Dichlorodiphenyltrichloroethane Dichlorodiphenyltrichloroethane (DDT) is a colorless, tasteless, and almost odorless crystalline organochlorine known for its insecticidal properties and environmental impacts. First synthesized in 1874, DDT's insecticidal action was discovered by the Swiss chemist Paul Hermann Müller in 1939. DDT was used in the second half of World War II to control malaria and typhus among civilians and troops. Müller was awarded the Nobel Prize in Physiology or Medicine "for his discovery of the high efficiency of DDT as a contact poison against several arthropods" in 1948.
