MÖHLER, LUDWIG. — Catholic historian, born on 16 July 1883 in Mannheim, died on 25 December 1943 in Freiburg im Breisgau. Ordained a priest, from 1910 he devoted himself to philological and historical studies, earning a doctorate in philosophy in 1912 with a thesis on Cardinals Giacomo and Pietro Colonna, which formed a volume published in 1914.
Turning to the study of the history of the papacy in the 14th century, he joined the Roman Historical Institute of the Görres-Gesellschaft and worked there from 1912 to 1915, deepening his research on the revenues of the Apostolic Chamber during the time of Pope Clement VI (*Die Einnahmen der apostolischen Kammer unter Klemens VI.*); however, due to the difficulties of the war and the post-war period, the work was not published until 1931. At the outbreak of the First World War, M. returned to his homeland and served as a military chaplain. At the same time, he resumed his studies assiduously and earned his doctorate under Göller in 1918, presenting a thesis on Cardinal Bessarion. Professor of ecclesiastical history at Münster, Würzburg (from 1935) and Freiburg (from 1939), he consistently directed his studies toward the personality of Bessarion, publishing between 1923 and 1941 three volumes: the first of a broadly biographical and critical character (*Kardinal Bessarion als Theologe, Humanist und Staatsmann*, 1923), the other two providing the first critical Greek edition of the work *In culminatorem Platonis*, as well as other known texts and letters addressed to or written by Bessarion.
