A German Flickr contact Elizabeth alerted me to the work of August Sander who assigned himself to make a photographic portrait of the German people in the 1920's and 1930's.
Sander Documents a wide range of people found in German Society of the period, there are portraits of Nazis, Industrialists, well known Artists, Peasants, Blue collar workers and the marginalised as in the image below.
Children in a home for the Blind (Duren 1930)
The sensitive approach of Sanders portraiture gives an equal value to all of his subjects.
Fitter (Cologne 1928)
