The Museum of Modern Art quotes this summary of the art of Otto Dix
Otto Dix aggressively implies in this portfolio that sex is the force driving all men. In Apotheose (Apotheosis), fragmented body parts and leering faces orbit a grotesquely distorted prostitute, whose outsize genitalia mark the center of the composition. Dix believed in the utter incompatibility of men and women. He borrowed imagery conveying the epic conflict of the sexes from philosopher Friedrich Nietzsche's Thus Spoke Zarathustra, such as the juxtaposed moon and sun in Mann und Weib (Nächtliche Szene) (Man and woman [nocturnal scene]) and the cats slinking over moonlit roofs in Katzen (Cats). On the streets, meanwhile, traditional order—both moral and pictorial—breaks down. Die Prominenten (Konstellation) (The celebrities [constellation]) reveals Dix's skepticism toward exuberant promises of a better future: four ideologues share a single body, espousing a manifesto of love, fatherland, order, and Dada.
Although still indebted stylistically to the Expressionist techniques of distortion, the Futurist fracturing of picture planes, and the Cubist use of collage, Dix has already discovered the power of scathing social critique in these early woodcuts, which count as some of his first prints. He made woodcuts only briefly, between 1919 and 1920, and then gave up the medium entirely.Publication excerpt from Heather Hess, German Expressionist Digital Archive Project, German Expressionism: Works from the Collection. 2011.

The National Gallery of Australia provides some background information on Dix.
Otto Dix was born in 1891 in Untermhaus, Thuringia, the son of an ironworker. He initially trained in Gera and at the Dresden School of Arts and Crafts as a painter of wall decorations and later taught himself how to paint on canvas. He volunteered as a machine-gunner during World War I and in the autumn of 1915 he was sent to the Western Front. He was at the Somme during the major allied offensive of 1916.
After the war he studied at the academies of Dresden and Dusseldorf. Together with George Grosz, he was one of the leading exponents of the artistic movement Die Neue Sachlichkeit [New Objectivity], a form of social realist art which unsentimentally examined the decadence and underlying social inequality of post-war German society. With the rise of the National Socialists in 1933, Dix was dismissed from his teaching post at the Dresden Academy. He moved south to Lake Constance and was only allowed to continue practising as an artist after he agreed to relinquish overtly political subject matter in favour of landscape painting. Dix was conscripted into the army during World War II and in 1945 was captured and put into a prisoner of war camp. He returned to Dresden after the war where his paintings became more religiously reflective of his war-time experiences. He died in 1969
Otto Dix died in Singen, which at the time was West Germany.
