was a Danish pianist and composer during the late Classical and early Romantic periods. He was a central figure of the Danish Golden Age and is immortalized in Danish cultural history through his music for Elves' Hill, the first true work of Danish National Romanticism and a concealed tribute to the absolute monarchy. To this day it is his version of this melody which is the definitive arrangement.
During his lifetime, Kuhlau was known primarily as a concert pianist and composer of Danish opera, but was responsible for introducing many of Beethoven's works, which he greatly admired, to Copenhagen audiences. Kuhlau was a prolific composer, as evidenced by the fact that although his house burned down, destroying all of his unpublished manuscripts, he still left a legacy of more than 200 published works in most genres.
Kuhlau had his breakthrough in 1814 at the Royal Danish Theatre with Røverborgen ("The Robbers' Castle"), a singspiel with a libretto by Adam Oehlenschläger.
His next dramatic works, including Trylleharpen (1817), Elisa (1820) and Hugo og Adelheid (1827), lacking drama, failed miserably. With Lulu from 1824 he finally once again experienced success with one of his singspiels. He also wrote music for performances of William Shakespeare's plays.
In 1828 he achieved his greatest success when he wrote the music for Elverhøj. It won immediate popularity, especially for its overture and the final royal anthem, his setting of Kong Christian stod ved høien Mast (King Christian Stood by the Towering Mast). In the music, Kuhlau made very effective use of Danish and Swedish folk tunes. In 1976 the overture was rearranged by Danish composer Bent Fabricius-Bjerre and used as the soundtrack in a scene in the film The Olsen Gang Sees Red. The scene depicts the Olsen Gang breaking into The Royal Theater of Copenhagen, making their way through bricked up walls using explosives and other means. The whole break-in is choreographed so it corresponds directly to the music. The scene is one of the most – if not the most – recognized in the history of Danish film.
