vii, 56 p. This thesis is written in German. / My thesis focuses on the question of how intertextuality can operate as a form of cultural memory. Drawing on the cultural-semiological model of intertextuality developed by Renate Lachmann, my analysis of Hermann Broch's novel <italic>Die Schlafwandler</italic> examines how the incorporation of intertexts enriches and changes the interpretation of a manifest text. I am focusing in particular on Broch's references to Johann Wolfgang von Goethe and Immanuel Kant in the chapters "Zerfall der Werte" to exemplify how intertextuality operates in this novel. The focus on two specific sources of intertextual references allows me a thorough analysis of the new interpretive dimensions that are created through intertextuality and at the same time the delineation of new perspectives for the further study of intertextuality in relation to Broch's work. / Committee in charge: Prof. Martin Klebes, Chairperson; Prof. Kenneth Calhoon, Member; Prof. Alexander Mathäs, Member
