The Incident of the Broad Street Pump

John Snow by Derringdos

For last year’s term paper, I wrote about John Snow and how he discovered how cholera was spread through water during the Soho cholera outbreak of 1854. John Snow was the first person to disprove the miasma theory (the idea that disease is spread through bad air), though Pasteur is often wrongly credited with this discovery. During our trip to London this summer we visited a replica of the Broad Street Pump, which helped Snow in finding the cause of the disease. There is a nearby pub named after John Snow, and nearby is the former site of his house. It was so exciting to walk around in the neighborhood where Snow made his incredible discovery!
