TECH TALK: Good Books: The Ghost Map

June 21st, 2007 · No Comments

Steven Johnson’s book Emergence was one of the inspirations for this blog’s title. His newest book is The Ghost Map. It is about the 1854 cholera epidemic in London. This is what Publisher’s Weekly wrote: In August 28, 1854, working-class Londoner Sarah Lewis tossed a bucket of soiled water into the cesspool of her squalid apartment building and triggered the deadliest outbreak of cholera in the city’s history. In this tightly written page-turner, Johnson uses his considerable skill to craft a story of suffering, perseverance and redemption that echoes to the present day. Describing a city and culture experiencing explosive growth, with its attendant promise and difficulty, Johnson builds the story around physician John Snow. In the face of a horrifying epidemic, Snow (pioneering developer of surgical anesthesia) posited the then radical theory that cholera was spread through contaminated water rather than through miasma, or smells in the air. Against considerable resistance from the medical and bureaucratic establishment, Snow persisted and, with hard work and groundbreaking research, helped to bring about a fundamental change in our understanding of disease and its spread. Johnson weaves in overlapping ideas about the growth of civilization, the organization of cities, and evolution to thrilling effect. From Snow’s discovery of patient zero to Johnson’s compelling argument for and celebration of cities, this makes for an illuminating and satisfying read.

Here is what Steven Johnson wrote after finishing the first draft of the book:

This book has a single, sustained narrative line running through it, a first for me. It’s the story of the Broad Street cholera outbreak that took place in London in September of 1854. The outbreak itself was arguably the deadliest in London’s history — it literally decimated the western side of Soho, killing more than ten percent of the population there in a matter of eight days — but it is most famous for the map that the physician and epidemiologist John Snow made of the outbreak, a map that eventually helped convince the world that cholera was in fact a waterborne illness, and not transmitted via the air as the then-dominant miasma theory maintained.

In many ways, the story of Broad Street is all about the triumph of a certain kind of urbanism in the face of great adversity, the power of dense cities to create solutions to problems that they themselves have brought about. So many of the issues that define the modern world today — the runaway growth of megacities, environmental crises, fears of apocalyptic epidemics, digital mapping, the need for clean water, urban terror, the rise of amateur expertise — are there, in embryo, in the Broad Street outbreak.

So The Ghost Map is in part a disease thriller, with some genuinely spooky and unsettling narrative turns. But it also widens its focus to tell the history of London’s sewer system, the evolutionary history of bacteria, the biological and cultural roots of the miasma theory, the bizarre waste management techniques of Victorian society, and so on. It is the story of ten days in London in 1854, but it’s also an attempt to tell that story at three different scales of experience: from the point of view of the humans living through it, but also from the point of view of the cholera itself, and the city.
