Samuel VaughanSamuel Vaughan (April 23, 1720–1802) was a London merchant and Jamaican sugar plantation owner. An ardent supporter of the cause of American independence, Vaughan contributed to the development of several important American sites and institutions, including Mount Vernon, the State House Yard in Philadelphia, and the American Philosophical Society.
During the 1740s Vaughan established extensive commercial enterprises in London, the West Indies, and the American colonies. He strengthened his ties to America through marriage in 1747 to Sarah Hallowell (1727-1809), daughter of the wealthy Boston merchant, shipbuilder, and landowner Benjamin Hallowell.  Unlike his loyalist father-in-law, Vaughan was a passionate advocate of American liberty and a great admirer of George Washington. In London he was a member of the “Club of Honest Whigs”--a liberal coterie of intellectuals and religious dissenters (several of them, like Vaughan, Unitarians) who met to discuss science, philosophy, and social and political reform.  At his home in the English village of Wanstead, Vaughan hosted visiting American patriots such as Benjamin Franklin, who became an intimate family friend, and Josiah Quincy, Jr., to whom Franklin introduced Vaughan in 1774.
It was possibly at Wanstead that Vaughan developed the knowledge of landscape gardening that he later brought to America. At nearby Wanstead House, a magnificent Palladian residence designed by Colen Campbell, the existing formal gardens were among the first in England to be renovated (c. 1725-1771) in the Romantic, naturalistic mode that became known as the English Style. Thousands of shrubs and trees were added to the park, and architectural accents (such as a boathouse-grotto on the manmade lake and an ornamental temple that also functioned as a poultry house and keeper’s lodge) were erected on the grounds.  Analogous features were included in landscape projects Vaughan later oversaw in Philadelphia.
Within months of the conclusion of the American revolutionary war, Vaughan re-located his family to Philadelphia where, in December 1783, he met and initiated an enduring friendship with his hero, George Washington, to whom he was introduced by Benjamin Rush.  Vaughan took particular interest in the architecture, grounds, and interior decoration of Mount Vernon, advising Washington on fashionable English trends, offering to supply skilled workmen, and sending gifts such as an English fireplace mantel carved with rustic subjects. 
Vaughan also became a driving force within Philadelphia’s intellectual, civic, and scientific communities. By January 1784 he had engaged a workman to implement his ambitious plan to landscape the open green at the center of State House Square as a public garden.  He joined the American Philosophical Society in the same month, and was soon developing complementary plans for Philosophical Hall, the Society’s new building on State House Square. In a letter of March 8, 1784 Vaughan assured the Society’s founder, Benjamin Franklin, that the building would “be sufficiently ornamental not to interfere materially with the views of making a publick walk.” Vaughan initially envisioned the State House Yard as a national arboretum, with “a specimen of every sort of [tree and shrub] in America that will grow in this state.”  Vaughan purchased many of trees and shrubs from John and William Bartram, and also consulted the Bartrams’ cousin Humphry Marshall. Convinced of the public utility of [Humphry Marshall|Marshall’s]] “original botanical information of the New World” and having failed in May 1785 to gain the financial support of the American Philosophical Society (of which he was now a vice president) and the Philadelphia Society for the Promotion of Agriculture (which he had co-founded a few months earlier), Vaughan personally supervised and financed publication of Marshall’s manuscript, Arbustrum [sic] Americanum (1785), and even translated Latin terms for the English language index. 
Although Vaughan ultimately scaled back his encyclopedic plan for landscaping the State House Yard, he nevertheless assembled a great number and variety of specimens, which he laid out in accordance with the naturalistic landscape conventions he had absorbed in England. Contemporary accounts attest to Vaughan’s personal supervision of the work, and it was widely known that he was chiefly responsible for overseeing the project and financing the majority of the materials and labor.  Even travelers merely passing through Philadelphia were aware of his agency, peppering their descriptions of the State House Yard with praise for his good taste and generosity. Vaughan also received accolades for his signal contributions to the American Philosophical Society. In a letter of August 2, 1786 Benjamin Rush observed, "He [Vaughan] has been the principal cause of the resurrection of our Philosophical Society. He has even done more, he has laid the foundation of a philosophical hall which will preserve his name and the name of his family among us for many, many years to come." 
Less well known was Vaughan’s responsibility for the fashionable pleasure garden recently opened at Gray’s Tavern on the Schuylkill River. With the aid of an English gardener and a team of laborers, Vaughan had transformed the steep, wooded grounds into a romantic park known as Gray's Garden. A maze of paths meandered through informal plantings of flowers and shrubs, and featured such picturesque elements as grottoes, Chinese bridges, and a rustic hermitage that functioned as a bathhouse. 
