Born in Germany, he was a member of the Schutzstaffel (SS) during World War II, where he served as a V-weapons flight test director.
[citation needed] In 1939, he obtained his engineering doctorate with a thesis on surge voltages, and was appointed assistant professor at the university.
[11] At the end of the war, Debus and a small group of the V-2 engineers led by Wernher von Braun's brother sought out the advancing American 44th Infantry Division near Schattwald on May 2, 1945.
[4] In late 1945, Debus was transferred to Fort Bliss, Texas, under contract as a "special employee" of the U.S. Army, as were the other German rocket specialists.
He was deputy director at the Guidance and Control Branch through December 1948, when he was promoted to assistant technical director to von Braun at the Redstone Arsenal in Huntsville, Alabama.The arsenal became the focal point of the Army's rocket and space projects; larger rockets were launched first from White Sands Missile Range in New Mexico, and later from Cape Canaveral.
[1] Starting in 1952, Debus supervised the development and construction of rocket launch facilities at Cape Canaveral for the Redstone, Jupiter, Jupiter-C, Juno and Pershing military configurations continuing through 1960.
[citation needed] Beginning in 1961, Debus directed the design, development and construction of NASA's Saturn launch facilities at the north end of Cape Canaveral and adjacent Merritt Island.
