History Prior to European settlement, what is now Allamuchy Township was inhabited for centuries by the Lenape Native Americans, until they were forced west by 1742.Helen R. Johnson, History of Allamuchy Township, N.J. (Allamuchy, NJ: Allamuchy Historical Society, 1973), p. 4.

Quaker settlement Acting as a surveyor, John Reading laid out a tract of land for William Penn in 1715 that became the Quaker Settlement, the first non-Native Americans to live in Allamuchy.Johnson, History of Allamuchy (1973), p. 4. By 1752, the Society of Friends, or Quakers, established a community in the northeast corner of what is now Allamuchy Township.Johnson, History of Allamuchy (1973), p. 5. The settlement was chartered in Kingwood, NJ, and the first Quakers to arrive in Allamuchy brought with them the materials to build their homes.Snell, James P., History of Warren and Sussex Counties, New Jersey (Philadelphia: Everts & Peck, 1881), p. 743. The land controlled by the Quaker Settlement spanned an area not just in Allamuchy, but what is now considered Green Township, NJ as well.Snell, History of Warren and Sussex (1881), p. 744. This settlement was known as the "Hardwick Friends," because what is now Allamuchy Township was then a part of Hardwick Township.
In 1735, Quakers selected a plot of land for use as a burying ground with accompanying stone wall and first constructed a wood meeting house in 1752, replacing it in 1764 with a stone building.Johnson, History of Allamuchy (1973), p. 5-6. The Hardwick Meeting sided with a branch of the Society of Friends known as the Hicksites in 1827, an event that compelled many of the Settlement's residents to leave for other Quaker communities. On February 2, 1854, the last Quaker meeting took place in the Settlement; it was formally dissolved in 1855. The Friends' Burying Ground was used until 1918, when its stone wall was repaired and a small monument installed; it was later restored in 1940.Johnson, History of Allamuchy (1973), p. 6-7.
The location of the Quaker meeting house was later used as a public school.Johnson, History of Allamuchy (1973), p. 6. There, in Fall 1921, the Quaker Grove School served as an experimental research station for rural education by researchers Fannie W. Dunn and Maria A. Everett from Teachers College, Columbia University.Johnson, Helen R. History of Allamuchy Township Allamuchy, NJ: Allamuchy Historical Society, 1973, p.11 The result of their fieldwork was the book, Four Years in a County School, which detailed their findings with regards to the single-teacher model, curriculum, and observations about rural education in general.Fannie W. Dunn and Maria A. Everett, Four Years in a Country School (New York: Bureau of Publications, Teachers' College, Columbia University, 1926) In 1940, the Township consolidated its four public schools into a single location, the present-day Allamuchy Township School, and the Quaker Grove school reverted to private ownership.
Grand estates In the late 1700s, John Rutherfurd began construction of his vast home in Allamuchy.Johnson, History of Allamuchy (1973), p. 12. Lewis Morris Rutherfurd later occupied the estate, where he took the first telescopic photographs of the Moon from his home at Tranquility Farms in 1865. His son, Rutherfurd Stuyvesant, raised Holstein cattle, Dorset sheep, English pheasants and hunting dogs on the estate, which included a deer preserve. Under Rutherfurd Stuyvesant, the 47-room house was known as the Stuyvesant Mansion, and was decorated with imported and Duncan Phyfe furniture, Ming Dynasty pottery, and 15th and 16th century suits of armor.Hoff, F. David, and Mrs. Ernest Johnson, "Allamuchy Township," in Historical Sites in Warren County, ed. Richard E. Harpster (Belvidere, NJ: Board of Chosen Freeholders, 1965), p. 6. The Stuyvesant Mansion was last occupied in 1947 and its contents sold in 1951 and 1955.Hoff and Johnson, "Allamuchy Township," in Historical Sites in Warren County, Harpster, ed., (1965), p. 6-7. The Mansion was destroyed by fire in September 1959.Hoff and Johnson, "Allamuchy Township," in Historical Sites in Warren County, Harpster, ed., (1965), p. 7.
Winthrop Rutherfurd commissioned Whitney Warren, architect of Grand Central Terminal, in 1902 to design Rutherfurd Hall. Completed in 1906, the Hall served as a hunting lodge family residence where prominent guests could be entertained, most famously U.S. president Franklin D. Roosevelt who was a close friend of Winthrop's second wife Lucy.
The eponymous family later gave Rutherfurd Hall to the Catholic Church in 1959 after the completion of Interstate 80 brought more traffic and noise to the area. The Church changed the Hall's name to Villa Madonna and used it as a convent for an order of nuns for five decades before selling it the town to be used as a museum and community education facility. Now listed on the National Historic Register, Rutherfurd Hall first opened to the public in 2012.
The Panther Ledge Farms estate was owned by Clendenin J. Ryan, former secretary to New York Mayor Fiorello La Guardia and politician who later ran an unsuccessful campaign for New Jersey Governor in the 1953 election.Hoff, F. David, and Mrs. Ernest Johnson, "Allamuchy Township," in Historical Sites in Warren County, ed. Richard E. Harpster (Belvidere, NJ: Board of Chosen Freeholders, 1965), p. 4. Ryan's estate acquired this name due to a rock bluff on the property, where local legend holds as the location the last mountain lion was hunted in the state.Hoff and Johnson, "Allamuchy Township," in Historical Sites in Warren County, Harpster, ed., (1965), p. 3-4. Panther Ledge Farms featured a private zoo, pheasant hatchery, helicopter, greenhouse, bloodhound kennel, and a collection of paintings Ryan bought from William Randolph Hearst.
In 1972, a left-wing group called the Allamuchy Tribe, led by activists Rennie Davis and Jerry Rubin and funded by ex-Beatle John Lennon, met at the Peter Stuyvesant Farm in Allamuchy to organize protests against the 1972 Republican National Convention. FBI surveillance of the Allamuchy Tribe led to the bureau putting pressure on Lennon to divest from political activity by threatening to deport him.
