Christiane Wilhelmine Sophie von Kühn (17 March 1782 – 19 March 1797) was the love interest and eventual fiancée of the German Romantic poet and philosopher Friedrich von Hardenberg, known simply as Novalis. Her image famously appears in Novalis’ Hymns to the Night, a foundational text of the literary movement known as German Romanticism.
Sophie was the stepdaughter of Captain Johann Rudolph von Rockenthien and the daughter of Sophie Wilhelmine von Kühn.
Georg Philipp Friedrich Freiherr von Hardenberg (2 May 1772 – 25 March 1801), pen name Novalis (/noʊˈvɑːlɪs/; German: [noˈvaːlɪs]), was a German aristocrat and polymath, who was a poet, novelist, philosopher and mystic. He is regarded as an influential figure of Jena Romanticism.
Novalis was born into a minor aristocratic family in Electoral Saxony. He was the second of eleven children; his early household observed a strict Pietist faith. He studied law at the University of Jena, the University of Leipzig, and the University of Wittenberg. While at Jena, he published his first poem and befriended the playwright and fellow poet Friedrich Schiller. In Leipzig, he then met Friedrich Schlegel, becoming lifelong friends. Novalis completed his law degree in 1794 at the age of 22. He then worked as a legal assistant in Tennstedt immediately after graduating. There, he met Sophie von Kühn. The following year Novalis and Sophie became secretly engaged. Sophie became severely ill soon after the engagement and died just after her 15th birthday. Sophie's early death had a life-long impact on Novalis and his writing.
