8229 Kozelský           Discovered 1996 Dec. 28 by M. Wolf and L. Sarounova at Ondrejov.
Named in honor of František Kozelský (b. 1913), a Czech telescope maker well-known for his work in collaboration with V. Gajdušek. Kozelský made a set of unique fine-mechanics tools that allowed Gajdušek to produce a number of telescope mirrors, resulting finally in the production of six excellent 0.6-m mirrors, two of them now used at the Ondřejov and the Kleť observatories in telescopes devoted to observations of minor planets. Kozelský also made a series of eight 0.2-m refracting telescopes, twenty 0.3-m reflecting telescopes, and several coelostats for small observatories in Czech Republic and Slovakia. Name proposed by the discoverers, following a suggestion by C. Polášek.
