This is a portrait of the architect Wilhelm Riphahn (1889–1963). It is included in the portfolio ‘The Architect’, in the group entitled ‘The Artists’ within August Sander’s monumental photographic project ‘People of the 20th Century’. Architects were one of a number of artistic professionals photographed for this group, which also includes portraits of writers, composers, painters, sculptors, actors and performing artists. Based in Cologne, Riphahn worked for the Siemens architecture office and the office of the Taut Brothers and Franz Hoffmann in Berlin early in his career. During World War I and from 1925 to 1931 he worked with the architect Caspar Maria Grod, designing the Cologne UFA Palast in 1931. Built in a record five months and seating 3,000 people, it was the largest cinema in the west of Germany at that time.
