History of Development
The first chemial weapon that was invented was chroline. The element itself was first discovered when Swedish scientist Carl Wilhelm Scheele produced it in 1774. He did this by heating hydrochloric acid with the mineral pyrolusite creating a dense greenish-yellow gas with a choking smell. It was however not called a element until 1810, after British chemist Humphry Davy investinated the gas. Chroline was not used as weapon until Germany decided to in WW1.
The discoveries of the other chemicals were very much similar. Phosgene, for example, was created by Humphry Davy's younger brother, John. He did this by using sunlight to produce the chemical from carbon monoxide and chlorine. Then in 1860, British scientist Mansuete Despeterez became the first man to report the dangers of mustard gas. He found out that when you combine sulfur dichloride and ethylene together, it created a substance that could leave toxic effects on the skin. Finally tear gas was invented when the French put the gas xylyl bromide into grenades.
