James Hadley devoted his career mainly to traditional philological interests and the teaching of both graduate and undergraduate students. His principal specialties were Greek and Roman law (on which he lectured at Harvard and Yale), but he was expert in Latin, Greek, Hebrew, Arabic, and Sanskrit and given also to mathematics and history. His colleague William Dwight Whitney praised the breadth of his knowledge, the depth of his memory and the wisdom of his judgment and called him the “best and soundest” American classicist. Hadley was more famous as a gifted teacher than as a productive scholar. His essays were published posthumously by Whitney, and his essay “On the Nature and Theory of Greek Accent” was translated into German and was well received.
