The Ghost Map: The Story of London's Most Terrifying Epidemic—and How It Changed Science, Cities, and the Modern World by Steven Johnson

5.0

It's mind boggling how long europeans still believed in the miasma theory. It's pretty embarrassing. I knew about Snow and discovering the water-cholera connection but this gave a lot of fascinating details about how folks still fought with him because they weren't convinced (despite his excellent science work for the time) that it was the water and not miasma. I think this is an important book for people interested in the history of science and medicine, as well as urban planning (I have a degree in it and we discussed this a bit in college) and history in general.
