21682 Peštafrantišek           Discovered 1999 Sept. 9 by P. Pravec and P. Kušnirák at Ondřejov.
František Pešta (1905-1982), founder of the public observatory in the town of Sezimovo Ústí that now bears his name, was a keen popularizer of astronomy. He studied archival records of the Strkov (near Tábor, Bohemia) meteorite shower in 1753.
