Jørgen Valentin Sonne (24 June 1801, Birkerød – 24 September 1890, Copenhagen) was a Danish genre painter; known primarily for his battle scenes.
His father Jeppe (1771–1833) was a copperplate engraver for the Royal Mint. He originally intended to pursue a military career and enrolled at the Royal Danish Military Academy, but left after a year and went to the Royal Danish Academy of Fine Arts instead. At the same time, he began to work in the studios of Christian David Gebauer, mostly making copies of the old Dutch Masters. He also painted some original pictures and had a small showing in 1818.
In 1828, he received a travel stipend from the Academy that allowed him to visit Munich, where he became an apprentice of the history painter, Peter von Cornelius. He stayed there for three years and made several trips into the mountains to do landscapes, which are not among his best works.
When he left Munich, he was able to obtain further support for studies in Rome. While there, he made numerous hunting trips as an excuse to observe the rural peasants and their daily habits. During these trips he made sketches that he would use as inspiration throughout his career.
He returned to Denmark in 1841; producing works based on his Italian studies as well as ones depicting the Danish peasantry. In 1848, following the start of the First Schleswig War, he was given permission to accompany the army to Southern Jutland. Many of the soldiers were impressed by the way he calmly sketched while bullets flew around him. During the Second Schleswig War, despite being sixty-three years old, he was with the army again, at the Battle of Dybbøl and in Sønderborg when the city was under bombardment.
