Event Details


Billboards, Boats, and Barter on the Bay

A Year of the Bay Hackathon 

Exploring the Waterfront Businesses of SF


Travel back in time along the old Embarcadero, as we zoom in on an amazing collection of photographs from the waterfront of San Francisco and solve some historical photo mysteries. Dig through old city directories and maps to find more about the businesses of old San Francisco.

Join hackers, historians, curators, and history geeks in exploring and documenting rarely seen photographs from the California Historical Society, the San Francisco Public Library, the San Francisco Municipal Transit Authority Archives, and the San Francisco Maritime National Historic Park.

What is a hackathon? It’s when a bunch of people get together to use a variety of tools (often technological ones) to solve problems. In this case, we’re looking at building better historical information and resources for apps that aid in the discovery of historical data. 


This event is part of the Year of the Bay project, a year-long series of online and offline events to help gather the diverse history of the San Francisco Bay. 

Special thanks to our cultural heritage partners mentioned above, and our event partners: Pastmapper and Historypin.
