Eugen Ludwig Bormann (6 October 1842, Hilchenbach – 4 March 1917, Klosterneuburg) was a German-Austrian historian, known for his work in the field of Latin epigraphy. He studied at the University of Bonn as a pupil of Otto Jahn and Friedrich Ritschl, and at the University of Berlin, where his influences were August Boeckh, Eduard Gerhard and especially Theodor Mommsen. As an employee of the Corpus Inscriptionum Latinarum, he spent several years conducting research in Italy. Following military service during the Franco-Prussian War (in which he was badly wounded), he taught courses in classical languages at the Gymnasium zum Grauen Kloster in Berlin.
