The island was long inhabited by
indigenous peoples, related to those who lived north of Long Island Sound. At the time of European encounter, it was occupied by the
Manhanset tribe, an
Algonquian-speaking people related to the
Pequot and other Algonquians of New England. The original name of the island, used by the Manhanset Indians, is Manhansack-aha-quash-awamock, which literally translates to "Island sheltered by islands."
Early settlers Shelter Island was included in the original
Plymouth Company land grant made by
James I of England in 1620. On April 22, 1636,
Charles I of England, told that the colony had not made any settlements yet on Long Island, gave the island to
William Alexander, 1st Earl of Stirling. The grant gave Alexander all of Long Island and adjacent islands. Alexander gave James Farret power to act as his agent and attorney in colonizing Long Island. In reward Farret was allowed to choose for his personal use. Farret chose Shelter Island and
Robin's Island for his use. Farret in turn sold the islands to Stephen Goodyear, one of the founders of the
New Haven Colony. In 1651 Goodyear sold the island to a group of
Barbados sugar merchants for 1,600 pounds of sugar.
Nathaniel Sylvester (1610–1680), one of the merchants, was the island’s first white settler. By that time the Manhansett had declined in number and power. In 1652 Sylvester constructed a house on the island for his 17-year-old bride, Grissel (also spelled Grizzel) He was the first town supervisor on the island. His former home is now owned by the local historical society.
Jonathan Nicoll Havens (1757–1799), born on Shelter Island, was a member of the
First Continental Congress in 1774. He also served in New York’s delegation that in 1788 approved the federal constitution. Mashomack Forest (today Mashomack Nature Preserve) was owned by the Nicolls family for 230 years. Nicolls Creek was named for that family. A few Manhanset still lived in the wooded
Sachem’s Neck area up until the 1790s. Shelter Island had brushes with early Colonial military activity: • The British shipped hay from Hay Beach during the
American Revolution. • The schooner
Paragon was built on the island at Lord’s Shipyard, located on West Neck Creek. In 1804 the ship under Capt. Sam Lord successfully ran a British blockade during the
Napoleonic Wars. • During the
War of 1812, the British ransacked numerous homes on the island. The first ferryboat to serve the island was run by the Boisseau family at Stearns Point, nearby Crescent Beach. The
North Ferry began service to
Greenport in the 1850s. Throughout the 19th century, the island continued as a base for fishermen in the surrounding waters. Fish processing plants sent their products across the country.
Shelter Island Heights established Shelter Island Heights was developed in 1871 as a summer resort for
camp meetings, after a group of
Brooklyn businessmen purchased the
Frederick Chase estate for this purpose. It was developed by the Shelter Island Grove and Camp Meeting Association of the
Methodist Episcopal Church. For eight years, the camp meetings took place on the island, before moving to
Jamesport. During this time,
Robert Morris Copeland designed the Union Chapel, built in 1875. In 1984 it was added to the
National Register of Historic Places (NRHP). Shelter Island Heights in total was a planned development by Copeland. The houses were designed in classic American styles:
Stick-Eastlake,
Queen Anne Style, and
Colonial Revival. During the eight years from 1872 to 1880, when camp meetings were held here, about 70 summer cottages were built in the Heights. By 1890 the district was well-defined architecturally; the residences have not changed much since then. Shelter Island Heights was listed in 1993 as an Historical District on both the NRHP and the New York State Register of Historic Places. At the turn of the 20th century, fish processing plants still operated on the island. One was located at the end of Burns Road, another on
Big Ram Island, off what is today Tuthill Road. Some summer residents traveled here by steam ferries from New York City. White Hill is located above the North Ferry landing in Shelter Island Heights. The Prospect Hotel was built on the hill. After it burned down, it was rebuilt, but was destroyed a second time by fire in 1942. Today the land where the hotel was located is a town park.
Growth after 1900 Francis Marion Smith (1846–1931) was known as the "
Borax King" for his mining successes. Smith and his family bought a home on the island in 1892. He expanded it to more than 30 rooms and called his estate
Presdeleau (French for "by the water"). By 1906 he owned more than on the south side of the island. Smith Cove and Smith Street were named for him. Smith shipped in deer from California to hunt in his "deer park"; their descendants roam some areas of the island. The remains of his estate are reinforced concrete retaining walls and a "Japanese"
footbridge from the garden, built by
Ernest L. Ransome about 1898, behind Merkle Lane. Another 19th-century millionaire who had an estate on Shelter Island was
Artemas Ward (1848–1925), a pioneer in mass-market advertising. Ward made millions of dollars by monopolizing all advertising on New York City elevated trains,
subways, and streetcars. Ward had a large estate on the south side of the island. Ward wrote a biography of his great-grandfather, Major General
Artemas Ward (1727–1800), a commander in the
American Revolutionary War. After years of being tied up in court, the vestiges of Ward’s original estate in the Shorewood section of the Island (including a manor house, formal Italian gardens, and a concrete water tower) have been renovated. In the case of the manor house, it has been partially "deconstructed" to restore an earlier version. Following
World War I, development slowly crept onto the island. Summer camps were started in the 1920s, including Camp Quinipet, a
United Methodist Church camp and retreat center on Rocky Point Road. On West Neck Harbor, developers Albert and Fred Dickerson built houses for what is today called Montclair Colony. Homes were built on Silver Beach, Ram Island, and Hilo Farms. Following the
Depression, some of the summer cottages were abandoned or left to rot. Recovery was slow. It was not until after
World War II that summer residents started returning in larger numbers. During the 1950s a farm cooperative grew lima beans on the island. This was the last of commercial farming on Shelter Island. In the 1960s and 1970s, more families started to move to Shelter Island as year-round residents. The Gerard family owned the property at Sachem’s Neck that had belonged to the Nicoll family for more than 200 years, and later to financier
Otto Kahn. Developers eyed the . The land was purchased in January 1980 by the
Nature Conservancy to preserve it as a nature park in perpetuity; half of the funds to buy the forest were raised on the island to create Mashomack Preserve. There are still numerous Shelter Island residents with family roots dating to families here at the time of the
American Revolution. Some summer residents are fifth-generation seasonal visitors. ==Geography==
