicide over it though. That's rough.
Haber did not develop the Haber process to produce fertillizer. He did it precisely because German access to saltpeter from South America had been cut off and that threatened to severely compromise the German capacity for war. This was not a case where Haber's work was meant for benign peaceful purposes and misappropriated for use in war. It was used exactly the way he intended it to be. It just happened to also be useful for keeping half the planet from starving to death. His wife did not kill herself because his work was misused. She killed herself because it was used exactly how Haber wanted it to be. And he can't advocate for the use of Chlorine as a chemical weapon and have clean hands by definition.
Which is why I said that the only reason he was mentioned is because the Haber process ultimately saved the lives of billions of people arguably outweighing the harm that process was developed to enable. Haber wasn't a good guy by any stretch of the imagination but without the Haber process, we would have had famine and death on a scale never seen in all of human history on this planet.
Interesting. Thanks for the explanation. I guess I got mixed up with the process name and his actual intended use.
Even the fertilizer thing is arguably bad. It's allowed the population of the world to explode at an exponential rate and burn through resources even faster rather than be capped at a much more manageable level.
The alternative wasn't a reasonable population, it was billions starving. The solution was, and still is, giving women better control over whether or not they have children.
Even more are going to starve when we run out of fossil fuels and can no longer sustain the agriculture required to feed the now massively inflated population. Not to mention all the other damage having so many more people is doing to the world that is also probably going to kill us even if we solve the resource problem.
