Atlantic City is located in the northeastern part of the state of New Jersey and is considered to be a resort city in Atlantic County, that sits nearby the Atlantic Ocean. The city is situated in a narrow, sandy, and low Absecon Island, wherein it was separated from its mainland by a narrow strait and a number of miles of meadows that are covered partly with water during high tide. The area was inhabited by the Delaware Indians, even before the arrival of the English settlers who arrived in around late of the 1670s. The island was envisioned to be developed as a summer resort by the physician Jonathan Pitney, who arrived in the community and wanted to establish a health resort around 1820. He then became a leader of a group that then persuaded the Camden and Atlantic Railroad to make the area its terminus on the eastern side. The success spurred the construction of another railroad line in 1877, the Narrow Gauge Railroad.
