Walter Dornberger

Major-General Dr. Walter Robert Dornberger (6 September 1895 – 26 June 1980) was a German Army artillery officer whose career spanned World War I and World War II. He was a leader of Nazi Germany's V-2 rocket programme and other projects at the Peenemünde Army Research Centre. After the war, the US Nazi scientist recruitment programme Operation Paperclip saw him move to the US, largely avoiding punishment for involvement in war crimes, to work for some decades in high positions in aerospace, including for Bell Aircraft and Boeing.
