In the 1920s, Nussbaum was one of the most important artist personalities in Frankfurt and made a considerable contribution to the cultural life of the city. At the Städel School, he headed a master studio but, after the seizure of power by the Nazis, was forced to step down because of his Jewish ancestry and fled to Palestine. Here, he presents his face in semi-profile, gazing out at the viewer with scepticism. The Impressionist play of shadow adds drama to the gaze. The collar of his painting smock refers to his profession as an artist, whereby the focus is laid on his emotional expression.
