Medical harm can begin in a hospital routine, a medicine’s formulation or a decision about which evidence is enough. These histories follow those decisions and the people affected by them, then examine how practice and oversight changed.
Start with three different questions: how did a ward become safer, why did a familiar drug become a poisonous mixture, and what happened when a reviewer asked for stronger evidence? Each article links the records and research behind its account.
In 1847, Semmelweis introduced chlorine-based hand disinfection in a Vienna maternity clinic, and deaths from childbed fever fell sharply.

Frances Kelsey repeatedly sought stronger evidence for the original U.S. thalidomide application despite company pressure. Researchers then linked the drug to severe birth defects.
