George Grosz (July 26, 1893 – July 6, 1959) was a German artist known especially for his caricatural drawings and paintings of Berlin life in the 1920s. He immigrated to the United States in 1933, and became a naturalized citizen in 1938. Abandoning the style and subject matter of his earlier work, he exhibited regularly and taught for many years at the Art Students League of New York. In 1959 he returned to Berlin, where he died shortly afterwards.

By 1914, Grosz worked in a style influenced by Expressionism and Futurism, as well as by popular illustration, graffiti, and children's drawings. His drawings was usually in pen and ink which he sometimes developed further with watercolor. Corpulent businessmen, wounded soldiers, prostitutes, sex crimes and orgies were his great subjects.

After his emigration to the USA in 1933, Grosz "sharply rejected his previous work, and caricature in general." In place of his earlier corrosive vision of the city, he now painted conventional nudes and many landscape watercolors. More acerbic works, such as "Cain, or Hitler in Hell" (1944), were the exception. In his autobiography, he wrote: "A great deal that had become frozen within me in Germany melted here in America and I rediscovered my old yearning for painting. I carefully and deliberately destroyed a part of my past."
