5268 Černohorský           Discovered 1971 Oct. 26 by L. Kohoutek at Hamburg-Bergedorf.
Czech physicist Martin Černohorský (b. 1923) read the basic course of physics to several generation of students of the Faculty of Science of Masaryk University and served as the first rector of the Silesian University in Opava. He insists on a high standard of education and ethics in society.
