In 1854, at the height of a new cholera epidemic in the Soho district around Broad Street, John Snow, a physician, plotted the course of the cholera outbreak on a map he drew himself and worked out from the map that all the victims had used the same Broad Street water pump. As an experiment, Snow removed the handle from the pump so no one else could drink from it and from then onwards no one else in the area became infected. Snow had stopped the spread by removing the source of the disease – the water pump. He discovered the connection between contaminated water and cholera.
