Erich Rudolf Bagge (30 May 1912, in Neustadt bei Coburg – 5 June 1996, in Kiel) was a German scientist.
Dr. Bagge developed a gaseous uranium enrichment device (Isotopenschleuse or isotope sluice)[3] for enriching the U-235 isotope content of uranium in 1944, using three methods; centrifugal force, electromagnetism and thermal diffusion.
It was pumped into the sluice, which consisted of a centrifuge and spun at great speeds to fling heavier non-fissile 238U to the periphery.
From June to December 1945, Bagge was (together with Kurt Diebner, Walther Gerlach, Otto Hahn, Paul Harteck, Werner Heisenberg, Horst Korsching, Max von Laue, Carl Friedrich von Weizsäcker, and Karl Wirtz) detained at Farm Hall near Cambridge, England.
He was also Head of the Gesellschaft für Kernenergieverwertung in Schiffbau und Schiffahrt (GKSS) near Hamburg.
