Soman (GD) 1944

In 1943, German Army recruited Nobel Prize winner (1938) Austrian-German biochemist Richard Kuhn to determine the nerve agent damage cause mechanism.
He and his research team discovered the nerve agent blocking enzyme – cholinesterase and its operation process. As part of their research, in 1944, Kuhn and colleagues synthesised a new nerve agent, soman, which was twice as good as sarin at inhibiting cholinesterase.

Sarin (GB) 1938

Sarin was the second nerve gas classified as toxic poison, and it was discovered in 1938, by a group of German scientists, while they were attempting to create a pesticide stronger than Triton83. The new agent was named in honour of its discoverers: Schrader, Ambros, Gerhard Ritter, and von der Linde.
