CALDWELL, Joseph, educator, born in Lammington, New Jersey, 21 April, 1773" died in Chapel Hill, North Carolina, 24 January, 1835. He was graduated at Princeton in 1791, delivering the Latin salutatory, and then taught school in Lammington and Elizabeth-town, where he began the study of divinity. He became tutor at Princeton in April, 1795, and in 1796 was appointed professor of mathematics in the University of North Carolina. He found the institution, then only five years old, in a feeble state, nearly destitute of buildings, library, and apparatus, and to him is ascribed the merit of having saved it from ruin. He was made its president in 1804, and held the office till his death, with the exception of the years from 1812 till 1817. Princeton gave him the degree of D.D. in 1816. In 1824 he visited Europe to purchase apparatus and select books for the library of the university. A monument to his memory has been erected in the grove 498 CALDWELL surrounding the University buildings. Dr. Caldwell published "A Compendious System of Elementary Geometry," with a subjoined treatise on plane trigonometry (1822), and " Letters of Curie-ton" (1825). The latter had previously appeared in a newspaper in Raleigh, and were designed to awaken an interest in internal improvements.
