The Company That Made Zyklon B
Zyklon-B, a deadly gas, was used by the Nazis to murder over one million people during the Holocaust. Zyklon-B was originally created as a pesticide by the business owned by Bruno Tesch, who knowingly gave it to the Nazis to use on humans. For his misdeeds, he was killed. But the company continued to exist.
The business, which was once known as Degesch and is now known as Detia Degesch, continues to make insecticides. There are worldwide subsidiaries, including one in the United States, in addition to its operations in Germany. Actually, some businesses continue to market Zyklon-B under the trade names Cyanosil, Cymag, and Cyclon.
In case you're interested, the gas is still capable of killing. Frank Atwood was put to death by the state of Arizona in June 2022. He was given the option of receiving a fatal injection or breathing hydrogen cyanide gas. He went with injection.
