Hake was born on the estate of Flatow (now part of
Kremmen) in the
Margraviate of Brandenburg. He entered the
Prussian Army in 1785. In 1793, while serving in the
French Revolutionary Wars under the command of
Charles William Ferdinand, Duke of Brunswick, he distinguished himself in the
Battle of Pirmasens against France. For his actions he was awarded the order
Pour le Mérite. Hake was appointed to a post in the War Ministry in 1809, and served as Minister of War from 17 June 1810 until August 1813 when he was replaced by
Boyen (during which time he attracted much attention by his efficient preparations for war). Subsequently he, by now a Generalmajor, served as Prussian envoy at the headquarters of the
Allied Armies. King
Frederick William III of Prussia ordered him to conduct experiments into the use of the
optical telegraph. Hake, however, was opposed to optical telegraphy and devised several means of preventing the experiments from being implemented. He successfully delayed the experiments until May 1830. Hake finally left the War Ministry in 1833 and died two years later, in 1835, at
Castellammare di Stabia near
Naples in the
Kingdom of the Two Sicilies. ==Notes==
