Ilse Hess, Gefangener des Friedens. Professor Karl Haushofer has said of his pupil:
'He was one student among others, not particularly gifted, of slow intellectual grasp and dull in his work. He was very dependent on emotions and passionately liked to pursue fantastic ideas. He was only influenced by arguments of no importance at the very limits of human knowledge and superstition; he also believed in the influence of the stars on his personal and political life... I was always disconcerted by the expression of his clear eyes, which had something somnambulistic about it...' (quoted by Francois Bayle, Psychologie et ethique du Nationalsocialisme).
