At CartoDB we obviously love maps and nobody that really loves map can't tell you the story of John Snow. If you haven't heard of him, we highly recomment reading a bit about his story and how he changed maps and science. In a nutshell, he helped map an 1800s cholera outbreak that took place in London. By mapping the outbreak, he was able to identify a water pump that was the source of the bacteria causing the outbreak.
