Franz Joseph I of Austria
If Greater Germany was to prevail, the crown would necessarily have to go to Franz Joseph, who had no desire to cede it in the first place to anyone else. On the other hand, if the idea of a smaller Germany won out, the German crown could of course not possibly go the Emperor of Austria, but would naturally be offered to the head of the largest and most powerful German state outside of Austria—the King of Prussia. The contest between the two ideas, quickly developed into a contest between Austria and Prussia. After Prussia decisively won the Seven Weeks War, this question was solved; Austria lost no territories as long as they remained out of German affairs.
Christian Andreas Käsebier
In 1757, King Frederick the Great was engaged in the Seven Years' War and was conducting the Siege of Prague. He was in need of intelligence operatives who could penetrate behind enemy lines. The King personally recruited Käsebier with the promise of a pardon in return for his intelligence services. Käsebier successfully smuggled himself into the besieged city three times, but on the fourth mission became hesitant over the fear of being known now. The King threatened to send him back to prison, so Käsebier agreed to the fourth mission. He vanished soon thereafter, never to be heard from again, although it is claimed he was executed by the Austrians.
