2434 Bateson           Discovered 1981 May 27 by A. C. Gilmore and P. M. Kilmartin at the Mount John University Observatory.
Named in honor of Frank Maine Bateson, director of the Variable Star section of the Royal Astronomical Society of New Zealand since 1928. He led the site survey of New Zealand that resulted in the establishment of the Mount John University Observatory and was astronomer-in-charge there until 1968. Dr. Bateson and his wife Doris continue to support and encourage astronomy in New Zealand.
