114991 Balázs           Discovered 2003 Aug. 26 by K. Sárneczky and B. Sip{o´´}cz at Piszkéstet{o´´}.
Lajos G. Balázs (b. 1941) has been the director of the Konkoly Observatory since 1996. His main field of research is the study of statistical phenomena in astronomy, with particular application to \gamma -ray bursters, interstellar matter and star formation. He was the codiscoverer of supernova 1969B.
