Quizplus · Accepted Answer

John Snow's investigations into cholera outbreaks in London in the mid-19th century are widely regarded as the foundation of modern epidemiology. His careful observations and mapping of cases led him to conclude that contaminated water was the source of the disease, and his work contributed to the development of public health measures to prevent the spread of infectious diseases. While other figures like Louis Pasteur made important contributions to microbiology and germ theory, Snow is particularly noted for his pioneering work in understanding the transmission of diseases and the importance of taking a data-driven approach to public health interventions.
