The Hudson area was once heavily wooded, but it quickly grew to be a suburban-type community for middle-class families. This area became popular with Irish railroad laborers and German merchants. Hudson is also home to the Hudson City Saving Bank, which was chartered by the New Jersey Legislature in 1868. The first president of the bank was Garret D. Van Reipen, who served as its second mayor.
After the Great Depression, Hudson became a booming industrial center. In addition to manufacturing and shipping goods, Hudson was also a center for prostitution and gambling. This activity helped Hudson's reputation as a "big red light district."
