Sir Austin Bradford Hill

Sir Austin Bradford Hill was a British epidemiologist and statistician known for his work in public health and establishing ways to determine if a link exists between a potential cause and an effect, such as a risk factor and a disease. He developed a set of nine criteria, called the Bradford Hill criteria, which help researchers evaluate whether a cause-and-effect relationship is likely. His work is especially famous for showing how scientists can infer causality from observational studies, such as linking smoking to lung cancer, and has significantly influenced how we understand disease prevention.
