Philipp Otto Runge (German: [ˈʀʊŋə]; 23 July 1777 – 2 December 1810) was a Romantic German painter and draughtsman. Although he made a late start to his career and is considered among the best German Romantic painters, he died young.
Runge was born as the ninth of eleven children in Wolgast, Western Pomerania, then under Swedish rule, in a family of shipbuilders with ties to the Prussian nobility of Sypniewski / von Runge family. As a sickly child he often missed school and at an early age learned the art of scissor-cut silhouettes from his mother, practised by him throughout his life. In 1795 he began a commercial apprenticeship at his older brother Daniel's firm in Hamburg. In 1799 Daniel supported Runge financially to begin study of painting under Jens Juel at the Copenhagen Academy. In 1801 he moved to Dresden to continue his studies, where he met Caspar David Friedrich, Ludwig Tieck, and his future wife Pauline Bassenge. He also began extensive study of the writings of the 17th century mystic Jakob Boehme. In 1803, on a visit to Weimar, Runge unexpectedly met Johann Wolfgang von Goethe and the two formed a friendship based on their common interests in color and art.
In 1804 he married and moved with his wife to Hamburg. Due to imminent war dangers (Napoleonic siege of Hamburg) they relocated in 1805 to his parental home in Wolgast where they remained until 1807. In 1805 Runge's correspondence with Goethe on the subject of his artistic work and color became more intensive. Returning to Hamburg in 1807, he and his brother Daniel formed a new company in which he remained active until the end of his life. In the same year he developed the concept of the color sphere. In 1808 he intensified his work on color, including making disk color mixture experiments. He also published written versions of two local folk fairy tales The fisherman and his wife and The almond tree, later included among the tales of the brothers Grimm. In 1809 Runge completed his work on the manuscript of Farben-Kugel (Color sphere), published in 1810 in Hamburg. In the same year, ill with tuberculosis,Runge painted another self-portrait as well as portraits of his family and brother Daniel. The last of his four children was born on the day after Runge's death.
