Question: Were both Grinnell College and University of Virginia founded in the 18th century? 
Context: The University of Virginia (U.Va.  or UVA), frequently referred to simply as Virginia, is a public research university and the flagship for the Commonwealth of Virginia.  Founded in 1819 by Declaration of Independence author Thomas Jefferson, UVA is known for its historic foundations, student-run honor code, and secret societies. Grinnell College is a private liberal arts college in Grinnell, Iowa, U.S., known for its rigorous academics and tradition of social responsibility.  It was founded in 1846, when a group of New England Congregationalists established the Trustees of Iowa College. Green Falls, also known as Johnston's Tavern, Turner's Store, Wright's Corner (Fork), and Dolly Wright's Corner, is a historic home located at Bowling Green, Caroline County, Virginia.  It is believed to have been built about 1710 and dating to the Colonial period.  The frame dwelling consists of a two-story, three bay, single pile, central block flanked by one-story wings.  It is considered by some historians to be the earliest surviving 18th century frame dwelling in Caroline County.  The building housed a tavern in the 18th century, a store in the mid-19th century, and a post office from 1831 to 1859.  It features massive brick exterior end chimneys.  Also on the property is a contributing 18th century meat house, late-19th century carriage house, and early-20th century barn. Nove Ware is a type of maiolica, or tin-glazed earthenware.  It was made in Nove, Italy, in the 18th century, mainly in a factory founded by Giovanni Battista Antonibon in 1728.  Near the end of the 18th century the factory became associated with another factory, in nearby Bassano, where majolica was produced in the 16th century.  Nove ware was fashioned in the Rococo style common in the 18th century, with an emphasis on light, decorative works that conformed to a sense of stylistic elegance, as opposed to the ebullient style of the baroque. Jesse Macy (June 21, 1842 – November 2, 1919) was an American political scientist and historian of the late 19th and early 20th century, specializing in the history of American political parties, party systems, and the Civil War.  He spent most of his professional career at his alma mater, Grinnell College. Green Springs was built in the late 18th century on lands in Louisa County, Virginia assembled by Sylvanus Morris.  His son Richard (c.1740-1821) developed 1746 acre near the mineral springs that gave the property its name and built the two-story frame house.  The property stands in an unusually fertile region of central Virginia, surrounded by a number of 18th and 19th century farms and plantations.  The district has been designated a National Historic Landmark district, comprising about 14000 acre under scenic easement protection. Elk Hill is a historic house and farm complex located near Nellysford, Nelson County, Virginia.  It is one of the earliest extant farms in Nelson County.  The 173 acre rural farm bounded in part by the South Fork of the Rockfish River and Reid’s Creek.  The main house is a substantial two-story, three-bay wide frame dwelling with a central hall plan, with the original portion built between 1790 and 1810.  The house underwent a series of 19th-century additions and a major remodeling in 1902 in the neoclassical style.  The contributing outbuildings include: smokehouse, built in the last quarter of the 18th century; tobacco barn, built circa 1790-1810; 19th century chicken house, two seat outhouse, and double crib barn; garages built in 1902 and in 1955; and a stone boundary/retaining wall, built in the last quarter of the 18th century. Arvonia is an unincorporated community in Buckingham County, Virginia founded mainly by Welsh immigrants during the 19th century.  The town derives its name from the popular port city of Caernarfon, Wales.  Its major industry has been slate mining.  The slate is known primarily for its color and durability, and is featured on many prominent American buildings, such as the Smithsonian Castle, and the University of Virginia. The Prussian education system refers to the system of education established in Prussia as a result of educational reforms in the late 18th and early 19th century, which has had widespread influence since.  It is predominantly used as an American political slogan in educational reform debates, since it was adopted by all American K–12 public schools and major universities as early as the late 18th century, and is often used as a derogatory term for education in the service of nation-building, teaching children and young adults blind obedience to authority, and reinforcing class and race prejudice.  The actual Prussian education system was introduced as a basic concept in the late 18th century and was significantly enhanced after Prussia's defeat in the early stages of the Napoleonic Wars.  The Prussian educational reforms inspired other countries and remains important as a biopower in the Foucaultian sense for nation-building.  Compulsory education on the Prussian example was soon mirrored in Scandinavia, and United States started to adopt the Prussian example.  Early American adopters include Daniel Coit Gilman, who set up The General Education Board, later renamed The Rockefeller Foundation, and first president of Johns Hopkins, John Dewey at the University of Chicago, James McKeen Cattell at The University of Pennsylvania and Columbia University, Henry Philip Tappan at The University of Michigan, James Earl Russell at the New York College for the Training of Teachers, and many more.  France and the UK failed to introduce similar systems until the 1880s. Described as “one of the most important late 18th century plantation houses in Virginia” by the Senior Architectural Historian, Commonwealth of Virginia Department of Historic Resources, Mount Ida was built c. 1795 by William Cannon, on a hill overlooking the south side of the James River near New Canton in Buckingham County, Virginia.  The site was near the northwest corner of Cumberland County and across the river from Bremo.  In 1805 Cannon sold the property to the legendary land baron David Ross, who subsequently sold the property to William Leitch, a Buckingham merchant.  Around 1850, Leitch, laden with tobacco export wealth, added a major addition to the east side of the house, as evidenced by the difference in siding, window size and interior trim.  The intricate, extraordinary interior woodwork with its elegant and unique composition was designed by a master builder, modeled after patterns found in two early 18th century architectural treatises, William Pain’s Science of Architecture and Asher Benjamin’s Practical House Carpenter.  While Leitch family lore contends that Irish immigrants performed the work, scholars are of the opinion that the work may have been done by the same skilled craftsman who markedly similar woodwork at Woodlands (1789-1794), originally in Amelia County and since relocated to Goochland County.  The interior of Mount Ida has been compared to that at Plain Dealing Plantation (circa late 1780’s), another exemplary plantation home a few miles away in Keene.
