Hans Kammler, German SS officer and engineer (died 1945)

Hans Kammler was an SS-Obergruppenführer responsible for Nazi civil engineering projects and its top secret V-weapons program. He oversaw the construction of various Nazi concentration camps, including Auschwitz, before being put in charge of the V-2 rocket and Emergency Fighter Programs towards the end of World War II. Kammler disappeared in May 1945 during the final days of the war, although conjecture about his capture or death remains.

The Schutzstaffel was a major paramilitary organisation under Adolf Hitler and the Nazi Party in Nazi Germany, and later throughout German-occupied Europe during World War II.
