Johannes "Hans" Klein was with ReichsprotektorReinhard Heydrich on May, 27, 1942, the day two Czech partisans attempted to assassinate Heydrich in Prague.[1] Klein's steadfast demeanor and clear thinking impressed Heydrich, who kept Klein as his aid-de-campe. When Heydrich began preparing a resistance in the face of a possible Allied invasion of Germany in 1943, Klein became Heydrich's close confidant.[2]
When the Allies did occupy Germany in 1945, Klein followed Heydrich into hiding in the Alpine Redoubt.[3] Heydrich frequently shared ideas with Klein for further terrorizing the Allies.[4] In 1946, Klein escorted Heydrich on one of the few missions the Reichprotektor personally oversaw--the kidnapping of several German scientists from British custody.[5] He stayed with Heydrich until the bitter end, which came in 1947 when the United States Army finally located Heydrich's hideout.[6] Heydrich was killed, but Klein survived, proudly acknowledging his role in assisting Heydrich.[7]
