Henry Jackson (1778–1840), educator, emigrated late in the eighteenth century from his native England to Savannah, Georgia. He received a medical degree in 1802 from the University of Pennsylvania. In 1811 Jackson joined the faculty of Franklin College (later the University of Georgia) in Athens, serving as professor of natural philosophy and chemistry, 1811–20 and 1822–23, and professor of natural philosophy and botany, 1823–25 and 1826–27. The gaps in his appointment occurred when he refused to take on certain disciplinary roles required of the faculty. Jackson took a leave in 1813 from his teaching duties to serve as secretary of the American legation under William H. Crawford, the newly appointed United States minister plenipotentiary to France. When Crawford returned to the United States in 1815, Jackson stayed on as chargé d’affaires until the following year. Jackson resumed teaching at Franklin College in 1819. Crawford recommended him in 1825 for a faculty appointment at the University of Virginia, but no positions were then vacant (Lucian Lamar Knight, Georgia’s Landmarks, Memorials and Legends [1913–14], 2:368–9; Jackson, An Inaugural Dissertation on the Efficacy of Certain External Applications [Philadelphia, 1802]; Catalogue of the Trustees, Officers, Alumni and Matriculates of the University of Georgia, at Athens, Georgia, from 1785 to 1906 [1906], 5, 10; Trustees’ Minutes, University of Georgia [GU]; Chase C.
