14594 Jindrašilhán           Discovered 1998 Sept. 24 by P. Pravec at Ondřejov.
Jindřich Šilhán (1944-2000) was a major contributor to the development of visual observations in the Czech and Slovak Republics. He observed eclipsing binaries and organized a program to monitor them. His former students are some of the leaders of public observatories.
