From the mid-1920s until the end of his life, August Sander worked on his monumental documentary project ‘People of the 20th Century’, which has been described as a work of cultural and social history executed in the medium of photography. Over 500 are organised into seven groups representing the social structures and professional classes of the time. Group Six, ‘The City’, stands out for its loose arrangement of subjects, ranging from different city ‘types’ to events of everyday urban life. This portrait of an unknown woman is from the portfolio entitled ‘The Persecuted’, which depicts Jewish people who emigrated from Germany or were killed in the Nazi concentration camps. Sander added the portfolio to his project shortly after the end of World War II. It highlights the new absence of the German-Jewish middle classes, who had formed an important part of German social, cultural and economic life during the first half of the century.
