History of San Francisco Place Names by Noah Veltman

This interactive map teaches you the history of street and landmark names in San Francisco. I started the project because these names turn out to be a wonderful window into different layers of local history, and we encounter them every day (on every street corner, even) but rarely stop to think about where they come from.
You can browse the map, choose from a list, search by name, jump to a neighborhood, filter by themes (like "Gold Rush," or "Politicians"). If you're in the city on a mobile device, you can also get the history of places near your current location.
