Kiefer was a professional police officer in Karlsruhe who joined the NSDAP in and the SS in January 1933. His first promotion came in September 1937 when he was made an
Untersturmführer. In May 1940 after France was occupied, Kieffer was promoted to Hauptsturmführer and became head of the BDS Paris office (first at 74 then 86 Avenue Foch), of the RSHA's Amt IVE, where he had two radio technician assistants, Obersturmführer's Ernst Misselwitz
& Heinrich Meiners. He was deputy to Karl Bommelberg, chief Gestapo officer for Counter-Espionage (Military, Economic & Political), issues. He was promoted to Sturmbannführer and took
on additional responsibilities for the IVE sub-section of the Lyons SD.
He was an expert in radio detection procedures, and was credited with the turning around (into double agents), of French & British spies in both countries during the war. He succeeded in
turning a number of British captured SOE officers in civilian clothes having given an assurance that they would not be executed in exchange for their services. He was known to have struck
captured French male prisoners during interrogations. He was captured by British troops, who tried him for war crimes in a British Military Court in Wuppertal. He was sentenced to death and
hanged* in Hameln Prison on 26th June 1947.
*There may have been a miscarriage of justice here in that British agents insisted that Kieffer had treated British captured military agents captured in civilian dress respectfully.
