He founded the Epidemiological Society of London in 1850, the first organization dedicated to studying not just cures for disease, but also their causes. And so when cholera returned in 1854, John Snow saw a chance to finally prove his theory and set about studying the patterns of disease. The disease appeared to strike randomly, both rich and poor, but he realized that in his district were two different water companies, one of which he theorized might be contaminated. Finding evidence proved more difficult than he anticipated: going to door to door, he was often met by people who didn't even know what water company supplied their building. He tracked down landlords and even developed a water test to help him identify which water source each house had, but before he had the time to compile and analyze his findings, another terrible outbreak struck in Broad Street. ____________ Get the intro music here! http://bit.ly/1EQA5N7 *Music by Demetori: http://bit.ly/1AaJG4H Get the outro music here! http://bit.ly/1iYzuEx *Music by Sean and Dean Kiner: http://bit.ly/1LBy9zh

Hallowed are the Ori and the Extra Credits & History

This is one of those people I feel like I should have heard of before. Also, forgetting the disease aspect, why would it ever be seen as a good idea to drink water downstream of sewage? I mean, the taste alone should have stopped that i'd have thought

Understanding how truly ignorant and destitute people were even as recently as the 1800's is becoming more and more impossible.

The people of the time knew the water tasted bad; so, they would mix it with something else, like wine, to hide the taste. For the most part people drank wine and small beer. Water was primarily used for cooking, washing, and cleaning.

As John Snow discovered, the average housedweller didn't really understand where their water was coming from beyond "this well" or "that pump".

Also, that is the reason so many people drank large amounts of beer every day. They didn't know it, but fermentation kills most of the microbes, and they could see the result. The daily ration for a sailor in the British Royal Navy in the 1700's was 4½ litres of beer and a quarter liter of rum, since their drinking water would be contaminated within a week or two. However, it is also worth remembering that this beer was significantly weaker than what we are used to today, only 1-2 percent alcohol or less, as compared to 5% or more in most beer you can buy today.

Audio glitch at ~5s into the video again.

As I am doing my thesis within pharmaceutics, I must say I admire John Snow's dedication. It's not easy trudging through false-positives and undesired results combined with inadequate information, equipment and time without getting discouraged. Yet persist Snow did, makes me wish I had his diligence and stuborness.

We're actually going to talk a bit about how good sanitation infrastructure was implemented in cities, and it was really a mind-boggling accomplishment. But in earlier eras, as the cities grew and people were really just concerned with placing their houses somewhere, a lot of things really got shunted together in whatever way seemed most workable. And everyone else who commented did a great job of exploring how they lived with those conditions for so long. :D

Wait is this the one where there was a case across town that didn't seem connected to the pump that ends up being a woman who used to live on that street and liked the taste of the water so she had a relative bring her whole bottles of the stuff to her new place? or is this a different pump >.>?

Excellent, but the chemical formula for salt is NaCl not Na as shown at 4:32.
