Diaries, especially war-diaries are often neglected in the literary studies, although specifically diaries are often offering an authentic view of emotions, thinking and behaviour or specific events. This master thesis attempts to contribute to the literary diary research and cultural studies of World War I. The object of investigation of this thesis are the diaries of two Jewish soldiers of World War I: The diary of writer and publicist Egon Erwin Kisch, already published by himself in the 1920s and the until now unpublished, handwritten notes of the physician Bernhard Bardach. Moreover, Bardachs diary is supplemented with a large photo collection of World War I (nearly 1,000 photos documenting the daily routine of the soldiers). The handwritten manuscript was transcribed by the author independently for this purpose and parts of it can be found in the appendix of the master thesis. Kischs diary on the one hand is a literary shaped writers diary and Bardachs records on the other hand are the notes of a physician, without any literary ambitions. The theoretical basis of the thesis is the essay Kriegslandschaft of the phenomenologists Kurt Lewin. Lewin, who has participated himself in World War I. In Kriegslandschaft he tried to represent the actually seen landscape as a construct that is shaped by experiences and ideas of the soldiers. Lewin developed six categories that highlight different areas of experience. On the basis of these categories, a scheme to analyse the diaries is developed. Furthermore, questions about areas such as historical tradition of the diaries and materiality of the manuscript, authenticity and variability of the statements, as well as writing motivation and content, are included in the studies.
