4662 Runk           Discovered 1984 Apr. 19 by A. Mrkos at Klet.
Ferdinand Runk (1764-1834) made many landscape paintings of the Czech and Austrian countryside as the court painter of the Schwarzenberg family. A beautiful circular view from the Kleť look-out tower inspired him to make watercolors of this panoramic view in 1830. The name was suggested by J. Ticha.
