After completing his studies in sociology, political science, history with a Magister Artium degree, Steffen Müller retrained as a programmer. He worked for decades as a trainer for operating systems and software. After he was made redundant, he discovered the unprocessed files in the Archiv der Münchner Arbeiterbewegung, while looking for something meaningful to do. The files caught his interest because of the subject matter. Recording the content, researching further information and creating a presentation is a challenging and not yet completed task. There are many stories left to tell. Project "Evaluating and Publishing Files on Compensation Cases" (https://kittl.arbeiterarchiv.de).
