Emil Reisch (1863–1933) was among Vienna’s leading classical archaeologists in the final years of the monarchy and the First Republic. As a full professor at the University of Vienna, director of the Austrian Archaeological Institute, and a member of the Austrian Academy of Sciences, in addition to holding numerous other university and state appointments, he exerted a decisive influence on the city’s academic landscape for decades. Yet the sheer breadth of his responsibilities meant that his own publications were progressively overshadowed. This, in turn, hastened his descent into obscurity within scholarly circles, and to date no comprehensive study of his life and work has been undertaken. The project seeks to redress this by systematically digitising, cataloguing, contextualising, and analysing correspondence addressed to Reisch, preserved in the archives of the Department of Classical Archaeology at the University of Vienna. The corpus will illuminate Reisch’s personal and institutional networks and underscore Vienna’s role as a hub of academic communication, education, and administration in the Classics around the turn of the twentieth century. The letters offer insights into university life, including international research relations, teacher–student dynamics, and matters concerning collections and museums; they also speak to historical turning points, notably the First World War.
