209107 Šafránek           Discovered 2003 Sept. 16 by KLENOT at Kleť.
Czech experimental physicist Jaroslav Šafránek (1890-1957) designed, demonstrated (1935) and published (1936) a system for the transmission of images by low-line mechanical television. The system failed to find practical application in Czechoslovakia at that time. Later he worked in medical physics.
