Dichloro-diphenyl-trichloro-ethane (DDT) is an organo-chlorine insecticide first synthesised in 1874 by the Austrian chemist Othmar Zeidler. Its insect-killing capacity was later realised by the Swiss chemist Paul Muller in 1939.

Although it is readily absorbed through the exo-skeletons of insects, it is poorly absorbed through the skin of mammals.
