Another miasmic theory believer during this time

Another miasmic theory believer during this time period was William Farr. Farr agreed with Snow in that the water had something to do with the cholera outbreak. Where Snow believed it was something that contaminated the water, Farr believed there was a correlation between elevation and the miasma levels in water. Believing this led Farr to conduct an experiment in which he tested water at different elevations and compared these statistics to mortality rates in the area. He came to find that lower parts of the river had stronger miasmas than higher parts and the death rates correlated with this. This new intel is what led Farr to agreeing with Snow’s theory. Lastly, Edwin Chadwick was in a league all of his own. Chadwick was a sanitarian. He believed that simple sanitation methods could get rid of the disease and continued to believe so until he died. He ended up contributing more to the spread of the disease rather than the prevention. Chadwick believed that having trash in the rivers was better than having it in the sewers, so he regularly had the sewers flushed into the Thames River. This led to higher levels of contamination in the Thames which was the source of water for many water companies. The

high contamination levels in the Thames combined with no filtration, aided in the spread of cholera during this time. When looking at the main contributors to the research of cholera, it is clear that Chadwick was completely against everyone else. He was a firm believer in his theory whereas Farr, Snow, and Whitehead seemed to work on the same big picture. Whitehead and Snow worked together best of these men as their research overlapped and at times, was done together as they felt similarly about the spread of disease. Although Farr didn’t directly agree with Snow’s work, he had similar beliefs and some of Snow’s work influenced him as well. Snow seemed to be the biggest contributor to the end of the cholera outbreak. Through his research and publications, this outbreak was eventually able to come to an end.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
