Named in memory of Prince Otto Eduard Leopold von Bismarck (1815-1898), Prussian prime minister and minister of foreign affairs and, from 1871, the so-called Great Chancellor of the German Reich. His name is closely connected with the unification of Germany and with his politics of a balance of power among the European states. Bismarck introduced a comprehensive collection of civil laws and promoted an extensive social welfare system which---in its essential parts---remains important even a century after his death. Name proposed by the first discoverer.
