This is going on my Amazon wish list to order as soon as it’s in print. John Snow made the first map of a disease’s victims when cholera broke out in and around Broad Street in London in 1854. In making the map he introduced the world to epidemiology, and saved hundred of Londoners from cholera by having the Broad Street water pump closed. He was also first to prove that cholera was spread by germs, and was not the result of a “miasma” as had been thought previously. Snow’s map itself is a masterpiece of information design lauded not just by Steven Johnson in the aforementioned book, but also Edward Tufte. Can’t wait for this. ~
