In page Andreas Baader:

"

Following their apparent suicides, the German government had the brains of Baader, Meinhof, Ensslin and Raspe removed for study at the Neurological Research Institute at the University of Tübingen.[1][2] Meinhof's brain contained scar tissue, the result of surgery to remove a benign tumor in 1962, that could have affected her behavior.[3] The results of the study of the others' brains are not known.[citation needed] Aside from the removal of his brain, a death mask was made of Baader. The brains of all but Meinhof have apparently been lost and cannot be accounted for by German authorities.[4]
