Gustav Adolf Fischer (3 March 1848 – 11 November 1886, Berlin) was a German explorer of East Africa.
Gustav Adolf Fischer was born in Barmen (now part of the city of Wuppertal) in Germany on 3 March 1848. He attended high school, first in his home town and then in Cologne. On leaving school in 1869 he studied medicine and natural sciences in Bonn, Berlin and then Würzburg where he obtained a doctorate. In 1874 he joined the 1st Garde Dragoon Regiment as a doctor and was assigned to the East Frisian Infantry Regiment garrisoned in Emden.[1]
In 1876 he accompanied Clemens Denhardt's expedition to Zanzibar, where he settled as a physician. In the following year he explored Wituland and the southern Oromo country. In 1878 he continued his journey in Kenya along the Tana River to Masabubu.
With the support of the Geographic Society in Hamburg he visited the Maasai country in 1882 and penetrated from the mouth of the Pangani River to Lake Naivasha. The Maasai prevented him from advancing further. Equipped with funds by the brother of Wilhelm Junker, an explorer, who with Emin Pasha and Gaetano Casati had been lost in the equatorial provinces, he organized a relief expedition which, however, was compelled to return after reaching Lake Victoria. Shortly after his return to Germany in 1886 he died of a bilious fever contracted during his journey.
During the ten years that he spent in Africa Fischer collected many bird specimens. The descriptions of new species were usually published together with Anton Reichenow who worked at the Natural History Museum of Berlin.[2]
He is commemorated in the names of a number of birds, including Fischer's turaco (Tauraco fischeri), Fischer's lovebird, (Agapornis fischeri), Fischer's greenbul (Phyllastrephus fischeri) and Fischer's starling (Lamprotornis fischeri).[3] He is also commemorated in the names of several plants, including Gutenbergia rueppellii var. fischeri and Ligularia fischeri (Fischer's ragwort).
He also wrote many articles that were published in the Journal für Ornithologie.
