15811 Nüsslein-Volhard           Discovered 1994 July 10 by F. Borngen at Tautenburg.
German biologist Christiane Nüsslein-Volhard (b. 1942) intensely studied the development stages of the fly Drosophila melanogaster and shared the 1995 Nobel prize for medicine for her epoch-making discoveries of the fundamental genetic steering mechanisms of embryogeny.
