In March 1968, the toxin under scrutiny was VX, one of the most potent nerve agents in existence. The original compound was created by Ranajit Ghosh, a chemist working at Imperial Chemical Industries. The liquid proved to be an effective pesticide and it was quickly put on the market under the name Amiton. Not long afterwards, however, it was taken off the market for being too toxic to handle safely. The agent’s extreme toxicity drew the attention of government weapons research labs, whose scientists were always on the lookout for more efficient ways to kill people.
