German painter and draughtsman.
Runge is considered among the best German Romantic painters.
In 1799 his brother Daniel supported Runge financially to begin study of painting 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. 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. Runge’s interest in color was the natural result of his work as a painter and of having an enquiring mind.
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. In 1809 Runge completed 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 on 2 December 1810, age 33 in Hamburg.
Runge was of a mystical, deeply Christian turn of mind, and in his artistic work he tried to express notions of the harmony of the universe through symbolism of colour, form, and numbers.
