Daniel-Henry Kahnweiler was a German-born art collector, and one of the most notable French art dealers of the 20th century. He became prominent as an art gallery owner in Paris beginning in 1907 and was among the first champions of Pablo Picasso, Georges Braque and the Cubist movement in art.

Les Demoiselles d'Avignon is a large oil painting created in 1907 by the Spanish artist Pablo Picasso. Part of the permanent collection of the Museum of Modern Art in New York, it portrays five nude female prostitutes in a brothel on Carrer d'Avinyó, a street in Barcelona, Spain. The figures are confrontational and not conventionally feminine, being rendered with angular and disjointed body shapes, some to a menacing degree. The far left figure exhibits facial features and dress of Egyptian or southern Asian style. The two adjacent figures are in an Iberian style of Picasso's Spain, while the two on the right have African mask-like features. Picasso said the ethnic primitivism evoked in these masks moved him to "liberate an utterly original artistic style of compelling, even savage force” leading him to add a shamanistic aspect to his project.
