Steven Johnson on TED Talks

Steven Johnson on TED Talks: "Author Steven Johnson takes us on a 10-minute tour of The Ghost Map, telling the story of a cholera outbreak in 1854 London, and the famous map that physician John Snow made of the disease's path - a map that not only convinced the world that cholera was a waterborne illness, but ultimately brought about profound changes in science, cities and modern society."

Cholera visited early Bay City and Michigan. This talk gives an overview of public health in the greatest city on Earth in the 1850's. Bay City was highly affected by these views of public health.
