Hartmut Hoffmann (4 May 1930, Berlin – 16 April 2016[1]) was a German medieval historian.
He graduated PhD in 1954 with a thesis on Carolingian history entitled Untersuchungen zur karolingischen Annalistik.
In 1980 he published a new study on the Chronicles of Monte Cassino in Scriptores, a collection of essays published by Monumenta Germaniæ Historica - this led to several articles on the historiography of southern Italy in the Lombard and Norman eras and on the role of the papacy.
He was one of the chief editors of the Monumenta from 1982 and also was appointed to the Göttingen Academy of Sciences in 1982.
His works on Ottonian and Salic monarchy and illumination (he notably wrote on the Sainte-Chapelle Gospel Book and the Master of the Registrum Gregorii) opened the way for the publication of the Richerus Chronicles in 2000.
