Curt Johan Vogel was an SS officer in charge of an expedition to find the crystals of the Shintay. In the guise of Doctor Vogel, head of the Dutch Pharmaceutical Expedition (ostensively searching for rare orchids) he rescued Indiana Jones and Marion Ravenwood from quicksand and lavishly entertained them in his camp. Indy was suspicious about the quantity of munitions in the camp and while snooping about was caught by Vogel who revealed that he was indeed a Nazi Colonel. Indy and Marion managed to escape but Vogel recaptured them and together they were in turn all captured by the Shintay. Vogel and all of his people were killed as the Nazis attempted to steal the crystal shards.
