Ernst Sagebiel (2 October 1892 inBraunschweig (Brunswick) – 5 March 1970 inBavaria) was a Germanarchitect.


Sagebiel was asculptor's son, and after hisAbitur in 1912, he began his studies inarchitecture at theBraunschweig University of Technology. He eventually finished his studies in 1922, after they were interrupted by his participation in theFirst World War, which included a stint in aprisoner-of-war camp. In 1924, he joined Jakob Körfer's architectural bureau inCologne. In 1926 he was awarded adoctorate ("Promotion"). In 1929, Sagebiel took a job inBerlin as a project leader andchief executive officer at the architectErich Mendelsohn's office, but in 1932, he left because of thesevere economic climate in Germany. He then worked as aconstruction foreman.
AfterAdolf Hitler and theNazis seized power in 1933, Sagebiel became a member of theNSDAP andSturmabteilung (SA).
Already by 1933, Sagebiel had, at his brother's suggestion, come to be at theDeutsche Verkehrsfliegerschule ("German Commercial Flyers' School"), which was a front organization involved more with Germany'sair force buildup than with commercial flying. As of 1934, he was being trusted with planning, as well as overseeing construction of, numerous Luftwaffebarracks (in Döberitz, Berlin-Gatow and Kladow, to name a few) as leader of the special works unit.
Sagebiel's austere building style, which when compared toAlbert Speer's rather classicist tendencies came across as very stark and linear, was described as "Luftwaffe modern", owing to his close association with theLuftwaffe. With his earlier building of the Reich Air Transport Ministry forHermann Göring, which came earlier than Albert Speer's exertion of influence on the National Socialists' architectural parlance, Sagebiel set a trend that would be recognizable throughout the Third Reich. From 1938, he was directly subordinate to the Air Transport Minister, Hermann Göring, and as a result was considered among the Reich's most important architects. In the same year, he became aprofessor at theTechnische Hochschule Berlin.
The outbreak ofwar against theSoviet Union in 1941 put an end to all of Sagebiel's building plans.
