French dealer Paul Guillaume was one of the first to promote and sell African sculpture, beginning around 1911, even before opening his first gallery in Paris in 1914. Through Guillaume Apollinaire he was introduced to the art community, and within a decade became one of the best known dealers in modern art, handling works by Derain, de Chirico, Modigliani, Matisse, Picasso and others. In 1922-23 he became the primary source of art for Albert Barnes, founder of the Barnes Foundaiton in Merion, PA. Guillaume died prematurely in 1934. His widow, who subsequently married the architect Jean Walter, bequeathed the Walter-Guillaume collection to the French nation. It is currently displayed at the Musée de l'Orangerie in Paris.
