Princeton, New Jersey is a community located in Mercer County, New Jersey, United States. Princeton University has been sited in the community since 1756. Although Princeton is a "college town", there are other important institutions in the area, including the Institute for Advanced Study, Educational Testing Service (ETS), Opinion Research Corporation, Siemens Corporate Research, Bristol-Myers Squibb, Sarnoff Corporation, FMC Corporation, The Robert Wood Johnson Foundation, Amrep, Church and Dwight, Berlitz International, and Dow Jones & Company.
The community is roughly equidistant from New York and Philadelphia. Princeton has been connected to New York and Philadelphia (via Princeton Junction) since the nineteenth century. The community is close to many major highways that can take residents to both cities. While the Amtrak ride time is similar to each city, the commuter train ride to New York — via New Jersey Transit's Northeast Corridor Line — is generally much shorter than the equivalent train ride to Philadelphia, which involves a transfer to SEPTA trains in Trenton. Princeton receives some TV and radio broadcasts from both cities.
New Jersey's capital is the city of Trenton, but the governor's official residence has been in Princeton since 1945, when Morven in the borough became the first Governor's mansion. It was later replaced by the larger Drumthwacket, a colonial mansion located in the township. Morven became a museum property of the New Jersey Historical Society.
