Great post! Thanks for your effort.

About the story of the map, there is another version. According to Orford [1], Dr Snow enquired ¨…where the people who had died had obtained their drinking water. He quickly isolated the Broad Street pump as the likely source of the outbreak, and he got the handle of the pump removed.

Dr Snow actually drew his map of cholera some time after the epidemic had abated and definitely after the handle of the pump had been removed. The map formed part of a report written by Dr Snow.”

I fouhd this amazing, especially because I always was told the other version.
