During World War II, as part of the "Grün 3" program, a plant for the manufacture of the nerve agent tabun was established in Dyhernfurth, producing the nerve agent under the codename "Trilon-83". Run by the "Anorgana GmbH", a branch of IG Farben, the plant began production in 1942. The Germans utilized the forced labour of prisoners of Nazi concentration camps to produce the chemical weapons. Two subcamps of the Gross-Rosen concentration camp – Dyhernfurth I and Dyhernfurth II – were established for this purpose. While the Dyhernfurth I inmates were forced to produce the gas and fill bombs and shells with it, the prisoners of the second camp were primarily forced to work on enlarging the plant.