Despite his many occupations in Philadelphia, Vaughan traveled frequently to Boston and visited other regions of the United States. In July 1786 he and Manasseh Cutler began preparations for a trip to the White Mountains, where they intended to study native flora, fauna, and minerals (Vaughan’s pet subject), aided by scientific instruments Vaughan had imported from Europe.  In 1787 Vaughan hosted two dinners for George Washington while the president was in Philadelphia for the Federal Convention, and then set off on a 1400-mile journey toMount Vernon. During his trip, Vaughan kept a journal in which he detailed the sites and natural phenomena he encountered while traveling through Pittsburgh (celebrating the 4th of July at Fort Pitt), Berkeley Springs, Williamsburg, and other towns.  During the week he spent at Mount Vernon, Vaughan made notes on the mansion and grounds and completed a sketch, from which he later produced two more detailed versions, one of which he sent as a gift to Washington. <Williams, June 1961, 273-274.> In 1790 Vaughan took his final leave of America and returned to England. Just prior to his departure, he formally requested that William Bartram — rather than an English gardener — be entrusted with maintaining the shrubs and trees at the State House Yard, asserting: “He is fully competent to the business, which I conceive not to be the case of the English Gardiner proposed, who not being acquainted with the productions of this Country & who hath neither ability to judge or means to procure the variety necessary to supply those destroyed or dead.”  From the other side of the Atlantic, Vaughan continued to exchange scientific information and specimens with Cutler, Washington, and other American friends. He also supervised the development of property inherited from his father-in-law, Benjamin Hallowell, in the town of Hallowell, Maine. As early as 1784, he had sought to establish a Unitarian community in Hallowell and he continued to promote the spiritual, agricultural, and mercantile growth of the town through family members who ultimately settled there, most notably his son Benjamin, who developed a noted garden while advancing the pioneering horticultural work that had become a family tradition. <Taylor, 1990, 34-37; Murray, 1989, 204; Nason, 1909, 50-51; Cooke, 1949, 49; Sheppard, 1865, 5-6, 12-15.>

Late October 1785—Robert Hunter traveling from Quebec: “The state-house is infinitely beyond anything I have either seen in New York or Boston, and the walk before it does infinite honor to Mr. Vaughan’s taste and ingenuity in laying it out.”
Manessah Cutler (eminent botanist and physician from Connecticut, first to record a systematic account of the flora of New England, in Philadelphia 1787 to lobby with Federal Convention): judged Vaughan’s accomplishments as “a fine display of rural fancy and elegance.” After a visit in July 1787: “It is small, nearly square, and I believe does not contain more than one acre. As you enter the Mall through the State House, which is the only avenue to it, it appears to be nothing more than a large inner Court-yard to the State House, ornamented with trees and walks. But here is a fine display of rural fancy and elegance. It was so lately laid out in its present form that it has not assumed that air of grandeur which time will give it. The trees are yet small, but most judiciously arranged. The artificial mounds of earth, and depressions, and small groves in the squares have a most delightful effect. The numerous walks are well graveled and rolled hard; they are all in a serpentine direction, which heightens the beauty, and affords constant variety. That painful sameness, commonly to be met with in garden alleys, and others work [??] of this kind, is happily avoided here, for there are no two parts of the Mall that are alike. Hogarth’s “Line of Beauty” is here completely verified. The public are indebted to the fertile fancy and taste of Mr. Sam’l Vaughan, Esq., for the elegance of this plan. It was laid out and executed under his direction about three years ago.

It is inclosed [sic], on three sides, by a brick wall…. This area has, of late, been judiciously improved, under the direction of late, been judiciously been improved, under the direction of Samuel Vaughan, Esq. It consists of a beautiful lawn, interspersed with little knobs or tufts of flowering shrubs, and clumps of trees, well disposed. Through the middle of the gardens, runs a spacious gravel-walk lined with double rows of thriving elms, and communicating with serpentine walks which encompass the whole area the whole area. These surrounding walks are not uniformly on a level with the lawn; the margin of which, being in some parts a little higher, forms a bank, which, in fine weather, affords pleasant seats. When the trees attain to a larger size, it will be proper to place a few benches under them, in different situations, for the accommodation of persons frequenting the walks. These gardens will soon, if properly attended to, be in a condition to admit of our citizens indulging themselves, agreeably, in the salutary exercise of walking.  The grounds, though not so extensive as might be wished, are sufficiently large to accommodate very considerable numbers: the objects within view are pleasing; and the situation is open and healthy. If the ladies, in particular, would occasionally recreate themselves with a few turns in these walks, they would find the practice attended with
Samuel Vaughan to Humphry Marhsall As it is my wish to plant in the State house square specimens of every tree & shrub that grow in the several states on this Continent that will thrive here, I have enclosed a sketch of such others as I have been able to procure since the 7th of last month, with a list of such others have occurred to me hitherto, but as I am unacquainted with the vast variety remaining & that you have turned your thoughts in that line, I have to request, & shall be much obliged to you for a list of such as occur to you, with directions in what state or place they are to be had; that I may lay out to procure them to plant in the fall.
