This is a portrait of Heinrich Hoerle (1895–1936) who founded the artists’ collective known as the Cologne Progressives with Franz Wilhelm Seiwert. Throughout the 1920s August Sander engaged in an ongoing dialogue on artistic, social and political issues with the Progressives. Like the other artists, he was deeply concerned with the question of how art could communicate the social and political realities of modern society. The organisation of his documentary project ‘People of the 20th Century’ according to thematic series of photographs representing the social types and structures of his time is an approach that was also used by the Progressives. In 1920 Hoerle produced twelve lithographs that he presented under the title of ‘Krüppelmappe’ (Cripple Portfolio). Sander included this photograph in the portfolio ‘The Painter’ from the group ‘The Artists’.
