NAUDE, (PHILIP) in biography, an able professor of mathematics at Berlin in the seventeenth and early part of the eighteenth century, was born at Metz in Lorrain, in the year 1654. At the age of about twelve, he was taken into the ser vice of the court of Eysenach, in the ca pacity of page, and attended on the young princes. In this situation his behaviour secured him the esteem of all who knew him ; and while he continued here he learned the German language, which af terwards proved of great use to him. When he had spent about four years at Eysenach, his father chose to take him home ; but how he was employed during the next fifteen years of his life we are not informed. We are only told that his father had neither the intention nor the means of affording him a learned educa tion ; but that, notwithstanding the disad vantages of his condition, having an uncon querable thirst for knowledge, he became his own master, and made considerable proficiency in different branches of learn ing, particularly in the mathematical sci ences. As he was in principle a Protest ant, when the edict of Nantes was revok ed in 1685, he left France, with his wife and young child about nine months old, and resided about two years at llanau. Hence he removed to Berlin, where he contracted an intimacy with M. Langer field, mathematician to the court, and tu tor to the pages. This gentleman, who knew how conversant he was with the sciences, advised him to open a mathe matical school, and recommended pupils to him. In 1687, he received an appoint ment to teach arithmetic and the ele ments of the mathematics at the college of Joachim : and in 1890, lie was made secretary interpreter. Upon the death of M. Langerfield not many afterwards, M. Naude succeeded him in 1696, both in his employments at court, and the pro fessorship in the Academy of Sciences.

In 1701 he was elected a member of the Academy of Sciences ; and in 1704, when the king founded the Academy of Princes, M. Naude was attached to it by a special patent, as professor of mathematics. He died at Berlin in 1729, at the age of seventy-five, highly respected for his in tegrity and general excellence of charac ter. Though the mathematics chiefly occupied his attention, he was not un acquainted with the other sciences, and as he was zealous for the religion which he professed, he had made divinity his par ticular study, and written several trea tises on religious and moral subjects. In mathematics, his sole publication was " Elements of Geometry," in quarto, writ ten in German, and printed at Berlin for the use of the Academy of Princes ; and some smaller pieces, which appeared at different periods in the " Miscellanea Berolinensia." Among his theological and moral productions were, " Sacred Meditations," 1690, limo " Evangelical Morality," 1699, in two volumes, 12mo. ; "The Sovereign Perfection of God in his Divine Attributes, and the perfect integri ty of the Scriptures, in the sense maintain ed by the first Reformers," 1708, in two volumes, 12mo. written against M. Bayle which being attacked, in a 12mo. pam phlet, he defended in "A Collection of Objections to the Treatise on the Sove reign Perfection of God, with Answers to the same," 1709, 12mo. ; " An Examina tion of two Treatises of M. de Placette," 1713, in two volumes, 12mo. ; " Dialogue in Solitude," partly translated from the Dutch of William Tecklink, 1727, 12mo.; " A refutation of the Philosophical Com mentary," 1718, 12mo. &c.
