6584 Ludekpesek           Discovered 1984 Mar. 31 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Ludek Pesek (1919-1999) was a Swiss astronomical artist and writer known for scientifically realistic illustrations published in National Geographic (ca. 1969-1973). He wrote several novels and illustrated books such as Planets of the Solar System (1963). The name was suggested by W. K. Hartmann.
