o,p'-DDT

DDT (from its trivial name, dichlorodiphenyltrichloroethane) is one of the most well-known synthetic pesticides. It is a chemical with a long, unique, and controversial history.First synthesized in 1874, DDT's insecticidal properties were not discovered until 1939, and it was used with great success in the second half of World War II to control malaria and typhus among civilians and troops. The Swiss chemist Paul Hermann Müller was awarded the Nobel Prize in Physiology or Medicine in 1948 "for his discovery of the high efficiency of DDT as a contact poison against several arthropods."[2] After the war, DDT was used as an agricultural insecticide, and soon its production and use skyrocketed.
