The first half of the twentieth century was an era of deep-seated upheaval for Austria: Two world wars, several changes of political system including a temporary loss of national autonomy, economic and monetary crises, and rapid technological progress came together to create a massive societal transformation. Each of these different aspects left its traces on the nation's educational system, thus also influencing the development of the TU Wien. This book, part 1 of volume 1, illustrates the most important developmental aspects of the history of the TU Wien from the early twentieth century to the end of the First Republic and the "Ständestaat".
