Šarounová at Ondřejov. Petr Kalaš, alias Bondy (1944-2000), was leader of the Prague Scout section Maják ("Lighthouse") and a lover of historical American cars. Bondy was appreciated by friends for his lack of reserve, his strong mind, kindness and sense of humor. He died exactly three years after the discovery of this minor planet.
