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



The Ghost Map: The Story of London's Most Terrifying Epidemic – and How it Changed Science, Cities and the Modern World by Steven Berlin is an utterly absorbing book which details the cholera outbreak in London’s Soho district in 1854.

The book follows the investigations of Dr. John Snow, a local physician and the local Soho Anglican priest, Henry Whitehead. Together they provided convincing evidence that the outbreak of cholera was due to contamination of the Broad Street water pump and ushered in the modern science of epidemiology.

The book has many merits.  Berlin understands that the discovery of the cause of the epidemic was a crossroad in medicine, urban planning, demographic studies, municipal and public policy. The outbreak and the discovery of its source made large scale urban living, without massive outbreaks of deadly disease, possible. 

So although the title contains the hyperbole of so many recent non-fiction books, the case examined here really does deserve credit for ushering in the modern field of health care and its related policies and the most salient feature of modern living - mega cities.
