Louis Victor Antonio Artan de Saint-Martin (April 20, 1837 - May 23, 1890) was a Dutch-Belgian painter and etcher who specialized in seascapes.
He was born into a noble family in The Hague. His father was an army officer who served as an adjutant to Prince Frederick. In 1842, his family moved to Ixelles and acquired Belgian citizenship. His father died later that same year and the family moved to Brussels.
Artan began training for a military career, but quit when he was twenty and spent the next six years traveling through the Ardennes, making nature studies. During this time, he became friends with Edouard Delvaux and, after 1858, began visiting Paris, where he was influenced by the Barbizon school and the French marine painter, Eugène Boudin. Although he took some lessons from Delvaux, he remained largely self-taught. Despite this, he remained restless and spent the years 1867-1868 exploring Brittany and the shores of the English Channel. When he returned home, he became one of the sixteen co-founders the Société Libre des Beaux-Arts, an association opposed to the stylistic hegemony of the academies and salons. From 1873 to 1874, Artan lived in Antwerp, where he joined with a group of progressive painters who were fighting the influence of the Academy of Fine Arts. In 1875, he shared a studio with Félicien Rops in Paris, then settled briefly in Berck-sur-Mer, where he created some of his best-known works. After 1880, he worked in a more impressionistic style. In 1881, he became a Knight in the Order of Leopold. Two years later, he was awarded a gold medal at the International Colonial and Export Exhibition in Amsterdam.
