John Snow, Broad Street Cholera Map,1854

Scale 30 inches to a mile. A map taken from a report by Dr. John Snow: "Report on the cholera outbreak in the Parish of St. James, Westminster, during the autumn of 1854", presented to the vestry by the Cholera Inquiry Committee, July 1855. The Broad Street cholera outbreak (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.
