Wytttenbach, DANIEL, a great Dutch scholar, born at Bern, 7th August 1746, studied at Marburg, Göttingen, and Leyden, became professor of Greek at the Remonstrant gymnasium at Amsterdam in 1771, of Philosophy at the Athenæum in 1779, and succeeded in 1799 to Ruhnken's chair of Rhetoric at the university. He retired in 1816, and died after some years of blindness at Osgest, 17th January 1820. His greatest work is the edition of Plutarch's Moralia, with rich annotations and an admirable Index Graecitatis in Plutarchi opera (Oxf. 8 vols. 1795-1830).
Other works are his Præcepta philosophicæ logicæ (1782), Economy seu selecta principium historicorum capita (1793), Vita Ruhnkenii (1800), and an admirable edition of Plato's Phædo (1810). See Mahne's Vita (1823).
His wife, Johanna Gallien, a niece of Hanau, whom he married at seventy-two, was a remarkably accomplished woman. She lived after her husband's death at Paris, was given the degree of doctor in philosophy by Marburg in 1827, and died at Leyden in 1830. Among her writings were Théagène (Paris, 1815), Das Gastmahl des Leontis (Ulm, 1821), and the romance, Alexis (Paris, 1823).
