6685 Boitsov           Discovered 1978 Aug. 31 by N. S. Chernykh at the Crimean Astrophysical Observatory.
Named in memory of Vasilij Vasil'evich Boitsov (Bojtsov, 1908-1997), specialist on the technology of mechanical engineering and standardization. From 1963 to 1984 he headed the U.S.S.R. State Committee for standards and represented his country in the International Organization for Standardization, of which he served as president (1977-1979). Boitsov was an initiator and active participant in fundamental research on the creation of standard measurement systems. Name suggested by the Institute of Theoretical Astronomy and supported by the discoverer.
