Editor's Notes
Cholera was thought to be an airborne disease. But John Snow’s theory was that it was waterborne. And so he actually took a map and marked these little Red marks to mark every death from this particular cholera outbreak. And could very visually, quickly, and see that everyone who was dying was dying around this one water pump on Broad Street in London. And so he was able to prove his point by focusing on the where, right? Where are people living who are dying? Showing that it was all around this one water pump, and he was able to convince the city to pull the handle off the pump, which led to the cholera outbreak diminishing.
