Cold Spring Harbor was named after the naturally cold freshwater springs that flow in the area. Its economy mainly tied to milling and port activities, it rose in prominence as a whaling community in the mid-nineteenth century. After the decline of whaling in the 1860s, it became a resort town with several hotels. In the 20th century it became known as the site of Cold Spring Harbor Laboratory, although the laboratory itself is located in the adjacent village of Laurel HollowinNassau County, which was called Cold Spring before incorporation.
Today it is primarily a bedroom communityofNew York City, with a small central business area running along Route 25A, and is home to many educational and cultural organizations: the Cold Spring Harbor Whaling Museum, the Cold Spring Harbor Fish Hatchery and Aquarium (also in Laurel Hollow), Dolan DNA Learning Center, the Uplands Farm Sanctuary (home of The Nature Conservancy's Long Island chapter), and a museum exhibition gallery run by Preservation Long Island.
