D.D., an eminent Presbyterian minister and mathematician, was born in Mendham, N.J., March 24, 1805, and graduated A.B. at Princeton in 1822. In 1826 he became tutor, was licensed to preach in 1829, and in 1830 was appointed professor of mathematics in Princeton College. He filled the office with signal ability and success for fifteen years, and died, after a short illness, November 20, 1845. To a remarkable aptitude for mathematics he added an acute metaphysical turn and a taste for general literature, so that his mental culture was broad and catholic. He wrote several articles of great value in the Princeton Review, and among them one on Transcendentalism (volumes 11, 12), which was afterwards reprinted as a separate pamphlet on account of its masterly treatment of the subject. — Sprague, Annals, 4:737.
