Karl Georg Albrecht Ernst Von Hake

Karl Georg Albrecht Ernst von Hake (8 August 1768 – 19 May 1835) was a Prussian general and Minister of War.

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 under the command of Charles William Ferdinand, Duke of Brunswick, he distinguished himself in the Battle of Pirmasens during the French Revolutionary Wars against France. For his actions he was later to be decorated, on 3 April 1814, with the Pour le Mérite medal with Oak leaves.

Hake served as Minister of War from 17 June 1810 until August 1813 when he was replaced by Hermann von Boyen. Returning to the field, he was wounded at the Battle of Leipzig in October 1813.

In 1819 Hake was again appointed Minister of War. 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 Naples, Italy.
