Hans Gerhard Creutzfeldt (1885-1964) was a German neurologist. He received medical degree in 1909, attending the universities of Jena and Rostock. After a period as ship’s surgeon in the Pacific Ocean, Creutzfeldt returned to Germany, where he worked at the St. Georg Krankenhaus in Hamburg, at the neurological institute in Frankfurt, and at the psychiatric-neurological clinics in Breslau, Kiel and Berlin, and at the Deutsche Forschungsanstalt für Psychiatrie in Munich. In 1938 he was appointed professor and director of the university psychiatric and neurological division in Kiel. After the war he was rector of the Christian-Albrechts University of Kiel for six months, before being dismissed by the British occupational forces. His efforts to rebuild the university caused several conflicts with the British because he wanted to allow more former army officers to study there. In 1953 Creutzfeldt moved on to Munich to work scientifically until his death. His main contribution to neurology was the recognition of a neurodegenerative disease with Alfons Maria Jakob (1884-1931), i.e. the Creutzfeldt–Jakob disease.
