4663 Falta           Discovered 1984 Sept. 27 by A. Mrkos at Klet.
Josef Falta (1786-1847) was engineer and cartographer of the Schwarzenberg court in Český Krumlov. In 1831 he drew the first map of the panoramic views from the Kleť look-out tower opened in 1825. The name was suggested by J. Ticha.
