August Sander (German, 1876–1964) was a German photographer whose career reached across both World Wars and the time in between. He was born in 1876, and has come to be known as an extremely influential portrait and documentary photographer. He opened his own studio in Cologne in 1909 and from there, his career as a portrait photographer took off. He began his most famous project entitled Citizens of the Twentieth Century for the purpose of creating a comprehensive portfolio of the German people during the Weimar Republic in the years between World War I and World War II. Sander was a firm believer in physiognomy as a way to decipher a person's personality and station in society. He divided the series into seven sections: The Farmer, the Skilled Tradesman, Women, Classes and Professions, Artists, the City, and the Last People (the handicapped, homeless, derelict). In 1929, a selection of 60 images from this series was published in Face of Our Time. As the Nazi regime took power, Sander came under fire, and a great amount of his photographic plates were destroyed. In 1942, Sander moved to a rural area, thereby protecting the remainder of his negatives. Sander’s career is prolific, and his archive contains over 40,000 images. He passed away in April of 1964.
