Louis Clesse was a Belgian who was born and died in Elsene, Brussels. Clesse became celebrated for his post-impressionistic paintings and watercolors of landscapes and harbor scenes. He studied at the Academy of Ixelles (or Elsene). With advice and encouragement of A.E. Bastien Claus, he made his exhibition entry in the Brussels Salon of 1907. He painted landscape in the Zonien forest in the Zennevaliei and Ontario. Clesses formed a workshop in 1932 Oudenburg the market (now an upscale restaurant coffee shop: Louis Clessé) from which he studied the coast, the port, countryside villages in and around Bruges. He was a printmaker of handsome architectural/landscape aquatints and lithographic images. His works received a retrospective exhibition in 1969 in Oudergem and in 1973 in Brussels. He was a member of the Cercle et Artistque Literary (Cercle Gaulois), was a member of the purchasing committee of the Museum of Ixelles (Elsene). His works are represented in the Museum of Antwerp Brussels, Ixelles, Reims, Algiers, Cairo, Rio de Janeiro, San Francisco and Tokyo. His paintings have been auctioned by Doyle, Christies and Galerie Moderne.
