Settled in the 17th century, the village known as Franklin Furnace after Benjamin Franklin, developed near iron mines and iron smelting operations located along the Wallkill River. In the early 19th century, zinc deposits in the area began to be developed commercially. For most of the century many small companies mined zinc and iron in the Franklin area. In 1897 all zinc mining efforts merged into the New Jersey Zinc Company, which was a major controlling factor in the development of Franklin. Immigrants from Russia, Britain, Hungary and Poland joined the work force at the mine. The population, 500 in 1897, had swelled to 3,000 by 1913. On March 18, 1913, the Borough of Franklin was incorporated from portions of Hardyston Township, based on the results of a referendum held on April 23, 1913.
