9550 Victorblanco           Discovered 1985 Oct. 15 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Victor M. Blanco (b. 1918) was director of the Cerro Tololo Interamerican Observatory from 1967 to 1981. Under his leadership, Cerro Tololo developed into a major southern-hemisphere observatory, including the construction of the 4-meter telescope in 1975. The name was suggested by F. Vilas.
