10581 Jen{í}khollan           Discovered 1995 July 30 by P. Pravec at Ondřejov.
Jan (Jen{í}k) Hollan (b. 1955), an astronomer and environmentalist at the Brno Observatory, has deeply influenced many students and observers, including the discoverer. Sometimes in unorthodox ways, he makes a point of teaching his students to examine the most substantial points.
