Hamilton Fish (b. 1808 New York, NY, d. 1893 Philipstown, NY) served as the Governor of New York, a US Senator, and US Secretary of State.
In 1861 Hamilton Fish bought a large plot of land in nearby Garrison and constructed a large estate at a cost of $30,000 for himself and his family. The home, which he named "Glenclyffe", had 5 bedrooms, 6 bathrooms, 3 servant's rooms, a library, drawing room, dining room, billiard room, den, morning room and a boudoir. The property near Arden Point (down river), had a large green house, stables, expansive gardens, gate house and spectacular views of the Hudson. Today, the home and property belong to the Open Space Institute. Thanks to wikipedia for the details.
And in case you were wondering, Hamilton Fish was named after his parents’ friend, Alexander Hamilton. Info from Wikipedia.
