Junker, Wilhelm, the German explorer, was born in Moscow. Having studied medicine in several German universities, he first went to Africa in 1874, when he visited Tunis and Egypt. During the years 1876-8 he penetrated as far south as the Kibbi in the course of his explorations of the Upper Nile. In the following year he went from Cairo to a point on the Welle-Makua or Ubangi River, situated in 22" 47' E. long, and 3° 13' N. lat. He spent about six years in Central Africa, being with Emin for some time, and got back to Egypt by way of Karagwe at the beginning of 1887. An English translation of his Travels in Africa between 1875 and 1878 appeared in 1890.
