5946 Hrozný           Discovered 1984 Oct. 28 by A. Mrkos at Klet.
Named in memory of Bedřich Hrozný (1879-1952), Czech archeologist, orientalist and language scholar. He deciphered the Hittite language and proved that it is a member of the Indo-European language group. The name was suggested by M. Tichy.
