George Grosz, born Georg Ehrenfried Groß and son of a café-owner. His parents were devout Lutherans. Grosz grew up in the Pomeranian town of Stolp (Słupsk).His mother ran the local officer's mess after his father died in 1901. At the urging of his cousin, started the young Grosz with a weekly art class at the local Painter cave. Grosz developed his skills further by making meticulous copies of scenes by Eduard von Grützner and by drawing imaginary combat scenes. From 1909 to 1911, he studied at the Dresden Academy of fine arts, where Richard Müller, Robert Sterl, Raphael Wehle and Oskar Schindler were his teachers. He then studied at the Berlin College of Arts and Crafts under Emil Orlik
Grosz reported in 1914 as a war volunteer but was declared unfit for military service in May 1915. After this he developed into a pacifist. He suggested caricature themilitarism, the hypocritical civil moral and the upheaval in the Metropolitan society to the jaw. Around 1920 he was involved in the Berlin Dada, for which he made under more socially critical and political collages . He was for some years a member of the Communist party KPD.  
In series lithographs as Ecce Homo he showed the glaring contrasts in the Weimar Republic: oily citizens and unemployed, judges and prostitutes, priests and assassins, generals and poor soldiers. The style is elementary and caustic. Under the influence of Cubism , he released both in his paintings as his graphic work on several small scenes on a flat surface together, in order to give a picture of the pandemonium of his time. Because of the ruthless realism is his work to the new objectivity group.
In 1932 was already immigrated to the United States, Grosz where he quieter and more conventional work made. The most interesting in this period are apocalyptic visions of nazi Germany during the second world war, influenced by Jeroen Bosch and Pieter Breughel. He also made a number of paintings with thin males, called stickmen.
