Friedrich KuhlauFriedrich Daniel Rudolf Kuhlau (German; Danish sometimes ''Frederick Kulav'') (11 September 1786 – 12 March 1832) was a German-born Danish composer during the Classical and 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 Kuhlau was a prolific composer, as evidenced by the fact that although his house burned down, destroying all of his unpublished manuscripts, he still left a legacy of more than 200 published works in most genres.
