Thomas Hewitt Key, an English scholar and educator, born in Southwark, March 20, 1799. He graduated at Trinity college, Cambridge, in 1821, and for two or three years was engaged in studying medicine in Guy's hospital, London. In 1824 he accepted the professorship of mathematics in the university of Virginia, but, the climate, not agreeing with his health, he returned to England in 1827. The next year, on the founding of the university of London, he was elected to the chair of Latin, and held the post for 13 years. He then became head master of the school in the university, and professor of comparative grammar, which positions he still occupies (1874). He has contributed largely to philological literature in the way of reviews, pamphlets, essays, etc.; he had a spicy controversy with Donaldson in regard to the latter's "Varronianus;" and he was engaged for many years on a new and full " Latin-English Lexicon." He has also published a "Latin Grammar " (1843-'6), "Philological Essays" (1868), and "Language, its Origin and Development " (1874).
