85559 Villecroze           Discovered 1998 Jan. 8 by S. Banh at the Dominion Astrophysical Observatory.
The discoverer is thankful for having completed her undergraduate degree in physics and astronomy, giving her the opportunity to work as a student at the DAO and then at the Canada-France-Hawaii telescope. It was in Hawaii that she met her husband Jean-Louis Villecroze, who is the most important person in her life.
