Carl Zuckmayer's play «Die Uhr schlägt eins» is particularly suited to an edition for students of German literature, culture and language, because its main theme is the youth of our day, with its dreams and potentials. For the purpose of clarity and to stress Zuckmayer's special contribution as a dramatist, the introduction to the text is divided into two parts: part I is devoted to giving an understanding of «Die Uhr schlägt eins» within the framework of Carl Zuckmayer's work as a whole and to a thematic analysis of the play; part II constitutes a biography which, being presented in note form, with dates in the margin, offers a clear picture of all the main events and developments in the life of the dramatist and can be used as a reference. The introduction is followed by a bibliography of selected works of Carl Zuckmayer, as well as selected literature on Zuckmayer. The text of the play is accompanied by footnotes throughout. A German-English vocabulary appears at the end of the book.
