Discovered on 24 September 1960 by van Houten, C. J., van Houten-Groeneveld, I., Gehrels, T. at Palomar.
Jan Olieslagers (1883-1942), Belgian aviation pioneer, caused the airport Deurne (Antwerp International Airport) to be built. In 1910 he made the first overland flight between two cities in the Netherlands. His popularity helped to promote aviation there and in Belgium. The name was suggested by W. A. Fröger.Naming citation (20010705/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
