HADLEY, ARTHUR TWINING (1856- ), American political economist and educationist, president of Yale University, was born in New Haven, Connecticut, on the 23rd of April 1856. He was the son of James Hadley, the philologist, from whom, as from his mother—whose brother, Alexander Catlin Twining (1801-1884), was an astronomer and authority on constitutional law—he inherited unusual mathematical ability. He graduated at Yale in 1876 as valedictorian, having taken prizes in English, classics and astronomy; studied political science at Yale (1876-1877) and at Berlin (1878-1879); was a tutor at Yale in 1879-1883, instructor in political science in 1883-1886, professor of political science in 1886-1891, professor of political economy in 1891-1899, and dean of the Graduate School in 1892-1895; and in 1899 became president of Yale University—the first layman to hold that office. He was commissioner of the Connecticut bureau of labour statistics in 1885-1887. As an economist he first became widely known through his investigation of the railway question and his study of railway rates, which antedated the popular excitement as to rebates. His Railroad Transportation, its History and Laws (1885) became a standard work, and appeared in Russian (1886) and French (1887); he testified as an expert on transportation before the Senate committee which drew up the Interstate Commerce Law; and wrote on railways and transportation for the Ninth and Tenth Editions (of which he was one of the editors) of the Encyclopaedia Britannica, for Lalor’s Cyclopaedia of Political Science, Political Economy, and Political History of the United Stales (3 vols., 1881-1884), for The American Railway (1888), and for The Railroad Gazette in 1884-1891, and for other periodicals. His idea of the broad scope of economic science, especially of the place of ethics in relation to political economy and business, is expressed in his writings and public addresses. In 1907-1908 he was Theodore Roosevelt professor of American History and Institutions in the university of Berlin.
Among his other publications are: Economics: an Account of the Relations between Private Property and Public Welfare (1896); The Education of the American Citizen (1901); The Relations between Freedom and Responsibility in the Evolution of Democratic Government (1903, in Yale Lectures on the Responsibilities of Citizenship); Baccalaureate Addresses (1907); and Standards of Public Morality (1907), being the Kennedy Lectures for 1906.
HADLEY, JAMES (1821-1872), American scholar, was born on the 30th of March 1821 in Fairfield, Herkimer county, New York, where his father was professor of chemistry in Fairfield Medical College. At the age of nine an accident lamed him for life. He graduated from Yale in 1842, having entered the Junior class in 1840; studied in the Theological Department of Yale, and in 1844-1845 was a tutor in Middlebury College. He was tutor at Yale in 1845-1848, assistant professor of Greek in 1848-1851, and professor of Greek, succeeding President Woolsey, from 1851 until his death in Hew Haven on the 14th of November 1872. As an undergraduate he showed himself an able mathematician, but the influence of Edward Elbridge Salisbury, under whom Hadley and W. D. Whitney studied Sanskrit together, turned his attention toward the study of language. He knew Greek, Latin, Sanskrit, Hebrew, Arabic, Armenian, several Celtic languages and the languages of modern Europe; but he published little, and his scholarship found scant outlet in the college class-room. His most original written work was an essay on Greek accent, published in a German version in Curtius’s Studien zur griechischen und lateinischen Grammatik. Hadley’s Greek Grammar (1860; revised by Frederic de Forest Allen, 1884) was based on Curtius’s Schulgrammatik (1852, 1855, 1857, 1859), and long held its place in American schools. Hadley was a member of the American Committee for the revision of the New Testament, was president of the American Oriental Society (1871-1872), and contributed to Webster’s dictionary an essay on the History of the English Language. In 1873 were published his Introduction to Roman Law (edited by T. D. Woolsey) and his Essays, Philological and Critical (edited by W. D. Whitney).

HADLEY, a township of Hampshire county, Massachusetts, U.S.A., on the Connecticut river, about 20 m. N. of Springfield, served by the Boston & Maine railway. Pop. (1900), 1789; (1905, state census), 1895; (1910) 1999. Area, about 20 sq. m. The principal villages are Hadley (or Hadley Center) and North Hadley. The level country along the river is well adapted to tobacco culture, and the villages are engaged in the manufacture of tobacco and brooms. Hadley was settled in 1659 by members of the churches in Hartford and Wethersfield, Connecticut, who were styled “Strict Congregationalists” and withdrew from these Connecticut congregations because of ecclesiastical and doctrinal laxity there. At first the town was called Norwottuck, but within a year or two it was named after Hadleigh in England, and was incorporated under this name in 1661. Hopkins Academy (1815) developed from Hopkins school, founded here in 1664. The English regicides Edward Whalley and his son-in-law William Goffe found a refuge at Hadley from 1664 apparently until their deaths, and there is a tradition that Goffe or Whalley in 1675 led the people in repelling an Indian attack. From 1675 to 1713 Hadley, being in almost constant danger of attack from the Indians, was protected by a palisade enclosure and by stockades around the meeting-house. From Hadley, Hatfield was set apart in 1670, South Hadley in 1753, and Amherst in 1759.
