Martin Theodor von Heuglin
German explorer, 1824-1876
"Martin Theodor von Heuglin was a German explorer and ornithologist. In 1850 he went to Egypt where he learnt Arabic, and visited the Red Sea and Sinai. In 1852 he accompanied Dr. Christian Reitz, Austrian consul at Khartoum, on a journey to Ethiopia (""Travels in Northeast Africa, 1852–1853 "", 1857), and after Reitz's death was appointed his successor in the consulate. While he held this post he travelled in Ethiopia and Kordofan, making a valuable collection of natural history specimens. In 1857 he journeyed through the coast lands of the African side of the Red Sea, and along the Somali coast. In 1870 and 1871 he made a valuable series of explorations in Spitsbergen and Novaya Zemlya."
