John Snow
Texte du Storyboard
- John Snow was a surgeon who lived in Soho in 1836 onwards, and was London's leading anaesthetist. He was very popular, and as a result, was well respected. He came up with some theories through the time period of 1848-49 and wrote them in "On the Mode of Communication of Cholera". These theories of his included that cholera could not be transmitted by miasma because it affects the lungs not the guts and also the theory that drinking water was being contaminated by the cholera-ridden faeces being disposed of in the cities drains.
- In 1854 cholera broke out in Snow's local area, giving him a chance to investigate further. He created a map called a spot map which showed the deaths in each part of the town. This showed that the residential areas closest to the pump were the ones with the most fatalities, proving his previous theories. This water pump was contaminated by a cracked cesspit a few metres away, which was spreading the cholera.
- Despite his much proof, it took a lot of persuasion just to get the government to change the sewage system, and still many people rejected his ideas. It did have a small immediate impact on the local area because of the government's small actions but years later, his ideas were finally accepted at wider ranges.
