Alophus Philipse (1665–1750) was a wealthy landowner of Dutch descent in the Province of New York.
Alophus Philipse was born in 1665, the second son of Frederick Philipse, the first Lord of the Manor of Philipsborough, a Dutch immigrant to North America of Bohemian heritage who had risen to become one of the greatest landholders in the New Netherlands.
In 1697, Philipse purchased a tract of land which ran along the northern Westchester County border, which received Royal sanction as the "Highland Patent". Spanning from the Hudson River to the then Connecticut Colony it encompassed some 250 square miles.
Upon Frederick's death in 1702, Adolphus received all the Manor north of Dobb's Ferry, including the present town. He was also named proprietor of a tract of land on the west bank of the Hudson north of Anthony's Nose and executor of Philip's estate. The balance of the Manor, the hereditary title, and family commercial holdings were bequeathed to his nephew, Frederick Philipse II.
After the bachelor Adolphus' death in 1749 (Smith, others 1750), his Manor holdings and the Highland Patent passed to Frederick II, his only heir-at-law, who became the second Lord of the Manor at Philipsborough.
During the American Revolution the Patent lands, in time known as the "Philipse Patent", were confiscated by the Provisional New York government's Commissioners of Forfeiture. Sold afterwards, they became today's Putnam County.
In 1697 Philipse purchased a tract of land from Dutch traders Lambert Dortlandt and Jan Sybrandt, who had bought it a few years before from several Wiccopee chiefs. This became known as the Highland Patent, and extended approximately 13 miles along the east shore of the Hudson River, from Annsville Creek to the Fish Kill, and eastward some 20 or so miles to the border of the Colony of Connecticut, including Pollopel Island in the Hudson.
Shortly after purchasing it, Philipse, whose residence was the Philipse Manor Hall near Tarrytown, and who maintained only a bachelor shooting lodge on Lake Mahopac in the Highland Patent, opened the tract to tenant settlers. Thus began a policy that lasted throughout his lifetime and his heirs' so long as they owned the land, to rent rather than sell, a practice which led to stunted growth for two and a half centuries to come.
After Philipse's death in 1750 (Smith, 1749), the Highland Patent was inherited by his nephew, Frederick Philipse II, his only heir-at-law, who became the second Lord of the Manor at Philipsborough in Westchester County.
Adolphus Philipse was the second son of Frederick Philipse, the first Lord of the Manor of Philipsborough, and Margareta Hardenbroeck. He was the younger brother of Philip Philipse, Annetje Philipse, Adolph Phillipse, Anna Philipse, Rombout Philipse, Frederick Phillipse, Charles Phillips, Hendrick Phillips, Catherine Phillips, and William Phillips; and half brother of Eva Maria Phillips de Vries.

To confirm his title to this additional tract Adolph Philipse obtained a new Indian deed in 1702."

Sparkes, Esq., governor of Barbadoes, by Joyce, his wife, daughter of ? Farmer, Esq., (two of whom had retumed to their father's estate in Worcestershire, and the others accompanied their parents to the island), and, dying in 1700, left a son and successor. She also died in 1700.
- Glenn, p. 258: "By the will of Frederick Philipse "all that portion of the manor north of Dobb's Ferry, including the present town, became vested in Adolphus Philipse, his second son. This individual " was also proprietor" of a great tract of land north of " Anthony's Nose " and the executor of his brother Philip Philipse's estate, the latter having died in 1714. Adolphus died without issue in 1750, and the whole manor of Philipsborough descended to his nephew, Frederick Philipse, the nearest male heir of the grandfather. This nephew was born in 1698 upon the island of Barbadoes, at an estate called Springhead belonging to his father."

- Philipse family history: At the death of Frederick Philipse in 1751, the Highland Patent was inherited by his son, Philip Philipse, and three daughters, Susannah (wife of Beverley Robinson), Mary (late wife of Col. Roger Morris), and Margaret, who died intestate. Margaret's portion was, by terms of her father's will, equally divided among her brother and sisters, and in 1751, after a survey of the whole tract, it was geographically divided into nine Lots; three on the river; three in the interior; three on the eastern (Connecticut) border. Each of the three heirs inherited a lot in each division.
