Charles Da Vies, an American mathematician, born at Washington, Litchfield co., Conn., Jan. 22, 1798. He entered the military academy at West Point in 1813, graduated in 1815, and was made lieutenant of artillery. After a brief service with his regiment, he was transferred to the corps of engineers, and assigned to duty as teacher in the academy in August, 1816. In December of the same year he resigned his commission and accepted the appointment of assistant professor of mathematics, and in 1821 of natural philosophy; and in 1823 he was commissioned professor of mathematics. While engaged in preparing a series of mathematical text books his health failed, and he resigned his post and in 1837 visited Europe. After his return he became professor of mathematics in Trinity college, Hartford; but in consequence of a bronchial affection he relinquished this post for that of paymaster in the army and treasurer of West Point academy. These offices he resigned in 1845, and became professor of mathematics and natural philosophy in the university of New York. He afterward retired to Fishkill Landing, on the Hudson, to complete his series of text books, but soon resumed his professional duties, first in the normal school at Albany, and afterward in Columbia college, New York, of which institution he is now (1873) emeritus professor of higher mathematics.

His works, considered as a series, present a natural order of sequence, extending from a primary arithmetic to the higher mathematics, and including editions of Bourdon's "Algebra" and Legendre's "Geometry." He has also published treatises on surveying and trigonometry, a work on the "Logic of Mathematics," and a "Mathematical Dictionary and Cyclopaedia of Mathematical Science," written in conjunction with Prof. G. W. Peck of Columbia college.
