7490 Babička           Discovered 1995 July 31 by P. Pravec at Ondřejov.
Named in memory of Marie Macháčová (1922-1998) and Marie Petrželová (1912-1998), the grandmothers of the discoverer's wife; and Emilie Dudková (1914-1977) and Aloisie Pravcová (b. 1917), the grandmothers of the discoverer. This naming is also devoted to all grandmothers, who traditionally have a major role in bringing up children in the Czech nation. This role is also reflected in the novel "Babička" ("Granny"), written by Božena Němcová, based on her own childhood experience.
