Hindenberg was a German general during World War I. He commanded the Germans at the battle of Tannenberg. (PROSE: Illegal Alien)

Later, he was president in 1934 alongside the Nazi Party. (PROSE: Big Bang Generation) Susan Foreman knew of him as one of the big political players in Germany during the 1930s. (AUDIO: The Alchemists)

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.
