Friedrich 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 Kuhlau was a prolific composer, as evidenced by the fact that although his house burned down, destroying all of his unpublished manuscripts, he still left a legacy of more than 200 published works in most genres.
Kuhlau was born on 11 September 1786 just south of Lüneburg in Uelzen district of Lower Saxony (Germany). At the age of seven, he lost his right eye when he slipped on ice and fell. His father, grandfather, and uncle were military oboists. Even though Kuhlau was born to a poor family, his parents managed to pay for piano lessons. Later he studied the piano in Hamburg where he also had his debut as a pianist in 1804.
In 1810, he fled to Copenhagen to avoid conscription in the Napoleonic Army, which overwhelmed the many small principalities and duchies of northern Germany, and in 1813 he became a Danish citizen.
