Storyboard Text

  • Care for a cup of tea fine sir?
  • We quit!
  • Their once lived an ordinary man named John Snow who became a doctor in the year 1844 and was born from a wealthy family.
  • His first piece of scientific work was on the use of Arsenic in the preservation of bodies (this work was abandoned due to the toxic effects on the medical students)
  • From his studies in toxicology, John Snow developed an interest in anaesthesia and cholera (hence his theory on the transmission of the cholera 'poison' in water supplies)
  • In August 1854, a cholera outbreak occurred in Soho. After careful investigation, including plotting cases of cholera on a map of the area, Snow was able to identify a water pump in Broad (now Broadwick) Street as the source of the disease.
  • On 7 September 1854, Snow took his research to the town officials and convinced them to take the handle off the pump, making it impossible to draw water. The officials were reluctant to believe him, but took the handle off as a trial only to find the outbreak of cholera stopped.
  • The cholera outbreak was stopped and John snow was praised as a hero of public health
