7496 Miroslavholub           Discovered 1995 Nov. 27 by M. Tichy at Klet.
Named in memory of Miroslav Holub (1923-1998), Czech immunologist, poet and essayist. His research resulted in the monograph Immunology of Nude Mice. His fine poetry combines the world of science and the world of everyday human experience, as shown, for example, in his book Supposed to Fly. Name proposed by the discoverer following a suggestion by J. Ticha.
