Paul von Hindenburg
From Tardis Wiki, the free Doctor Who reference
Hindenberg was a German general during World War I. He commanded the Germans at the battle of Tannenberg. (PROSE: Illegal Alien) He was president in 1934 alongside the Nazi Party. (PROSE: Big Bang Generation)
Behind the scenes
General Hindenberg is presumably intended to be a reference to the real life General Paul von Hindenburg. However, Illegal Alien spells his name wrong.
