[PAR] [TLE] John Snow [SEP] John Snow (15 March 1813 – 16 June 1858) was an English physician and a leader in the adoption of anaesthesia and medical hygiene.  He is considered one of the fathers of modern epidemiology, in part because of his work in tracing the source of a cholera outbreak in Soho, London, in 1854.  His findings inspired fundamental changes in the water and waste systems of London, which led to similar changes in other cities, and a significant improvement in general public health around the world. [PAR] [TLE] 1854 Broad Street cholera outbreak [SEP] The Broad Street cholera outbreak (or Golden Square outbreak) was a severe outbreak of cholera that occurred in 1854 near Broad Street (now Broadwick Street) in the Soho district of London, England.  This outbreak, which killed 616 people, is best known for the physician John Snow's study of its causes and his hypothesis that contaminated water, not air, was the source of cholera.  This discovery came to influence public health and the construction of improved sanitation facilities beginning in the mid-19th century.  Later, the term "focus of infection" would be used to describe sites, such as the Broad Street pump, in which conditions are good for transmission of an infection.  John Snow's endeavor to find the cause of the transmission of cholera caused him to unknowingly create a double-blind experiment.
