9239 van Riebeeck           Discovered 1997 May 3 by E. W. Elst at the European Southern Observatory.
Jan Anthoniszoon van Riebeeck (1619-1677), formerly an assistant surgeon, was sent by the Dutch authorities to southern Africa in 1652 to establish at Table Bay a fort and provisioning station for ships traveling to the East Indies. The station grew to become Cape Town.
