John Snow is best known for his pioneering work in epidemiology, particularly his investigation of the 1854 cholera outbreak in London. He created a map plotting the locations of cholera cases and discovered a correlation with a contaminated public water pump on Broad Street. By advocating for the removal of the pump handle, he effectively halted the outbreak, demonstrating the importance of sanitation and the spread of disease. His methods laid the groundwork for modern public health and epidemiological practices.
