Kemble was born in 1786 to a prominent family in New York City, the eldest son of prosperous attorney and merchant Peter Kemble of New Jersey. Ships of the firm Gouverneur & Kemble conducted trade in the West Indies, Europe and China. Kemble was educated in New York and graduated from Columbia College in 1803, then entered the mercantile business. He was friends with Washington Irving and other members of city society, who enjoyed socializing at Cockloft Hall. He was a founding member of the "Lads of Kilkenny". His sister, Gertrude, married James Kirke Paulding in November, 1818. Through his grandmother Gertrude Bayard, Kemble descended both from the Schuyler family and the Van Cortlandt family.
Diplomat
Kemble was sent to the Mediterranean as a naval agent during the Second Barbary War with Tripoli. As a young man with political connections, in 1816 he was appointed United States Consul at Cádiz in Spain, where his attention was attracted to the Spanish government's state-of-the-art process of casting cannon.
Manufacturer
Returning home, Kemble saw an opportunity to introduce the process in the United States. Along with other partners including his brother William and a consortium of investors including General Joseph Gardner Swift of the U.S. Army, around 1817 he founded the West Point Foundry Association to produce artillery pieces for the United States Government. The need of such an establishment was demonstrated by the War of 1812. The foundry was built across the Hudson River from West Point in the village of Cold Spring, New York, and soon began to make cast iron steam engines for locomotives, gears, water pipes, and other iron products, as well as artillery. Despite the lack of local artisans and craftsmen skilled in ironworking, Kemble and his partners succeeded, especially after they hired William Young, a native of Belfast, Ireland. Robert P. Parrott became superintendent in 1836 and the Foundry weathered the Panic of 1837. Kemble continued to be president of the association until the expiration of the charter. He became known as the "Patriarch of Cold Spring" for his charitable activities in the village. In 1823, Gouverneur Kemble leased land in Orange County, New York, for the mineral rights to mine iron ore. Four years later, the Kembles acquired most of the nearby Greenwood Iron Foundry and related industries. In 1839, the brothers sold the foundry to Parrott. A year later, his sister Mary married Parrott.
Gouverneur Kemble died in Cold Spring on September 16, 1875, at the age of 89 and was buried in Cold Spring Cemetery. An 1853 oil portrait of Gouverneur Kemble by Asher Brown Durand is in the National Gallery of Art in Washington, D.C. Famed Civil War general Gouverneur Kemble Warren, born in Cold Spring in 1830, was named for Kemble, a close friend of his father, Sylvanus Warren.
