Jakob Erhardt

Johann Jakob Erhardt, or John James Erhardt, (17 April 1823 – 14 August 1901) was a German missionary and explorer who worked in East Africa and India. Although he remained on or near the coast of East Africa, he contributed to European knowledge of the interior through gathering descriptions from local people who had traveled there. His map of the region stimulated dispatch of the expedition of Burton and Speke. Provided by Wikipedia
