The articles in this volume provide an academically thorough analysis of the history of the Austrian PORR AG under the Hitler regime in the years 1938 to 1945, ranging from the forced aryanization immediately after the “Anschluss” to the construction activities on various major projects in Austria and internationally. An important subject of research here is the treatment of the company’s (forced) employees. The development of PORR during the Nazi era and in the first postwar years, its differences notwithstanding, can be seen as typical of one of the major Austrian construction companies.
