Gynecologic Oncologist and Researcher
Physician who discovered the link between DES exposure and clear cell adenocarcinoma in daughters of women who took the drug during pregnancy
Arthur L. Herbst (1926-2020) was an American gynecologic oncologist at the University of Chicago who, in 1971, published the landmark study in the New England Journal of Medicine establishing the causal link between maternal diethylstilbestrol (DES) use during pregnancy and the development of clear cell adenocarcinoma of the vagina and cervix in their daughters. This discovery was groundbreaking because it demonstrated that in utero drug exposure could cause cancer decades later, fundamentally changing the understanding of pharmaceutical teratogenicity. Herbst subsequently established the DES Registry, a comprehensive database tracking health outcomes of DES-exposed individuals across generations. His research ultimately contributed to the FDA ban on DES use in pregnancy in 1971 and shaped modern pharmaceutical regulation regarding drugs administered to pregnant women. The DES disaster, documented through Herbst and his colleagues research, exposed that pharmaceutical companies had continued marketing DES for pregnancy despite evidence of its ineffectiveness dating back to 1953.
