From 1930 to 1932, Albert Carl Grzesinski was a Police President. In 1931, as Berlin's Police President, he tried to gag Hitler, ordering him deported as an undesirable alien, but Chancellor Heinrich Brüning did not sign the order. He was removed from his position following the 1932 Preußenschlag (Prussian Coup), when he was succeeded by the former Police President of Essen, Kurt Melcher. According to Christopher Clark, he referred to Hitler as 'the foreigner' and found it 'lamentable' that he should be negotiating with the government 'instead of being chased away with a dog whip'
