Carl Ferdinand Friedrich Lehmann-Haupt (11 March 1861, Hamburg – 24 July 1938, Innsbruck) was a German orientalist and historian. He specialized in Urartian research, and was co-author of Corpus Inscriptionum Chaldicarum, a corpus of Urartian inscriptions.
After receiving a degree in law at the University of Göttingen (1883), his focus turned to the history of ancient cultures — about which, he obtained a second doctorate from the University of Berlin (1886). Afterwards, he served as a research assistant in the Egyptology department at the Royal Museums of Berlin. In 1893 he obtained his habilitation and started work as a lecturer in ancient history. During his time spent at Berlin, his influences were Otto Hirschfeld, Friedrich Delitzsch and Theodor Mommsen.[1]
In 1898/99 he took part on an expedition to Armenia, where he performed extensive studies of Urartian inscriptions. In 1901 he was named an associate professor of ancient history at the University of Berlin. He later travelled to England, where in 1911 he became a professor of Greek history at the University of Liverpool, followed by an appointment as a representative to the chair of ancient history at the University of Oxford (1913/14). In 1915/16 he was a professor of ancient history at the University of Constantinople. In 1918 he relocated to Innsbruck, where he taught classes until 1935.[1][2]
In 1901 he became the first editor of Klio. Beiträge zur alten Geschichte, a journal of ancient history that he continued to edit until 1936.[1]
