Daniel Albert Wyttenbach (7 August 1746, Bern – 17 January 1820, Oegstgeest) was a German Swiss classical scholar. A student of Hemsterhuis, Valckenaer and Ruhnken, he was an exponent of the methods of criticism which they established, and with them he laid the foundations of modern Greek scholarship.
He was born at Bern, of a noble family, and was extremely proud of his lineage, particularly his descent from Thomas Wyttenbach, professor of theology in Basel at the end of the 15th and beginning of the 16th century, who had taught Huldrych Zwingli and other distinguished pupils. Wyttenbach's own father was also a theological professor of considerable note, first at the University of Bern, and then at the University of Marburg. He moved to Marburg in 1756, partly because he had studied there under the famous Christian Wolff, and embodied the philosophical principles of his master in his own theological teaching.
Young Wyttenbach entered the University of Marburg at the age of fourteen, and studied there for four years. His parents intended him to be a Lutheran pastor. The first two years were given up to general education, principally to mathematics, "philology", philosophy, and history. The professor of mathematics, August Gottlieb Spangenberg, greatly influenced young Wyttenbach. He is said to have taught his subject with great clearness, and with equal seriousness and piety, often referring to God as the supreme mathematician, who had constructed all things by number, measure and weight.
