This thesis is dealing with the work of the dramaturge, translator and the theatre theorist Karel Kraus (1920 - 2014). The activity of this author is presented gradually with an accent on the chronology and domains of his production, as well as on the most significant subjects in his works. The main purpose of this thesis is to characterize and summarize Kraus's work as a whole unit. And there are primary sources (writings of Kraus) which are used to accomplish this intention. While the unit of Kraus's works is described step by step, we are also getting familiarized with his way of writing and his attitude. The thesis is extended of a supplement which consists of the bibliography of the essays and articles by Karel Kraus in the period from 2000 to 2014.
