This is a portrait of the Havemann String Quartet, which was founded in the early 1920s by Gustav Havemann (1882–1960), shown here on the far right (first violin). The other members of the quartet were Georg Kühnau (second violin), Hans Mahlke (viola) and Adolf Steiner (violoncello). They formed one of the most successful string quartets of their day, playing both classical and avant-garde music. Although Havemann initially conformed to National Socialist politics and became a leading musician of the Third Reich, he was expelled from the national musicians’ club when he intervened on behalf of the composer Paul Hindemith who had become a victim of the Nazi’s Degenerate Art campaign. The photograph is classified in the portfolio ‘The Performing Musician’ from the fifth group entitled ‘The Artists’ within August Sander’s monumental documentary project ‘People of the 20th Century’.
