6834 Hunfeld           Discovered 1993 May 11 by Y. Shimizu and T. Urata at Nachi-Katsuura.
Jan Hunfeld (1934-2009) was a Dutch journalist at Boom-Pers in Meppel, publisher of the Meppeler Courant. In the 1980s and 1990s he edited a weekly science page in the Courant, in which he included news of the activities of the Royal Dutch amateur-astronomy society. The name was suggested by T. Jurriens.
