Ferdinand I of Austria

His Imperial Majesty Ferdinand I Karl Leopold Joseph Franz Marchlin Emperor of Austria King of Hungary and Bohemia (April 19, 1793 - June 29, 1875) succeeded his father as Emperor and King in 1835 and abdicated in 1848.

He was both feeble-minded and sexually dysfunctional, placed on the throne by Metternich, cynically, as a puppet for Metternich's own purposes. His marriage to Maria Anna of Sardinia was never consummated, nor did he have any other liaison -- he would not have been capable of it. He is famous for his one coherent command, when someone tried to keep him from eating dumplings because his digestion could not stand it: "I'm the Emperor, and I'll have dumplings."
