Felix Martin Julius Steiner (23 May 1896 – 12 May 1966) was a German SS commander known for his significant contributions during World War II. He played a pivotal role in the development and transformation of the Waffen-SS into a combat force comprising volunteers and conscripts from occupied and unoccupied lands. Steiner's remarkable military career included commanding several SS divisions and corps, and he was honored with the Knight's Cross of the Iron Cross with Oak Leaves and Swords for his leadership. Notably, he was chosen by Heinrich Himmler to establish and lead the SS Division Wiking, and later commanded the III SS Panzer Corps and the 11th SS Panzer Army in the defense of Berlin. Despite being imprisoned and investigated for war crimes after Germany's capitulation, Steiner was eventually released, later joining the U.S. Central Intelligence Agency to advocate for the rearmament of West Germany. His influence extended beyond the battlefield as he co-founded the Gesellschaft für Wehrkunde and was a founding member of HIAG, a lobby group advocating for the rehabilitation of the Waffen-SS. Steiner's legacy is intertwined with the complex history of the Waffen-SS, and his actions continue to be a subject of historical scrutiny and debate.
