This is a portrait of the Polish painter and printmaker, Jankel Adler (1895–1949). The photograph was taken in 1924, two years after Adler moved to Düsseldorf, where he taught at the Academy of Arts and became a friend of Paul Klee, who had a decisive influence on his work. The portrait belongs to the portfolio ‘The Painter’ from the fifth group entitled ‘The Artists’ within August Sander’s monumental documentary project ‘People of the 20th Century’. Like many of the other painters and sculptors that Sander photographed, Adler was loosely involved with the artists’ collective known as the Cologne Progressives. As an uncompromisingly modernist artist, both left-wing and Jewish, Adler was an enemy to the National Socialist regime. He fled Germany in 1933 to live first in Paris and later in Scotland and London. In 1937 his work was included in the infamous ‘Degenerate Art’ exhibition in Munich. All of Adler’s nine siblings were killed in the Holocaust.
