The Ghost Map by Steven Johnson

The Ghost Map : The Story of London’s Most Terrifying Epidemic–and How It Changed Science, Cities, and the Modern World

by Steven Johnson

Compare a bacteria with a human, with a city, with the planet. Weave in two personal stories and the clash of ideas and of the inherent messiness of progress, and you may get the outline of this book. The Ghost Map is at once a real map, but also a metaphor for progress, for navigation of the future using the past.

The scale at which this book is written jumps all the time and could have collapsed in on itself because it constantly pans and zooms through its subject matter, yet it always stays focused and gripping. The book’s main story are the events around an outbreak of Cholera in London in 1854 around Broad Street, Soho. Two very different people, John Snow and Henry Whitehead, became entangled in the outbreak and eventually through their efforts the battle against Cholera was won, mega cities became possible and the foundations for modern epidemiology were laid.
