An artist of the French school, Rieder typically executed landscapes, genre scenes, interiors, and occasionally historical subjects. His work is said to resemble the styles of both the Post-Impressionist and Intimist schools, often depicting very intimate scenes inside the home. A student of the illustrious Alexandre Cabanel at the Beaux-Arts in Paris, he received a fabulous foundation for a very successful career in the fine arts.
Rieder exhibited rather regularly in Paris, primarily with the Salon des Artistes Francais, of which he was made an associate in 1894. They awarded to him a third place medal in 1898, followed by a second place medal in 1899. In 1900, he won a bronze medal at the Exposition Universelle in Paris. He also exhibited a good number of paintings at the Walker Art Gallery in Liverpool.
So remarkable in Rieder's canvases is the very distinct quality of light he came to master. His scenes are calm, peaceful and exquisite at the same time. Also notable is his wonderful use of color and precise brushwork accentuated by a strong grasp of perspective.
