The History of Cyanide
In 1782, while experimenting with the pigment Prussian Blue, the Swedish chemist Carl Wilhelm Scheele discovered Hydrogen Cyanide. Prussian Blue pigment had been known since 1704, but the structure of the chemical was still unknown. The chemical Scheele discovered was known as Blausäure, or "Blue Acid," but was known in English as Prussic Acid.
Hydrogen Cyanide is a dangerous gaseous poison. It was used as a chemical weapon in World War I. In the second world war, it was used in the form of Zyklon B in Nazi death camps. It also may have been used in the Iran-Iraq war against a Kurdish city in Northern Iraq.
