1954 Kukarkin           Discovered 1952 Aug. 15 by P. F. Shajn at Simeis.
Named in memory of Boris Vasil'evich Kukarkin (1909-1977), professor of stellar astronomy and astrometry at Moscow State University for many years and a prominent specialist in the fields of variable stars and the structure of stellar systems. He was the initiator and one of the compilers of the "General Catalogue of Variable Stars", served as Vice President of the Astronomical Council of the U.S.S.R. Academy of Sciences from 1947 to 1960, as Vice President of the IAU from 1955 to 1961 and as President of IAU Commission 27 from 1951 to 1958.
