18449 Rikwouters           Discovered 1994 Aug. 12 by E. W. Elst at the European Southern Observatory.
Rik Wouters (1882-1916) was a Belgian fauve painter and sculptor. Fascinated by the work of James Ensor, he started painting with a pallet knife. He chose his wife Nel as the primary model for his paintings (Woman in a white sweater, 1908) and sculptures (Domestic concerns, 1913).
