Albert Brackmann (24 June 1871, Hanover – 17 March 1952, Berlin-Dahlem) was a leading nationalist German historian associated with the Ostforschung, a multi-disciplined organisation set up to co-ordinate German propaganda on Eastern Europe. After Nazis were elected to power, he became one of the chief propagandists in service of the regime. In this position he supported Nazi genocidal policies, ethnic cleansing and anti-semitism.
