Prior to that, the area was known as Bloomingdale throughout the 19th century and was initially a farming community starting about 1712 with the "Bloomingdale Forge" built shortly thereafter to take advantage of the iron in the hills. The business district along the Paterson-Hamburg Turnpike and the Pequannock River began about the middle of the 19th century.
