• Cholera 1849: low ground, bad water and a long shadow

  

  In 1849 cholera killed 14,007 people in London. I rebuilt William Farr’s elevation law and John Snow’s water evidence from their own tables, mapped every death around the Broad Street pump, and found that the worst-hit districts of 1849 are not the poorest today.
