"The Painter of Berlin"
After democratic pluralism found its way into the officially supported art of Berlin after the end of World War I and the artist associations (Association of Berlin Artists, Berlin Secession, Free Secession, and Novembergruppe) for the first time provided a comprehensive overview of the artistic work in Berlin, Otto Antoine and Hans Hartig, the members of a jury founded for this purpose, represented the interest of the Association of Berlin Artists.
Otto Antoine was a member of the Association of Berlin Artists, which was founded in 1841. Later, he represented his fellow artists as a member of the association’s board and was repeatedly involved in the setting up of the Greater Berlin Art Exhibition. Eventually, he became an honorary member and honorary president of the association.
