19612 Noordung           Discovered 1999 July 17 at the Črni Vrh Observatory.
At the end of 1928 Herman Potočnik (1892-1929) published under the pseudonym Hermann Noordung a visionary work entitled Das Problem der Befahrung des Weltraums---der Raketen-motor. In this work he was the first to detail a technical description of a space station in a geostationary orbit and its applications.
