12381 Hugoclaus           Discovered 1994 Aug. 12 by E. W. Elst at the European Southern Observatory.
The expressionistic work of the famous contemporary Flemish writer Hugo Claus (b. 1929) has been translated into several languages. He is also a well-known playwright and prominent poet. In 1983 he published his Het Verdriet van Belgii ("The Sorrow of Belgium"), which brought him international recognition.
