Rudi Supek (Zagreb, 8 April 1913 – Zagreb, 2 January 1993) was a Croatian sociologist, philosopher and a member of the Praxis School of Marxism. Supek studied philosophy in Zagreb and graduated in 1937. He went to study clinical psychology in Paris, where he was when World War II erupted. He joined the resistance movement, but soon was captured and deported to the Buchenwald concentration camp, where he took part in the Buchenwald Resistance. After the liberation, Supek went back to Paris to continue living and studying there. In 1948, after the Informbiro Resolution against Josip Broz Tito's Yugoslavia, the leader of the French Communists Maurice Thorez asked Supek, who was a member of the French Communist Party, to attack Titoism. Supek refused to comply and returned to Yugoslavia. Howev
