Hartsdale is located in the town of Greenburgh, Westchester County, New York, United States. The population was 5,293 at the 2010 census. It is a suburb of New York City.
Hartsdale, a CDP/hamlet/post-office in the town of Greenburgh, New York, lies on the Bronx River 20 miles (32 km) north of New York City. It is served by the Metro-North Harlem River commuter rail line into Grand Central Terminal. Hartsdale is the home of America's first canine pet cemetery (started by veterinarian Samuel Johnson in 1896), and the world's first Carvel Ice Cream store (1934), which closed in 2008.
Hartsdale's earliest settlers were the Wecquaesgeek (sometimes spelled Weckquaesgeek), a sub-tribe of the Algonquian tribe that lived in most of southern New York, from Westchester down through Manhattan. Weekquaeskeek is an Algonquian term believed to mean "place of the bark kettle", and this kettle appears in the Greenburgh town seal.
After the earliest British colonialists arrived, the area was developed under the manor system when Frederick Philipse, a Dutch merchant and British Loyalist, was "given" the land by the British government. As lord of his Philipse Manor, he leased his land to tenant farmers who, at least for a time, were believed to have lived alongside their Native American neighbors.
There is evidence to show that Hartsdale played a significant role during the Revolutionary War, some of which still stands today.
