Life
Life
As a young boy, Klingemann developed an interest in the theatre which would last his whole life. After he completed his education at the Collegium Carolinum in Braunschweig, he went to Jena in 1798 to study law and philosophy. There he heard lectures by Johann Gottlieb Fichte, Friedrich Wilhelm Joseph von Schelling and August Wilhelm Schlegel and became friends with Clemens Brentano. However, in 1801 he left Jena and returned to Braunschweig, where he became editor of Zeitung für die elegante Welt (Newspaper for the Elegant World). In 1810 Klingemann married Elise Anschuetz, an actress. In 1818 he became the director of the Braunschweiger Theatre. Under Klingemann the Braunschweiger theatre soon acquired a good reputation. It was here that the first performance of Johann Wolfgang von Goethe’s Faust (Part 1) was staged, on 19 January 1829. In the same year Klingemann accepted a professorship at his old school, the Collegium Carolinum but only one year later he was once again the director at the theatre. In 1831 Ernst August Friedrich Klingemann died. He is buried in the Magni cemetery in Braunschweig.
