Who was John Snow and what was his contribution to science?
John Snow (shown below) was a physician in London who spent several decades studying cholera in a systematic way. He is most often credited with solving an outbreak of cholera that occurred in London in 1854 (the outbreak is described below), but his studies of cholera were much more extensive than that.
What was John Snow’s theory?
John Snow was born into a labourer’s family on 15 March 1813 in York and at 14 was apprenticed to a surgeon. However, Snow did not accept this ‘miasma’ (bad air) theory, arguing that in fact entered the body through the mouth. He published his ideas in an essay ‘On the Mode of Communication of Cholera’ in 1849.

How did John Snow diagnose and treat cholera?
Snow was able to prove that the cholera was not a problem in Soho except among people who were in the habit of drinking water from the Broad Street pump. He also studied samples of water from the pump and found white flecks floating in it, which he believed were the source of contamination.
What did John Snow’s cholera map achieve?
Snow collected data and recorded it on his map so he could determine where the greatest number of cholera cases and deaths occurred. This was a laborious process for Snow, but GIS provides tools that help us answer this question quickly.
Why is John Snow so important?
But it was not until 1854 that the physician John Snow (1813-1858) made a major contribution to fighting cholera when he was able to demonstrate a link between cholera and the contaminated drinking water through his pioneering studies.
What was the purpose of John Snow’s research?
In epidemiology, Snow investigated the relationship of water supplies to mortality in cholera during the London epidemic in 1854, which led him to formulate an original and valid theory of the transmission of cholera.
How did John Snow present his findings?
In August 1849 Snow published a paper entitled “On the Mode of Communication of Cholera” in which he presented his theory that the disease was acquired by ingestion of contaminated water, but his theory did not get much traction with the medical establishment.
