A. Bradford Hill

A. Bradford Hill was a British epidemiologist known for his significant contributions to public health and the study of causation in medicine. He is best recognized for the "Bradford Hill Criteria," a set of principles that help determine whether a relationship between a potential cause and an effect is likely to be causal. These criteria are widely used in epidemiology to assess the strength of evidence in studies, such as those linking smoking to lung cancer. Hill's work has greatly influenced how researchers evaluate health risks and establish connections between exposures and diseases.
