Benjamin Vaughan (April 19, 1751 – December 8, 1835) was an agriculturalist, physician, politician, and merchant. He is chiefly known for fostering diplomatic relations and cooperation in matters of science between Britain and America, and for developing the town of Hallowell, Maine.
Born in Jamaica where his father, the British merchant and planter Samuel Vaughan, owned two large plantations, Benjamin Vaughan was educated in Britain and pursued degrees in law and medicine at Cambridge and the University of Edinburgh. He gravitated toward a group of radical thinkers (among them Sir Joseph Banks, Joseph Priestly, and Jeremy Bentham) who shared his unorthodox views on religion, politics, and science.  Vaughan was sympathetic to the cause of American independence and sought out prominent Americans in London, including Thomas Jefferson, Benjamin Franklin, John Adams, and William Bingham. At the outset of the revolutionary war, he began editing Franklin’s writings (published in 1779 as Political, Miscellaneous, and Philosophical Pieces) and he was instrumental in convincing Franklin to publish an autobiography.  As private agent to the Earl of Shelburne (then British Prime Minister), Vaughan facilitated peace negotiations between Britain and America in 1782. He thereafter served as an important conduit for the flow of scientific information and materials between the two countries, sending books and scientific equipment to Ezra Stiles (then president of Yale University) and the American Philosophical Society (which elected him a member in 1786), and carrying out a lengthy correspondence focused on medical and scientific news with Benjamin Rush.  Vaughan had presumably been introduced to the subjects of botany and agricultural improvement by the naturalist John Reinhold Forster, who had been one of his teachers at the Warrington Academy in England. He conferred frequently on these topics with Sir Joseph Banks and with naturalists in the British West Indies.  He was actively engaged in the exchange of seeds between America, the West Indies, Britain, and France. During the 1780s and early 1790s, in addition to disseminating among his friends in England specimens from John Bartram’s “list of American plants fit for this country,” he arranged for West Indian rice seeds to be sent to a number of his correspondents in Virginia (including Thomas Jefferson and George Washington) and South Carolina (including Henry Laurens and Charles C. Pinckney). 
Vaughan’s support of republicanism and his sympathy for the French Revolution placed him at odds with the British government. In 1794 he fled to France, taking refuge at the country estate of Thomas Jefferson’s brother-in-law, the American counsel-general, Henry Skipwith of Hors du Monde, Virginia.  Three years later, Vaughan immigrated to America with the intention of leading the exemplary life of “a peasant” in rural Hallowell, Maine. In addition to laying out extensive gardens, he developed a large portion of the property as a model farm, building greenhouses and planting orchards in order to experiment with the cultivation of a wide range of plant specimens: apple, pear, and stone-fruit scions imported from England; fig and grape cuttings that his brother John sent from France; potatoes imported from continental Europe; Swedish turnips; and Siberian wheat. . He established a successful commercial nursery and employed an English mechanic to set up New England’s largest cider mill and press. Dr. Vaughan sought to overcome local resistance to his family’s practice of “book farming” by conducting information sessions at his farm and by generously sharing plant and seed specimens. 
As a conduit for the exchange of scientific information, Vaughan was as active in his remote Maine outpost as he had been in London, publishing articles on his agricultural experiences and penning letters to correspondents as far flung as David Hosack in New York, Benjamin Rush in Philadelphia, and David Ramsay in South Carolina.  In 1800 he published an “augmented” version of The Rural Socrates, or, An Account of a Celebrated Philosophical Farmer Lately Living in Switzerland and Known by the Name of Kliyogg, which concerned a Swiss peasant who transformed a failing farm into a productive enterprise through attention to proper methods.  Over the course of his long friendship with Bowdoin College professor Parker Cleaveland (cousin of Nehemiah Cleaveland), Vaughan contributed scientific apparatus and collections to help promote study of the natural sciences at Bowdoin.  In 1805 he began campaigning to raise money for the establishment of a natural history professorship and experimental botanic garden at Harvard.  By the time of his death, Vaughan had assembled one of the largest private libraries in New England, estimated at between 10,000 and 12,000 volumes, primarily imported from England and France.  According to the Hallowell journalist Samuel Lane Boardman (1836-1914), Vaughan’s library contained “many rare and valuable English works on agriculture and rural economy not often met with in public libraries of this country.”  A number of these volumes, heavily marked with his annotations, formed part of the large donations Vaughan made to New England institutions, including Harvard University and Bowdoin College. 
- "With this interesting family we spent the evening and the succeeding morning until 11 o'clock; and enjoyed in a high degree the combined pleasures of intelligence, politeness, and refinement. Mr. V. had proposed to carry us to a fine view of the country, furnished by a neighbouring eminence: but a mist, rising from the river during the night, precluded us from this gratification, until it became so late, that we were obliged to pursue our journey."

- " Mr. Vaughan intended his residence here from the first to be permanent; and at once cultivated his grounds, and attended to the duties of a citizen, but without engaging in party disputes, as many do when they arrive in the United States. He wisely kept aloof from all political parties. He encouraged a taste for agriculture, and prepared a large nursery of fruit trees, which he distributed gratis in different parts of that new country, where they were much wanted. For twenty years past, the fruit in and near Hallowell, and in the neighboring towns, has been abundant — owing in a great measure to the generous efforts of Mr. Vaughan. He and his family distributed a great number of books for children in that part of the country; and urged the forming of schools in all the new plantations. The benefits have been extensive, and hardly can be duly appreciated."

- "Here [at Hallowell] he occupied himself in study in an extensive correspondence with distinguished persons on both sides the Atlantic and in promoting the welfare of the place and of the people among whom he had fixed his residence.... The agriculture of the country was indebted to Dr Vaughan for the introduction of new varieties of seed and plants and for the importation of improved breeds of animals. His fortune was considerably diminished by the large sums expended upon his farm and nursery...."

- "Dr. Vaughan was fond of horticulture, and was one of the pioneers of New England in the improvement of fruits and cereals. He imported choice seeds, which he was ever ready to impart to his neighbors...He also took great pains in promoting agriculture, and introducing from abroad the best kinds of stock on his farm; superior oxen and more productive cows were not to be seen."

- "A gentleman who was acquainted with Dr. Vaughan, and from whom I have obtained some incidents of his life, says it was his custom in fair weather to walk a certain number of miles, each day, for exercise; and when the weather would not admit of his being out of doors, he would walk upon his piazza as many hours as would be equivalent to the distance walked."
