In “ Ghost Map”, Steven Johnson tells the story of the terrifying cholera epidemic that engulfed London in 1854, & the two unlikely heroes
- anaesthetist Doctor John Snow & affable clergyman Reverend Henry Whitehead
- who defeated the disease through a combination of local knowledge, scientific research & map-making. In telling their extraordinary story, Johnson also explores a whole world of ideas & connections, from urban terror to microbes, ecosystems to the Great Stink, cultural phenomena to street life. Re-creating a London full of dirt, dust heaps, slaughterhouses & scavengers, “ Ghost Map” is about how huge populations live together, how cities can kill
- & how they can save us.
