John Snow’s water pump, Soho | Almost directly behind Oxford street, on Broadwick street sits John Snow’s Water Pump. A cholera epidemic swept Soho in 1854, killing 500 people in a few months. John Snow (the physician, not the Game Of Thrones character) figured out that the water pump was the source of the outbreak, so had the handle removed. The cases of cholera declined and the outbreak ended.
John Snow-Father of Epidemiology-Cholera Outbreak This picture shows the man that is one of the fathers of Epidemiology. His research has inspired essential changes in the water and waste system in his city of London. This led to improvement of better hygiene and public health.
Robin painstakingly georeferenced every cholera death and pump location, so we could recreate the map on a modern layout of London. We wondered what would happen if we tried to recreate the map using a modern tool, opting to try CartoDB, using the the lovely Stamen 'toner' projection to at least keep the background in common with Snow's London.
