Dr. Herta Oberheuser killed children with oil and evipan injections, then removed their limbs and vital organs. The time from the injection to death was between three and five minutes, with the person being fully conscious until the last moment.
She made some of the most gruesome and painful medical experiments during World War II, focused on deliberately inflicting wounds on the subjects. In order to simulate the combat wounds of German soldiers fighting in the war, Herta Oberheuser rubbed foreign objects, such as wood, rusty nails, slivers of glass, dirt or sawdust into the wounds.
After World War II, in October 1946, the Nuremberg Medical Trial began, lasting until August of 1947. Twenty-three German physicians and scientists were accused of performing vile and potentially lethal medical experiments on concentration camp inmates and other living human subjects between 1933 and 1945. Fifteen defendants were found guilty, and eight were acquitted. Of the 15, seven were given the death penalty and eight imprisoned.
Herta Oberheuser was the only female defendant in the medical trial. She received a 20 year sentence but was released in April 1952 and became a family doctor at Stocksee in Germany. Her license to practice medicine was revoked in 1958.
