91604 Clausmadsen           Discovered 1999 Oct. 14 by T. Pauwels and H. Boffin at Uccle.
Claus Madsen (b. 1951), senior counsellor for international relations at the European Southern Observatory, has played a crucial role in increasing public awareness and interest in astronomy. He helped create the European Association for Astronomy Education and was key in having the U.N. pass the IYA resolution.
