Danish poet, dramatist, and novelist whose works expressed his high moral seriousness and tragic outlook.

As a student, Hauch was strongly attracted by the idealism and spiritual aspirations expressed by Romanticism; however, after such early literary attempts as Contrasterne, to dramatiske digte (1816; “The Contrasts: Two Dramatic Poems”), he turned to the natural sciences, particularly zoology. His outlook would never escape the conflict between idealism and materialism. He took his doctorate in zoology in 1821 and then studied in Paris and Italy. In 1825 he had a foot amputated and shortly afterward attempted suicide. Hauch emerged from the spiritual crisis with a renewed desire to write. On his return to Denmark, he was successively lecturer in natural sciences at Sorø, professor of Scandinavian literature at Kiel (1846–48), and professor of aesthetics at Copenhagen from 1851 until his death in 1872.

As a dramatist, Hauch wrote mostly historical tragedies about men of destiny—Bajazet (ruler of the Ottoman Empire), Tiberius, and Gregor den Syvende (Pope Gregory VII (Gregory VII, Saint)), all in 1828—and about great Danish figures such as the king Svend Grathe (1841) and Marsk Stig (1850), an outlaw nobleman (sometimes compared to Robin Hood) exiled for his part in the murder of a king. The gloom of his plays, which are filled with suffering, is relieved somewhat by his high moral ideals and his belief in universal justice. His historical novels include Vilhelm Zabern (1834), Guldmageren (1836; “The Alchemist”), En polsk familie (1839; “A Polish Family”), and Robert Fulton (1853). But his greatest success was as a poet, particularly as a writer of odes. One of his most important poetic works was the ballad cycle Valdemar Atterdag (1861). Collections of his poems include Lyriske digte (1842; “Lyrical Poems”), Lyriske digte og romancer (1861; “Lyrical Poems and Romances”), and Nye digtninger (1869; “New Poetry”). Hauch's influence on later writers was minimal, but he is remembered for a moving recommendation that the young Georg Brandes (Brandes, Georg) succeed him as professor of aesthetics.
