Prof. Klaus Gutenberg

It goes without saying that not every German supports the Third Reich, and Gutenberg, a German refugee and a brilliant scientist, emphatically condemns Hitler's methods and Nazi ideology. Though Lt. Rojas caught him as a hostage in the spring of 1939, Gutenberg pledged his loyalty to the Resistance. At headquarters, he assists the Allies by conducting experiments, deciphering encrypted files, and sharing his knowledge of the Reich's plans. That knowledge is a major advantage over the Axis, so hopefully he's chosen the winning side — his fate would be unspeakable if the Nazis were to recapture him.
