Firmin Baes (1874, Saint-Josse-ten-Noode - 1943, Brussels) was a Belgian impressionist* painter.
The son of the decorative painter Henri Baes, Firmin Baes was active as a portrait painter and a painter of still life subjects, figures, landscapes and interiors. He studied under Léon Frédéric at the Académie Royale des Beaux-Arts in Brussels between 1888-1894, and the elder artist’s influence is evident in many of Baes’s early paintings.
