John Snow: a historical giant in epidemiology

John Snow: a historical giant in epidemiologyA comprehensive, rich-media site devoted to John Snow, the 19th century epidemiologist known for using a map of London to graphically portrait the pattern of deaths caused by a cholera outbreak. This data supported his theory that the disease spread via water (a theory that was by no means widely accepted by the medical community at the time). He removed the handle of a pump that his map pointed to as the source of contaminated water. The outbreak abated. More recent readings of the events suggest that the outbreak was on the wane anyway. There are many nicely presented graphics and a thoughtful user interface on this site which was created and designed by Ralph R. Frerichs of UCLA's Department of Epidemiology.
