Gustave Loiseau (1865-1935) was a French painter associated with the Post-Impressionist movement. Born in Paris, Loiseau initially trained as an architect before turning to painting in his twenties. He became interested in the works of Claude Monet and Camille Pissarro, and developed a style characterized by the use of light, color, and atmospheric effects. Loiseau often painted landscapes, particularly scenes of the French countryside, and his works are marked by a sense of tranquility and harmony with nature. He exhibited his works in several salons and was awarded several prizes, including a gold medal at the Exposition Universelle in 1900. Loiseau's works can be found in major museums around the world, including the Musée d'Orsay in Paris and the Metropolitan Museum of Art in New York.
