Discovered on 12 September 1999 by Pravec, P., Kusnirak, P. at Ondrejov.
Hungarian-U.S. mathematician John Ludwig von Neumann (1903-1957) influenced many branches of mathematics, computer science, physics and economics. He established the basic concepts of programmable serial digital computing and in 1944 joined the team that produced ENIAC, the first U.S. electronic computer.Naming citation (20010804/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
