CHADBOURNE, Paul Ansel, educator, born in North Berwick, Maine, 21 October, 1823 ; died in New York City, 23 February, 1883. After the death of his mother, in 1836, he entered the family of an acquaintance, on whose farm he worked in the summer, and in whose shop he learned the carpenter's trade in the winter, when not attending school. Afterward, when sixteen years old, he was employed as a clerk in a drug-store in Great Falls, New Hampshire, and there gained a familiarity with the names and nature of the various articles on sale, which aided him in his later chemical studies. He was prepared for College at Phillips Exeter academy, where he supported himself by copying law papers in term timeand teaching in ratation, and was graduated at Williams in 1848, with the valedictory. He then taught, and studied theology in Freehold, New Jersey, where a serious illness nearly ended his life, and entered the seminary at East Windsor, Connecticut, in 1848, but continued ill health forced him to leave after a year's study. He was principal of Great Falls high school in 1850, tutor at Williams in 1851, and, after another attack of illness, took charge of East Windsor academy. He was licensed to preach on 19 October, 1853. In the same year he was appointed professor of chemistry and botany at Williams, and in 1858 was elected to a similar professorship in Bowdoin College. He performed the duties of both professorships, and was also, during the same period, professor in the medical school of Maine and in Berkshire medical College. He also lectured at Western Reserve College, the Smithsonian institution, the Lowell institute at Boston, and at Mount Holyoke seminary. He conducted several successful scientific expeditions for the students of Williams, visiting Newfoundland in 1855, Florida in 1857, the north of Europe and the geyser region of Iceland in 1859, and Greenland in 1861. In 1859 he was transferred to the chair of natural history, where he remained till 1867. In that year he became first president of the State agricultural College at Amherst, Massachusetts, but left it for the presidency of Wisconsin university. He resigned in 1870, and, after two years among the mines in the Rocky mountains, became, in 1872, the successor of Mark Hopkins as president of Williams. Under his oversight the College prospered greatly, the number of its students was increased, and funds were liberally contributed for its support. He resigned, in 1881, to attend to important literary work, and in 1882 again became president of Massachusetts agricultural College. Dr. Chadbourne took much interest in public affairs. He was state senator from northern Berkshire in 1865 and 1866, was a delegate to the national republican convention in Cincinnati in 1876, and a presidential elector in 1880. He was actively interested in manufacturing enterprises, and was a marvel to those who knew the number of works that he carried through successfully. He was a member of various learned societies in this country and abroad. Williams gave him the degree of LL.D. in 1868, and Amherst that of D. D. in 1872. He published "Relations of Natural History to Intellect, Taste, Wealth, and Religion," four lectures before the Smithsonian in-
