Magnus Heimannsberg (1881–1962) was the commander of the Berlin Schutzpolizei during the Weimar Republic, and played a pivotal role in protecting the republic against political extremists to the right and left (i.e., against Nazis and Communists).
Hailed as an exemplar of a "new breed of people's police officers," he led repeated interventions in street protests and riots aimed at disrupting the rule of law.
Enormously popular with patrolmen, he spoke out against threats to the republic at a time when many other police leaders were preparing for a Nazi takeover.
He was illegally[citation needed] removed from his position following the dismissal of the Prussian government in the July 1932 Preußenschlag, and was briefly imprisoned by the Nazis both in 1933 and 1944.
After the Second World War, he was appointed head of police in Greater Hesse by the Americans.
