Louis Guingot (3 January 1864–16 December 1948) was a French mural painter and founding member of the École de Nancy (the Nancy School). He was the first French camoufleur in the First World War, credited as the inventor of military camouflage for the French army. In 1914, he created a prototype camouflaged battledress for the French army, which it rejected, only to take up the idea later for artillery guns.
