Felix Liebermann (20 July 1851 – 7 October 1925) was a Jewish German historian, who is celebrated for his scholarly contributions to the study of medieval English history, particularly that of Anglo-Saxon and Anglo-Norman law.
Felix first pursued a career in banking and the textile industry, living for a time in Manchester in the UK.
In 1873, he moved to Göttingen, Germany, to study early English history.
After his promotion in 1875 on the "Dialogue of the Exchequer" (Dialogus de Scaccario), he rapidly earned a name for himself as a medievalist with a special focus on England.
In 1896, he received honorary degrees from the universities of Oxford and Cambridge and later, the title of professor of history from the Prussian minister of justice Robert Bosse.
