Who identified the Broad Street pump as the source of a cholera outbreak?
Answer
Dr. John Snow
Dr. John Snow conducted critical research in mid-19th century London, where he successfully traced a deadly cholera epidemic to a specific water source, the Broad Street pump. His findings provided essential proof that contaminated drinking water serves as a primary vector for infectious disease outbreaks. This established a foundation for public health interventions long before the widespread adoption of chemical disinfection methods.
