Doctor Jürgen Voller, later known under the cover identity of Professor Schmidt, is the main antagonist of the 2023 action-adventure film Indiana Jones and the Dial of Destiny, the fifth and final installment of the Indiana Jones film series.
He is a former Schutzstaffel officer who was recruited into the NASA's Apollo program following World War II, assisting them in beating up the Soviet Union in the Space Race. However, Voller actually longs to use Archimedes' Dial to erase Adolf Hitler's mistakes by altering history to ensure the ascendancy of a new Führer, likely himself, to lead the Third Reich to victory and change the outcome of World War II.
