Karl Wolfgang Franz Count Motesiczky (born 25 May 1904, in Vienna; d. 25 June 1943) was an Austrian student of medicine and psychoanalysis and an active opponent of Nazism.
[2] From 1914 he attended preparatory high school, and from 1920 he also studied cello at the Vienna Imperial Academy of Music and the Performing Arts.
[2] Motesiczky became an author and a financial backer of Reich's Zeitschrift für Politische Psychologie und Sexualökonomie [de] (Magazine for Political Psychology and Sexual Economy).
After the German annexation of Austria on 12 March 1938, his Jewish mother and his sister Marie-Louise Motesiczky [de] fled the next day to the Netherlands.
[5] He continued his study of medicine at the University of Vienna and joined an informal psychoanalytical training seminary led by August Aichhorn.
Due to his classification as "mixed race (first degree)" by the Nuremberg Laws, Motesiczky was not allowed to continue his training when the seminar gained official recognition in 1941.
[13] The property was restituted to his mother and sister after the war and sold by them in the mid-1950s to SOS Kinderdorf,[2] an international charity that runs a chain of ‘villages’ worldwide for humanitarian work with children.
