o 1849: New York Epidemic where the bacteria remained for the next 12 years
o 1854: John Snow determined that the disease was not from miasma, but from contaminated water
o 1858: “Great Stink”
-This was important because the stench was so bad that the government had been shut down. Soaking the curtains with Chloride did not work. Sanitation development was important to society because before when diseases such as Cholera emerged, thousands of people passed away due to unsanitary conditions. This is important because humans produce 13 gallons of feces per year which 10% of it is bacteria. An example is from Medieval Europe which people abandoned sanitation practices and threw their poop outside of their house that were later polluted in waterway, which did not separate drinking water from waste water.
o 1855: Parliament passed anti-stinky-fumes Bill
o 1897: outbreak in Hamburg
o 1911: last documented US outbreak
