HADLEY, JAMES (1821-1872), American scholar, was born March 3o, 1821, in Fairfield (N.Y.) . He graduated from Yale in 1842, studied in the theological department of Yale, and in 1844-45 was a tutor in Middlebury college. Then at Yale he was tutor, assistant professor, and professor of Greek, from 1851 until his death in New Haven, Nov. 14, 1872. Although he knew many ancient and modern languages, he published little. He was also an able mathematician.
His most original written work was an essay on Greek accent, published in a German version in Curtius's Studien zur griechi schen and lateinischen Grammatik. Hadley's Greek Grammar (186o; revised by Frederic de Forest Allen, 1884) long held its place in American schools. In 1873 were published his Introduc tion to Roman law (ed. by T. D. Woolsey) and his Essays, Philological and Critical (ed. by W. D. Whitney).
