Kafka began studying law and philosophy in his native Vienna. He was soon drawn to Göttingen to Georg Elias Müller and then to Leipzig to Wilhelm Wundt, with whom he earned his doctorate. From Leipzig he traveled to Munich to Theodor Lipps with whom Kafka habilitated. It was probably during this time that he met Oswald Külpe. Kafka was one of the few psychologists who protested against Nazi ideology. It was said that with the help of a doctor friend he poisoned himself to the point that he was sent into early retirement. During the air raids on Dresden, Kafka lost everything and was seriously injured. Suffering from hunger, he was called from the Soviet-occupied zone to the University of Würzburg in 1947. Here he used all his strength to rebuild the institute and psychology. He also refounded the German Psychological Society in the American sector.
