20106 Morton           Discovered 1995 Aug. 20 by D. D. Balam at the National Research Council of Canada.
Donald C. Morton (b. 1933), was director of the Anglo-Australian Observatory during 1976-1986 and of the Herzberg Institute of Astrophysics in Ottawa during 1986-2000. With a rocket he made the first ultraviolet spectral observations of stars. He played a leading role in the development of the Gemini Observatory.
