The Baddest Elves of History
John Snow, a pioneering 19th-century epidemiologist, revolutionized public health by using spatial mapping to trace the source of London's 1854 cholera outbreak. His innovative mapping of cholera cases around the Broad Street pump demonstrated the power of geographic analysis, laying the foundation for modern Geographic Information Systems (GIS). Snow’s work continues to influence epidemiology and GIS, showcasing the importance of spatial data in solving real-world challenges.
