27960 Dobiáš           Discovered 1997 Sept 21 by L. Šarounová at Ondřejov.
Václav Dobiáš (1909-1978), Czech composer, organizer of musical life and pedagogue, educated a number of composers, including the discoverer's father. His cycle of songs Praho jediná ("Prague, the Only One") is a beautiful apotheosis of the Czech city.
