Waffen SS Sturmbannführer (Major) Hans Josef Kieffer {b. December 4. 1900 – d. June 26, 1947} was the senior German intelligence officer in Paris during the German occupation of France in World War II. In 1944 he was in command of the German troops who murdered captured SAS men during Operation Bulbasket. These murders of POWs were a flagrant breach of the Geneva Convention, which Germany had signed. Kieffer was subsequently charged with war crimes. After being found guilty at his trial he was sentenced to death by hanging and executed on the gallows at Hamelin prison by Albert Pierrepoint.
