He began building the present Manor House in 1807 while still operating the iron mines and forges on the property. For the next half century, Ryerson ran five forge-furnace complexes in three counties from his headquarters at Ringwood. He made shot for the War of 1812. The Ryerson Steel Company is still operating today. In 1854, Peter Cooper, an inventor and industrialist from New York purchased Ringwood Manor. One of the Manor's last owners was Cooper's son-in-law, Abram S. Hewitt, ironmaster, educator, lawyer, U.S. Congressman, and mayor of New York City.Original file name Collage_Fotor-1.jpg3600x2700Each photograph within this collection is protected by copyright and/or related rights.
