The New International Encyclopædia/Hadley, Arthur Twining
HADLEY, Arthur Twining (1850—). An American educator, who became president of Yale University in 1899. He was born at New Haven, Conn., the son of Prof. James Hadley. He graduated at Yale in 1876, and pursued advanced studies at Yale and Berlin. In 1879-83 he was tutor in Yale College. He was university lecturer on railroad transportation from 1883 to 1886; commissioner of labor statistics for Connecticut from 1885 to 1887; professor of political science at Yale University, 1886-98; and in 1899 was made president. He was president of the American Economic Association, 1897-99. In 1885 he published Railroad Transportation: Its History and Its Laws, which at once gained him the position of an authority on the subject; it was translated into Russian in 1886, and into French in 1887. In the same year he was summoned as expert witness before the Cullom State Committee, which drafted the Interstate Commerce Law. He also published: Report on the Labor Question (1885); Report on the System of Weekly Payments (1886); Economics (1896); Education of the American Citizen (1901). He contributed numerous essays on political and economic subjects to scientific and popular periodicals, and is the author of the articles on transportation in Lalor's Cyclopædia of Political Science. President Hadley's writings place him in the first rank among American economists.
