As the United States industrialized in the early 18th century, Newark grew to become one of the leading industrial centers of the country. Newark’s main areas of manufacture were leather, beer and precious metals. However, many other kinds of goods were produced in workshops and factories throughout the city. For example, Franklin Murphy, one of the Newark Museum’s founding trustees, was a varnish manufacturer. Everything from carriages, automobiles, furniture, pearl buttons, silk stockings, tools and machinery was produced here as well. Tiffany & Co. opened an enormous factory in Newark’s North Ward, in 1894, and by 1929 it and other Newark workshops were producing 90 percent of the gold jewelry made in America.
