Salem County is exceptional in New Jersey and the United States for being an agriculture epicenter and, at the same time, an industrial hub. During its early history, farms spurred the growth of Salem County towns, including Elsinboro, Pilesgrove and Oldman's Township. Then and now, tomatoes were a popular product of this south New Jersey region. Salem County residents were always industrious, and mills and glass manufactories sprang up as well. The region's landscape and culture were later revolutionized with the arrival of DuPont in the late nineteenth century. Local historian Charles Harrison chronicles these events, along with the rest of the unusual and rich history of Salem County, New Jersey.
