O lieb, so lang du lieben kannst is a poem written by Ferdinand Freiligrath, a German writer in the 19th century. In 1847, a composer named Franz Liszt set this poem to music, and eventually turned it into his famous Liebestraum no. 3. Liebestraumis a German word that means Dream of Love, or Dreaming and Loving.
After some time in London Freiligrath came back to Germany and worked for the "Neue Rheinische Zeitung" (general editor: Karl Marx, editor of cultural pages: Georg Weerth).
In 1847, Franz Liszt set Freiligrath's poem "Olieb, solangduliebenkannst" to music--the song was later arranged by Liszt for solo piano as his "Liebestraume No. 3," which subsequently became one of his most famous piano pieces.
In 1851 he had to leave Germany again and he became the director of the London branch of the Schweizer Generalbank.
