4409 Kissling           Discovered 1989 June 30 by A. C. Gilmore and P. M. Kilmartin at Lake Tekapo.
Warwick M. Kissling (b. 1957) is an innovative applied mathematician. His computations have allowed the follow-up and recovery of several new minor planets. Like many New Zealanders, he is fond of clambering around mountains in his spare time.
