Mapping Historical New Your - Phase II: Columbia University has been awarded a major grant from the Robert David Lion Gardiner Foundation to create an online, interactive atlas of historic New York City spanning the years 1820 to 1940. The project is a collaboration of Columbia’s History Department and the Center for Spatial Research in the Graduate School of Architecture, Planning and Preservation (GSAPP). The new atlas will be a continuation of work made possible by the Robert David Lion Gardiner Foundation’s $1 million grant in 2017 to map the Manhattan and Brooklyn of the late 19th and early 20th centuries. The next phase, driven by the new grant of $922,000, will add Queens, the Bronx, Staten Island, as well as Nassau and Suffolk counties.
