Konrad Dannenberg (August 5, 1912 – February 16, 2009) was a German-American rocket pioneer and member of the German rocket team brought to the United States after World War II. ==Early years== Dannenberg was born in Weißenfels, Province of Saxony (current Saxony-Anhalt). At the age of two, he and his family moved to Hannover, where he spent his youth. He became interested in space technology while attending a lecture by Max Valier, a German pioneer in that field. He witnessed two tests with a rocket-driven railroad car in Burgwedel near Hannover and then joined Albert Püllenberg's group of amateur rocketeers. Dannenberg studied mechanical engineering at the Technische Hochschule Hannover (current University of Hannover) with emphasis in diesel fuel injection, because he recognized that injectors would also be part of the process of moving propellants into a high-pressure rocket engine. When World War II began, Dannenberg, a member of the Nazi party since 1932, was drafted into the German Army in 1939, serving first with a horse-artillery unit acquired by the German Army in Czechoslovakia.〔Aviation Week & Space Technology, 23 February 2009, "Obituaries", p. 20〕 He took part in the initial stages of the Battle of France.
