Odilon Redon (20 April 1840 – 6 July 1916) was a French Symbolist artist.
Redon is perhaps best known today for the dreamlike paintings created in the first decade of the 20th century, which were inspired by Japanese art and leaned toward abstraction. His work is considered a precursor to Surrealism.
Wiki says he worked in pastels and oils, so yah, good call.
