Nobody. It was John Snow in 1854
Do you mean the "Broad Street Pump" (19th century cholera outbreak in London)?
Cholera bacteria was first isolated by Filipo pancini 1812-1883, 84 years before he was actually credited with its discovery. A paper was published by him in in 1854 during the Asiatic cholera pandemic of 1846-63. in it he has the description of the cholera causing organism and its relationship to the disease. It was titled Microscopical observations and pathological deductions on cholera.
Name of the physician was Dr John Snow. The cholera out break occurred near Broad street in Soho district of London. (Now renamed Broad-wick street.)
In 1854, Dr. John Snow created a detailed map of London plotting the locations of cholera cases and public water pumps. By visually correlating the outbreak's spread with the water sources, he identified a specific pump on Broad Street as the epidemic's source. This mapping approach not only highlighted the link between contaminated water and cholera but also led to the removal of the pump handle, significantly reducing the outbreak and demonstrating the importance of epidemiology in public health.
these institutions had their own wells and the brewery employees and workhouse inhabitants did not use water from the affected well.
he stopped it by tracking down loads of people in1854 and found they all drank from a well john snow soon tracked down the well and with the evidence he had he shut the well down and cholera had gone he had saved the day
In 1854 John Snow mapped the cases of cholera in Soho, London, and realised that almost all of them were likely to have taken their water from the same pump. The spread of cholera stopped when the handle of the Broad Street pump was removed.
