8832 Altenrath           Discovered 1989 Mar. 2 by E. W. Elst at the European Southern Observatory.
Named in memory of Henricus Hubertus Altenrath (1832-1892), initiator and first director of the "Nijverheidsschool", a well-known Antwerp school for the teaching of technical professions. Under his direction, the school began teaching in Flemish, which was not common at that time. His name is still honored by the Association "Henric Altenrath". The discoverer has taught for many years at this school.
