August Sander worked on his monumental documentary project ‘People of the 20th Century’ from the mid-1920s until the end of his life. It comprises over 500 photographs classified into seven groups, which are further subdivided into more than 45 portfolios representing the social classes and professional divisions of the time. This is a photograph from the portfolio entitled ‘Political Prisoners’, from the group ‘The City’, that Sander compiled in the mid-1940s, after the end of World War II and the defeat of the National Socialist regime. The subject was a personal one for Sander, as his son Erich had been persecuted by the Nazis in 1934 and died ten years later in Siegburg Prison. Erich took all the photographs included in the portfolio during his imprisonment, smuggling them out to his parents and requesting that they pass them on to the relatives and friends of those depicted.
