6847 Kunz-Hallstein           Discovered 1977 Sept. 5 by H.-E. Schuster at La Silla.
The German lawyer Hans Peter Kunz-Hallstein (b. 1939) has been legal advisor for the European Southern Observatory for more than 20 years. A highlight of his work was the negotiations with the Chilean government over the interpretation, modification and amendment of the ESO-Chile agreement of 1963.
