German naturalist (1813-1887).
Moritz Wagner (Bayreuth, 3 October 1813 – Munich, 31 May 1887) was a German explorer, collector, geographer and natural historian. A contemporary of Charles Darwin, he already accepted that species are not constant in time, but his formative biological work preceded Darwin's 1859 On the Origin of Species. At the end of his university studies, Wagner devoted three years (1836–1839) to the exploration of Algiers: and graduated with a doctorate in philosophy. While his travelogues were popular, he had found his scientific training insufficient, and in the early 1840s studied for another doctorate
