Graft von Maltzan[1] was born on 15 April 1793 at Lissa Castle in Leśnica, Breslau, Poland.
[3] Maltzan participated in the War of the Sixth Coalition as an officer in the Prussian Garde du Corps.
Karl August Varnhagen von Ense reproduced a report by Wilhelm von Humboldt, according to which King Frederick William IV was more satisfied with Maltzan than with any other ministers, and had complete trust and confidence in him.
[5] Due to a severe mental illness, however, he was dismissed in 1842, not long before his death in Berlin in 1843.
[2] Through his daughter Charlotte, he was a grandfather of Friedrich von Pourtalès (1853–1928), who was the German ambassador to Russia when World War I broke out.
