Gustave Loiseau (1865-1935) was a French Post-Impressionist painter, remembered above all for his landscapes and scenes of Paris.
Brought up in Paris and Pontoise by parents who owned a butchers shop, Loiseau served an apprenticeship with a decorator who was a friend of the family. After suffering an attack of typhoid that brought him near to death, he 1880 explained to his parents his aspirations to become an artist. His parents, realizing that their son was unlikely to change his mind, soon sold their business and retired to Pontoise.
