Classen spent his career as a schoolteacher, in Wilamowitz’s words, “an amiable and venerable pedagogue. He was trained at Leipzig under Gottfried Hermann and Christian Daniel Beck (1757-1832) and at Bonn with Karl Friedrich Heinrich (1774-1838), F.G. Welcker (1784-1868), A.F. Naeke (1788-1838). Barthold Georg Niebuhr (1776-1831), who enlisted Classen’s help with his contributions to Immanuel Bekker’s (1785-1871) 25-volume edition of the Byzantine historians, "Corpus scriptorum historiae Byzantinae." Classen became close with Niebuhr and moved into his house in Easter 1827, the easier to tutor Niebuhr’s son, Marcus. Niebuhr’s house burned down in 1830 but his manuscripts and books were largely saved, salvaging notes and manuscripts for the third volume of Niebuhr’s History. When Niebuhr died the next year at the age of 54 (and his wife nine days later), Classen not only saw to his papers, but he also took in charge Marcus and his two sisters. He moved with them to Berlin, where he was an assistant at a gymnasium, and with the encouragement of F.C. von Savigny (1779-1861) completed Niebuhr’s third volume in 1832. In the next year he moved to Lübeck where Classen would teach German, Greek, and history for the next two decades. Here he became close friends with the Lübeck director and editor of Propertius Johann Friedrich Jacob (1792-1854), the historian Wilhelm Wattenbach (1819-97), Ernst Curtius (1814-96) and Georg Curtius (1820-85) and the playwright Emmanuel Geibel (1815-84) and began in earnest his study of the Greek language. In 1853 he moved to direct the Gymnasium in Frankfurt am Main where he would spend the next decade, reforming the examination system. He wrote biographies of his friend Jacob (1855) and the Renaissance humanist and teacher in Frankfurt, Jacob Micyllus (1503-58). In 1864 he returned to his hometown to direct the Johanneum. At age 70 he wrote a memoir of Niebuhr (1876). From 1864 he was patriarchal head of the Johanneum in Hamburg, until he gave way to new currents in 1874; Following his departure, he devoted himself to his eight-volume Thucydides Commentary (1862-78, 1879). Wilamowitz praised his work on Homeric usage as “some of the finest studies of their kind,” but declared that “Thucydides was the wrong subject for Classen,” although Sandys called his edition “excellent.”
