During the 1930s and 1940s, Rudolf-August Oetker was an active member of the Waffen-SS of the Third Reich. The company supported the war effort by providing pudding mixes and munitions to German troops. The business used slave labour in some of its facilities. A bronze bust of Richard Kaselowsky still sits within the company headquarters in Bielefeld. Kaselowsky was killed during an air raid on Bielefeld in 1944.[2] The Oetker Family is among those German families, who have profited most from their close relations to the Nazi regime.[3]

Richard Oetker, August Oetker's brother, took over as CEO in 2010.
