Louis Léopold Robert (1794-1835) was a Swiss painter.
He was born at La Chaux-de-Fonds (Neuchâtel) in Switzerland, but left his native place with the engraver Jean Girardet at the age of sixteen for Paris.
He was on the eve of obtaining the grand prix for engraving when the events of 1815 blasted his hopes, for Neuchâtel was restored to Prussia, and Robert was struck off the list of competitors as a foreigner.
