4837 Bickerton           Discovered 1989 June 30 by A. C. Gilmore and P. M. Kilmartin at Lake Tekapo.
Alexander W. Bickerton (1842-1929), professor of chemistry at Canterbury College, was an inspiring teacher and popularizer of science. Ernest Rutherford was one of his distinguished pupils. Bickerton was known for his "partial impact" theory of novae, which he extended to variable stars and other phenomena.
