Forced labor was a central component of the Nazi dictatorship. Between 1938 and 1945, around 13 million people were forced to perform forced labor in the German Reich. In Berlin alone, some 500,000 forced laborers were distributed throughout the city in around 3,000 camps and collective accommodations. At no time did so many people from other countries live in Berlin and have to work under duress. The project “Human Commodity” uses an interactive app to commemorate 99 sites of forced labor in Berlin and makes the stories of 99 forced laborers audible. In addition to central historical information, musicians present the pieces composed by Marc Sinan. The 99 audio miniatures are representative of all victims of Nazi forced labor. The Memorial was first presented in two parts on September 17, 2022. A ceremony was held at the Documentation Center Nazi Forced Labor – with lectures, music and guided tours of the site. In addition, sound artist Kaffe Matthews offered bike tours on her “Sonic Bikes” developed especially for the project. In the SPREEHALLE Berlin a photo exhibition on Human Commodity and the opening concert of the Marc Sinan Company could be experienced.
