Originally known as the Bloomingdale section of Pequannock Township in Morris County, Butler was starting to become a well settled community shortly following the end of the Civil War. Like other small communities in this section of Morris County, the early industries relied upon a source of flowing water to provide power for mills and other manufacturing facilities. In the case of Butler, the Pequannock River provided the needed source of waterpower. The products not sold locally from these mills and factories had to be shipped to larger markets in Paterson or Newark by horse drawn wagons. These conditions dramatically changed when the railroad finally was brought into the community.
