Dr. John Snow: Cholera Map of London, 1854 Poster
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 the City of Westminster, London, England, and occurred during the 1846–1860 cholera pandemic happening worldwide. This outbreak, which killed 616 people, is best known for the physician John Snow's study of its causes and his hypothesis that germ-contaminated water was the source of cholera, rather than particles in the air. This discovery came to influence public health and the construction of improved sanitation facilities beginning in the mid-19th century. Snow's endeavor to find the cause of the transmission of cholera caused him to create this incredible map showing that cholera deaths centered around the Broad Street water pump. This map is a faithful reproduction of Dr. Snow's original map. You will love the crisp detail and the story told by this amazing map.
