Otto Dix was a German artist and printmaker. His portrait paintings of Weimar society display a very distinctive, harsh style and the brutality of war. Dix joined the German Army in WW1 and was based in Dresden, and took part in the Battle of the Somme. After the war he began to paint again and was a member of the Berlin Secession group. His work was extremely critical of contemporary German society and by the time of WW2 his work was considered degenerative art by the Nazis. He was sacked as head teacher at the Dresden Art Academy and many of his paintings were destroyed. During later life, Otto Dix’s paintings were recognized by both East and West Germany as highly significant depictions of a crucial period of history in 20th century Germany.
Dix was a major figure in the Neue Sachlichkeit Movement and his paintings are also representative of the Dada and New Objectivity Art Movements- https://www.reproduction-gallery.com/artist/otto-dix/
