Robert Judge Livingston was a very influential figure in the history of the Revolutionary War, even serving as a delegate to the Stamp Act Congress (or Continental Congress) of 1765. He married Margaret Beekman, who also heralded from a prominent family, and they had a son named Robert R. Livingston, who became known as The Chancellor because he was New York's first chancellor. In October of 1777, in the midst of the Revolutionary War, a small force of British soldiers arrived and burned down the estate as well as 24 other buildings on the property in response to the Livingston's support for independence. Margaret Beekman Livingston managed to escape with her daughters and son Robert R. Livingston to a relative's home in Connecticut. After the war, Margaret sent numerous letters to the governor of New York and secured enough militia exemptions for Clermont to be rebuilt.
In addition to being the highest judge in New York State, Robert R. Livingston The Chancellor served on the Committee of Five that drafted the Declaration of Independence, and he went on to draft the State of New York's Constitution. His illustrious career did not end after the Revolutionary War; he administered the oath of office to George Washington in 1789, served as the first Secretary for Foreign Affairs, and was the chief negotiator for the Louisiana Purchase with Napoleon Bonaparte. Also a brilliant inventor, The Chancellor was a co-inventor of the first commercially used steam boat.
Clermont remained in the family and the final Livingstons to reside at Clermont were John Henry and his wife Alice. In 1909, their other home, the historic Arryl House, burned to the ground. Visitors are still able to see the ruins of Arryl House at the south end of the parking lot at Clermont. Alice was respectful of Clermont's rich history and she created the beautiful gardens that are still apart of the property. In 1962, a widowed Alice turned Clermont, which still appeared as it did in the 1930s, over to the State of New York.
