August Sander (17 November 1876 – 20 April 1964) was a German portrait and documentary photographer. His first book Face of our Time (German: Antlitz der Zeit) was published in 1929. Sander has been described as "the most important German portrait photographer of the early twentieth century". Sander's work includes landscape, nature, architecture, and street photography, but he is best known for his portraits, as exemplified by his series People of the 20th Century. In this series, he aims to show a cross-section of society during the Weimar Republic.
