(pä`o͝ol hĕr`män mŭl`ər), 1899–1965, Swiss chemist, Ph.D. Univ. of Basel, 1925. He worked as a research scientist with J. R. Geigy A.G. in Basel, Switzerland. Muller won the 1948 Nobel Prize in physiology or medicine for discovering (1939) that DDTDDT
or 2,2-bis(p-chlorophenyl)-1,1,1,-trichloroethane, chlorinated hydrocarbon compound used as an insecticide. First introduced during the 1940s, it killed insects that spread disease and fed on crops, and Swiss scientist Paul Müller was awarded the 1948 Nobel Prize

 was an effective insecticide. Although the use of DDT would be banned in the United States in 1972 due to concerns about its impact on the environment, Müller's discovery was hailed as a public-health breakthrough at the time because DDT and products based on it enabled the control of a number of disease-transmitting pests, including lice and mosquitoes.
