Cooper-Hewitt Papers received from the Passaic County Historical Society

Box 17: Trenton Iron Company, New Jersey Iron & Steel Company, American Bridge Company, Brooklyn Bridge, and Standard Oil

Historical Explanation: Cooper, Hewitt & Company, originally located at No. 17, Burling Slip, New York City, were proprietors of New Jersey Steel and Iron Works and The Trenton Iron Works (both having offices in Trenton, NJ).  They produced and sold rolled iron beams, railroad iron, railroad axles, locomotive tires, refined bar iron, steel-headed rails, charcoal pig iron, brazier's and wire rods, and other iron items.  After Peter Cooper moved his new iron company out from the city, to New Jersey due to noise and smoke complaints by neighbors, he renamed it as the South Trenton Iron Company. When Peter Cooper's son Edward Cooper and Abram S. Hewitt joined in a professional partnership, they created Cooper & Hewitt, created to act as a managing firm for the Trenton Iron Company, and to hold half of the stock first issued.  Peter Cooper remained President of the Trenton Iron Company, owning approximately the second half of the stock.  In 1860, Peter Cooper resigned as president of the Trenton Iron Company, and turned over all responsibility except the most important financial matters to Abram Hewitt and Edward Cooper. (p. 206-207, Peter Cooper, by Edward C. Mack).  In 1886, due to competition with the new western giants, Cooper & Hewitt bought the rolling mills from The Trenton Company, and set up a separate corporation to roll iron and steel called The New Jersey Steel & Iron Company (p. 216, Peter Cooper by Edward C. Mack).
