Gustave Moreau (1826-1898) was a French Symbolist painter. He's known for his mythological subjects in a highly romantic style. He is also known for the use of Oriental color harmonies within some of his work.  In 1892 he became a professor at the Ecole des Beaux-Arts and proved to be a great teacher. His pupils included Marquet and Matisse, but his favorite was Rouault, who became the first curator of the Moreau Museum in Paris (which was his former home).
